An image compression and decompression method encodes and decodes pixel data based on a color conversion method. Base on the relationships of corresponding color components of two adjacent pixels, the corresponding color components are encoded either by a white and black modification, a down-sampling or an edge modification. Based on the relationships of encoded color components of the two adjacent pixels, the corresponding encoded color components are decoded either by an inverse white and black modification, an up-sampling or an inverse edge modification.
