Title: Method and apparatus of narrow band dynamic picture communication
Inventor: SUZUKI HAJIME
IPC: H04N7/00
Filed: 1983-11-18
Abstract: PURPOSE:To attain a dynamic picture communication service using a narrow band transmission line by decreasing the number of picture elements of a dynamic picture by one digit and also decreasing the physical size of pattern in the order of two digits to increase the physical picture element density of the pattern. CONSTITUTION:A dynamic picture fetched from a dynamic picture input section 6 is stored temporarily to a frame memory 7. Since the number of picture elements is decreased in the order of one digit as 10<4> as shown in Fig. and the information for <=100X100 picture element number's share has only to be inputted and stored to the frame memory, a small-sized solid-state sensor such as CCD, MOS is used as the input section. Then the information of each frame is compressed by a compressor 8 such as block coding or inter-frame differential coding, the information is transmitted via a narrow band transmission line 9 and after the information is decoded by a decoder 10, the information is stored temporarily to a frame memory 11 of the output side and outputted to a display section 12. The display section has only to display <=100X100 picture element number's share, it is realized by using a small sized display device such as liquid crystal panel, beam index type small sized CRT or the like decreased for the size in the order of two digits.

SOLUTION: This modulator to apply modulation to the surface waves is constituted by using an electro-optical medium in part or the entire part of the dielectric substance of the two-dimensional optical waveguide 18 for guiding the surface waves propagating in the spacing between the negative dielectric substances 11 and 12 by confining the surface waves into the region of a high refractive index in the same manner as in the conventional optical waveguide in a transverse direction. The electro-optical medium of the refractive index changed by impressed electric fields is used for part (core part 13 or clad part 14) or the entire part of the dielectric thin film. A driving voltage source 17 is connected to the negative dielectric substances 11, 12 which are the metallic parts and such dielectric substances are used as the electrodes for impressing the modulation voltage.  A refractive index change is induced in the electro-optical medium by applying the modulation voltage on the electrodes, by which the application of the phase modulation on the surface waves is made possible.
