Patent ID: 8405769

Claim:
A method, comprising: determining a minimal sum of absolute differences (SAD) for a pixel in an interlaced frame; and comparing the minimal SAD to a first threshold and second threshold value, such that when the minimal SAD is less than or equal to the first threshold value, smoothness and consistency checks are performed; and when the minimal SAD is greater than the first threshold value and less than or equal to the second threshold value, the smoothness and consistency checks are performed, and supplemental checks are performed, wherein the outcome of the smoothness and consistency checks and, when performed, the supplemental checks, determine whether a motion compensation interpolation value or a spatial interpolation value is selected for de-interlacing the interlaced frame; wherein said determining and comparing are performed using a processor, and wherein the supplemental checks comprise: a SAD check; a best angle check; a median filtering check; and a minimum operation check; wherein passing the SAD and best angle checks, and at least one of the media filtering and the minimum operation checks represents passing the supplemental checks.
