1. A method of processing image data comprising:
- providing image data defining a first frame comprising a plurality of blocks, each block having a motion vector indicative of a destination location in a second frame;
determining the number (N) of motion vectors indicative of a destination location within a distance of a target location in the second frame, the distance greater than zero; and
determining a change in state of occlusion of the target location based on N.

Abstract
A method of processing image data, comprising providing image data configured to display a first frame comprising a plurality of blocks, each block having a motion vector indicative of a change of location of the block between the first frame and a successive second frame and determining a change in state of occlusion of a first block of the plurality of blocks by reference to motion vectors having a destination in the first block.
