Abstract
A multi-processing unit reduces the time to compute parameters of a digital image to by the number of computers operating in the parallel. An image of a digital picture taken during a test of a digital camera module is portioned into N independent portions and each portion is stored into one of N memories. N processors compute test parameters of the image, where each processor works independently on a portion of the image and in parallel with the other processors. The serial computational content of the image is zero allowing a speed-up of the multiprocessing unit to be N with respect to the running the entire computation on a single processor.
