  • Publication number: 20160330468
    Abstract: When a randomly-accessible inter picture is encoded, a prediction image generator sets a reference picture from among a plurality of randomly-accessible intra pictures, and performs a motion-compensated prediction using the set reference picture for a prediction process, and a variable length encoding unit 13 encodes both picture position information showing the position of the reference picture, and identification information showing that the randomly-accessible inter picture is randomly accessible, and multiplexes encoded data about both the picture position information and the identification information into a bitstream.

  • Publication number: 20160234523
    Abstract: A variable length encoder 23 multiplexes hint information into an entire region bitstream, the hint information including motion vector limitation information indicating a maximum range in which a search for a motion vector can be performed, GOP size limitation information indicating a GOP size which is the number of pictures belonging to a GOP, and reference configuration specification information indicating a picture to be referred to at the time of decoding each picture belonging to the GOP. As a result, a bitstream of the entire region which is suitable for efficient generation, with a low operation amount, of a bitstream of a partial region can be generated without causing a reduction in the compression efficiency of the bitstream of the entire region.

  • Publication number: 20160094860
    Abstract: An image encoding device includes an encoder that encodes a first field of a specific frame as an intra picture which is predicted by using only an ultra prediction, and that encodes the first field of the above-described specific frame, a second field of the above-described specific frame, a picture whose encoding order is later than that of the first field of the above-described specific frame later and whose display order is earlier than that of the first field, and another picture whose encoding order and also display order are later than those of the first field of the above-described specific frame in order of those pictures, and a multiplexer that multiplexes information showing that the first field of the above-described specific frame is a picture, in a bitstream, at which decoding can be started into the above-described bitstream.

  • Publication number: 20150023420
    Abstract: A loop filter unit 11 carries out a class classification of a local decoded image generated by an adding unit 9 into one class for each coding block having a largest size determined by an encoding controlling unit 2 and also designs a filter that compensates for a distortion piggybacked for each local decoded image belonging to each class, and also carries out a filtering process on the above-mentioned local decoded image by using the filter. A variable length encoding unit 13 encodes, as filter parameters, the filter designed by the loop filter unit 11 and used for the local decoded image belonging to each class, and a class number of each largest coding block.

  • Patent number: 8367082
    Abstract: The present invention provides a microgel having a mean particle size of 0.1-1,000 ?m, the microgel being produced from a gel which is formed by use of a hydrophilic compound capable of forming a gel. An external composition containing the microgel provides an excellent sensation during use; i.e., the composition provides neither sticky sensation during use nor frictional sensation. Furthermore, even when a large amount of a pharmaceutical ingredient, such as a whitening ingredient, or a salt is incorporated into the composition, the viscosity of the composition is not lowered, and the composition exhibits excellent viscosity increasing property. In addition, the composition exhibits long-term stability, without inviting separation of water.
