    Abstract: An optical code reader (12) is provided including imaging circuitry (10) having an array (106) of photo sensing devices (200) capable of sensing ligh t incident on the array and outputting a plurality of pixel signals (502) corresponding to the sensed light. The reader further includes control and logic circuitry for receiving a subset of the plurality of pixel signals, processing the received subset of the plurality of pixel signals for determining if the received pixel signals meet at least one predetermined condition, and outputting a selection control signal in accordance with the processing results. A focus analysis software module executable by the contr ol and logic circuitry determines the focus quality of the received pixel signals. A selector control software module executable by the control and logic circuitry generates a selection control signal in accordance with the determined focus quality of the received pixel signals. Selector circuitry selectively enables the imaging circuitry to output selected pixel signals o f the plurality of pixel signals in accordance with the selection control sign al.

    Abstract: A system and method are provided for performing a read operation including acquiring a series of frames of image data; processing a first frame of image data including an array of pixel data acquired while an aiming pattern (204) was generated for determining a location L (206a) of at least one pixel of the array of pixel data that corresponds to the aiming pattern; and processing a second frame of image data acquired while the aiming pattern (204) was not generated. The processing of the second frame of image data includes the steps of selecting at least one optical code acquired in the second frame of image data that is located at a respective location; wherein the respective location meets a predetermined condition relative to the determined location L (206a); and providing the selected at least one optical code for further processing in accordance with the read operation.
