If subject types of a still image material and a panoramic image are different, for example if the subject type of the still image material is animal and the subject type of the panoramic image is landscape, a layout determination unit determines a representative position in the point image as a position for placing the still image material. If a point image is of the same subject type, the layout determination unit determines, as the position for placing the still image material, a position outside the area of the panoramic image near the representative position in the point image. Thus, if there are a plurality of still image materials shot with different zoom factors and corresponding to the same point image, the layout determination unit can determine the layout of the still image materials according to the zoom factor for each still image material.
