The storage unit a stores the output video signal (a video signal for displaying a screen like A1).
33.

Next, the video to be stored by the material presentation device a0 is the video to be displayed on the monitor as a "link" before the meeting or when the presenter is changed (both the display video and the bridge video during the material preparation period). This is the video signal of the material to be called. Here, a description will be given assuming that a meeting schedule material (agenda) is a bridge image. In order to store the video of the agenda, the operator of the apparatus places a document to be used as the agenda in the shooting range of the data base a2 (A
2). When the user confirms the image of the agenda displayed on the display screen (B2) and presses a predetermined operation button, the control unit a32 causes the storage unit a33 to store the material video including the agenda as a bridge video.

After the above-mentioned preparations, the operation is shifted to the display of a material image at a meeting or the like. In order to display the video of the material to be displayed on the monitor b0, the operator only has to place the material 32 within the shooting range on the data base a2. As a result, the imaging unit a3
The captured video (A3) including the material 32 output from 0 is transmitted to the monitor b0 via the control unit a32, and the video (B3) including the material is displayed on the display screen b1 of the monitor b0.

On the other hand, the control unit a32 monitors the photographed video signal (A3) input from the imaging unit a30, and stores the live video (A3) currently captured and output by the imaging unit a30 at predetermined time intervals. The image is compared with the video (A1) of the predetermined identification pattern stored in the section a33.

If the comparison shows that the two images (A3 and A1) are different, the live image (A3) input from the imaging unit a30 is output to the monitor b0 via the output terminal a6 as it is, and displayed. (B3).

On the other hand, as a result of comparison, if the same result is obtained continuously for a predetermined number of times, it is determined that no material is currently placed on the data base a2, and the video unit a30 is determined.
Of the agenda previously stored in the storage unit a33 in place of the live video (A4) currently output by the user (A2)
Is output to the monitor b0 via the output terminal a6, and as a result, the captured image of the agenda is displayed on the display screen b1 of the monitor b0 (B4). In addition, while displaying the video of the agenda, the control unit a32 continues the above-described monitoring of the live video signal input from the imaging unit a30, and if the material 31 is newly placed on the data base a2, As a result of the above-described comparison, a newly captured image of the document 32 is displayed on the monitor b0 (B2).

(1) In a meeting or the like using the material presentation device a0, the proceedings of the proceedings before the meeting can be displayed, and the time during which the materials are not presented between the change of the presenters can be effectively used. It has the effect of improving participation awareness. (2) It is possible to eliminate the projection of the upper surface of the data stand a2, which is a scathing scene, and to display a company logo, product introduction materials, meeting items (agenda), and the like as a bridge display screen, thereby increasing the added value of the material presentation device a0. effective. (3) It can be configured by adding a small-scale circuit or the like to the configuration of the conventional material presentation apparatus, and can be realized without a significant increase in cost. (4) Since the bridge display screen is automatically displayed, the operation is simple and simple.

In implementing the present invention, it is not necessary to be limited to the above-described embodiment, and it goes without saying that various other configurations are possible. For example, the bridge display screen is not photographed by a camera included in the apparatus, but is supplied with image data previously converted into an electronic file from a removable recording medium, or semi-permanently stores in advance as firmware in the apparatus. It is also possible to keep.
Further, when the control unit a32 compares the identification pattern with the live video, the predetermined time for judging that the material does not exist on the data base a2 can be arbitrarily set to be longer or shorter. It may be possible to display the bridge image even during a short time when the exchange is performed.
