Abstract
An optical code or other data reading device includes a color image sensor array positioned to sense light reflected from an object, and to produce image data. In one configuration, the color image sensor array has multiple sets (e.g., first and second sets) of sensor elements that are sensitive to corresponding visible wavelength bands of light (e.g., first and second wavelength bands), the sets also being sensitive to light within an infrared wavelength band. An artificial illumination source is positioned to illuminate the field of view with light that is reflected off an object in the field of view toward the image sensor array, the illumination source being operable to produce infrared light having wavelengths within the infrared wavelength band so that, upon illumination, at least some sensor elements of each of the sets are sensitive to the infrared light and contribute to production of the image data.
