Abstract: The present invention provides an imaging apparatus that individually obtains high image quality, restored images for a plurality of different directions at a wide angle of view without using a lens, and an imaging module using such an imaging apparatus. In an imaging apparatus according to an aspect of the invention, incident light is divided into a plurality of azimuthal regions by a directional sensor, and images corresponding to the azimuthal regions are restored from a plurality of projection images acquired corresponding to the azimuthal regions. Accordingly, incident light from oblique directions does not become noise to incident light from a front direction, and projection images can be individually acquired for the azimuthal regions throughout a wide range from the front direction to the oblique directions.

Abstract: A method of manipulating at least a portion of a character model into a pose involving a library data having a plurality of deformations, where each deformation is associated with index values of one or more distance measurement nodes. One or more distance measurement nodes are defined for the portion of the character model, wherein each distance measurement node comprises a number of points on a surface defined by the geometry of the character model, wherein the points are separated by a distance value. A particular pose is selected for the character model portion to establish an initial model by selecting values for the pose controls. For the particular pose, a value of the distance measurement nodes is determined. At least one deformation is selected from the library data based in the value of the distance measurement nodes and applied to the initial model to generate a deformed model.

Abstract: A system for videoconferencing that offers, among other features, extremely low end-to-end delay as well as very high scalability. The system accommodates heterogeneous receivers and networks, as well as the best-effort nature of networks such as those based on the Internet Protocol. The system relies on scalable video coding to provide a coded representation of a source video signal at multiple temporal, quality, and spatial resolutions. These resolutions are represented by distinct bitstream components that are created at each end-user encoder. System architecture and processes called SVC Thinning allow the separation of data into data used for prediction in other pictures and data not used for prediction in other pictures. SVC Thinning processes, which can be performed at video conferencing endpoints or at MCUs, can selectively remove or replace with fewer bits the data not used for prediction in other pictures from transmitted bit streams.

Abstract: In a parameter setting method, when a wireless communication device has wired connection to a different device, the wired connection is used to acquire wireless setting values. If the wireless communication device has no wired connection to the different device, short distance wireless communication is used to acquire the wireless setting values from the different device. When the wireless setting values are acquired, notifying to the user is performed depending on an acquisition method.
