  • Patent number: 10481677
    Abstract: An adequate display operation control in accordance with the external world situation is realized. For example, where a user wears the wearing unit of a spectacle-shaped or head-worn unit, the user is made to be able to view any type of image on the display section immediately in front of the eyes, and provided with taken images, reproduced images, and received images. At the point, a control relative to various display operations such as on/off of the display operation, display operation mode, and source chage is carried out based on external world information.

  • Patent number: 8896701
    Abstract: An active infrared sensor may include an imaging infrared sensor to provide an output signal conveying time-sequential infrared images of a scene which includes a subject, a beam generator to generate a millimeter wave energy beam, and a processor. An initial infrared image of the scene may be stored in a memory. After storing the initial infrared image, the beam generator may illuminate the subject with the millimeter wave energy beam. A temperature change across the subject due to the millimeter wave energy beam may be estimated based on the output signal and the stored initial infrared image. The beam generator may stop illuminating the subject when a highest temperature change across the subject is at least equal to a predetermined temperature change limit.

  • Patent number: 8669876
    Abstract: An above-water system provides automatic alerting for possible drowning victims in swimming pools or the like. One or more electro-optical sensors are placed above the pool surface. Sequences of images are digitized and analyzed electronically to determine whether there are humans within the image, and whether such humans are moving in a manner that would suggest drowning. Effects due to glint, refraction, and variations in light, are offset automatically by the system. If a potential drowning incident is detected, the system produces an alarm sound, and/or a warning display, so that an operator can determine whether action must be taken.

  • Patent number: 8599264
    Abstract: Methods for comparing infrared image data and/or for generating infrared image comparison data are provided. In one method two image data sets are selected including visual-light and infrared image data from one or more points of view of a scene. Visual-light image data from each data set can be compared to determine an alignment correlation between different points of view for the visual-light data. The alignment correlation can then be used to correlate infrared image data from each data set. The correlated infrared image data can be compared to generate infrared comparison image data. Thermal imaging cameras capable of performing such methods are also provided.

  • Patent number: 8587656
    Abstract: A face camera mount structure in a vehicle has a camera for imaging a driver's face being disposed on a reverse side of a dial at a portion that does not interfere with a speedometer design portion on the dial. A camera facing portion of the dial that faces a lens of the camera is covered with a print of a near-infrared light passing ink that selectively passes a near-infrared light. The high transparency factor of the near-infrared light through the ink makes it possible for the camera to image a sufficiently bright near-infrared light image without being recognized by a driver of the vehicle.

  • Patent number: 8098282
    Abstract: The present invention advantageously provides a means by which the privacy zone on a PTZ camera can be maintained so that an object in the camera's sight is always masked or covered. An algorithm which remembers the defined privacy zones as an area in space marked by four rays touching the four corners of the marked zone and having absolute Pan, Tilt angular coordinates is presented. The privacy zone is initially defined by a rectangle on the screen with known pixel co-ordinates which are translated into angular coordinates. Then, when the camera moves and prepares to display a new screen, the privacy zone is superimposed on the object to be masked. Locating the object and displaying its privacy zone is done by translating the absolute angular coordinates of the original privacy zone into pixel coordinates. Additionally, multiple privacy zones can be displayed on one camera screen.

  • Patent number: 7663687
    Abstract: A digital cinema camera includes a plurality of imagers and a plurality of shutters mounted radially on a frame. A beam splitter disposed at a center of the frame rotates to provide an input optical beam sequentially to the plurality of imagers. When the input optical beam is aligned with a particular one of the imagers, a corresponding one of the shutters is triggered to apply the optical beam on the particular one of the imagers. The electrical signals generated by the imagers are first stored in RAM, and then transferred to a hard disk drive disposed in a removable magazine. This way, the magazine can be replaced with a new magazine, and the latent image data can be downloaded out of the removed magazine for post-processing while new image data is being stored in the new magazine.

  • Patent number: 6621600
    Abstract: A scanner is provided with a variable aperture lens system. High resolution scans use a relatively small aperture size, and scanning speed is relatively slow. Low resolution scans use a relatively large aperture size, and scanning speed is increased. Fast scans are limited to lower sampling rates, which in turn permit more optical blurring relative to high sampling rates. Accordingly, the incremental cost of the larger aperture is minimized by permitting the lens aberrations specifications to be relaxed at larger apertures. Preferably, an electronic variable aperture is provided, for example, by use of electronically controlled polarization plates or by use of electrochromic substances.

  • Patent number: 6449012
    Abstract: The present invention has an object of realizing highly reliable search with high precision by obtaining a clear view image over a wide view. In particular, a reflection mirror is formed so as to correspond to an image pick-up element at a focus surface of a converging lens of an image pick-up camera and the image pick-up camera is arranged to be capable of freely performing scanning by a scanning mechanism portion. As a result, with the image pick-up camera kept performing linear scanning, the reflection mirror performs triangular scanning in a direction opposite to the scanning direction of the image pick-up camera for every frame cycle T and a light wave taken in by the converging lens is introduced to the image pick-up element for every one frame, thereby to obtain a static view image. The desired object is thus achieved.

    Abstract: A thermal infrared imaging device (10) includes a thermal detector (50) having a linearly-arrayed plurality of spaced apart detector elements (50', 50", 50"', . . . ). A scene to be viewed is scanned across the detector (50) with successive fields of the scene shifted according the spacing between adjacent detector elements (50', 50", 50"', . . . ) in order to capture image information for the entire scene by interlacing of successive scan lines from the plurality of detector elements (50', 50", 50"', . . . ). Each complete scan of the viewed scene across the detector (50) creates an image field including a scan line for each detector element (50', 50", 50"', . . . ). Each scan line includes plural pixels, or picture elements of the viewed scene, each having a value indicative of the thermal infrared brightness of the viewed scene at the corresponding location along the scan line. An scan-line sum for each scan line is created by adding the absolute values of the pixel values for each scan line.
