Abstract
A method for deinterlacing video includes constructing a temporary frame of deinterlaced video based on a first (i.e., current) field of interlaced video, wherein the temporary frame includes pixels in lines of the temporary frame associated with the first field of interlaced video, placeholder pixels in identified areas of motion in lines of the frame associated with a missing field of interlaced video, and pixels from an opposite field of polarity of interlaced video in areas without motion. The method further includes replacing the placeholder pixels in the identified areas of motion with pixels interpolated using an edge direction interpolation scheme based on pixels in the first field of interlaced video, resulting in a reconstructed frame. In one example, a motion adaptive interpolator may construct the temporary frame, and an edge directional interpolator may generate the reconstructed/deinterlaced the frame.
