Hereinafter, embodiments for carrying out the invention will be described with reference to the drawings. In the figure, the same or equivalent parts are designated by the same reference numerals.

The image output system 1 of the present embodiment is a system that outputs an image (still image, moving image, or both) to the Ferris wheel. FIG. 1 is a block diagram of the image output system 1. The image output system 1 includes a control device 10 and a Ferris wheel 20.

The control device 10 is a device for controlling the image output of the Ferris wheel 20. The control device 10 is arranged in the command room and operated by the operator. The command room may be an office near the Ferris wheel 20 or an office in a remote location. The control device 10 transmits video information to the image output device 100 arranged in the Ferris wheel 20 via a network. The network is a communication network such as LAN (Local Area Network), WAN (Wide Area Network), telephone network (mobile telephone network, fixed telephone network, etc.), regional IP network, and the Internet. The network may be a wired network or a wireless network such as a wireless LAN. The control device 10 transmits image data to the image output device 100 of the Ferris wheel 20. The image data is image data to be displayed on the front or back of the Ferris wheel 20.

FIG. 2 is a front view of the Ferris wheel 20. The Ferris wheel 20 includes a rotating wheel 21 formed by combining a plurality of steel frames. The rotary wheel 21 is rotatably supported by the support legs 23. The rotating wheel 21 rotates at a speed set by an operator, a designer of the Ferris wheel 20, or the like. A plurality of gondola 22s are arranged on the outer circumference of the rotating wheel 21.

FIG. 3 is a partially enlarged view of the rotating wheel 21. In FIG. 3, the gondola 22 is removed from the rotary wheel 21 in order to make the configuration of the rotary wheel 21 easy to see. The rotary wheel 21 rotates at a constant speed around the rotation axis C clockwise in the drawing. The configuration (framework, etc.) of the rotating wheel 21 can be arbitrarily changed. The rotating wheel 21 of the present embodiment includes 30 sets of frames of R1 to R30 extending radially around the rotating shaft C. R1 to R30 each include steel frames 21a and 21b extending in a straight line from the outer circumference of the rotating wheel 21 toward the rotating shaft C.

Lamps are arranged on the steel frames 21a and 21b, respectively. Four lamps L1 to L4 are arranged on the steel frame 21a. Further, 22 lamps L5 to L26 are arranged on the steel frame 21b. These lamps are arranged in a row from the outer circumference toward the center C. In the case of the present embodiment, since the rotating wheel 21 has 30 sets of radial frames of R1 to R30, 780 (= 26 × 30) lamps are arranged on one surface of the rotating wheel 21. .. In the present embodiment, the back surface side of the rotating wheel 21 has the same configuration as that shown in FIGS. 2 and 3. Lamps L1 to L26 are also arranged on the steel frames 21a and 21b on the back side in the same manner as on the front side. It is up to the designer of the Ferris wheel 20 to decide which of the rotating wheels 21 is the front.

The lamps L1 to L26 of the present embodiment have substantially the same configuration. FIG. 4 shows the configuration of the lamp L1 as a representative of the lamps L1 to L26. The lamp L1 includes an elongated housing. In the housing, four light emitting bodies 24 are arranged in a row along the longitudinal direction of the lamp L1. Since 780 lamps are arranged on one surface of the rotating wheel 21, 3120 (= 4 × 780) light emitters 24 are arranged on one surface of the rotating wheel 21.

Each light emitter 24 includes an LED (Light Emitting Diode) element. Each light emitting body 24 emits light according to the control of the control unit 160 described later. One illuminant 24 corresponds to one pixel of the image. Red, green, and blue LEDs are arranged on one light emitter 24. Depending on the combination of these colors, each illuminant 24 emits various colors. A circuit for lightning surge may be arranged in each lamp. By arranging the lightning surge circuits distributed in each lamp, it is possible to reduce the destruction of the lamp due to a lightning strike.

Returning to FIG. 1, the Ferris wheel 20 includes an image output device 100. The image output device 100 is a device that displays an image transmitted from the control device 10 on the front surface or the back surface of the rotating wheel 21 by controlling the light emission of the light emitting body 24. The image output device 100 includes a front light emitting unit 110, a rear light emitting unit 120, a rotation sensor 130, a communication unit 140, a storage unit 150, and a control unit 160.

The front light emitting unit 110 is an image display device arranged in front of the rotating wheel 21. FIG. 5 is a diagram showing the configuration of the front light emitting unit 110. The front light emitting unit 110 includes control panels 111 to 114 and a plurality of sets of lamps L1 to L26.

The control panels 111 to 114 are devices for controlling the light emission of the light emitting body 24 included in each of the lamps L1 to L26. The control panels 111 to 114 are installed near the rotation axis C of the rotation wheel 21. The control panels 111 to 114 are connected to the control unit 160, respectively. Further, a plurality of sets of lamps L1 to L26 are connected to the control panels 111 to 114, respectively. Eight sets of lamps L1 to L26 of R1 to R8 are connected to the control panel 111, eight sets of lamps L1 to L26 of R9 to R16 are connected to the control panel 112, and R17 is connected to the control panel 113. Eight sets of lamps L1 to L26 of ~ R24 are connected. Further, six sets of lamps L1 to L26 of R25 to R30 are connected to the control panel 114. As described above, the lamps L1 to L26 are arranged on the rotating wheel 21. Each of the lamps L1 to L26 includes a plurality of light emitters 24. The control panels 111 to 114 control the light emitting body 24 based on the signal received from the control unit 160.

The rear light emitting unit 120 is an image display device arranged on the back surface of the rotating wheel 21. Since the configuration of the rear light emitting unit 120 is the same as that of the front light emitting unit 110, the description thereof will be omitted. In the present embodiment, the front light emitting unit 110 and the rear light emitting unit 120 are described as being a part of the image output device 100, but the external configuration of the image output device 100 (for example, one of the rotating wheels 21). It can also be regarded as a department).

Returning to FIG. 1, the rotation sensor 130 is a sensor that detects the rotation of the rotating wheel 21. The rotation sensor 130 is installed on the rotation shaft C of the rotation wheel 21, for example, and outputs a rotation detection signal to the control unit 160 every time the rotation wheel 21 rotates by a constant angle. The rotation detection signal may be a High / Low electric signal. In the present embodiment, as an example, the rotation sensor 130 outputs a rotation detection signal to the control unit 160 every time the rotation wheel 21 rotates by 0.1 °. The control unit 160 determines the rotational position of the rotary wheel 21 based on the signal from the rotary sensor 130.

The rotation position determined by the control unit 160 is, for example, the rotation angle of the rotation wheel 21 from the state where the rotation wheel 21 is in the home position H. In the present embodiment, as an example, the rotation position determined by the control unit 160 is assumed to be a rotation angle in units of 0.1 °. That is, the rotation position determined by the control unit 160 is a rotation angle of every 0.1 ° from 0 ° to 359.9 °. It is up to the designer to decide which rotation position is the home position H. In the present embodiment, as an example, the home position H is assumed to be the rotational position of the rotating wheel 21 when the steel frame 21a of the frame R1 is located at the top, as shown in FIG.

The communication unit 140 is a communication interface for connecting the image output device 100 to the network. The communication unit 140 may be a wired interface or a wireless interface such as a wireless LAN (Wireless Local Area Network). The communication unit 140 receives image data from the control device 10 via the network. The communication unit 140 stores the image data received from the control device 10 in the storage unit 150.

The storage unit 150 is a data readable / writable storage device such as a DRAM (Dynamic Random Access Memory), a SRAM (Static Random Access Memory), a flash memory, and a hard disk. The storage unit 150 functions as a storage means for the image output device 100. FIG. 6 is a diagram showing how various data are stored in the storage unit 150. Data such as image data 151 and mapping data 152 are stored in the storage unit 150.

The image data 151 is image data to be displayed on the front surface or the back surface of the rotating wheel 21. The image data 151 may be data received from the control device 10 via the network, or may be data stored in advance in the storage unit 150. The image data 151 may be still image data or moving image data. The image data may include both a still image and a moving image. The image data is, for example, AVI data in which one frame is composed of an image of 512 × 512 pixels. In the following description, the image data 151 is assumed to be a moving image of 30 frames / second as an example, and one frame thereof is assumed to be an image of 64 × 64 pixels as shown in FIG. The position of each pixel is represented by, for example, an XY coordinate value (X, Y) with the upper left of the image as the origin. The X-axis is the horizontal direction and the Y-axis is the vertical direction.

Returning to FIG. 6, the mapping data 152 is data in which the pixels of the image data 151 are assigned to each of the light emitting bodies 24. The mapping data 152 is composed of a plurality of mapping information. The mapping information is prepared for 360 °, and the information on the rotation position of the rotating wheel 21 is associated with each mapping information. Since the rotation sensor 130 of the present embodiment can detect the rotation position every 0.1 °, 3600 mapping informations are prepared every 0.1 °.

The mapping information will be described in detail with reference to FIGS. 8 (A) and 8 (B). FIG. 8A shows the lamps L1 to L26 arranged on the rotating wheel 21 in a state where the rotating wheel 21 is removed. 8 (B) shows the lamps L1 to L26 shown in FIG. 8 (A) superimposed on the image shown in FIG. 7 at a reduced scale. The states of the lamps L1 to L26 shown in FIGS. 8 (A) and 8 (B) are the states when the rotating wheel 21 is in the home position H, that is, when the rotating position of the rotating wheel 21 is 0 °. ..

As can be seen from FIG. 8B, the pixel at the position of the lamp L1 of R1 is (32.0). Therefore, the designer assigns position information (32.0) to the four light emitters 24 arranged in the lamp L1 of R1. The pixel at the position of the lamp L4 of R3 is (42,1). Therefore, the designer assigns the position information (42, 1) to the four light emitters 24 arranged in the lamp L4 of R3. In this way, the designer assigns position information to all 3120 light emitters 24 arranged on the rotating wheel 21. Then, the designer stores 3120 allocation information as mapping information 1 in the mapping data 152. The designer also assigns pixel position information to the light emitter 24 for other rotation positions (3599 rotation positions of 0.1 to 359.9 ° in the case of this embodiment) and maps them as mapping information 2 to 3600. Store in data 152. In the above description, the same position information is assigned to the four light emitting bodies 24 arranged in one lamp, but of course, different position information may be assigned to the four light emitting bodies 24.

Returning to FIG. 1, the control unit 160 is a processing device such as a processor. The control unit 160 operates according to a program stored in a ROM (Read Only Memory), a RAM (Random Access Memory), or a storage unit 150 (not shown) to realize various operations including "image output processing" described later. To do. FIG. 9 is a functional block diagram of the control unit 160. The control unit 160 has functions as a rotation position determination unit 161, an image data acquisition unit 162, a mapping information acquisition unit 163, and a light emission control unit 164. The rotation position determination unit 161 functions as a rotation position determination means of the image output device 100, the image data acquisition unit 162 functions as an image data acquisition means of the image output device 100, and the mapping information acquisition unit 163 maps the image output device 100. It functions as an information acquisition means, and the light emission control unit 164 functions as a light emission control means of the image output device 100. Each functional block shown in FIG. 9 may be a software block or a hardware block.

Next, the operation of the image output device 100 having such a configuration will be described.

When the control unit 160 of the image output device 100 receives an image output command from the control device 10 via the network, the control unit 160 starts the image output process. The image output process will be described below with reference to the flowchart of FIG.

The mapping information acquisition unit 163 acquires the mapping data 152 from the storage unit 150 (step S101). The mapping data 152 stores mapping information (mapping information 1-3600 shown in FIG. 6) for every 0.1 ° for 360 °.

Next, the image data acquisition unit 162 acquires the image data 151 from the storage unit 150 (step S102). As described above, in the case of the present embodiment, the image data 151 is a moving image at 30 frames / second, and one frame is an image of 64 × 64 pixels as shown in FIG.

Next, the rotation position determination unit 161 determines the current rotation position of the rotation wheel 21 based on the signal from the rotation sensor 130 (step S103). The rotation position determined by the rotation position determination unit 161 is, for example, the rotation angle of the rotation wheel 21 from the home position H every 0.1 °. For example, the rotation position determination unit 161 determines the current rotation position of the rotation wheel 21 by using the following method.

First, the rotation position determination unit 161 internally prepares a cyclic variable that circulates in the range of 0 ° to 359.9 °. As described above, the rotation sensor 130 is configured to output a signal each time the rotating wheel 21 rotates by 0.1 °. When the rotation position determination unit 161 receives a signal from the rotation sensor 130, the rotation position determination unit 161 counts up the circulation variable by 0.1 °. The rotation position determination unit 161 determines the value of the cyclic variable as the current rotation position of the rotation wheel 21. The method shown here is just an example. The rotation position determination unit 161 can determine the current rotation position of the rotary wheel 21 by using various methods.

Next, the light emission control unit 164 selects the mapping information corresponding to the current rotation position from the plurality of mapping information (step S104). For example, if the current rotation position of the rotating wheel 21 is at the home position H (that is, the position at 0 °), the mapping information 1 is selected from the mapping information 1 to 3600 shown in FIG.

Subsequently, the light emission control unit 164 controls light emission of 3120 light emitting bodies 24 arranged in front of the rotating wheel 21 based on the image data 151 (step S105). At this time, the light emission control unit 164 controls the light emitting body 24 based on the mapping information selected in step S104. For example, if the current rotation position of the rotating wheel 21 is at the home position H, the light emitting control unit 164 controls the light emitting body 24 as shown below.

First, the light emission control unit 164 specifies the positions of the corresponding pixels for each of the plurality of light emitting bodies 24 based on the mapping information 1. For example, in the case of the four light emitters 24 arranged in the lamp L1 of R1, as shown in FIG. 8 (B), the pixel at the position (32.0) is specified as the corresponding pixel. The light emission control unit 164 specifies the positions of the corresponding pixels for all 3120 light emitting bodies 24. Then, the light emission control unit 164 specifies the pixel value of the corresponding pixel for all 3120 light emitting bodies 24 based on the image data 151. The light emission control unit 164 causes the light emitting body 24 to emit light based on the specified pixel value. The light emission control unit 164 controls the light emission of the light emitting body 24 using the same mapping information until the rotating wheel 21 rotates by a constant angle (for example, 0.1 °).

FIG. 11A shows the lamps L1 to L26 in the home position H overlaid with the image shown in FIG. 7, and FIG. 11B shows the mapping information 1 and the image data of FIG. Based on this, it is a figure which shows the state which made the lamps L1 to L26 of the state of FIG. 11A emit light. The light emission control unit 164 also controls light emission of the light emitting body 24 on the back surface in the same manner as the light emitting body on the front surface.

Subsequently, the rotation position determination unit 161 determines whether the rotation wheel 21 has rotated by a constant angle (for example, 0.1 °) (step S106). Whether or not the rotation is performed by a certain angle (for example, 0.1 °) may be determined based on the rotation detection signal from the rotation sensor 130. When the rotating wheel 21 is not rotated by a constant angle (step S106: No), the rotation position determination unit 161 returns the process to step S105.

When the rotating wheel 21 is rotated by a constant angle (step S106: Yes), the rotating position determining unit 161 determines the current rotating position of the rotating wheel 21. Then, the light emission control unit 164 switches the mapping information used for light emission control to the mapping information corresponding to the current rotation position (step S107). For example, if the rotating wheel 21 is rotated by 0.1 ° from the home position H, the light emission control unit 164 switches the mapping information used for light emission control to the mapping information 2 shown in FIG. If the rotating wheel 21 is further rotated by 0.1 ° from the rotation position of 0.1 °, the light emission control unit 164 switches the mapping information used for light emission control to the mapping information 3.

When the switching of the mapping information is completed, the light emission control unit 164 returns to step S105 and executes the light emission control of the light emitting body 24 again using the switched mapping information. FIG. 12A is a superimposition of the image of FIG. 7 on the lamps L1 to L26 in a state of being rotated clockwise by an angle θ from the home position H. Further, FIG. 12B is a diagram showing a state in which the lamps L1 to L26 in the state of FIG. 12A are made to emit light based on the mapping information and the image data of FIG. 7. After that, the control unit 160 repeats steps S105 to S107 until a new command is received from the control device 10.

According to the present embodiment, the image output device 100 stores mapping information for one rotation of the rotary wheel 21 for each constant rotation angle, and the rotary wheel 21 rotates by a constant angle (for example, 0.1 °). Each time, the mapping information used for light emission control is switched to the mapping information corresponding to the current rotation position. Therefore, when the image output device 100 outputs the image to the rotating wheel 21, the image output device 100 simply identifies the pixel corresponding to the pixel corresponding to the light emitting body 24 from the mapping information, and the light emitting body 24 is based on the value of the corresponding pixel. It is only necessary to control the light emission. That is, in outputting the image to the rotating wheel 21, the image output device 100 does not need to perform complicated image processing such as rotating the image in the reverse direction in accordance with the rotation of the rotating wheel 21. As a result, the processing load of the image output device 100 is reduced, so that it is not necessary to take measures such as providing a high-performance processor. Further, since the processing becomes easy, the development cost of the image output device 100 is also reduced. Therefore, the user can display the image on the Ferris wheel 20 at low cost. Further, since the processing load is reduced, the moving image displayed on the rotating wheel 21 is smooth.

The size and skeleton of the rotating wheel differ depending on the Ferris wheel. Therefore, of course, the arrangement of the light emitters is different for each Ferris wheel. In the case of the method of Patent Document 1, in order to output the video to the Ferris wheel, it is necessary to purposely create the dedicated video information for each Ferris wheel. However, the image output device 100 of the present embodiment can display an image on the rotating wheel 21 only by recreating the mapping information while keeping the image data as it is, even if the arrangement of the light emitting body 24 is changed. The user does not have to bother to create dedicated image data for one Ferris wheel. Therefore, the user can display the image on the Ferris wheel 20 at low cost.

Even when the control device 10 controls the image output of the plurality of Ferris wheels 20, the mapping information can absorb the difference in the arrangement of the light emitters, so that the image data of the same format can be used in common for the plurality of Ferris wheels 20. By using the image output device 100 of the present embodiment, the cost of image creation is also reduced.

Further, the plurality of light emitters 24 for displaying an image are dispersedly arranged in the plurality of lamps L1 to L26, and each of the plurality of lamps L1 to L26 is for a lightning surge that protects the light emitter 24 from lightning strikes. Circuit is arranged. By arranging the lightning surge circuits distributed in each lamp, it is possible to reduce the destruction of the lamp due to a lightning strike.

The above embodiment is an example, and various modifications and applications are possible.

For example, in the above-described embodiment, the rotation sensor 130 detects the rotation of the rotating wheel 21 every 0.1 °, but the rotation detection interval does not necessarily have to be every 0.1 °. The detection interval may be an angle larger than 0.1 ° or a small angle. Further, the unit for determining the rotation position of the rotation position determination unit 161 does not necessarily have to be in units of 0.1 °. The timing at which the light emission control unit 164 switches the mapping information does not have to be every 0.1 °.

Further, in the above-described embodiment, the storage unit 150 stores the mapping information for one rotation of the rotating wheel 21, but the mapping information stored in the storage unit 150 is larger than the mapping information for one rotation of the rotating wheel 21.
