  • Patent number: 10142627
    Abstract: A device includes one or more processors configured to derive, from among a plurality of intra prediction modes, M most probable modes (MPMs) for intra prediction of a block of video data. A syntax element indicating whether a MPM index or a non-MPM index is used to indicate a selected intra prediction mode of the plurality of intra prediction modes for intra prediction of the block of video data is decoded. Based on the indicated one of the MPM index or the non-MPM index being the MPM index, the one or more processors select, for each of one or more context-modeled bins of the MPM index, based on intra prediction modes used to decode one or more neighboring blocks, a context index for the context-modeled bin. The one or more processors reconstruct the block of video data based on the selected intra prediction mode.

  • Patent number: 10110896
    Abstract: An adaptive Motion JPEG encoding method is disclosed, including: acquiring a video sequence; encoding a current video frame of the video sequence into JPEG format based on a Huffman description table, generating encoded symbols corresponding to the current video frame and counting frequencies of occurrence of the encoded symbols corresponding to the current video frame; and updating the Huffman description table with Canonical Huffman encoding based on the frequencies of occurrence of the encoded symbols corresponding to the current video frame, the updated Huffman description table being used for encoding a next video frame adjacent to the current video frame of the video sequence into JPEG format. The adaptive Motion JPEG encoding method uses the correlation between the Huffman description tables of the adjacent frames to reduce the redundant information between the video frames. An adaptive Motion JPEG encoding system is also disclosed.

  • Patent number: 9516316
    Abstract: This disclosure describes techniques for coding transform coefficients for a block of video data. According to these techniques, a video coder (a video encoder or video decoder) determines whether a block of video data is a luma block or a chroma block. If the block of video data is a luma block, the video coder adaptively updates a VLC table index value based on a code number cn and value of a scaling factor. However, if the block of video data is a chroma block, the video coder adaptively updates the VLC table index value based on the code number cn and without using the scaling factor. The video coder uses the updated VLC table index value to select a VLC table of a plurality of VLC tables that are used to encode or decode the block of video data.

    Abstract: A calibration apparatus is provided. The calibration apparatus receives inputs of two reference images and plural items of parallax data; searches for plural feature points common to these two reference images; calculates parallaxes and parallax changing amounts, based on the parallax data related to the respective feature points in these two reference images, for each of the searched feature points; and calculates a correction value for the parameter based on the calculated parallaxes and parallax changing amounts. The two reference images are captured by one of the imaging devices at two locations, and the parallax data is calculated using these two reference images and two corresponding images based on positions of plural feature points common to the reference image and the corresponding image for each pair on a location basis. The two corresponding images are captured by another of the imaging devices at these two locations.

  • Patent number: 8982963
    Abstract: A first image stream has a first dynamic range and a first color space. First and the second image streams are received in a layered codec. The second image stream has a second dynamic range, which is higher than the first dynamic range. The first image stream is in the codec's base layer; the second image stream is in its enhancement layer. The first image stream is encoded to obtain an encoded image stream, which is decoded to obtain a decoded image stream. The decoded image stream is converted from the first non-linear or linear color space to a second, different color space to obtain a color converted image stream. A higher dynamic range image representation of the color converted image stream is generated to obtain a transformed image stream. Inverse tone mapping parameters are generated based on the transformed image stream and the second image stream.

  • Patent number: 8937644
    Abstract: Stereoscopic image capture is provided. A blur value expected for multiple pixels in left and right images is predicted. The blur value is predicted based on designated capture settings. A disparity value expected for multiple pixels in the left and right images is predicted. The disparity value is predicted based on the designated capture settings. Stressed pixels are identified by comparing the predicted disparity value to a lower bound of disparity value determined from the predicted blur value using a predetermined model. A pixel with predicted disparity value less than the lower bound is identified as a stressed pixel. The predicted disparity is adjusted by modifying the designated capture settings to reduce the number of stressed pixels, or an alert to the presence of stressed pixels is given to the user.

    Abstract: Techniques and circuitry provide fast, accurate, proper, and reliable transfer of configuration data from an on-chip nonvolatile memory to the programmable logic core of a programmable logic integrated circuit. A first technique includes not allowing the programmable logic to be configured until the data held in the on-chip nonvolatile memory can be read correctly and reliably. A second technique includes verifying the configuration data is transferred from the nonvolatile memory to the programmable logic core correctly and without error during the transfer process. These two techniques may be combined or used individually during the configuration of an integrated circuit.
