Patent ID: 8638479

Claim:
An improved method for operating a scanning device to reduce environmentally-induced noise including glare noise, dirt noise, and ink noise, the method comprising: positioning an object on a platen within a scan area in proximity of a plurality of scanner lights and an optical element, wherein the optical element comprises a camera configured to capture an image of the object, and wherein the scanner lights are spaced along the scan area; activating a first subset of the plurality of scanner lights; controlling the optical element to scan a first portion of the object within a first limited region of the scan area while the first subset of scanner lights are activated, said first limited region of the scan area defined so as not to create a direct reflection to the optical element of light from the first subset of scanner lights; deactivating the first subset of the plurality of scanner lights; activating a second subset of the plurality of scanner lights; and controlling the optical element to scan a second portion of the object within a second different limited region of the scan area while the second subset of scanner lights are activated, said second limited region of the scan area defined so as not to create a direct reflection to the optical element from the second subset of scanner lights.
