ABSTRACT:
An apparatus for determining motion vectors between a current frame and a previous frame of digital video signals apparatus comprises a subblock motion vector detector for detecting a subblock motion vector for each of the subblocks included in a panning block within the current frame; a panning vector detector for detecting a panning vector for the panning block; a motion vector determination circuit for determining whether the previous frame is motion compensated by the panning vector to produce a control signal; and in response to the control signal, selecting the subblock motion vector from the subblock motion vector detector or the panning vector from the panning vector detector as an output of the motion vector detecting apparatus.
