  • Patent number: 8907968
    Abstract: An image rendering device realizes stereoscopic viewing of a joint background image. A DIBR unit 17 applies pixel shifting to each background image constructing the joint background image and also conducts boundary processing relative to the pixel shifting. The joint background image is composed of one or more background images stitched together along their edges on a three-dimensional model. The pixel shifting is to shift pixels of each background image in the row direction. The amount of shift applied to each pixel is determined based on the depth value of a corresponding pixel of a depth image. The boundary processing is to extract pixels shifted out of the display region of a given background image as a result of pixel shifting and add the extracted pixels to an edge of another background image adjacent to the given background image in the row direction.

  • Patent number: 8749753
    Abstract: The upper end of a static gas bearing member of a wafer side seal unit is connected to an edge section on the outgoing side of an exposure beam of a chamber in an air tight state via bellows, and the lower end surface is in a state forming a predetermined clearance with a wafer and a wafer holder. By this arrangement, the inside of the chamber is isolated from the outside. Accordingly, it becomes possible to maintain a vacuum environment in the periphery of the optical path of the exposure beam without arranging a vacuum chamber to house a wafer, a wafer holder, and a wafer stage, which allows the size of the entire exposure apparatus to be reduced, and also makes it easy to have access to the vicinity of the wafer stage.

  • Publication number: 20140143313
    Abstract: If an execution target application is an application with a high load for a client terminal (10), a mode switching unit (312) switches an execution system from a simplex processing mode to a distributed processing mode. On the other hand, upon receiving a switching notification for switching the execution system to the simplex processing mode from a server (102), the mode switching unit (312) causes a distributed display processing unit (311) to stop display processing for the application and sets the execution system of the application to the simplex processing mode.

  • Publication number: 20140115025
    Abstract: A device information acquisition unit acquires device information from a peripheral device via an ad hoc network. An integrated service determination unit determines an integrated service to be executed from among the integrated services defined by integrated service information based on an instruction from a user. A distribution script determination unit cross checks device information related to a client device and a specification requirement of the integrated service to be executed, and determines a client UI of the client device. A script distribution unit distributes, to each client device, the client UI that has been determined by the distribution script determination unit.
