Abstract: A method, comprising: providing a first border array associated with a first block, the first border array comprising several elements, wherein the value of each element corresponds to the sum of signal values of pixels enclosed within an integration region within said first block, providing a second border array associated with a second block, the second border array comprising several elements, wherein the value of each element corresponds to the sum of signal values of pixels enclosed within an integration region within said second block, determining a first representative element from the first border array according to a calculation point, determining a second representative element from the second border array according to said calculation point, and calculating a sum of signal values of pixels located within a summation region by using the first representative element and the second representative element, said summation region having a corner at said calculation point.
