Abstract:
A method for determining a pixel value for each of a plurality of pixels corresponding to an object, the method comprising the steps of:determining a plurality of sampled values associated with each pixel corresponding to the object,determining an accumulated value of each pixel based on the plurality of sampled values associated with each pixel, andstoring the accumulated value of each pixel as a first portion in a first memory area, and a second portion of the same accumulated value in a second memory area, the first and second memory areas having a plurality of memory locations for containing the first and second portions of the accumulated value of each pixel, respectively, wherein the accumulated value of each pixel includes M bits,the first portion includes M-N most significant bits of the accumulated value andthe second portion includes N least significant bits of the accumulated value; andthe plurality of sampled values associated with each pixel is equal to 2 N.
