IPC: H04N1/409
Filed: 1998-03-18
Abstract: PROBLEM TO BE SOLVED: To obtain an image processor which improves the reproducibility of a character edge part by changing correction content to image data that is necessary for image formation based on a decision result by an edge area deciding part and a detection result of a character background boundary part by a boundary deciding part.

C, M and Y signals are subjected to the same processing and a K signal undergoes different processing by the content of image correction. An area discrimination result is inputted to a character edge reproduction controlling part and is converted into a selection signal that switches correction processing of the part 451. Thus, reproducibility is improved without character hollow phenomenon.
