Abstract
Integrated circuits with interpolating circuitry for deinterlacing video data are provided. Each frame of video data may include a field of pixels from every-other row of the frame. Edge detection circuitry may generate an edge map for the field. The edge map may be filtered to remove weak edges from the map. Cartesian Hough transformation circuitry may perform Cartesian Hough transforms on the filtered edge map to generate a Cartesian Hough space histogram. The Cartesian Hough space histogram may be filtered to remove bins having insufficient counts. Offset mask generation circuitry may generate an offset mask based on the Cartesian Hough space histogram. Interpolation circuitry may generate interpolated pixel values for missing rows of the field using pixels from the field and the offset mask. The interpolating circuitry may generate deinterlaced video data that is free from image artifacts along low-angle edges using the interpolated pixel values.
