Patent number: 6650253Abstract: In a map display device, a surface storing unit stores surface information which defines a curved surface having a form that depends on positions of portions of a map which are to be enlarged and/or contracted. A mapping unit maps the map onto the curved surface defined by the surface information. A projecting/displaying unit projects the mapped map onto a flat virtual screen, and displays the projected image. Here, by defining the curved surface so that each part of the curved surface forms an intended angle with a line of sight in the projection, the image is displayed with desired portions enlarged and/or contracted, while maintaining connections of roads. The same effect can also be achieved by projecting the map onto a virtual screen having the form of the curved surface.Type: GrantFiled: May 29, 2001Date of Patent: November 18, 2003Assignee: Matsushita Electric Industrial Co., Ltd.Inventors: Yoshiyuki Mochizuki, Keiichi Senda, Kenji Nishimura

Patent number: 6573842Abstract: When a user indicates a portion of a map to be enlarged or contracted, a surface generating unit generates surfaces by gradually changing a surface from a first shape to a second shape, the first shape corresponding to a position of a map portion previously indicated and the second shape corresponding to a position of the map portion currently indicated. A mapping unit maps the map onto the generated surfaces in sequence, to obtain mapped images. A projecting/displaying unit sequentially projects the mapped images onto a flat virtual screen, and displays the projected images. Thus, the desired portion of the map can be enlarged/contracted, while maintaining connections of roads. Also, the map display can be transformed smoothly, even when the target of enlargement/contraction changes from one map portion to another according to the user's indications. This helps the user comprehend the contents of the map quickly and accurately.Type: GrantFiled: September 25, 2001Date of Patent: June 3, 2003Assignee: Matsushita Electric Industrial Co., Ltd.Inventors: Yoshiyuki Mochizuki, Keiichi Senda
