Abstract
This invention is a preprocessor apparatus and method algorithm facilitating black bar detection in video frames or fields. The preprocessing marks a sharp discontinuity between pixels a predetermined distance apart on each line. On first detection of this discontinuity the location and pixel value is stored. The location and pixel value is also stored for the last discontinuity in the line. This data enables software to detect top horizontal bars, bottom horizontal bars, left vertical bars and right vertical bars.
