Abstract
Color information having R, G, B components is entered. When an optic nerve head contained in the color image information is designated by an image processor and region designation unit, an image compression unit encodes the B component, which is included among a plurality of color components in this designated region, at a compression rate lower than that in a region other than the designated region, and encodes the G component and the B component other than in the designated region at a higher compression rate.
