    摘要: A digital blanking reproducing circuit wherein video signals are converted into N (N: positive integer) bit digital signals and then signal-processed. On the basis of plural N bit signals during the blanking interval of the video signal, an M (M: positive integer, M>N) bit average signal and a plurality of N bit approximation data in the neighborhood of the average value signal are produced. The plurality of N bit approximation data are time-divisionally output in a time-division ratio decided in accordance with the lower order (M - N) bit data of the average signal. Thus, the signal processing of the N bit signals provides the accuracy equivalent to that of M (M>N) bit signals.

    摘要: A television receiver which can display images in different displaying forms on a display screen with an aspect ratio of 16:9 by controlling the video chroma processing circuit by the micro computer by operating the remote controlled signal acceptor or the key switch has memories. The first memory stores video control data for each displaying form and the second memory stores appointed data for designating predetermined video control data. When the displaying form is changed by operating the remote controlled signal acceptor or the key switch, the micro computer reads the video control data corresponding to the displaying form which is newly set from the first memory according to the appointed data of the second memory and changes, for example, the contrast characteristic in the signal processing circuit according to the read data. By doing this, in the television receiver which is applicable to both a high quality television system and the conventional television system, when displaying images of conventional television signals in different displaying forms on a display screen with an aspect ratio of 16:9, the most suitable image quality can be obtained for each displaying form.

    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.
