FIG. 1 is a configuration diagram schematically showing a configuration of a lighting board system according to an embodiment.

1, a lighting board system according to an embodiment includes a board unit 1, a first lighting unit 21, a camera unit 3, a mirror unit 4, and a control unit 5 .

The board unit 1 has a first surface 11 and a second surface 12 opposed to each other and a third surface 13 extending to connect the edges of the first surface 11 and the second surface 12, As shown in FIG. 2, may be formed as a flat flat plate. The first surface 11 is a surface facing the user 7 and the second surface 12 is a surface facing the first surface 11 in the first direction D1. And the third surface 13 may be a corner surface formed at the edges of the first surface 11 and the second surface 12. [

The board unit 1 is preferably arranged to transmit light along at least a first direction D1 so as to face the first side 11 in a direction opposite to the second side 12 The appearance of the user 7 can be observed. The board unit 1 may be formed of a transparent glass material or a transparent plastic material.

The board unit 1 is provided on the first surface 11 so that the user 7 can input the input by the input tool. The input tool may be a pen including a fluorescent pigment.

The first surface 11 may be rougher than the surface of the second surface 12 so that marking by the input tool can be performed more smoothly. In this case, however, it is preferable that the light transmittance of the board unit 1 is not excessively decreased.

The first lighting unit 21 is positioned to face at least a part of the third surface 13 and is provided to irradiate light in a second direction D2 as viewed in Fig. It suffices that the first lighting unit 21 is provided so as to irradiate light on an area corresponding to the input area 14 which is mainly input by the user among the first surface 11.

3, the first lighting unit 21 includes a first light source 211 positioned opposite to the third surface 13 and a second light source 211 positioned between the third surface 13 And a second light guide 212 facing the first light guide 212. The first light guide 212 is coupled to the edge of the third surface 13 and guides the light of the first light source 211 toward the third surface 13 without leaking outward. The first light guide 212 may be coupled along the third surface 13, as shown in FIG. 2, and may be formed to cover the entire third surface 13 according to an embodiment.

When the first lighting unit 21 irradiates light into the board unit 1 through the third surface 13 and the user 7 writes on the first surface 11 by the input tool , The contents input on the first side 11 are illuminated with a fluorescent color, and thus can be viewed more clearly by the viewer. In addition, the contents inputted by the user 7 are confirmed on the second surface 12, so that they are always present on the front surface of the user 7 positioned opposite to the first surface 11, So that the input content is not seen.

The camera unit 3 is located in front of the second direction 12 in the first direction D1 and is positioned so as to be spaced apart from the second plane 12. [ It is preferable that the camera unit 3 is arranged such that the imaging direction 31 thereof is directed in the second direction D2. Thus, the camera unit 3 can photograph the mirror unit 4 positioned in front of the camera unit 3.

It is preferable that the mirror unit 4 is located in front of the imaging direction 31 of the camera unit 3 and at least the reflection surface 41 thereof is inclined in the first direction D1 and the second direction D2 desirable. 1, the reflecting surface 41 of the mirror unit 4 may be at 45 degrees with respect to the first direction D1 and the second direction D2, respectively. 2, the mirror unit 4 may be formed to extend in a third direction D3 perpendicular to the first direction D1 and the second direction D2, May correspond to the length (1) of the board unit (1) in the third direction (D3). Accordingly, when the camera unit 3 photographs the reversed image through the mirror unit 4, it is possible to prevent part of the image from being deviated from the image. However, the present invention is not necessarily limited to this, and the mirror unit 4 may further include a convex lens and / or a concave lens so that the camera unit 3 can capture an image transmitted through the board unit 1 with a small size .

The mirror unit 4 may be coupled to the camera unit 3 using a separate jig 42, as shown in FIG. The jig 42 can be coupled to the mirror unit 4 so that the angle of the mirror unit 4 can be changed.

1, the user 7 can lecture while inputting specific contents to the first side 11 located on the front side of the user 7 while looking at the front side, (3). At this time, the scene of the steel is inverted through the mirror unit 4, and the inverted image is taken through the camera unit 3. Therefore, when the user 7 inputs a specific content including a character on the first side 11, the viewer who sees the video will see the reversed video, so that the character appears originally.

The first image data, which is the inverted image, is transferred to the first image generating unit of the control unit 5 electrically connected to the camera unit 3, and the first image generating unit generates the first image data from the first image data, And provides it to the viewer. Therefore, without any editing process, the viewer can view the video of the lecture being shot in real time.

Meanwhile, the control unit 5 may be electrically connected to an image reproducing unit 6 for reproducing second image data different from the first image data. The image reproducing unit 6 can reproduce the second image data that the user 7 can use as the lecture data, not the image taken by the camera unit 3. [ The second image data may be various video images, internet images, and / or presentation images. The image reproducing unit 6 may be provided in an apparatus separate from the control unit 5, but the present invention is not limited thereto and may be provided in the same apparatus as the control unit 5. [ The image reproducing unit 6 may be a part of a memory or a memory equipped with a video reproducing program.

The first image generating unit 51 generates a first image layer 511 as shown in FIG. 6 with the first image data generated from the camera unit 3 as described above, (52) receives second image data from the image reproducing unit (6) and generates a second image layer (521). The third image generation unit 53 generates a third image layer by superimposing the first image layer 511 and the second image layer 521 on each other. The third image layer thus generated is stored in a separate storage unit (not shown) and is provided to the viewer. Accordingly, the third image layer, which is a lecture image viewed by the viewer, is an image in which the first image layer, which is a lecture image, is overlapped with a second image layer, which is a supplementary image of a separate lecture, Therefore, it can be a more stereoscopic image that shows various river effects. For example, when the user 7 who is a lecturer conducts a chemical lecture, the user 7 can enter a lecture on the first side 11 of the board unit 1 for a chemical formula, And a stereoscopic image of the chemical structure is generated as a second image layer, and a third image layer having the two image layers superimposed to the stereoscopic image of the chemical structure can be generated as a final image.
