Abstract: PURPOSE:To surely read out a prescribed color component other than a white and black components by forming a color correcting means for correcting picture elements discriminated as the 1st color to white picture elements when a prescribed number or more of the picture elements discriminated as the 1st color are arranged on the periphery of picture elements decided as black elements by a color separating means. CONSTITUTION:A color operating circuit 20 separates the ratio K of inputted signals R, C, and when the ratio K exceeds a prescribed value alpha(0, 4), discriminates whether the signal R is larger than a prescribed value beta(0, 4) or not, When the signal R is larger than the value beta, the picture element is regarded as a red picture element, so that the circuit 20 sets up logical levels '1' and '0' on a read picture signal R1 and a white and black picture signal B1 corresponding to the picture element respectively and outputs both the signals R1, B1. When the signal R is equal or less to/than the value, the picture element is a white or black picture element, so that the circuit 20 sets up logical level '0' on the red picture signal R1 and a logical level obtained by binary-coding the signal C by a prescribed threshold level on the signal B1 and outputs both the signals. Consequently, a prescribed color component other than white and black components can be surely read out with high quality.
