Product Description

As part of AViiVA family, this is designed with three concepts in mind: accuracy, versa-
tility and easy implementation:
·

A very compact mechanical design incorporates a 4k color linear sensor.

Atmel manages the whole chain, from the sensor to the camera. The result is a
camera able to work in 8- or 12-bit, with dedicated electronics offering an
excellent signal to noise ratio.

The programmable settings let the user work at different integration time, gain and
offset. External clock and trigger allow the synchronization of several cameras.

Applications

Performance and reliability of this camera make it suitable for machine vision applica-
tions requiring low cost color capture i.e. print, packaging inspection or part sorting.
Using this camera avoids facing usual problems observed with tri-linear sensor on
optical alignment and object synchronization.

Color Principle

CCD Description

The color CCD sensor is based on a 2 taps, 4096 pixels linear sensor with RGB color filter. It
results 1365 RGB patterns (+1 extra red pixel).

Figure 1. Color CCD Sensor Synoptic

IR Cut-Off Filter

For calibrated color response, the AViiVA C2 sensor shall not be exposed to IR wavelength
(> 700 nm). Therefore depending of the ligth source, the user shall place or not a IR cut-off fil-
ter in front of the sensor. The AViiVA C2 sensor has been calibrated with a BG38 2 mm. The
AViiVA C2 is available with or without BG38 2 mm (refer to the ordering code).

White Balance

The white balance function is not included in the camera. It shall be done by software or hard-
ware at application level.

The color filters are balanced for a typical 5500

K light source with BG38 2 mm. For each light

source, the white balance shall be done. For example, at 3200

K with GB38 2 mm,the follow-

ing typical gains must be applied to white balance the images.

Color Space
Correction

The color space correction function is not included in the camera. It shall be done by software
or hardware at application level.

After white balance, the color space correction shall be done to improved the color response.
This correction consists in a linear operation to convert the RGB triplet form the camera color
space to the RGB triplet of the final color space. The final color space can be a monitor, a
printer or others application specific color space. For some specific applications where "abso-
lute" color value is not mandatory the color space correction can by bypassed.

At 3200K with BG38 2 mm and for a standard PC screen, this typical matrix must be applied to
correct the colors.

Camera Description

Figure 2. Camera Synoptic

The camera is based on a two-tap linear CCD. Therefore, two analog chains process odd and
even pixel outputs of the linear sensor. The CCD signal processing encompasses the corre-
lated double sampling (CDS), the dark level correction (dark pixel clamping), the gain (PGA)
and offset correction and finally the analog to digital conversion on 12-bit.

Note:

PGA stands for Programmable Gain Array.

The camera is powered by a single DC power supply from 12V to 24V.

The functional interface (data and control) is provided with the CameraLink interface. The
camera uses the base configuration of CameraLink standard.

Note:

FVAL = 0

In RGB serial mode, the data can be delivered eitheir on two channels or on a single multi-
plexed channel. The data format can be configured in 8-or 12-bit, See "Output Data Timing" on
page 9.

In RGB parallel mode, the data are provided on three channels corresponding to red, green
and blue information. The data format is only on 8-bit. In this mode two interpolation mecha-
nism can be selected, See "Output Data Timing" on page 9.

The camera can be used with external triggers (TRIG1 and TRIG2 signals) in different trigger
modes (see "Synchronization Mode" on page 7). The camera can be also clocked externally,
allowing system synchronization and/or multi-camera synchronization.

The camera configuration and settings are performed via a serial line.

This interface is used for:
·

Gain, offset setting.

Dynamic range, data rate setting, RGB mode.

Trigger mode setting: free run or external trigger modes.

Integration time setting: in free running and external trigger mode.
