    摘要: An input digital video signal is converted to an output digital video signal having a different frame rate and a different number of pixel lines per frame. A first series of progressive scan format frames is formed from the input signal. Then a second series of frames is formed from the first series of frames using motion compensated temporal interpolation between successive frames of the first series in producing at least some of the frames of the second series so as to provide the difference in frame rate. Before or after the second series of frames is formed, vertical spatial interpolation is performed so as to provide the difference in the number of pixel lines per frame.

    摘要: In, for example, a motion compensated video standards converter wherein blocks in a first field or frame of a video signal are each compared with a plurality of blocks in the following field or frame of the video signal for deriving motion vectors representing the motion of the content of respective blocks between the first field or frame and the following field or frame, further motion vectors are selected for assignment to those of the blocks for which less than a predetermined plurality of good motion vectors are derived as a result of the comparison, by ranking all the good, non-stationary motion vectors derived for the field or frame in order of frequency of occurrence, and selecting those motion vectors which occur most frequently, unless they fall within a predetermined window of pixel motion of a motion vector already selected.

    摘要: An input digital video signal representing a series of input frames with at least some of the input frames each having a first picture portion having a first acquisition characteristic (such as 60 Hz, 2:1) and a second picture portion having a second acquisition characteristic (such as 30 Hz, 1:1) is processed to produce an output video signal representing a series of output frames having generally the same acquisition characteristic (such as 24 Hz, 1:1). The method comprises the steps of distinguishing between the first and second picture portions in the input frames (for example by determining the difference between input fields (a.sub.1, a.sub.2 ; a.sub.3, a.sub.4 ; . . . ) of a pair, or by detecting a key signal accompanying the input video signal) and processing the first and second picture portions differently to produce the output frames.

    摘要: Image processing apparatus is described in which a source stream of data captured by a particular source is passed through a data splitter where it is split using one splitting technique into a plurality of split streams of data. These split streams of data each contain only part of the information within the source stream of data. The split streams of data are separately manipulated by a post production unit prior to being passed through a data combiner where they are recombined to form an output stream of data. The source stream of data and the output stream of data are of a higher resolution than the individual split streams of data. The post production unit includes at least one reformatter for reformatting the data stream to use a different splitting technique matched to the manipulation being performed in the post production unit.
