  • Patent number: 8830393
    Abstract: Spatial or temporal interpolation may be performed upon source video content to create interpolated video content. A video signal including the interpolated video content and non-interpolated video content (e.g. the source video content) may be generated. At least one indicator for distinguishing the non-interpolated video content from the interpolated video content may also be generated. The video signal and indicator(s) may be passed from a video source device to a video sink device. The received indicator(s) may be used to distinguish the non-interpolated video content from the interpolated video content in the received video signal. The non-interpolated video content may be used to “redo” the interpolation or may be recorded to a storage medium.

  • Patent number: 7990475
    Abstract: A system determines a plurality of frames. The plurality of frames is a subset of a set of frames comprising at least a portion of a video clip. The frames are candidates to represent the set of frames. The system calculates a motion vector for each of the frames within the plurality of frames. The motion vector indicates an amount of motion in each of the frames with respect to at least one other frame from the plurality of frames. The system assesses a strength value for each of the frames. The strength value indicates an assessment of pictorial quality of each of the frames. The system selects a representative frame from the plurality of frames based on the motion vector and strength value. The representative frame indicates a most favorable representation of the plurality of frames.

  • Patent number: 7218791
    Abstract: The present invention relates to an image processing apparatus for generating an image having a high density in the direction of time and having a natural-looking motion blur. The correlation calculators 103 and 104 respectively calculate a correlation between pixel data of a target pixel in a target frame #n from among frames and pixel data of a corresponding pixel in a first frame #n?1 next to the target frame #n and a correlation between the pixel data of the target pixel in the target frame #n and pixel data of a corresponding pixel in a second frame #n+1 next to the target frame #n. The half-side pixel value generator 105 generates first pixel data in a first synthesis frame generated between the target frame #n and one of the first frame #n?1 and the second frame #n+1 containing the corresponding pixel having the pixel data with a larger correlation.
