ABSTRACT:
A small scale gain control circuit for controlling gain correction quantity is realized, using the configuration of an inverter, a subtraction circuit, a limiter, and a multiplication circuit. Gain correction quantity is controlled in such a way that in the gradation correcting apparatus a first constant fixes a value beyond which gain correction quantity is zero and a second constant fixes an inclination of the characteristics line.
