摘要:
An image prediction encoding device 100 includes a prediction signal generator 103 that produces a prediction signal with respect to a target pixel signal of a target region that is among a plurality of regions divided by a block division unit 102, a motion estimator 113 that searches for a motion vector required for the production of the prediction signal from an already reproduced signal, and a subtractor 105 that produces a residual signal indicating a difference between the prediction signal and the target pixel signal. The prediction signal generator 103 determines a search region that is a partial region of the already reproduced signal based on the motion vector and produces one or more type 2 candidate prediction signals. The prediction signal generator 103 includes a candidate prediction signal combining unit 203 that produces the prediction signal by processing the plurality of type 2 candidate prediction signals and a type 1 candidate prediction signal produced based on the motion vector in accordance with a predetermined combining method.

In order to improve the encoding efficiency while avoiding an increase in the size or memory band of a frame memory and having adaptability in the encoding/decoding processing of a moving picture, a bit length extension converter converts a target picture having a bit length N into an extended target picture having a bit length M, a compressor encodes the converted picture, and an expander restores the encoded picture. Then, a bit length reduction converter converts the picture into a reproduction picture having a bit length L smaller than the bit length M, and this reproduction picture is stored in a frame memory as a reference picture.

A moving image encoding and decoding system may include a moving image encoding device and a moving image decoding device that provides motion vector prediction and encoding of a difference motion vector even when a block serving as a candidate of motion vector prediction does not have significant motion information. The moving image encoding device 100 includes a motion vector predictor 114 that may select a first region from already encoded regions stored in a frame memory 104. When, for example, the selected region does not have a reference frame number, the moving image encoding device can search for and select a second region having a determined level of correlation with a template region. The template region is composed of pixel signals already reproduced from a reference image specified with a reference frame number associated with a target region. The moving image encoding device 100 may produce a prediction motion vector based on the spatial positional relationship between the target region and the selected first or second region. Using the prediction motion vector, a difference motion vector can be calculated.

A plasma etching method for plasma-etching an anti-reflective coating formed on a target object includes the step of placing the target object into a processing chamber having a first electrode and a second electrode provided while facing each other, the target object including an etching target film, the anti-reflective coating and a patterned photoresist film sequentially formed in that order on a substrate.

A process for producing an aliphatic polyester through ring-opening polymerization of a cyclic ester, wherein a partial polymer in a molten state is continuously introduced into a twin-screw stirring device to continuously obtain a partial polymer in a solid pulverized state, the partial polymer is subjected to solid-phase polymerization, and the resultant polymer is melt-kneaded together with a thermal stabilizer to be formed into pellets. As a result, an aliphatic polyester of a high molecular weight and with little discoloration is produced efficiently.

A process for producing an aliphatic polyester by subjecting a cyclic ester to ring-opening polymerization, which comprises adding water to a cyclic ester purified to the extent that a water content is at most 60 ppm to control an overall proton concentration in the cyclic ester, thereby controlling at least one physical property among melt viscosity, molecular weight and yellowness index of the resulting aliphatic polyester.

A variable transmission ratio apparatus for effectively preventing ratcheting between a flexible spline and a circular spline caused by a steering operation performing in a locked state. A variable transmission ratio apparatus includes a strain wave gear mechanism for adding rotation resulting from motor drive to rotation from an input shaft resulting from a steering operation and transmitting the added rotation to an output shaft, a housing accommodating the strain wave gear mechanism and the motor and fixed to a non-rotating portion, and a lock device for locking the housing and a motor shaft in a manner prohibiting relative rotation therebetween. Among the circular splines forming the strain wave gear mechanism, the number of teeth of the circular spline connected to the output shaft is greater than the number of teeth of the circular spline connected to the input shaft.

A program for pasting a predetermined image onto a character of a game in a game machine. The program enables a user to create an image consisting of two-dimensional coordinates and to arrange the image created. The program includes the ability to project the image onto a character, at arbitrary positions, in the vicinity of the character in a three-dimensional virtual space, and for pasting on the character a projected image created by projecting the image onto the character from the projection light source.
