摘要： Disclosed are embodiments of methods, systems, and apparatus for providing virtual scan lines in an imaging system that compensate for the optical distortion associated with the system. In some embodiments, the virtual scan lines may be curved or angled according to their position in the Field of View (FOV) of the imaging system to compensate for the distortion. Some embodiments may provide for virtual scan lines that are preconfigured to compensate for a typical or pre-selected level and type of optical distortion. Other embodiments may be configured to measure or otherwise ascertain the actual distortion of the optical lens and/or other components of the system and generate a virtual scan line pattern that compensates for the measured distortion.

摘要： Systems and methods for decoding a barcode or other optical code include identifying one or more sub-regions of image data that contain promising data based on a first set of edge detection parameters, transferring the promising data from a first memory location to a new memory location for further processing, and decoding the promising data based on a different set of edge detection parameters.
