  • Patent number: 8922619
    Abstract: Disclosed are an unmanned monitoring system and a monitoring method for performing 360° unmanned monitoring work in equipment having a low storage capacity, such as a robot, by using one omni-directional camera. When an image is input through the omni-directional camera, a movement of an object is detected from the image. Then, the movement region is sampled by tracing the object and the image for the movement region is rotated into a frontal image while compensating for inclination of the image in order to allow a user to easily view the image. Thus, the frontal image is transmitted to a mobile communication terminal of a user, such as a mobile phone or a PDA.

  • Patent number: 6438324
    Abstract: A pair of integration-type light-receiving sensors receive the light from subjects via a taking optical system and produce a subject image signal. A light projecting section projects light onto the subjects. A steady-state light removing section obtains an image signal by removing the steady-state light component from the subject image signal the pair of integration-type light-receiving sensors produces, while the light projecting section is projecting light onto the subjects. A first distance-measuring section measures a subject distance on the basis of the image signal obtained by causing the steady-state light removing section to remove the steady-state light component from the subject image signal. A subject select section causes the first distance-measuring section to make distance measurements for a specific time, performs operation on the resulting image signal using a specific correction function, and thereby selects a subject whose distance is to be measured.

  • Patent number: 5708882
    Abstract: A camera includes a display that displays in the viewfinder a photographic screen size even when the low consumption power supply mode is in use. The camera includes a power source, a controller, a film winding motor, a panorama frame driving motor, a CPU, an EEPROM, a viewfinder LCD and a timer. When the power switch is turned on, the CPU causes the panorama frame to move and changes the transmissivity of the viewfinder LCD to match the photographic screen size selected the largest number of times. When a new photographic screen size is selected using the photographic screen size switch, the number of times the photographic screen size has been selected is calculated and stored in the EEPROM. In addition, the time that has elapsed after the power switch has been turned on is measured by the timer, and when the time exceeds a predetermined value, the camera moves into the low consumption power supply mode with power still being supplied to the viewfinder LCD.

  • Patent number: 5678104
    Abstract: A variable field size shooting camera includes a mechanism for varying the size of the shooting field between at least two sizes. The switching between sizes is accomplished by providing a pair of light shielding members that enable a change of field size. The light shielding members are positioned between a shutter having a cover plate and the body having the exposure aperture unit. Moving of the light shielding members is achieved by a switching mechanism. The light shielding members are attached to a support member on the front surface of the body to support the light shielding members so the light shielding members move freely. A clear image is obtained by having a space between the body having an exposure aperture unit and the light shielding member virtually non-existent. This minimizes the blurring of subjects in the surrounding area of the field during a large size shooting.

  • Patent number: 5678100
    Abstract: The present invention discloses a mounting structure for dousers allowing a photographic camera to be selectively operated in a PANORAMA MODE, characterized in that an aperture frame is provided separately of a camera body so as to be mounted on the camera body from behind and to pivotally carry the dousers. The structure, according to the invention, facilitates operation of mounting the dousers and, in addition, makes a telescopic lens barrel retractable into the camera body as deeply as possible. The dousers are pivotally supported by fork-shaped support means provided on the front side of the aperture frame so that the dousers may be pivotally moved toward or away from upper and lower zones of the aperture. The aperture frame is detachably mounted on the rear side of the camera body from behind so that output means of a drive mechanism for the dousers are operatively associated with the dousers as the aperture frame is thus mounted on the camera body.

  • Patent number: 5652932
    Abstract: When a switching control on an outer wall of a camera is operated and stopped at a click groove corresponding to a desired aspect ratio (for example, C), a CHP lever moves up together with the switching control, and the displacement of the CHP lever is transmitted to an axis rotating lever via a spring. A rotational stroke of the axis rotating lever is smaller than a moving stroke of the CHP lever. A displacement of the CHP lever exceeding the rotational stroke of the axis rotating lever is absorbed by the deformation of the spring. The axis rotating lever is positioned steadily at one of ends of the stroke by the elastic force induced by the deformation of the spring. As a result, the ends of stroke holes in visual field frame pieces can abut against positioning pins without fail.
