Abstract
A decodable indicia reading terminal can comprise a housing including a housing window, a multiple pixel image sensor disposed within the housing, an imaging lens configured to focus an image of decodable indicia on the image sensor, an optical bandpass filter disposed in an optical path of light incident on the image sensor, an analog-to-digital (A/D) converter configured to convert an analog signal read out of the image sensor into a digital signal representative of the analog signal, and processor configured to output a decoded message data corresponding to the decodable indicia by processing the digital signal.
