Abstract:
A ranging apparatus including an image sensor, an imaging lens, and a processor is provided. The imaging lens is configured to image an object on the image sensor to produce an image signal having at least one image parameter, wherein the at least one image parameter changes with a change of an object distance of the object. The processor is configured to determine the change of the object distance according to a change of the at least one image parameter. A ranging method and an interactive display system are also provided.
