Filed: 1981-11-27
Abstract: PURPOSE:To detect an optimum focus without using a photoelectric conversion element for focus information detection, by obtaining a point where the signal level of a high frequency component in a video signal is maximum, and positioning the focus. CONSTITUTION:A signal E30 including a high frequency component is picked up from a video signal E16 of a TV camera 20, an output signal E34 of a VCO34 is superimposed and a signal E32 having the frequency distribution corresponding to the frequency sum is formed. A signal E52 corresponding to an envelope of the signal E32 is formed and picked up via sample hold circuit 68 by taking the peak level as a signal E68. In a sample hold circuit 70, the level of the signal 68 when the signal E32 reaches a maximum frequency, is picked up as a signal E70. This signal E70 indicates the peak level of the maximum frequency  component of the signal E30.
