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.

Imaging enhancement for touch cameras

The present invention relates to a method and an apparatus for enhancing the optical image of information-containing symbols captured off reflective surfaces/using a conventional optical scanning camera. The method involves positioning the imaging assembly of the camera atop an information-containing coded symbol located on a component surface, where the imaging assembly includes a diffuser element and LED lighting array for illuminating the symbol, illuminating the surface and the symbol, and moving the diffuser element to a location between the coded symbol and the camera lens such that only light returning directly from the symbol is able to pass through the voided region of the diffuser element, before imaging the coded element.
