1. A integrated circuit chip for capturing and processing images, comprising: imaging circuitry for capturing an image projected thereon and for generating an analog signal representative thereof; conversion circuitry for converting the analog signal to a corresponding digital signal; correlation circuitry for processing the digital signal to generate a result surface on which a minima resides, the minima representing a best fit image displacement between the captured image and previous ones thereof; and interface circuitry for formatting the digital signal so as to be compatible for signal communication with a preselected device.
