Zusammenfassung:	With a pre-light emission quantity adjusted to an appropriate value, the accuracy of light control for main light emission can be enhanced. A first pre-light emission quantity is obtained with no use of distance information. An appropriate light emission quantity is obtained with use of distance information, and a second pre-light emission quantity is obtained by decreasing the appropriate light emission quantity by a predetermined quantity according to a photometric wave detection capacity. A final pre-light emission quantity is obtained by mixing the first pre-light emission quantity and the second pre-light emission quantity, at a ratio corresponding to the accuracy of the distance information used to obtain the appropriate light emission quantity.
