Abstract
In one embodiment of the present invention, motion compensated interpolation is performed by locating full frame conceal and reveal areas, determining intermediate frame occlusion areas of an interpolated frame of the displayable output by locating intermediate frame conceal areas based on projected locations of pixels within the full frame conceal areas using primary forward motion vectors and information about a time slot for the interpolated frame, and by locating intermediate frame reveal areas based on projected locations of pixels within the full frame reveal areas using primary backward motion vectors and information about the time slot for the interpolated frame. The intermediate frame conceal areas are then modified by projecting locations of pixels using secondary forward motion vectors and the intermediate frame reveal areas are modified by projecting locations of pixels using secondary backward motion vectors.
