DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a performance evaluation system for evaluating performances for a large number of people, such as lectures, classes, lectures by celebrities, and performances by celebrities and musicians at educational institutions such as universities and preparatory schools. It is about.

[0002]

2. Description of the Related Art As described above, lectures and classes at educational institutions such as universities and preparatory schools, or lectures by celebrities,
2. Description of the Related Art In performances and performances for a large number of people, such as performances by entertainers and musicians, broadcasting via television or radio, video recording, and the like are frequently performed. Furthermore, a lecture package by a famous university professor, a famous preparatory school teacher, or the like may be relayed and distributed to a remote place by television or video.

[0003]

In any case, a system is constructed mainly by a person who gives a lecture or a performance, and a video of the audience or a sound such as applause or cheer is processed as noise rather than the audience. It was just one way to excite the performance. However, recently,
Demands have arisen to be able to measure the performance of lecturers, performers' lectures, performances, etc. by some means. To this end, methods based on opinions from audiences or questionnaires are used. It is common, but there is a problem that the method of hearing opinions is complicated, the number of samples is limited, the subjectivity of the audience is involved, and it is not possible to judge the quality of lectures and performances by a third party Was.

[0004] It is an object of the present invention to solve the above problems and to provide a system which can objectively judge the result of a lecture or performance by taking into account the reaction of the audience. And

[0005]

The present invention for achieving the above object is as follows. (1) In a performance evaluation system for evaluating the content of a performance performed in front of a large audience, a camera for capturing an image of the audience, and a video pattern preset by incorporating video information from the camera. A performance evaluation system, comprising: a central processing unit for comparing and comparing the comparison result with the performance; (2) In a performance evaluation system for evaluating the contents of a performance performed in front of a large number of audiences, a sound collection microphone for acquiring the sound of the audience, and sound information from the sound collection microphone are taken in and set in advance. A performance evaluation system comprising: a central processing unit that compares the sound pattern with the sound pattern and evaluates the result of the comparison. (3) In a performance evaluation system for evaluating the contents of a performance performed in front of a large number of audiences, a camera that captures images of the audience, a sound collection microphone that acquires the audio of the audience, and video information from the cameras. And a central processing unit which incorporates the audio information from the sound collecting microphone and compares it with a preset video pattern and audio pattern and evaluates the result of the comparison with the central processing unit. Evaluation system. (4) The performance evaluation system according to (1) or (3), wherein the camera is a pan-tilt camera. (5) The performance evaluation system according to (3) or (4), wherein the camera and the sound collection microphone are integrated.

[0006]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, the present invention will be described in detail with reference to the drawings. In Figure 1, speakers, performers, university professors,
A performer 1 such as an entertainer gives a lecture and a performance as usual, while a camera 3 for photographing the facial expression and attitude of the audience 2 and a voice from the audience 2 to an audience 2 such as students and spectators. Is installed.

[0007] The image of the camera 3 shooting the audience 2 is
The image data is transmitted to the image processing apparatus 5 via the network N, where the image processing is performed. That is, from the facial expression of the person constituting the audience 2, the operator recognizes, for example, a state of falling asleep, a state of depression, a private word, whether he / she listens eagerly, and the like. Alternatively, a plurality of types of image patterns, i.e., a dozing pattern, a depression pattern, a private language pattern, a listening pattern, and the like for an individual or a plurality of persons are registered in advance, and the person or the plurality of persons are compared with the obtained image information. Recognize the current listening status of. The camera 3 is not panned and photographed only at a certain point, but is pan-tilt type to photograph the entire audience, so that it is easy to grasp the whole audience.

Further, the sound from the sound collecting microphone 4 is transmitted to the sound processing device 6 via the network N, and the size of applause, cheers, and the level of private language are captured, and the degree of concentration of the audience is determined based on the sound level and spectrum. Is recognized by the operator. Alternatively, a plurality of types of voice patterns are registered in advance, and the listening state of the audience 2 is recognized by comparing the obtained voice information with the obtained voice information.

In practice, if the camera 3 and the microphone 4 are integrated, it is possible to simultaneously obtain video and audio, and to obtain detailed information.

Further, information from the image processing device 5 and the audio processing device 6 is transmitted to the central processing unit CPU, and the central processing unit CPU, for example, transmits a predetermined comparative evaluation pattern, that is, an image processing unit. It counts the number of people falling asleep, the number of people looking down, the number of people lying sideways, the number of people chatting, etc., obtained from the device 8, and furthermore, actions such as writing notes, dozing actions
The performance of the performer is performed by comparing the video information and the audio information, such as the downward motion, the horizontal motion, the chat operation, and the audio vector, with a predetermined number of behavior patterns or by matching the behavior patterns with a predetermined behavior pattern. It is an index to evaluate the performance of Eventually, the performance of the performer can be calculated.

The result of the evaluation may be displayed on the display 7 or output to the storage device 8 such as a disk or the output device 9 such as a printer.

[0012]

According to the first to fifth aspects of the present invention, the situation of a lecture or a performance can be mechanically captured by a video from a camera or a voice from a sound collecting microphone. Therefore, it is possible to obtain an effect that performances, performances, and the like can be performed, and the results can be objectively determined by a third party.
