Abstract:
1. An indicia reading terminal comprising: an image sensor pixel array having a plurality of pixels, the plurality of pixels including a first set of pixels and a second set of pixels, the first set of pixels having wavelength selective filters transmitting light of a first wavelength, the second set of pixels having wavelength selective filters transmitting light of a second wavelength; a hand held housing in which the image sensor pixel array is disposed; an optical imaging assembly for focusing imaging light rays onto the image sensor pixel array, the optical imaging assembly being adapted so that for light rays of the first wavelength the optical imaging assembly has a first focus range and for light rays of the second wavelength the optical imaging assembly has a second focus range; wherein the indicia reading terminal is operative for capture of a frame of image data including image data representing light incident on one or more of the first set of pixels or the second set of pixels; wherein the indicia reading terminal is operative for utilizing image data of the frame representing light incident on one or more of the first set of pixels or the second set of pixels for attempting to decode a decodable indicia; wherein the optical imaging assembly comprises one or more lens and an axially symmetric phase mask.
