An image capturing apparatus chooses a main face from among faces detected in successively captured images based on a degree of priority calculated for each detected face. Moreover, the image capturing apparatus compares the degree of priority assigned to the face corresponding to a last chosen main face and the degrees of priority assigned to the faces corresponding to faces other than the main face, and then counts the number of times the degrees of priority assigned to the faces corresponding to faces other than the main face exceed the degree of priority assigned to the face corresponding to the main face. When one of the number of times counted for the faces other than the main face exceeds a preset threshold value, the image capturing apparatus performs a main face changeover to the one of the faces.
