Abstract:
1. A bar code reading device comprising: a CMOS image sensor array comprising a plurality of pixels in a two-dimensional array, wherein the CMOS image sensor array is operable, in a global shutter mode, to collect image data from a target, wherein, in the global shutter mode, all or substantially all of the plurality of pixels in the CMOS image sensor array are simultaneously exposed in response to an exposure control timing pulse so as to enable the collection of image data in the form of a one dimensional bar code and to enable the collection of image data in the form of a two dimensional bar code; at least one illumination light source configured to illuminate at least a portion of the target in response to an illumination control timing pulse, wherein the exposure control timing pulse and the illumination control timing pulse are coordinated by a control module such that the illumination control timing pulse is transmitted to the at least one illumination light source as a result of the exposure control timing pulse; an autodiscrimination module configured to search the image data collected in the global shutter mode for one or more markers indicative of a presence of at least one of the one dimensional bar code or the two dimensional bar code; and a bar code decoding module that is configured, in an instance in which at least one marker of the one or more markers is detected by the autodiscrimination module, to decode the image data in accordance with a decoding algorithm associated with the at least one marker.
