ABSTRACT:
BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates to a conference apparatus and a conference system, and more particularly to a conference apparatus and a conference system having a shared board function and an image recording function.
2. Related Background Art
For recording the proceedings of a video conference, there have been utilized the methods of (1) video recording the image and voice of a monitor, (2) storing or printing the information written on a shared board, by an operation of the user, and (3) video recording the image and voice of the counterpart of the conference.
However, the recorded result obtained in such conventional recording methods has only limited value for re-utilization. More specifically, in method (1), in which the content of the conference is stored in the form of video information, it is difficult to utilize the proceedings of the conference for example in a computer by extracting the written information on the board and storing it in a file.
In method (2), in reviewing afterwards the stored written information on the shared board, it is difficult to trace the proceeding of the conference and the discussion at the conference, such as the explanation on the written information, cannot be obtained.
In method (3), it is impossible to exactly comprehend the proceeding of the conference from the reproduced video information, as the written information on the shared board is not available.
Also these methods, even if used in combination, are still inconvenient because the different recording means are not mutually linked. For example, in the combination of methods (2) and (3), it is still difficult to comprehend the proceedings of the conference by reviewing the video information in combination with the written information on the board, because the correlation thereof in time is not available and has to be supplemented by human memory.
SUMMARY OF THE INVENTION
In consideration of the foregoing, an object of the present invention is to enable recording and reproduction of the proceeding of a conference in a form with improved reutilizability.
Another object of the present invention is to provide a conference apparatus and a conference system capable of storing both the data of a shared board and the input image.
Still another object of the present invention is to store the data of a shared board and the input image separately, with mutual correlation in time, thereby improving the value of reutilization of such data and input image at the reproduction thereof.
The foregoing objects can be attained, according to a preferred embodiment of the present invention, by a conference apparatus comprising image memory means for storing image information entered in a conference, in correlation with time information, a shared board having the same image in the present apparatus and in a conference apparatus constituting the counterpart of the conference and adapted to be written in from the present apparatus and from the counterpart apparatus, and shared information memory means for storing the writing information on the shared board in correlation with time information.
Still another object of the present invention is to improve the operability in the reproduction of the data of the shared board and the input image, stored separately.
Still another object of the present invention is to provide a conference apparatus and a conference system with novel functions.
Still other objects of the present invention, and the features thereof, will become fully apparent from the following detailed description, which is to be taken in conjunction with the attached drawings.
