Abstract
An automatic knee control circuit including a knee circuit for setting a knee point and a knee slope, a detecting circuit for detecting an output signal of the knee circuit and a comparing circuit for comparing an output of the detecting circuit with a reference voltage, wherein the knee circuit is controlled on the basis of an output of the comparing circuit. This automatic knee control circuit is characterized by a distributing circuit for distributing the output of the comparing circuit by an arbitrary distributing ratio, wherein the setting of the knee point is controlled by a first distributed output and the setting of the knee slope is controlled by a second distributed output, thereby making it possible to set a wide variety of signal processing states with ease. Therefore, pictures corresponding to cameraman's intention can be produced.
