Description

Description: TECHNICAL FIELD The present invention relates to a data processing method.

[Prior Art] Conventionally, a data processing device that performs common display and common work with a partner communication terminal has been devised.

[Problems to be Solved by the Invention] However, in the conventional device, even though the user can write his / her own memo, when reflecting the written memo on the common screen later, only a part of the memo is displayed on the common screen. There is a problem that even the part of the memo that the user does not want to be known to is reflected on the common screen.

An object of the present invention is to provide a data processing method which is easy to use in consideration of the above-mentioned drawbacks.

Means for Solving the Problems According to the present invention, a common display in which the content displayed on the display unit of the own terminal is the same as the content displayed on the display unit of another communication terminal is displayed on the display unit of the own terminal. Common display stage,
An additional writing step of additionally writing predetermined drawing information on the common display displayed on the display unit of the own terminal, and not displaying the predetermined drawing information on other terminals; and In the instruction step, the user indicates a predetermined portion, and the predetermined portion specified by the user,
Transmitting to the other communication terminal in order to reflect and display the same as the common display. A data processing method, wherein the common display is not displayed on the display unit of the communication terminal.

Embodiment FIG. 1 is a block diagram showing a telewriting device according to an embodiment of the present invention.

This telewriting device includes a line control unit 1, a drawing codec unit 2, an audio input / output control unit 3, an audio input / output unit 4,
It has a storage unit 5, an overall control unit 6, an input / output control unit 7, a drawing input unit 8, a control information input unit 9, and a display unit 10, and performs voice and drawing with one or a plurality of telewriting devices. It performs information communication.

The line control unit 1 controls an interface between the telewriting device and the line 11.

The drawing codec 2 is a circuit that encodes and decodes drawing information.

The voice input / output control unit 3 controls input / output of voice information, and includes a voice codec for performing A / D conversion when connected to an ISDN network.

The voice input / output unit 4 inputs and outputs voice information, and corresponds to a handset, a microphone, a speaker, and the like.

The storage unit 5 is a circuit that stores drawing information performing mutual communication and memo information dedicated to the user with an identifier.

The overall control unit 6 is a circuit that controls the entire telewriting device.

The input / output control unit 7 controls input and output of drawing information, control information, and the like.

The drawing input unit 8 is for inputting drawing information, and the control information input unit 9 is for inputting control information.

The display unit 10 displays drawing information, control information, and the like, and forms a common screen based on the drawing information communicated with each other.

The line 11 is an ISDN line, a telephone line, or a dedicated line.

FIG. 2 is a schematic diagram showing a conference system in which such telewriting devices are connected at three points.

Each telewriting device (terminals A, B, C) 20, 21,
22 is connected to the multipoint via the network or the conference controller 30 by the line 11.

FIG. 3 is a flowchart for explaining an operation example when a conference is performed by such a conference system.

First, each of the terminals A, B, and C displays the screen 91 shown in FIG. 4 as a common screen on the respective display units 10 and has a meeting (S1).

Here, the operator of the terminal B needs to add information for his / her memo on the common screen 91 while listening to other explanations. Therefore, the operator of the terminal B first switches the writing mode of drawing to the memo mode (S2). Next, drawing information such as the area 92 shown in FIG. 5 is added as a memo on the screen (S3). The memo added to this area 92 is the terminal B
Is displayed only on the screen of the terminal B, and the storage unit 5 of the terminal B
Is also stored as memo mode writing.

Here, in the area 92 added as this memo, the area 93
Has to be reflected on the common screen. Then, the operator of the terminal B confirms the area 92 added as a memo.
Out of the area 93 is specified on the common screen, and the drawing information of this portion is also transmitted to the other terminals A and C.

At the same time, the content stored in the storage unit 5 of the terminal B is also changed from the memo mode to the drawing information of the area 93 as common screen information (S4).

Also, the portion of the region 92 other than the region 93 is
It remains stored as a memo.

Although only the drawing information has been described in the above embodiment, a more luminous system can be constructed by combining with a still image such as a facsimile or code information such as a word processor or a personal computer.

Also, when adding your own memo to the common screen, instead of adding it unconditionally, send it to everyone in the form of "memo → common information conversion request" and share it when the other party's approval is obtained A method of adding the information as screen information is also possible.

Further, it is possible to temporarily or permanently display the color of the memo so that it can be identified on the screen.

[Effects of the Invention] According to the present invention, predetermined drawing information is additionally written on the common display displayed on the display unit of the own terminal, and the other terminal does not display the predetermined drawing information. The user designates a predetermined portion of the additionally written drawing information, and transmits the information specified by the user to the other communication terminal in order to reflect and display the specified portion as the common display. So that only the parts that the user considers to be open to other terminals can be displayed on other terminals,
There is an effect that the memo portion of the own terminal can be directly reflected on the common screen of the partner terminal without performing the work of copying only the memo portion of the own terminal again on the common screen.
