    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: An image of a target in a far-field range of working distances relative to an image capture system is focused at a first group of sensors in a common, two-dimensional, array of sensors (12), and an image of an optical code in a near-field range of working distances relative to the system is focused at a second group of sensors in the array. The same array is shared in a portable apparatus capable of capturing target images and optical code images without moving any optical components. The apparatus includes an images sensor board (14) carrying the array (12) and lens assembly (22) mounted on a first chassis member (24). A seconds chassis member (26), together with the first chassis member, forms a rigid body for the image engine.
