Patent ID: 7982782

Claim:
A signal processing device, comprising: a color converting section multiplying an input color pixel signal by a transformation matrix to execute color conversion processing; and a coefficient correcting section setting a correcting coefficient group to a coefficient group of the transformation matrix, wherein the coefficient correcting section includes an analyzing section setting a local area containing a pixel to be processed and calculating averaged color information and flatness on the basis of plural pixel signals of the local area, an aberration judging section judging whether a condition (1) the averaged color information is in a hue range of any one of green and magenta, and a condition (2) the flatness is lower than a predetermined threshold value and indicates a color boundary or edge portion are satisfied, and a coefficient determining section setting a correcting coefficient group for decreasing saturation to the coefficient group to be used for the pixel to be processed when the conditions (1) and (2) are satisfied in the aberration judging section.
