Filed: 1999-02-15
Abstract: PROBLEM TO BE SOLVED: To improve the compressibility of multi-valued image data by outputting a binarize-expressed gradation pattern corresponding to a pixel value and selecting and compressing a gradation pattern corresponding to the pixel value so as to increase regularity seen from an arraying direction. SOLUTION: Multi-valued image data are accepted from an input device 1 to be compress-processed and outputted to an outputting device 2. Then, a pixel scanning part 3 fetches each pixel value included in a multi-valued image. A pattern conversion part 4 accepts the pixel value outputted by this part 3 and outputs the binarize-expressed gradation pattern corresponding to the pixel value. A data compressing part 5 arrays the gradation patterns outputted by the part 4 in the order of outputting and executes data compression by using regularity seen from the arraying pattern. In this case, the part 4 outputs the gradation patterns corresponding to each pixel value which is obtained by selecting dot array so as to increase regularity seen from the arraying direction.
