Abstract

PURPOSE:To obtain an ideal picture quality with a simple method, by recording a color picture on a recording paper on a basis of a prescribed number of reference color recording signals different from one another and obtaining color separation signals from this picture in a photodetecting device to correct colors. CONSTITUTION:Address 0 is sent to a ROM from a controller 12 to record color dot images on a recording paper through a selector 17, a dot former 18, etc. This picture reaches just under a photodetecting device 7 by the rotation of a drum 1 and is separated into three colors, and respective separated color signals are stored temporarily in a memory through an operator 14. Addresses 1, 2 113F 7 are sent to a ROM13 from the controller successively, and signals are stored in the incorporated memory similarly. Next, color separation signals R, G, and B of a picture to be recorded from a picture input device 9 are inputted to an operator 16 through a selector 10 to form a color picture through the selector 17 on a basis of constants stored in a memory 15. Similarly, all pictures are recorded. Thus, an ideal picture quality is obtained easily.
