| 摘要 |
This invention relates to an image processing apparatus. A black data generator of the image processing apparatus is operated such that a calculator solves the equation (1) using a maximum value, max(C,M,Y), detected by a maximum value detector, a minimum value, min(C,M,Y), detected by a minimum value detector, and a coefficient beta as parameters to output a black weight indicia alpha for black data: alpha -1-{max(C,M,Y)-min(C,M,Y)}/ beta (1) A multiplier solves the equation (2) to output a value K for the black data: K= alpha xmin(C,M,Y)(2) Then, a character UCR converter, a photography UCR converter, and a halftone dot UCR converter output an output value BK for the black data corresponding to the value K as address data.
