摘要： Systems and methods of optical code reading include production of image data by a color image sensor array (102) and processing of the image data to decode an optical code (112). In one configuration, the color image sensor array includes first and second sets of sensor pixels (204, 206, and/or 208) sensitive to light having wavelengths within, respectively, first and second wavelength bands, reflected light is focused by an optical system (104) to form an image of an optical code on the color image sensor array, first and second sets of image data representing light intensity levels sensed by, respectively, the first and second sets of sensor pixels are produced, and the first set of image data is processed to determine whether the second set of image data is to be used in combination with the first set of image data to decode the optical code.
