摘要： An arrangement for, and a method of, preventing a misread of a one-dimensional symbol that can be read in either one of two polarities in an electro-optical reader. A data capture assembly captures light from the symbol, and generates an electrical signal indicative of the captured light. A controller simultaneously processes and decodes the electrical signal as a first decoded result of one of the polarities and as a second decoded result of the other of the polarities. The controller also determines the validity of the first and second decoded results, and generates an output in dependence upon the validity determination.

摘要： An intelligent gain selection circuit replaces the gain set by an automatic gain control circuit in an electro-optical reader for reading indicia, such as bar code symbols, with a larger gain where specular reflections, high contrast edges, or other noise operative to produce dominant high voltage peaks in an analog signal generated by a sensor in the reader, are detected.

摘要： A target distance to a system target located at variable distances from an imaging system is determined by illuminating a calibration target at a calibration distance with a collimated light beam during a calibration mode of operation, by illuminating the system target at the variable target distance with the collimated light beam during an imaging mode of operation, by configuring the collimated light beam with a beam spot of a generally constant size during both modes of operation, by capturing return light of a calibration image size from the calibration target during the calibration mode, by capturing return light of a target image size from the system target during the imaging mode, and by determining the variable target distance based on the calibration distance, the calibration image size, and the target image size.

摘要： A method and apparatus for setting the amount of exposure for the photodetector array in a barcode scanner. An image is captured with the photodetector array. The type for each sub-region in the multiple sub-regions in the image captured is determined. Each sub-region in the multiple sub-regions is assigned a weight based on the type of the sub-region. The amount of exposure for the photodetector array in the barcode scanner is set automatically based on the weight for each sub-region in the multiple sub-regions. In some embodiments, the predetermined image area are repartitioned into new multiple sub-regions based on the image captured, and the amount of exposure for the photodetector array in the barcode scanner is set automatically based on the weight for each sub-region in the new multiple sub-regions.
