摘要:
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.
