  • Interlaced-to-progressive video
    Patent number: 7990471
    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.
    Type: Grant

  • Color filter array and method
    Patent number: 7653240
    Abstract: Color filter array demosaicing as is useful in digital cameras, still and video, using a single sensor includes blending of directional and non-directional interpolations. Directional interpolation uses edge detection with lowpass filtering with neighboring pixels for erroneous detection correction.
