  • Publication number: 20130222925
    Abstract: A close-distance correcting lens system includes a positive first lens group and a negative second lens group, wherein traveling distances of the first lens group and the second lens group toward the object side differ from each other when carrying out a focusing operation on an object at infinity to an object at a close distance. The first lens group includes a positive first sub lens group, a negative second sub lens group, a diaphragm, and a positive third sub lens group, in that order from the object side. The second sub lens group includes an image-stabilizing lens group which is arranged to move in a direction orthogonal to the optical axis to change an imaging position of the object image to thereby correct any image shake of the object image.

  • Publication number: 20130201390
    Abstract: A dark exposure control device comprises a dark exposure performing processor, an aperture-stop, and an aperture-stop driving processor. The dark exposure performing processor detects an image signal generated by an imaging device while the shutter is closed. The aperture-stop adjusts the amount of light incident on the imaging device. The aperture-stop driving processor adjusts the opening degree of the aperture-stop to smaller than the opening degree set for a main exposure while the dark exposure performing processor is operated.

  • Publication number: 20130194442
    Abstract: A stage apparatus includes a stationary support plate, magnetic force generators immovable relative to the stationary support plate, a stage member, an image sensor fixed to the stage member, a control circuit board connected to a side of the stage member, and coils which produce a driving force upon a supply of electric current thereto, the coils being fixed to the stage member at an opposite side of the center of the stage member with respect to the control circuit board, and a FPC board between the stationary support plate and the stage member. The stationary support plate is recessed, from a lateral edge of the stationary support plate at which the control circuit board is provided, in a direction toward the coils and includes an FPC board escape recess, in which said FPC board is partially positioned.

  • Publication number: 20130194475
    Abstract: A digital camera includes an image sensor, a display device which displays a live-view display of an object image, an autofocus adjuster which detects a focal state and brings a specified object image into an in-focus state by moving a focal-adjusting lens group of a photographing lens, a focus lock-on device which prohibits the focal-adjusting lens group from moving and enters a focus locked-on state when the autofocus adjuster brings the specified object image into an in-focus state, a focus lock-on detector, and a distinguishing-display controller. When the focus lock-on detector detects a focus locked-on state, the distinguishing-display controller performs image processing on part or the entirety of the specified object image, and a peaking display of the specified object image is displayed on the display device.

  • Publication number: 20130195436
    Abstract: A diaphragm control apparatus is provided with a controller. When a photographing lens is attached to a camera body and a power switch is turned from ON to OFF, a drive motor first moves a diaphragm device to a minimum aperture, and thereafter the drive motor is switched from power ON to OFF. Thus, any damage to the inside of camera body due to sunlight entering into the opening of the diaphragm device can be prevented, and also the structure of camera body can be simplified by reducing the number of parts.

  • Publication number: 20130182404
    Abstract: A storage structure for a light-emitting device is included in a camera body, which also includes a lens mount formed on its front side for attaching a lens barrel and an imaging element arranged on its back side with a center thereof aligned with the center of the lens mount. The storage structure is a concave storage compartment arranged to correspond with an upper part of the lens mount. The light-emitting device is attached to the storage compartment and capable of popping up and down therefrom, the floor of the concave storage compartment is located between a lower edge of an engaging pawl, which is arranged at an upper edge portion of the lens mount, and the upper side of the imaging area of the imaging element.

  • Publication number: 20130136441
    Abstract: A movable mirror shock-absorbing mechanism of a camera includes a movable mirror which is rotatable between a viewfinder light-guiding position and a retracted position, a pressing portion which moves with the rotation of the movable mirror, a first shock-absorbing member which is pressed and moved by the pressing portion to absorb shock of the movable mirror when the movable mirror rotates from the retracted position to the viewfinder light-guiding position, and a second shock-absorbing member which is pressed and moved by the pressing portion to absorb shock of the movable mirror when the movable mirror rotates from the viewfinder light-guiding position to the retracted position. The first and second shock-absorbing members are mutually identical in specifications.

  • Publication number: 20130107103
    Abstract: A portable device has a display, a display processor displays a magnification image on a screen of the display, and an input device. The portable device further has a display-area shift processor that shifts the magnification-image-display area in accordance to an input operation administered to the input device, and a position sensor that detects an angle of inclination of the body. Then, The display processor changes the magnification-image-display area to an image area that is inclined by an angle corresponding to the angle of inclination, and the display-area shift processor changes shift directions of the magnification-image-display area from vertical and lateral directions of the original image to directions that are perpendicular to each other and correspond to inclined vertical and lateral directions rotated by the angle of inclination.

  • Publication number: 20130108257
    Abstract: A movable mirror shock-absorbing mechanism of a camera includes a mirror rotatable between a viewfinder light-guiding position and a retracted position, and a shock-absorbing member. The shock-absorbing member is held at a stand-by position with a pressure receiving portion thereof spaced from a contact portion provided on the mirror when the mirror is at the viewfinder light-guiding position or the retracted position. When the mirror rotates between the viewfinder light-guiding position and the retracted position, the contact portion presses the pressure receiving portion to move the shock-absorbing member against the biaser, the shock-absorbing member returns to the stand-by position after the pressing of the contact portion is released, and bouncing of the mirror is limited by a contact engagement between the contact portion and the pressure receiving portion.
