Abstract
The present invention relates to a method and an apparatus for enhancing the optical image of information-containing symbols captured off highly reflective surfaces using a conventional optical touch camera. The method involves positioning the imaging assembly of the touch camera atop an information-containing coded symbol located on a component surface, positioning a diffuser element between the coded symbol and the imaging assembly, and moving the diffuser element into juxtaposition with the coded symbol before imaging the coded element.
