| 20090119583 | IMAGE DISPLAYING APPARATUS, IMAGE DISPLAY METHOD, AND IMAGE DISPLAY SYSTEM - An attribute determining unit determines an attribute of image data of an image. A still-image extracting unit extracts, when the attribute is a moving image, a still image from the image data. A feature-amount obtaining unit obtains a feature amount from image data of the still image and image data of a still image when the attribute is the still image. An arrangement-position determining unit determines an arrangement position of a display area based on the feature amount. A display-image generating unit generates a thumbnail image from the still image and displays a list of thumbnail images in the display area, based on the arrangement position and the display area. | 05-07-2009 |
| 20090119585 | IMAGE DISPLAY APPARATUS, IMAGE DISPLAY METHOD, IMAGE DISPLAY PROGRAM AND RECORDING MEDIUM - A disclosed image display apparatus for displaying multiple images on a single screen includes a magnification unit configured to, in response to a zooming operation on the screen, magnify distances between centroids of first group images included in the multiple images and magnify the first group images; and a display control unit configured to display in a space of the magnified distances one or more images different from the multiple images. A magnification rate of the distances between the centroids has a nonlinear relationship to a magnification rate of the first group images, and within an extent of the nonlinear relationship, the magnification rate of the distances between the centroids has a predetermined range in which the magnification rate of the first group images is larger than the magnification rate of the distances between the centroids. | 05-07-2009 |

| 20080204714 | ON-VEHICLE FUEL PROPERTY DETECTION DEVICE - The detection device provides with an optical fiber composed of a core, a clad and a fiber jacket. A grating is applied to the core, and the fiber jacket located at the portion to which the grating is applied is removed so that the clad is in contact with a fuel fed to an injector of a vehicle. The detection device also provides with a light source for incidence of a light in a range of clad mode wavelength to the optical fiber, and a light-sensitive part for detecting an intensity of the light transmitting through the region to which the grating is applied. The optical fiber, light source and light-sensitive part are held in a conduit disposed in a fuel tank or between a fuel pump and the injector of the vehicle. | 08-28-2008 |
| 20100080502 | OPTICAL FIBER SENSOR - An optical fiber sensor measuring refractive index of a medium with high sensitivity in a wide range. The optical fiber sensor includes an optical fiber causing a transmission loss due to leakage in the clad propagation mode from a portion of a core and a clad where a Bragg grating is provided, a light source permitting light in a wavelength band in the clad propagation mode to enter the optical fiber, and a light-receiving section receiving the transmitted or reflected light transmitted through the core and the clad at the portion where the Bragg grating is provided. The refractive index of the medium to be measured in contact with the clad is measured according to total intensity of the light received by the light-receiving section. The Bragg grating is inclined at a predetermined angle of inclination to the vertical line vertical to the length direction of the optical fiber. | 04-01-2010 |

| 20100296080 | OPTICAL FIBER SENSOR - An objective of the present invention is to provide an optical fiber sensor which has a simple configuration to enable sensitively measuring a refractive index of a measurement medium in a wide range of refractive indexes. An optical fiber sensor according to the present invention includes; an optical fiber having a core in which a short-period gratings are formed and a cladding, the optical fiber being made so that transmission loss occurs due to cladding-propagation-mode leakage at its cladding portion where the short-period gratings are formed; a light source from which light having a wavelength range of the cladding propagation mode is emitted; and a light receiving unit for receiving transmission or reflection light having passed through the cladding at the position where the short-period gratings are formed. The optical fiber sensor detects, based on the total receiving light intensity that the light receiving unit receives, the refractive index of the measurement medium contacting the cladding, in which the optical fiber is multi-mode one, and the short-period gratings have plural kinds of periods. | 11-25-2010 |
