Abstract
A method is disclosed as including scanning a first pixel of an image with a primary scanning line of a sensor, and scanning a second pixel of the image with a secondary scanning line of the sensor, wherein the first pixel is separated from the second pixel by a pitch of one or more scan lines. A compensation value is determined for one or more pixels of the image, wherein the compensation value is determined based, at least in part, on a mathematical operation comprising pixel values associated with the first and second pixels and the pitch. The method further includes compensating the one or more pixel values based, at least in part, on the compensation value, wherein the compensation value compensates for a reflection of light between the first and second scanning lines when the first and second pixels are scanned.
