发明名称 Signal processing device, signal processing program and electronic camera
摘要 The present invention includes a color converting section carrying out color conversion processing and a coefficient correcting section setting a correcting coefficient group to a coefficient group of the color conversion. The coefficient correcting section sets a local area containing a pixel to be processed, and calculates “feature information of the local area” containing at least one of averaged color information, averaged luminance information, and flatness on the basis of the pixel signals of the local area. The coefficient correcting section determines a correcting coefficient group to be used for the pixel to be processed on the basis of the feature information of the local area. With this construction, the present invention suppresses influence of noise when changing the color conversion processing for each pixel.
