4.6.4 Interfacing with an Image Sensor Controller (ISC)

The Image Sensor Controller (ISC) system manages incoming data from a parallel sensor. It supports a single active interface. The parallel interface protocol can use a free-running clock or a gated clock strategy. It supports the ITU-R BT 656/1120 422 protocol with a data width of 8 bits or 10 bits 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 and horizontal and vertical chrominance subsampling module. The module also integrates a triple channel Direct Memory Access Controller host interface.
