[Operation of Information Processing System 100]

Next, an operation of the information processing system 100 will be described.

In the information processing system 100, when a performance is performed in the electronic musical instrument 2, images (first image, second image) corresponding to the performance are generated in the information processing apparatus 1, and the generated images are displayed on the display device 4. The generated second image and performance information are transmitted to the server 3. The server 3 stores the second image and performance information. The server 3 generates the Web page and its URL information for viewing the second image and listening to the performance based on the performance information. The generated URL information is transmitted to the information processing apparatus 1. When the information processing apparatus 1 receives the URL information transmitted from the server 3, the two-dimensional code representing the URL information and a thumbnail of the second image are generated and printed out by the label printer 5. As a result, the URL information for accessing the Web page for viewing the second image and listening to the performance based on the performance information is transmitted to the performer. When the camera of the user terminal 6 is held over the two-dimensional code output by the label printer 5, the two-dimensional code is read by the user terminal 6, URL information is acquired, and the Web page can be accessed by the acquired URL information. That is, the user can view the second image and listen to the performance based on the performance information.

FIG. 3 is a diagram showing a sequence in the information processing system 100 from the start of the performance by the performer in the electronic musical instrument 2 to the output of the URL information by the label printer 5. The sequence shown in FIG. 3 will be described below.

The electronic musical instrument 2 determines that there is a performance operation (key depression or key release) whether or not (step S1), if it is determined that there is the performance operation (step S1; YES), in other words, if the electronic musical instrument 2 detects performance operation, the electronic musical instrument 2 generates performance information (e.g., MIDI data) based on the performance operation and transmits the performance information to the information processing apparatus 1 (step S2). Thereafter, the process proceeds to step S3.

If it is determined that there is no performance operation (step S1; NO), the electronic musical instrument 2 executes the process of step S3.

In step S3, the electronic musical instrument 2 determines whether or not a predetermined time (a set time) has elapsed in a state where there is no performance operation (step S3).

If it is determined that the predetermined time has not elapsed in the state where no performance operation is performed (step S3; NO), the process returns to step S1.

If it is determined that the predetermined time has elapsed in the state where there is no performance operation (step S3; YES), the electronic musical instrument 2 determines that the performance has ended and ends these processes.

In the information processing apparatus 1, the control unit 11 determines whether or not the performance information has been input from the electronic musical instrument 2 via the communication unit 15 (step S4).

If it is determined that the performance information has been input from the electronic musical instrument 2 via the communication unit 15 (step S4; YES), in other words, if the information processing apparatus 1 detects the performance information, the control unit 11 acquires the input performance information and analyzes the performance information in real time. The control unit 11 generates the first image corresponding to the performance based on the analysis result. Then, the communication unit 15 transmits the generated first image to the display device 4, instructs the display device 4 to display the first image, and causes the display device 4 to display the first image (step S5), and the process proceeds to step S6. The control unit 11 may display the first image on the display unit 14.

In this embodiment, an expression “instruct” can be read as “control”.

In step S5, the control unit 11 analyzes the input performance information and determines the tonality of the music, pitch (note) velocity and tempo. The control unit 11 determines the type of element to be drawn (for example, an image of a flower or a leaf), the size of the element, and the like based on the determined information, and generates the first image corresponding to the performance. As a method for generating the first image and the second image from the performance information, for example, the method described in Japanese published Patent Application No. 2019/101168 can be used, but the method is not limited thereto. The control unit 11 transmits the generated first image to the display device 4 so that the display device 4 displays the first image. The control unit 11, as shown in FIG. 4, records an image parameter used to generate the first image in the RAM. The image parameter used to generate the first image includes pitch (note) and velocity value included in the performance information, tonality or tempo, which is the result of analysis of the performance, an element ID indicating the type of the drawn element, the size of the element, and the like. The element corresponding to the element ID is stored in the storage unit 12.

When it is determined that the performance information is not input from the electronic musical instrument 2 through the communication unit 15 (step S4; NO), the control unit 11 proceeds to step S6.

In step S6, the control unit 11 determines whether or not the predetermined period of time has elapsed with no performance information is input (step S6).

If it is determined that the predetermined time has not elapsed with no input of performance information (step S6; NO), the process returns to step S4, and the control unit 11 repeatedly executes steps S4 to S6.

If it is determined that the predetermined time has elapsed without input of the performance information (step S6; YES), the control unit 11 determines that the performance has ended and generates the second image that summarizes the entire performance. Then, the control unit 11 transmits the generated second image from the communication unit 15 to the display device 4. Then, the control unit 11 instructs the display device 4 to display the second image and causes the display device 4 to display the second image (step S7).

In step S7, the control unit 11 generates the second image based on the image parameters (image parameter group) used for generating the plurality of first images generated during the performance. The image parameters (image parameter group) are stored in the RAM. The control unit 11 transmits the generated second image from the communication unit 15 to the display device 4 and displays the second image on the display device 4 (see FIG. 1). The control unit 11 may display the second image on the display unit 14.

Next, the control unit 11 acquires current date and time as the performance date and time when the performance was performed and stores the performance date and time information in the RAM (step S8).

Next, the control unit 11 transmits data of the second image, the performance information, and the image parameters from the communication unit 15 to the server 3 (step S9).

When the server 3 receives the data of the second image, the performance information, and the image parameter from the information processing apparatus 1 (step S10; YES), the server 3 stores the received data in the storage unit of the server 3 in association with each other (step S11).

Next, the server 3 generates the Web page for viewing the second image and for listening to the performance based on the performance information, and stores data related to the Web page in the storage unit (step S12).

Then, the server 3 generates URL information for accessing the generated Web page and transmits the URL information to the information processing apparatus 1 (step S13).

When the information processing apparatus 1 receives the URL information from the server 3 via the communication unit 15 (step S14; YES), the control unit 11 acquires the received URL information and generates the two-dimensional code representing the URL information and the thumbnail of the second image (step S15).

For example, the control unit 11 encodes the received URL information to generate the two-dimensional code (e.g., a QR code (R)) representing the URL information. Further, for example, the control unit 11 applies dither processing to the second image to binarize it and reduces the image size, thereby generating a black and white binary thumbnail.

Then, the control unit 11 transmits the generated data of the two-dimensional code, the thumbnail of the second image, and the performance date information to the label printer 5 from the communication unit 15. The control unit 11 instructs the label printer 5 to output the two-dimensional code, the thumbnail of the second image, and the performance date information (step S16).

The label printer 5 prints out the two-dimensional code, the thumbnail of the second image, and the performance date information in accordance with the instruction of the information processing apparatus 1 (step S17).

FIG. 5 is a diagram showing an example of the second image 141 output by the display device 4 and a label 51 output by the label printer 5.

As shown in FIG. 5, the label 51 includes the two-dimensional code 51a indicating URL information, the thumbnail 51b of the second image, and the performance date and time 51c.

The label printer 5 uses the long recording medium wound in the roll shape (for example, a tape member), and the size of the two-dimensional code is very small compared with original size of the second image. Therefore, even when the two-dimensional code is printed by the label printer 5, the frequency of running out of a paper or running out of ink is very low. Therefore, by using the label printer 5 to automatically print out the two-dimensional code representing the URL information for accessing the second image and the performance information, it is possible to automatically provide the URL information for accessing the second image and the performance information to the performer without requiring any manual operation. In other words, it is possible to provide the player with the image or the performance information generated in accordance with the performance in a manner that can be shared with others.

Further, by printing not only the two-dimensional code 51a but also the thumbnail 51b of the second image and the performance date and time 51c, the performer can distinguish ones two-dimensional code from the two-dimensional code of another performer. As a result, it is possible to reduce the possibility that the label on which the two-dimensional code for another player is printed is mistakenly carried away.

The performer acquires the label 51 output from the label printer 5, activates the two-dimensional code reader application on the user terminal 6 held by the performer, and holds the user terminal 6 over the two-dimensional code 51a of the label 51.

FIG. 6 is a diagram showing a flow of a sequence executed between the user terminal 6 and the server 3 when the two-dimensional code reader application is activated in the user terminal 6 and the user terminal 6 is held over the two-dimensional code 51a of the label 51. The sequence shown in FIG. 6 will be described below.

When the user terminal 6 waits for the photographing of the two-dimensional code 51a by the camera and the two-dimensional code 51a is photographed (step S21; YES), the user terminal 6 decodes the photographed two-dimensional code 51a and acquires URL information (step 22).

Next, the user terminal 6 determines whether or not access to the Web page based on the acquired URL information is instructed by the user operation (step S23).

When it is determined that access to the Web page based on the acquired URL information is instructed (step S23; YES), the user terminal 6 accesses the server 3 based on the acquired URL information and requests transmission of the Web page specified by the URL information (step S24).

When the user terminal 6 requests access to the Web page based on the URL information, the server 3 reads the Web page specified by the URL information and transmits it to the user terminal 6 (step S25).

The user terminal 6 displays the Web page transmitted from the server 3, i.e., the Web page for viewing the second image and listening the performance based on the performance information, by the Web browser (step S26).

In step 26, the Web page displays the second image and user interfaces (play button, stop button, pause button, etc.) for viewing the performance based on the performance information. The performer can enjoy viewing the second image and listening to the performance by playing the performance information on the Web page. Further, a DL button is displayed on the Web page for instructing a download of the second image obtained by reconstructing the second image according to the display screen of the user terminal 6.

When the user terminal 6 is instructed to download the second image by pressing the DL button from the Web page (step S27; YES), the user terminal 6 requests the server 3 to download the second image and transmits screen information (for example, the number of horizontal pixels and the number of vertical pixels) of the user terminal 6 to the server 3 (step S28).

When the server 3 receives the request for downloading the second image and the screen information from the user terminal 6 (step S29; YES), the server 3 reconstructs the second image for wallpaper in accordance with the size of the display screen of the user terminal 6 (step S30), and transmits the reconstructed second image (reconstructed image) to the user terminal 6 (step S31).

The server 3 reads the image parameters received together with the second image displayed on the Web page from the storage unit, and reconstructs the second image suitable for the size and resolution of the display screen of the user terminal 6 based on the read image parameters. In the case where the specification of the control unit of the server 3 is high and performance information can be read and analyzed at high speed, the second image according to the display screen of the user terminal 6 may be reconstructed from performance information without using the image parameters. In this case, it is not necessary to transmit the image parameter from the information processing apparatus 1 to the server 3 in step S9 of FIG. 3.

The user terminal 6 receives the second image transmitted from the server 3 (step S32).

The players can enjoy the second image by downloading it and displaying it as wallpaper.

When the end of display of the Web page is instructed (step S33; YES), the user terminal 6 closes the Web page and ends the sequence executed with the server 3.

As described above, since the information processing system 100 generates the URL information for accessing the second image and the performance information corresponding to the performance of the performer and outputs the two-dimensional code representing the URL information, it is possible to provide the URL information to the performer without the need for manual operation (without user intervention). Therefore, the second image and the performance information generated in accordance with the performance can be easily provided to the performer.

Also, by sharing the two-dimensional code (URL information) acquired by the performer with others, it is possible to enjoy the second image and the performance information with others.

In the embodiment described above, it is assumed that the label printer 5 prints out the two-dimensional code representing the URL information for accessing the second image corresponding to the performance and the performance information. However, the method of outputting the two-dimensional code is not limited to this example. For example, the control unit 11 can superimpose the two-dimensional code representing the URL information on the second image, and can instruct the display device 4 or the display unit 14 of the information processing apparatus 1 to display the second image superimposed with the two-dimensional code, so that the second image is displayed on the display device 4 or the display unit 14. In this case, the control unit 11 may control the display device to display the second image without displaying the two-dimensional code for a certain period of time, or display the two-dimensional code in an inconspicuous position of the second image so as not to impair an artistic quality of the second image.

In the above-described embodiment, when the control unit 11 of the information processing apparatus 1 receives the URL information from the server 3, the control unit 11 generates the two-dimensional code of the URL information and causes the label printer 5 to print it out in step S15-16 shown in FIG. 3. However, the method of outputting the URL information is not limited to this example.

For example, in steps S15-S16 in FIG. 3, the control unit 11 generates a digital watermark image in which the URL information is embedded in the second image, the digital watermark image can be transmitted to the display apparatus 4 so as to instruct the display apparatus 4 to display the digital watermark image.

Alternatively, the display of the digital watermark image can be instructed to the display unit 14 to display the digital watermark image. In this case, in step S7 in FIG. 3, the second image is not displayed on the display apparatus 4 and the display unit 14 of the information processing apparatus 1. Therefore, the information processing apparatus 1 prevents the performer from taking the second image without including the digital watermark.

When the digital watermark image displayed by the display device 4 is photographed by the user terminal 6, the user terminal 6 acquires the URL information from the digital watermark image. Since the processing after acquiring the URL information is the same as the processing in step S23 and subsequent steps in FIG. 6, the description thereof is incorporated.

In the above embodiment, although the Web page is generated for each performance, a common Web page can be prepared in advance. The URL information of the common Web page is displayed, for example, in the form of a two-dimensional code, at a place where the performer can see. For example, a card on which the two-dimensional code is printed can be placed on the electronic musical instrument 2 so that the performer can take it home. A poster on which the two-dimensional code is printed can be put up near the electronic musical instrument 2. The server 3 receives the second image, performance information and image parameters from the information processing apparatus 1, the received second image and the received performance information are added to the common Web page. The performer can view the common Web page by taking a picture of the two-dimensional code representing URL information of the common Web page with the camera in the user terminal 6. The second image and the performance information added to the Web page are deleted after a certain period of time in the server 3.

According to above embodiments, data corresponding to the performance within a predetermined period of time is uploaded to the common Web page in addition to the performance of the performer himself or herself. Therefore, the performer can view the second image or the performance of another person by searching based on the time or place of the performance. It is also possible to share and enjoy the data of the second image and the performance information with others. Further, since individual URL information is not generated for each performance, it is possible to omit the step of generating a different two-dimensional code for each performance and presenting it to the performer. It also avoids confusion when someone doesn't come to pick up the printed two-dimensional code. In addition, when the performer plays a plurality of pieces of music, the performer can access a plurality of second images and a plurality of pieces of performance information with one access.

As described above, the control unit 11 of the information processing apparatus 1 acquires performance information corresponding to the performance operation from the electronic musical instrument 2, generates the second image corresponding to the performance based on the acquired performance information, and causes the server 3 to store the second image and the performance information. Then, the control unit 11 acquires the URL information for accessing the stored second image and the performance information from the server 3, and instructs the label printer 5, the display device 4, or the display unit 14 to output the acquired URL information. Therefore, the URL information for accessing the second image and the performance information can be automatically provided to the performer without manual (user) intervention. Therefore, the second image and the performance information generated in accordance with the performance can be easily shared with others.

For example, the control unit 11 generates the two-dimensional code representing the URL information and instructs the output of the generated two-dimensional code to the label printer 5, the display device 4, or the display unit 14 to output the generated two-dimensional code.

Therefore, the performer can easily access the second image and the performance information by holding the user terminal 6 over the two-dimensional code. In addition, since the performer can bring back the two-dimensional code, it is also possible to access the second image and the performance information later.

For example, the control unit 11 generates the thumbnail of the second image and instructs the label printer 5 to output the two-dimensional code and the thumbnail. Therefore, the performer can identify his or her own two-dimensional code, and it is possible to prevent another performer from mistakenly bringing back the label on which the two-dimensional code of another performer is printed.

Further, for example, the control unit 11 acquires performance date and time information in which a performance corresponding to the performance information has been performed and instructs the label printer 5 to output the two-dimensional code and performance date and time information. Therefore, it is possible for the player to identify his or her own two-dimensional code, and it is possible to prevent another player from erroneously bringing back the two-dimensional code.

For example, the control unit 11 superimposes the two-dimensional code on the second image and instructs the display device 4 or the display unit 14 to output the second image superimposed with the two-dimensional code. Therefore, the performer can easily access the second image and the performance information by holding the user terminal 6 over the two-dimensional code.

For example, the control unit 11 generates the digital watermark image in which the URL information is embedded in the second image, and instructs the display device 4 or the display unit 14 to output the digital watermark image. Therefore, the second image and the performance information can be easily accessed only by photographing the digital watermark image with the user terminal 6 installed with an application for reading information embedded in the digital watermark image.

Further, for example, the server 3 generates the Web page for viewing the second image and listening the performance based on the performance information and generates the URL information of the Web page, and transmits the generated Web page and the URL information to the information processing apparatus 1. Therefore, the performer can easily view the second image and listening the performance based on the performance information.

For example, when the server 3 receives a request to download the second image from the user terminal 6 accessed based on the URL information, the server 3 acquires screen information of the display screen of the user terminal 6 from the user terminal 6, generates a reconstructed image corresponding to the display screen of the user terminal 6 based on the acquired screen information as the second image, and transmits the generated reconstructed image to the user terminal 6.

Therefore, the second image corresponding to the display screen of the user terminal 6 can be provided to the performer.

It should be noted that the description contents in the above-described embodiment and the variation embodiments are examples of the information processing method, information processing apparatus, program, and information processing system according to the present disclosure, and are not limited thereto.

For example, in the above-described embodiment, the information processing apparatus 1 and the electronic musical instrument 2 are described as being separate from each other. However, the information processing apparatus 1 and the electronic musical instrument 2 can be integrated. For example, the function of the information processing apparatus 1 can be provided in the electronic musical instrument 2.

In the above embodiment, the storage device is the server 3, the second image, the performance information and the image parameter are stored in the server 3, and the server 3 generates the URL information for accessing the second image and the performance information. However, the storage unit 12 of the information processing apparatus 1 can function as the storage device. That is, the control unit 11 of the information processing apparatus 1 can store the second image, the performance information, and the image parameter in the storage unit 12 of the information processing apparatus 1, and generate the URL information for accessing the second image and the performance information. For example, the control unit 11 can store the second image, the performance information, and the image parameter in the storage unit 12 of the information processing apparatus 1, generate the Web page for viewing the second image and listening the performance based on the performance information, and generate the URL information for accessing the Web page.

In the above-described embodiment, in order to provide both the second image and the performance information to the performer, the second image and the performance information are stored, and address information (the URL information) for accessing both is generated and output.
