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
R
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
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
frame speed depends only of the height of the
window, not of the width.
Pixel principle and column processing with A/D
converting is shown below.

6.1.2. Pixel principle
Each pixel consists of a sensing part, a pixel memory
and an amplifier. The function can in short be
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

can now be reset.
With this construction all pixels will integrate at the same time, (Global shutter). The resulting
image is temporary stored in the pixel memory during read out, while a new exposure can be
started.
All timing is set up in the timing block by an internal serial link.

CV-A33CL
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.
The calibrate command CB = 0 will start an automatic
calibrate routine for offset and gain for all 167 A/D
converter. It reduces the vertical fix pattern column noise.
6.1.4. CV-A33 CMOS Sensor array
The CMOS sensor total array is 667 (h) x 502 (v).
Here the 659 (h) x 494 (v) is active photo sensing
pixels. 8 pixels (h) and 8 rows (v) are optical
black pixels for internal black level reference.
There is an A/D converter for each 4 columns.
A 4 to 1 multiplexer feed the signals from 4
columns to a A/D converter. The digital
converter output is multiplexed to the 667 x10
bit register.

6.1.6. Window of Interest
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.
WX can be in the range 0 to 657
WY can be in the range 0 to 490
WW can be in the range 2 to 659. (WX + WW ≤ 659)
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.
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.

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.

Fig. 16. LVAL a-synchronous accumulation
In CV-A33 with LVAL a-synchronous accumulation a new trigger can be input and 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.
The minimum trigger interval should be >(1FVAL + 1 LVAL).

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. TI=0
Trigger input as TTL on pin #10 on 12 pin Hirose. TI=1
The trigger polarity is active low. TP=0
Trigger input can be changed to active high. TP=1
The trigger input on pin #10 on the 12 pin Hirose connector can be 75 Ω terminated with the
internal switch SW 300-1 ON.
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 Frame valid High for valid Frame
LVAL Line valid High for valid line
PCLK Pixel clock
DVAL Data valid High for valid data
EEN Exposure enable Low during exposure
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 4 primary modes. 1 non-triggered, 2 external asynchronous trigger
modes and auto trigger mode.
1. Normal continuous Mode. TR=0 Pre-selected exposure. (SM=0, SM=1)
2. Edge Pre-select Mode. TR=1 Pre-selected exposure. (SM=0, SM=1)
3. Pulse Width Control Mode. TR=2 Pulse width controlled exposure.
4. Auto Trigger Mode. TR=3 >3 line window, <5404 fps
In normal continuous mode (TR=0) and edge pre-select mode (TR=1) the shutter time can be
selected from the normal 8 fixed steps (SM=0), or it can be selected from the 2 to 493 steps
programmable (SM=1). In programmable exposure the actual exposure is 1 LVAL less than the PE
value.
The trigger pulse width should be >1 LVAL to <3 FVAL. (>16.8 µsec. to <25 msec.)
In pulse width control (TR=2) the trigger pulse width should be >1 LVAL to <237 FVAL. (>16.8
µsec. to <2 sec.)
Windows of interest (WS=1) can be used in normal, edge pre-select and pulse width control
mode. (TR=0, TR=1 and TR=2).
- 13 -
Page 15
CV-A33CL
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 continuous running without external trigger. The shutter mode can be normal or
programmable exposure. (SM=0, SM=1). The shutter will work in all 8 steps up to 1/20,000
second or with the programmable exposure in 2 to 493 steps. In programmable exposure the
actual exposure is 1 LVAL less than the PE value.
In windows scan (WS=1), shutter times longer than the actual frame time have no meaning. The
exposure will be equal the frame time.
To use this mode:
Set function: Trigger mode “Normal” TR=0
Shutter mode “Normal” or “Programmable” SM=0, SM=1
“Shutter Speed” SH=0 through 7
“Programmable exposure” PE=2 through 493
“Windows” “Full” or “Windows scan” WS=0, WS=1
Polarity and other functions
Important notes on using this mode.
• 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” TR=1
Shutter mode “Normal” or “Programmable” SM=0, SM=1
“Shutter Speed” SH=0 through 7
“Programmable exposure” PE=2 through 493
“Windows” “Full” or “Windows scan” WS=0, WS=1
Polarity and other functions
Input: Ext. trigger to Camera Link or pin 10 on 12-pin connector.
Important notes on using this mode.
• The duration of the trigger should be >1 LVAL to <3 FVAL. (>16.8 µsec. to <25 msec.)
• A new trigger can be applied before FVAL is low as long as the exposure will be on for
longer than the FVAL high period. Refer to 6.2.4
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.
For LVAL a-synchronous accumulation refer to 6.2.4 and fig 16.

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.
To use this mode:
Set function: Trigger mode “Auto Trigger Mode” TR=3
“Auto Trigger” AT=3 through 493
“Windows” “Full” or “windows scan” WS=0, WS=1
Polarity and other functions
PC and grabber: Detect trigger conditions
Send a pulse width control trigger to the camera.
Input: Ext. trigger to Camera Link or pin #10 on 12-pin connector.
Important notes on using this mode.
• The exposure is equal the programmable parameter AT.
• The exposure time is the same for the auto trigger partial scanned frame and the
resulting triggered frame read out.
• The duration of the trigger should be >1 LVAL to < 1 FVAL. (>16.8 µsec. to <8.3 msec.)
• Refer to 6.1.7. Auto Trigger Window of Interest.
• Max auto trigger frame rate is 5403 fps.

7.4. Camera Control Tool for CV-A33
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.
