PROBLEM TO BE SOLVED: To standardize a dedicated circuit for a half-tone processing that artificially expresses the larger number of gray scales than the number of output gray scales for every dot between devices each having the different number of gray scales of an output gradation value, and optimize it for each type of apparatus, by changing a conversion pattern from input gray scales to the output gray scales for every coordinate in a continuous region having a predetermined area.SOLUTION: An image processing apparatus is an apparatus that relatively increases the number of indexes, in the case of corresponding to a low gradation level as a half-tone level that the number of gradations of a corresponding output gradation value is relatively small. |
