Abstract

PURPOSE:To realize a data process in real time and to perform a picture process with a simple designation of a region, by reading optically an original to obtain a prescribed number of color data from an optical imge and processing other color data based on one of the plural color data. CONSTITUTION:An original MAT is printed in two colors such as red and black, etc., and the region on the MAT is designated by a blue loop having a certain thickness. An optical image is read through an optical system including a light source SOL, reflectors RM1 and RM2, a beam splitter SB, photoelectric converters PHB and PHR, etc. The bright and dark areas of the blue and red images on the MAT are detected by the PHB and PHR, and the blue, red and black data DBU, DRE and DBK are delivered from a color discriminator DMC. Then the data DBU is processed by an edge detector EDE, a region detector DEA, a data selector SDT, etc. The data DRE and DRB are applied to a data switch DSW from line memories MRE and MBK. The picture data is processed by the output given from the selector SDT.
