  • Publication number: 20170073801
    Abstract: An aluminum alloy has high thermal conductivity without requiring an addition of metal elements such as iron and a method for producing the aluminum alloy. The aluminum alloy is obtained from a semi-solid material with a chemical composition containing 2 to 6 wt % of silicon (Si) and 0.7 wt % or less of magnesium (Mg), with the balance being aluminum (Al) and unavoidable impurities. It has a granular crystalline structure. The aluminum alloy is produced by a heating step of semi-solid material. A forming step is performed with semi-solid material obtained in the heating step S1. After the forming step, a heat treatment step is performed at 190° C. to 290° C. for 1 to 5 hours.

  • Patent number: 9560368
    Abstract: High-quality video is provided using a small amount of coded bits. The moving picture decoding method performs inter-frame prediction processing. With the aforementioned inter-frame prediction processing, blocks with similar motion vectors from among the motion vectors in multiple blocks that have already been decoded are combined and a combined area is computed. A predicted vector for a target block to be decoded is computed using the motion vector of the aforementioned combined area, and a motion vector for the aforementioned target block is computed based on the aforementioned predicted vector and a difference vector which is included in a coded stream that is input. A predicted image is generated using the aforementioned motion vector, and a difference image which is included in the aforementioned coded stream and the aforementioned predicted image are added to generate a decoded image.

  • Patent number: 9521417
    Abstract: An image encoding device that appropriately estimates a prediction vector by avoiding an uncoded macro block (MB) is disclosed. The device determines a start point of searching a motion vector for an encoding target region, from the prediction vector for the target region which is determined with motion vectors for surrounding blocks around the target region and in accordance with a predetermined rule, and starts searching for the motion vector from the search start point. If the size of the encoding target region cannot be acquired during calculation of the prediction vector, the device determines the size of the encoding target region, from the size of an encoded region other than the target region. If at least one of the motion vectors for the surrounding blocks cannot be acquired, the device calculates the prediction vector using alternatively a motion vector of an encoded block outside of the target region.

  • Patent number: 9438907
    Abstract: Suppression of prediction error accumulating in an intra prediction is described. A motion picture encoding apparatus that performs encoding processing for each pixel block using a motion picture encoding method includes intra prediction processing for generating a prediction image using correlation of pixels therearound, and in the intra prediction processing, the motion picture encoding apparatus has processing for generating a quasi-prediction image from an input image, wherein when a prediction mode is determined, a weight is given to a pixel serving as a reference pixel in the intra prediction processing, and thus, the prediction mode is determined. When the weight is set at one or more, an error of a pixel serving as a reference pixel in a subsequent block is emphasized, and therefore, a prediction mode that is likely to propagate the error to the subsequent block is less likely to be selected.

  • Patent number: 9277213
    Abstract: Provided is a video encoding device having an AFF-mode-determining unit (140) for determining the AFF mode when an input image is an interlaced image, and a video encoding unit (110) for encoding the input image depending on a result of the mode determination obtained from the AFF-mode-determining unit (140). The AFF-mode-determining unit (140) makes a determination combining: a mode determination result based on each of a texture value when an image is treated as a field and a frame, or based on an equivalent object; and a mode determination result based on the ease of predicting a motion vector in both encodings estimated with reference to a previously obtained movement vector, or based on the cost.

  • Publication number: 20150373365
    Abstract: Provided is a video encoding/decoding technique for improving the compression efficiency by reducing the motion vector code amount. In a video decoding process, the prediction vector calculation method is switched from one to another in accordance with a difference between predetermined motion vectors among a plurality of motion vectors of a peripheral block of a block to be decoded and already decoded. The calculated prediction vector is added to a difference vector decoded from an encoded stream so as to calculate a motion vector. By using the calculated motion vector, the inter-image prediction process is executed.
