    摘要： A video signal processing circuit is provided to display an image of a standard television signal on a display unit with a 6:9 aspect ratio by enlarging an image of a video signal in the horizontal and vertical directions by a magnification factor which depends on the feature of the standard television signal. The processing circuit includes a first memory circuit which reads out the stored video signal in response to a read clock different from the write clock and generated by a stable frequency source so that the image of the video signal is expanded in the vertical direction, a second memory circuit which implements time-base compression for the output of the first memory circuit and thereafter expands the signal, a spatial filter which implements filtering for the output of the second memory circuit, an enlargement control circuit which control the above-mentioned circuits, and a synchronizing processing circuit. The circuit arrangement enables video signals of various image sizes, such as for movie pictures, to be displayed by signal conversion on a display unit with a 16:9 aspect ratio, and is capable of suppressing jitters of video signals.

    摘要： A motion information signal generating circuit comprises a motion detecting circuit for detecting a piece of motion information from a digitized television signal; a temporal-spatial signal processing circuit for expanding a signal representing the so detected motion information both in time and space and a noise eliminator circuit connected between the motion detecting circuit and the temporal-spatial signal processing circuit. The noise eliminator circuit has at least one 1H memory to detect the correlation between the motion information signals pertaining to two adjacent picture elements which are one horizontal sweep line part, and for instance, the motion information signal of a smaller data quantity is selected, thereby preventing appearance of a false motion signal which would be caused by a noise of increased amplitude.

    摘要： The present invention provides a movement correction frame count transformation apparatus for carrying out frame count transformation processing on a picture signal. In the apparatus, an input picture signal (S1) of interlaced scanning is converted into a signal (S2) of sequential scanning by an IP conversion unit (1). A movement detecting unit (3) detects movement detection signals (MD1 and MD2). A block unit movement vector searching unit (4) detects a block unit movement vector (BMV) by carrying out block matching processing. A movement vector correcting unit (5) carries out miniblock division processing to generate a movement vector (BV) if a movement correction error is equal to or greater than a threshold value. A pixel unit movement vector generating unit (6) generates a movement vector with a smallest error component between a frame signal of a current frame and a frame signal of an immediately preceding frame as a movement vector of a pixel. An MC interpolation frame signal generating unit (7) generates an interpolation frame in movement correction processing carried out by a median filter in order to produce a signal (S4) of sequential scanning as a result of frame count transformation based on movement correction.
