Patent number: 8489993Abstract: A game apparatus saves, in accordance with an instruction of a user, a photographing image taken by an inward camera or an outward camera, or a handwriting image of a handwritten note inputted using a touch panel. Moreover, in accordance with an instruction of the user, position information is saved together with the photographing image or the handwriting image. That is, a photographing place or a creation place of the handwritten note is registered on a map. When the photographing image or the handwriting image is reproduced, an image of a landmark set near a position on the map indicated by the position information is reproduced before the photographing image or the handwritten image.Type: GrantFiled: September 10, 2009Date of Patent: July 16, 2013Assignee: Nintendo Co., Ltd.Inventors: Hiroaki Tamura, Nobuhito Koganezawa, Fumihiko Tamiya, Koichi Nakao, Ryota Oiwa, Yosuke Fujino
