6. Functions and Operations
In the following the format shown in “7.3. CV-A33CL command list” are used for function
commands and parameters.
6.1. Basic functions
The CV-A33CL camera is a progressive scan camera with 10 or 8 bit video output in single
channel Camera Link.
Programmable partial scan, where the start line and the number of lines can be selected with 1
line increment is also available.
There are 4 modes: Normal continuous, and 3 trigger modes: Edge Pre-Select (EPS), Pulse Width
Control (PWC) and Auto Trigger.
The accumulation is LVAL a-synchronous.
In the following some of the functions are shown in details.
6.1.1. CMOS Sensor
The CMOS sensor principle layout is shown.
The sensor is an array of active photosensitive
pixels. The global shutter is working
simultaneously on all pixels. The readout can be
random row by row. 4 columns are feed through

a 4 to 1 multiplexer to an A/D converter. The
digitized row signals are placed in a vertical
D
register by a 1 to 4 multiplexing. From here it is
read out with the pixel clock pulses, even if the
window of interest has fewer columns. The

described. The photo diode and charge capacitor is
reset when switch 1 is closed. The signal accumulation
starts when sw 1 open. The charge is transferred to the
pixel memory capacitor when sw 2 close. The
accumulation stop when sw 2 open, and the signal is
now temporary stored in the memory capacitor. After
reset of the charge capacitor, a new accumulation can
start. The signal on the pixel memory capacitor is read
out to the column by the read row signal. The memory
can now be reset.

6.1.3. Column Process
The voltage signal from a single pixel is send to the
column amplifier trough the 4 to 1 multiplexer. After
the S/H circuit, the offset and gain calibrating is
perform. A 10 bit A/D converter send the digital pixel
signal to the digital horizontal shift register by a 1 to 4
multiplexing. Signals from a single row with 667 pixels
are processed in parallel and send to the shift register.
Control and timing is done from the timing block.

If a higher frame rate is wanted, it is possible to change
the CMOS sensors sensing area to the window of
interest. WS =1 for windows scan.
The X,Y start coordinate, the window width and height
can be programmed.

WH can be in the range 3 to 493. (WY + WH ≤ 493)
The frame rate will not increase if the width WW is
reduced. The horizontal shift register need to be read
out in its full length.
LVAL
DVAL
Minimum size for the window of interest is 2 (h) x 3 (v)
pixels.
Maxim frame rate is 4953 fps.
For DVAL timing details for the window of interest,
refer to 6.2.5 fig. 17 through 19.
Fig. 12. Windows of Interest
6.1.7. Auto Trigger Window of Interest.
The auto trigger function, TR=3 can be used as sensing device inside the camera field of view.
The scanned area is from top of the image, and the height can be programmed with the
command AT= --. The accumulation time is equal to the number of LVAL programmed with AT.
The minimum height of the window of interest for the auto trigger function is the 3 top lines of
the image. The height of the auto trigger window can be programmed in the range AT = 3 to
493. The window is always from the top of image. The read out time is the active number of
LVAL + 9 LVAL.
Maxim frame rate is 5403 fps given by the 11 LVAL for a minimum window read out.
(1 LVAL = 16.825 µsec.)
The connected frame grabber should be programmed to sense if objects passing the window.
The horizontal position and the signal threshold could be the programmed parameters. If an
object passing is detected, a trigger is send to the camera, and a full frame is exposed with the
same accumulation time as programmed for AT. The resulting image, a full frame or windows
scan, (depending of windows scan setting), is read out to the grabber, and the auto trigger
function will start again.

The line at the end of the exposure period (SM=0, SM=1) will have a slightly lower signal
level. (About 10%). It is caused by the CMOS. (With SH=1/250 the line is seen in the
middle of the image).
For timing refer to 6.2.2. and 6.2.3. Fig. 14. and fig 15.
For windows scan timing refer to 6.2.5 and fig.17 through fig.19.
6.4.2. Edge Pre-select Mode
The exposure will start 28 µsec. after the trigger leading edge, and it stops and is read out after
the shutter time selected. It can be the 8 steps in normal or 2 to 493 steps in programmable.
SM=0 or SM=1. In programmable exposure the actual exposure is 1 LVAL less than the PE value.
This mode will operate with full window or windows of interest 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:
Set function:
Trigger mode “Edge Pre-select”
Shutter mode “Normal” or “Programmable”

6.4.4. Auto trigger Mode
The auto trigger function, TR=3 can be used as sensing device inside the camera field of view. It
sense in a programmable window from top of the image. The continuous output is sent to the
frame grabber, which PC should be programmed to sense if an object is passing the window. The
horizontal position and the signal threshold could be the programmed parameters. If an object
passing is detected, a trigger is send to the camera. The resulting image, a full frame or
windows scan, (depending of windows scan setting), is read out to the grabber, and the auto
trigger function with fast scan of the programmed window will start again.

7.4. Camera Control Tool for CV-A33
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.
