♦ 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.

2.1 CCD
♦ image format : 35.9mm(V) x 26.5mm(H)
♦ 1840(V) x 1360(H) active pixels
♦ readout register along the small side of the image area. (vertical image)
♦ pixel geometries :
◊ 19.5µm(V) x 19.5µm(H).
♦ filter mosaic : BAYER pattern :

◊ note : first active pixel of first active line : blue.
♦ anti-blooming by clocking.
2.2 TIMING
3 timing modes are available :
♦ continuous : the camera delivers frames continuously :
◊ frame N+1 integration starts as soon as frame N readout is completed.
◊ integration time is set by RS232
♦ operation with external trigger : integration start is controlled by the user from the external signal TRIG :
◊ the rising edge of TRIG activates the start of the frame integration. This rising edge is synchronized by
the camera with a precision of 200µs
◊ integration time is set by RS232
◊ note : TRIG signal period must be greater than integration time plus frame readout time.
♦ operation with “ integration time control ” : integration is fully controlled by the user from the external signal ITC :
◊ the falling edge of ITC activates the start of the frame integration. This falling edge is synchronized by the
camera with a precision of 200µs
◊ the rising edge of ITC activates the stop of the frame integration. This rising edge is synchronized by the
camera with a precision of 200µs
◊ note : ITC signal period must be greater than integration time (defined by ITC low) plus frame readout
time.
2x2 and 4x4 pixel binning is possible to enable previewing modes.When binning is used, the camera delivers black and white video.

2.3 ANTI-BLOOMING BY CLOCKING
Anti-blooming can be activated or inhibited (see 2.5.3) :
♦ anti-blooming OFF : this position is recommended if anti-blooming is not required for the application.
♦ anti-blooming ON : anti-blooming operation reduces the pixel saturation charge. As a consequence, camera
gain must be set to 1.30x (see 2.5.3) minimum in order to reach the camera saturation level (4095 adu)

operation with “ integration time control ” :
TRIG_ITC = ITC
TRIG_ITC is synchronized by the camera line clock (jitter : 200 µs)

Note : video signal processing gain of the camera can be adjusted by setting :
♦ either ‘’CDS gain’’ : a commutation 1x or 4x is available at the input of the video signal processing. Use of the 4x
position is recommended for low level applications (noise is lower)
♦ or ‘’camera gain’’ : a range of 1x to 2x is available in 16 steps.
