PURPOSE:To prevent an out-of-focus photograph from being taken by quitting forecasting a moving body when at least one time differences between information for focus adjustment and current time is larger than a predetermined time difference. CONSTITUTION:A battery is connected to a CPU 2, a range finding circuit 3, a light measuring circuit 4, a focusing display circuit 5, a range display circuit 6, and an E<2>PROM 7 and supplies electric power. The CPU 2 is a one-chip microcomputer and controls all sequences of the camera. Further, a timer function which measures range finding time and measures a wait time in self-timer photography is provided and a RAM 5 is temporarily stored with necessary data such as the range-found value and range finding time. The input times of plural pieces of information for focus adjustment are stored and the time difference between the stored pieces of information for focus adjustment and current time are calculated; when at least one of the calculated time differences is larger than the predetermined time difference, the forecasting of the moving body is quitted. |
