Abstract
An image capturing apparatus and a control method capable of obtaining an image with a wide dynamic range, without using a special image sensor. An amount of dynamic range enhancement for lessening an amount of blown-out highlights of an image is determined based on the amount of blown-out highlights. An image with enhanced dynamic range is then obtained, by performing image capture at a sensitivity that has been lessened based on the amount of dynamic range enhancement, and correcting a drop in brightness of the captured image due to the lessened sensitivity.
