    • To enable a satisfactory suppression of overemphasized component after converting the number of scanning lines of video signal, when the video signal is converted in the number of scanning lines and a high-frequency component at least in a vertical direction of the converted video signal is emphasized, signals delayed by a plurality of stages of time equal to or more than a time required for converting the number of scanning lines are obtained by a delay circuit 18, and an appropriate delay signal is selected from among the plurality of delay signals by a selection circuit 19. The selected delay signal is compared with the emphasized video signal in emphasized-component detector circuits 16a, 16b and the overemphasized component is detected. Processing to suppress the emphasis is performed by suppressor circuits 13a, 13b with respect to a portion where the overemphasized signal component is detected.
