Abstract

An apparatus includes an acquisition unit configured to acquire an image, a first detection unit configured to detect a first region corresponding to a first feature from the image, a second detection unit configured to detect a second region corresponding to a second feature from the image, a measurement unit configured to perform photometric measurement on the first region and the second region, a determination unit configured to determine an exposure based on a weighted average of a first photometric value of the first region that is acquired by the measurement unit and a second photometric value of the second region that is acquired by the measurement unit before the first photometric value is acquired, and an output unit configured to output information about the exposure.
