Abstract:
1. A decodable indicia reading terminal comprising: a housing including a housing window; a multiple pixel image sensor disposed within said housing; an imaging lens configured to focus an image of decodable indicia on said image sensor; an optical bandpass filter disposed in an optical path of light incident on said multiple pixel image sensor, said optical bandpass filter configured so that light incident on each pixel of said multiple pixel image sensor passes through said optical bandpass filter and is subject to bandpass filtering by said optical bandpass filter in common wavelength ranges, said optical bandpass filter configured to pass light of two or more selected ranges of wavelengths and to attenuate light of wavelengths outside of said two or more selected ranges of wavelengths; an analog-to-digital (ND) converter configured to convert an analog signal read out of said image sensor into a digital signal representative of said analog signal, said analog signal representative of light incident on said image sensor; and a processor configured to output a decoded message data corresponding to said decodable indicia by processing said digital signal.
