摘要： PROBLEM TO BE SOLVED: To provide technique related to a dynamic image advertisement medium having a form in which various color pictures and graphic characters are displayed. SOLUTION: The elements of the plate are planar reflection mirrors (reflection prisms) having their apex angles to be a right angle or a semi-right angle or curved surface reflection mirrors (semi-reflection prisms). A color film 13 is inserted between the elements. At both sides of the front tip sections of the film 13, color information is provided. When the film 13, in which its drive is made invisible, is moved between two mirrors, the color pictures of the both sides of the front tip sections display a picture on a plane surface or a semi- plane surface through reflection surfaces 12 of the two reflection mirrors, When the pictures of the elements are arranged on a single flat surface, they become a perfect single graphic. When the drive makes regular reciprocating movement in accordance with time, the picture constitutes a specific dynamic image.

摘要： PURPOSE:To lighten a color image by mixing a beam of 568.2nm and a beam of 647.1nm emitted from Kr laser or Ar-Kr mixed gas laser and using the resulting laser light as the red light of an image. CONSTITUTION:A beam of 568.2nm (yellow light) and a beam of 647.1nm (red light) emitted from Kr laser or Ar-Kr mixed gas laser are mixed to obtain laser light corresponding to single-color light of about 612nm. When this laser light is used as the red light of an image, lightness is increased by laser light of 568.2nm as compared with the conventional case using only red laser light of 647.1nm and the lightness of the entire image is increased. The consumption of electric power is reduced if it is not necessary to increase the lightness of the entire image. A laser image display is reduced in size as compared with a display using dye laser.

摘要： PURPOSE:To automatically change the direction of a camera aiming at the motion of a transmitting or a receiving user, and to take the picture of the said user from a suitable angle always by detecting the position of the said use, and controlling the direction of the camera according to the detected signal of the position. CONSTITUTION:A detecting device 2A is constituted with a transmitter 5 consisting of an LED 53 to emit an infrared ray, and a receiver 6 consisting of two photodiodes 62 to receive the infrared ray, and a control device 2B is constituted with a comparator 7 to compare the respective intensities of the infrared ray, caught by the two photodiodes 62, and a switching circuit 9 to switch the +, - of an power source 8 according to the output of the comparator 7, and a motor 10, the direction of the rotation of which is controlled by the switching of the switching circuit 9. Then, the detecting device 2A detects the position fo the transmitting or the receiving user, and the control device 2B controls the direction of the camera 1 according to the detected position of the said user, and takes the picture of the user at a suitable direction.

摘要： PURPOSE: To prevent scanning performance from being spoiled even when a set is compacted by spreading a scanned laser light beam horizontally and then projecting it on a screen.
CONSTITUTION: The luminance modulation signal of an image signal is sent to an optical modulator 4 from an image signal source 2 through a video amplifier 3, and the luminance of a laser light beam emitted by a light source 1 is modulated individually with the video signal. Three modulated laser light beams of red, green, and blue are put into one laser light beam by a dichroic mirror 5 to illuminate a deflecting device 6. A vertical and a horizontal synchronizing signal are sent to the deflecting device 6 from the video signal source 2 through a horizontal and vertical driving device 7. The deflecting device 6 consists of a horizontal scanner 6b and a vertical scanner 6a which each consist of a rotary polygon mirror to scan the laser light. The scanned laser light beam is expanded horizontally by a semicylindrical convex mirror 8 and projected on the screen 9.
