Abstract
A color original image is pre-scanned in order to detect respective color components of sample pixels. Then, it is decided whether each sample pixel has color components corresponding to a designated 'memory color' within a predetermined allowable error range. A 'memory color' represents colors with respect to which persons have preconceived notions, i.e., memories, as to their correct tone, hue, etc., for example, the color of the sky, trees, or the like. When the number of sample pixels having the memory color is larger than a threshold value, a predetermined color separation rule is corrected to obtain a corrected color separation rule which is used for separating the color original image into components suited for reproduction of an image corresponding thereto.
