IMAGING SYSTEM DESCRIPTION POWER RS232 FRAME DATA & SYNC GRABBER ELECTRO-OPTICAL INTERFACE TRIG_ITC 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. 3/14 CAMELIA 4M user guide 2. CAMELIA 4M CAMERA 2.1 CCD image format : 28.7mm(V) x 28.7mm(H) 2048(V) x 2048(H) active pixels readout register along the small side of the image area. (vertical image) pixel geometries : 14m(V) x 14m(H). aperture ratio : 100%. anti-blooming by clocking. 2.2 T IMING 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 112s 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 112s the rising edge of ITC activates the stop of the frame integration. This rising edge is synchronized by the camera with a precision of 112s 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. Data rate is : pixel clock : 20 MHz frame readout time : 4/14 normal mode : 235ms 2x2 pixel binning : 125ms. 4x4 pixel binning : 70ms.

This position is recommended if anti-blooming is not required for the application. anti-blooming ON : anti-blooming activated. 2.4 COLOR OPERATION In `'3 shot color'' mode, each image is made of 3 frames : red, green, blue : the camera must be operated either in `'external trigger'' mode or in `'integration time control'' mode. for each image, the user selects the color of the next frame by setting COLOUR_I1 and COLOUR_I2 input signals. COLOUR_I1, _I2 must be valid in the time period between TRIG signal rising edge (or ITC signal falling edge) and SHUTTER signal falling edge. (see timing there after) color definition is : COLOUR_I2 0 0 1 COLOUR_I1 0 1 0 Frame Color Red Green Blue integration time can be adjusted differently for each color. This allows to have a better signal to noise ratio for the colour with the lowest sensitivity (i.e the blue) each frame requires a TRIG_ITC signal. CAMELIA 4M camera synchronizes COLOUR_I1, _I2 with the rest of the timing and sends COLOUR_O1, _O2 to FGT frame grabber.
