Abstract
A video signal processing apparatus A comprises: an adder for generating a second address value S which has a predetermined phase difference from a first address value S outputted by an address value output means and outputting the same; a selector for selecting either a first address value S or a second address value S to output as an output signal S ; a vertical synchronizing signal output means for outputting the vertical synchronizing signal S to the selector ; a ROM for outputting first data corresponding to the first address value S or second data corresponding to the second address value S as a signal S ; a loading hold mode flip-flop for preserving the first data; a loading hold mode flip-flop for preserving the second data; and a hue adjustment means B which adjusts the hue of the video signal by using the output signal S of the loading hold mode flip-flop and the output signal S of the loading hold mode flip-flop . Therefore, a video signal processing apparatus which can reduce a circuit size with maintaining performance can be provided.
