Color separation image correcting device

Abstract

Abstract PURPOSE:To attain the realization with a simple adding processing and to simplify the constitution of a device by reading color correcting data of at least two before and behind points including input color separation image data and using these color correcting data. CONSTITUTION:To terminals 63b-63r, respective color data of B, G and R are inputted, high-order 5 bits are supplied to a memory means LUT 61 as the address data, and thus, corresponding color correcting data Y, M, C and K are read. These input color data B, G and R are further supplied to carry means 65-67. Consequently, from means 63-67, the color data of 5 bits are outputted in which a low-order 1 bit is carried. These carried input color data B, G and R are supplied to an LUT 62 as the address data and thus, color correcting data Y, M, C and K stored into the corresponding address are read. The color correcting data read from LUT 61 and 62 are supplied to an arithmetic means 68 for calculating a mean value and the mean value processing of both is executed.
