The 3D image is provided by arranging the image area of the person corresponding to the closest to the observer's gaze so that the virtual images corresponding to the images of the objects of different importance overlap each other with different perspectives in the observer's field of view. can do.

In this case, the area of the semi-transparent mirror may be configured to be wider as the closer to the observer, so that the object of high importance reflects through a larger area, thereby emphasizing the object of high importance and simultaneously with the object of low importance. Perspective can be further doubled.

Based on the above description, the configuration of the 3D image providing apparatus according to the present invention will be described in detail with reference to the drawings.

1 is an external perspective view and an internal perspective view of a 3D image providing apparatus according to the present invention. First, referring to the external perspective view of FIG. 1A, the 3D image providing apparatus according to the present invention may include a darkroom having an opening 10. The dark room 100 includes a storage space for mounting or receiving the display apparatus 200 for providing a 2D image, and a plurality of semi-transparent mirrors disposed at predetermined inclinations on the storage space. (110, 120, 130).

Accordingly, when the display apparatus 200 is accommodated in the storage space, the plurality of translucent mirror parts 110, 120, and 130 may be disposed with a predetermined inclination with respect to the screen of the display apparatus 200. have.

Each of the translucent mirrors 110, 120, and 130 may provide a virtual image generated by reflecting an image output through the display apparatus 200 to the opening 10 of the dark room to the observer's field of view 1. Can be.

In this case, the dark room 100 is gradually widened toward the opening 10 and is provided with a space composed of a wall for absorbing light, thereby increasing the sharpness of the virtual image generated by the translucent mirrors 110, 120, 130. Can be.

The display apparatus 200 accommodated in the storage space may include a tablet PC.

In addition, the display apparatus 200 may divide and output the 2D image into a plurality of image regions. In this case, the 2D image may be composed of contents to be felt in a plurality of image areas, and the display apparatus 200 may output the content as it is without segmentation.

In addition, the display apparatus 200 may output an image composed of different objects in each image area, thereby making it possible to clearly distinguish the image from the image output in another image area. In this case, the object may be output by being matched to different image areas according to importance and, for example, may be divided into objects such as a background, an object, and a person.

In this case, the division of the 2D image is preferably divided in the horizontal direction as shown in Fig. 1 (b), it is preferable that each of the divided image area to output a different image.

In addition, the lower end portions of the translucent mirror portions 110, 120, 130 may be disposed to meet the lower end portions of the corresponding image regions, and the translucent mirror portions 110, 120, 130 may be disposed in the corresponding image regions. It may have a predetermined slope to reflect the image to the opening.

In addition, when the two-dimensional image is divided into a plurality of image areas having the same area, the plurality of translucent mirror parts 110, 120, and 130 reflects the image output from each image area. The translucent mirrors 110, 120, and 130 may be arranged with different inclinations.

Meanwhile, referring to FIG. 2, the plurality of translucent mirror parts 110, 120, and 130 may be configured to have different areas. That is, among the virtual images represented by the observer's field of view through each of the translucent mirrors 110, 120, and 130, the area of the translucent mirrors 110, 120, and 130 with respect to the object is increased as the object having a higher importance according to the importance of the object. This makes it possible to clarify the distinction from less important objects and double the perspective with less important objects. Detailed description thereof will be described below with reference to FIG. 4.

For example, as shown in FIG. 2, the area of the first semi-transparent mirror 110 corresponding to the image region for the object of high importance is the largest and the second semi-transparency corresponding to the image region for the object of medium importance. The area of the mirror unit 120 may be configured in the middle, and the area of the third semi-transparent mirror unit 130 corresponding to the image area of the object of low importance may be configured to be the smallest. Accordingly, the virtual image for the object of high importance may be emphasized by changing the size of the virtual image reflected through the plurality of translucent mirror parts 110, 120, and 130.

In addition, each of the translucent mirrors 110, 120, and 130 is disposed adjacent to the opening as the area is larger, and thus the translucent mirrors 130 having the smallest area may be disposed farthest from the opening.

Accordingly, the virtual image generated through the first translucent mirror 110 adjacent to the opening is most clearly output, and the virtual image generated through the third translucent mirror 130 located farthest from the opening is the first image. Since the sharpness is lower than that of the virtual images generated through the first to second semi-transparent mirrors 110 and 120 while passing through the second semi-transparent mirror portion 120 and the third semi-transparent mirror portion 130, To highlight the video.

In this case, the plurality of translucent mirror parts 110, 120, and 130 may be configured to have different transmittances in order to ensure the maximum clarity of the virtual image generated through the third translucent mirror part 130.

For example, the virtual image generated through the third translucent mirror 130 must pass through all of the first to second translucent mirrors 110 and 120, so that the transmittance of the third translucent mirror 130 is the best. Low, the virtual image generated through the second translucent mirror portion 120 must pass through the first translucent mirror portion 110 and the second translucent mirror portion 120 of the third translucent mirror portion 130 Since the virtual image needs to be transmitted, the transmittance is configured to be intermediate. The virtual image of the first semi-transparent mirror 110 is not transmitted to the observer's view as it is, and the first semi-transparent mirror 110 includes second to third translucent mirrors ( Since the virtual images of 120 and 130 must be transmitted, the transmittance can be configured to be the highest.

That is, the relationship between the area and the transmittance of the plurality of semi-transparent mirrors 110, 120, 130 can be configured in inverse proportion.

In this case, since the third semi-transparent mirror part has no virtual image to be transmitted, it may be replaced with a general mirror.

That is, the translucent mirror located farthest from the opening of the dark room may be configured by replacing the ordinary mirror with no transmission.

Meanwhile, as shown in FIG. 2, when the plurality of translucent mirror parts 110, 120, and 130 are disposed at the same angle with respect to each of the image areas, the display apparatus 200 as shown in FIG. 3. The plurality of divided image regions output from may be configured to have different areas, and as described above, each image region may output an image of an object having different importance.

For example, the A image area for the object of least importance may output an image of the background, and the B image area for an object of medium importance may output an image of an object, and the object of highest importance. The C image region for may output an image of a person.

That is, an object of higher importance may secure a wider image area to provide a visually closer and clearer image.

Based on the above configuration, for example, when a picture book is three-dimensional, it is possible to easily distinguish the background from the surrounding composition and the main character, and to easily realize the three-dimensional effect by displaying them by matching them to each area, thereby increasing the concentration. Can be improved.

FIG. 4 is a diagram illustrating an example of a perspective view of a virtual image generated by the translucent mirror unit, wherein a two-dimensional image including a plurality of image regions output from the display apparatus includes different objects for each image region. You can print

In this case, even though the objects output from the image areas A, B, and C of FIG. 4A have the same size, they are generated through the semi-transparent mirrors a, b, and c corresponding to the image areas. Since the virtual image is generated to have a perspective to the observer's field of view, the virtual image generated by the translucent mirror portion (c) closest to the observer's field of view is most visible, and the virtual image generated by the translucent mirror portion (a) located at the farthest distance. Will look the smallest.

In addition, an object of high importance is output to an image area having a larger area, and the area of the semi-transparent mirror portion is also proportional to the area of the image area, so that the size of an object of high importance is displayed differently from an object of low importance. It can also maximize utilization.

Accordingly, as shown in FIG. 4 (b), the perspective between the objects of high importance and the objects of low importance is guaranteed as described above, and the larger objects are displayed with larger sizes to display the degree of perspective. You can multiply it further.

5 is a view showing another embodiment of a three-dimensional image providing apparatus according to the present invention, as shown in Figure 5 (a) is composed of a plurality of layers on the lower surface of the dark room, to accommodate a display device of different sizes Alternatively, a plurality of storage spaces C and D for mounting may be configured.

In this case, as shown in FIG. 5B, the first storage space C may have a space corresponding to the size of the display device, and may be inserted to occupy the entire space of the display device 200. In addition, the second storage space D may accommodate the terminal 210 smaller than the size of the display apparatus 200.

On the other hand, as shown in Figure 5 (c) is provided with a magnifying glass such as a Fresnel lens 300 in the lower portion of the first storage space, and output to the terminal 210 inserted in the second storage space (D) The image to be enlarged through the magnifying glass may be provided to the translucent mirror unit.

Accordingly, the image of the terminal 210 is divided into a plurality of image regions, similar to the image of the display apparatus 200, so that each image region corresponds to the image region of the display apparatus 200. By enlarging through 300 to provide the translucent mirror unit, a plurality of images corresponding to the plurality of image regions may be provided.
