Claim 8:
9. The electronic device defined in claim 1, wherein the control circuitry comprises: distortion assessment circuitry configured to determine lens module distortion information based at least on the type of the removable lens element that is attached to the lens module; and dynamic geometric distortion compensation circuitry that is configured to compensate the target image for geometric distortion based at least on the lens module distortion information, wherein the distortion assessment circuitry is configured to determine the lens module distortion information based at least on the type of the removable lens element that is attached to the lens module, a position of the removable lens element that is attached to the lens module, and distortion information associated with only the first lens element, wherein the distortion assessment circuitry is configured to perform ray tracing from a first virtual surface between the first and second lens elements to a second virtual surface, wherein the second lens element is interposed between the first and second virtual surfaces, wherein the distortion assessment circuitry includes a database with respective curvature information for a plurality of compatible removable lens elements, wherein the dynamic geometric distortion compensation circuitry is configured to receive the lens module distortion information from the distortion assessment circuitry, and wherein the dynamic geometric distortion compensation circuitry is configured to receive viewer eye position information.
