ABSTRACT:
A signal process for interpolating color signals is executed. In this process, color image data output from image sensor covered by a plurality of color filters that form a predetermined matrix is interpolated, horizontal and vertical correlation levels are discriminated on the basis of the color image data, first color difference signals are calculated by color-separating interpolated image data of respective colors in a direction with the higher correlation level on the basis of the discrimination result, and second color difference signals are calculated by a predetermined arithmetic operation different from first color difference signal calculation unit on the basis of the interpolated image data of respective colors. The calculated first or second color difference signals are selected and output based on the first and second color difference signals.
