  • Patent number: 8379724
    Abstract: An image coding apparatus and an image coding method are provided for reducing arithmetic processing while keeping a high compression ratio. A coding process necessary for the bi-prediction motion search can be effectively reduced by determining a block size for a bi-prediction motion search or a center position for a motion search on the basis of a result of a motion search of a unidirectional prediction. Further, a compression ratio can be also kept as high as possible, because the block size or the center position are obtained on the basis of the result of the motion search of the unidirectional prediction.

  • Publication number: 20120301012
    Abstract: When super-resolution processing is applied to an entire screen image at the same intensity, a blur contained in an input image is uniformly reduced over the entire screen image. Therefore, the screen image may be seen differently from when it is naturally seen. As one of methods for addressing the problem, there is such a method that: when a first image for a left eye and a second image for a right eye are inputted, each of parameters concerning image-quality correction is determined based on a magnitude of a positional deviation between associated pixels in the first image and second image respectively; and the parameters are used to perform image-quality correction processing for adjusting a sense of depth of an image.

  • Patent number: 8221604
    Abstract: Transfer of fluid substances, and/or substances comprised in fluid substances, is controlled by introducing a separation medium, which prevents transfer of the fluid substances, and/or the substances comprised in the fluid substances, to an intermediate cavity connecting a first cavity and a second cavity; and introducing a connection medium to replace the separation medium and thereby start substance transfer to the second cavity. Substance transfer may be readily controlled without relying on mechanical means. Based on the present invention, two-dimensional electrophoretic analysis can be readily implemented on a chip.

  • Publication number: 20100069792
    Abstract: A biosensor cartridge capable of performing puncturing in an exact position, and easily collecting and measuring a sample of a puncture hole without requiring the operation of bringing a sample collection opening close to the puncture hole is provided. When tip portion 11a of biosensor chip body 11 is pushed against a subject M, elastic body 20 protruding from a tip portion 11a of biosensor chip body 11 is compressed, and puncturing tool 12 for puncturing protrudes. Thus, the subject M can be punctured. Additionally, if a pushing force is weakened, puncturing tool 12 is extracted from the subject M by the restoring force of elastic body 20, and the sample R flows out of the puncture hole. Additionally, cover member 19 is provided around biosensor chip body 11. Thus, when puncturing is performed by thin plate-shaped biosensor cartridge 10, biosensor chip body 11 can be prevented from deforming, and puncturing can be accurately performed in a desired puncturing position.

    Abstract: A biosensor cartridge capable of making the collected amount of a sample required for measurement into a small quantity to reduce a user's burden, and easily collecting and measuring a sample of a puncture hole without requiring the operation of bringing a sample collection opening close to the puncture hole is provided. When one end portion of biosensor chip is pushed against subject, elastic body is compressed, and puncturing tool can protrude and perform puncturing. Additionally, if a pushing force is weakened, puncturing tool is extracted from subject by the restoring force of elastic body, and blood (sample) flows out of the puncture hole. In this case, since the puncture hole, and sample collection opening provided at biosensor chip are contained in enclosed half-open space formed by elastic body, even a small amount of blood (sample) can also be easily collected.

  • Publication number: 20090299225
    Abstract: There is provided a biosensor chip where the collecting amount necessary for the measurement is made small whereby burden of a user is reduced and, at the same time, a sample at a puncture opening is able to be easily collected and measured without an operation of making the sample collection opening nearer the puncture opening. When an end of a main body chip is pushed onto a test body, an elastic body installed at an end of the main body chip is compressed and a device for puncture is produced whereby the test body is able to be punctured. When the pushing force is made weak, the device for puncture is pulled out from the test body due to resilience of the elastic body and a sample is flown out from the puncture opening.
