<P>PROBLEM TO BE SOLVED: To automatically apply the most suitable conversion expression in response to an actual image. <P>SOLUTION: This image processor or the like obtains a parameter a corresponding to a magnification within a brightness-reproducible range, and a parameter b corresponding to an offset amount, by considering an end part entered into an inside by a prescribed distribution ratio in each of an upper end and a lower end, as an end part of a brightness distribution (step S116), after finding a brightness y as to an image data while thinned or likely in a step S102, and a converted side brightness Y is automatically converted thereby with respect to the conversion origin side brightness y, using an expression of Y=ay+b or the like. <P>COPYRIGHT: (C)2010,JPO&INPIT |
