Abstract

PROBLEM TO BE SOLVED: To provide a video telephone conference system by which the name of the current speaker is recognized by compositing the name of a speaker and the image of the entire conference room and transmitting the composite image. SOLUTION: Display means 21, 22 to 2n display preset numbers and names. In the case that voice data from one or some of microphones 11, 12 to 1n are outputted, the voice data are quantized respectively by A/D converters 41, 42 to 4n, the outputs of the A/D converters are compared with a prescribed output level 6 at comparators 51, 52 to 5n. When the output of the A/D converter is higher than the prescribed output 6, the comparator provides a comparison output of a positive level, and then an output means 7 outputs the number and the name. Then a composition means 8 composites the number and the name with image data of the entire conference room received by the camera 3 at the composition means 8 and a modem 9 sends the composited data with audio data.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a video conference device, and more particularly, to a video conference device provided with display means for specifying a speaker.

[0002]

2. Description of the Related Art As shown in FIG. 2, a conventional video-telephone conferencing apparatus uses a camera which outputs voices input from a plurality of microphones 11, 21 to 1n to output means 107 and captures an image of a conference room. 3 is synthesized by the synthesizing means 108, and since the modem 9 transmits the image data via the telephone line, it is necessary to analogize who is speaking in the transmitted image of the entire conference room.

[0003]

Therefore, in the conventional video telephone conference apparatus, the current speaker is estimated from a plurality of conference attendees from the conference state transmitted from the other party and displayed on the television screen. If it's difficult to guess the current speaker on the TV screen sent by the other party,
It was necessary to confirm the current speaker's name again, which hindered the smooth operation of the conference.

SUMMARY OF THE INVENTION It is an object of the present invention to provide a video-telephone conference apparatus provided with a means for synthesizing the names of conference participants with an image of the entire conference room and transmitting the synthesized image.

[0005]

In order to solve the above-mentioned problems, a videophone conference apparatus according to the present invention comprises a plurality of microphones for receiving input voices and outputting voice data; A plurality of display means for respectively displaying preset number data and user name data corresponding to the microphone; a plurality of A / D converters for quantizing each audio data output from the plurality of microphones; A plurality of comparators for comparing an output level of each audio data quantized by the plurality of A / D converters with a predetermined output level; and a plurality of comparators for comparing the audio data compared with the predetermined output level by the plurality of comparators. Output means for outputting number data and name data; a camera for capturing image data of the entire conference room in which the plurality of microphones are set; Synthesizing means for synthesizing the image data of the entire conference room, the number data, and the name data, and transmitting the image data of the entire conference room, the number data, and the name data synthesized by the synthesizing means; And a modem for transmitting data.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Next, a video conference device according to an embodiment of the present invention will be described with reference to the drawings.

FIG. 1 is a block diagram of a video conference call apparatus according to an embodiment of the present invention.

As shown in FIG. 1, a video telephone conference apparatus according to an embodiment of the present invention includes a plurality of microphones 11, 1 for receiving input voices and outputting voice data.
2 to 1n and a plurality of display means 21, 22 to 2n for respectively displaying preset number data and user name data corresponding to the plurality of microphones 11, 12, 1n.
And a plurality of A / D converters 4 for quantizing each of the audio data output from the plurality of microphones 11, 12,.
1, 42, to 4n and the plurality of A / D converters 4
A plurality of comparators 51, 52, to 5n for comparing the output level of each audio data quantized by 1, 42, to 4n with a predetermined output level 6, and the plurality of comparators 5
Output means 7 for outputting the number data and name data of the audio data compared with the predetermined output level 6 at 1, 52, to 5n, and the entire conference room in which the plurality of microphones 11, 12, to 1n are set. Camera 3 for capturing image data
Synthesizing means 8 for synthesizing image data, number data and name data of the entire conference room taken in by the camera 3
And a modem 9 for transmitting image data, number data and name data of the entire conference room synthesized by the synthesizing means 8 and transmitting audio data.

Next, the operation of the video conference device according to one embodiment of the present invention will be described with reference to the drawings.

As shown in FIG. 1, the operation of the video conference apparatus according to one embodiment of the present invention
When 1, 1, 2 to 1n are not used, the comparison results output from the comparators 51, 52, to 5n are all negative, and the output means 8 does not output anything.

On the other hand, one or several microphones 1
When audio data is output from 1, 12,..., 1n, the audio data is quantized by A / D converters 41, 42, 4n, and output to comparators 51, 52,. The predetermined output level 6 is compared with the quantized audio data at 52,..., 5n, and the comparison result is made positive when the level is equal to or higher than the predetermined level, and the reference value is set to enter the microphones 11, 12,. A malfunction due to noise other than the speech is prevented, and the output means 7 sends the number data and the name data of the microphones 11, 12,... The name data and the image data of the entire conference room captured by the camera 3 are combined, and the combined number data, name data, image data and A / D converters 41, 42,. And the audio data from the n modem 9 is transmitted via the telephone line.

The data transmitted from the modem 9 is
Display means 2 for all microphones 11, 12,.
1 to n are displayed on 1, 2, 22 to 2n, and the currently used microphones 11, 12, to 1n among the numbers 1 to n
Is highlighted and the microphone with the same number is searched for from the highlighted number and the other party's conference state to identify the current speaker without fail, and all microphones 11, 12,. 1n, the name of the current speaker can be displayed by uniquely associating the names of the conference participants that would normally be used.

[0013]

As described above, according to the videophone conference apparatus of the present invention, a unique microphone number or the name of a conference participant is displayed by the display means, and the audio data output from the microphone is quantized. Based on the comparison result with the reference value, the currently used microphone number or the name of the conference participant is displayed, the participant on the other side of the conference can reliably identify the current speaker, and the efficiency of the conference This has the effect of achieving
