Abstract
A versatile graphical code reader that is configured for efficient decoding is disclosed. In an exemplary embodiment, the graphical code reader includes an image sensor. The graphical code reader also includes a region selection component that selects a first region of a digital image obtained from the image sensor. The first region of the digital image corresponds to a same region of the image sensor as a decoded region in a most recently decoded digital image. The graphical code reader also includes a processing component that processes the first region of the digital image before processing any other region of the digital image.
