摘要： In a solid-state imaging device, a chrominance signal different from a signal to be obtained at a specified time among a plurality of chrominance signals to be successively obtained from a solid-state image sensor is interpolated with the chrominance signal obtained directly before the time of interpolation, or with the chrominance signal of a picture element corresponding to the signal to be obtained at the time of interpolation based upon the subject being achromatic. The particular signal to be used for the interpolation is decided based upon the difference between the signal to be obtained at the time of interpolation and a signal of the same chrominance obtained one cycle before the time of interpolation, or the differences between signals obtained directly before the time of interpolation and to be obtained directly after the time of interpolation and the chrominance signals obtained one cycle before the times of these signals.
