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 S NT 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 S XG 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 S NT 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 S XG. A video signal S2N acquired by image adaptive conversion processing is a video signal of high image quality. A video signal S XG 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 S XG acquired only by interpolation processing based upon a video signal S NT.

Abstract: An image signal processing apparatus receives an image signal which has been generated by subjecting a telecine-converted image to double speed conversion. The image signal processing apparatus is operable to process the telecine-converted image signal by forming one film frame from four fields, a first field on the basis of a difference value calculated between pixel signal levels, and shifting the position of a detected pixel in a vector direction of a motion vector such that an amount of shift is progressively increased in accordance with a transition made from the identified first field to the subsequent fields.

A video signal converter is composed of an image adaptive double-speed conversion circuit for converting a video signal SNT to a video signal SZN 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 wish a video signal SXG acquired only by interpolation processing based upon a video signal SNT.

Abstract: A video source selecting system for a television receiver has a built-in video tape recorder (video deck) for sequentially selecting for display, a plurality of video signals on various channels, such video signals including at least a video signal from the built-in video deck, and a video signal from at least one external video input terminal. A selected video signal is supplied to a monitor television receiver. When the built-in video tape recorder is placed in its playback mode, the plurality of video signals are switched selected sequentially, while when the built-in video tape recorder is not placed in its playback mode, it is skipped by the switch, whereby the order in which the video signals are switched is in response to the operational state of the built-in video tape recorder.
