Product Description
This camera is designed to meet high performance and quality requirements while providing ease of use. · ATMEL manages the whole process, from the sensor to the camera. The result is a camera that works in 12-bit, with dedicated electronics that provides an excellent signal to noise ratio. The programmable settings let the user work at different integration times and gains. The external trigger allows synchronization of the camera on an external event while the hardware white balance adjustment avoids subsequent software processing.

Appl ication s
Performance and reliability of this camera make it well suited for the most demanding app li ca tio ns as film and document scanning, semiconductor and PCB inspection, DNA analysis, metrology, X-ray imaging.

Power Supply Cable 24V
The Camelia 4M is powered by a 24V power supply and is configured through the serial port of the computer. The camera sends digital video to the FGT frame grabber. As Camelia's CCD is a full frame sensor, either pulsed lighting or a chopper/shutter mus t be used in front of the camera during integration time in order to have incident lighting on the CCD. The user must design an electro-optical interface to drive the camera, shutter/chopper or lighting 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.

Mode No binning 2 x 2 pixel binning 4 x 4 pixel binning Frame Readout Time 235 ms 125 ms 70 ms
Three timing modes are available: · · · Continuous Timing Mode Continuous External triggered Integration time controlled (ITC)
The camera delivers frames continuously: · · Frame N+1 integration starts as soon as frame N readout is completed (Figure 2). Integration time is set by RS-232.

External Trigger Timing Mode The external TRIG signal allows the user to control the start of frame integration: · · · The rising edge of TRIG activates the start of frame integration. This rising edge is synchronized by the camera with a precision of 112 µs. Integration time is set by RS-232. Note that the TRIG signal period must be greater than the sum of the integration time and the frame readout time.

Integration Time Control (ITC) Timing Mode
The external ITC signal allows the user to fully control frame integration: · · · The falling edge of ITC activates the start of frame integration. This falling edge is synchronized by the camera with a precision of 112 µs. The rising edge of ITC activates the stop of frame integration. This rising edge is synchronized by the camera with a precision of 112 µs. Note that the ITC signal period must be greater than the sum of the integration time (defined by ITC low) and the frame readout time.

Antiblooming by Clocking
Antiblooming can be activated or inhibited (see "RS-232 Interface" on page 7): · · Antiblooming OFF: antiblooming inhibited. Recommended if antiblooming is not required for the application. Antiblooming ON: antiblooming activated.
