Method and apparatus for accelerating image data compression

摘要

The present invention is directed to systems and methods for compressing image data while at the same time, the speed of compression, the compression ratio (that is, reduced memory requirements) and the perceptibility of the decompressed image, even when the image data is compressed without segregation into its scanned and non-scanned components. Exemplary embodiments achieve such improved perceptibility regardless of whether the images are monochrome (having varying grey scale values) or color. In addition, improved perceptibility is realized in a manner which permits image data including scanned and/or unscanned images to be compressed in real-time.
