PROBLEM TO BE SOLVED: To provide a pixel signal processor where moire can be reduced. SOLUTION: Respective pieces of pixel data forming raw picture data have information on one color among R, G or B. Interpolation picture data where respective pieces of pixel data have all color information of R, G and B is generated based on raw picture data. A correction coefficient generation circuit 26 detects a stepwise change of the color, namely, a color edge based on raw picture data and outputs a correction coefficient K having a numerical value corresponding to a degree of the color edge. A correction circuit 28 corrects interpolation picture data so that quantitative deviation between color information of R, G and B is suppressed in a part where the color edge is detected. An achromatic color appears in the part where the color edge is detected rather than a chromatic color which is not intended. COPYRIGHT: (C)2004,JPO&NCIPI |
