Abstract

PURPOSE: To avoid the shift in the white balance even if the iris of lens is changed, by correcting the white valance through the control of output level of BPF with the lens iris control signal by means of the gain control circuit.
CONSTITUTION: The pick up tube 2 modulates optically the color component with the stripe filter and the camera lens 1 is placed in front of the pick up tube 2. The amplifying and detecting circuit 12 amplifies and detects the modulation amplifing signal, and the iris opening of the lens 1 is automatically controlled with the lens iris control signal of the output, and the gain control circuit 13 controls the output level of BPF 5 with the lens iris control signal to correct the white balance. Thus, even if the lens iris is changed, the white balance can be avoided from being shifted.
