Abstract
An optical code scanner is presented that includes image capture technology to read optical codes. The optical code scanner captures an image of an optical code and then generates multiple reduced resolution versions of the image. Multiple techniques are applied to the different images to identify a region of interest, enhance the contrast of the image, perform a non-linear local geometrical distortion correction and minimize the spatial resolution required to read the optical code. The techniques reduce the raw processing power and time required to identify and read an optical code.
