Abstract

See full text

A video signal processor which can reduce the noise of quantized video signal. A bit-added video signal is prepared by adding a bit string of m-n bits to the least significant bit side of the input video signal. A smoothed video signal is prepared by performing smoothing processing on this bit-added video signal. The difference between the bit-added video signal and the smoothed video signal is compared with a predetermined threshold value. Either the bit-added video signal or the smoothed video signal is selected according to the comparison result. The selected video signal is output as the bit-extended video signal.
