Abstract
A method for glare reduction may be implemented by a graphical code reader. The method may include illuminating a target area using a plurality of light sources. The method may also include capturing images of the target area using at least one image sensor that operates in accordance with a rolling shutter technique. The method may also include determining that glare is present in at least one captured image. The method may also include determining which of the light sources are responsible for the glare. The method may further include taking corrective action to reduce the glare in subsequent images based on which of the light sources are responsible for the glare.
