Title: Data signal processing method and its device
Inventor: KOBAYASHI MITSUSHIGE
IPC: G06E1/00
Filed: 1997-03-21
Abstract: PROBLEM TO BE SOLVED: To directly process data based on color and luminous intensity by adding optical date with an individual meaning corresponding to color and luminous intensity and transmitting and receiving an optical data string given a meaning. SOLUTION: Optical data read from a tone optical memory 23 is sent to a data processing part 28 through a D/L conversion part 22. In this case, actual tone light is generated by a tone light generator 24 and optical data read here is sent to another computer system through a signal port 32 and an ISDN line as it is. The individual meaning is added to optical data corresponding to color and luminous intensity to transmit and receive the optical data string given a meaning. It is desirable that a color sensor 26 does not carry out the tone recognition of one optical point but arranges recognizing sensors by dividing into several areas, e.g. to allow each sensor to independently load tone data signal on a fiber cable line. Of course, the number of divided areas of the optical point are desirably as close as possible to the number of actual picture elements.
