PURPOSE:To perform real time processing, by reading an original designated for the area with a plurality of marks having a specific color optically, performing the discrimination of color from an optical image, obtaining a pluraity of color data and processing the rest color data with this color data. CONSTITUTION:An area AER is designated with three blue key marks M1-M3 on a two-color print original MAT in red and black. The mark M1 is for area designation start toward the main scanning and sub-scanning direction, the mark M2 is for the end of area designation toward the main scanning direction and the mark 3 is for the end of area designation toward the sub-scanning direction. The original MAT for area designation is read optically, and a plurality of color data are obtained through the color discrimination from the optical image obtained with this reading. The rest red and black color data can be processed with the blue color data. |
