It is arranged so that stereoscopic images will not overlap one another. A stereoscopic image to be pasted in a free-layout electronic album is selected. The amount of parallax of the stereoscopic image to be pasted in this electronic album is set. When this is done, the selected stereoscopic image is enlarged or reduced in size so as to take on the set amount of parallax. Automatic layout for pasting enlarged or reduced stereoscopic images on each page of the electronic album in such a manner that these stereoscopic images will not overlap one another is carried out. The result of the layout is displayed.
