3. TECHNICAL BRIEF

3.7 Camera Interface(AIT701G, U400)

This model has a built-in VGA(640 x 480) camera module. And the camera produces JPG pictures.

Camera module is controlled by AIT701G. Interface is done by I2C and YCbCr format. I2C is a control

signal and YCbCr is real data interface signal.
