A solid state television camera having a solid state image sensing device, such as CCD image sensing device and an iris for controlling the amount of light from an image irradiated on the image sensing device. The iris is controlled by the peak level of a smear signal of a horizontal scanning line during a vertical blanking interval so that the smear signal contained in a video signal from the image sensing device is reduced. Further, the iris can be controlled by the average level of the smear signal instead of the average level of the video signal of one field as the smear signal has the whole information of the image of one field, that causes the construction of detecting circuit to be very simple and the fidelity of the iris control to be high.
