The digital camera (100) has an image processor that corrects an input image for a spatial frequency band. The edge enhancement block (106) computes an edge component for band correction. A signal interpolated at color interpolation block (107) to make compensation for a color component missing from each pixel of a single-chip image is then converted at YC transform block (108) into a luminance signal and a color difference signal after tone correction, the luminance and color signals sent out to YC synthesis block (110) and color saturation correction block (109), respectively. Then, the color saturation correction block (109) controls the color saturation of the color difference signal to send it out to YC synthesis block (110). At the same time, the edge component computed at edge enhancement block (106) is sent out to YC synthesis block (110), too.
An image processor adapted to correct the spatial frequency band of an input image, characterized by comprising a plurality of band correction means having mutually distinct band correction characteristics, a feature quantity computation means adapted to figure out a feature quantity in the neighborhood of each pixel of the input image, and a synthesizing means adapted to synthesize the outputs of said plurality of band corrections means on the basis of said feature quantity.
An image processing program to correct image data for a spatial frequency band, which let a computer implement steps of reading image data, implementing a plurality of band corrections having mutually distinct band correction characteristics, figuring out a given feature quantity in the neighborhood of each pixel of said image data, and synthesizing the outputs of said plurality of band corrections on the basis of said feature quantity.
