摘要： PURPOSE:To minimize the number of component parts and to miniaturize a color picture input device by using an electrochromism element to a color separating filter with variation of the voltage impressed to said electrochromism element and therefore changing the spectrum of the transmitted light. CONSTITUTION:When color information R, G and B are read in the form of electric signals, an original 2 is irradiated a white light source 1. Then the reflected light of the original 2 is transmitted through a color separating filter 3 using an electrochromism element. The voltage impressed to the electrochromism element is varied in three steps. As a result, the transmitted beams 8 of R, G and B are obtained and a photodetecting sensor 4 detects the spectrum intensity of these beams 8. This spectrum intensity is converted into electric signals.

摘要： PURPOSE: To simplify the structure of a color information reading part by changing a voltage applied to a double refraction liquid crystal cell to separate selectively and take out spectrums of the transmitted light corresponding to color information R, G, and B.
CONSTITUTION: A double refraction liquid crystal cell 10 is used as a color separating filter 4. For the purpose of reading color information R, G, and B as electric signals, an original 2 is irradiated with a white light source 1, and its reflected light 7 is separated into R, G, and B by the color separating filter 4 using the double refraction liquid crystal cell 10 and is detected as the intensity of a transmitted light 8 by a light receiving sensor 5 and is converted to an electric signal. Since only the voltage applied to the double refraction liquid crystal cell 10 is controlled to facilitate separation into monochromic lights R, G, and B, the while light source 1 can be used as the light source, and only one light receiving sensor 5 is required, and the device structure is simplified and is made small-sized.

摘要： PURPOSE:To improve expressing performance for half-tone and to perform half- tone recording with fidelity by controlling the diameter of a laser beam spot on the surface of a photosensitive body to record in responding to the density with which the recording is performed. CONSTITUTION:A filter 13 having an increasing transmitance rate toward the center part is installed between a laser diode 11 and a rotary polygon mirror 14, and the intensity of a laser beam outputted by the laser diode 11 is converted into a beam having the distribution corresponding to the density signal of recording information.

Only a beam with light intensity larger than a specific slice level Lth operates effectively on the photosensitive body 16, so beam spots with different diameters corresponding to the light intensity distribution, e.g. B1-B3 are formed.

摘要： PURPOSE:To maintain the comparatively high picture quality despite reduction of number of gradations and to attain transmission of moving pictures with a narrow band, by using a receiver having a display screen with reduction of its physical size. CONSTITUTION:For a transmission side device 10, the gradation information is reduced from the picture information fed through a TV camera 11 by a gradation information reducing part 12. The part 12 suppresses the gradation corresponding to the light intensity supplied through the camera 11 by 1-3 bits for each picture element. Then the picture informaton is coded by a coder 13 and stored to a frame memory 14. The contents of the memory 14 are transmitted to a reception side device 16 via transmission line 15 of a narrow band. The device 16 decodes the received picture information stored in a frame memory 17 by a decoder 18 and therefore restores the moving pictures. These restored pictures are delivered and displayed at a display part 19. In this example, the deterioration of mental satisfaction due to reduction of the gradation information can be compensated by reducing the physical size of the screen of a display part 19 of the device 16.
