Disclosed is apparatus for scanning a field of view for two-dimensional data and for rapidly processing the data. There is a video device viewing the field of view and producing a two-dimensional matrix of pixel data as an output representing a plurality of pixel positions of the field of view. A digital memory receives and holds the two-dimensional matrix of pixel data output from the video device in a plurality of multiple pixel data words. There is also a digital processor including a register for receiving pixel data and logic for processing data to decode it. Primarily, there is pixelizer logic and associated circuitry connected between the digital memory and the digital processor for removing data associated with a specified pixel position within the field of view from an associated one of the plurality of multiple pixel data words in the digital memory and for placing the data into a pre-established bit position within the register of the digital processor. The time required to repeatedly obtain the necessary pixels for processing is thereby greatly reduced and minimized.
