Abstract
An object is to suppress a false color and moire that occur in a high-frequency region. Color interpolation circuits of a color-difference signal generating circuit separate an image signal obtained from an image pickup device, in which a plurality of color filters are arranged in a predetermined pattern and in which pixels corresponding to the respective color filters are provided, into image signals of the respective color filters (R, G1, G2, and B), and perform an interpolation process on the image signals of the respective color filters. Then, a false color determining circuit determines whether a target region is a high-frequency region on the basis of at least any of slopes of image signals of the G1 filter and the G2 filter and a difference between the image signals of the G1 filter and the G2 filter in the target region.
