Abstract
Methods and systems for auto-tuning a handheld scanning device that can account for changes in the orientation between the handheld scanning device and a presented symbol can include capturing a first image containing a presented symbol, recording an orientation parameter and parameters associated with capturing the first image containing the presented symbol, capturing a subsequent image containing the presented symbol, recording an orientation parameter of the presented symbol contained in the subsequent image, comparing the orientation parameter of the symbol contained in the subsequent images to the orientation parameter of the presented symbol contained in the subsequent image, determining if the orientation parameter of the presented symbol contained in the subsequent images is substantially similar to the orientation parameter of the symbol contained in the first image, and recording parameters associated with capturing the subsequent images containing the presented symbol.
