Patent ID: 7822281

Claim:
A method of compressing a current image of a sequence of images in a computer apparatus by a processor, said method comprising the steps of: (a) transforming the current image with a predetermined transform to provide a set of transform coefficients by the processor; (b) dividing the set of transform coefficients into a plurality of blocks, by the processor; (c) encoding a block of the plurality of blocks in a series of coding passes, the encoding including: (i) comparing the block being encoded with a corresponding block of a previously encoded image in the sequence, by the processor; (ii) determining if the block being encoded is a static block based on a result of the comparing of the block with the corresponding block, by the processor; and (iii) terminating encoding of the block at a truncation point of the corresponding block of the previously encoded image in the sequence only if the block is a static block.
