ABSTRACT:
An image signal restoring apparatus of the invention is of the type in which from the luminance information signal and chrominance information signal transmitted thereto, the original luminance and chrominance signals are restored, and operates in such a manner that when it is judged that the inputted luminance information signal is usable to restore the original luminance signal and the inputted chrominance information signal is unusable to restore the original chrominance signal, the inputted luminance information signal is used to detect presence or absence of motion in the image represented by the luminance signal corresponding to the luminance information signal, and, based on the detection result, an interpolation chrominance signal is produced, whereby it becomes possible to stably restore images of high visibility and natural motion.
