  • Patent number: 8553072
    Abstract: Inter-frame blanking involves blanking the transition period between two video frames of a three-dimensional video signal. One implementation includes receiving a three-dimensional video signal and determining a frame overlap interval. The frame overlap interval is the time period in which a display device will concurrently display at least one portion of a first video frame and at least one portion of a second video frame during a transition period. The implementation also includes, based on the frame overlap interval, generating an inter-frame blanking signal that instructs a blanking device to filter the display of the three-dimensional video signal.

    Abstract: Controlling a shuttering device. A method includes detecting from a use environment a set of encoded signals for use in controlling a shuttering device. The set of encoded signals are analyzed to determine an encoding scheme for the set of encoded signals. The encoded signals are prospectively decoded in the environment according to the determined encoding scheme to control the shuttering device.

  • Publication number: 20120140051
    Abstract: A shuttering device can improve a viewer's perception of displayed three-dimensional (3D) content by concurrently shuttering both of the viewer's eyes during frame transitions. One implementation includes the shuttering device receiving a shuttering signal synchronized to a display of 3D content at a display device. In response to the shuttering signal, the shuttering device can shutter the display of the 3D content. The shuttering can include shuttering a first shuttering component during a first time period corresponding to display of second eye 3D content. The shuttering can also include shuttering both the first shuttering component and a second shuttering component concurrently during a second time period corresponding to display of a transition from the second eye 3D content to first eye 3D content. Additionally, the shuttering can include shuttering the second shuttering component during a third time period corresponding to display of the first eye 3D content.

  • Publication number: 20120140032
    Abstract: Converting three-dimensional (3D) video content for use by a variety of different display devices of different capabilities involves decoding a 3D video signal into two frame buffers. One implementation includes receiving an input 3D video signal that comprises video frames having image data for viewing by a first eye and image data for viewing by a second eye. The implementation includes generating, from the input 3D signal, a first and second frame buffer. The first frame buffer can store a complete first image for viewing by the first eye, while the second frame buffer can store a complete second image for viewing by the second eye. The implementation can further comprise encoding the complete first image into a first video frame and encoding the complete second image into a second video frame of an output 3D video signal.

  • Publication number: 20120140033
    Abstract: Displaying three-dimensional (3D) video content to low frame-rate display devices can involve sending 3D video content to a display device. One implementation includes sending a first image for viewing by a user's first eye to the display device via first video frame(s) and sending a second image for viewing by the user's second eye via second video frame(s). Additionally, the implementation includes transmitting an inter-frame blanking signal to a blanking device. The inter-frame blanking signal instructs the blanking device to blank concurrently both of the user's eyes during a transition period of the display device. During the transition period, the display device concurrently displays both a portion of the first video frame(s) and a portion of the second video frame(s).

  • Publication number: 20120140034
    Abstract: A video conversion device that converts 3D content for viewing on low frame-rate display devices can include a video signal input device for receiving a 3D content, and a video signal output device for sending an output video signal to a display device. The video conversion device can also include processing units that convert 3D content to an output signal adapted for the display device. The processing units can also generate a shuttering signal, which instructs a shuttering device to occlude a user's view of the output signal, and a transmitter for transmitting the shuttering signal. Additionally, an accessory device that enables a computing system to convert and send 3D content can include a computing system interface device, and a shuttering signal transmitter. The accessory device can also include instructions for converting a 3D video signal for a display device, and for generating a shuttering signal.
