Abstract
An image compression method to compress image data generated through a pixel array includes categorizing image data corresponding to a plurality of sub-pixels arranged adjacent to each other and generating first color information for a first color pixel; determining a reference value as a criterion for compressing the image data based on pixel values of the sub-pixels; comparing the pixel values of the sub-pixels with the reference value; and outputting results of the comparisons and the reference value.
