[0010] Hereinafter, embodiments of the present disclosure will be described with reference to the drawings. In this disclosure, the drawings relate to one or more embodiments. In all drawings, similar components are designated by similar reference numerals, and descriptions thereof will be omitted as appropriate.

[0011] <<First embodiment>> <Summary> The information processing device of the first embodiment has a feature of projecting a guide image showing instructions given to (directed at) the performer (the instructions that the performer must follow) onto the performance area (floor) where the performer is performing. The configuration of the information processing device will be described in detail below.

[0012] <Overview of information processing system> First, an overview of an information processing system including an information processing device 10 will be described with reference to Fig. 1. The information processing system includes the information processing device 10 and a projection device 1. The information processing system may further include a performance area 2.

[0013] The performance area 2 is a floor surface. The performance area 2 may be a floor surface designed for an information processing system, or may be an existing floor surface. The performers 3 perform by standing on the performance area 2. Examples of the performance area 2 include, but are not limited to, a stage, a photography area in a photography studio, a practice floor, etc.

[0014] A projection sheet may be spread out over the performance area 2. The configuration of the projection sheet is not limited. For example, a widely used sheet for projecting images may be used as the projection sheet. A white sheet, carpet, or the like may also be used as the projection sheet. By spreading the projection sheet over the performance area 2, the various information projected by the projection device 1 is displayed more clearly in the performance area 2.

[0015] Furthermore, the performance area 2 may be provided with scale marks (not shown in FIG. 1) that serve as a guide for positioning within the performance area 2. However, the performance area 2 does not have to be provided with scale marks 5. For example, the performance area 2 may be provided with a pattern in which multiple scale marks 5 are regularly arranged, as shown in FIG. 2. The scale marks 5 in FIG. 2 are cross marks, but the scale marks 5 are not limited to this. An example of the interval at which the scale marks 5 are arranged is 1 meter, but this is not limiting. If such scale marks 5 are provided in the performance area 2, it is preferable because it makes it easier to align the projection screen 7 projected by the projection device 1. Furthermore, it is preferable because the scale marks 5 can be used as instructions and landmarks for the performers' standing positions and movement lines.

[0016] There are various ways to generate a performance area 2 showing the scale marks 5, and there are no particular limitations. For example, a performance area 2 showing the scale marks 5 may be generated by spreading a sheet with the scale marks 5 displayed (e.g., printed) over the performance area 2. Alternatively, a sticker with the scale marks 5 may be attached to the projection sheet, or the scale marks 5 may be drawn on the projection sheet with pen or ink, etc. The example shown here is merely an example, and is not limited to this example.

[0017] The projection device 1 projects a projection screen 7 onto the performance area 2. The aspect ratio of the projection screen 7 is, for example, 16:10 (= width: height), but is not limited to this. The projection size can be, for example, 514 inches to 617 inches, but is not limited to this. As shown in FIG. 3, the projection device 1 can have a certain range of lens shift movement in the vertical and horizontal directions. Note that the width of the movement range shown in the figure is merely an example and is not limited to this.

[0018] The projection device 1 is installed in a position and orientation that allows it to display a projection screen 7 in the performance area 2. For example, the projection device 1 may be attached to the ceiling or to another member that is located at a relatively high position.

[0019] When projecting the projection screen 7 onto the performance area 2 (floor) from a relatively high position such as the ceiling, the projection device 1 must have sufficient brightness to clearly display the guide information 4 on the performance area 2. For example, if the distance from the performance area 2 to the projection device 1 is between 6 m and 7 m, the brightness of the projection device 1 should be 18,000 lumens (lm) or more, and more preferably 19,000 lumens or more.

[0020] The inventor has confirmed that when the distance from the performance area 2 to the projection device 1 is between 6 m and 7 m, the guidance information 4 can be clearly displayed in the performance area 2 by satisfying the brightness conditions of the projection device 1. The inventor has also confirmed that when the distance from the performance area 2 to the projection device 1 is between 6 m and 7 m and the brightness of the projection device 1 is less than 18,000 lumens, the guidance information 4 cannot be clearly displayed in the performance area 2.

[0021] Returning to FIG. 1, the projection device 1 can receive a guide image from the information processing device 10 and display the received guide image on a projection screen 7 projected onto the performance area 2. The guide image projected onto the performance area 2 includes guide information 4 indicating instructions given to the performer 3. In the example of FIG. 1, the guide information 4 is a cross mark, and the display position of the mark indicates the position instructed for the performer 3 within the performance area 2. Note that the guide information 4 is not limited to a mark indicating the position within the performance area 2. Variations of the guide information 4 will be explained below.

[0022] The information processing device 10 is communicably connected to the projection device 1. The information processing device 10 inputs a guide image showing guidance information 4 to the projection device 1 and projects the input guide image. The information processing device 10 may be a general-purpose device such as a personal computer, a tablet terminal, a smartphone, or the like, or may be a dedicated device designed for an information processing system.

[0023] The information processing device 10 may include an input device and a display. An operator can operate the information processing device 10 to generate a guide image to be projected by the projection device 1, or to read a pre-stored guide image and display it on the display of the information processing device 10. Furthermore, the guide image projected onto the performance area 2 by the projection device 1 may be simultaneously displayed on the display of the information processing device 10. In this case, the operator can check the guide image projected onto the performance area 2 by looking at the display of the information processing device 10. The detailed configuration of the information processing device 10 will be described later.

[0024] Although not shown in Fig. 1, the information processing system may further include a motion capture system. The motion capture system is a system that digitizes (expresses as digital data) the movements of the performer 3. For example, an optical motion capture system can be used.

[0025] <Hardware configuration of information processing device 10> Next, an example of the hardware configuration of the information processing device 10 will be described. Each functional unit of the information processing device 10 is realized by any combination of hardware and software. Those skilled in the art will understand that there are various variations in the realization method and device. The software includes programs that are pre-loaded when the device is shipped, and programs downloaded from recording media such as CDs (Compact Discs) or servers on the Internet.

[0026] FIG. 4 is a block diagram illustrating an example of the hardware configuration of an information processing device 10. As shown in FIG. 4, the information processing device 10 has a processor 1A, a memory 2A, an input / output interface 3A, a peripheral circuit 4A, and a bus 5A. The peripheral circuit 4A includes various modules. The information processing device 10 does not necessarily have to have the peripheral circuit 4A. Note that the information processing device 10 may be composed of multiple devices that are physically and / or logically separated. In this case, each of the multiple devices can have the above hardware configuration.

[0027] The bus 5A is a data transmission path for the processor 1A, memory 2A, peripheral circuit 4A, and input / output interface 3A to mutually transmit and receive data. The processor 1A is, for example, a central processing unit (CPU) or a graphics processing unit (GPU). The memory 2A is, for example, a random access memory (RAM) or a read-only memory (ROM). The input / output interface 3A includes interfaces for acquiring information from input devices, external devices, external servers, external sensors, cameras, etc., and interfaces for outputting information to output devices, external devices, external servers, etc. The input / output interface 3A also includes an interface for connecting to a communication network such as the Internet. Examples of input devices include a keyboard, mouse, microphone, physical buttons, and touch panel. Examples of output devices include a display, projector, speaker, printer, and mailer. The processor 1A can issue commands to each module and perform calculations based on the results of those calculations.

[0028] <Functional configuration of information processing device 10> Next, a detailed description will be given of the functional configuration of the information processing device 10. Fig. 5 is an example of a functional block diagram of the information processing device 10. As shown in the figure, the information processing device 10 has an acquisition unit 11 and a projection control unit 12.

[0029] The acquisition unit 11 acquires a guide image to be projected onto the performance area 2 where the performer 3 performs.

[0030] The guide image includes guide information 4 indicating the instructions given to the performer 3. Examples of instructions given to the performer 3 include, but are not limited to, the position to stand in the performance area 2, the movement line within the performance area 2, the movement speed, the movements to be made at each position (jumping, crouching, falling, etc.), information about the performance, and information about the progress of the performance and filming. The guide information 4 can indicate the instructions given to the performer 3 using at least one of marks, figures, numbers, letters, symbols, pictures, still images, and moving images.

[0031] One guide image may include instructions for one performer 3, or may include instructions for multiple performers 3. The instructions for each of the multiple performers 3 included in one guide image may be displayed so that they can be distinguished from one another. There are various means for displaying the instructions for each of the multiple performers 3 so that they can be distinguished from one another, and one example is color-coding.

[0032] An example of the guidance information 4 will be described below, but the guidance information 4 is not limited to the following example.

[0033] For example, the guidance information 4 may include a position guidance mark. The position guidance mark indicates the standing position of the performer 3 within the performance area 2. As shown in FIG. 6, when a guidance image is projected onto the performance area 2, the position guidance mark (guidance information 4) is displayed at the standing position instructed to the performer 3 within the performance area 2.

[0034] Additionally, the guidance information 4 may include a movement guide line. The movement guide line indicates the movement line of the performer 3 within the performance area 2. As shown in FIG. 7, when a guide image is projected onto the performance area 2, the movement guide line (guidance information 4) is displayed along the movement line instructed to the performer 3 within the performance area 2. The movement guide line (guidance information 4) shown in FIG. 7 is an arrow line, and the direction of the arrow indicates the direction in which the performer 3 will move. The guidance information 4 shown in FIG. 7 also indicates the starting position (the position where "Start" is displayed in the figure) from which the performer 3 will begin the movement instructed.

[0035] Additionally, the guidance information 4 may include a movement guide mark. The movement guide mark indicates the movement line of the performer 3 within the performance area 2. As shown in FIG. 8, when a guide image is projected onto the performance area 2, the movement guide mark M (guidance information 4) moves along the movement line instructed to the performer 3 within the performance area 2. This movement allows the movement guide mark M to indicate the movement line instructed to the performer 3 within the performance area 2.

[0036] Furthermore, the movement guide mark M can move at a movement speed instructed to the performer 3. By moving at such a movement speed, the movement guide mark M can indicate the movement speed instructed to the performer 3.

[0037] The guidance information 4 shown in FIG. 8 also indicates the direction of movement instructed to the performer 3 by the direction of movement of the movement guide mark M. The guidance information 4 shown in FIG. 8 also indicates a line along the path of movement instructed to the performer 3. The movement guide mark M will move along this line. The guidance information 4 shown in FIG. 8 also indicates the starting position (the position where "Start" is displayed in the figure) from which the instructed movement of the performer 3 will begin.

[0038] Although not shown, the guide information 4 may display a scale image indicating length (distance). The scale image includes, for example, a straight line of a predetermined length and text information indicating the length of the straight line. The predetermined length may be 1 m, 3 m, 5 m, 10 m, etc., or may be any other length. By using such a scale image in combination with the scale marks 5 (see FIG. 2) present in the performance area 2, the performer 3 can accurately grasp the distance.

[0039] Next, a description will be given of a means for acquiring a guide image by the acquisition unit 11. The acquisition unit 11 can acquire a guide image by means of either of the following acquisition examples 1 and 2.

[0040] Acquisition example 1 In Acquisition Example 1, the acquisition unit 11 acquires a guide image by reading out a guide image that has been stored in advance in a predetermined storage device from the predetermined storage device. The predetermined storage device may be provided in the information processing device 10, or may be provided in an external device communicably connected to the information processing device 10. The same assumptions regarding the predetermined storage device apply hereinafter.

[0041] The acquisition unit 11 may read out, from a predetermined storage device, a guide image designated by the operator from among guide images stored in the predetermined storage device, in accordance with an operation by the operator.

[0042] Each guide image stored in a predetermined storage device may be associated with attribute information of the guide image. Then, the operator may perform an image search using the attribute information to search for a predetermined guide image from among multiple guide images stored in the predetermined storage device, and specify the searched guide image as the guide image to be projected onto the performance area 2. For example, the operator may input a certain attribute as an image search key into the information processing device 10. Then, the acquisition unit 11 may refer to the attribute information of each guide image, identify a guide image that includes the input key (attribute information), and present the identified guide image to the operator as a search result. The operator can specify a predetermined one from the guide images presented as the search result.

[0043] Examples of attribute information include, but are not limited to, identification information (such as name) of the person (performer 3) to whom instructions are conveyed in each guide image, identification information of the scene in which each guide image is displayed in the performance area 2, the type of instructions indicated by each guide image (standing position, movement route, etc.), and the pre-scheduled timing for using each guide image (such as 10:00-10:30 on September 11, 2024).

[0044] Alternatively, the acquisition unit 11 may read out a predetermined guide image from among the guide images stored in the predetermined storage device according to a predetermined rule. There are various rules. For example, a schedule for using each guide image may be determined in advance, and information indicating the contents of the schedule may be stored in the information processing device 10. The schedule indicates the guide image to be used at each timing, such as "September 11, 2024, 10:00 to 10:30: Guide image A." The acquisition unit 11 may refer to this schedule to identify the guide image to be used at the current time, and read out the identified guide image from the predetermined storage device.

[0045] Example 2 In acquisition example 2, the acquisition unit 11 acquires a guide image by generating the guide image in accordance with an operation by an operator. For example, the acquisition unit 11 can generate the guide image based on the operation of the operator by using software (application) for image generation installed in the information processing device 10.

[0046] Returning to FIG. 5, the projection control unit 12 causes the projection device 1, which projects the projection screen 7 onto the performance area 2, to project the guide image acquired by the acquisition unit 11. That is, the projection control unit 12 inputs the guide image acquired by the acquisition unit 11 into the projection device 1 and causes it to project. The projection device 1 is installed so as to project the projection screen 7 onto the performance area 2. The projection control unit 12 controls the projection device 1 to project the guide image onto the performance area 2.

[0047] Next, an example of the flow of processing by the information processing device 10 will be described using the flowchart in Fig. 9. Note that the purpose here is to explain the flow of processing. Details of each process have been described above, so explanations here will be omitted as appropriate.

[0048] In S10, the information processing device 10 acquires a guide image to be projected onto the performance area 2 where the performer 3 will perform. In S11, the information processing device 10 causes the projection device 1 to project the guide image onto the performance area 2.

[0049] In one example, the guide image includes a position guide mark (guide information 4). As shown in Figure 6, when the guide image is projected onto the performance area 2, the position guide mark (guide information 4) is displayed at the position instructed for the performer 3 within the performance area 2.

[0050] In another example, the guide image includes a movement guide line (guide information 4). As shown in Fig. 7, when the guide image is projected onto the performance area 2, the movement guide line (guide information 4) is displayed along the movement line instructed to the performer 3 within the performance area 2.

[0051] In another example, the guide image includes a movement guide mark M (guide information 4). As shown in Fig. 8, when the guide image is projected onto the performance area 2, the movement guide mark M (guide information 4) moves along the movement line instructed to the performer 3 within the performance area 2. The movement guide mark M (guide information 4) can move at the movement speed instructed to the performer 3.

[0052] <Action and effect> According to the information processing device 10 of the first embodiment, a guide image showing instructions given to the performers 3 can be projected onto the performance area 2 (floor) where the performers are performing. When instructions given to the performers 3 (such as where to stand) are shown to the performers 3 using tape stuck to the floor, it takes a lot of effort to stick and peel off the tape. For example, it is necessary to re-stick the tape for each scene performed, which is a lot of effort. According to the information processing device 10 of the first embodiment, this effort can be reduced.

[0053] Furthermore, in the case of an information processing device 10 that projects a guide image, it is possible to convey instructions to the performer 3 using various types of information. That is, in the case of the information processing device 10, it is possible to convey instructions to the performer 3 using various types of information such as marks, figures, numbers, letters, symbols, pictures, still images, and moving images. With such an information processing device 10, it is possible to convey instructions to the performer 3 accurately. Furthermore, with such an information processing device 10, it is possible to convey to the performer 3 not only instructions regarding standing positions and movement lines, but also instructions that contain a large amount of information such as movements to be made at each position, and complex instructions.

[0054] Furthermore, in the case of an information processing device 10 that projects a guide image, instructions can be conveyed to the performers 3 using moving images. With such an information processing device 10, for example, the moving speed instructed to the performers 3 can be conveyed to the performers 3 by actually moving a mark or the like. In this way, the information processing device 10 can convey information to the performers 3 that cannot be conveyed to the performers 3 by showing the instructions to the performers 3 (such as their standing position) to the performers 3 with tape stuck to the floor.

[0055] <<Second embodiment>> The information processing device 10 of the second embodiment has a function of accepting input of additional information to be added to a guide image being projected onto the performance area 2, and projecting the guide image with the additional information onto the performance area 2. This will be explained in detail below.

[0056] 10 is an example of a functional block diagram of the information processing device 10. As shown in the figure, the information processing device 10 includes an acquisition unit 11, a projection control unit 12, a reception unit 13, and an image processing unit 14.

[0057] The reception unit 13 receives input of additional information to be added to the guide image being projected onto the performance area 2.

[0058] The additional information is information added to the guide image acquired by the acquisition unit 11. The additional information can include various information. The additional information can indicate the content added to the guide image by at least one of marks, figures, numbers, letters, symbols, pictures, still images, and moving images.

[0059] The content of the additional information is not limited, and examples include, but are not limited to, notes, records, comments, and messages to the performer 3 performing in the performance area 2.

[0060] For example, the instructions to the performer 3 (such as standing position and movement line) may change during filming in a filming studio or during practice on a practice floor. In such cases, the content of the change, the fact that the change has occurred, the date and time of the change, etc. may be added to the guide image as additional information, as shown in FIG.

[0061] In addition, although not shown, the date and time when photography or practice using each guide image was performed (practice record) may be added to the guide image as additional information.In addition, although not shown, the date and time when photography or practice using each guide image was completed (completion record) may be added to the guide image as additional information.

[0062] Additionally, notes indicating problems with the instructions shown by each guide image that become apparent during filming or practice using each guide image may be added to the guide image as additional information.

[0063] Additionally, information about the performer 3 during a performance, filming, or practice using each guide image may be added to the guide image as additional information. Examples of such additional information include, for example, "Performer 3 followed the instructions in the guide image," "Performer 3 did not follow the instructions in the guide image," "Performer 3 moved as instructed in the guide image," and "Performer 3 did not move as instructed in the guide image." Another example of such additional information is information indicating the position of each performer 3 within the performance area 2 at the end of a scene using each guide image during filming using each guide image. Since the additional information indicates the actual location of each performer 3 at the end of each scene, the final position of each performer 3 in the previous scene can be easily identified by referring to this information when filming the next scene. This identification result can then be used to avoid inconsistencies in the position of performer 3 at scene boundaries.

[0064] The reception unit 13 can receive input of additional information to be added to the guide image being projected onto the performance area 2. The image processing unit 14, which will be described later, can then add the additional information to the guide image being projected onto the performance area 2. The projection control unit 12 can then cause the projection device 1 to project the guide image with the additional information onto the performance area 2.

[0065] With the information processing device 10 configured as described above, for example, during a performance, filming, or practice, additional information can be added in real time to the guide image being projected onto the performance area 2. That is, the guide image being projected onto the performance area 2 can be updated (changed) in real time based on the additional information. With this information processing device 10, for example, an operator operating the information processing device 10 can add additional information to the guide image and perform an operation to display the additional information in the performance area 2, thereby sending a message or the like to the performer 3 performing in the performance area 2.

[0066] Next, a description will be given of a means for acquiring the additional information by the reception unit 13. The reception unit 13 can acquire the additional information by one of the following reception examples 1 and 2.

[0067] Reception example 1 In reception example 1, the operator can input additional information to be added by operating an input device of the information processing device 10. Examples of the input device include, but are not limited to, a touch panel, a keyboard, physical buttons, a mouse, a joystick, and a microphone. For example, a guide image projected onto the performance area 2 is simultaneously displayed on the display of the information processing device 10. The operator can input the position on the projected image to which the additional information is to be added and the additional information to be added on the guide image displayed on the display of the information processing device 10. The reception unit 13 acquires the additional information input by the operator in this manner, for example.

[0068] Reception example 2 In reception example 2, as shown in Fig. 12, a camera 6 is installed to capture images of the performance area 2. The information processing system may have the camera 6, or the camera 6 may be used as an external device of the information processing system.

[0069] The camera 6 may be attached to the ceiling or to another member located at a relatively high position. The camera 6 is installed so as to capture the performance area 2 onto which the guide image is projected. The camera 6 may capture still images or moving images. The camera 6 detects visible light to create an image. Alternatively, the camera 6 may detect other electromagnetic waves such as infrared light to create an image.

[0070] The reception unit 13 generates additional information by analyzing the image generated by the camera 6. For example, the reception unit 13 may generate information about the performer 3 positioned in the performance area 2 described above by analyzing the image.

[0071] For example, the reception unit 13 can detect each performer 3 from the image using pre-registered appearance features (face information, costume information, physique information, etc.) of each performer 3. The reception unit 13 can also detect guidance information 4 from the image using pre-registered appearance features (type of mark, shape, type of line, etc.) of guidance information 4. Then, the reception unit 13 can compare the position of each detected performer 3 with the position of the guidance information 4 to determine whether each performer 3 is standing in the position indicated in the guidance information 4.

[0072] Alternatively, the reception unit 13 may detect each performer 3 in the image and then track each performer 3 within the video to identify the movement trajectory of each performer 3. The reception unit 13 can then compare the detected movement trajectory of each performer 3 with the movement line instructed for the performer 3 in the guidance information 4, thereby determining whether each performer 3 is following the movement line indicated by the guidance information 4. The reception unit 13 may also detect the above-mentioned movement guide mark M within the image and track this movement guide mark within the video to identify the movement trajectory of the movement guide mark M. The reception unit 13 may then compare the detected movement trajectory of each performer 3 with the movement trajectory of the identified movement guide mark M to determine whether each performer 3 is following the movement line indicated by the guidance information 4. The reception unit 13 may also compare the movement speed of each detected performer 3 with the movement speed of the identified movement guide mark M to determine whether each performer 3 is following the movement speed indicated by the guidance information 4.

[0073] The image processing unit 14 adds the additional information received by the receiving unit 13 to the guide image being projected onto the performance area 2. For example, the image processing unit 14 can add the additional information input by the operator to a predetermined position on the guide image. The image processing unit 14 can also add the additional information input by the operator to a predetermined position on the guide image designated by the operator. The image processing unit 14 may store the guide image with the additional information in a predetermined storage device.

[0074] The projection control unit 12 causes the projection device 1 to project a guide image with additional information onto the performance area 2. Fig. 11 shows an example of a guide image with additional information projected onto the performance area 2. In the example shown, the additional information is a "cross mark on the left," "the text "Changed: September 10, 2024," and an "arrow between two x marks."

[0075] Other configurations of the information processing device 10 can be the same as those in the first embodiment. An example of the configuration of the information processing system is as described in the first embodiment.

[0076] The information processing device 10 of the second embodiment can achieve the same effects as the information processing device 10 of the first embodiment. Furthermore, the information processing device 10 can add various additional information, such as notes, records, comments, and messages for the performers 3 performing in the performance area 2, to the guide image being projected onto the performance area 2. The information processing device 10 can update the guide image being projected onto the performance area 2 in real time and save the guide image with the additional information.

[0077] With this information processing device 10, the guide image can be used as a memo. Furthermore, with the information processing device 10, if additional information is added to the guide image being projected, the guide image being projected can be updated in real time. In this case, the operator operating the information processing device 10 can use the additional information added to the guide image to send a message to the performer 3 performing in the performance area 2.

[0078] <<Third embodiment>> The information processing device 10 of the third embodiment has a function of accepting an input to modify the guidance information 4 being projected onto the performance area 2, and projecting the modified guidance information 4 onto the performance area 2. This will be described in detail below.

[0079] 10 is an example of a functional block diagram of the information processing device 10. As shown in the figure, the information processing device 10 includes an acquisition unit 11, a projection control unit 12, a reception unit 13, and an image processing unit 14.

[0080] The reception unit 13 receives an input to modify the guidance information 4 included in the guidance image being projected onto the performance area 2.

[0081] The modification of the guidance information 4 includes at least one of deleting the existing guidance information 4, changing the content of the existing guidance information 4, and adding new guidance information 4.

[0082] Here, we will explain how the reception unit 13 receives input to modify the guidance information 4. The operator can operate the input device of the information processing device 10 to input to modify the guidance information 4 being projected onto the performance area 2. Examples of the input device include, but are not limited to, a touch panel, a keyboard, physical buttons, a mouse, a joystick, a microphone, etc.

[0083] For example, the guide image projected onto the performance area 2 is simultaneously displayed on the display of the information processing device 10. The operator can input, on the guide image displayed on the display of the information processing device 10, to delete existing guide information 4, change the content of the existing guide information 4, or add new guide information 4. The receiving unit 13 receives, for example, input to modify the guide information 4 from the operator in this manner.

[0084] For example, the instructions to the performers 3 (standing position, movement line, etc.) may change during filming in a filming studio or during practice on a practice floor. In such a case, for example, the operator can input to correct the guidance information 4 being projected onto the performance area 2.

[0085] The image processing unit 14 modifies the guidance information 4 being projected onto the performance area 2 based on the input for modifying the guidance information 4 received by the receiving unit 13. For example, the image processing unit 14 can delete existing guidance information 4 from the guidance image being projected onto the performance area 2, change the content of the existing guidance information 4, or add new guidance information 4.

[0086] An example of the guide image after correction is shown in Fig. 13. The guide image before correction is shown in Fig. 6. In this example, correction has been made to add a location guide mark (guide information 4).

[0087] The projection control unit 12 causes the projection device 1 to project the corrected guidance information 4 (guidance image) onto the performance area 2.

[0088] Other configurations of the information processing device 10 can be the same as those in the first and second embodiments. An example of the configuration of the information processing system is as described in the first and second embodiments.

[0089] The information processing device 10 of the third embodiment can achieve the same effects as the information processing device 10 of the first and second embodiments. Furthermore, the information processing device 10 can update the guidance information 4 being projected onto the performance area 2 in real time. The instructions (e.g., standing position, movement line, etc.) given to the performers 3 may change during filming in a filming studio, practice on a practice floor, etc. In the case of using tape attached to the floor to indicate the instructions (e.g., standing position) to the performers 3, it is cumbersome to have to apply and remove the tape every time such a change occurs. With the information processing device 10, the user can simply operate the information processing device 10 to input information to modify the guidance information 4 included in the guidance image being projected onto the performance area 2. Compared to using tape attached to the floor to indicate the instructions (e.g., standing position) to the performers 3, the information processing device 10 can reduce the effort required when the instructions to the performers 3 are changed.

[0090] <<Modifications>> Here, we will explain modified examples that can be applied to the first to third embodiments. The guide image may display other information in addition to the guide information 4 that indicates the content of instructions given to the performer 3. For example, the guide image may further indicate the positions within the performance area 2 of objects used in the performance (so-called props, etc.).
