Camera interface
The CAMIF (Camera Interface) within the S3C2443X consists of eight parts: pattern
mux, capturing unit, MSDMA (Memory Scaling DMA), preview scaler, codec scaler,
preview DMA, codec DMA, and SFR. The camera interface supports:
mux, capturing unit, MSDMA (Memory Scaling DMA), preview scaler, codec scaler,
preview DMA, codec DMA, and SFR. The camera interface supports:
ITU R BT-601/656 YCbCr 8-bit standard and Memory
Maximum input size of 4096x4096 pixels (2048x2048 pixels for scaling)
Two scalers:
One is the preview scaler, which is dedicated to generating smaller size images for
previewing. The other one is the codec scaler, which is dedicated to generating codec
useful images like plane type YCbCr 4:2:0 or 4:2:2. Two master DMAs can do mirror
and rotate of the captured image for mobile environments. And test pattern
generation can be used to calibration of input sync signals as HREF, VSYNC. Also,
video sync signals and pixel clock polarity can be inverted in the camera interface
side with using register setting.
