Abstract

PROBLEM TO BE SOLVED: To accurately make arrangements while watching a color picture in real time by connecting a color still picture adapter connected to a personal computer between a hand set and a telephone main body. SOLUTION: The color still picture adapter 3 is connected to between the hand set 1 and the telephone main body by means of a modular jack and from the adapter 3, a serial connector and a parallel connector are connected to the serial connector and the parallel connector of the personal computer. A personal computer color picture 10 is turned to an electric signal through a serial port and parallel port 8. The electric signal entering the adapter 3 is generated to be a color picture demodulation signal 4 and continually converted into a scanning line 5 for receiving TV. The signal converted into be the scanning line 5 is additionally low-frequency-converted 6 and transmitted through a general telephone line. At the time of speaking while watching a received picture, speaking from the hand set 1 is made possible by a switch 7 so as to selectively use corresponding to usage.

Description

Detailed Description of the Invention

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a device which can easily analyze and make a meeting by sending industrial and general consumer information as color still image data to a remote place through a general telephone line. is there.

[Prior Art] Conventionally, a FAX, a TV phone or a personal computer communication was used to transmit a character or an image to a remote place. FAX uses paper media, but it is monochrome, so accurate information could not be transmitted in industries that require color. For videophones, it is necessary to invest in equipment for communication-only telephone lines and auxiliary equipment. Also, personal computer communication can send characters and color images, but it was mostly machine-to-machine communication with a host or server. For that reason,
It was extremely difficult for a person who was not familiar with a personal computer to talk with the other person in real time and discuss with color presentation materials. Generally, personal computer communication uses a modem, but this is mainly a data communication device, and it was difficult to communicate with the other party through a call and an image.

[Problems to be Solved by the Invention] Therefore, it takes a lot of time to communicate with a remote place because the drawings are sent to the other party in advance and the telephone is exchanged at a later date. Even when using a monochrome FAX or telephone, it was not possible to convey accurate information to the other party, which was a source of error.
The present invention was invented in order to meet the strong demand of the user whether an accurate meeting can be performed while viewing a color image in real time.

[Means for Solving the Problems] As a result of pondering how to solve the above-mentioned problems, the inventor found that a commercially available telephone set was used between the handset 1 and the telephone body 2. The color still image adapter 3 was connected with a modular jack, and the serial connector and the parallel connector from the color still image adapter 3 were connected to the serial connector and the parallel connector of the personal computer 9.

Further, the electric signal that has entered the color still image adapter 3 is generated into the color image demodulated signal 4 and then T
The switching SW7 is used to repeat the conversation and the color still image converted into the V image receiving scanning line 5, further converted into the low frequency frequency 6 and transmitted through the general telephone line.

[Operation] The present invention can be used in general household or business telephones on the market, and the serial connector or parallel connector of the color still image adapter 3 can be changed by connecting between the handset and the telephone body. It connects to a connector or parallel connector, and no special work is required. After connecting, you can have a real-time conversation and color image communication with the other party. The sent image can be stored in an auxiliary storage device such as a hard disk of the personal computer 9 as in general personal computer communication. Further, since the color image demodulation signal 4 is an audio signal, a special auxiliary storage device is not required and recording / storing / reproduction can be performed with a cassette tape or the like of an answering machine.

[Embodiment] The embodiment shown in the drawings will be described in more detail below. Fig. 1 On the telephone, a color still image adapter 3 is connected between the handset 1 and the telephone body 2 by a modular jack, and from the color still image adapter 3, the serial connector or parallel connector is connected to the serial connector or parallel connector of the personal computer 9. . Any jack that is commercially available and easily compatible, such as a parallel connector or a connector that can be used for connection, can be substituted. Further, the same effect can be obtained if the communication line uses not only a telephone but also a general communication device, a disaster prevention radio, a business radio, a mobile phone, or the like by radio. Color still image adapter 3 in Figure 2
As a power source of, a minute current from a serial port or a parallel port of the personal computer 9 can be used. PC color image 10
Is converted into an electric signal through a serial port / parallel port 8, and the electric signal that has entered the color still image adapter 3 is generated into a color image demodulation signal 4 and subsequently converted into a TV image receiving scanning line 5. The signal converted to the TV image receiving scanning line 5 is further low-frequency converted 6 and transmitted through a general telephone line. When talking while looking at the received image, it is possible to talk from the handset 1 by the switch SW7, and it can be used properly according to the purpose. Also, switch SW7
Even without it, it is possible to create programs and switch automatically with a microcomputer.

[Advantage of the Invention] According to the invention, in the medical field, a color still image of an affected area is sent to a remote place, data analysis of a specialist, analysis of an X-ray photograph, or a situation of a scene at the time of a great disaster is taken as a countermeasure still image. The real-time data analysis of the sending specialist can protect many human lives from disasters. Alternatively, it is possible to send the color, design, etc. in the business for general consumers to a remote place through a general telephone line and have an instant meeting to achieve the result. It can be used with ordinary household and business phones on the market, and anyone can easily connect to it. It is not always necessary to use a special ISDN, INS64 or the like like high speed modem communication. Also, no special construction is required. The price is about half the price of general commercial modems. Operation is much easier than PC communication, and anyone can master it. Even when the other party is away, you can send color still images as well as voice requirements to your answering machine. By using color images to delicately display details and express expressions in detail, it is possible to have a clear conversation. By utilizing the advantage of bidirectional communication, it can be used on the extension communication line within the company. Furthermore, it can also be used as a home-based tool that enables work at home.
