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.

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.

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.

Note: 1. The camera’s video signal processing gain can be adjusted by setting either the CDS

or camera gain.
CDS gain: a 1x or 4x gain is available at the input of the video signal processing. Use

of the 4x gain is recommended for low level applications as it results in lower noise.
Camera gain: a range of 1x to 2x is available in 16 steps.

Value must be in milliseconds
Range: 1 to 2000 ms

Must be an integer (e.g. 120 for
120 ms, 120.4 is not permitted)

Operating conditions • Room temperature: 20°C

• Integration time in darkness: 100 ms

• Light source: Halogen 3200K with BG38 (2 mm thick) IR cut-off with f/4 aperture

• Defective pixels will be detected separately for each color and with respect to the
mean value of each color

(See Table 6 on page 10 for amplitude or d eviation with respect t o the mea n value). The
number and size of blemishes are computed by taking into account all the pixels of the
frame.

Definitions A column defect is a one-pixel-wide column with more than 20 defective pixels. The col-

umn's height is constant with the light level.
ADU: 12 bits correspond to 4096 ADUs.
α is the contrast of the defect measured as a percentage under light and in ADU in

darkness.

Specification Under
Illumination

The test is carried out under illumination so that the most sensitive channel is at 80% of
the saturation level.

Blemishes are tested under white light and column defects are tested under green light
(P20).

Notes: 1. A maximum of 100 blemishes with an area between 1 x 1 and 2 x 2 is accepted but

the total number of pixels affected by blemishes is below 140.

2. Inside an area of 3 x 3 pixels, there is a maximum of 5 defective pixels.
