Abstract
Continuous photography control for a camera wherein an autofocus system is provided, and a motor is used commonly to move a taking lens for focusing and to open and close a shutter for exposure. When a mode switch is operated to set a continuous photography mode wherein plural exposures are continuously performed, the motor is driven to move the taking lens from an initial position into an in-focus position that is determined by the autofocus system and, thereafter, to open and close the shutter a selected number of times while maintaining the taking lens in the in-focus position. The taking lens is returned to the initial position after the selected number of exposures are performed. Alternatively, when another mode switch is operated to set a photography mode wherein only a single exposure is performed per one depression of the shutter button, then the taking lens is moved from the initial position to the in-focus position; the shutter is opened and closed only once; and then the taking lens is moved back to the initial position.
