Title

Compression of RAW image

Abstract
The invention relates to a raw image encoder for encoding a raw image of a predetermined color pattern according to which the raw image is partitioned into pixel cell blocks, each pixel cell block comprising four pixels, each pixel being associated with one of three base colors so that each pixel cell block comprises, for each of the three base colors, at least one pixel, the raw image encoder configured to subject the raw image to a color transformation to obtain a color image, by mapping, for each pixel cell block, the four pixels of the pixel cell block onto a color component quadruple forming a sample of the color image, the color component quadruple comprising three color component values of a target color space, and one pseudo color component value, and subject the color image to a multi-component picture encoding to obtain a compressed data stream.
