Abstract
A method of improving the performance of an imaging reader includes (1) illuminating a symbol by projecting illuminating light on the symbol from the imaging reader, (2) capturing return light form the symbol as pixel data over a two-dimensional field of view of a solid-state imager having a matrix of image sensors, (3) reducing the number of pixels to generate reduced pixel data, (4) transmitting the reduced pixel data to a decoding circuit.
