Abstract
Image element values are determined from a compressed block of image data relating to a reference channel and non-reference channels. Compressed channel data is used to determine an initial data value relating to a channel. A decompressed data value is determined for the non-reference channels by: (i) reading an indication of a compression mode, the compression mode being either a channel decorrelating mode or a non-channel decorrelating mode, (ii) if the compression mode is non-channel decorrelating mode, determining the decompressed data value for the non-reference channel to be the determined initial data value relating to the non-reference channel for the image element value; (iii) if the compression mode is a channel decorrelating mode, determining the decompressed data value for the non-reference channel to be a function of the determined initial data value relating to the non-reference channel and the determined initial data value relating to one of the reference channels.
