Abstract:
1. An image processing method for compressing image data, comprising: (a) obtaining a block composed of part of or all of the image data: (b) determining whether the obtained block is color or monochrome; and (c) performing, in the case where the obtained block is determined to be color, compression processing in parallel for a predetermined number of elements of a predetermined color system, and performing, in the case where the Obtained block is determined to be monochrome, the compression processing in parallel for individual areas obtained by dividing a division block containing, the obtained block into a predetermined number of pieces for a single component of the predetermined color system; wherein, in the case where the obtained block is determined to be monochrome, in (c), the individual are set by dividing the division block into a predetermined number of areas by using different methods for one portion of and the remaining portion of the division block, and wherein, in the case where the obtained block is determined to be monochrome, in (c), the individual areas are set by equally dividing the one portion of the division block in the left-right direction and, for the remaining portion of the division block, the individual areas are set such that areas to be units when the compression processing is performed alternate with each other.
