20.5 Data format description
20.5.1 Data formats
Three types of data are supported:
8-bit progressive video: either monochrome or raw Bayer format
●
YCbCr 4:2:2 progressive video
●
RGB565 progressive video. A pixel coded in 16 bits (5 bits for blue, 5 bits for red, 6 bits
●
for green) takes two clock cycles to be transferred.
Compressed data: JPEG
For B&W, YCbCr or RGB data, the maximum input size is 2048 × 2048 pixels. No limit in
JPEG compressed mode.
For monochrome, RGB & YCbCr, the frame buffer is stored in raster mode. 32-bit words are
used. Only the little endian format is supported.
