Abstract
An image sensor array for capturing a sequence of video frames has a plurality of pixels, wherein each one of the pixels has a set of intrapixel logic including a previous register to store a pixel value of a previous frame and a current register to store a pixel value of a current frame, the current registers corresponding to the previous registers. An intrapixel subtractor coupled to the previous and current registers produces a difference between the previous and current registers for all pixels in the video frames in parallel. The differences are accumulated for each block of the image sensor array to form a total divergence for each block. The total divergences, associated motion vectors, and pixel values are used in motion estimation processing by a processor coupled to the image sensor array.
