Abstract
A distance measurement apparatus includes one or more processors, and a memory storing instructions which, when executed by the one or more processors, cause the distance measurement apparatus to function as a calculation unit configured to calculate distance information corresponding to an image captured by an imaging apparatus using an image sensor that captures an object image focused on the image sensor via an optical system, a temperature information obtaining unit configured to obtain temperature information of the imaging apparatus at different times, and a distance correction unit configured to correct the distance information, wherein the distance correction unit corrects the distance information based on the temperature information at a time at which a first image capturing is performed and the temperature information at a time before the first image capturing is performed.
