  • Patent number: 8773575
    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.

  • Patent number: 8761460
    Abstract: A method of automatically tracking and photographing a celestial object, which moves due to diurnal motion, while moving an imaging area on an imaging surface of an image sensor so that an image of the celestial object becomes stationary, includes calculating theoretical linear movement amounts and a theoretical rotational angle amount of the imaging area per a specified time; obtaining a movable-amount data table which stores data on actual linearly-movable amounts and an actual rotatable amount of the imaging area; and setting an exposure time for completing a celestial-object autotracking photographing operation while moving the imaging area within the range of movement thereof by comparing the theoretical linear movement amounts and the theoretical rotational angle amount with the actual linearly-movable amounts and the actual rotatable amount of the imaging area stored in the movable-amount data table.

  • Patent number: 8753024
    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.

  • Patent number: 8731327
    Abstract: An image processing system performs a position-matching operation on first and second images, which are obtained by photographing the same object a plurality of times. A plurality of shift points are detected in the second image. The shift points correspond to fixed points, which are dispersed throughout the whole of the first image. The second image is divided into a plurality of partial images, the vertices of which are positioned at the same coordinates as the fixed points in the first image. Each of the partial images are shifted to the shift points to transform the partial images so that corresponding transformed partial images are produced. The transformed partial images are combined to form a combined image.

  • Patent number: 8717441
    Abstract: A method of automatically tracking and photographing a celestial object so that the celestial object image, which is formed on an imaging surface of an image sensor via a photographing optical system, becomes stationary relative to a predetermined imaging area of the imaging surface of the image sensor during a tracking and photographing operation. The method includes performing a preliminary photographing operation at a predetermined preliminary-photographing exposure time with the photographic apparatus directed toward the celestial object and with a celestial-body auto tracking action suspended to obtain a preliminary image before automatically tracking and photographing the celestial object, calculating a moving direction and a moving speed of the celestial object image from the preliminary image that is obtained by the preliminary photographing operation, and automatically tracking and photographing the celestial object based on the moving direction and the moving speed of the celestial object image.

  • Patent number: 8699869
    Abstract: Optical equipment which can prevent image blurring and enable a lens to be stopped in a position requiring low power consumption is provided. The optical equipment includes a lens driver supplied with electric power from a camera body to drive a focusing lens. The equipment further includes an aperture driver that drives an aperture and a drive controller that positions the focusing lens to minimize power consumption and controls the aperture driver during opening of the aperture so that the focal position of the focusing lens falls within a focal depth. In this way, a lens position-controller that controls an AF motor can stop the lens in a position that does not cause image blur and reduces power consumption.
