  • Patent number: 10430664
    Abstract: A system provides automated editing of a media file. Frames of a media file are extracted and feature vectors are generated based thereon. The feature vectors are clustered according to similarity of the content of the feature vectors and the temporal proximity of frames corresponding to the feature vectors in the media file. Clusters are ranked and selected according to the ranking. Segments of the media file corresponding to the selected clusters are combined into a highlight video. Hotspots in a media file may be identified in a media file by detecting local maxima in a measure of movement of pixels between frames. Clusters may be ranked and selected according to an iterative algorithm that identifies clusters that are the most different from an average of the feature vectors and from other selected clusters.

  • Patent number: 10068309
    Abstract: An interface apparatus and method of operating the same are provided. The interface apparatus receives an uncompressed image data read request using a first addressing scheme at a first bus interface and transmits a compressed image data read request using a second addressing scheme from a second bus interface. Address translation circuitry translates between the first addressing scheme and the second addressing scheme. Decoding circuitry decodes a set of compressed image data received via the second bus interface to generate the set of uncompressed image data which is then transmitted via the first bus interface. The use of a second addressing scheme and image data compression is thus transparent to the source of the uncompressed image data read request, and the interface apparatus can therefore be used to connect devices which use different addressing schemes and image data formats, without either needing to be modified.

  • Patent number: 9996906
    Abstract: An artifact detector detects artifacts in a video sequence comprising interpolated frames generated by performing motion estimation. The detector comprises a pixel processor which processes pixel values in first and second input frames of the video sequence to identify respective blocks of pixels representing an image feature. A feature-matching module matches identified blocks in the first input frame with corresponding identified in the second input frame to determine matched block pairs. For each matched block pair, a feature-detector module: (i) identifies a block of an interpolated frame between the first and second input frames corresponding to the matched block pair, and (ii) characterizes the corresponding block of the interpolated frame as an artifact in dependence on a determination of whether said corresponding block does or does not represent the image feature. A corrector module corrects the interpolated frame based on the characterization of the blocks of the interpolated frame.

An IP-conversion selection signal indicating a determination result whether or not the reliability of the video stream meets a predetermined level is input into a back-end from a CPU. A selector refers to the IP-conversion selection signal, and when the CPU determines that the reliability of the video stream is lower than the predetermined level, image data having undergone interpolation by the inter-field scanning line interpolating unit is selected as an image to be displayed.

  • Patent number: 8643698
    Abstract: A single progressive 1080P60 side-by-side 3D video or a single progressive 1080P60 2D video is captured for transmission to interlaced receivers such as a legacy 1080i capable video receiver. A video transmitter splits the captured 1080P60 video into a plurality of even-indexed line pictures and odd-indexed line pictures. Lines of the plurality of even-indexed line pictures and odd-indexed line pictures are reassembled to generate two interlaced video sequences such as two 1080i video sequences. The video transmitter compresses the generated two 1080i video sequences, respectively, utilizing different compression algorithms, for example. Pictures that originate from the same one of the plurality of pictures in the captured 1080P60 video may be synchronized for a progressive display at the legacy 1080i capable video receiver. The legacy 1080i capable video receiver may decode the synchronized pictures from the video transmitter so as to restore the captured 1080P60 video for display in progressive format.

  • Patent number: 8559798
    Abstract: A rendering process for rendering an image frame and a postprocess for adapting the image frame to a display are separated. A rendering processing unit 42 generates an image frame sequence by performing rendering at a predetermined frame rate regardless of a condition that the image frame should meet for output to the display. A postprocessing unit 50 subjects the image frame sequence generated by the rendering processing unit to a merge process so as to generate and output an updated image frame sequence that meets the condition. Since the rendering process and the postprocess are separated, the image frame sequence can be generated regardless of the specification of the display such as resolution and frame rate of the display.
