A video signal processing device comprising a subtractor for computing a difference signal between an input video signal and a video signal input a predetermined period before relative to the input video signal, a computer for applying a predetermined computation to the difference signal, an adder for adding that computation result to the input video signal or the video signal input the predetermined period before and outputting the result, a delay circuit for delaying the output of the adder by the predetermined period, and a dither generator for generating a dither pattern, being characterized in that the dither pattern generated by the dither generator is added to the signal output from the computer or the adder.
