    摘要： In an optical filter module and an optical amplification apparatus for a wavelength division multiplex (WDM light), the respective wavelength intervals of the plural passing center wavelengths and the filter characteristics in the vicinities of the respective center wavelengths can be set independently, whereby the BPF1 is provided with different passing center wavelengths .lambda.1, .lambda.2 . . . .lambda.n and different filter characteristics. And, when the WDM signal light including wavelengths .lambda.1, .lambda.2 . . . .lambda.n is inputted into the port 2-1a, the .lambda.k (k=1,2 . . . n) component is transmitted by the corresponding BPF1-k, and the transmitted light is multiplexed sequentially and outputted from the port 2-nb and the other wavelength components (noise light components) are reflected by all of the BPFs and outputted from the port 2-nc. When the WDM signal light including wavelengths except for .lambda.1, .lambda.2 . . . .lambda.n is inputted into the port 2-nc, the component of the wavelength .lambda.n (noise light component) is outputted from the port 2-1d and the other wavelength components are outputted from the port 2-1a. And, the optical coupler 6 monitors the output light of the BPF 1 to perceive the levels of the respective wavelength components in the WDM signal light.

The opening is watertightly closed by a watertight structure including an annular bead formed in the housing and a packing provided to the closure. An electronic view finder is watertightly isolated in a space defined between a partition wall, arranged within the housing, and the housing. A cover is provided between the closure and an electronic equipment, such as a video deck, disposed within the housing, and a packing is arranged between the housing and the cover so that the space surrounded by the cover and the housing is held watertightly. Alternatively, the gap between a portion of a video deck disposed in the housing and a housing is watertightly sealed, the portion of the video deck projecting from the housing the opening. A water absorbent or a water sensor is disposed in a recess formed in the housing.

    摘要： 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. Even if the recording trigger switch is manipulated, an AND gate turns off in response to an output of the state detection circuit and inhibits image writing into the semiconductor memory.

    摘要： An electric camera includes an imaging device which converts an optical image focused thereon into an electric signal, a first memory which stores the electric signal, a compressor which generates compressed image data from the electric signal stored in the first memory, a second memory which stores the compressed image data, a decompressor which generates an electric signal from the compressed image data stored in the second memory, a progressive selection switch which directs the progress of reproducing an image on a monitor, a connector which is able to connect the camera with an external device, and a control circuit. The control circuit controls writing operations of the second memory according to an external data access from the external device and reading operations of the second memory according to an internal data access which occurred by an operation of the progressive selection switch. Further, the control circuit inhibits writing operations of the second memory according to an external data access independent of an external access direction from the external access device when the internal data is being executed.

    摘要： 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. Since the video camera unit is composed of minimally necessary parts and is rotatably pivoted on an edge of the housing, a rotatable joining portion of the video camera unit with the housing can be reduced in size and weight. This structure also allows the user to adjust the angle of the video camera unit only with the thumb and index finger.
