Product Description
This camera is designed to meet high performance and quality requirements while
providing ease of use.
• Atmel manages the entire manufacturing process, from the sensor to the camera.
The result is a camera that operates in 12 bit s, with dedicated electronics that
provide 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.

Camera
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
must be used in front of the camera during the integration time in order to obtain 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.

• Antiblooming by clocking.
Timing • 2 x 2 and 4 x 4 pixel binning can be used to enable previewing modes.
• When binning is used, the camera deliv ers black and white video.
• The data rate is (pixel clock): 20 MHz.

Mode Frame Readout Time
No binning 235 ms
2 x 2 pixel binning 125 ms

Three timing modes are available:
• Continuous
• External triggered
• Integration time controlled (ITC)
Continuous Timing Mode 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 the RS-232 interface.

External Trigger Timing Mode The external TRIG signal gives the user control over 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 the RS-232 interface.
• 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 enables the user to fully control the 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 g r eater t han t he su m of t he 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. This mode is recommended if
• Antiblooming ON: antiblooming activated.
