Zusammenfassung:	A flash unit capable of being attached to a flash control unit, comprising: a memory that stores information relating to a light emission time for actual flash corresponding to a difference between an emitted light amount command value for actual flash and an emitted light amount command value for pre-flash, and a controller, including an light emission time calculation section that obtains light emission time corresponding to emitted light amount command value for actual flash based on emitted light amount command value for pre-flash, emitted light amount command value for actual flash, and information stored in the memory, wherein the controller inputs the emitted light amount command value for pre-flash and the emitted light amount command value for actual flash acquired to the light emission time calculation section, and controls actual flash of the flash light emitting source based on the light emission time.
