Abstract
Compressed image data is received in substantially in raster scan order, and for each group of pixels in a row of the compressed image data, a block-based decoding scheme for the group of pixels is identified and the compressed data corresponding to the group of pixels is decoded at decoding hardware using the identified scheme.
Claims20
A method of data decompression comprising:
- receiving compressed image data substantially in raster scan order;
- and
- for each group of pixels in a row of the compressed image data, identifying a block-based decoding scheme for the group of pixels and decoding the compressed data corresponding to the group of pixels at decoding hardware using the identified scheme.
Data decompression hardware comprising:
- an input for receiving compressed image data substantially in raster scan order;
- and
- control hardware or decoding hardware arranged, for each group of pixels in the row, to identify a block-based decoding scheme for the group of pixels;
- wherein the decoding hardware is arranged, for each group of pixels, to decode compressed data corresponding to the group of pixels using the identified scheme.
