An exemplary embodiment of the present invention is to provide an apparatus and method for optimizing a screen division using 3D data capable of generating a hologram by reflecting a hologram object to a polyhedron.

In general, reflective holograms are specially made for holograms, or hologram images can be implemented using 3D data and 3D viewers.

The planar decomposer generation unit may generate the planar decomposers by inverting the screen and text in the canvas so as to be normally expressed when the hologram of the floating method is implemented as an actual hologram.

In the process of arranging the planar decomposers on each of the center canvas and the left and right canvases, the planar decomposer optimizer may be arranged to match the first center of each planar decomposer and the second center of the circle inscribed to each canvas. .

The planar decomposer optimizer may enlarge the sizes of planar decomposers disposed on each of the center canvas and the left and right canvases by the size of a circle inscribed in the center canvas.

When the length is greater than the horizontal length, the first center may be moved upwards by a specific distance, and then the size of the planar decomposition body may be enlarged in the boundary direction of the central canvas based on the first center.

FIG. 3 is a block diagram illustrating the functional configuration of the screen division optimization device in FIG. 1.

Referring to FIG. 3, the screen division optimization device 130 includes a canvas generation unit 310, a planar decomposition unit 330, a planar decomposition unit optimization unit 350, a hologram object generation unit 370, and a control unit 390 ).

The canvas generator 310 may generate a plurality of canvases forming a screen area of the flat panel display panel. Here, the flat panel display panel may correspond to a display device that outputs an image or image of a 3D object. At this time, the output of the image or image related to the 3D object may correspond to the output of the hologram target object corresponding to the 3D object. In one embodiment, the user terminal 110 may be implemented as a component of the screen division optimization device 130, in which case the user terminal 110 may serve as a flat panel display.

In one embodiment, each of the plurality of canvases may be formed in a trapezoidal shape or a triangular shape corresponding to a reflective surface on which the hologram object is reflected. Here, the reflective surface may correspond to a plane performing an operation of reflecting an area of a hologram object and transmitting the remaining area of the area output to the canvas to generate a hologram. That is, the plurality of canvases may be implemented in the same size and shape corresponding to the reflective surface, and generally may be formed in a trapezoidal shape or a triangular shape according to the shape of the reflective surface, but are not limited thereto, and have a shape corresponding to the reflective surface. Of course, it can be formed by deformation.

In one embodiment, the canvas generator 310 may generate at least one center canvas and left and right canvases symmetrically formed on both sides of the center canvas in a developed view manner. For example, the canvas generator 310 may generate four-sided canvases in a developed manner so that they can be used in a hologram device composed of four reflective surfaces, and in this case, each canvas may be generated as a triangle having the same shape. There are two center canvases formed symmetrically and left and right canvases.

In addition, the canvas generator 310 may generate three-sided canvases in a developed manner so that it can be used in a hologram device composed of three reflective surfaces, in which case the central canvas may be formed in a triangle or trapezoid, and the left and right canvases They may be formed in a triangular or trapezoid shape corresponding to the central canvas, and may be composed of one central canvas and left and right canvases. Meanwhile, at least one central canvas and left and right canvases may be disposed on the same plane to form a square-shaped flat display screen.

The planar exploded body generating unit 330 may generate planar exploded bodies in which a 3D object is exploded in at least three directions. To this end, the screen division optimization device 130 may store 3D data related to a 3D object in the database 150, and the planar decomposition generator 330 based on the 3D object obtained from the database 150 Can produce planar decomposition bodies. Here, the planar exploded body may correspond to a 2D image looking at a 3D object in a specific direction.

More specifically, the planar decomposer generator 330 may obtain a planar decomposer corresponding to the 2D image according to a preset direction by the screen division optimization device 130 using the stereoscopic data regarding the 3D object. At this time, the generated 2D image may correspond to images of various sizes and shapes corresponding to the same 3D object. The planar decomposed body generating unit 330 may generate a planar decomposed body corresponding to each direction based on the generated 2D image.

In one embodiment, the planar decomposition body generating unit 330 may irradiate a 3D object in real time from at least three directions to increase the realism of the hologram target object when the hologram image is changed by a user input. The planar decomposition generator 330 may acquire a 2D image of a 3D object from stereoscopic data of the 3D object, and then apply a light effect to the 2D image. The light source effect may be formed by placing a 3D object on a 3D space and then irradiating the light source in a preset direction, and the planar decomposition generator 330 canvases based on the 2D image in the state where the light source effect is applied. It is possible to create a planar decomposition body disposed in a phase.

That is, the planar decomposition body generation unit 330 forms a 3D object from the stereoscopic data related to the 3D object, irradiates the light source in real time to the 3D object in a preset direction, and then in each direction based on the 3D object with the light effect applied Planar decompositions can be generated. In the case of a general hologram method, it is difficult to dynamically change the light source effect in the process of forming the hologram because the hologram is generated by simply reproducing the hologram image itself to which the light source effect is applied, whereas the screen division optimization device 130 according to the present invention Since the light effect can be dynamically applied in the process of generating the hologram target object for the 3D object, it can have the advantage of being able to freely change the number, direction, and intensity of light sources.

In one embodiment, the planar decomposer generator 330 may reflect the light source reflected in each of at least three directions to all planar decomposers. For example, the hologram can be expressed in three dimensions due to its characteristics, and thus, in the case of a light source reflected in a 3D object in a specific direction, it can also have an effect on a planar decomposition body formed on a reflective surface around the direction.

In this case, a direct light effect and an indirect light effect can be independently applied to the reflective surface on which the planar decomposition body is formed, and the indirect light effect is based on the assumption that the reflective surface forming the hologram is transparent. It may correspond to the effect of the light source passing through the slope. As a result, the effects of all light sources can be directly or indirectly applied to all planar decomposers forming the hologram object.

In one embodiment, the planar decomposer generator 330 may generate planar decomposers by inverting the screen and text in the canvas so as to be normally expressed when a hologram of a floating type is implemented as an actual hologram. The floating type hologram may reflect the hologram image on a reflective surface in order to implement the hologram, and thus a left and right inversion effect may be applied to the reflected image based on a direction viewed by users. The planar decomposer generation unit 330 may invert the screen and the text, respectively, in the process of generating the planar decomposers so as to be normally expressed when implemented as an actual hologram.

The planar decomposer optimizing unit 350 may arrange planar decomposers to match each of the plurality of canvases and optimize each planar decomposer to fit the canvas size. The screen division optimization device 130 may generate each canvas to correspond to the reflective surface on which the hologram is formed, and the planar decomposition optimizer 350 may adjust the size and position of the planar decomposers within each canvas by appropriately adjusting the user. It is possible to maximize the size of the actual hologram they are viewing and minimize the size of the wasted area in the screen area where the hologram target object is output.

In one embodiment, the planar decomposer optimizer 350 may determine the position and size of the planar decomposers disposed on each of the center canvas and the left and right canvases based on the aspect ratio of the 3D object and the shape of the plurality of canvases. . Each of the plurality of canvases may be formed in a trapezoidal or triangular shape, but the angle that each corner forms with the base may be fixed at 45 degrees. Therefore, when the planar decomposer is placed on each canvas in a general manner, the size of the planar decomposer can be determined regardless of the horizontal and vertical length ratio of the hologram target object. In this case, the size of the hologram viewed by the user will be small. In addition, there may be a problem that a large number of areas are wasted in the screen area.

To solve this, the planar decomposer optimizer 350 determines the position and size of the planar decomposers disposed on each of the center canvas and the left and right canvases based on the aspect ratio of the 3D object and the shape of the plurality of canvases. Minimizes the wasted area and enlarges the size of the actual hologram. The screen division optimization device 130 may obtain information about a 3D object based on 3D stereoscopic data.

In one embodiment, the planar decomposer optimizer 350 sets the first center of each planar decomposer and the second center of the circle inscribed in each canvas in the process of placing the planar decomposers on each of the center canvas and the left and right canvases. It can be arranged to match each other. That is, the planar decomposer optimization unit 350 may determine the basic position of the planar decomposer within the canvas by matching the centers of the planar decomposers to the center of the circle inscribed to each canvas for each of the center canvas and the left and right canvases. have.

In one embodiment, the planar decomposer optimizer 350 may enlarge the sizes of the planar decomposers disposed on each of the center canvas and the left and right canvases by the size of a circle inscribed in the center canvas. When the basic position of each planar decomposed body is determined in each canvas, the planar decomposed body optimization unit 350 may optimize the size of the planar decomposed body by expanding the size of each planar decomposed body by the size of a circle inscribed in each canvas. have.

In one embodiment, the planar decomposer optimizer 350 moves the first center down a specific distance when the horizontal length of the 3D object is greater than the vertical length, or the vertical length of the 3D object is greater than the horizontal length In this case, the first center may be moved up a certain distance, and then the size of the planar decomposition body may be enlarged in the boundary direction of the center canvas based on the first center.

More specifically, the planar decomposer optimizer 350 may primarily determine the size of the planar decomposer by matching the second center of the circle inscribed to the central canvas with the first center of the 3D object. If the 3D object has a long shape in the vertical direction, the screen utilization may be increased by moving the position of the first center upward by a predetermined distance and then expanding the size of the planar decomposition body in consideration of the vertical length of the canvas. If the 3D object has a long shape in the horizontal direction, the screen utilization may be increased by moving the position of the first center down a predetermined distance and then expanding the size of the planar decomposition body in consideration of the horizontal length of the canvas.

At this time, the planar decomposer optimizer 350 may determine a specific distance for moving the position of the first center according to the horizontal and vertical length ratios of the 3D object. That is, as the difference between the horizontal and vertical lengths increases, a specific distance may also increase.

In one embodiment, the planar decomposer optimizer 350 determines the size and position of the left and right planar decomposers disposed on each of the left and right canvases so as to correspond to the planar decomposers disposed on the center canvas, and the horizontal center of the left and right planar decomposers. The axis can be moved down a predetermined distance. The planar decomposer optimizer 350 may primarily optimize the planar decomposer with respect to the central canvas, and optimize the planar decomposer with respect to the left and right canvases based on this.

Therefore, the planar decomposition bodies respectively formed on the left and right canvases may be generated corresponding to the position and size of the planar decomposition bodies formed on the central canvas. The planar decomposition body optimization unit 350 may utilize size information and corresponding information about the canvases generated by the canvas generation unit 310.

In addition, the planar decomposition body optimization unit 350 may move the horizontal center axis of the left and right planar decompositions formed corresponding to the planar decomposition formed on the central canvas by a predetermined distance down. Through this, the planar decomposition body optimization unit 350 may prevent a phenomenon in which a part of the hologram is not formed on the reflective surfaces disposed on the left and right sides. The screen division optimization device 130 may set and use a moving distance in relation to the horizontal center axis of the left and right flat decomposers according to the enlargement ratio of the flat decomposer.

The hologram object generating unit 370 may generate a hologram target object by providing planar decomposition objects to the flat display panel. Here, the object to be hologram may correspond to a transform object of a 3D object in which planar decomposition bodies are respectively reflected on a reflective surface to generate a hologram. The hologram object generated by the hologram object generation unit 370 may be output through a flat panel display panel. That is, the hologram device may form a hologram for the 3D object by outputting the hologram target object through the flat display panel and reflecting only the hologram target object by the reflective surface.

In one embodiment, the hologram object generation unit 370 may control to update the generated hologram target object when the 3D object is controlled according to the user's control. At this time, the user's control may be performed through the user terminal 110, or may be performed through a control interface provided by the screen division optimization device 130.

For example, in the hologram device, the hologram object generation unit 370 updates the plane decomposition objects disposed on each canvas so that the 3D hologram object can rotate by reflecting the rotation angle when the 3D object is rotated by the user control. You can. The update operation for the planar decomposer performed by the hologram object generating unit 370 may be performed through the iterative execution of a process ranging from creation of the planar decomposer within each canvas, placement and optimization, and creation of the hologram target object. .

The control unit 390 controls the overall operation of the screen division optimization device 130, the canvas generation unit 310, the plane decomposition body generation unit 330, the plane decomposition body optimization unit 350, and the hologram object generation unit 370 ) Can manage the control flow or data flow.

Referring to FIG. 4, the screen division optimization device 130 may generate a plurality of canvases forming a screen area of the flat panel display through the canvas generation unit 310 (step S410). The screen division optimizing device 130 may generate planar decomposed objects in a developed manner in which the 3D object is decomposed in at least three directions through the planar decomposer generator 330 (step S430).

In addition, the screen division optimization device 130 may arrange the planar decomposers to match each of the plurality of canvases through the planar decomposer optimizer 350 and optimize each planar decomposer (step S450). The screen division optimization device 130 may generate the hologram target object by providing the flat decomposition bodies to the flat display panel through the hologram object generation unit 370 (step S470).

5 and 6 are views illustrating a trapezoidal canvas and a planar exploded body.

Referring to FIG. 5, the screen division optimizing device 130 uses the flat decomposition objects 570a, 570b, and 570c in which the 3D object is decomposed in at least three directions through the flat decomposition object generation unit 330. Can be created. Figure (a) is a planar decomposition body (570a, 570b, 570c), and planar decomposition bodies (570a, 570b, 570c) to appear as a hologram and the reflective surface area 590 used in the screen division optimization device 130 Corresponding to the drawing illustrating the structure between the canvases 510, 530, and 550, which are areas included and output through the flat panel display panel, the figure (b) and the reflective surface area 590 used in the hologram of the general floating method It may correspond to a drawing for explaining canvases 510, 530, and 550 including the supporting supports to be reflected.

In Figure (a), the screen division optimization device 130 is a pyramid or an inverted pyramid floating hologram in the form of a physical area (trapezoid or triangle) to be reflected on a reflective surface and a planar decomposition that is an image to be reflected. By matching the shape of, it is possible to increase the size of the planar decomposer forming the hologram.

On the other hand, the screen area in which the sizes of the canvases 510, 530, and 550, which are areas including the image to be reflected, are displayed in comparison with the size of the area to be reflected on the actual reflection surface in the figure (b), is rectangular (including a square). ), It is smaller than the entire area to be reflected, so the reflected and projected hologram images have a small problem. If the central canvas 530 is made large, the size of the left and right canvases 510 and 550 may be reduced or a hologram image may be overlapped.

Referring to FIG. 6, the screen division optimizing device 130 may generate planar decomposed objects 630 of a development method in which a 3D object is decomposed in at least three directions through the planar decomposer generator 330, The planar decomposer 630 may be arranged to match the planar decomposers 630 to each of the plurality of canvases 610 and optimize the planar decomposers 630. Figure (a) shows the relationship between the size of the triangle-shaped canvas 610 and the size of the planar decomposition body 630 when the planar decomposition objects 630 are generated based on the 3D object by the screen division optimization device 130. In addition, the figure (b) expresses the relationship between the size of the canvas 610 and the size of the planar decomposition body 630 in a general hologram device.

The figure (a) describes the exploded view in four directions to facilitate understanding, and the planar decomposer optimizer 350 displays the planar decomposer 630 within the canvas 610 based on the size of the 3D object. Size can be optimized. More specifically, the planar decomposer optimization unit 350 may match the first center of the planar decomposer 630 disposed in the center canvas and the second center of the circle inscribed in the center canvas, and the canvas 610. The size of the planar decomposition body 630 can be enlarged by the diameter of the circle inscribed in the.

이 된다. For example, dividing a square having a length of 15 horizontally and vertically into 4 quadrants can generate 4 isosceles triangles with a height of 7.5, and each of the 4 isosceles triangles is a canvas 610 through which a planar decomposition body 630 will be output. ). In addition, each canvas 610 may be the same as the reflective surface area 650, which is an area where each planar decomposition body 630 is reflected. The diameter of the circle inscribed in an isosceles triangle with a width of 15 and a height of 7.5 is the maximum size of a planar decomposition body, and using the formula to find the radius inscribed to a right triangle, the radius R = (a + b-c) / 2 according to

Becomes

On the other hand, in the case of the general hologram implementation method (b), when a square having a length of 15 on one side is disassembled into four quadrants, the canvas 610 for having the flat disassembled body 630 of the same quadrant is The length of one side becomes 5, and thus the height of the planar decomposition body 630 is also 5.

7 is a view for explaining an embodiment of a trapezoidal canvas.

Referring to FIG. 7, when the hologram is implemented using a 3D object, the screen division optimization device 130 may provide a screen division function using a 3D viewer. 7 (a) and 7 (b) of FIG. 7 may correspond to the structures of the canvases 710, 730, and 750 on which the planar decomposers are disposed. In particular, the boundary between each canvas is implemented to form an angle of 45 degrees at each corner, and the left and right canvases 710 and 750 may be an isosceles triangle or a trapezoid.

In Figure (b), it can be seen that even if the planar decomposed body is enlarged within each of the canvases 710, 730, and 750 including the planar decomposed body, it is confirmed that it does not deviate from the canvas area. Therefore, in a hologram device including a polyhedron divided into three or four sides, it is possible to form a clean hologram without being disturbed by a side screen in a process in which the planar decomposed body is reflected on the reflective surface.

Figure (c) shows that a typical canvas is divided into rectangles without dividing it by 45 degrees when dividing the screen. The yellow area in Figure (c) corresponds to the reflective surface area 790, which is the area to be projected on the reflective surface, and in order to enlarge the hologram screen, rectangular canvases are superimposed on each other, and the plane decomposition can be output in the canvas. Since the area of the right canvas overlaps with the area of the center canvas, the hologram image of the right may overlap the hologram image of the center when it is implemented as an actual hologram.

8 is a diagram illustrating a process of generating a hologram object.

Referring to FIG. 8, the screen division optimization device 130 may generate a hologram target object by irradiating a 3D object in real time with a light source in at least three directions through the plane decomposition body generation unit 330. In Fig. (A), when the 3D object is a vessel, light effects reflected from the vessel surface can be reflected in the plane decomposer by irradiating light in each direction with respect to each surface. As a result, the screen division optimization device 130 may provide the generated hologram with realism like a real bowl.

In Figure (b), the screen division optimization device 130 may generate planar decomposers on the canvas by applying inversion effects on the screen and text through the flat decomposer generator 330, and the hologram object generator ( Through 370), a hologram target object may be generated based on the inverted image. In particular, the planar decomposer generation unit 330 may operate so that the hologram formed by reflecting on the reflective surface is normally output by applying an inversion effect to all planar decomposers formed on each canvas.

That is, the planar decomposed body generating unit 330 is generally inverted in the process of generating a planar decomposed body in order to prevent the screen from being flipped and awkward when an object is reflected through a reflective surface such as a mirror. Normal holograms can be viewed.

9 is a view for explaining a process of generating a hologram using a hologram object.

Referring to FIG. 9, the screen division optimization device 130 may generate a screen including the hologram target object 910 and output it to the reflective surface 930 through the flat display panel 950. The hologram image implemented through the flat display panel 950 is reflected at 45 degrees by each reflective surface 930 to form a hologram for the 3D object at a position perpendicular to the display panel of the screen division optimization device 130. You can.

In particular, the screen division optimization device 130 may generate a plurality of canvases in order to maximize space utilization in the process of generating the hologram target object 910 corresponding to the image reflected on the reflective surface 930.

In addition, the hologram using 3D data can be represented as before, after, left, and right by using the 3D viewer function on a 3D object, but there is a problem in that the screen is excessively wasteful when implemented as a hologram since the generally viewed screen is a square. The screen division optimization device 130 may provide a function of a 3D viewer capable of maximizing space utilization through a method of generating a planar decomposition object in each canvas based on at least three directions and arranging them in a developed view manner.

10 is a view for explaining a general hologram screen of a floating method and a hologram screen according to the present invention.

Referring to FIG. 10, in the case of a general hologram method in a screen configuration, the canvas 1030 to be projected as a hologram is formed in a rectangular shape (including a square) inscribed to a reflective surface formed by a triangle, thereby being a reflection surface that is an area reflected by the actual reflective surface. In the area 1010, there may be many areas that are wasted in addition to the hologram object 1050. For example, if the height is increased, there may be a problem that the left and right spaces are excessive, and when the width is increased, the space for the height portion is severe.

On the other hand, in the method according to the present invention, since the canvas 1030 and the reflective surface area 1010 are the same, a wasted area may not exist. Accordingly, the present invention can realize a hologram maximized at the same hologram device size.

11 is a diagram illustrating a screen configuration of a hologram generated by the screen division optimization device in FIG. 1 and a device implemented as a hologram.

Referring to FIG. 11, the screen division optimization device 130 may be applied to a hologram device that generates a hologram. The screen division optimization device 130 may generate the hologram target object 1130 based on the planar decomposition body and output the hologram object 1130 through the flat display panel 1110. The hologram object 1130 may be reflected through the reflective surface 1150 to form the hologram 1170. The screen division optimization device 130 may generate a hologram target object output from the hologram device composed of three surfaces, but is not limited thereto, and the hologram object output from the hologram device composed of four reflective surfaces as illustrated in FIG. 11. You can also create objects.

The screen division optimization device 130 may generate the hologram target object 1130 in various forms, and when the screen to be implemented is a square pyramid shape as illustrated in (a), all of the screen areas may be formed only in a triangle shape. In addition, if the screen to be implemented is a trapezoidal pyramid, as shown in Fig. (B), all screen areas can be formed in a trapezoidal shape. In the case of using the entire rectangular display as a screen, as shown in Fig. (C), some are triangular screens. The region and a portion may be formed of a combination of trapezoidal screen regions.

The screen division optimization device 130 may generate a hologram target object 1130 suitable for the hologram device to be implemented. The hologram device may be implemented by including a flat display panel 1110 and a reflective surface 1150. Meanwhile, the flat display panel 1110 may be implemented by being included in the screen division optimization device 130, and output the hologram target object 1130 generated by the screen division optimization device 130 to turn the reflective surface 1150. Through this, the holographic image of the 3D object can be reflected. A part of the reflected hologram image may be reflected by the reflective surface 1150 and the rest may pass through the reflective surface 1150, and the hologram 1170 may be formed inside the hologram device by the reflected image.

12 is a view for explaining a process of arranging planar decomposers based on the center of the 3D object.

Referring to FIG. 12, the left figure of Fig. (A) corresponds to a drawing showing the center and size of an object when viewed from the front, and the right figure shows the center and size of the object when looking at the 3D object from above. Corresponds to the drawings shown.

The screen division optimization device 130 may place a central plane decomposition body on the central canvas through the plane decomposition body optimization unit 350, and the box area 1210 including the 3D object as the entire object area You can set it, grab it, and set its center as the center of the object.

In Figure (b), the planar decomposer optimizer 350 matches the center of the central planar decomposer 1235 and the center of a circle inscribed in the central canvas 1215 to match the central planar decomposer 1235 to the central canvas. (1215). In addition, the planar decomposer optimization unit 350 may arrange the left and right planar decomposers 1231 and 1233 on the left and right canvases 1211 and 1213, respectively, to correspond to the central planar decomposer 1235. .

13 is a view for explaining a process of optimizing the size of the planar decomposition body.

Referring to FIG. 13, the screen division optimizing device 130 may optimize the sizes of the planar decomposers disposed on each canvas through the planar decomposer optimizer 350. In Figure (a), the planar decomposer optimizer 350 may move the center of the decomposer of the center plane down a certain distance when the horizontal length of the 3D object is greater than a certain percentage by the vertical length, and the center plane Based on the center of the decomposition body, the size of the center plane decomposition body can be enlarged in the direction of the left and right borders of the center canvas.

In general, when the center of the circle inscribed with the center canvas is matched with the center of the object, if the horizontal length is larger than the vertical length as shown in the left side of the figure (a), the generated hologram is too small or the left and right ends. Parts may be cut off. Therefore, if the difference between the length of the horizontal and the vertical is large, moving the center of the object down may generate an enlarged hologram. The reason is that the shape of the canvas, which is the area to be projected as a hologram, is a trapezoid (including a triangle) that becomes larger and smaller as it goes upward, so moving the central axis downward can make the widths on both sides larger.

In Figure (b), the planar decomposer optimizer 350 may move the center of the central planar decomposer by a specific distance upward when the vertical length of the 3D object is greater than the horizontal length, and the center of the central decomposer As a reference, the size of the central planar decomposer can be enlarged in the direction of the upper and lower borders of the central canvas. At this time, the planar decomposer optimization unit 350 may simultaneously adjust the position and size of the left and right planar decomposers to correspond to the central planar decomposer.

In general, when the center of the circle inscribed with the center canvas is matched with the center of the object, the advantage of being marked in the hologram is shown by rotating the plane decomposition inside the canvas in any direction by 360 degrees as shown in the left side of Figure (b). However, it can be seen that the free space still exists. If you move the center of the planar explode upward and zoom in as shown in the right side of Figure (b), you can have a larger hologram image. In this case, if the rotation of the hologram object is only rotated sideways around the center axis, There is an advantage in that the hologram image is largely obtained when a part of the object that is not displayed because it is rotated 360 degrees can be ignored.

14 is a view for explaining a process of aligning the horizontal central axis of the left and right planar decomposition bodies when the canvas is composed of three sides.

Referring to FIG. 14, the screen division optimization device 130 may obtain a larger hologram image by adjusting the positions of the left and right planar decomposers arranged on the left and right canvases through the planar decomposer optimizer 350.

In the figure (a) of FIG. 14, the planar decomposer optimization unit 350 raises the centers of the left and right planar decomposers 1410 and 1430 by 45 degrees from the left and right edges of the center canvas, respectively, to the horizontal axis. Therefore, when the center of the left and right canvases is grasped and the center of the planar decomposition body in the left and right canvases is grasped, the left and right regions of the actual hologram may not be displayed because the planar decomposers in the left and right canvases have many portions outside the actual display area.

In Figure 14 (b), it can be seen that the left and right canvases of the canvas disassembled into three sides are not symmetrical and one side is large and the other is small. That is, in order to obtain a hologram image as large as possible, it is better to secure a lot of canvas space. Thus, the planar decomposition body optimization unit 350 moves the horizontal center axes 1450 of the left and right plane decomposition bodies 1410 and 1430 down a predetermined distance so that the left and right regions of the actual hologram are not displayed. Problems can be minimized.

The screen division optimization device 130 may set and use the moving distances of the left and right planar decomposition bodies 1410 and 1430 in advance in consideration of the size of the hologram target object. Therefore, when comparing pictures (a) and (b), it can be seen that picture (b) has a larger hologram image than picture (a). This is because the regular display has a long rectangular shape, so when creating a trapezoidal canvas from a rectangular panel and creating a flat decomposition that is optimized for the canvas, the flat decomposition will minimize the area where the holographic image is cut out of the canvas or display panel area. You can.
