The Colibri modules have a quick capture camera interface (CIF, QCIF), which allows directly to connect a camera chip or a video ADC with the Colibri.
A typical camera sensor uses two interfaces
Sensor parameters need to be configured through I2C (resolution, exposure time, and more).
The real pixel data are then clocked to the CIF under the sensor's control. The Colibri module needs to be setup correctly in order to receive (and transform) the data.
In order to minimize CPU load, Toradex recommends to use a camera which generates an output that can be shown directly on the display without any color transformations or resizing.
Toradex can provide a software libraries including source code to make it easier to use the Quick Capture Interface. See Colibri Windows CE Features.
Colibri PXA270 26MHz
Colibri PXA320 48MHz
Colibri PXA310 96MHz
Colibri PXA300 48MHz
Keep in mind that the maximum usable bandwidth is also depending on other factors like memory bus load.
More information can be found in the PXA Datasheet, available in the respective product page.
You can find a connector for the camera interface on the Colibri Evaluation Board on "X22 CIF".
