Abstract
In a gamma corrector for handling gamma correction data used in performing gamma correction on image data represented by plural component colors for each of the component colors, a storage stores common data employed in common in predetermined gamma correction data in one-to-one correspondence to the plural component colors when generating final gamma-corrected image data. Another storage stores, for each component color, reproduction data represented by removing the common data from the final gamma-corrected image data of each component color in the predetermined gamma correction data. A data processor distributes input image data of each component color to both common and reproduction data to thereby generate the address data. A data coupler generates the common and reproduction data according to address data from the storages and employs the generated common and reproduction data to generate final gamma-corrected image data for image data of the component colors.
