Abstract:
A deinterlacing method for video signals based on an edge-directional interpolation comprising:(a) forming an intermediate video frame from a video of a current field; (b) setting a plurality, of edge directions with respect to a pixel in the intermediate video frame, and calculating mismatch values respectively associated with the set edge directions; (c) comparing the mismatch values of the set edge directions with one another and determining an edge direction among the set edge directions; (d) calculating an interpolation value of the pixel using information about the edge directions along with the intermediate video frame; (e) checking an accuracy of the determined edge direction using the information about the edge directions and determining whether the determined edge direction involves side effects; and (f) if it is determined that the determined edge direction is reliable, then selecting the interpolation pixel value, associated with the determined edge direction, as a deinterlacing value.
