Abstract:
A method of improving the speed and efficiency of electronic data transmission, comprising the steps of:a) acquiring input image data which represents the light intensity of an image; b) segmenting said input image data to form a plurality of image data blocks; c) analyzing at least one of said image data blocks to determine its image data content; d) providing a single stage of plural image processing modules, wherein each image processing module processes image data at a different image quality level; e) selecting, based on the determined image content, a single image processing module among the plurality of image processing modules for receipt of the image data block; f) transmitting said image data block to the selected image processing module; and g) processing said received image data block in said selected image processing module; wherein said module selecting step further comprises the steps of: 1) obtaining the image data block; 2) mapping said image data block to a single codeword using at least one look up table; and 3) transmitting said image data block to the module as designated by said single codeword.
