A method of decoding a color barcode involves simultaneously illuminating the color barcode with three light zones in a manner that illuminates each bar of the color barcode with each of the three spatially separated light zones, where the three light zones are each illuminated by a different one of three colors; capturing a monochrome image of light reflected off of the color barcode that includes each of the bars in the barcode illuminated by the three light zones; and for each bar in the color barcode, determining a color of the bar by analysis of the intensity of the light captured in the image of the reflected light intensity in each of the three light zones.

An imaging scanner is provided. The image scanner has a housing. The housing contains a mirror, a camera, a transparent window for scanning, a transparent window for viewing positioned above the transparent window for scanning such that anything presented below the transparent window for scanning is visible in the transparent window for viewing. The transparent window for viewing has an electronic display embedded therein. The imaging scanner also includes an image decoder linked to the camera and to the electronic display. The mirror is positioned such that incident light on the mirror from the transparent scanning window will be reflected within the camera's field of view. The camera is configured to scan images presented at the transparent window for scanning. The image decoder is configured to decode the scanned images. The electronic display is configured to display the decoded information on the transparent window for viewing.

Method of and system for reading bar code symbols using a hand-supportable laser scanning bar code symbol reading system supporting an improved level control over the length of laser scan lines projected onto scanned objects, at any instant in time, in a manner dependent the detected location, distance or range of the scanned object in the scanning field of the system during system operation. The length characteristics of the laser scan line are controlled by setting the laser scan sweep angle as a function of detected or estimated distance or range of the object from the system. In the illustrative embodiment, the laser scan sweep angle is controlled by supplying a drive current to the scanning mechanism, as a function of detected or estimated distance or range of the object from the scanning system.
