An image is placed, based on a predetermined designation input, on a predetermined placement position in relation to a display area, and displayed. The image is enlarged and reduced in accordance with an enlargement ratio of the image, and an area within which the placement position can be set is changed in relation to the display area in accordance with the enlargement ratio. Then, based on an obtained designation input, a position within the area, which position corresponds to the designation input, is calculated as a placement position, and the image having been enlarged and reduced is placed on the placement position. The image is then displayed on a display device.
