撮像装置、及びその制御方法
Document Type and Number:
Japanese Patent JP6910881
Kind Code:
B2
Abstract:
An image pickup apparatus capable of ensuring the accuracy of a proper main light emission amount. A flash device can change an emission color temperature by changing a ratio of light emission between light sources different in emission color temperature. A photometry unit measures a luminance of light reflected from an object by preliminary light emission of the flash device. It is selected whether to perform second preliminary light emission at a color temperature changed according to at least one of spectral characteristics information of the light source, shooting condition information, and photometric value information obtained by first preliminary light emission, and determine a main light emission amount based on a photometric result obtained by second preliminary light emission, or to determine the main light emission amount based on a photometric result obtained by first preliminary light emission without performing second preliminary light emission.
