  • Patent number: 8934713
    Abstract: An image processing device includes: a coordinate conversion unit (142) which calculates a corresponding sampling coordinate on a color mosaic image corresponding to a pixel position of a color image when a deformation process is performed, according to the pixel position of the color image; a sampling unit (143); a sampling unit (143) which interpolates-generates a pixel value in a sampling coordinate for each of color planes obtained by decomposing the color mosaic image; and a color generation unit (144) which generates a color image by synthesizing interpolation values of the respective color planes. Each pixel value of a color image subjected to a deformation process is obtained as a pixel value of the sampling coordinate from the color mosaic image by interpolation calculation, thereby realizing the color interpolation process for generating a color image from the color mosaic image and a deformation process of the color image by one interpolation calculation.

  • Publication number: 20140236012
    Abstract: Ultrasound diagnosis apparatus is provided which easily recreates test conditions same as the past, comprising scanner, signal processor, display controller, storage, detector, collator, and controller. Scanner scans a subject with ultrasound waves through ultrasound probe. Storage previously stores first relevant information in which operation of the scanner, the signal processor, or the display controller in past test is related to a first relative position which is the relative position of ultrasound probe for the subject in the same past test. Detector detects a second relative position which is the present relative position of ultrasound probe for the subject. Collator collates the first relative position and the second relative position detected by the detector. Controller controls the scanner, the signal processor or the display controller based on the operation related to the first relative position, when the first relative position and the second relative position are matched in collation.

  • Patent number: 8809557
    Abstract: Disclosed is a method of producing an optically active fluorinated oxetane, which can be an important pharmaceutical or agricultural intermediate, by reaction of a fluorinated ?-keto ester with an acyl alkenyl ether in the presence of a transition metal complex with an optically active ligand. This method utilizes a catalytic asymmetric synthesis process and does not require a stoichiometric amount of chiral source. It is thus possible to dramatically reduce the amount of use of the asymmetric catalyst especially when the reaction is performed at a high concentration of substrate (with the use of a small amount of reaction solvent) or in the absence of a reaction solvent (under neat conditions). Further, the target optically active fluorinated oxetane can be obtained with high yield and with very high optical purity. The product contains almost no difficult-to-separate impurity and shows high chemical purity.
