Estimating the term…
A light-emitting apparatus which capable of preventing the perfect moment to take a photograph from being missed while reducing draining of a charging unit caused by charging thereof. In accordance with an instruction from a camera 100, a flash MPU of an external flash 120 switches to perform one of a first charging control and a second charging control in accordance with a first instruction from the camera 100. The first charging control charges the charging unit 202 until a charging voltage thereof reaches a target first level and then maintains the charging level at the first level, and the second charging control charges said charging unit 202 until the charging voltage reaches the first level when the charging voltage reaches a second level lower than the first level.
A light-emitting apparatus comprising:
A charging control method for a light-emitting apparatus comprising a light-emitter, and a charging unit that has a capacitor and is charged with electrical charge for causing the light-emitter to emit light, comprising:
A non-transitory computer-readable storage medium storing a program for causing a computer to execute a charging control method for a light-emitting apparatus comprising a light-emitter, and a charging unit that has a capacitor and is charged with electrical charge for causing the light-emitter to emit light, the method comprising:
