发明名称 Apparatus, method and program product that calculates a color blending ratio so security dots reproduced in a monochrome image are substantially undetectable
摘要 The invention provides an image processing apparatus, an image processing method, a recording medium and a program capable of suppressing security dots from being reproducible visibly while enhancing reproduction of a color, in an original, specified by a user, in the process of forming a monochrome image from a color image. The image processing apparatus includes a unit for taking a color image, a unit for separating a color image into respective color elements, a unit for judging the security dots through the use of the separated data, and a unit that, when it is judged that security dots are included, recalculates the blending ratio through the use of the security dot judgment result to convert the color image into a monochrome image.
