Title: Automatic focus device
Inventor: MIYAKE MAKOTO
IPC: G02B7/28
Filed: 1991-11-25
Abstract: PURPOSE:To prevent undesired movement of a focus lens when a focus evaluation value is changed regardless of a focusing state. CONSTITUTION:A level of a prescribed frequency band component included in a luminance signal is detected by a detection circuit 16 and sampled at a sampling circuit 24. A maximum value of the sampled level is held by a peak hold circuit 22 and the sampling values for a period are integrated by an integration circuit 23. So long as the peak level held in the peak hold circuit 22 is not changed, a focus control means is set to a state when the integration value integrated by the integration circuit 23 is a maximum value.
