Abstract
A graphical code reader that provides sequenced illumination for glare reduction may include a plurality of light sources that illuminate a target area. The graphical code reader may also include at least one image sensor that captures an image of the target area using a rolling shutter technique. The graphical code reader may also include an illumination controller that sequences illumination of the light sources so that the light sources that are providing the normal component of the illumination to an active portion of the target area are turned off, and so that the light sources that are not providing the normal component of the illumination to the active portion of the target area are turned on.
