ABSTRACT:
A mode discriminating device for an image signal processing system for discriminating between various operating modes of the image signal processing system. The mode discriminating device includes a microcomputer, a cam switch having a connecting element, and a voltage divider having an output terminal coupled to an input of the microcomputer. The voltage divider is composed of impedance elements and connecting taps, and is arranged at a position opposed to the connecting element. The connecting element makes simultaneous contact with the one of connecting taps and the output terminal according to the rotation of the cam switch. The output terminal supplies a corresponding voltage to the microcomputer which, by comparing the output voltage to reference data, discriminates between various operating modes of the system.
