  • Publication number: 20180349696
    Abstract: A line-of-sight analysis method, performed by a computer, includes: identifying, when a selection event with respect to a first object out of a plurality of objects is detected, a second object different from the first object, based on a detection status of line-of-sight relative to the objects in a most recent time period of the selection event; and outputting information indicating the identified second object.

  • Publication number: 20180337076
    Abstract: Nitrogen gas supplied from the outside of a chamber flows into an annular first buffer to diffuse uniformly along the circumferential direction of a gas ring. The nitrogen gas filled in the first buffer flows into a second buffer with having a volume larger than that of the first buffer to diffuse more uniformly along the circumferential direction of the gas ring. The nitrogen gas filled in the second buffer flows into a labyrinth portion to flow through a bent flow path of the labyrinth portion from the inside toward the outside along the radial direction of the gas ring, so that a flow rate of the nitrogen gas decreases. The nitrogen gas flowing out of the labyrinth portion flows into a discharge flow path, and flows from the outside toward the inside along the radial direction of the gas ring to be discharged from the gas discharge opening.

  • Patent number: 9473696
    Abstract: A gaze detection apparatus includes a light source which illuminates a user's eye, an imaging unit which generates an image by capturing the image of a user's face, and a processor adapted to: estimate a distance between the imaging unit and the user's face; calculate the ratio of the distance between the imaging unit and the user's face to a separation distance between the imaging unit and the light source and determine, based on the ratio, whether a bright pupil phenomenon occurs; detect from the captured image a corneal reflection image of the light source and a center of the user's pupil when determining that the bright pupil phenomenon does not occur; and detect the user's gaze direction or gaze position based on a positional relationship between the center of the user's pupil and the corneal reflection image when determining that the bright pupil phenomenon does not occur.

  • Patent number: 9042642
    Abstract: A determining unit determines which one of a plurality of divided areas in color distribution a value of an input image single falls within. The plurality of divided areas are defined for each of R, G, and B color components, and the determining unit determines, for each color component, which one of the plurality of divided areas the value of the input image signal falls within. An image correcting unit reads correction coefficients corresponding to the determined divided area for each color component from a correction coefficient storing unit in which correction coefficients are registered for each of the color components and each of the divided areas. The image correcting unit calculates each of R, G, and B output values of an output image signal using the correction coefficients of the individual color components read from the correction coefficient storing unit.

  • Patent number: 8810694
    Abstract: A memory unit stores as conversion information which is derived based on a correction coefficient which provides, in a predetermined allowable range from a minimum value, a sum of a norm of a difference between a color difference of a correction target color and a target color which is a target of correction of the correction target color and a correction color obtained by correcting the correction target color using the correction coefficient, and a norm of the correction coefficient to which a predetermined weight coefficient is applied. A color correcting unit converts a color of each pixel of an image captured by an image capturing unit based on the conversion information.

  • Publication number: 20110311839
    Abstract: A manufacturing method for a magnetic recording medium includes forming a magnetic layer on a base material, forming a recording layer having a textured pattern of the magnetic layer by forming a recessed portion that passes through the magnetic layer, depositing an oxidizing material or a nitriding material on the inner surface of the recessed portion while leaving a space in the recessed portion, packing the space with an oxide material or a nitride material by oxidizing or nitriding the deposited material, and planarizing by removing excess oxide material or nitride material on the recording layer.

  • Patent number: 7672074
    Abstract: A thermally assisted magnetic recording method includes the following steps. The recording layer of a magnetic recording medium is irradiated with a laser beam to produce a locally heated region. This heated region is moved by causing the recording layer and the laser beam to move relative to each other. To record desired information, a recording magnetic field is applied to the heated region of the recording layer. The laser beam has a cross section elongated in the direction in which the heated region is moved.

  • Patent number: 7561360
    Abstract: A magnetic recording medium includes a substrate and a recording layer formed on the substrate.
