Abstract
An image pickup system capable of, during flash photography through automatic radiating direction control, quickly starting a next shooting operation when the automatic radiating direction control is suspended. A flash built in or removably mounted on a digital camera has a light-emitting unit that emits light and a drive control unit that changes a radiating direction of light from the light-emitting unit. A preparatory operation for shooting and a shooting operation by the digital camera are disabled while the radiating direction of the light from the light-emitting unit is being changed by the drive control unit. When an instruction to suspend changing the radiating direction of the light is issued, a preparatory operation for shooting and a shooting operation by the digital camera, which have been disabled, are enabled, and the drive control unit is controlled to return the light-emitting unit to an initial position prior to the change.
