<p>Video motion detection apparatus comprises means for applying a motion test to detect inter-image motion between two or more test images, the motion test providing a test result providing a motion vector and an indication of the integrity of the detected motion vector; and means for applying the motion test to one of the test images, to detect intra-image similarity within that test image; in which the motion vector generated by the inter-image motion test is made available as an output of the apparatus if its associated test result indicates a greater integrity than the test result obtained by the intra-image similarity test; and the motion vector generated by the inter-image motion test is not made available as an output of the apparatus if its associated test result does not indicate a greater integrity than the test result obtained by the intra-image similarity test.</p> |
