Embodiments of the present invention will be described below in detail with reference to the drawings. FIG. 2 is a configuration diagram of the learning system of the present invention. 1 is a large screen display, 2 is a terminal device with a small display, 3 is a controller for teachers, 4 is a LAN, and 5 is a computer. The controller 3 for teachers may also have the database function of the computer 5.

A case of learning about a historical building of the Asuka era in a class on Japanese history will be described as an example. The teacher operates the control device 3 at hand to access the database of the computer 5, and projects a video relating to Horyuji according to a predetermined story on the large-screen display 1 so as to show a movie. At this time, the presence is enhanced by making full use of a three-dimensional image or a three-dimensional sound device. By staring at the large-screen display 1, the students can enjoy an immersive feeling as if they were actually visiting Horyuji Temple.

Prior to the start of the lesson, one or several students are selected from among the students. The selected student will be the avatar for the pre-determined role of the class for the day. The student acting as the avatar operates the terminal device 2 to freely move around as a avatar in the historical building projected on the large-screen display 1 and relive the behavior of a historical person (role play). ) And deepen learning. In that case, for each student, for example, they are interested in the structure and pattern of the pillars of Horyu-ji, interested in paintings hung on the wall, and wanting to look inside the vase where they are placed. The subject is expected to be different.

That is, the whole story unfolds on the large screen display 1, but the location where it moves around varies depending on the interest and the degree of interest of the student as the avatar, and the end depends on the judgment of the student as the avatar. . By changing the role of avatar, classes can be developed from multiple perspectives.

In the course of further lessons, it is expected that, for example, learning about lifestyles and Prince Shotoku at the time Horyuji was built will be developed. desirable. These related data may be presented by the teacher or, for example, a database of an electronic library may be searched to collect information.

The contents and progress of the lecture as described above
Even if you start a lecture using the same teaching materials, it naturally depends on the interests and understanding of the students at that time. Therefore, during or at the end of the lecture, the independent viewpoint image generated by moving around as an avatar and related data searched or supplemented in relation to the independent viewpoint image are stored in the recording device provided in the control device 3. Record and accumulate as appropriate.

Note that the generated independent viewpoint image is

When the above-mentioned processing and editing means is provided in the terminal device 2 with a small display for students to enable processing and editing by the student, the processing and editing results are transmitted to the control device 3 for teachers and the The information is shared on the screen display 1 so that the teacher can check the processing and editing results.

In this case, it is important to know whether the processing of the original image data is permitted in terms of copyright or whether only the use is permitted. Therefore, the copyright data relating to the use of the recorded and stored image, including duplication, public transmission, performance, screening, distribution, lending, and adaptation, is displayed on a display device provided in the controller 3 for teachers. By checking the displayed copyright data, the teacher can judge whether the image can be freely processed and edited. In some cases, the copyright data may be displayed on the terminal device 2 with the small display.

FIG. 3 shows a display example of copyright information (data). The teacher's control device 3 includes, as the copyright data, the content name of the digital video to be copyright-managed, the name of the content copyright owner (there may be a plurality of people), the content usage conditions (period, place, usage mode, etc. ), And holds and manages information such as content owner names. Information such as an e-mail address and a URL (Uniform Resource Locator) may be held as the content copyright owner name and content owner name. When there is a display request from the teacher, the controller 3 for teacher displays the information on the display. Also, when there is a request for processing / editing an image, which does not satisfy the usage conditions, the copyright data is automatically displayed.

If the data cannot be edited or edited without permission, the copyright holder is inquired from the control device 3 using a communication line such as the Internet from the control device 3 to request that the use is not permitted. Then, an answer from the copyright holder regarding use is displayed on a display device provided in the control device 3. Based on the answer, the teacher performs additional registration of the copyright data on use in accordance with the content of the above-mentioned recorded and stored image, public transmission, performance, screening, distribution, lending, and adaptation. When the registration is made, a usage fee corresponding to the usage mode is charged, and the teacher or the accountant at the educational facility pays a predetermined fee.

Further, when processing the recorded and stored image, the specific terminal identification number of the control device 3 used, the name of the processing editor, and the copyright data may be attached to the video of the processing and editing result. desirable. As this attachment method, it is possible to prevent falsification of the embedded data and prohibit its misuse by embedding it in video data using a digital watermarking technique described later.

As described above, since the use, processing, and editing of digital image data are performed in accordance with the copyright rules, copyright problems can be avoided.
