  • Patent number: 6882798
    Abstract: An optical transmission apparatus implemented as an OADM (Optical Add/Drop Multiplexer) includes quality monitors each for monitoring the quality of a signal arriving on a particular optical transmission path. A monitor/control unit converts quality signals output from the quality monitors to path-by-path bit error rates, or estimation values, and compares them to select a route. The monitor/control unit then generates a metric value “1” for the route selected and adds it to one of identical metric values, which are assigned to routes to the same destination, that corresponds to the route selected. The monitor/control unit can therefore select a route closer to actual transmission path conditions. A method of determining an optimal route for optical transfer is also disclosed.

  • Patent number: 6081350
    Abstract: An imaging and recording apparatus for electrically recording an optical image of a subject as an image information signal which facilitates memory access from an external device and prevents image information from being changed. Upon manipulation of a recording trigger switch, an image outputted from a camera signal processing circuit at that time is written into a semiconductor memory, then subjected to data compression in a data compression circuit, and stored in a semiconductor memory. It is now assumed that an external device not illustrated is connected to a connector and this external device orders taking in the image of the semiconductor memory. If at this time the semiconductor memory is writing an image, a state detection circuit detects the fact and inhibits the external device from taking in the image. Furthermore, while the external device is taking in the image of the semiconductor memory, the state detection circuit detects this fact.

  • Patent number: 5903706
    Abstract: An upside-down image, generated when a video camera is rotated about a horizontal axis to face to substantially the same direction as a display unit does, is electrically corrected to be an upright image. A video camera unit made compact to realize a reduction in weight of a video camera rotating mechanism. An image arrangement convertor circuit is provided between the video camera unit and a liquid crystal display serving as a display unit or a recording unit. A switch is provided in a housing for detecting an angular position of the video camera unit. The video camera, which has an imager device and a lens, is pivoted on an edge of the housing for rotation about an axis parallel to the edge. The image arrangement convertor circuit is operated unitarily in accordance with an angular position of the video camera to automatically correct an upside-down image to an upright image.
