3.5.7.1 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 Qvideophone. The CAMIF delivers the raw 10-bit
Bayer pattern data (preferred) to the video front-end (VFE) that performs the required image processing (RGB-triplet gen-
eration, 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.
