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.
