摘要： A video scan converter has a deflickering circuit that attenuates spatial frequency components that combine high vertical spatial frequency with low horizontal spatial frequency. The resulting signal is converted from progressive scanning to interlaced scanning by appropriate selection of even and odd horizontal scanning lines. The deflickering circuit may also expand a selected part of the video signal by vertical interpolation, followed by vertical low-pass filtering, in which case a separate horizontal interpolating circuit expands the selected part horizontally, preferably after progressive-to-interlaced scan conversion.
摘要翻译： 视频扫描转换器具有衰减电路，其衰减将高垂直空间频率与低水平空间频率相结合的空间频率分量。 通过适当选择偶数和奇数水平扫描线，将结果信号从逐行扫描转换成隔行扫描。 断线电路还可以通过垂直内插扩展视频信号的选定部分，随后垂直低通滤波，在这种情况下，单独的水平内插电路将所选择的部分水平地扩展，优选地在逐行扫描到逐行扫描转换之后。
