Abstract: Method and apparatus for producing a frozen television picture are disclosed. Successive fields of picture information are generated by an interpolator which is responsive to a video input signal. These successive fields are applied to the input of a first field store device. The video input signal is applied to the input of a second field store device so that the successive fields of the video input signal correspond in time to the successive fields generated by the interpolator. Lines from the respective field store devices are sequenced repetitively to form a video signal representing the frozen television picture. The interpolator generates fields which, when displayed with corresponding fields of the video input signal, minimizes motion-induced artifacts without unduly degrading vertical resolution.

Abstract: The present invention relates to a video signal processor with progressive scan. According to the invention, it comprises a delay means receiving a video signal Y1 at a given line frequency and producing a first output signal Yd delayed by an interval of one frame minus a half-line, a second output signal delayed by an interval of one frame plus a half-line and a third output signal delayed by an interval of a double frame; a first means 66,68 averages the first and second video signals; a second means 62, 64 averages the input signal and the third video output signal; a third means 70, 72, 74 undertakes the high-pass filtering of the first averaged signal and the low-pass filtering of the second averaged signal and combines them; and a means of acceleration 82, 84, 86, 88, 90, 92 compresses the first output signal as well as the interpolated output signal and intercalates lines of the signals compressed in time to form a non-interlaced video signal Y2 with double the line frequency. The invention applies in particular to television.
