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

Perfor mance and reliabil ity of th is camer a make it wel l suited for the most dem andin g

applica tions as film and do cument sc anning, sem iconductor a nd PCB inspection,

DNA analysis, metrology, X-ray imaging.

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 mus t de si gn a n el ectr o-optical int er fac e to dr ive th e c am-

era, shut ter/choppe r or lighting by using the SHUT TER signal deli vered by the c amera.

If required, the system can send an external trigger or external ITC (integration time

control) signal to the camera.

Camelia Color 4M 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 ra te is (pix el cl ock) : 20 MH z.

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.

Figure 4. Integration Time Control Timing Diagram

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.
