ABSTRACT:
Interlaced-to-progressive conversion with (1) 3-2 pulldown detection, (2) pre-filtering for field motion detection, (3) field motion detection with feedback, (4) field edge detection including direction angle detection by comparison of pixel differences with sets of more than pairs of pixels and a lateral edge detection probability by a lack of non-lateral angle detection, and (5) blending moving pixel interpolation and still pixel interpolation using field uniformity.
