JPEG compression
The 4-camera firmware variant of the Coaxlink Quad CXP-12 JPEG implements four independent image acquisition channels with, for each of them, a Bayer CFA decoder and a baseline JPEG encoder that can process up to 250 Megapixels/s, for a total of 1 billion color pixels per second.
Each channel delivers two concurrent streams: a “JPEG” encoded stream for recording and a “Preview” stream for monitoring.
The JPEG stream delivers, with a typical latency of only 20 lines, 4:2:2 full-resolution JFIF-compliant encoded images compatible with standard JPEG decoders. The JPEG encoding quality is configurable from 1 to 100.
The Preview stream provides 8-bit Bayer full-resolution, 24-bit RGB full-resolution or 24-bit RGB low-resolution images.
