Abstract
A focus detection unit detects a focus state in one or more areas based on image data, a subject detection unit detects a subject from an image of the image data and outputs subject information, a determination unit determines whether or not one or more predetermined conditions are satisfied based on at least one of shooting setting information and the subject information, and determines whether or not to perform adjustment processing for correcting an effect of field curvature on the focus state. An adjustment unit adjusts the focus state if the adjustment processing is to be performed, and a calculation unit calculates a movement amount of a focus lens based on the focus state adjusted by the adjustment unit, or on the focus state detected by the focus detection unit in a case where the focus state is not adjusted.
