US Patent 7726574 Method, device and system for scanning optical codes

Apparatuses, methods and systems used to reduce the time needed to process images of a bar code or optical code captured by a image bar code scanner. Image bar code scanners read bar codes or optical codes by capturing digital images of the codes using an image capture device and then processing the captured images to decode the optical code or bar code. The processing time is reduced by rotating the images to align the axis of the codes contained in the captured images with the rows of photo detectors in the image capture device.
