Abstract
A method for carrying out a color correction in a digital manner in a picture reproducing machine such as a color scanner, a color facsimile, or the like, which is capable of saving a large volume of capacity of a memory, wherein a resultant value obtained from a combination of color separation signals which are obtained by scanning photoelectrically a color original picture, is represented in a plane coordinate system, and wherein the coordinates of the resultant value are transformed in order to correct hue and saturation by operating the color separation signals together with factors predetermined, thereby obtaining a combination of color-corrected color separation signals.
