3.1.7.1 Camera interface and video front-end

The camera interface (CAMIF) connects the QSC62x0 device directly to a camera sensor. Typical applications include Qcamera, Qcamcorder, and QvideophoneThe CAMIF delivers the raw 10-bit Bayer pattern data (preferred) to the video front-end (VFE) that performs the required image processing (RGB-triplet generation, color-space conversion, auto-white balance, auto exposure, gamma correction, etc.) and prepares the image for capture or transmission. The QSC device also supports a YUV 4:2:2 input from the sensor

(8-bit, 2:1 MUX YUV or CCIR656 YUV).

The video capabilities of the two QSC devices varies slightly, with the QSC6270 providing higher performance than the QSC6270 device — greater resolution, higher capture and streaming rates, etc.
