HIGH-RESOLUTION OPTICAL CODE IMAGING USING A COLOR IMAGER

摘要

An optical code or other data reading device (100) includes a color image sensor array (102) positioned to sense light reflected from an object (114), and to produce image data. In one configuration, the sensor array has multiple sets (e.g., first set (104) and second set (106)) 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 (108) is positioned to illuminate the field of view (116) with light that is reflected off the object toward the 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.
