ABSTRACT:
A compression and decompression apparatus, method and computer program product, wherein compression and decompression of image data is performed via a combination of two-dimensional reversible wavelet transform processing, context model processing, and binary entropy encode/decode processing. Faster processing, as compared to conventional devices and methods, is achieved by performing the context model processing and the binary entropy encoding/decoding processing in parallel, such that two-story pipeline processing is performed, resulting in a reduction of a basic cycle time.
