a correction value generator for generating correction values regarding light amounts at the respective target pixels within the blocks based on the plurality pieces of light amount correction data which are held in the correction value memory; and
an image field edge brightness reduction corrector for correcting brightness reductions at the respective pixels based on the correction values regarding light amounts generated by the correction value generator.
