Abstract: There is provided an image display apparatus which automatically detects a picture defect and shifts an image region to eliminate the picture defect. The image display apparatus includes a memory unit for temporarily storing an input image signal, a memory control unit for controlling a readout start address for the memory unit, a display unit to which the image signal read out of the memory unit is supplied, a detection unit of an aspect ratio of the input image signal, and an address control signal generation unit to which an aspect ratio detection output is supplied from the detection unit and which generates a readout start address control signal for the memory unit from the input image signal. When the input image signal having an aspect ratio different from an aspect ratio of image screen display of the display unit is supplied, a readout start address is controlled on the basis of the address control signal generated by the address control signal generation unit. By this, an image region is automatically shifted and a picture defect is prevented without changing the aspect ratio of the input image signal when an object is a human figure.

Abstract: This invention relates to a video signal converter, a conversion method of video signal, respectively suitable to be applied when a video signal according to National Television System Committee (NTSC) is illustratively converted to a video signal corresponding to an extended graphics array (XGA), an image display unit using the converter and conversion method, and a television receiver. A signal in each field of a video signal SNT according to NTSC in which the number of lines is 252.5 (effective line number is 240) is converted to a signal in each frame of a video signal SXG corresponding to XGA in which the number of lines is 840 (effective line number is 768). A video signal converter is composed of an image adaptive double-speed conversion circuit for converting a video signal SNT to a video signal S2N according to an interlaced scanning method in which the number of lines is doubled and an interpolation circuit for converting the video signal S2N to a video signal SXG. A video signal S2N acquired by image adaptive conversion processing is a video signal of high image quality. A video signal SXG acquired by interpolation processing based upon the video signal S2N is a video signal of high image quality free of the deterioration of the quality of an image, compared with a video signal SXG acquired only by interpolation processing based upon a video signal SNT.
