  2. Description of the Related Art Conventionally, an apparatus that displays an image such as characters using a light emitter such as an LED has been proposed. As such a thing, for example, an eaves signboard that can further attract the attention of a passerby by a moving display of an LED dot matrix display has been proposed (see Patent Document 1). This eaves signboard displays an arbitrary character or graphic on the LED dot matrix display or displays a flow character. Thus, an image can be displayed using a plurality of LEDs.

  However, this eaves signboard is sized to be installed at the eaves of a store and is provided with a horizontally long LED dot matrix display, and special processing is performed on the image displayed on the LED dot matrix display. Not done. For this reason, for example, when the LED dot matrix display is viewed from the left side, and there is a difference in the depth direction between the left and right edges, the image near the left edge is easy to see, but the image near the right edge is difficult to see, and the image is deformed. There is a problem of being visible.

  An embodiment of the present invention will be described below with reference to the drawings.

FIG. 1 is a perspective view showing an external configuration of the image processing light emission control system 1.
As shown in the figure, the image processing light emission control system 1 is configured such that a management terminal 2 and a light emission effect device 3 are communicably connected.

  The light emitting effect device 3 has a huge staircase shape with a height of 35 m, a total length of 70 m, and a number of steps of 171 in the present embodiment, and a plurality of light emitters 33 ( 33AA-33JG) are regularly arranged vertically and horizontally. In other words, the plurality of light emitters 33 are arranged at equal intervals in a horizontal row for each step of the staircase, and the plurality of light emitters 33 are arranged vertically and horizontally by multi-step staircases that are substantially equally spaced in the vertical direction. Yes. The plurality of light emitters 33 are arranged in a straight line in both the horizontal direction and the vertical direction. In addition, although each step of the stairs is equally spaced in the vertical direction, there is a landing area where the depth becomes wider for every certain number of steps.

  In this embodiment, each stair is slightly curved so that the center is concave when viewed from above (the curve is omitted in the figure). Along the curved surface, the light emitters 33 are arranged at a predetermined pitch (for example, 125 mm pitch) and aligned in a predetermined number (for example, 118) in a line. Since the height of the staircase is a predetermined height (for example, 175 mm), the interval between the light emitters 33 in the vertical direction is a predetermined height (for example, a pitch of 175 mm). Thus, the ratio of the vertical arrangement interval and the horizontal arrangement interval of the light emitters 33 can be an appropriate ratio (for example, horizontal 5 to vertical 7) instead of 1: 1.

  In this embodiment, the light emitting effect device 3 is formed in a huge staircase shape. However, the present invention is not limited to this, and various shapes such as a staircase having a different size, number of steps or shape, or a shape other than the staircase are used. It can be. For example, the light emitting effect device 3 can be formed by arranging a plurality of light emitters 33 vertically and horizontally on one surface of a tall building. In this case, since the person looks up at the building from below, the distance in the depth direction from the viewpoint of the person changes greatly between the high position and low position of the building. In addition, the illuminant on the surface of various objects such as the radial arm surface (circular surface) of the Ferris wheel, the outer wall of the building, the side of the bridge, the road surface, the outer wall of the building, the inner wall of the concert hall, the inner wall of the lobby 33 can be provided as the light emitting effect device 3.

FIG. 2 is a block diagram showing the configuration of the management terminal 2 and the light emitting effect device 3 constituting the image processing light emission control system 1.
The management terminal 2 includes an input operation unit 11 such as a keyboard and a mouse that receives operation inputs, a medium processing unit 12 that reads / writes data from / to a recording medium such as a CD-ROM, DVD-ROM, or USB, a liquid crystal display, or a CRT display.

In the storage unit 17, an editing program 21 (light emission display image processing program), a reproduction program 22, and various image data 23 are stored.

  The light emitting effect device 3 includes a central control unit 31 (light emission control means) that centrally controls the emission color and brightness of the plurality of light emitters 33, a light emitter 33 (33AA, 33BA,. In addition, an individual control unit 35 (35AA, 35BA,...) That controls the light emission of the light emitter 33 in accordance with the light emission control signal corresponding to its own address among the light emission control signals transmitted by addressing from the centralized control unit 31. I have.

  With this configuration, the centralized control unit 31 of the light emitting effect device 3 can send an individual light emission control signal to each individual control unit 35 by specifying an address, and the individual control unit that has received this light emission control signal The light emitter 33 connected to itself 35 can emit light according to the designated light emission control signal. This light emission control can be collectively managed by the central control unit 31, and an image can be displayed by the plurality of light emitters 33.

  FIG. 3 is a functional block diagram of functions executed by the control unit 15 of the management terminal 2 using the various image data 23 in the storage unit 17 in accordance with the editing program 21 (see FIG. 2) and the reproduction program 22 (see FIG. 2). FIG. 4 is an explanatory diagram of various images.

<< Editing process >>
As shown in FIG. 3, the control unit 15 executes pre-preparation processing, original image processing, composition image processing, and composition processing described below according to the editing program 21 (see FIG. 2).

<Preparatory processing (first processing)>
First, the original image 74 (see FIG. 4D) is stored in the original image storage unit 41 as various image data 23 of the storage unit 17 (see FIG. 2), and the composition image 76 (see FIG. 4F). Is stored in the composition image storage unit 42. The original image 74 and the composition image 76 may be still images or moving images, and can be arbitrary images.

  The control unit 15 (see FIG. 2) uses the 3DCG creation unit 43 to create 3DCG data 71 (see FIG. 4A) that specifies the three-dimensional position of the light emitter 33 provided in the light emitting effect device 3. The 3DCG data 71 is obtained by three-dimensionally displaying a light emitter image 71a indicating the light emitter 33. The control unit 15 (see FIG. 2) stores the created 3DCG data 71 in the 3DCG storage unit 44 as a kind of various image data 23.

  The control unit 15 (see FIG. 2) uses the UV map creation unit 46 to create a UV map 72 (see FIG. 4B) in which the three-dimensional position of the light emitter 33 in the 3DCG data is associated with the two-dimensional map. And stored in the UV map storage unit 47. The UV map 72 is two-dimensional data in which the light emitter positions 72a (see FIG. 4B) indicating the positions of the light emitters 33 (see FIG. 2) are arranged vertically and horizontally. This UV map 72 can be appropriately arranged at the three-dimensional position of the light emitter 33 when an appropriate image is superimposed on the UV map 72.

  The control unit 15 (see FIG. 2) uses the light emission display image map creation unit 50 to create a light emission display image map 73 (see FIG. 4C) from the UV map 72. The light emission display image map 73 is a two-dimensional image map corresponding to the arrangement of the light emitters 33, and one light emission point 73 a is provided corresponding to one light emitter 33.

  Although the light emitting point 73a is displayed by one pixel in the drawing, when assigning an image to the light emitting display image map 73, a pixel group of a predetermined range including this one pixel (for example, a pixel group of 5 × 7 pixels). The pixel information of one pixel of the light emission point 73a is created from the pixel information (the emission color and luminance of each pixel). The pixel information of one pixel of the light emitting point 73a is obtained in accordance with a rule determined as appropriate, such as an average value of pixel information of each pixel of the corresponding pixel group, or the same pixel information as a pixel at a predetermined position such as the upper left or the center. Value.

  The control unit 15 (see FIG. 2) stores the created light emission display image map 73 in the light emission display image map storage unit 52. With the processing so far, the 3DCG data 71, the UV map 72, and the light emission display image map 73 are completed, and preparations are completed. If this preliminary preparation is performed for the first time, the created 3DCG data 71, the UV map 72, and the light-emitting effect device 3 (see FIG. 1) and the arrangement of the light emitter 33 (see FIG. 1) will be changed. The light emission display image map 73 can be used repeatedly.

<Original image processing>
The control unit 15 (see FIG. 2) that performs the original image processing reads the original image 74 (see FIG. 4D) from the original image storage unit 41, and is provided in the light emission effect device 3 by the original image deformation unit 49. The original image 74 is deformed in accordance with the deformation information determined by the arrangement of the light emitters 33, and a deformed image 75 (see FIG. 4E) is created as a light emitting display format deformed image. In the case of the light emitters 33 (see FIG. 1) arranged on the stairs as in this embodiment, a predetermined angle (for example, an arbitrary angle between 20 ° and 30 °) with the upper part of the vertically standing image facing forward. ) Deforms the perspective into an image that appears in the opposite direction to the staircase as if tilted. More specifically, the lower end of the original image 74 is fixed and the upper part (back side) is expanded in the horizontal and vertical directions, or the upper end of the original image 74 is fixed and the lower part (front side) is set in the horizontal and vertical directions. The process of reducing in the direction or both of the processes is executed to perform a deformation process for deforming the quadrangle into a substantially inverted trapezoid.

  In FIG. 4E, the deformed image 75 is an image in which the square image and the number image are combined for easy understanding. However, when actually used, there is no character such as a landscape photograph or illustration. It is preferable that the image be a background.

  The control unit 15 (see FIG. 2) reads the light emission display image map 73 (see FIG. 4C) from the light emission display image map storage unit 52, and produces a light emission display format modified image creation unit 51 (original image processing unit). Thus, the deformed image 75 (see FIG. 4E) created by the original image deforming unit 49 is superimposed on the light-emitting display image map 73 to create a light-emitting display format deformed image 81 (see FIG. 4I). The light emitting display format deformed image 81 is an image obtained by matching the deformed image 75 with the resolution of the light emitting display image map 73, and the appearance hardly changes from the deformed image 75.

  The control unit 15 (see FIG. 2) sends the created light emission display format deformed image 81 (see FIG. 4I) to the light emission display format image composition unit 54 (image composition unit).

<Image processing for composition>
The control unit 15 (see FIG. 2) that performs the composition image processing reads the composition image 76 (see FIG. 4F) from the composition image storage unit 42 and 3DCG data 71 (see FIG. 4 (FIG. 4)). A) (see A)) is read out, and the camera mapping execution unit 45 performs camera mapping on the 3DCG data 71 using the predetermined assumed viewpoint as a viewpoint and performs camera mapping on the 3DCG data 71 to obtain a camera mapping image 77a (see FIG. (See FIG. 4G). This camera mapping is arranged in the 3DCG data 71 so that the composition image 76 can be seen without deformation when viewed from the viewpoint. In the case of the huge staircase of the present embodiment, if the viewpoint is a position at a predetermined distance (for example, 18 m) at a normal person's eye level (for example, 1.6 m from the ground), the upper staircase is at the top of the landing, etc. A part of the light emitters 33 (see FIG. 1) is hidden in the lower stairs. The same pixel information as the light emission point 73a corresponding to the position where the light emission point 73a is hidden is assigned to the light emission point 73a (see FIG. 4C) corresponding to the light emitter 33 in the hidden portion. This prevents the upper light emitter 33 from partially emitting light.

  Note that the composition image 76 in FIG. 4F is the same as the original image 74 in FIG. 4D, but this is for ease of understanding of the deformation and the like for the sake of explanation. Different images are used for the image 76 and the original image 74.

  The control unit 15 (see FIG. 2) reads the UV map 72 (see FIG. 4B) from the UV map storage unit 47 and pastes it on the 3DCG data 71 by camera mapping by the synthesis UV map image creation unit 48. A composite UV map image 78 (see FIG. 4H) is created by extracting the UV map 72 from the camera mapping image 77a.

  In FIG. 4H, the compositing image 76 is an image in which the grid image and the number image are combined for easy understanding. However, when actually used, a character image and other transparent images are used. It is preferable to do. In addition, as shown in the overlapping portion 78a in the upper part of FIG. 4H, the overlapping portion 78a is generated in the composition UV map image 78 in the region where the hidden portion of the light emitter 33 is generated (in this embodiment, the upper portion of the staircase). For this reason, it is preferable that the characters displayed in the composite UV map image 78 be arranged in a lower region where the overlapping portion 78a is difficult to occur (a region where the light emitter 33 is not hidden on the front side).

  The control unit 15 (see FIG. 2) reads the light emission display image map 73 (see FIG. 4C) from the light emission display image map storage unit 52, and generates the light emission display format composition image creation unit 53 (composition image processing). ), The composition UV map image 78 (see FIG. 4H) is superimposed on the light emission display image map 73 (see FIG. 4C), and the light emission display format composition image 82 (see FIG. 4I). ). The light emission display format composition image 82 is an image obtained by matching the composition UV map image 78 with the resolution of the light emission display image map 73, and the appearance is almost the same as the composition UV map image 78. The light emitting display format composition image 82 has a character portion 82a (see FIG. 4I) and a transmissive portion 82b.

  The control unit 15 (see FIG. 2) sends the created light emission display format composition image 82 to the light emission display format image composition unit 54.

<Compositing process>
The control unit 15 (see FIG. 2) emits light on the light emitting display format deformed image 81 (see FIG. 4I) created by the light emitting display format deformed image creating unit 51 by the light emitting display format image synthesizing unit 54. The light emission display format composition image 82 (see FIG. 4I) created by the display format composition image creation unit 53 is superimposed and synthesized, and a composite image 83 (light emission display image) as shown in FIG. Data, luminous display format composite image).
The control unit 15 (see FIG. 2) stores the created composite image 83 in the composite image storage unit 55.

<< Playback process >>
Next, the control unit 15 (see FIG. 2) executes a reproduction process described below in accordance with the reproduction program 22.

<Reproduction processing>
The control unit 15 (see FIG. 2) reads the composite image 83 from the composite image storage unit 55, and the composite image output unit 56 displays the composite image 83 from the I / O interface unit 14 to the central control unit 31 of the light emitting effect device 3. Output. When the composite image 83 is a still image, the control unit 15 (see FIG. 2) continues to output the composite image 83 for a predetermined time or until the playback operation is stopped by the input operation unit 11, and the light emission effect device 3 (FIG. 1), the display continues. When the composite image 83 is a moving image, the control unit 15 (see FIG. 2) continues to reproduce and output the moving image, and causes the light emitter 33 of the light emitting effect device 3 to display a moving image.

  When the central control unit 31 (see FIG. 2) of the light emitting effect device 3 receives the composite image 83 (see FIG. 4 (I)), the individual control unit of the address corresponding to each pixel (light emission point 73a) of the composite image 83. 35 (see FIG. 2), the emission color and luminance data of each pixel are transmitted simultaneously, and the individual control units 35 cause the respective light emitters 33 to emit light simultaneously to the emission color and luminance of the addressed pixel. As a result, regardless of whether the composite image 83 is a still image or a moving image, light emission by the plurality of light emitters 33 can be collectively controlled by the central control unit 31 and displayed in real time in conjunction with each other.

With the image processing light emission control system 1 described above, even if the light emission effect device 3 has a plurality of light emitters 33 arranged on the surface of an object that has a change in the depth of the surface when viewed from the assumed viewpoint, a plurality of light emission that is linked. The body 33 can display the image in an easy-to-see manner.
Thereby, the illumination by the graphic image in the huge area where the depth is generated can be realized.

  In the light emission display image map 73, a pixel group having an aspect ratio corresponding to the aspect ratio of the light emitter 33 arranged in the light emitting effect device 3 is set to one light emission point 73a. The ratio can be easily maintained and a good image can be displayed on the light emitter 33.

  Further, since the emission color and luminance of one emission point 73a are determined based on the color information (for example, RGB color information) of the pixels in the pixel group assigned to the emission point 73a, A natural image with little difference between the image 75 and the composition image 76 can be displayed.

  Further, since a composite image 83 is generated by combining the light emission display format deformed image 81 created based on the UV map 72 and the light emission display format composition image 82 using camera mapping, it is possible to select which viewpoint using each feature. It is possible to prevent the image from collapsing too much when viewed from the top.

  That is, when a large image is displayed by arranging a large number of light emitters 33 in a large building as in the grand staircase of the above embodiment, the distance from the light emitter 33 is shifted in the horizontal direction from the center. Depending on the difference in angle, the perspective of each light-emitting body 33 varies greatly. And if you see a part that is not visible due to the shadow of the step when viewed from near, like a staircase, and if you see it well when viewed from a distance, the letter of the step will be visible from any position. It is difficult to display a natural background. Even in such a situation, the image processing light emission control system 1 can recognize characters and backgrounds to some extent satisfactorily from anywhere by using the composite image 83 obtained by combining the light emission display format deformation image 81 and the light emission display format composition image 82. As described above, an image can be displayed by the plurality of light emitters 33.

  Further, since the character portion 82a and the transparent portion 82b are provided in the light emitting display format composition image 82, the composition with the light emitting display format modified image 81 can be easily executed.

  Further, since the character portion 82a of the light emission display format composition image 82 is set in a region that is difficult to be seen even if the viewer's viewpoint moves (in this embodiment, the lower central region on the staircase surface), It is possible to prevent or suppress the occurrence of 78a and making it difficult to see.

  Further, since the original image 74 is deformed by the original image deforming unit 49 in accordance with the arrangement of the light emitters 33 provided in the light emitting effect device 3, even when a huge image is displayed on a huge structure, it is far away ( It is possible to prevent the back side) from becoming difficult to see and to make the image look good.

  Further, even if an object has an uneven surface and a part that is hidden depending on the viewpoint, the composite image 83 using the light-emitting display format deformed image 81 and the light-emitting display format compositing image 82 can be used from various viewpoints. An image that looks good can be displayed. In particular, with respect to camera mapping used for the light-emitting display format composition image 82, an image in which characters can be viewed well from any viewpoint by not arranging characters in an area where characters are viewed in duplicate. Can be displayed.

The present invention is not limited only to the configuration of the above-described embodiment, and many embodiments can be obtained.
For example, in the case of the above-described staircase, the inclination angle at which the original image deformation unit 49 performs the deformation for inclining the upper part of the vertical image to the near side can be set to another angle. Here, FIG. 5A to FIG. 5F are photographs in which the illuminant 33 displays the deformed image 75 when the tilt angle is variously changed and the light emitting display format deformed image 81 created from the deformed image 75. Is shown. The tilt angles for tilting the upper part forward from each vertical plane and the visibility when viewed from various viewpoints are as follows.

FIG. 5A: Inclination angle = 0 °, visibility = Δ
FIG. 5 (B): Inclination angle = 10 °, visibility = ◯
FIG. 5C: Inclination angle = 20 °, visibility = ◎
FIG. 5D: Inclination angle = 30 °, visibility = ◎
FIG. 5E: Inclination angle = 40 °, visibility = Δ
FIG. 5F: Inclination angle = 50 °, visibility = ×
* ◎ = Good, ○ = Available, Δ = Slightly inferior, × = Not preferable.

  Thus, when arrange | positioning the light-emitting body 33 on the object on a staircase, an inclination angle can be 0 degree-40 degrees, 10 degrees-30 degrees are preferable, and 20 degrees-30 degrees are suitable.

Further, not only the staircase shape but also the light emitter 33 can be arranged on an object of various shapes as shown in FIGS. 5 (G) to 5 (H).
FIG. 5G is an explanatory diagram when the light emitting effect device 3 is configured by arranging the light emitter 33 on the surface of the sphere. In this case, the 3DCG data 71A of the sphere is created, the UV map 72A of the sphere surface is created therefrom, and the other operations may be executed by the editing program 21 (see FIG. 2) described in conjunction with FIG. In the original image deformation unit 49, for example, with the assumed viewpoint as the front center, the sphere surrounding part seen from the assumed viewpoint is enlarged, the sphere center part seen from the assumed viewpoint is reduced, or both By performing the above, visibility can be improved even if the light emitter 33 is arranged on a huge sphere and an image is displayed.

  FIG. 5H is an explanatory diagram when the light-emitting effect device 3 is configured by arranging the light-emitting body 33 on the barrel-shaped body surface. In this case, the 3DCG data 71B of the barrel-shaped body is created, the UV map 72B of the barrel-shaped body surface is created therefrom, and the other operations may be executed by the editing program 21 described with reference to FIG. In the original image deformation unit 49 (see FIG. 2), for example, assuming that the assumed viewpoint is slightly above the front center (the viewpoint of the 3DCG data 71B in FIG. 5 (H)), the lower front part of the barrel shape viewed from the assumed viewpoint is greatly enlarged. The left and right sides of the barrel mold and the upper part of the upper surface of the barrel mold are deformed to a certain extent, the upper front part of the barrel mold and the front front part of the barrel mold are deformed, or both are deformed. Therefore, even if the light emitter 33 is arranged in a huge barrel-shaped body and displayed as an image, the visibility can be improved.

  Further, the light emitting effect device 3 is not limited to one object, and can be a plurality of objects. For example, an object such as a sphere described in FIG. 5G or a barrel-shaped object described in FIG. 5H is installed in front of the stepped object described in the first embodiment, and a plurality of objects are provided on each object. The light emitters 33 (see FIG. 1) may be arranged, and all the light emitters 33 may be collectively controlled in synchronization by one central control unit 31 (see FIG. 2) or the central control unit 31 for each object. In this case, foreground objects such as a sphere or a barrel shaped object present in the foreground and a background object such as a staircase arranged behind the foreground object are displayed so as to be projected by camera mapping. Display with the illuminant 33 as if no object is present, display different images for the foreground object and the background object with the illuminant 33, and highlight the difference between the images displayed in the foreground object and the background object, or It is possible to produce effects rich in variations, such as performing effects by switching between both displays as appropriate.

  When displaying different images for the foreground object and the background object, for example, texture mapping or camera mapping for the foreground object or a composite image thereof, and texture mapping for the background object, etc. Can do. Thereby, an effect with good visibility can be performed.

  In the above embodiments, the vertical direction and the horizontal direction have been described as vertical and horizontal. However, the present invention is not limited to this, and when an object is curved in plan view, the horizontal direction that curves along the curved surface is defined as horizontal. When the object is curved in side view, the vertical and horizontal centers that are curved along the curved surface are vertical or inclined if the object is a quadrangular object that is inclined. The direction of the line (the horizontal center line that bisects the quadrangle substantially in the vertical direction and the vertical center line that bisects the quadrangle substantially in the horizontal direction) can be set appropriately, such as vertical and horizontal. As a result, it is possible to display a good image by arranging the light emitters 33 in a substantially grid pattern for objects of various shapes.
