Abstract (en)
[origin: WO0051064A1] A method for monitoring a field of view (14) for visible changes is disclosed. A first image is taken in a predetermined manner of the field of view to be monitored, and then an array divides the first image into a plurality of cells (36). A second image is taken in the predetermined manner of the field of view to be monitored. The array is also applied to the second image, dividing the second image (38) into the plurality of cells. Predetermined groups of cells of the second image are then compared to the same groups of cells of the first image, and the number of the groups of cells that changed from the first image to the second image is computed. In some situations only certain groups of cells are compared.
