ABSTRACT:
An exposure signal representing a halftone image is generated by executing tone correction on at least either of an image signal and n pieces of dot pattern signals, and by comparing the image signal with the n pieces of dot pattern signals after the tone correction. The tone correction characteristics are set to compensate for a difference in dot gain characteristics between dot types. The halftone image is accordingly reproduced with the compensated dot gain characteristics.
