<P>PROBLEM TO BE SOLVED: To achieve an increased processing efficiency when executing image processing to a binarized image by selectively using a bit-map form and a run-length form. <P>SOLUTION: An image processor 1 compares a processing cost in the case of a bit-map form and a processing cost in the case of a run-length form concerning a binarized image to which image processing is to be executed, selects the data form of which processing cost is the lower and executes the image processing to the binarized image with it, and outputs the binarized image that has been processed. An image processing device 2 compares a processing cost in the case of the image processing in which entropy coded binarized image data are decoded to binarized image data of the bit-map form and a processing cost in the case of the image processing in which the entropy coded binarized image data are decoded to binarized image data of the run-length form, decodes the entropy coded binarized image data to the binarized image data of the data form of which processing cost is the lower, executes the image processing, and outputs the binarized image data that have been processed. <P>COPYRIGHT: (C)2006,JPO&NCIPI |
