Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to an electronic blackboard device, and more particularly to an electronic blackboard device that records and reproduces image and audio data.
[0002]
[Prior art]
As shown in FIG. 2, the conventional electronic blackboard apparatus receives image data 1 from a host system and displays meeting materials on the display means 11. The display surface of the display means 11 is provided with a touch panel 12. The handwritten data input by handwriting is held in the handwriting memory 7 and is combined with the image data 1 input from the image input means 3 by the combining means 6 and displayed on the display means 11, and the audio 2 during the meeting is input by voice Input by means 4 and stored in audio memory 109.
[0003]
Further, the control means 108 controls to read out the image data 1 and the sound data from the display memory 10 and the sound memory 109 respectively, and the sound data related to the image data 1 displayed on the display means 11 is read out from the sound memory 109. And output by the audio output means 13.
[0004]
[Problems to be solved by the invention]
As described above, since the conventional electronic blackboard device does not have a temporal association between the audio data discussed during the meeting and the image data added during the meeting for one material, the progress of the meeting is detailed. There was a problem that could not be reproduced.
[0005]
SUMMARY OF THE INVENTION Accordingly, an object of the present invention is to provide an electronic blackboard device that stores image data added to a document and audio data during a meeting in association with time.
[0006]
[Means for Solving the Problems]
In order to solve the above-described problems, an electronic blackboard apparatus according to the present invention is input from an image input means for inputting image data sent from a host system, a handwriting input means for inputting handwritten data, and the handwriting input means. A handwriting memory for storing the handwritten data, a combining means for combining the handwritten data stored in the handwriting memory with the image data and sending display data, and a display for displaying the display data sent from the combining means Means, a display memory for storing display data displayed on the display means, a voice input means for inputting the voice of the user of the display data, and a discrimination code is added to the voice input by the voice input means. Encoding means for transmitting audio data, an audio memory for storing audio data transmitted from the encoding means, and an audio memory stored in the audio memory Voice output means for outputting voice data; and when the handwritten data is not input for a predetermined period or longer, the display memory is controlled to store the display data, and a discrimination code is added to the voice to add the discrimination code And control means for controlling the display means and the sound memory so as to store them, and controlling the display data and the sound data to be reproduced by the display means and the sound output means in a time-related manner by the discrimination code. It is characterized by that.
[0007]
DETAILED DESCRIPTION OF THE INVENTION
Next, an electronic blackboard apparatus according to an embodiment of the present invention will be described with reference to the drawings.
[0008]
FIG. 1 is a block diagram of the electronic blackboard device according to the first embodiment of the present invention.
[0009]
As shown in FIG. 1, an electronic blackboard device according to an embodiment of the present invention includes an image input unit 3 for inputting image data 1 sent from a host system, and a touch panel 12 of a handwriting input unit for inputting handwritten data. The handwriting memory 7 for storing the handwritten data input from the touch panel 12, the combining means 6 for combining the handwritten data stored in the handwriting memory 7 and the image data 1 and sending the display data, and the combining means Display means 11 for displaying the display data sent from 6, display memory 10 for storing the display data displayed on the display means 11, voice input means 4 for inputting the voice 2 of the user of the display data, A coding means 5 for adding a discrimination code to the voice 2 inputted by the voice input means 4 and sending voice data, and a sound sent from the coding means 5 The voice memory 9 for storing data, the voice output means 13 for outputting the voice data stored in the voice memory 9, and the display memory 10 for storing the display data when handwritten data is not inputted for a predetermined period or more. The control unit 5 controls the encoding unit 5 and the audio memory 9 to add the discrimination code to the audio 2 and store it in the audio memory 9, and the display unit 11 correlates the display data and the audio data in time with the discrimination code. And the control means 8 for controlling the reproduction by the audio output means 13.
[0010]
Next, the operation of the electronic blackboard device according to the embodiment of the present invention will be described with reference to the drawings.
[0011]
The operation of the electronic blackboard apparatus according to the embodiment of the present invention is controlled when image data 1 sent from the host system is input to the image input means 3 and displayed on the display means 11 as shown in FIG. The storage of voice data is started in the voice memory 9 under the control of the means 8, and a series of handwriting processes are completed when there is no input for a predetermined time, for example, one minute after the handwriting data from the touch panel 12 is started to be input to the handwriting memory 7 The control means 8 determines that the display data is output, the display data output from the synthesizing means 6 is stored in the display memory 10, the storage operation is stopped until the next handwritten data is input to the handwritten memory 7, and then the handwritten data is stored. After the input to the handwriting memory 7, the process of storing the display data output from the synthesizing means 6 when it is not input again for one minute is repeated.
[0012]
Further, the storage operation of the image data 1 at the beginning of the conference stores all the display data output from the synthesizing means 6, and in the case of the second and subsequent image data storage operations, the display data stored last time and the current storage are stored. Only the data of the difference from the display data at the point of time is stored.
[0013]
On the other hand, the audio 2 during the meeting is taken in via the audio input means 4 and a discrimination code is added by the encoding means 5 in synchronization with storing display data in the display memory 10, and this discrimination code is added. When the playback operation is started, the control means 8 controls the display means 10 to read out the initial image data 1 from the display memory 10 and display it on the display means 11, and during the meeting. The audio memory 9 is controlled so as to read out the stored audio data for each discrimination code and output by the audio output means 13.
[0014]
Therefore, the control means 8 reads the display data stored next to the display data currently displayed from the display memory 10, and displays the display data obtained by adding the display data displayed on the display means 11 and the read display data. By displaying on the display means 11 and repeating this operation, an image at the time when the sound being reproduced is stored is displayed on the display means 11.
[0015]
【The invention's effect】
As described above, according to the electronic blackboard device of the present invention, the image data added to the material during the meeting and the audio data during the meeting can be stored in a time-related manner. There is an effect that the added image data and audio data recording the discussion during the conference can be reproduced in association with the progress of the conference.
