Illumination device capable of having optical accessory attached forward of light emission section thereof, image pickup system, film holder, light emission control device, and light emission control method

摘要

Light emission control makes it possible to determine an appropriate main light emission amount even when an optical accessory that changes color characteristics of transmitted light is attached forward of a light emission section of an illumination device. A strobe capable of having a color filter attached thereto, which changes color characteristics of transmitted light. The strobe includes a strobe microcomputer that acquires information on characteristics of the color filter attached forward of the light emission section, and transmits the acquired information on the characteristics to an image pickup apparatus on which the strobe is mounted.
