ABSTRACT:
A solid state television camera which is free from the noise caused by defects in semiconductor substrate is disclosed. Solid state image sensors derive a plurality of picked up signals. Detectors detect the noise in the picked up signals when the image sensors pick up an image of a reference object, and these detected signals are temporarily stored in a memory which memorizes the noise signals derived by the detectors. Sampling hold circuits which are supplied with the picked up signals are controlled by the memorized signals corresponding to the noise to remove the noise from the picked up signals.
