Abstract
A technique that prevents a movable unit of a strobe device including a light emission section from unexpectedly interfering with an obstacle during rotation thereof. The movable unit is supported in a manner rotatable with respect to a device body about a first axis in a vertical direction, and rotatable about a second axis in a lateral direction. In bounce flash shooting, the movable unit irradiates light from the light emission section toward a ceiling to cause reflected light from the ceiling to be irradiated to an object. The movable unit is rotated such that the light emission section is oriented in the optimum irradiating direction. Whether to drive the movable unit in the lateral direction is determined based on a result of determining whether a rotational angle of the movable unit driven in the vertical direction exceeds a predetermined angle.
