  • Patent number: 7826732
    Abstract: A stage apparatus includes a stationary support plate; a stage member provided on the stationary support plate so as to move on a reference plane parallel with the stationary support plate; Y-direction magnetic flux generating devices secured to one of the stationary support plate and the stage member; and Y-direction moving coils secured to the other of the stationary support plate and the stage member, the Y-direction moving coils receiving magnetic flux from the Y-direction magnetic flux generating devices so as to generate a driving force in a specific Y-direction between the Y-direction magnetic flux generating devices and the Y-direction moving coils. The Y-direction moving coils are secured to the stage member so that the Y-direction moving coils at least partly overlap each other in an X-direction, which is parallel with the reference plane and perpendicular to the Y-direction, and do not overlap in the Y-direction.

  • Publication number: 20080145041
    Abstract: An anti-shake apparatus for image stabilization of a photographing apparatus comprises an imaging sensor, an acceleration sensor, and an inclination degree output unit. The imaging sensor has an imaging surface on which an optical image through a photographing optical system of the photographing apparatus is captured. The acceleration sensor detects a first gravitational acceleration component in a direction of a first detection axis and a second gravitational acceleration component in a direction of a second detection axis. The first detection axis and the second detection axis are perpendicular to an optical axis of the photographing optical system. The inclination degree output unit outputs information regarding an inclination angle caused by a roll of the photographing apparatus about the optical axis, based on the first gravitational acceleration component and the second gravitational acceleration component.

  • Patent number: 7221394
    Abstract: A digital camera comprises a solid state imaging device provided with an optical low-pass filter. A photographing optical system forms an object image on a light receiving surface of a CCD through the optical low-pass filter. An electronic-charge accumulation-time control program is stored in a ROM of a system control circuit to determine optimum exposure parameters according to which a photography is performed. The electronic-charge accumulation-time control program has a program diagram showing a relationship between an electronic-charge accumulation-time and an aperture value and/or an ISO speed.
