PURPOSE:To reduce the possibility of having defocused photographing by driving a photographing lens by a prescribed length of time when the defocused value of the lens exceeds a previously set defocused value, and after reducing the defocused value, executing shutter releasing operation. CONSTITUTION:A defocused value obtained at the execution of the shutter releasing operation is calculated by a defocused value calculating means and compared with a defocused value previously set up by a comparing means. When the calculated defocused value is <=the previously set defocused value, that the photographing lens is located on a focusing position is decided and the shutter releasing operation is immediately executed. In other cases, the lens is driven by a control means by a prescribed time and then the shutter releasing operation is executed. |
