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.
Applications
Performance and reliability of this camera make it well suited for the most demanding
applications as film and document scanning, semiconductor and PCB inspection,
DNA analysis, metrology, X-ray imaging.

Getting Started
1. Connect the camera to one of the computer serial ports (COM1 or COM2) by
using the RS-232 cable.
2. Power on the camera.
3. Install "COMMCAM" software in your computer (refer to the "COMMCAM User
Guide").
4. Install FGT COLOR frame grabber board and FGT software in your computer
(refer to the "FGT Frame Grabber User Guide").
5. Run the system.

Imaging System
Description
Figure 1. Imaging System
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 integration time in order to have incident
lighting on the CCD. The user must design an electro-optical interface to drive the cam-
era, 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.

CCD Description
·
Image format: 28.7 mm (V) x 28.7 mm (H)
·
2048 mm (V) x 2048 mm (H) active pixels
·
Pixel Geometry: 14 µm (V) x 14 µm (H)
·
Filter Mosaic (Bayer Pattern):
Note:
First active pixel of first active line is blue.
·
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 delivers black and white video.
·
Data rate is (pixel clock): 20 MHz.
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 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.
Figure 3. External Trigger Timing Diagram
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.
