Abstract

PURPOSE:To make such an expensive tool as a video camera unnecessary and to cut down the cost of a system by providing a buffer memory storing moving picture data as still picture data and an accumulation device accumulating both still picture data transmitted through a transmission system and the still picture data stored in the buffer memory. CONSTITUTION:Moving picture data is inputted to a moving picture input device 300 or to a controller 900 by a transmission device 700. The controller 900 transmits the moving picture data to a graphic display device 350 which displays the moving picture data. If a user wants to retain the moving picture data displayed on the graphic display device 350, he presses the prescribed switch of an operational input device 850. Then a picture data request signal and the displayed moving pictures of one screen are transmitted to the graphic display device 350 from the controller 900 and to the buffer memory 360, respectively, and both of them are converted in the same format as that of the still picture data and stored. Thus image data converted into still picture data is transmitted to the accumulation device 600 and accumulated in it through the buffer memory 360, the graphic display device 350 and the controller 900.

DETAILED DESCRIPTION OF THE INVENTION [Technical Field of the Invention] The present invention relates to an electronic conference system for conducting conferences between remote points, and particularly to an electronic conference system that converts video data into still image data and stores the same.

[Technical Background of the Invention] As this electronic conference system, for example, the one shown in FIG. 2 can be considered. As shown in the figure, this electronic conference system includes a microphone 1, a speaker 2, a television camera 3 that displays an image of the conference room, a television camera 4 that displays a manuscript,
A trembling monitor 5, a facsimile device 6, a hard copy device 7 as a printer, the microphone 1 and the speaker 2
an audio unit 8 for encoding and decoding audio signals; an image unit 9 for encoding and decoding image signals; a control unit 10 for controlling the image units; and an operation unit 1-11 for inputting instructions for the control unit 9. , a transmission unit 12 that transmits and receives audio signals and image signals.

[Problems with the Background Art] However, in such an electronic conference system, an expensive +a material such as a video camera is required separately in order to retain the video data of the conference room displayed by the television camera 3. Therefore, there was a problem that the price of the system became high.

[Object of the Invention] The present invention has been made to solve these conventional problems, and an object of the present invention is to provide an electronic conference system that can store video data.

[Summary of the Invention] In order to achieve the above-mentioned object, the present invention provides an input system for inputting drawing data, still image data, moving image data, and audible sound data, and an input system for inputting drawing data, still image data, moving image data, and audible sound data. A conference unit system consisting of an output system that outputs data, a transmission system that controls the transmission of these data between remote points, and a control system that controls the input system, output system, and transmission system is connected to a line. In an electronic conference system in which a plurality of devices are connected via a buffer memory that stores moving image data displayed on a graphic display device that displays moving image data as still image data, and still image data transmitted via a transmission system and the A storage device for accumulating still image data stored in a buffer memory is installed in the conference unit system1d.

[Embodiments of the Invention] Hereinafter, embodiments of the present invention will be described in detail based on the drawings.

FIG. 1 is a block diagram showing a conference unit system as an embodiment of the electronic conference system of the present invention.

The control device 900 is connected to drawing, still image, moving image, and audio input devices, and to the control device 900 is connected to soft copy, hard copy, and audio output devices. Signals from these input devices and signals to output devices are subjected to processing such as selection and multiplexing according to several control information signals, and are then transmitted.

The input devices include a plurality of drawing input devices 100 for inputting handwritten characters and figures, a picture input device 200 for inputting documents before or during the meeting, and a background of conference participants and the conference hall. A video input device 300 for inputting images, and an audio input device 400 for inputting audio.
is connected.

In addition, the output devices include a plurality of flat display devices 150 and a graphic display device (1) 160 that display input information of the own terminal and transmitted drawing type and still image type, and a graphic display device (1) 1
A hard copy device 250 for making a copy of 60, a graphic display device (2>350) for displaying the own terminal and transmitted video input information, and an audio output device 450 for outputting transmitted audio input information are connected. has been done.

The graphic display device (2) 350 includes a graphic display device (2).
) 350 is provided as a buffer 7 memory 360 for storing one screen worth of video data as a still image.

In addition, these input/output information are recorded and read by the storage bag @600. The transmission device 700 is connected to two other remote conference unit systems.

The above input/output information is transmitted through signals from devices such as an operation input device 850, a state detection device 800 that detects whether conference attendees are sitting or leaving their seats, and a speaker identification device 510 that determines the speaker based on the voices of the conversation participants. The tip is controlled.

Next, the operation of this embodiment will be explained.

Video data such as images of conference participants and the background of the conference hall are inputted by the video input device 300 or inputted to the control device 900 by the transmission device 700. Control device 9
00 sends this video data to the graphic display device (2>350, and the video data is displayed on the graphic display device (2>350).Here, the video data displayed on the graphic display Gi@(2) 350 is If saved, the operation input device 8
When a predetermined switch 50 is pressed, an image data request signal is transmitted from the control device 900 to the graphic display device (2>350), and data for one screen of the video being displayed is transferred to the buffer memory 3.
60, where it is converted into the same format as still image data and stored. The image data converted into still image data in this way is stored in the buffer memory 360 and the graphic display device 35.
0 is sent to the storage device 600 via the control device 900 and stored there.

In this way, the moving image data being displayed on the graphic display device (2>350) is converted into still image data and stored in the storage device 600.

Therefore, in this embodiment, since video data can be stored, there are advantages such as the ability to use the stored video data as meeting minutes.

[Effects of the Invention] As explained above, according to the present invention, it is possible to convert video data into still image data and store it without the need for expensive equipment such as a video camera, thereby reducing the cost of the system. It can be done cheaply.
