    • PURPOSE:To obtain the picture reproduction device by which a high definition picture is reproduced at a very fast speed by converting an optical signal into a picture signal directly visible. CONSTITUTION:The device is provided with an optical fiber 101 for picture optical signal transmission, a wavelength conversion section 102 applying wavelength conversion to the picture optical signal into a visual light signal, and a sweep section 103 scanning (sweeping) the visual light signal subject to wavelength conversion and displaying a visual picture onto a screen 104 or the like. The wavelength conversion section 102 receives an input signal light and outputs a visual light at a specific wavelength of the input signal light and the sweep section 103 displays the picture on the screen 104 by scanning the visual light in 2-dimension in left/right/upper/lower directions in matching the timing of the signal light. A crystal or an amorphous material formed by doping rare-earth ions is used for the wavelength conversion section 102.

    • PURPOSE:To realize multicolor phosphorescence through simple constitution by forming a phosphor screen of phosphor particles having an absorbing characteristic to absorb the light of wavelength shorter than the wavelength of ecitation light. CONSTITUTION:The phosphor particles 11 are fixed to each other by the binder of transparent or semitransparent resin 12. The phosphor particle 11 is constituted as a globular phosphor particle in which the green and the red long wavelength pass filter layers F1 and F2 of the absorbing characteristics of prescribed wavelengthes are arranged in this order from the inside to the outside between phosphorescent layers. The green long wavelength pass filter layer F1 is arranged between a blue color phosphorescent layer B and a green color phosphorescent layer G, and has the absorbing characteristic to transmit the light of the wavelegth longer than the wavelength of the excitation light lambdaG, and in addition, absorb the light of the wavelength shorter than the wavelength of the excitation light. When the screen is irradiated by plural excitation lights of the wavelengthes corresponding to each phosphorescent layer by mixing their intensities by proper ration, an optional phosphorescent color due to the mixing of a red, a green and a blue colors can be obtained. Thus, the multicolor phosphorescece can be realized through the simple constitution.

    • PURPOSE:To miniaturize the display device and to obtain high resolution by constituting the display device of a color image display device for one horizontal scanning(HS) line provided with three primary colors emitting means arranged in parallel with one HS line section and an optical system means for deflecting image light for one scanning line projected from the display device in the vertical direction. CONSTITUTION:The display device is constituted of a cathod ray tube (CRT) 1 provided with three primary colors emitting means 14B, 14R, 14G and three electron gans 4B, 4R, 4G making pairs with the means 14B, 14R, 14G, a horizontally deflecting coil 2, the optical system 16 for deflecting image light for one HS line in the vertical direction synchronously with a vertically synchronizing signal included in an image signal, and a driving device 17 for driving the system 16. Preferably, image signal amplifiers 10G, 10R, 10B for supplying three primary color image signals t othree glids 82G, 82R, 82B corresponding to the emitting means 14B, 14R, 14G are added. Cathod rays projected from the gans 4B, 4R, 4G selectively emit the means 14B, 14R, 14G and the image light is deflected in the vertial diection by the optical system 16 to constitute an image. Consequently, the display device can be miniaturized and high resolution can be attained.

    • PURPOSE:To make both positions and glances coincident and to enable interaction by detecting the image of a called party in a received picture and moving the detected image to the central part of a screen on a picture display device. CONSTITUTION:A picture recognizing device 14 monitors original picture information stored in a picture memory 13 and detects a part corresponding to the image of the called party. As a picture detecting method in this picture recognizing device 14, the image of the called party is detected by the method of moving part detection, for example. A picture processor 15 executes move processing to the picture data in the part of the image detected by the picture recognizing device 14 so that the data can be positioned in the center of the screen on the picture memory 13. Accordingly, even when the called part is positioned in a place deviated from the front part of a picture display device 17, an image 19 of the called party 19 is projected in the central part of a screen 18 on the picture display device 17. Thus, the both glances can be made coincident.

    • A red image light signal emitting array, a green image light signal emitting array and a blue image light signal emitting array are driven by separate drivers in accordance with one-line image data at a time. The light signals emitted from the arrays are processed by a light signal combining lens and then are incident to a scanning mirror. The scanning mirror vibrates within a specified range of scan angles at a specified frequency, and while the scanning mirror reciprocates once, one frame of two-dimensional image is formed on a projection surface. The scan angle of the scanning mirror is detected by a detector, and the detector sends a detection signal to a timing signal generating circuit. The timing signal generating circuit is stored with values specified for the respective drivers, and when the detector detects that the scan angle becomes one of the values, the timing signal generating circuit sends a timing signal to the corresponding driver.
