Claim 11:
12. A method of operating a code reader, the method comprising:
determining a target distance of an object;
selecting and activating a first imager and a first illuminator as a receiver pair of an optical code reader with a second illuminator not active, responsive to the target distance being less than a first distance threshold indicative of the object being in a near field of the code reader;
selecting and activating a second imager and a second illuminator as a receiver pair of the optical code reader with the first illuminator not active, responsive to the target distance being greater than a second distance threshold indicative of the object being in a far field of the code reader, wherein the first imager has a near field of view and the second imager has a far field of view, wherein the first illuminator and the second illuminator project a different pattern visible to a user and that has substantially matching dimensions of the corresponding field of view for its receiver pair, such that the respective illumination pattern that is visually presented to the user changes its shape depending on which imager is selected as the active imager; and
decoding an optical code using an image captured by the selected receiver pair.
