A focus detection signal is generated from the video signal produced by a video camera by deriving higher frequency components of that video signal, detecting when those higher frequency components exceed a minimum threshold level, sensing when the video signal exceeds a maximum threshold, and integrating those higher frequency components which exceed the minimum threshold, except during an interval when the video signal exceeds the maximum threshold, thereby producing the focus detection signal.
