Abstract

PURPOSE:To use an original as a superimposing original as it is without replotting on a specific sheet even in case of the original such as a paper by superposing the image of other original on a prescribed original by a magic mirror. CONSTITUTION:The original 1 and the superimposing original 2A are respectively mounted on stages 3a, 3b. The magic mirror 9 transmits the image of the original 1 from a mirror 5 to a mirror 6 to superpose the image of the superimposing original 2A on the image of the original 1 from the mirror 5 and display the synthesized image on a monitor photographed by a camera 4. Since the original such as the paper can be used as the superimposing original 2A as it is, it is not required to prepare separately the transparent specific sheet to realize the efficiency of an operation.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a video presentation device having a superimpose function for presenting a video to be displayed on a video display device such as a monitor.

[Prior Art] Fig. 2 is a block diagram showing a conventional video presentation device.
is the superimpose manuscript superimposed on manuscript 1 [3rd
(see figure (b))], characters are written on a special transparent sheet. 3 is a stage on which the originals 1 and 2 are placed, and 4 is a composite image of the originals 1 and 2 on the stage 3 reflected by a mirror 5 and 6 [so-called superimposed image; See number 8 in Figure 3 (C)]
7 is a monitor serving as a video display device for displaying images of the originals 1 and 2 taken by the camera 4.

Next, the operation will be explained.

When superimposing is not performed, by placing the original 1 to be visualized on the stage 3, the image of this original 1 is captured by the camera 4 via the mirrors 5 and 6 and along the projection path shown by the broken line. It will be done.

The image taken by the camera 4 is then displayed on the monitor 7.

Further, when superimposing is performed, the superimposing original 2 is further superimposed on the original 1 placed on the stage 3 as described above.

The image of the original 2 for superimposition drawn on a transparent special sheet is combined with the image of the original 1. Thereafter, the composite image 8 is photographed by the camera 4 and displayed on the monitor 7 in exactly the same manner as described above. As a result, the superimposed video cannot be displayed.

[Problems to be Solved by the Invention] Since the conventional video presentation device is configured as described above, a special transparent sheet is used to superimpose the original 2 on the original 1. If you try to superimpose a manuscript drawn on opaque material such as paper, it is necessary to redraw it on a new special sheet, which is cumbersome and inefficient. There were problems such as:

This invention was made to solve the above-mentioned problems, and even if the original does not use a special sheet, it can be easily superimposed without having to redraw it. The purpose is to acquire equipment.

[Means for Solving the Problems] In the video presentation device according to the present invention, an image to be converted into a video signal is placed on a projection path leading to the camera.

At least one one-way mirror is arranged so that an image of another document is superimposed on an image transmitted through the one-way mirror from behind the one-way mirror.

[Function] In the video presentation device of the present invention, images of other documents are superimposed on a predetermined document using a magic mirror to perform superimposition. It can be used as it is as a manuscript for superimposition without having to redraw it on the special sheet 1-.

[Embodiment of the Invention] Hereinafter, an embodiment of the present invention will be described with reference to the drawings. 1st
The figure is a block diagram showing a video presentation device according to an embodiment of the present invention. In FIG.
3(a)], 2A is a superimposition manuscript [see FIG. 3(b)), 3a.

3b is a stage for placing the originals 1 and 2A, respectively, and 4 is a composite image of the originals 1 and 2A [so-called superimposed image: see reference numeral 8 in FIG. 3(Q)]
5 and 6 are mirrors that reflect and guide the image of the document 1 on the stage 3a to the camera 4; 7 is the fMmL 2A photographed by the camera 4;
9 is a one-way mirror placed on the projection path (see broken line) of the image of the original 1 between the mirrors 5 and 6; The image of the superimposing original 2 is superimposed on the image of the original 1 transmitted through the magic mirror 9, and is projected onto the camera 4 via the mirror 6.

Next, the operation of the apparatus of this embodiment will be explained.

When superimposing is not performed, the original 1 to be visualized is placed on the stage 3a, as in the conventional apparatus, and the image of the original 1 is projected onto the projection path shown by the broken line via the mirrors 5 and 6. The image is then captured by camera 4. The image taken by the camera 4 is then displayed on the monitor 7.

Also, when performing superimpose.

The original 1 and the superimpose original 2A are placed on stages 3a and 3b, respectively. At this time, the magic mirror 9 transmits the image of the original 1 from the mirror 5 toward the mirror 6, and superimposes the image of the superimposing original 2A on the image of the original 1 from the mirror 5. An image synthesized in this manner is photographed by the camera 4 and displayed on the monitor 7. As a result, the superimposed video is displayed.

In this way, according to the device of this embodiment, by placing the magic mirror 9 on the projection path, even if the image is of a document such as a single sheet, it can be superimposed as it is without having to redraw it on a new special sheet. Since it can be used as the original document 2A for other purposes, there is no need to separately prepare a special transparent sheet as in conventional devices, and work efficiency can be improved.

In the above embodiment, the document 1 is placed on the stage 3a and the superimpose document 2A is placed on the stage 3b, but the placement conditions may be reversed.

Further, in the above embodiment, the mirrors 5, 6 . Magic mirror 9. Camera 4. Although the arrangement of the originals 1, 2A, etc. is shown in FIG. 1, the positional relationship is not limited to this. Not restricted at all.

Further, in the above embodiment, the case where only one magic mirror 9 is provided has been described, but a plurality of magic mirrors may be arranged on the projection path.

In this case, images of multiple originals can be superimposed.

[Effects of the Invention] As described above, according to the present invention, by arranging the one-way mirror on the projection path, even images of documents such as paper can be directly superimposed without having to be redrawn on a new special sheet. Since it is configured so that it can be used as a manuscript for imposition, there is no need to separately prepare a special transparent sheet as in the conventional apparatus, and there is an effect that efficiency of one operation can be realized.
