Abstract
An automatic adjustment system for a camera which time division multiplexes inputs from a scanning system, and an automatic exposure control or a film feeding motor speed control into an evaluation circuit. The same electronic circuitry is thereby used for evaluating the input from any of the mentioned adjusting systems to minimize the complexity and bulk of the camera circuitry necessary for processing. Each aforementioned automatic feature compares a respective pair of signals to determine the respective adjustment. A pair of signals is brought to a common condition indicative of proper adjustment by use of feedback from the actual state of the automatic system for the particular feature.
