  • Operating device, image display system, map display controller and program for map display controller
    Patent number: 8044934
    Abstract: An image display system has an operating device, a specifying device and an image display device. If the operating device receives a single operation from an exterior (i.e., from user), the operating device outputs first and second signals based on the single operation. The specifying device specifies a viewpoint and a sight line direction to look down a picture based on the first and second signals outputted by the operating device. The image display device displays an image of the picture in such a manner that the picture is looked down from the viewpoint in the sight line direction specified by the specifying device. As a result, the operation for adjusting the viewpoint and the sight line direction is facilitated.

  • Manufacturing method for hologram which can prevent the formation of ghant holograms due to noise light
    Patent number: 5648857
    Abstract: A manufacturing method for a hologram which can control the formation of a ghost hologram due to a surface reflected light caused on an interface with the atmosphere is disclosed. In the first manufacturing method for a hologram by a two-beam method or a one-beam method, on an interface between a substrate having a hologram photosensitive layer and the atmosphere is disposed a quarter-wave plate, and an incident light is converted from a circularly polarized light to a P-polarized light (or an S-polarized light) through the quarter-wave plate. On the other hand, in the second manufacturing method for a hologram, a substrate, which has a hologram photosensitive layer, is fittingly held by prisms on both sides thereof. A reference light is a P-polarized light, and an angle of the reference light to a surface reflected light on an interface of the reference light is set to be approximate to a right angle.
