Abstract
Provided is a light emission control apparatus, a light emission control method, a light emission apparatus, and an imaging apparatus that make it possible to emit AF assist light with a more appropriate amount of light. A light emission unit is capable of emitting AF (Auto Focus) assist light when capturing a static image and illumination light when capturing a moving image. A light-amount setting unit sets the amount of AF assist light to a light emission control unit, the light amount being obtained in accordance with a distance to an object to be focused on or specification by a user, and the light emission control unit controls light emission of the AF assist light in accordance with the setting.
