Imaging system for simultaneous viewing of two images
First Claim
1. An image reproducing system for reproducing two images simultaneously comprising electronic image-reproducing means and optical input means providing optical image information to the reproducing means in which the optical input means includes an optical element having a central region and having a focal length which decreases continuously in the direction outwardly from the central region to provide simultaneous central telephoto and peripheral wide-angle optical image information to the reproducing means.

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.

4. An image reproducing system for reproducing two images simultaneously comprising electronic image-reproducing means and optical input means providing optical image information to the reproducing means in which the optical input means provides simultaneous telephoto and wide-angle optical image information to the reproducing means wherein the optical input means includes two separate lenses having parallel axes to produce two images and corresponding zone filters and mirrors to produce a composite image containing complementary zonal images.
