Abstract

Disclosed is an image data compression method including calculating an estimated error of each of a plurality of compression modes for compressing image data based on the image data and a weighted value in each sub-pixel, selecting one mode among the plurality of compression modes based on the estimated error of each of the plurality of compression modes, and encoding the image data according to the selected mode.
