  • Publication number: 20140320432
    Abstract: A traffic information presentation system according to an embodiment is a system for presenting a tactile sensation to a user based on traffic information, including: a touch section; a tactile presentation section; an input section for receiving traffic information; and a control section for controlling the tactile presentation section based on the traffic information. The control section monitors a status of touch with respect to the touch section, and accepts an instruction from the user that corresponds to the touch input operation when detecting that an amount of change in touched position equals to or exceeds a certain amount. When detecting that the amount of change in touched position is less than the certain amount and that the touch duration equals to or exceeds a certain length, the control section causes the tactile presentation section to present a tactile sensation based on the traffic information.

  • Patent number: 8848302
    Abstract: The lens barrel includes a first lens unit, a second lens unit, and a drive unit. The first lens unit includes a first lens element and a first lens support frame supporting the first lens element. The second lens unit includes a second lens element and a second lens support frame supporting the second lens element. The second lens unit is supported by the first lens unit to be movable in the optical axis direction of the first lens element with respect to the first lens unit. The drive unit is arranged to be used to drive the second lens unit with respect to the first lens unit, and is fixed to the first lens unit. When viewed in the optical axis direction, the drive unit is fixed to the first lens unit so that a first profile line formed by the first lens unit and the drive unit is substantially circular.

  • Patent number: 8687285
    Abstract: An interchangeable lens unit comprises a second lens group unit, a focus lens unit, a fourth lens group unit, a zoom ring unit, and a focus motor. The zoom ring unit mechanically transmits operational force inputted to a zoom ring to the second lens group unit and the fourth lens group unit. The focus motor electrically drives the focus lens unit in the Z axis direction with respect to the second lens group unit. When the zoom ring is operated in a state in which no power is being supplied to the focus motor, a gap is always ensured in the Z axis direction between the focus lens unit and the second lens group unit.

  • Patent number: 8471945
    Abstract: There are provided an image display device and an imaging device with which efficiency can be improved in the comparison of a plurality of images. A digital camera includes a liquid crystal monitor, a body microcomputer, and an image display controller. The body microcomputer has a display manager and a selector. The liquid crystal monitor has a first display region and a second display region and is configured to display images recorded to a recording medium. The display manager is configured to manage as display objects one or more images that have yet to be displayed on the liquid crystal monitor in a specific mode. The selector is configured to select an image from among the display objects as a selected image for display on the liquid crystal monitor. The image display controller is configured to display the selected image in the first display region or the second display region.

  • Publication number: 20130070124
    Abstract: A lens barrel comprises a first zoom/focus lens group and a second zoom/focus lens group configured to respectively vary a focal distance and imaging distance by moving in an optical axis, a first actuator configured to drive the first zoom/focus lens group, a second actuator configured to drive the second zoom/focus lens group, and a drive controller configured to independently control the first actuator and the second actuator. The drive controller is configured to wobble the first zoom/focus lens group by reciprocating only the first zoom/focus lens group out of the first and second zoom/focus lens groups in a optical axis direction.
