Abstract

A system and method of determining if a surface contains print or is a screen of a mobile device is provided. The method is comprised of the steps of: acquiring a spectral wavelength signature of the surface; comparing the spectral wavelength signature of the surface to RGB triple-peak emission spectra; scanning the surface with an image-based scanner in non-illumination mode based upon the spectral wavelength signature of the surface corresponding to the RGB triple-peak emission spectra, and scanning the surface with an image-based scanner in illumination mode based upon the spectral wavelength signature of the surface not corresponding to the RGB triple-peak emission spectra.
