The CMOS industrial camera LOGLUX^Òi5 CL

The CMOS industrial camera LOGLUX^âi5 CL is one of the latest and most modern products from the

‚industrial image processing CMOS camera‘ range of KAMERA WERK DRESDEN GmbH.

The camera can be considered a logically

consistent development of the well-known,

universally applicable predecessor model

LOGLUX^âHDRC4.

Main features of the CMOS industrial camera

LOGLUX^âi5 CL:

CMOS camera with free pixel selection

(progressive scan) and CameraLink^™data

interface

Figure 2 : Front and rear view of the CMOS industrial camera

LOGLUX i5 CL

Approx. 36 images/second (full frame), higher rates when a smaller frame size is used (up to

approx. 1500 images/second are possible)

Resolution: 1280x1024 pixels, 10-bit greyscale

>100 dB contrast/dynamic range

Digital image data interface

Possibility to pre-process the image data by means of the integral LUTs (look-up tables)

Spectral working range from 400nm to 1000nm

Sturdy continuously cast aluminum casing with C-type lens mount

Possibility to configure and control the camera, and transfer the image data, by means of a cable

connected to the host system (PC).

The CMOS industrial camera LOGLUX^âi5 CL is based on

a universal hardware concept which comprises a CMOS

large-area image sensor (FS), pre-processing unit (VV),

controller (SE), data interface (DS) and operating voltage

supply (SV).

In the pre-processing unit, the image data from the CMOS

image sensor can be linked up in real time with one of

three possible user-specific LUTs (look-up tables). In the

process, the image data can be replaced by function

values, e.g. arithmetic operations. By defining a greyscale

threshold in a LUT, for example, the camera can be made

to deliver the 'suitable' image material for a edge

recognition.

The camera firmware can be updated via an additional RS232 interface. Voltage is supplied from a

plug-type power supply unit (24V/6W; comes with the unit) or an SPS DIN rail power supply unit (24V

±10%).

The CMOS large-area sensor IBIS5

The sensor element used in the CMOS industrial camera LOGLUX^âi5 CL is a type IBIS5 CMOS

image sensor made by Fillfactory (Mechelen/Belgium).

It is a photo-optical component of the latest CMOS image sensor generation. Being a typical SOC

(system-on-chip), the sensor does not only accommodate the sensor (pixel) elements proper, but also

all peripheral analog and digital components required to deliver a noise-corrected 10-bit greyscale

value as an output signal.

Main features of the sensor are its high resolution of 1280 x 1024 pixels (XGA resolution), the wide

dynamic (contrast) range of up to 100dB, the integrated FPN (fixed pattern noise) correction of the raw

image data, and two shutter modes (rolling/curtain shutter and synchronous/snapshot shutter).

As regards the conversion process, the IBIS5 is an integrating, photo-optical sensor.

For more technical data please refer to the latest IBIS5 data sheet.

The following paragraphs describe selected functions of the sensor. Understanding these functions is

imperative to the proper use of the various functional units.

The dynamic (contrast) range of the IBIS5 sensor

In contrast to, say, CMOS sensors for multimedia applications, the IBIS5 has a very wide dynamic

(contrast) range. This parameter describes the sensor's capability to show both very bright and very

dark image parts in the active frame. The figure shows a CD ROM whose surface is diagonally lit by a

lamp from the front, with the LOGLUX^Òi5 CL set for a normal (approx. 67dB) and extended (approx.

100dB) contrast range, respectively.

Figure 4 : Example of a very high image contrast range

In the photo on the left side, neither the manufacturer's name nor the storage capacity nor the

maximum write speed can be read. On the right side, this information can be read without difficulty,

provided the printing quality is good. The photos were taken with the same overall integration time

(approx. 39ms).

Two dynamic ranges can be set on the IBIS5 sensor. In the first range of approx. 67dB, the sensor

exhibits an almost linear transmission function. The operating mode of the sensor is termed single

integration slope mode:

In the inactive state - the shutter of the sensor is 'closed' - a defined potential, i.e. electrical voltage, is

applied to the individual sensor cell which is shown simplified as a light-sensitive capacitor. When the

sensor shutter is 'opened', the photons hitting the sensor cell cause the potential to die away. When

the sensor shutter is re-closed after a defined time (integration or exposure time), the residual

potential of the sensor cell can be measured and translated into a digital numerical value.

By several successive integrations of the sensor cell potential with respect to time applying different

integration times, the second dynamic range - which is going to be described in more detail here - will

be extended to approximately 100dB. This working mode of the sensor is called multiple integration

slope mode and functions as follows:

The basis is the above described single integration slope mode. In contrast to it, however, at least one

more integration cycle is carried out in the multiple integration slope mode. After the expiry of the first

integration time, an initial potential which is approx. 18% lower than the potential before the first

integration cycle, is applied to the sensor cell. Before a third integration cycle and after the second

integration time, this initial potential is reduced by approx. 34%; and before a fourth integration cycle

and after the third integration time, the initial potential is reduced by approx. 54%.

Before a subsequent integration cycle, the above-mentioned initial potential is applied to those pixels

only which were completely discharged - i.e. over-exposed - in the previous integration cycle. The

residual potentials of all the other pixels are separately added to the residual potentials of the

subsequent integration cycles.

This means that very bright pixels require at least two, in some cases even four integration cycles with

the respective integration potentials and integration times, whereas very dark pixels may 'need' but a

single initial potential in up to four integration times to deliver evaluable residual potentials.

Upon the completion of the last integration cycle, the residual potentials of the pixels are inverted and

translated into digital numerical values.

Please note that the multiple integration slope mode does not work when the rolling shutter mode is

selected.

There are four registers (PROFILE_INIT0 / PROFILE_INIT1 / PROFILE_INIT2 / PROFILE_INIT3) that

allow the dynamic range of the IBIS5 sensor to be varied. They can be used to define both the number

of integration cycles and the integration time for the individual integration cycles. A valid integration

time is an integer number given in nanoseconds; if zero is entered in one of the above-mentioned

registers, the associated integration cycles is skipped.

Possible register settings are shown in the following examples:

This is a typical example of the single integration slope mode.

The only integration cycle is carried out at the highest initial

potential in 38.885ms.

The left photo of Figure 3 was taken with this setting.

This is an example of the multiple integration slope mode.

The first integration cycle is run at the third largest initial potential in

200ms. Thereafter, the second integration cycle is carried out at the

lowest initial potential in 10ms. Because of the first ‚long‘ integration

time, evaluable residual potentials are obtained for the dark pixels,

whereas in general very low residual potentials, or none at all, are

obtained for the bright pixels. As compared with the first integration cycle, slightly lower residual

potentials are obtained for the dark pixels as a result of the second 'short' integration time, while the

bright pixels now reach evaluable residual potential levels. This register setting is, thus, suitable for

images with primarily dark regions.

Another example of the multiple integration slope mode.

Four integration cycles are carried out here, with the integration

times being reduced by a power of ten each, starting from 35ms.

By a clever selection of the integration time length, a dynamic

(contrast) range of >100dB in the active frame can be implemented

in four integration cycles. The right-hand photo in Figure 3 was

taken with this setting.

When taking highly dynamic images, variations of the register settings may be necessary to get

optimum results.

The following procedure is recommended for setting the register:

First a suitable exposure time - preferably that in register PROFIL_INT3 - is set for the darkest region

of the frame. Thereafter, integration cycles are added one by one, preferably starting with register

PROFIL_INT2. The integration times of all integration cycles will then be summed up to give the

previously determined optimum exposure time for the darkest image regions.

Users of the LOGLUX^ÒLuxWare configuration tool are also recommended to apply the above

procedure. However, they have to enter the individual integration times into input fields ‚Kneepoint

1...3‘ instead of directly into the registers PROFILE_INT0...2, and into input field ‚Remaining time‘

instead of directly into PROFIL_INT3, respectively. The overall integration time (current integration

time) is displayed in input field ‚Remaining time‘.

The shutter modes of the IBIS5 sensor

The IBIS5 has two shutter modes, viz. the rolling or curtain shutter mode and the synchronous or

snapshot shutter mode. The working principles and resultant characteristics of the two shutter modes

are described below.

The working principle of the rolling or curtain shutter can be described by means of the following

graphic representation:

Figure 5 : Working principle of the rolling/curtain shutter and the imaging of moving objects

As is shown in Figure 4 (left), an object is imaged by recording individual lines. The capturing of a line,

in turn, is subdivided into three phases: resetting all pixels of a line, integrating all pixels of a line, and

reading out all pixels of a line. The content of a picture element of an image is not fixed until the

integration phase is completed. It should be noted that the integration phase for line 7, for example,

will not start until the integration phase for line 1 is complete.

When the camera is set to the ‚rolling/curtain shutter‘ mode and an attempt is made to capture a

moving object whose motion vector is normal to the sensor line readout vector, it can easily be seen

that the image of the moving object is distorted (Figure 4, right side). The degree of image distortion is

determined by the relation between sensor line readout speed and object speed. In most cases, this

distortion effect is unacceptable for image processing.

For this reason, the ‚rolling/curtain shutter‘ mode should, where possible, only be used for imaging

objects that do not move, or move slowly relative to the sensor line readout speed. In this case,

however, the image can be captured at very high image rates.

The working principle of the central or snapshot shutter mode can be described by means of the

following graphic representation:

Figure 6 : Working principle of the central/snapshot shutter and the imaging of moving objects

As is obvious from Figure 5 (left side), the object is here, too, produced by recording individual image

lines, and a line is also captured in three phases: resetting all picture elements of a line, integrating all

pixels of a line, and reading out all pixels of a line. But in contrast to the ‚rolling/curtain shutter‘ mode,

the reset and integration phases for all lines are connected up in terms of time. Only reading out the

individual lines is separate. This approach reveals a big advantage over the ‚rolling/curtain shutter’

mode: The image of a moving object is free of distortions (Figure 5, right side). However, this

advantage is at the price of the image rate: A comparison of Figures 4 and 5 (left sides) shows that the

‚central/snapshot shutter‘ mode does not permit a time-staggered readout of the sensor lines.

The ‚central/snapshot shutter‘ mode should be used whenever undistorted images of moving objects

are needed. Compared with the ‚rolling/curtain shutter’ mode, the image rate is lower.

The look-up tables (LUTs) of the CMOS industrial camera LOGLUX^Òi5 CL

The possibility of immediate real-time data manipulation in the camera is a great advantage of the

CMOS industrial camera LOGLUX^âi5 CL. In addition to the fixed-programmed functions such as bit

shifting operations, three user-specific, configurable look-up tables (LUTs) are available for the

purpose.

A LUT is a user-definable function value table in which a function value can be assigned to each of the

2¹⁰, i.e. 1024, 10-bit greyscale values of the IBIS5 sensor. At a constant 12ns signal delay, this value

assignment occurs almost in real time.

Using the LUTs is explained in more detail in section „Function group ‚LUT programming‘“ of chapter

„Description of the LUGLUX i5 CL register set“.

The CameraLink^™image data interface

For a fast and safe transmission of the image data from the camera to the host system (PC/IPC), two

modern transmission concepts have been implemented in the CMOS industrial camera LOGLUX^âi5

CL.

As an improved version of the LVDS (low voltage differential signal) technique, the CameraLink^™

standard, which features a large transmission bandwidth and a very good transmission safety, is

nowadays considered a quasi standard for data interfaces as used in industrial image processing. In

addition to the image data transmission from the camera to the host system, it is also possible to

control and configure the camera from the host system via up to four integral serial ports. A distance of

up to 10m between the camera and host system can be bridged without any auxiliary devices

(repeaters or the like) being necessary.

For further technical data see the technical documentation of the CameraLink^™standard.

The complete LOGLUX^Òi5 CL SET camera system

The LOGLUX^âi5 CL SET is a complete package designed to facilitate and speed up the

understanding and operation of the CMOS industrial camera LOGLUX^âi5 CL.

The package includes an industrial camera LOGLUX^âi5 CL (without lens), a PC plug-in card

(MATRIX Vision MVtitan-CL), a general data cable, an RS-232 data cable (3m long each), a split

adapter (for splitting up the power supply, RS-232, trigger input and switching outputs), a plug-in

power supply unit (24V/6W), and a CD ROM with driver and software for the Microsoft^âWindows

operating systems 2000 and XP.

Optional accessories

Various CMOS industrial camera LOGLUX^âi5 CL accessories are available from ourselves and third

parties, among others lenses, customized data cables, DIN/EN rail power supplies, media converters,

etc. Please see our current product range and links to other products on our website (www.kamera-

The system requirements for IPC systems are similar to those for desktop PC systems; for reasons of

the 'tougher' use conditions, more exclusive components may occasionally have to be chosen. For

configuring an IPC system, just contact a systems house of your choice.

With the exception of the real-time recording of large image data streams (e.g. AVI captures in full

frame and at full frame rate), normal operation of the camera will be basically possible also with a

minimum host system configuration, however, some difficulties might occur.

In view of the numerous existing PC/IPC system configurations it is impossible to guarantee that the

full scope of camera system functions can be used in every configuration. In any case, a sound basis

of a successful start-up and trouble-free operation is a minimally equipped host system (only the

graphics and framegrabber cards are installed) that meets the above-mentioned requirements and has

a newly installed operating system.

Installation of the CameraLink^™PC plug-in card MATRIX Vision MVtitan-CL

The type MVtitan-CL CameraLink^™PC plug-in

card is a universally applicable and powerful

framegrabbing card for any application. Its

main components are an integral image

processor (TM1300), a large memory for the

software and data (8MB standard, optional:

<=32MB), and two plug connectors for two

base and one medium CameraLink^™ports.

Please consult the manufacturer's manual

when installing the PC plug-in card.

Note: You need to have administrator

rights for the respective PC if you want to

install hardware or software components!

Once the plug connectors and data cables have been safely connected, the operating voltage (24 V

±10%) can be applied to the camera.

Caution: Always use the plug-type power supply unit supplied with the CMOS industrial camera

LOGLUX^Òi5 CL SET, or DIN bus-bar type 24V power supply units which are suitable for

industrial control systems (PLCs)! Always connect the camera to a separate power supply!

Readiness for operation is indicated by the continuously lit green status LED on the rear of the CMOS

industrial camera LOGLUX^Òi5 CL.

The CMOS industrial camera LOGLUX^Òi5 CL is now ready for operation. The next step is the

installation of the ‚LOGLUX^ÒLuxWare‘ configuration tool.

Installation of the LOGLUX^ÒLuxWare configuration tool

Once the CMOS industrial camera LOGLUX^Òi5 CL has been properly prepared, the installation of the

LOGLUX^ÒLuxWare is very easy.

Description of the LOGLUX^ÒLuxWare configuration tool

The philosophy

The LOGLUX^âLuxWare configuration tool automatically finds the interfaces of the PC/IPC system and

the cameras connected to the system. The user selects the camera to be configured.

Owing to the logical tree structure principle applied, the complex functions of the IBIS5 CMOS image

sensor used in the CMOS industrial camera LOGLUX^Òi5 CL are easy to understand and handle. A

plausibility check of the settings is made so that faulty operations are largely excluded. In many cases

only a mouse is required for setting the parameters.

Professional users have full access to all relevant sensor functions at register level by using a terminal

program which is an integral part of the LOGLUX^âLuxWare. Moreover, this form of configuration is

fully scriptable, i.e. all settings can be logged and stored as an ASCII file and transferred from one

platform, e.g. Microsoft^âWindows, to another, e.g. UNIX/Linux. It is primarily the programmers who

will benefit from this function.

All camera settings can be stored in so-called user profiles which are re-loaded when needed. These

user profiles remain stored in the camera itself even after disconnection from the power supply.

It is a special feature of the CMOS industrial camera LOGLUX^Òi5 CL that the user can manipulate the

image data in the camera using up to three selectable look-up tables. The LUT load and storage

functions required for the purpose are provided by the software.

The start menu

When starting the software for the first time, a

window will appear after some time that shows

the image processing (IP) hardware of the PC

which is connected

to the

existing

framegrabber, FireWireÔ and/or RS-232 ports.

A query window will appear in all following

program starts, asking the user if the IP

hardware settings of the previous program start

are to be used again or if an IP hardware scan

as referred to above is to be made.

When selecting the LOGLUX^Òi5 CL cameras

connected to the respective ports (the camera

names are displayed), the following should be

noted:

Cameras plugged into RS-232 ports do not

deliver a live image with the configuration tool.

Where a camera image is needed, the viewing

software of the framegrabber or a suitable

third-party software should be used.

Cameras connected to the other ports deliver

an image right away when the configuration

tool is activated. All the user has got to do is

adjusting the image to a size that fits the

desktop PC.

A camera is activated by highlighting its name

in the 'Camera selection' window and then

clicking button 'Connect' . Should a camera not

be found, another hardware scan can be

started by clicking button 'Scan'. Pressing

button 'Cancel' will end the program.

The ‚Exposure‘ profile menu

The conversion function of the camera in the central shutter mode is set in this menu; this means most

of the settings will not be available until the 'Synchronous shutter (snapshot)' mode is activated in the

'Sensor' profile menu.

For a reasonable and fast selection of the options in this menu, the respective chapter in the camera

manual (The dynamic (contrast) range of the IBIS5 sensor) is recommended to be thoroughly read.

With 'Exposure precalculation' and 'Manual

exposure configuration' the user is given two

independent possibilities of adjusting the

conversion characteristic of the camera sensor.

First the integration time base must be set

under 'Exposure precalculation', with the

choice being between the current integration

time or a new total integration time ('User') or

the maximum time possible under the current

auto trigger rate ('Trigger'). When selecting

'User' the user must give the 'Total time' in ms.

Then, by means of two functions (logarithm of

base x, root of base x), the user can

approximate the sensor conversion function for

up to another three integration times to choose

from. To this end, the user highlights under

'Mode' the desired conversion function to be

approximated, and enters the value of the base

of the conversion function to be approximated

under 'Scale' . Finally, the accuracy of the

conversion function approximation is defined

by selecting the number of integration steps in

the 'Slopes' box. All settings are activated by

clicking button 'Apply'.

Under 'Manual exposure configuration' the user

is given the possibility to define the shape of

the sensor conversion characteristic by

entering the integration time number and value

of up to three more integration steps. .Entering

a valid integration time in 'Last slope' - this is

absolutely necessary if the above option is not

made use of - results in an exposure at a single

integration time ('single integration slope'). By

entering more valid integration times, exposure

at up to four successive integration times can

be implemented. Below the 'Last slope' input

Figure 16 : The ‚Exposure‘ profile menu

field are displayed the total exposure time and

the frame rate which depends on the camera configuration in the currently used profile. The value

shown in the figure can be considered a good value.

The raw (i.e. not pre-processed) sensor greyscale value versus object light intensity diagram gives a

survey of the sensor conversion function in the individual integration steps.

The ‚Sensor‘ profile menu

Sensor-specific parameters are entered in this menu. These include the pixel clock rate, the shutter

mode, the ADC amplification, and the gamma correction option.

The pixel clock rate of the camera can be set in

the 'Pixel clock' box. The frame readout time is

displayed below the box.

One of the two sensor shutter modes, i.e.

synchronous shutter or rolling shutter, can be

selected under 'Shutter'.

Under 'Amplification' the user can set the

amplification factor for the analog amplifier

downstream of the sensor in 6 increments.

Default is 1.

Note: For the following reasons, the

amplification factor should not be changed in

industrial image processing applications:

The proper calibration of the camera is no

longer guaranteed.

The pixel values are falsified through the

amplification limitation.

The signal noise would be amplified and the

desired improvement of the image brightness

cannot be achieved.

'Save as:' allows the user to save the live

image as an image file or video sequence

(button 'Image' or 'Sequence') to a data

medium. When storing it as a video sequence,

the user has the choice between a continuous

stream of frames (option 'Continous Stream') or

given number of successive frames

('Sequence length'). In both cases, the file

stream (AVI or raw data format) storage

process can be cancelled by repeatedly

clicking the 'Sequence' button which now reads

‚Stop‘.

Description of the LOGLUX^Òi5 CL communication log

The configuration data are exchanged between the host system (PC/IPC) and LOGLUX^Òi5 CL

camera by way of a line-oriented ASCII log. This method allows a platform-independent configuration

of the camera from any terminal.

All configuration commands consist of an command character string of up to four characters (letters)

and of max. four parameters, depending on the command.

Command and parameter are separated by a space character ($20, 'Space bar'). By actuating the

ENTER key ($0D $0A) - alternatively, by appending a nil character ($00) - the configuration data are

sent to the camera.

A comment may be appended to the configuration data by using a semicolon; the characters following

the semicolon are ignored as configuration data.

The following commands are available:

The above notation method is applied both to parameters transmitted to the camera and to data output

from the camera.

In case of the parameters, left-hand zeros may be omitted. Strings up to a length of 32 characters are

accepted.

The camera responds to a command request in a chronological order. However, prior to or after the

request for a command a message may be sent which is not related to that command.

Every line of a message or response is closed with a cr character ($0D).

Messages always have the following format:

Table 5 : List of register initial values of function group 'camera configuration'

PROFILE_PIXELCLK The register specifies the frequency of the pixel clock in Hz. The pixel clock

has an influence on a number of parameters, among them the image readout

rate, and may lead to undesired effects, e.g. the fading of the last pixel read

out, if unfavorably set.

Example:

w $102 #20000000 ;Pixel clock rate is 20 MHz

PROFILE_TRGSOURCE

The register describes the trigger source and the type of triggering. A single

snapshot, snapshot sequence or continuous "snapshot" can be triggered by

an external trigger signal, by signal CC1 (camera control 1) applied to the

CameraLinkä interface, or by setting bit 0 (corresponds to a register value of

1) in the PARAM_TRIGGER register. This releases a clock generator which

generates the trigger signals for the sensor at the desired frequency and in the

desired number. In the case of autonomous camera systems which are not

externally triggered, the camera can trigger itself during booting.

Example:

w $103 #3

;Trigger via TRegister

PROFILE_TRGDELAY

The register specifies a delay of the trigger event in nanoseconds. The actual

delay time is rounded to comply with the pixel clock accuracy (e.g.

TRGDELAY = 80 Þ 75.76ns delay at 66 MHz pixel clock rate ). There is also

a hardware-dependent delay in addition to the set delay time. Among others,

this hardware-dependent delay is determined by the camera-internal electrical

isolation of an optical coupling device (transmission time) or by the slope

(edge steepness) of the 24V trigger signal.

Example:

w $104 #1000

;delay is 1us

PROFILE_TRGRATE The register specifies the rate, or frequency, of framegrabbing (in Hz, or

snapshots per second) after triggering for a sequence of snapshots or a

continuous "snapshot" (video). Where the readout speed of an image is

sufficiently low, the actual image rate corresponds to the framegrabbing rate,

with the following condition having to be satisfied:

PIXELCLK / (WIDTH * HEIGHT) < TRGRATE

Otherwise, the framegrabbing rate is limited in dependence of the readout

speed to the maximum possible framegrabbing rate value.

Example:

w $108 #30

;Image rate is 30 Hz

PROFILE_SMODE

This register specifies the framegrabbing mode of the camera triggering

system. A single snapshot, sequence of snapshots or video can be generated

upon triggering.

Example:

w $10A #1

;Trigger for single snapshot

PROFILE_TMMODE Register PROFILE_TMMODE activates one of the available LUT functions

serving the link-up with the incoming image data:

The image data are subtracted from the constant 1024 which results in an

inversion of the image data.

The image data are shifted to the right bit by bit (by n bits). Zeros are

inserted at the most significant bits (MSB), the lowest significant bits (LSB)

get lost.

The image data are subtracted from the constant 1024 which results in an

inversion of the image data. Simultaneously, the image data are shifted to

the right bit by bit (by n bits). Zeros are inserted at the most significant bits

(MSB), the lowest significant bits (LSB) get lost.

The image data are shifted to the left bit by bit (by n bits). Zeros are

inserted at the lowest significant bits (MSB), the most significant bits (LSB)

get lost.

The image data are subtracted from the constant 1024 which results in an

inversion of the image data. Simultaneously, the image data are shifted to

the left bit by bit (by n bits). Zeros are inserted at the lowest significant bits

(MSB), the most significant bits (LSB) get lost.

A test image is displayed. The region of interest is subdivided into fixed-

size squares, and each square is filled with a graduated greyscale

extending from top left to bottom right.

LUT’s ‚User LUT 1‘ to ‚User LUT 3‘ can be filled with user-specific function

values (see „Function group ‚LUT programming‘“).

Example:

w $10C $0601

;User LUT 1 is selected

PROFILE_SW0SOURCE

PROFILE_SW1SOURCE

This register describes the source of switchport signal 0 or 1. A switchport

signal may be generated by the trigger module upon the event ‚Trigger‘, ‚Start

of Integration‘ (SOI) or ‚End of Integration‘ (EOI), or due to a rising slope of

signal CC2 or CC3 (camera control 2/3) via the CameraLinkä interface.

Note: Events SOI and EOI will not occur in the rolling shutter mode as there is

no controlled integration time and, consequentially, no configured switchport

activities.

Example:

w $10E #6

;Switchport 0 upon event Reg.

PROFILE_SW0POL

PROFILE_SW1POL

The register describes the polarity of switchport signal 0 or 1. If register

PROFILE_SWxSOURCE is set to OFF, the switchport level can be directly

controlled by register PROFILE_SWxPOL.

Example:

;Switchport 1 is low-active

PROFILE_SW0DELAY

This register specifies a delay time for switchport signal 0 or 1. The actual

delay time is rounded to comply with the pixel clock accuracy (e.g.

TRGDELAY = 80 Þ 75.76ns delay at 66 MHz pixel clock rate). There is also a

hardware-dependent delay in addition to the set delay time. Among others,

this hardware-dependent delay is determined by the camera-internal electrical

isolation of an optocoupler (transmission time) or by the slope (edge

steepness) of the 24V trigger signal.

Example:

w $110 #10000

;Switchport 0 delay 10 us

PROFILE_SW0LEN

PROFILE_SW1LEN

The register specifies a pulse length for switchport signal 0 or 1. The actual

delay time is rounded to comply with the pixel clock accuracy (e.g.

Example:

PROFILE_XSTART

PROFILE_YSTART

PROFILE_WIDTH

PROFILE_HEIGHT

The register specifies the start position left of the visible sensor frame. The

value must represent an even number of pixels and satisfy the condition

PROFILE_XSTART < 1280 – PROFILE_WIDTH.

Example:

w $130 #100

;X start coord. is 100

The register specifies the start position above the visible sensor frame. The

value must satisfy the condition

PROFILE_YSTART < 1024 – PROFILE_HEIGHT.

Example:

w $132 #150

;X start coord. is 150

The register specifies the width of the visible sensor frame. The value must

represent an even number of pixels and satisfy the condition

PROFILE_WIDTH < 1280 – PROFILE_XSTART.

Example:

w $134 #800

;frame width is 800 pixels

The register specifies the height of the visible sensor frame. The value must

must be entered in register PROFILE_INT3 for the single integration slope

mode; the other registers are to be filled with zeros.

The following conditions must be met to display a sensor frame as a live

image:

No integration time value must be lower than:

PROFILE_INTX >= 4000 * (40^.10⁶/ PROFILE_PIXELCLK)

Additionally, no integration time except the last may be lower than:

PROFILE_INTX > 4000 * (3.52^.10¹²/ PROFILE_PIXELCLK)

in the multiple integration slope mode.

Example:

w $138 #24000000 ;single int. SMode with 24ms

PROFILE_SHUTTER The register specifies the sensor shutter principle. Please note the multiple

integration slope mode is not possible when selecting the rolling shutter and,

thus, registers PROFILE_INT0, PROFILE_INT1, PROFILE_INT2 and

PROFILE_INT3 are inactive. The integration time is here determined by the

image readout rate.

Example:

PROFILE_SUBSAMPLE

w $148 #1

;rolling shutter mode

The register specifies whether or not a subsampling of the lines and/or

columns of the sensor shall be carried out.

Example:

w $149 #3

;X/Y Subsampling

PROFILE_AMLIFIER The register specifies the amplification factor of the analog amplifier

downstream of the sensor. The register value should not be changed for the

following reasons:

The proper calibration of the camera is no longer guaranteed.

The pixel values are falsified through the amplification limitation.

The signal noise would be amplified and the desired improvement of the

image brightness cannot be achieved.

Example:

w $14A #1

;Ampl.factor is 5.25

PROFILE_CALIB

The register specifies the calibration routine for the sensor.

The output amplifier is calibrated during every line blanking period. The fast

mode (#0) can force a calibration to be carried out during one clock cycle. This

is, however, not as accurate as would be desired, and thermal noise would be

unavoidable during calibration; in contrast thereto, the slow calibration mode

(#1...#3) is incremental and free of any thermal noise. Some 200 or more

"slow" calibrations have the same effect as one "fast" calibration. The differing

"slow" calibration modes may be set at the start of an image (#1) or any line

not yet read out (#2) or both together (#3).

Example:

PROFILE_PRECHARGE

w $14B #1

;slow image calibration

The register is set either to line-by-line or to permanent column-by-column

precharging.

In some applications, it may be necessary to use the continuous charging of

the pixel columns instead of the precharging with every line scanning

operation.

PARAM_VERSION

PARAM_EVENT

This register allows the camera to be identified from the host register.

Events can be generated in the camera by entering data in this register.

These events are sent to various modules such as the trigger or switchport

module. Functions can be triggered in the respective module if the event

If the value $04 (event register) had been entered in register

PROFILE_TRGSOURCE, a write access to register PARAM_EVENT using

the value $01 will trigger a framegrabbing process. This could be done to

simulate the response of the camera to an external trigger signal.

PARAM_INITPROFILE

The register permits the factory (default) settings of camera profiles 1 to 4 to

be reset. The register content of the respective target profile will be irrevocably

overwritten by the register content of the source profile.

Example:

PARAM_COPYPROFILE

w $905 $13

;initializes P1 with P3

The register permits camera profiles 1 to 8 to be given identical register

contents. The register content of the respective target profile will be

irrevocably overwritten by the register content of the source profile.

Example:

w $906 $62

;copies Profil2 to Profil6

Three register banks ($10000 ... $107FE for LUT1, $11000 ... $117FE for LUT2 and $12000 ...

$127FE for LUT3) are available for three user-specific LUTs. In addition to the function values y

allocated to each of the possible 1024 greyscale values x of the sensor, also a description of the

respective LUT functions is contained in these register banks.

Prior to the word-wise filling of the LUTx with function values, the respective erase sequence must be

entered into register TMFLASHx_ERASE_QUADLET. It is not possible to overwrite individual function

values in a LUT.

Example:

;1024th function value LUT1

The example describes what function values need to be entered in the user-specific LUT1 to generate

an inverted image (provided the missing function values are added in the above-mentioned manner).

Programming aids are recommended to be used for the generation and programming of the function

values. Two such aids are included in the software package for the CMOS industrial camera

LOGLUX^âi5 CL. One is a MathCADÔ 2000 document which permits the function values to be easily

generated and saved in a file by defining the corresponding mathematical functions. The other is a

simple DelphiÔ 6 program allowing the function values generated by the afore-mentioned document

to be programmed into the camera 'in one go'. Should the MathCADÔ 2000 application not be

available, any other suitable program can be used to generate the function values. In this case, if the

above Delphi 6 program is intended to be used for programming, the function value file should have

the following format:

The separating character for every function value is [CRNL, carriage return + new line]. This

character has the same effect as actuating the ENTER key.

The file must comprise 1024 unsigned integer function values.

The value range must not exceed the limit 2¹⁰-1 (1023).

The end of the file shall read [file name].LUT.

Notes on updating the firmware for the LOGLUX^®i5 CL camera

General information

As is the case with all consumer and industrial goods that allow their functions to be serviced,

improved or extended by software, the updating of the firmware is a sensible matter. Even if there are

intelligent and safe ways of updating, operator errors can be remedied to a limited degree only. For

this reason, the following should be noted when updating the firmware:

Take the time to read this chapter carefully and don't rush things when updating the firmware!

Once damage has occurred, it will surely take longer to remedy it!

Manual: CMOS Industrial Camera LOGLUX^Òi5

Do not panic when a firmware update fails! It is certainly not the camera that is defective, but one of

its functions will not properly work. In such a case, just send the camera to KAMERA WERK

DRESDEN GmbH to take care of the trouble.

Create a 'safe environment': Make sure the connections made on the camera and PC/IPC are

mechanically safe, and see to it that the camera and PC/IPC are properly powered.

For a firmware update, always use the safest and fastest communication method between the

camera and PC/IPC, if possible. Though one of the serial ports of the CameraLink™ interface may

be used for an MCU firmware update, the RS-232 port will be the better solution.

And last but not least an old thumb rule: ‚Do not change a running system!‘, i.e. do not update the

firmware unless it is absolutely necessary.

Components of a firmware update for a LOGLUX^®i5 CL camera:

an MCU firmware update file (*.txt)

an FPGA firmware update file (*.bin), and

the LOGLUX^®LuxWare PC software

Some functions of the above-mentioned components depend on the availability of functions in other

components. For this reason, it is advisable to check if a new version of the LOGLUX^®LuxWare

software is available when, for instance, the MCU firmware is updated. On the other hand, an

extension of the LOGLUX^®LuxWare functions usually calls for a complete firmware update of MCU

and FPGA.

An exception is the firmware update for the FPGA which may have user-specific functions and is, thus,

not so closely coupled to the other components.

The following firmware update procedure is recommended:

The firmware update files

Prior to updating the firmware, the user must first unpack the firmware files provided by KAMERA

WERK DRESDEN GmbH in form of a zip or other file, and load them into a folder of his choice.

Establishment of a serial connection

Plug a null modem cable into the RS-232 port (split cable!) to

connect the camera to the PC/IPC.

Note: It is strongly recommended to use the RS-232 port of the

camera for a firmware update!

Putt he camera into operation and start the LOGLUX^®LuxWare

PC software.

In the start menu, select the desired camera in window ‘Camera

Selection‘ (image processing hardware scan, see chapter

‘Description of the LOGLUX^®LuxWare configuration

software/The start menu‘), then click ‚Connect‘.

Note: For the purpose of a faster data transmission during an

update, the baud rate of the serial RS-232 port is recommended to

be set to '115000' kbaud (in menu ‚Camera Globals‘).
