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 works in 12 bits, with dedicated electronics
that provide an excellent signal to noise ratio.

• The sensitivity of the camera is fairly high even in the near infrared spectrum
thanks to the 100% aperture pixel.

• The programmable settings let the user work at different integration times and
gains. The external trigger enables synchronization of the camera on an external
event, while the 3-shot color mode allows very high resolution for color image
acquisition.

Applications

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

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 the 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.

CCD Description • Image format: 28.7 mm (V) x 28.7 mm (H)

• 2048 mm (V) x 2048 mm (H) active pixels

• Readout register along the small side of the image area (vertical image)

• Pixel geometry:
– 14 µm (V) x 14 µm (H)
– 100% aperture ratio

• Antiblooming by clocking

Timing 2 x 2 and 4 x 4 pixel binning can be used to enable previewing modes.

Data rate (pixel clock): 20 MHz

Table 1. Frame Readout Times

Mode Frame Readout Times

No binning 235 ms
2 x 2 pixel binning 125 ms
4 x 4 pixel binning 70 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.

• The integration time is set by the RS-232 interface.

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.

• The 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.

The external ITC signal allows 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.

3-Shot Color Modes In 3-shot color mode, each image is made of three frames: red, green and blue.

• The camera must be operated in either external trigger mode or integration time
control mode.

• For each image, the user selects the color of the next frame by setting the input
signals COLOUR_I1 and COLOUR_I2 (see Table 2). COLOUR_I1, _I2 must be
valid between the rising edge of the TRIG signal (or the falling edge of the ITC
signal) and the falling edge of the SHUTTER signal (see Figure 5).

Table 2. Color definition

COLOUR_I2 COLOUR_I1 Frame Color

00Red
0 1 Green
10Blue

• The integration time can be adjusted differently for each color, resulting in a better
signal to noise ratio for the color with the lowest sensitivity (i.e the blue).

• Each frame requires a TRIG_ITC signal.

• The camera synchronizes COLOUR_I1, _I2 with the rest of the timing and sends
COLOUR_O1, _O2 to the FGT frame g rabber.
