6. Functions and Operations

In the following the format shown in “7.5. CV-M2 command list” are used for function

commands and parameters.

6.1. Basic functions

The M2 camera is a progressive scan camera with 10 or 8 bit video output in single or dual

channel Camera Link. On a BNC connector a standard composite video output CCIR or EIA for

monitor use is found. The image covers the full format, but the resolution is much lower than

the digital video output.

An iris video signal can be used for lens iris control if the camera is in continuous mode or Reset

Continuous Trigger mode.

A knee function (and gamma for single channel) makes it possible to cover high contrast scenes.

The CV-M2 camera has 1/2, 1/4 or 1/8 partial scanning. Programmable partial scan, where the

start line and the number of lines can be selected in 1line increments is also available.

There are 5 trigger modes. Normal continuous, reset continuous trigger, edge pre-select, pulse

width control, edge pre-select burst trigger and PIV trigger. (PIV, Particle Image Velocimety).

The Sensor Gate Control can be used in normal continuous mode together with strobe flash.

The accumulation can be LVAL synchronous or LVAL a-synchronous.

In the following some of the functions are shown in details.

6.1.1. Dual video output

The video read out through Camera Link can be via a single or via double channels. (OS=0 for

single channel, OS=1 for dual channel.) If dual video outputs are used, the frame grabber PC

should reconstruct the image frame from the 2 half images.

6.1.2. Burst trigger

With the burst trigger function TR=4, five previous set edge pre-selected programmable

exposures can be done with a single trigger pulse. The five shutter times can be set with BSH1

through BSH5. (1H through 1216H.)

6.1.3. Restart continuous trigger mode

The RCT mode makes it possible to use a lens with video controlled iris for intelligent traffic

surveillance applications. TR=2. The camera is running continuously, and the iris is controlled

from the iris video output. When a trigger pulse is applied, the scanning is reset and restarted,

the previous signal is dumped with a fast dump read out, and the new triggered exposure is

started. This fast dump read out has the same effect as “smearless read out”. Smear over

highlighted areas are reduced for the triggered frame.

6.1.4. PIV mode

The Particle Image Velocimetry mode can be used in applications where 2 images should be

taken with a very short time interval. TR=5. It can only be used with strobe flash or lasers as

illumination. The first accumulation time is 4 µsec. The second is as long as the time for a full

frame.

6.1.5. Sensor Gate Control

This function is for applications where a strobe flash is the only illumination, and where the

exact time for the strobe firing is not known. The time window for the strobe firing can be up to

several frames. The resulting video read out can also be delayed by this function. It makes the

synchronization of the frame grabber more flexible.

The Sensor Gate Control signal will inhibit the internal SG signal so the accumulation can

continue. The sensor gate control signal can be synchronized by the FVAL signal.

This function will only work in normal continuous mode. TR=0. The function is on if SG=1.

The SG signal is an internal signal, which is low when the accumulated charge on the photo

diode array is transferred to the vertical ccd registers for read out.

When the Sensor Gate Control input is high, the internal SG pulse is inhibited, and the signal

accumulation on the photo diode array can take place. When the strobe flash is fired, the Sensor

Gate Control signal can be low. The resulting video is then read out after the first FVAL (or SG),

following the falling edge of Sensor Gate Control signal.

The knee functions can compress the signals in the highlighted areas. The slope over the knee

point is only 20%. The Knee point can be adjusted from 712 to 1023. With the knee at 890, the

camera can reproduce scene highlight up to 175%. The image contrast is reduced to 20% for

scene luminance higher than the knee point.

This function can be used in applications where the scene brightness is divided in an area in

6.2.7. LVAL synchronous accumulation

With LS=0, the accumulation will start synchronously with LVAL. The trigger pulse should be

longer than 2 LVAL intervals, and the accumulation will then start at the first LVAL after the

trigger leading edge. The exposure start delay will be up to 1 line. (Single channel 47.9 µsec.

Dual 27.3 µsec).

In EPS mode the exposure stops 0.5 L after the selected shutter time, (in number of LVAL).

In PWC mode the exposure stops 0.5 L after the first LVAL after the trigger trailing edge. It

results in up to 1 LVAL jitter.

In LVAL synchronous accumulation mode a new trigger can start a new exposure during the

previous frame read out, but the exposure may not be finished before the frame is read out. It

makes it possible to have a trigger rate close to the frame rate. (1 FVAL + 3 LVAL).

Important notes on using this mode.

In LVAL synchronous PWC mode exposure jitter up to 1 LVAL can be the result, if the trigger

trailing edge is not synchronized to LVAL.

6.2.8. LVAL a-synchronous accumulation

With LS=1, the accumulation will start immediately after the trigger leading edge.

The exposure start delay will be 156 clk. pulses after the trigger. It is 3.9 µsec.

In EPS mode the exposure stops 0.5 L after the selected shutter time, (in number of LVAL).

In PWC mode the exposure stops 0.5 L after the trigger trailing edge.

A new trigger must not be applied before the previous frame is read out. (FVAL is low).

The minimum trigger interval should be longer than the exposure time + 1 FVAL+3 LVAL.

Important notes on using this mode.

In LVAL a-synchronous PWC mode there is no exposure jitter.

Partial scanning has 3 pre-selected vertical centred areas 1/2, 1/4 and 1/8. SC=1 through SC=3.

With SC=3, the start and the height of the partial scanned area can be programmed with 1 line

interval. The start line can be programmed with PS=1 through 1151. The scanned height can be

programmed with PC=50 though 1200. Partial scanning will operate with single or dual channel

output. Partial scan is done by a high-speed dump read out of the areas over and under the area

of interest. This partial scanned area is read out with normal speed. The high-speed dump read

out (Front of Frame and in Back of Frame) is done with a speed 18 times faster for single

channel, and 10 times faster for dual channel.

6.3. Input/Output of Timing Signals

6.3.1. Input of Timing Signals

It is not possible to synchronize the camera from an external sync source except by an extern

trigger pulse. The camera will always run with its internal X-tal controlled timing.

Trigger input through Camera Link.

Trigger input as TTL on pin #10 on 12 pin Hirose.

The trigger polarity is active low.

TI=0

TI=1

TP=0

TP=1

Trigger input can be changed to active high.

6.3.2. Output of Timing Signals

To synchronize the video data transfer from the camera the following signals are available in a

base configuration of Camera Link:

FVAL

LVAL

PCLK

DVAL

EEN

Frame valid

Line valid

Pixel clock

Data valid

High for valid Frame

High for valid line

Rising for data stobe

High for valid data

Exposure enable

Low during exposure. (Not specified by CL).

See the full connector pin assignment for Camera Link in chapter 5.3 and 5.4.5

For complete documentation on the Camera Link standard, please contact your JAI distributor.

EEN is also found as a TTL signal on pin #9 on the 12 pin Hirose. EEN is low during exposure.

6.4. Trigger Modes

This camera can operate in 6 primary modes. 1 non-triggered mode and 5 external trigger

modes, which can be set by RS-232C commands.

Normal continuous Mode. TR=0

Edge Pre-select Mode. TR=1

Restart Continuous Trigger Mode. TR=2

Pulse Width Control Mode. TR=3

Burst Trigger mode Mode. TR=4

PIV Mode. TR=5

Pre-selected exposure. (SM=0, SM=1)

Pulse width controlled exposure.

5 EPS. Read out by trailing trig. edge.

In normal continuous mode and edge pre-select mode the shutter time can be selected from the

normal 10 fixed steps. (SM=0). Or it can be selected from the 1216 steps programmable (SM=1).

Pulse width control can be used for long time exposure. The trigger pulse width can be from 2

LVAL to ∞. The exposure time is not recommended to exceed 2 seconds.

Partial scan (SC=0 through 3) can be used in all 6 modes.

Important note on changing trigger modes by RS-232C and CL.

Disconnect or stop the trigger input before changing mode by RS-232C or Camera Link. In worst

case it can lead to latch-up of camera function and communication if a mode command is

received at same time as a trigger pulse. The modes are trigger modes (TR) and scanning (SC).

The camera latch-up can only be reset if the power is switched off and on again.

6.4.1. Continuous Operation (Non triggered)

Mode settings can be done with RS-232C. Trigger Mode Normal. TR=0. It is for applications where

the camera is continuously running without external trigger. The shutter mode can be normal or

programmable exposure. (SM=0, SM=1). The shutter will work in all 10 steps up to 1/14,000

second or with the programmable exposure in 1216 steps. In partial scanning, shutter times

longer than the actual frame time has no meaning. The exposure will be equal the frame time.

In this mode it is possible to have CCIR/EIA composite analogue video output for monitor use. It

is for full scan only. The video can be 50 or 60 frames per second with a line frequency at 15.734

kHz. CCIR has 290 active lines. Shutter speed <313 LVAL. EIA has 240 active lines. Shutter speed

<263 LVAL.

6.4.2. Edge Pre-select Mode

In EPS mode, the trigger leading edge will start an exposure at the first LVAL pulse if LS=0, (or

immediately if LS=1), and it stops and the resulting image is read out after the pre-selected

shutter time. It can be the 10 steps in normal or 1216 steps in programmable. SM=0 or SM=1.

This mode will operate with full and partial scanning.

An EEN pulse will indicate the active accumulation time, and a FVAL pulse indicates that the

resulting video is read out.

To use this mode:

Important notes on using this mode.

•

The duration of the trigger should be >2LVAL to <3FVAL.

If LS=0 (Synchronous accumulation), the minimum trigger interval is 1 FVAL + 3 LVAL. The

new exposure should not be finish before the previous frame is read out.

If LS=1 (Asynchronous accumulation) the minimum trigger interval is the exposure time +

3 LVAL. A new trigger must not be applied before FVAL is low.

6.4.3. Restart Continuous Trigger mode

The RCT mode is in principle the same as normal continuous mode. The difference is that an

external trigger pulse will immediately stop the video read out and reset and restart the vertical

timing. After a fast dump read out, a new triggered exposure is started and read out as normal.

The fast dump read out is performed with a speed 18 times faster for single output, and 10 times

faster for dual output. If no further trigger pulses are applied, the camera will continue in

normal mode. This fast dump read out has the same effect as “smearless read out”. Smear over

highlighted areas are reduced for the triggered frame.

The restart continuous trigger mode makes it possible to use a lens with video controlled iris in

intelligent traffic surveillance applications.

To use this mode:

6.4.4. Pulse Width Control Mode

In PWC mode, the trigger leading edge will start an exposure at the first LVAL pulse if LS=0 (or

immediately if LS=1). It stops at the trailing edge of the trigger pulse, and the resulting video is

read out. This mode will operate with full and partial scanning. An EEN pulse will indicate the

active accumulation time, and a FVAL pulse indicates that the resulting video is read out.

Long time exposure can be done with pulse width control mode.

Important notes on using this mode.

•

The duration of the trigger can be >2LVAL to ∞. Thermal noise and dark current noise will

increase by accumulation time, therefore the exposure time is not recommended to

exceed 2 seconds.

•

If LS=0 (Synchronous accumulation), the minimum trigger interval is 1 FVAL + 3 LVAL. The

new exposure should not be finished before the previous frame is read out.

If LS=1 (Asynchronous accumulation) the minimum trigger interval is the exposure time +

3 LVAL. A new trigger must not be applied before FVAL is low.

6.4.5. Burst Trigger mode

With the burst trigger function, a single trigger pulse can start a sequence with five previous set

pre-selected programmable exposures. The five shutter times can be set with BSH1 through

BSH5. (Exposure 1H through 1216H.) The exposure is LVAL synchronous.

The sequence will start with the first exposure at the first LVAL pulse after the trigger leading

edge, and the result is read out after the selected shutter time. During the read out of the

previous frame, the next exposure starts. It will continue until exposure 5 is read out.

This mode will operate with full and partial scanning.

An EEN pulse will indicate the active accumulation time, and a FVAL pulse indicates that the

resulting video sequence is read out.

6.4.6. PIV mode.

PIV mode (Particle Image Velocimetry) can be used in applications where 2 images should be

taken with a very short time interval. It can only be used with strobe flash as illumination. The

first accumulation time is fixed at 4 µsec. After a delay >1.5 µsec. the second exposure period

starts. It is as long as the time for a full frame. The accumulation is LVAL a-synchronous. The

first exposure period starts at the trigger leading edge. The first strobe flash should be fired

within the first exposure period, and the second strobe flash during the first frame read out

period. The result will then be 2 frames exposed with the flash interval.

7.6. Camera Control Tool for CV-M2

From www.jai.com Camera Control Tool for Windows 98/NT/2000 can be downloaded.

The control tool contents a camera control program and tools for making your own program.

For the integrator and experienced user, the Camera Control Toll is much more than a program

with a window interface. It also provides an easy and efficient ActiveX interface built for MS

Windows 98, ME, NT and 2000. The OCX interface has the ability to connect to the camera using

the serial interface of the PC by reading and writing properties for the camera. This integration

requires simple programming skills within Visual Basic, Visual C++ or similar languages in a

Microsoft Windows environment. Below the different windows are shown.

10. Appendix

Precautions

Personnel not trained in dealing with similar electronic devices should not service this camera.

The camera contains components sensitive to electrostatic discharge. The handling of these

devices should follow the requirements of electrostatic sensitive components.

Do not attempt to disassemble this camera.

Do not expose this camera to rain or moisture.

Do not face this camera towards the sun, extreme bright light or light reflecting objects.

When this camera is not in use, put the supplied lens cap on the lens mount.

Handle this camera with the maximum care.

Operate this camera only from the type of power source indicated on the camera.

Power off the camera during any modification such as changes of jumper and switch setting.

Typical CCD Characteristics

The following effects may be observed on the video monitor screen. They do not indicate any

fault of the CCD camera, but do associate with typical CCD characteristics.

V. Smear

Due to an excessive bright object such as electric lighting, sun or strong reflection, vertical

smear may be visible on the video monitor screen. This phenomenon is related to the

characteristics of the Interline Transfer System employed in the CCD.

V. Aliasing

When the CCD camera captures stripes, straight lines or similar sharp patterns, jagged image on

the monitor may appear.

Blemishes

Some pixel defects can occur, but this does not have en effect on the practical operation.

Patterned Noise

When the CCD camera captures a dark object at high temperature or is used for long time

integration, fixed pattern noise (shown as white dots) may appear on the video monitor screen.
