ABSTRACT:
In a camera having a lens for focussing incident light onto a light reception surface of a pick-up so that the latter outputs a camera signal, a stop for limiting the amount of the incident light, and a variable gain amplifier for correcting the level of the camera signal; there is provided a control circuit which controls a focus of the lens, the stop and a gain of the variable gain amplifier on the basis of the output of the variable gain amplifier, thereby simplifying the construction of the camera as a whole.
