  • Patent number: 8251811
    Abstract: A game machine includes playing content of a player in a game play part, in which the player operates an operation target, to be reflected in an action of the operation target in a video image. Reproduction data is recorded for reproducing a scene of the operation target moving in a game space according to the operation of the player. Base video image data is stored for reproducing a base video image representing a scene of a predetermined region of the game space. A video image is displayed based on a base video image and a reproduced video image such that a time of displaying a predetermined scene of the base video image and a time of displaying a scene of the operation target moving in the predetermined region in the reproduced video image based on the reproduction data are synchronized.

  • Patent number: 8155190
    Abstract: A coding apparatus includes: an intra-coding complexity detecting section that detects an intra-coding complexity indicating a complexity of an intra-coding process; an inter-coding complexity detecting section that detects an inter-coding complexity indicating a complexity of an inter-coding process; a characteristic curve calculating section that calculates a characteristic curve indicating a value of strength data indicating the strength of a deblocking filter with a data amount per unit time of coded data as a variable, on the basis of the intra-coding complexity and the inter-coding complexity; and a strength value calculating section that calculates a value of the strength data by substituting a data amount of the coded data into the characteristic curve.

  • Patent number: 8148505
    Abstract: An ?-selective glycosylation process of a glycosylation reaction between a sugar structure of hexose or an aldose having a chain with six or more carbon atoms in the molecule, which is a monosaccharide or a reducing end of an oligosaccharide with two or more monosaccharide residues connected by glycosidic linkages (an oligosaccharide with two monosaccharide residues is disaccharide) (also referred to as “a disaccharide to an oligosaccharide”) or a sugar chain and alcoholic hydroxyl group or thiol group, to obtain a sugar structure glycoside containing ?-glycoside at a high ratio, under the ring-shaped formation of a protective group in a silyl acetal structure over hydroxyl groups at positions 4 and 6 in the sugar structure. By the process, highly selective ?-glycosylation of sugar structure can be progressed in a simple and efficient manner.

  • Publication number: 20090280895
    Abstract: A game machine is provided which enables playing content of a player in a game play part, in which the player operates an operation target, to be reflected in an action of the operation target appearing in a video image displayed in a video image watching part. A replay data recording unit (90) records reproduction data for reproducing a scene of the operation target moving in a game space according to the operation of the player. A base video image data storage unit (92) stores base video image data for reproducing a base video image representing a scene of a predetermined region of the game space. A video image screen display controlling unit (94) causes a video image, which is based on a base video image and a reproduced video image, to be displayed such that a time of displaying a predetermined scene of the base video image and a time of displaying a scene of the operation target moving in the predetermined region in the reproduced video image which is based on the reproduction data are synchronized.
