Description

3D stereoscopic imaging device and its manufacturing method {3-Dimensional Imaging Apparatus and Method of Making Same}

The present invention relates to a three-dimensional stereoscopic imaging apparatus and a manufacturing method thereof.

In recent years, the technology for printing in three dimensions or producing advertisements has been developed by developing a conventional flat advertisement or printed matter. Among various factors that cause a three-dimensional effect, the binocular disparity, which appears and appears about 63mm apart in the human eye, may be the most important factor of the three-dimensional effect. In other words, the left and right eyes see different two-dimensional images, and when these two images are transmitted to the brain through the retina, the brain accurately fuses them with each other to reproduce the depth and reality of the original three-dimensional image. This ability is called stereoography.

As a way of making three-dimensional images have been developed. Among these is the lenticular method. The principle of the lenticular method is to print images or print pictures in alternating vertical patterns, which are to be seen by both the left and right eyes, and view them using an extremely thin vertical cylindrical lens. In this way, the vertical pattern image for the left eye and the vertical pattern image for the right eye are refracted by the vertical lens, so that the image of the left and right eyes is slightly different from each other to obtain a three-dimensional effect.

A more detailed description of the lenticular method is as follows. Humans have two eyes to feel three-dimensional or perspective. The average distance between the eyes is 6.3 cm. When you look at an object, you see the eyes on the left and right sides at the same angle. Since the viewing angles are different, the image seen by the right eye and the image by the left eye are different, each of which is combined as one in the cerebrum and recognized as a three-dimensional image.

Using this principle, a lenticular sheet has been developed for making and printing a plurality of images separately as humans see with left and right eyes, and actually expressing them as seen with right and left eyes, respectively. The lenticular sheet has a shape in which numerous transparent plastic rods having a diameter of 0.3 to 1.3 mm are arranged at an interval of about 0.4 mm, and the lens has a wavy surface. With these lenticular sheets, two images taken from different angles (angles corresponding to binocular parallax for humans) look at each other as if the two images are refracted by a transparent plastic lens and are actually planar and static images. It can be recognized as a dynamic screen.

However, such a lenticular stereoscopic image is difficult to produce a large screen due to its nature, the unit price is expensive, and because it has a disadvantage that can not be built in lighting, it is not suitable for large commercials, it is conventionally large for subway stations or outdoor mangoes It does not apply to advertisements.

The present inventors have studied to solve the shortcomings of the conventional lenticular stereoscopic image, and found that the three-dimensional image is formed by looking at the original picture formed by overlapping a plurality of screens through a light film in which black lines and transparent lines are alternately formed. It has been found that it can be applied to large billboards and that the lighting device can be used as a back light.

Accordingly, it is an object of the present invention to provide a three-dimensional stereoscopic imaging apparatus which can obtain a stereoscopic image at low cost by using a specially manufactured light film and a disc drawing.

Another object of the present invention is to provide a method of manufacturing the 3D stereoscopic image device.

DESCRIPTION OF SYMBOLS 10 Light film 20 Original picture 30 Transparent plate 11: Black line 12 Transparent line 21 Front image 22 Middle image 23 Rear image

1 is an exploded perspective view showing the components of a three-dimensional stereoscopic imaging apparatus (hereinafter, "stereoscopic imaging apparatus") according to the present invention. Referring to FIG. 1, the stereoscopic imaging device includes a light film 10, a circular picture 20, and a transparent plate 30.

The light film 10 is made of a polyester film, it is configured so that black lines and transparent lines are alternately arranged. A description with reference to FIG. In FIG. 2, the light film 10 is composed of a black line 11 and a transparent line 12, and it can be seen that the black line 11 is thicker than the transparent line 12. The light film 10 is to make the original picture (20, which will be described later) synthesized as a planar picture as a three-dimensional screen, and without the light film, only the original picture 20 can express the three-dimensional feeling and the sense of distance. Through the transparent line 12 of the light film 10, each picture taken at different angles, which is synthesized in the original picture 20, is seen, and the transparent picture is installed between the original picture 20 and the light film 10. When the ray 30 in the original picture 20 and the transparent line 12 of the light film 10 are aligned through the plate 30, the planar picture of the original picture 20 is shown as a three-dimensional picture.

The transparent line 12 of the light film 10 displays one picture, and the width of the black line 11 is made 5 to 20 times the width of the transparent line 12, for example, the five-picture picture. When synthesized, the width of the black line 11 is five times the width of the transparent line 12. As a result, the width of the black line 11 is 5 to 20 times the width of the transparent line 12 depending on the number of picture cuts or pictures to be expressed in three dimensions.

The operation of the light film 10 will be described later together with the original picture 20 because it should be described together with the original picture 20.

The original picture 20 is a printed matter or a print film which is enlarged according to a standard by light-working after combining 5 to 10 films into one film or screen. The principle in which a stereoscopic image is represented by the original picture will be described with reference to FIGS. 3A and 3B.

In FIG. 3A, the three-dimensional sense and the sense of distance are represented by three images of the front image 21, the middle image 22, and the rear image 23. FIG. The front image 21 is an object which appears to be forward, the middle image 22 is an object which appears to be located in the middle, and the rear image 23 is an object which is seen backward. As in FIG. 3A, the same method as in FIG. 3B is used to construct a screen.

The front image 21 is made by overlaying a layer of a certain distance to the right by synthesizing the pictures, the rear image 23 is made by overlaying a layer of a certain distance to the left by synthesizing the pictures, the middle image (22) ) Consists of one picture without overlapping.

First, the manufacturing method of the original picture will be described in general.

1) After selecting the ray film and the number of photo cuts, scan the image as many times as the number of screens to synthesize the continuous photographs, pictures, and characters taken from different angles. For example, if you want to combine a picture and text into 5 screens, you need 10 scans for 5 consecutive pictures and 5 texts.

2) Next, by using a computer image processing program (for example, "Photoshop"), one continuous picture and one letter are combined on one screen to make five screens up to five times. In each screen, the front image overlaps with a layer to the right, and the rear image overlaps with a layer to the left. The larger the overlapping interval, the greater the depth and the greater the three-dimensional and distance feeling.

3) Cut the five screens according to the rays and work the beams and combine them into one screen to complete the original picture.

The manufacturing operation of the original picture (that is, the synthesis of several screens) will be described with reference to the example of FIGS. 4A and 4B. FIG. 4A is a conceptual diagram showing a case where a disk picture of a stereoscopic imaging apparatus is made by synthesizing five shots taken from different angles, and FIG. 4B shows a light film required in this case.

1) First, as shown in Fig. 4b, five screen light films are designed. As described above, since the number of photo cuts to be synthesized is 5 cuts, the light film is designed such that the width of the black line is 4 times the width of the transparent line, and the width of the black line and the transparent line is 5 times the width of the transparent line.

2) Cover the light film on the picture 1 and cut the whole picture by the width of the first transparent line of the light film. This is shown in Fig. 4A (A). The black vertical line of FIG. 4A (A) shows the part cut out like the width | variety of each transparent line of FIG. 4B.

3) Place the ray film on the picture 2 and cut out the picture 2 with the width of the second transparent line of the light film. This is shown in Fig. 4A (B). The figure cut out compared with the figure (A) shows that it shifts to the right. Paste this figure 2 and paste it to the right of the figure cut from figure 1.

4) Cover the picture 3 with the light film and cut the whole picture 3 with the width of the second transparent line of the light film. This is shown in Fig. 4A (C). Compared with the diagram (B), the cut out picture is shifted to the right. Paste this cut 3 picture to the right of the cut picture 2 picture.

5) Cover the light film on the picture 4 and cut the whole picture 4 with the width of the second transparent line of the light film. This is shown in Fig. 4A (D). It can be seen that the cut out picture is shifted to the right compared to the (C) diagram. Paste this cut 4 picture to the right of the cut picture.

6) Cover the number 5 film with the light film and cut the entire number 5 with the width of the second transparent line of the light film. This is shown in Fig. 4A (E). It is understood that the cut out picture is shifted to the right in comparison with the diagram (D). Paste this cut 5 picture to the right of the cut picture 4 picture.

7) Thus, five pictures taken from different angles are synthesized to fit the ray of light film (ie transparent line) on one screen.

The transparent plate 30 is a flat plate having a thickness of 3 to 5 mm (see FIG. 1) sandwiched between the light film 10 and the original plate 20 (see FIG. 1), and serves to support the overall image device, and to increase the three-dimensional effect. The transparent plate 30 is preferably made of a material having high transparency and high strength such as acrylic or APET, but may be glass when the size is 600x800 mm or less. In this case, a clearer image can be obtained.

As above, the light film 10, the transparent plate 30, and the picture disc 20 are sequentially arranged, and the picture disc 20 is viewed through the light film 10, in one transparent line of the light film 10. You can see five pictures on the original picture, and you can see the image that is three-dimensional and sense of distance as a whole. Although the lighting device is not shown in FIG. 1, the lighting device is installed at the rear of the picture disc 20, so that a more effective screen can be seen.

In practice, the procedure for producing a large stereoscopic image (for example, a large outdoor billboard) using the stereoscopic imaging apparatus according to the present invention will be described below.

1) A camera with three to five lenses takes three to five pictures of the subject at three to five angles. Alternatively, 5-20 pictures are taken at 5 to 20 angles on a three-dimensional track.

2) Scan the picture you have taken.

3) In the computer image processing program, each picture is corrected, the color is adjusted, and each screen is completed by synthesizing three-dimensional, planar pictures, and characters.

4) According to the number of photos, make a light film and print specially on polyester film.

5) Combining each screen that has completed the design work into one screen and inspecting the depth and plane depth. The screen synthesis method has been described with reference to FIGS. 4A and 4B. If you need to adjust the depth and depth of plane, the depth of each screen itself is corrected.

6) From the rays printed on the polyester film, select the appropriate rays considering the screen size and depth. For each screen, combine the rays to make a picture screen with rays.

7) Print the original picture. There are many different types of originals, including wide color film, dura film, clear film, and backlit film.

8) Attach the original picture on the back of the transparent plate, and attach the ray film to the front of the transparent plate according to the ray of the original picture.

9) If the lighting device is installed on the back of the original picture as needed, the three-dimensional image using the three-dimensional stereoscopic image device according to the present invention is completed.

The embodiment of the stereoscopic image according to the present invention employs a mixture of the front image 21, the middle image 22, and the rear image 23, and only the middle image 22 and the front image 21, or the middle image. With only the 22 and the rear image 23, a desired three-dimensional effect can be obtained by mixing the three characters by pushing or pulling only a specific image or portion forward and backward. Therefore, the scope of the present invention is not limited by the embodiments described in the detailed description or drawings of the present invention, and it goes without saying that the scope of the present invention is obvious to those skilled in the art.

As described above, according to the three-dimensional stereoscopic imaging apparatus according to the present invention, unlike the conventional flat printing, it is possible to focus people's eyes with a three-dimensional and vivid image, reduce the production cost and produce a large screen, Advertising effect is greatly improved.
