Abstract
A camera system employs an electronic imager such as a Charged Couple Device (CCD) or a Complementary Metal Oxide Semiconductor (CMOS) array that captures a first portion of light and reflects a second portion of light reflected from a target subject. The light reflected by the electronic imager may be reflected towards film media or a color filter, for example. The electronic imager may include an integrated circuit, or a dielectric reflecting coating that acts to partially reflect incoming light reflected from the target subject. A display, such as an LCD (Liquid Crystal Display), may be utilized to determine which images are desirable or to identify which films to develop. Film writing circuitry that allows various types of information to be written may be utilized. The camera system further features an electronic imager shutter, and a film shutter for shuttering purposes. The film shutter can provide exposure control. The camera system additionally features a processing or control system that selectively controls using the electronic imager or the film media or both simultaneously. The camera system may also have a beamsplitter such as a prism, mirror or optical coating that tr…
