摘要： A video motion detection apparatus includes a mechanism applying a motion test by comparing test areas of an image with respective sets of candidate areas in that or another image and generating motion vectors in dependence on a displacement between each test area and a candidate area giving a greatest similarity between the test area and that candidate area; and a mechanism applying an integrity test to test the motion vectors. For a motion vector failing the integrity test, the corresponding test area is divided into two or more smaller test areas and the motion test is applied again in respect of the two or more smaller areas, and a motion vector passing the integrity test is made available as an output of the apparatus.

摘要： An image processing apparatus in which output pixels of an output image are generated from one or more input images using motion vectors having a sub-pixel accuracy. A motion vector allocator allocates motion vectors in the pixels, and compares a current output pixel with test image areas pointed to by motion vectors in the pixels to detect a most suitable motion vector for the current output pixel. A pixel generator operates in a first mode if the output pixel is within a threshold displacement from an image region having substantially different motion characteristics to those of that output pixel, and in a second mode otherwise. The pixel generator includes a spatial filter generating an output pixel value at a required pixel position to a sub-pixel accuracy.

摘要： A video processing apparatus in which at least a subset of output pixels of an output image are generated from one or more input images using motion vectors having a sub-pixel accuracy. A band filter derives lower and higher spatial frequency portions from the one or more input images. A lower frequency contribution relating to a pixel position nearest a required output pixel position from the lower spatial frequency portion is derived using a respective motion vector. A higher frequency contribution from the higher spatial frequency portion is derived using the respective motion vector. A spatial filter generates, from one or more of the higher frequency contributions, a higher frequency pixel value at the required pixel position. A combiner combines the lower frequency contribution and the higher frequency pixel value to generate an output pixel value relating to the required pixel position.

摘要： A video motion detection apparatus generating successive output video signal messages based on input video signal images. The apparatus applies a motion test detecting inter-image motion between two or more input video signal images, providing two sets of one or more motion vectors used for generating respective output image generating test output images using the respective motion vector sets, and compares image areas in the test output images pointed to by the motion vectors in one or both sets. For a motion vector with less than a predetermined degree of similarity between the image areas, the image areas are divided into two or more smaller image areas and the comparison is applied to each of the smaller areas. The use of motion vectors is inhibited for image areas in the test output images that have less than a predetermined degree of similarity at the image area sizes tested.
