  • Patent number: 11941744
    Abstract: Various methods are provided for generating motion vectors in the context of 3D computer-generated images. An example method includes generating, for each pixel of one or more objects to be rendered in a current frame, a 1-phase motion vector (MV1) and a 0-phase motion vector (MV0), each MV1 and MV0 having an associated depth value, to thereby form an MV1 texture and an MV0 texture; converting the MV1 texture to a set of MV1 blocks and converting the MV0 texture to a set of MV0 blocks; and outputting the set of MV1 blocks and the set of MV0 blocks for image processing.

  • Publication number: 20230245326
    Abstract: Various methods are provided for generating motion vectors in the context of 3D computer-generated images. An example method includes generating, based on a current frame to be rendered, a block-level motion vector with depth (MVD) texture comprising a set of block-level motion vectors each having an associated depth value, outputting the block-level MVD texture for image processing on a first channel, and outputting at least a portion of the current frame on a second channel.

  • Patent number: 9491398
    Abstract: A method and system for detecting and processing a series of video frames includes receiving the series of video frames, determining whether the video frames are associated with a recognized non-video source, and depending on the determination, processing the video frames using a variety of techniques. A system may detect whether each video frame is a repeat frame or a new original frame, keep the new original frames, discard the repeat frames, and then adjust one or more timestamps associated with the new original frames so as to conform to an intermediate frame rate. The frame indexes and timestamps associated with the new original frames are stored in a FIFO or buffer. The system can interpolate video frames using the stored timestamps, and output a series of video frames. The output video stream is delivered at any frame rate and can include original video frames and interpolated video frames.

  • Patent number: 7880818
    Abstract: We describe a device and an associated method that includes an EHT signal processing module to generate a compensated gain signal responsive to a first EHT signal. A field fly-back processing module generates a first correcting signal responsive to a first VFB signal. A horizontal scanning correction module generates a predistortion signal responsive to the compensated gain signal. A first digital to analog conversion module converts the predistortion signal into a corresponding analog predistortion signal. A field scanning correction module generates a correcting wave responsive to the compensated gain signal and the first correcting signal. A pulse width modulated module generates a modulated correcting wave by pulse width modulating the correcting wave. A power amplification module generates an amplified modulated correcting wave by amplifying the modulated correcting wave. And a cathode ray tube displays an image responsive to the analog predistortion signal and the amplified modulated correcting wave.
