  • Publication number: 20100141764
    Abstract: A parameter selection section selects one from a plurality of image synthesis parameters stored in a parameter storage section according to an output of a vehicle state detection section. An image synthesis section reads out camera images from frame memories according to the selected image synthesis parameter and generates a synthesized image showing a state of vehicle surroundings. A moving object detection section detects, in the thus generated synthetic image, a moving object region estimated as a region where a moving object is present.

  • Publication number: 20090082367
    Abstract: [Problem] To provide a compound which may be used in treating diseases in which 11?-hydroxysteroid dehydrogenase type 1 (11?-HSD1) is concerned, especially diabetes and insulin resistance. [Means for Solution] It was found that a triazole derivative or a pharmaceutically acceptable salt thereof, in which the 3-position of triazole ring is substituted with a trisubstituted methyl group and the 5-position is substituted with a lower alkyl, cycloalkyl or the like, has a strong 11?-HSD1-inhibitory activity. In addition, since the triazole derivative of the present invention shows excellent blood glucose-lowering action, it may be used in the treatment of diabetes and insulin resistance.
