ABSTRACT:
A camera with a built-in self-timer, flash and autofocus is disclosed. The camera is switchable between normal and self-timer modes. When in the normal mode, the auto focus device measures distance at the beginning of a photographic cycle. In self-timer mode, the auto focus device measures the distance at the beginning of the photographic cycle, and after the self-timer has counted down from its set time. A decision to use the flash is based on the first distance measurement and the scene brightness in the normal mode, and on the second distance measurement and scene brightness in the self-timer mode. If the decision is yes, a checking apparatus checks whether the flash capacitor has sufficient charge, and if not charges the capacitor.
