PURPOSE:To prevent image quality at a joint part of an band image from being deteriorated by a simple structure. CONSTITUTION:Respective data of RGB obtained by reading are converted to data of YMC with a logarithmic conversion circuit 6. Then, they are converted to appropriate data of YMCK with an output masking circuit 8. The converted data of YMCK are made binary with a pseudo halftone processing circuit 10 via a gamma-conversion circuit 9, and recorded with a recording head of each color. Herein, a conversion characteristic controlling part 50 judges whether or not a pixel to be watched is positioned near an end part of a recording head and generates a parameter corresponding to each. The output masking circuit 8 receives the parameter, and converts the outputted data of YMCK according to the parameter. |
