Abstract:
An optical reading apparatus for reading image information selected from a group consisting of optical codes, one-dimensional symbologies, two-dimensional symbologies and three-dimensional symbologies, said image information being contained within a target image field, said optical reading apparatus comprising:a light source projecting light onto said target image field;an optical assembly comprising at least one lens, said optical assembly focusing said light reflected from said target field;a sensor, said sensor including a plurality of pixel elements for sensing an illumination level of said focused reflected light;an optical processor generating an electrical signal proportional to said illumination level received from said sensor and converting said electrical signal into output data, said output data describing at least one value for each pixel element;a memory receiving and storing the output data, the stored output data indicative of the target image field;an image processor receiving a portion of the output data and generating distinguishing data from an identified area of interest; anda data processing unit coupled with said memory and responsive to the distinguishing data, the data processing unit including processing circuits processing the stored data to produce decoded data representing said image information.
