Abstract
Creating a blur in a digital image by receiving original pixel values in a frame of image data, and for each pixel position in the digital image being blurred, calculating a blurred pixel value by applying a box filter having a plurality of elements with unity multiplier values to original pixel values for pixel positions that include the pixel position and pixel positions that are nearby to it. The output of the first box filter can be sequentially applied as inputs to a second box filter.
