Abstract:
Infrared light, which is non-readily visible, illuminates at least part of a field of view containing indicia to be electro-optically read. Visible light illuminates another field of view containing the same indicia. The indicia is read by image capture by the illumination light from one of the illuminated fields of view. The use of IR light minimizes an adverse reaction due to only using bright visible light. The use of visible light enables thermally printed indicia, which is not readily readable by IR light, to be read.
