Abstract
A flash control device repeatedly informs a firing timing during an exposure period of the image capture apparatus. The device stops informing the firing timing if a condition for ending the exposure period of an image capture apparatus is satisfied. The disclosed flash control device can control the firing timing even in a case where a shooting mode of the image capture apparatus is a shooting mode with an indefinite exposure period.
