发明名称 IMAGE PROCESSING APPARATUS
摘要 PROBLEM TO BE SOLVED: To provide an image processing apparatus that accurately detects a character area in dots and applies optimum processing to each area so as to reproduce even characters in the dots with high accuracy. SOLUTION: An in-dot character area signal generating section 33 is provided with a number of isolated point count section 76, a number of inner edge count section 79, and a continuity detection section 81. Then the in-dot character area signal generating section 33 utilizes it that features of a dot area are entirely reverse to those of an in-dot character area to discriminate the in-dot character area on the basis of the detection results of an isolated point discrete value by the number of isolated point count section 76, an inner edge discrete value by the number of inner edge count section 79, and the presence of the continuity of inner edges by the continuity detection section 81. Thus, the image processing apparatus can accurately discriminate the in-dot character area, apply proper image processing even to character areas in dots and then reproduce characters in the dots with high accuracy.
