  • Publication number: 20130113898
    Abstract: Disclosed is an image capturing apparatus which is capable of obtaining a three-dimensional image in either a vertical or horizontal position. The image capturing apparatus is provided with two imaging elements, and an image processing portion which uses the images imaged by the imaging elements to generate a three-dimensional image. The image processing portion calculates the parallax between a first and a second image, imaged by the imaging elements, and uses the first image to generate an estimated image having parallax in the direction orthogonal to the arrangement direction of the imaging elements, relative to the first image, and generates a three-dimensional image from the calculated parallax and the estimated image.

  • Publication number: 20080187368
    Abstract: A drum unit (20) for forming a toner image includes a cylindrical-shaped metal tubular member (31), a flange member (40) attached to one end of the metal tubular member (31) and a ground plate (50) attached to the flange member (40) and having an outer peripheral edge formed with a connection claw (52) that is so bent by the inner peripheral surface of the metal tubular member (31) as to bite into the inner peripheral surface for establishment of electrical conduction between the metal tubular member (31) and the ground plate (50). The flange member (40) has an edge, and the bending of the connection claw is carried out about a support point (412) defined by the edge. A calculational bending angle (?) at which the connection claw (52) is bent about the support point (412) is set in the range of 10 to 45 degrees.

  • Publication number: 20070200473
    Abstract: The invention is to provide a simple and compact configuration which can still be improved in the efficiency of light condensation to a predetermined small-diametric area. The present invention is a device comprising: an arc tube 20 having a pair of main electrodes 21 and 22; and a reflector 30 for reflecting the outgoing light emitted from the arc tube 20, the electrode axis O1 of the main electrodes 21 and 22 being arranged to cross the light axis LA of the outgoing light. The reflector 30 is formed of a first reflector portion 31 having a spherical surface centered at the light generation point L0 of the arc tube 20 and a second reflector portion 32 having a curved surface different from the first reflector portion 31, and a condenser 40 that condenses the outgoing light emitted from the arc tube 20 to other than the second reflector portion 32 and illuminates the condensed light in a predetermined direction or to a predetermined area is provided.

  • Publication number: 20070041197
    Abstract: A concave mirror substance 1 constituting a reflector is composed of a base material having a high thermal conductivity such as aluminum etc. An infrared-to-heat converting layer 2 is film-formed by anodizing the substrate formed of aluminum etc., so as to absorb light in a wavelength range which passes through a visible light reflecting layer 4 and convert it into heat. A gloss-forming buffer layer 3 is film-formed by calcining Si resin or polyimide resin over the inner side (the light source-side surface) of infrared-to-heat converting layer 2 at high temperatures, so as to buffer the two layers in a manner that does not allow infrared-to-heat converting layer 2 and visible light reflecting layer 4 to be in direct contact with each other, and so as to reduce the influence of projections and indentations present on infrared-to-heat converting layer 2 and smoothen the light source-side surface of visible light reflecting layer 4.
