3.3.2 Image Sensor (ISC) Interface

This section describes the signals and connectors related to the ISC interface.

The Image Sensor Controller (ISC) system manages incoming data from a parallel or serial CSI-2 based CMOS/CCD sensor. The system supports a single active interface, as well as the ITU-R BT 656/1120 422 protocol with an 8-bit or 10-bit data width and raw Bayer format. The internal image processor includes adjustable white balance, color filter array interpolation, color correction, gamma correction, 12-bit to 10-bit compression, programmable color space conversion, as well as horizontal and vertical chrominance subsampling module.
