摘要： A charge-coupled device (CCD) camera with a smear reducer circuit is disclosed, which includes a CCD for generating a pickup signal, a memory for storing an extracted smear signal from the pickup signal and, a level selector circuit for cutting off a noise contained in the smear signal with level less than a predetermined level in the smear signals from the memory. The output of this level selector circuit is subtracted from the pickup signal to thereby obtain a pickup signal with the smear reduced as well as a noise component suppressed.

摘要： 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.
