To solve the following problem; in a focus control system in conventional technology, in addition to an image processing of a television camera, it is necessary to perform an image processing for a focus control, then, to reduce the circuit scale of the autofocus control system by using a contour signal detected for performing the contour correction of the image in the television camera image processing as a focus control signal.

In the television camera system with an image contour detecting function, the television camera includes an integrating means for integrating the contour signal outputted from the contour detecting function for every field or every frame.
