CAMELIACOL 8M 8 Megapixels Digital Color Camera
Product Description
This camera is designed to meet high performance and quality requirements while providing easiness of use. · ATMEL manages the whole chain, from the sensor to the camera. The result is a camera able to work in 12-bit, with a dedicated electronic offering an excellent signal to noise ratio. The programmable settings let the user works at different integration time and gain. External trigger allows to synchronise the camera on external event while hardware white balance adjustment avoids subsequent software processing.

Power Supply Cable +24V
CAMELIA camera is powered by a single +24V power supply. CAMELIA camera is configurable via the serial port of the computer (by using either CommCam software or standard RS232 communicator as TTY or Hyperterminal). CAMELIA camera sends digital video. As CAMELIA's CCD is a full frame sensor, the user 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. The user 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. The BG38 Filter is essential to have a correct white balance on Color Cameras. Note that the following Elements are not provided by ATMEL: · · · · · · · Shutter (LCD or Mechanical) BG38 (Anti Infra Red) Filter Control Box Lens Light Source +24V Power Supply Computer
For a complete explanation of the utility of the BG38 Filter and the Shutter, please consult the associated FAQs and the example Images on the ATMEL CDROM "Camera Documentation & Software".

Anti-blooming by Clocking
Anti-blooming can be activated or inhibited (see "RS232 Controls" on page 11): · · · Anti-blooming OFF: anti-blooming inhibited. This position is recommended if antiblooming is not required for the application. Anti-blooming ON: anti-blooming activated. When binning is disabled, the anti-blooming is efficient until 8 times the saturation Current.

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. Figure 3. Video Signal Processing Gain

Timing
2x2 and 4x4 pixel binning are possible to enable previewing modes. Preview mode is only available in Black and white otherwise the user has to use Overlay mode (but neither correction nor software LUT are applicable on displayed images). Table 2. Timing Mode

Frame Timing
Three timing modes are available: Continuous, external triggered and Integration Time controlled (ITC). The signals described in the following drawings are: Table 3. Frame Timing

1. Pixel is defined as valid (part of the Frame) when both LEN and FEN Signals are at Low Level. 2. The latency (called Td after) of 1 Readout line Time defined below depends on the binning mode. For no binning, this precision is around 104 µs. 3. Minimum Time at high level of LEN Signal is 10 µs (Transfer Time between two lines). 4. Minimum Time at high level of FEN Signal is 4 lines readout Time (around 416 µs). 5. Shutter Delay is adjustable via Commcam or RS232 commands (1, 5, 10 or 20 ms).
