Abstract

A mark reader apparatus has a lens and an autofocus system that manipulates the lens in accordance with control signals. An image acquisition system measures a distance from the lens to a dot peened mark. A processor is programmed to: calculate a focus position for the autofocus system that focuses the lens on the dot peened mark; apply an offset to the calculated focus position to produce an offset focus position; control the autofocus system by positioning the autofocus system to the offset focus position; and via the image acquisition system, acquire an image of the mark with the autofocus system set to the offset focus position.
