Image capturing apparatus, control method therefor, program, and recording medium

Abstract

An image capturing apparatus capable of high dynamic range shooting for compositing a plurality of images captured with different exposures in temporarily continuous frames includes: an image capturing unit configured to repeatedly capture a relatively-low-exposure image and a relatively-high-exposure image in temporarily continuous frames; an image generation unit configured to generate a first image obtained by correcting the low-exposure image on a basis of reference exposure and a second image obtained by correcting the high-exposure image on a basis of the reference exposure; a calculation unit configured to calculate reference exposure, which is used for performing image capturing of a subsequent frame, on a basis of the first image and the second image; and a correction unit configured to correct exposure conditions, under which a relatively-low-exposure image and a relatively-high-exposure image in a subsequent frame are captured, on a basis of the reference exposure calculated by the calculation unit.
