An exposure control technique that makes it possible, even when photographing is performed in an enlarged display state of live view, to obtain an image photographed with correct exposure, by causing a setting shifting function to operate. When an enlargement instruction is received from a user when images acquired by an image pickup device are being sequentially displayed on an image display section, a camera control circuit causes an enlarged image corresponding to a partial area of an object area to be displayed on the image display section. If an exposure is to be changed when the enlarged image is being displayed, the camera control circuit changes the exposure, based on a result of photometry of the image acquired by the image pickup device before the enlarged image is displayed on the image display section.
