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.

2. CAMELIA 8M CAMERA

2.1 CCD

♦ image format : 35.0mm(V) x 23.0mm(H)
♦ active pixels :

Mode (set via RS232) Image size (H x V)

No binning 2300 x 3500
2x2 pixel binning 1150 x 1750
4x4 pixel binning 574 x 875

♦ readout register along the small side of the image area. (vertical image)
♦ pixel geometry :

◊ 10µm(V) x 10µm(H).
◊ aperture ratio : 100%.

♦ anti-blooming by clocking.

2.2 TIMING MODES

3 timing modes are available (set via RS232) :

♦ 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 110µs

◊ 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 110µs

◊ the rising edge of ITC activates the stop of the frame integration. This rising edge is synchronized by the

camera with a precision of 110µs

◊ 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 : 25 MHz
♦ frame readout time :

◊ normal mode : 370ms
◊ 2x2 pixel binning : 200ms.
◊ 4x4 pixel binning : 110ms.

2.4 ANTI-BLOOMING BY CLOCKING

Anti-blooming can be activated or inhibited (set via RS232) :

◊ anti-blooming OFF : this position is recommended if anti-blooming is not required for the application.
◊ anti-blooming ON : anti-blooming is activated.

CAMELIA 8M user guide

2.5 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 COLOUR_I1 Frame Color

0 0 Red
0 1 Green
1 0 Blue

◊ integration time can be adjusted differently for each color (set via RS232). This allows to have a better

signal to noise ratio for the color with the lowest sensitivity (i.e. the blue)

◊ each frame requires a TRIG_ITC signal.
◊ CAMELIA 8M camera synchronizes COLOUR_I1, _I2 with the rest of the timing and sends COLOUR_O1,

_O2 to FGT frame grabber.

2.6 ROIS

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.
