ABSTRACT:
In a solid state television camera for producing output signals corresponding to an object image detected by a solid state image sensor, positions of picture elements having crystal defects and the output signal levels of such defective components are previously stored as the defective picture element data in a memory device. Defect compensating signals corresponding to the actual image pickup operating states are formed on the basis of the defect picture element data read out from the memory device to correct the output signals of such defective picture elements in a manner to provide the image pickup output signals with superior picture quality.
