撮像装置およびその制御方法
Document Type and Number:
Japanese Patent JP5489591
Kind Code:
B2
Abstract:
An imaging apparatus includes a light metering unit, a setting unit configured to set an exposure condition including exposure time and an aperture value at a time of flash photography based on a result of light metering by the light metering unit, and a first calculation unit configured to calculate an amount of light emission by a light emission unit to perform flash photography under the set exposure condition based on the result of light metering, wherein, when a first amount of light emission to perform flash photography under a first exposure condition is larger than a maximum amount of light emission that can be achieved by the light emission unit, the setting unit sets a second exposure condition having shorter exposure time and a smaller aperture value than the first exposure condition, and the first calculation unit calculates a second amount of light emission smaller than the maximum amount of light emission.
