Abstract
Performing optical mark recognition (OMR) scanning includes receiving a substrate to be scanned, the substrate having one or more colors visible to a human eye and bearing user-made marks; moving the substrate and a light sensor relative to each other such that the substrate moves past the light sensor a single time; during the relative movement of the substrate, scanning the substrate using multiple colors of light to simultaneously generate both (a) image data representing a visual appearance of the substrate, and (b) OMR data corresponding to respective locations of the user-made marks on the substrate.
