Abstract:
1. A signal processing apparatus for processing image pickup signal output from image pickup elements and generating color image data, the image pickup signal including three kinds of color signals and luminance signals, the signal processing apparatus comprising: a synchronization processing unit that disposes signals included in the image pickup signal at respective coordinate positions, and carries out a interpolating processing that interpolates to the three kinds of color signals at the pixel positions which indicate the respective coordinate positions corresponding to pixel data of the color image data to be generated, wherein the interpolating processing of the color signals to be carried out by the synchronization processing unit includes a luminance-use-estimating processing that estimates at each pixel position corresponding to one of three kinds of color signals, another one kind of color signals to be interpolated by using (i) color signals having said another one kind of color signals and existing around the pixel position of said one kind of color signals and (ii) the luminance signals around the pixel position of said one kind of color signals.
