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.
