Or N times the width of the cutting piece; When N is 3 or more, the width of the transparent line 36 is equal to 2 times (N-1) times the width of cut pieces of each image, and the width of the transparent line 36 and the width of the black line 34. The sum may also provide a three-dimensional stereoscopic imaging apparatus, characterized in that N times the width of the cut pieces of the image.

The present invention is a three-dimensional stereoscopic imaging device composed of the disc 42 and the light film 32, the disc 42 and the light film 32 are respectively installed on the front and back of the transparent plate 44 In addition, the transparent plate 44 may provide a 3D stereoscopic image device made of any one of acrylic, APET, and glass.

The present invention is a three-dimensional stereoscopic imaging apparatus composed of the disc 42 and the light film 32, and also provides a three-dimensional stereoscopic imaging apparatus in which the lighting device 41 is installed behind the disc 42. .

In addition, the present invention will be described in terms of a method of manufacturing a three-dimensional stereoscopic image device consisting of a disc 42 printed with an image, and a light film 32 provided between the disc 42 and the observer,

The disc 42 is produced by synthesizing N images, each of which fixes the photographing focus position F of the camera differently from the center position of the subject, and moves from left to right and photographs from N positions; After N pictures obtained as described above are vertically cut at regular intervals, and the J-th piece of the _K (where 1≤K≤N) th picture CK is (K, J), {( (1,1), (2,2), (N, N)}, {(1, N + 1), (2, N + 2), (N, 2N)}, {(1, X * N + 1), (2, X * N + 2), ... (N, X * N + N)};

The light film 32 is manufactured by alternately arranging transparent lines 36 and black lines 34 having a predetermined width.

In the present invention, in the production of the light film 32, the width of the transparent line 36 is equal to the width of the cut piece of the image and the sum of the width of the transparent line 36 and the width of the black line 34 is Or N times the width of the image cut piece; When N is 3 or more, the width of the transparent line 36 is equal to 2 times (N-1) times the width of the cut piece of the image, and the sum of the width of the transparent line 36 and the width of the black line 34. The 3D stereoscopic imaging apparatus may be manufactured by N times the width of the image cutting piece.

As described above, the present invention improves the production method of the original plate 42 to express the relative perspective of the subjects differently, thereby increasing the three-dimensional appearance of the image and reducing the manufacturing cost by simplifying the structure.

With reference to Figs. 1 and 2, a manufacturing method of the original plate 42 in which perspective between objects is expressed differently will be described. The production of the master plate 42 is performed by photographing a subject at N different positions, obtaining N pictures, and then synthesizing these pictures.

First, the photographing method will be described. In the state in which the subjects are arranged as shown in FIG. 1A, the photographing focus F is fixed to the center of the second subject 12 and the photographs are sequentially taken along the photographing line L spaced a predetermined distance from the photographing focal point F. FIG. Shoot. At this time, the picture taken at the position P _K of K (K is a natural number of 1 or more and less than N) is referred to as C _K and the subject in front of the focusing point F is photographed after the first subject 10 in the focusing point F. If the subject in the third subject 14 is as shown in Fig. 1B, the larger the value of K, i.e., the picture taken while moving to the right, the image of the first subject 10 moves to the left and the third subject 14 Image moves to the right. As the K value increases, the image of the second subject 12 also moves, but since the amount of movement thereof is relatively small, it does not move as shown in FIG. 1B. 1A and 1B illustrate a case in which three subjects and the center of the second subject 12 coincide with the photographing focus F, but the present invention is not limited thereto. In the present invention, it is sufficient to configure one or more subjects by varying the center of the subject closest to the photographing line and the photographic focus (F) position.

Referring to Figs. 2A and 2B, the N photo synthesizing method will be described. First, crop the photo C _K vertically at regular intervals. At this time, in the picture C _K taken at the K th position P _K , when the J th piece from the left is (K, J), {(1,1), (2,2), ... N, N)}, {(1, N + 1), (2, N + 2), ..., (N, 2N)}, ..., ((1, X * N + 1), (2, X * N + 2), ... (N, X * N + N)}.

A manufacturing method of the light film 32 will be described with reference to FIG. The light film 32 is configured to alternately arrange a predetermined width of the black line 34 to block light and a predetermined width of the transparent line 36 to pass the light, and the width of the transparent line 36 is the cutting of each image. It is equal to the width of the piece and the sum of the widths of the transparent line 36 and the black line 34 is N times the width of the cut piece of the image. However, the width of the transparent line 36 and the ratio of the width of the transparent line 36 and the black line 34 are not limited thereto, and the brightness of the image may be adjusted by changing the width and the ratio. The light film 32 makes the original picture look three-dimensionally, and without the light film 32, only the original plate 42 can express the three-dimensional feeling and the sense of distance. That is, through the transparent line 36 of the light film 32, the original photograph photographed at different angles under the same photographing focal point (F) can be seen, thereby obtaining a three-dimensional feeling and perspective through the planar disk drawing. The light film 32 is preferably a polyester material.

Hereinafter, a case in which N is 3 and three subjects will be described with reference to FIGS. 1A and 2B.

The second subject 12 is centered on the photographing focus F, and the first subject 10 is positioned in front of the second subject 12, and the third subject 14 is rearward of the second subject 12. Located in (The front here means that the distance of the subject from the shooting line L is closer than the distance from the shooting line L to the shooting focal point F, and the left side is when looking at the shooting focal point F from the shooting center point M). It means left and rear and right mean the opposite.)

At this time, if the image at one point is an image 1, the image at two points is an image 2, and the image at three points is an image 3, as shown in Fig. 1, the first subject 10 is an image as it goes from image 1 to image 3. The third subject 14 moves to the right, but the second subject 12 hardly moves. However, since the perspective in the parallax barrier method is determined by the amount of movement of the subject in each image, it is possible to obtain an excellent perspective compared to the conventional method.

Each image obtained by the above method is cut vertically with a constant width, and the first piece of image 1 (numbered pieces are assigned sequentially from left to right. The same applies hereinafter). Second image of image 2, image 2 The second draft of the image 3 is followed by the third piece of the image 3 and the third piece of the image 3 and then the fourth piece of the image 1 are joined together to prepare the original draft and print it to create the original plate 42.

The width of the transparent line 36 of the light film 32 is equal to the width of each of the above-described pieces, and the width of the black line 34 of the light film 32 is twice the width of the transparent line 36. . However, in the case where the width of the transparent line is twice the size of each image fragment, the width of the black line 34 is twice the width of each image fragment.

According to the present invention, the transparent plate 44, which is a flat plate, is installed between the disc 42 and the light film 32, thereby serving to support the overall image device, thereby increasing the stereoscopic effect. As the transparent plate 44, it is preferable to use a material having high transparency and high strength such as acrylic or APET, but glass may be used when the size is 600 × 800 mm or less. In this case, a clearer image can be obtained. In the case of producing the billboard by carrying out the present invention, it is preferable to attach the disc 42 and the light film 32 to the front and back surfaces of the transparent plate, and the size of the billboard is (500 × 1000 mm) to (1500 × 3000 mm), the thickness of the transparent plate is preferably 3 to 5 mm.

In the present invention, when the rear of the disc 42 (the opposite direction of the light film 32 relative to the transparent plate 44) is closed, light is blocked and the sharpness of the image is lowered. It is possible to increase the sharpness of the image by installing the lighting device 41 at the rear. The closer the illumination device 41 is to natural light, the better.

Subsequently, the procedure for producing a stereoscopic image (for example, a large outdoor billboard) using the stereoscopic image device according to the present invention is as follows.

1) A photograph with a plurality of lenses coincides with a photographic focal point (F) of each lens, or a subject photographed by fixing a photographic focal position (F) while moving a camera installed on a track.

2) Scan the picture you have taken.

3) In the computer image processing program, each picture is corrected, the color is adjusted, and the three-dimensional picture, the flat picture, and the text are combined to complete the screen corresponding to each picture.

4) Examine the depth and plane depth by composing each screen that has completed the design work into one screen. If you need to adjust the depth and depth of plane, the depth of each screen itself is corrected. The synthesis method of the screen has been described with reference to FIGS. 2A and 2B.

5) Output the synthesized picture to complete the disc 42. There are various methods of the original, such as wide color film, dura film, clear film, and backlit film.

6) The light film 32 is made of a polyester film, the gap between the transparent line 36 and the width of the black line 34 is as described above.

7) The original plate 42 is attached to the back of the transparent plate 44 and the light film 32 is attached to the front of the transparent plate 44, but the engraving portion and the transparent line 36 of the image represented on the original plate 42 ).

8) If necessary, install the lighting device 41 on the back of the disc 42 is a three-dimensional image according to the present invention is completed.

As described above, the present invention improves the production method of the original plate 42 to express the relative perspective of the subjects differently, thereby increasing the three-dimensional appearance of the image and reducing the manufacturing cost by simplifying the structure.
