Abstract

An image pickup apparatus includes a strobe light emitting unit, a shutter configured to include a front curtain and a rear curtain that control exposure to an image pickup device, at least one processor, and a memory coupled to the processor storing instructions that, when executed by the processor, cause the processor to function as a setting unit that sets a light emission amount of the strobe light emitting unit. The setting unit sets, based on a traveling time of the front curtain, an upper limit value of the light emission amount when performing strobe synchronization photographing at a strobe synchronization maximum shutter speed.
