Abstract
A computer-implemented method and a decompression unit for decompressing a compressed block of data in accordance with a multi-level difference table. The compressed block of data represents a block of image data comprising a plurality of image element values, wherein each level of the multi-level difference table comprises a plurality of entries. An origin value for the block of image data is determined using data representing the origin value from the compressed block of data. A level within the multi-level difference table for the block of image data is identified using an indication of the level from the compressed block of data. For each image element value in the block of image data, a respective entry indication from the compressed block of data is used to identify one of the entries at the identified level within the multi-level difference table, and the image element value is determined using: (i) the determined origin value for the block of image data, and (ii) the identified entry at the identified level within the multi-level difference table for the image element value.
