摘要： Embodiments provide a method and a client for playing back a panoramic video. Under the method, a client device can obtain user field of view information and recommended field of view information of a panoramic video. The client can then determine, based on the user field of view information and the recommended field of view information, that a field of view range corresponding to a recommended field of view is not within a range of a user field of view. The client can display an image corresponding to the user field of view and an image corresponding to the recommended field of view. An image corresponding to a recommended field of view can be prompted and presented, so that the user independently determines whether to switch a field of view.

摘要： A display control method with which a captioned image can be displayed in the visual field of a user irrespective of a change in the line-of-sight direction of the user. The display control method includes a step of generating visual-field image data, which represents a visual-field image, based on the line-of-sight direction of a user and 360-degree space image data. The method further includes a step of receiving captioned image data, which represents a captioned image. The method further includes a step of displaying on an HMD a composite image of the visual-field image and from the captioned image, based on the visual-field image data and the captioned image data. The composite image is displayed is displayed at a given place in the visual-field image irrespective of a change in the line-of-sight direction of the user.

摘要： Systems and methods are presented for processing three-dimensional (3D or 3-D) or pseudo-3D media content. The programming includes closed caption (CC) information that includes caption data and a location identifier that specifies a location for the caption data within the 3D programming. The programming information is processed to render the caption data at the specified location within the media content and to present the programming on the display. By encoding location identification information into the three-dimensional media content, a high level of configurability can be provided and the 3D experience can be preserved while captions are displayed.

摘要： A system of transferring of three dimensional (3D) image data is described. A 3D source device (10) provides 3D display signal (56) for a display (13) via a high speed digital interface like HDMI. The 3D display signal has frames constituting the 3D image data according to a 3D video transfer format, in which format the frames comprise at least two different frame types. Each frame has a data structure for representing a sequence of digital image pixel data, and represents a partial 3D data structure. The 3D source device includes frame type synchronization indicators in the 3D display signal. The display detects the frame type synchronization indicators and frame types, and generates the display control signals based on synchronizing the partial 3D data structures in dependence of the frame type synchronization indicators.

摘要： An apparatus and method provide logic for processing information. In one implementation, an apparatus may include a determination unit configured to determine a first spatial position of a portion of an operating tool disposed within a threshold distance of a surface of the determination unit. The first spatial position may be determined relative to the determination unit surface in a depth direction. The apparatus may also include a control unit configured to generate a first signal to display a stereoscopic image to a user at a first display position. The first display position may be disposed within a predetermined distance of the first spatial position.

摘要： It is an object of the present invention to reduce a possibility that a subject (specific object) of a virtual viewpoint image and a virtual object area overlap. To achieve the object, the present invention comprises a first identifying unit for identifying a three-dimensional position of the specific object captured respectively from different directions by a plurality of cameras; a second identifying unit for identifying a three-dimensional position of a virtual viewpoint related to generation of the virtual viewpoint image based on captured images obtained by the plurality of cameras; and a determining unit for determining a position of the virtual object area to which a virtual object to be displayed in the virtual viewpoint image is disposed, based on the three-dimensional position of the specific object identified by the first identifying unit and the three-dimensional position of the virtual viewpoint identified by the second identifying unit.
