A projected image is overlaid on an actual view of an object, the image being identical to the actual view in size, shape and scale, and being perfectly registered with the actual view, e.g, as to position or location, and, accordingly being substantially parallax-free. The image may be of different "color" than the actual view, i.e., one may be a view or image of light in a visible wavelength region, band or bandwidth, and the other may be a view or image in a non-visible wavelength region, band or bandwidth, such as a view or image of infrared light or of x-ray radiation. The infrared view or image may be converted to a view or image in the visible bandwidth for viewing by a person. The image mentioned above may be a real image of an actual view of an object, scene or the like. Alternatively, the image may be an image other than of an actual view of an object, for example being a previously-obtained image along a same or similar point of view as the actual view of the object, scene, or the like. As another example, the image may be a computer-generated image based on previously-obtained data regarding the object, scene, or the like. The image may be an image obtained by a camera or some other means and then delivered, e.g., as by projection via a projector and conjugate optics, for superpositioning with respect to the real or actual view for viewing by a user.
