Abstract: Photographic system and apparatus in the form of a highly automated reflex camera is described. The camera incorporates a multi-gate control circuit operating the components thereof through the operational phases in the course of a single photographic cycle. In the course of each such cycle, phase changes are monitored by transducers acting as an electrical-mechanical interface within the system. The camera also features an automatic circuit reset operation in the event of a cycle malfunction.

Abstract: An exposure control system for photographic apparatus which functions automatically to regulate both exposure apertures and exposure interval. The system is operable under an exposure program wherein over a select range of light levels, aperture area is varied with respect to scene light values in a relationship less than 1:1. The system provides for sequential regulation first of aperture, then of exposure interval. Voltage-sensitive triggering circuits are used for controlling the apertures and shutter mechanisms. These circuits are coupled to receive the output of a light-sensitive circuit and are arranged in series with a power source to develop a voltage reference level for use with differential amplification stages within the system. The system is calibrated or accommodating varying sensitometric characteristics of films through the use of a gain control in connection with an amplification stage. The system is capable of operating under a predetermined exposure program through the use, inter alia, of an aperture control arrangement which functionally relates aperture blade dynamics, the output of a photosensing circuit and the signal of a function generator.
