Claim:
1. An apparatus for processing products associated with targets to be read by image capture, comprising: a housing; a window supported by the housing; a solid-state imager supported by the housing and having an array of image sensors looking at a field of view that extends through the window to a target to be imaged; a proximity system supported by the housing and operative to detect a product associated with the target in a selected zone, the proximity system having an infrared (IR) emitter to emit IR light into an IR emission field, and an IR sensor to sense return IR light within an IR detection field that is different from the field of view looked by the solid-state imager to image the target, wherein the IR detection field intersects the IR emission field to form the selected zone that separates from the IR sensor with distal end thereof defined by a side boundary of the IR emission field and with proximal end thereof defined by another side boundary of the IR emission field, the selected zone further separating from the IR emitter with far end thereof defined by a side boundary of the IR detection field and with near end thereof defined by another side boundary of the IR detection field, and at least three corners of the selected zone being in front of the window; an energizable illumination system supported by the housing and operative to illuminate the field of view with illumination light over an illumination field; and a controller operatively connected to the imager, the illumination system and the proximity system, to energize the illumination system in response to detection of the product in the selected zone by the IR sensor in the proximity system, and to process return illumination light returned from the target and captured in the field of view by the imager.
