摘要： The invention provides a three-dimensional (3D) image processing circuit and a synchronization signal correction method thereof. The 3D image processing circuit is adapted to process a 3D image signal. The 3D image signal includes an image synchronization signal and a view switching signal. The 3D image processing circuit includes a synchronization signal correction circuit coupled to the image processing circuit. A synchronization circuit of the synchronization signal correction circuit receives an image synchronization signal processed by the image processing circuit and simultaneously receives the view switching signal. The synchronization circuit compares the processed image synchronization signal with the view switching signal, so as to output a view switching signal synchronized with the processed image synchronization signal. The invention further provides an image display device including the above 3D image processing circuit.

摘要： A viewing direction may define an angle/visual portion of a spherical video at which a viewing window is directed. A trajectory of viewing direction may include changes in viewing directions for playback of spherical video. Abrupt changes in the viewing directions may result in jerky or shaky views of the spherical video. Changes in the viewing directions may be stabilized to provide stabilized views of the spherical video. Amount of stabilization may be limited by a margin constraint.

摘要： A method for selecting spectator viewpoints in volumetric video presentations of live events includes receiving a plurality of video streams depicting an event occurring in a venue, wherein the plurality of video streams are provided to a processor by a plurality of cameras which are geographically distributed within the venue, identifying an initial position of a target that is present in the venue, based on an analysis of the plurality of video streams, compositing the plurality of video streams to produce a first volumetric video traversal of the live event that follows the target through the venue, predicting a future position of the target in the venue at a future point in time, based in part on a current position of the target, and sending an alert to a display device that is streaming a volumetric video presentation of the event, wherein the alert indicates the future position of the target.

摘要： Converting variable frame rate video to fixed frame rate video is described. A variable frame rate (VFR) video having source frames with varying frame durations is obtained. A fixed frame rate for the VFR video is determined. A mapping is generated which maps the source frames of the VFR video to a sequence of result frames of the fixed frame rate. To generate the mapping, a suitable source frame is chosen for each result frame using one or more mapping rules. After the mapping is generated, the mapping is adjusted to improve smoothness of motion of the VFR video by adding at least one skipped source frame to the mapping and removing at least one repeated source frame from the mapping. The VFR video is then converted into, or interpreted as, a fixed frame rate video having the determined fixed frame rate based on the adjusted mapping.

摘要： In a system, first and second detection devices are provided in mutually different places in a real space and each configured to image the real space and obtain three-dimensional information including data of a distance to a predetermined point on an object provided in the real space and direction information as to a direction of a predetermined part of the object. The system generates information related to relative positions and installation directions of the first and second detection devices on the basis of: the data of the distance to the predetermined point on the object and the direction information regarding the object, the data of the distance and the direction information being obtained by the first detection device; and the data of the distance to the predetermined point on the object and the direction information regarding the object, the data of the distance and the direction information being obtained by the second detection device.

摘要： The present invention discloses a method for performing original real-time video broadcasting with non-stationary panoramic video on virtual reality headset, comprising PC terminal one and PC terminal two, also a panoramic camera connected to the PC terminal one, a four-axis electromechanical structure connected to the panoramic camera, and a virtual reality headset connected to the PC terminal two. The present invention enables the panoramic camera to perform live video transmission on the virtual reality headset in low delay or real time, which will realize virtual reality of different scenarios, for example, the panoramic HD camera can be placed in the car cockpit, restoring the driving environment for the user perfectly. With real-time panoramic video transmission, user may complete the remote control of the car with the same experience. When the user swings the head back and forth or tilts the body, the four-axis electromechanical structure allows the originally fixed panoramic camera to make spatial changes to its position.
