A pre-process of dither image data compression mainly divides the original image into x*y pixel pattern[A] filled out the original image, and allocates a dither pattern[B] with the same size(same column and row) as matrix[A]. The pixel value with same parity(same column, same row or same column and row) in pixel pattern is extracted to form a group. Each group has a corresponding element of dither pattern[B], and operating binary process with the element as threshold for all pixel values in same group to form a binary image data which could be compressed by conventional compression encoding.
