    • A system processes an image containing a first line and a second line, where the first and second lines includes a plurality of pixels, to generate an interpolated line. The system selects a first and second set of pixels from the lines and generates a first set and second set of filtered values. The system identifies in the first line an edge location in the first set of the filtered values by a first filtered value of the first set of filtered values being at least one of less than and equal to a first predetermined value and a second filtered value of the fist set of the filtered values being at least one of greater than and equal to the first predetermined value. The system also identifies in the second line an edge location in the second set of filtered values by a first filtered value of the second set of the filtered values being at least one of less than and equal to a second predetermined value and a second filtered value of the second set of filtered values being at least one of the greater than and equal to second predetermined value. The system then interpolates based on the edge location of the first line and the edge location of the second line to generate an interpolated pixel of the interpolated line.

    • For large screen video displays using line-doubling to reduce scan line visibility, where a video source signal in standard interlaced format such as NTSC is converted to line-doubled non-interlaced format for progressively scanned display, visible motion degradations such as edge shimmer and strobe effects due to film-sourced video material are minimized by improved motion-detection video processing taught by this invention. In advance of actual display, successive fields are monitored for motion value in a first motion-detector and microprocessor comparator/analyzer where fields having high field-motion-value are detected as H-fields. Then, for display, each H-field is modified by pixel-averaging with a selected non-H-field. The regular and averaged fields are correctly sequenced to achieve vertical pixel alignment and smooth motion transitions thus minimizing film-source edge motion degradation. Film-mode entry and exit are accomplished automatically in a second motion-detector-analyzer that accomplishes fast film/video recognition and mode-switching. Film-mode entry and exit are each accomplished within a time period of one field, several times faster than in known art; such fast entry and exit are particularly important in avoiding visible motion defects under worst case conditions where regular video material is fragmented by frequent and/or non-synchronous spliced insertions of film-sourced or computer-generated portions.

    • Images may be stored on film or on one of the TV/video standards. Film comprises a sequence of frames each of which corresponds to the same point in time. Video, however, comprises a sequence of frames each comprising an interlace of 2 fields which successively scan the image and thus each field does not correspond to the same point in time.Due to these inherent differences, when converting from film to one of the TV standards and between the TV standards when at least part of the image originates on film, distortions are introduced particularly when there are any objects moving in the image.The present invention includes a vector motion estimator (10) providing motion vectors which are indicative of any objects moving and are used to manipulate the standards converter (8) so as to accommodate for the moving objects.
    • 图像可以存储在电影或电视/视频标准之一上。 电影包括每个帧对应于同一时间点的一系列帧。 然而,视频包括一系列帧,每个帧包括连续扫描图像的2个场的交错,因此每个场不对应于相同的时间点。 由于这些固有的差异,当至少部分影像产生于电影时,从电影转换为电视标准之一和电视标准之间,特别是当图像中有任何物体移动时,会引入失真。 本发明包括向量运动估计器(10),其提供指示任何物体移动的运动向量,并且用于操纵标准转换器(8)以适应运动物体。

    • A scan line doubler includes an input for receiving a video signal at a first scan rate, an output for providing a video signal at a second scan rate twice the first scan rate, a main path leading between the input and the output. The main path includes a scan line interpolation circuit for averaging pixels over two adjacent lines, a two-to-one scan line compression circuit for compressing original and interpolation scan lines into a scan line doubled format, and an optional additive path insertion location between the line interpolation circuit and the two-to-one line compression circuit. An openable connection path bridging the optional additive path insertion location is replaceable with an additive signal processing path including a field delayed pixel extraction circuit, a control circuit for generating a control in relation to detection of motion within the main path video signal, and a combining circuit responsive to the control for adding to the main path the one field delayed pixels and subtracting the line interpolated pixels, whereby when the optional path is connected, the scan line doubler operates in the horizontal, vertical and temporal domain, and when the optional path is not connected, the scan line doubler operates in the horizontal and vertical domains. An improved and simplified three-dimensional scan line doubler is an aspect of the present invention.
