Image pickup apparatus that reduces time required for light control processing and method of controlling same
An image pickup apparatus that performs, when photographing an object, photographing by causing a light emission device to emit light to the object. A photometry sensor selectively obtains a first image having a first resolution and a second image having a second resolution lower than the first resolution, as a photometric image, and performs photometry using the obtained photometric image to thereby obtain a result of photometry. When performing light control processing for determining a main light emission amount for causing the light emission device to perform main light emission for photographing the object, the light control is switched between first control for performing light control processing based on the first image and second control for performing light control processing based on the second image, according to a result of determination of whether or not a predetermined condition is satisfied.
Imaging apparatus, method for controlling imaging apparatus, and processing apparatus
To increase the accuracy of adjusting the main light emission. An amount of main light emission is adjusted on the basis of an estimated pre-light-emitted subject distance or information corresponding to the estimated pre-light-emitted subject distance and an estimated lens-focused subject distance. The estimated pre-light-emitted subject distance and the information corresponding to the estimated pre-light-emitted subject distance are obtained by pre-light-emission processing. The estimated lens-focused subject distance is obtained from focus information through a lens. In a case of bounce light emission, in a case where the estimated pre-light-emitted subject distance is smaller than the estimated lens-focused subject distance, a distance made closer to the estimated lens-focused subject distance from the estimated pre-light-emitted subject distance by a predetermined amount is set as an estimated subject distance for adjusting the main light emission.
