Abstract

For simultaneous viewing, for example, of a stretch of roadway in front of a vehicle, with telephoto and wide-angle images, an electronic receiver receives telephoto and wide-angle image information from an input optical system. In one example, a telephoto lens and a wide-angle lens have individual zone filters whose transmissive regions are complementary to each other. The zone images are combined into a composite image for reproduction by the receiver.
