1. IMAGING SYSTEM DESCRIPTION

♦ CAMELIA camera is powered by a +24V power supply.
♦ CAMELIA camera is configured through the serial port of the computer.
♦ CAMELIA camera sends digital video to the FGT frame grabber.
♦ As CAMELIA 's CCD is a full frame sensor, you must use either pulsed lightning or a chopper/shutter in front of

the camera in order to have incident lightning on the CCD only during integration time. You must design an
electro-optical interface to drive camera, shutter/chopper or lightning by using the "SHUTTER" signal delivered
by the camera. If required, the system can send an external trigger or external ITC (integration time control
signal) to the camera.

3.3 ANTI-BLOOMING BY CLOCKING

Anti-blooming can be activated or inhibited (see RS232 control):

◊ Anti-blooming OFF : anti-blooming inhibited. This position is recommended if anti-blooming is not required

for the application.

◊ Anti-blooming ON : anti-blooming activated.

3.4 VIDEO SIGNAL PROCESSING GAIN

Video signal processing gain can be adjusted by setting the ''CDS gain'' via RS232 : a commutation 1x or 4x is
available at the input of the video signal processing. The 4x position is recommended for low level applications
(noise is lower).

4. R.O.IS (REGIONS OF INTEREST).

CAMELIA 8M can operate in a “multi ROI” mode allowing masking of regions of the image and thus increasing frame
rate by a reduced readout time.

User defines up to 5 windows to be masked. In addition he specifies starting and ending addresses for each window.
Time reduction : about 92 µsec per masked line.
Two steps :

• Enter the number of regions masked by the CommCam command : F=X (X=0 to 5)

• Enter the list of starting and ending addresses by the CommCam command : Y=ssss/eeee/ssss/eeee/…/eeee/

For example : how to mask 2 regions of 500 lines each, one on the top of image, the second on the bottom, 1x1 pixel
binning :

CommCam commands : F=2 then Y=0/500/3000/3500/

In this example readout time will be reduced of 1000 lines equivalent to 92 msec.

5. ENVIRONMENTAL REQUIREMENTS

♦ Operating temperature : 0°C / +50°C
♦ Storage temperature : -20°C / 70°C
♦ Operating humidity : < 80% at +35°C
♦ Vibration : 2g sinusoidal, from 10Hz to 100Hz.
