  • Publication number: 20080067894
    Abstract: An ultrasonic rotary drive device includes an ultrasonic motor including an ultrasonic generating portion and a first rotary output portion, wherein the first rotary output portion is in contact with the ultrasonic generating portion to be rotatable relative to the ultrasonic generating portion and rotates by ultrasonic vibrations generated by the ultrasonic generating portion; and a one-way rotational transfer mechanism including a rotary input portion and a second rotary output portion. The rotary input portion rotates with the first rotary output portion. The second rotary output portion is rotatable independently of the rotary input portion. Rotation of the rotary input portion is transferred to the second rotary output portion when the rotary input portion is rotated. Rotation of the second rotary output portion is prevented from being transferred to the rotary input portion when the second rotary output portion is rotated.

  • Publication number: 20080062277
    Abstract: A photographing apparatus comprises an imaging sensor, a controller, and an exposure-mode-selecting device. The controller performs a photometric operation on a photographing subject and obtains a luminance value of the photographing subject based on the photometric operation. The exposure-mode-selecting device is used for selecting an exposure mode of the photographing apparatus that has a shutter speed and aperture priority AE mode. The photographing operation is performed with a shutter speed and an aperture value that are set by a user and a sensitivity of the imaging sensor that is calculated based on the luminance value and the shutter speed and the aperture value, while the photographing apparatus is in the shutter speed and aperture priority AE mode.

  • Publication number: 20080063306
    Abstract: An indicating apparatus comprises a display unit and a controller. The display unit indicates a first image and a second image. The controller controls the display unit. When the second image is indicated after an enlargement indication of a part of the first image as a first enlargement indication area is performed, the controller specifies a first position relationship between the first enlargement indication area and the first image, and performs the enlargement indication of the second image on the basis of the first position relationship. The controller specifies the first position relationship by obtaining a second position relationship between a base point in the first enlargement indication area and a range of movement of the base point in the first image.

  • Publication number: 20080064922
    Abstract: A color image pickup and display device that can be simply structured and provided at a low price. A lighting source irradiates lights of primary colors in a manner capable of being switched in a predetermined sequence. Monochrome solid-state image sensors are used as image pickup means, while a backlight type monochrome LCD element is used as a display of a display device. The LCD element can switch the color of backlight to the same color as that of the lighting source synchronously with the switching of color thereof. Thus, the backlight can emit light of the same color as that of the light emitted by the lighting source when the picture signals outputted by the sensors in response to the image observed by the light of the lighting source are displayed by the LCD element.
