Image pickup apparatus and controlling method therefor |
摘要 |
An image pickup apparatus that is capable of reducing variation in the color temperature of a subject in a taken image and capable of shooting a more suitable image. The image pickup apparatus can shoot with emitting a light emitting unit. A color temperature acquisition unit acquires information about a color temperature of a light illuminating a subject. An emission control unit controls emission of the light emitting unit. The emission control unit determines emission light amount of the light emitting unit based on a color temperature difference between a color temperature of an illumination light of the light emitting unit and a color temperature based on the information acquired by the color temperature information acquisition unit. |

1. An image pickup apparatus that is possible to shoot with emitting light by a light emitting unit, a color temperature of the emitted light by the light emitting unit being fixed, the apparatus comprising:
a color information acquisition unit configured to acquire color information related to a light illuminating a subject; and an emission control unit configured to control emission of the light emitting unit, wherein the emission control unit determines emission light amount of the light emitting unit based on a difference between predetermined color information and color information acquired in a case where the light emitting unit does not emit the light by the color information acquisition unit. |
