ABSTRACT:
A hybrid deinterlace mechanism employs motion detection as a precursor to select the value for each missing pixel of a deinterlaced frame. If the missing pixel is found to belong to a steady or non-motion portion of the image, then its value is replaced by the corresponding value in the adjacent field (i.e., merging is performed). Otherwise, (where image motion is present) spatial interpolation, preferably edge-adaptive interpolation, is employed to determine the value of the missing pixel.
