Abstract
Aspects of the invention for converting interlace formatted video to progressive scan video, may include a color edge detector block (306) adapted to determined edges in interlaced formatted video. A threshold and gain processor block (308) coupled to the color edge detector block (306) may be adapted to quantify a likelihood of motion for each pixel comprising at least a portion of the interlaced scanned video using a motion value. A binder block (310) coupled to the threshold and gain processor block (308) may be configured to combine the motion value for each component of a luminance and chrominance of each of the pixels. A resampler block (314) may be coupled to the binder to determine an actual pixel value. The resampler block (314) may include at least one of a vertical and a horizontal filter adapted to determine an actual value of each of the pixels in at least a portion of the interlaced scanned video. A post-processor block (312) may be coupled to the binder block (310) and the resampler block (314) and adapted to remove unwanted signals such as noise from signals generated by the binder block (310).
