摘要： 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.

摘要： An image signal processing unit includes a frame rate conversion circuit performing double frame rate conversion on an input image signal from a first frame frequency to a second frame frequency. When performing frame rate conversion with the motion correction process, a motion vector is determined between a first frame image and a third frame image, and three interpolation frame images are formed through the motion correction process to the first frame image based on the motion vector, and are inserted between the first and third frame images so as to establish the second frame frequency. When performing frame rate conversion without the motion correction process, an interpolation frame image same as the first frame image is inserted between the first and second frame images, and an interpolation frame image same as the second frame image is inserted between the second and third frame images.
