Abstract

A data reader preferably includes an imaging device that operates on a rolling reset basis to capture images of a moving target. Images of moving targets are preferably analyzed to determine the ambient light intensity, and a processor in the data reader preferably adjusts operation of the imager and of a light source based on the intensity of the ambient light. Other data readers may use an imager with a mechanical shutter that is designed for rapid, frequent operation.

Description

[0001] related application [0002] This application claims priority to U.S. Provisional Application 61 / 145,729 entitled "Systems and Methods for Imaging," filed January 19, 2009, under § 119(e) § 35, United States Code, and claims Priority to U.S. Provisional Application 61 / 140,930, entitled "Optical Code Reader Having Compact Arrangement for Acquisition of Multiple Views of an Object," entitled "Optical Code Reader Having Compact Arrangement for Acquisition of Multiple Views of an Object," both of which are hereby incorporated by reference in their entirety. technical field [0003] The field of the invention relates to data acquisition and decoding systems and devices using imagers. Background technique [0004] Solid-state imagers used in data readers, such as hand-held and fixed-mount optical code readers (such as barcode readers), can be used to obtain images of moving objects, that is, where the object is moving relative to the imager or The imager moves relative to ...
