Abstract
A data-reading image capture apparatus, camera, and method of use. The capture apparatus has a digital image detector sensitive to a band of visible radiation and a band of invisible electromagnetic radiation. An optical system, in the capture apparatus, focuses the bands of electromagnetic radiation on the image detector. An image separator is disposed in the capture apparatus, in operative relation to the digital image detector and optical system. The image separator is switchable between an image capture state and a data reading state. The image separator is attenuative for the band of invisible radiation and transmissive for the band of visible radiation in the image capture state. The image separator is attenuative for the band of visible radiation and transmissive for the band of invisible radiation in the data reading state.
