Optical Path Switching Patents (Class 348/344)
  • Patent number: 8547473
    Abstract: A surrounding area is imaged onto a detector of a detector device. An optical system produces an imaging beam path and a panel, which is arranged in the imaging beam path, shadows a subarea of the image of the surrounding area on the detector. In order to mask out an object which would dazzle the detector device, while nevertheless being able to monitor the surrounding area, the panel is illuminated in a subarea, and the transmission of the panel in the subarea is reduced by the illumination in the entire frequency range in which the detector is sensitive. The illuminated subarea of the panel shadows the selected subarea of the image.

  • Patent number: 8319882
    Abstract: A phase-difference detecting image pickup element performs focus detection even if the position of an exit pupil with respect to the image pickup element changes. A pixel pair receives an object light beam transmitted through a pair of portion areas whose areas become the same in an exit pupil at a particular distance from the image pickup element. The pixel pair includes light-intercepting portions that define the pair of portion areas. A different pixel pair whose light-intercepting portions are different so that the areas of the pair of portion areas in the exit pupil the particular distance from the image pickup element are the same. By this, even if the position of the exit pupil is changed by, for example, a lens replacement, focus detection can be performed by a phase-difference detection method by selecting a pixel pair in accordance with the position of the exit pupil.

When an angle of view is switched from a wide-angle to a narrow-angle, range display is performed for a predetermined time prior to the switching. Range display includes a narrow-angle image frame formed with lines indicating a border of an image displayed for a predetermined time prior to the switching. After the predetermined time, a narrow-angle image is displayed and the range display is no longer displayed.

  • Patent number: 8199244
    Abstract: A new digital image/video camera that directly acquires random projections of the incident light field without first collecting the pixels/voxels. In one preferred embodiment, the camera employs a digital micromirror array to perform optical calculations of linear projections of an image onto pseudorandom binary patterns. Its hallmarks include the ability to obtain an image with only a single detection element while measuring the image/video fewer times than the number of pixels or voxels—this can significantly reduce the computation required for image/video acquisition/encoding. Since the system features a single photon detector, it can also be adapted to image at wavelengths that are currently impossible with conventional CCD and CMOS imagers.

  • Patent number: 7734170
    Abstract: There is provided an imaging apparatus having a viewfinder optical system; a first image sensor; a photometric sensor; and optical path changing means. The viewfinder optical system has a first reflective surface that reflects a monitoring luminous flux, and the first reflective surface changes a reflection angle of the monitoring luminous flux. A change in a reflection angle of the first reflective surface causes a course of the monitoring luminous flux to be switched between a first optical path and a second optical path. In a case of second optical path, a travel direction is changed with the optical path changing means placed on the second optical path, causing a photometric processing to be performed using the first image sensor, while in a case of the first optical path, the photometric processing is performed using the photometric sensor.

  • Patent number: 7665912
    Abstract: An image-taking apparatus is disclosed which comprises an image-pickup device, an image processing unit, a display unit, a focus detection unit which detects a focus state of the image-taking lens, and an optical path splitting unit which is switchable between a first state in which it is disposed in an optical path from the image-taking lens and a second state in which it is retracted from the optical path. The optical path splitting unit transmits part of the light from the image-taking lens toward the image-pickup device and reflects the remaining part of the light toward the focus detection unit in the first state. A control unit performs focus control based on the detection result of the focus detection unit. The control unit performs the focus control in the first state such that an image-forming position matches a light-receiving surface of the image-pickup device in the second state.

  • Patent number: 7656454
    Abstract: An image pickup apparatus includes a finder optical system capable of guiding an observation beam to a finder window, the observation beam being a beam traveling from a photographing optical system and reflected by a main reflecting surface; and a first image pickup device configured to detect the observation beam and generate an image signal. The finder optical system has a first reflecting surface that reflects the observation beam. The first reflecting surface can change a reflection angle of the observation beam. A path of the observation beam can be switched between a first optical path and a second optical path by changing the reflection angle of the first reflecting surface. The first optical path is reflected by the first reflecting surface and directed toward the finder window, while the second optical path is reflected by the first reflecting surface and directed toward the first image pickup device.

    Abstract: A digital camera of the present invention includes a microcomputer 110 having a live view mode controlling so that image data generated by a CMOS sensor 130 or image data obtained by subjecting the image data generated by the CMOS sensor 130 to predetermined processing is displayed on a liquid crystal monitor 150 as a moving image in real time, wherein when a release button 141 receives an instruction regarding start of an autofocus operation in a live view mode, the microcomputer 110 controls a movable mirror to enter an optical path to measure by an AF sensor 132, and thereafter, allow the movable mirror to retract from the optical path to return the digital camera to the live view mode. Due to this configuration, in a digital camera that includes a movable mirror and is capable of displaying a subject image in a live view through an electronic viewfinder, the operability thereof can be enhanced.

  • Patent number: 7623177
    Abstract: In a digital camera having multiple optical systems, multiple image capturing elements are effectively driven to reduce power consumption. A digital camera has a first image capturing optical system having a lens and a first image sensor and a second image capturing optical system having a lens and a second image sensor. A controller and timing generator selects the image signal from the first image capturing optical system while controlling an operation or power of the second image sensor and a clock driver to be OFF when the zoom position falls within a first zoom range. When the zoom position falls within a second zoom range, the image signal from the second image capturing optical system is selected while an operation or power of the first image sensor and a clock driver is controlled to be OFF. An operation or power of the image capturing optical system which is not selected is stopped so that power consumption is reduced.

The light beam reflected by the second mirror is reflected by a third mirror in a direction opposite to that of the light beam reflected by the quick return mirror, and is also reflected by a fourth mirror toward an eyepiece side in the back side of the body unit. Some light beam components reflected by the half mirror are fetched by an AF sensor unit to detect the focal point position of the photographing lens.
