Abstract
When the depth information indicating a difference among a plurality of subjects in the size of subject distance is large, an imaging apparatus lowers a threshold value of the subject luminance to be referred to when determining whether to perform a shooting operation with light emission by an illumination device.
Claims14
An imaging apparatus that can perform a shooting operation with an illumination device, comprising:
- a light metering unit configured to measure a subject luminance;
- an acquisition unit configured to acquire information relating to subject distances of a plurality of areas;
- and
- a light emission control unit configured to cause the illumination device to emit light in a shooting operation if the subject luminance measured by the light metering unit is less than a threshold value,
- wherein the light emission control unit is configured to change the threshold value according to a difference among the plurality of areas in subject distance based on the information acquired by the acquisition unit.
