Abstract
In this process the frames are composed of frames with parity of a first type (1, 2) interlaced with frames with parity of a second type. It consists in interpolating the missing lines in the direction of the motion (3) on the one hand, by vertical intra-frame linear filtering (6) on the other hand, and in switching between these two values (8) depending on the confidence accorded to the motion vector.
