[1-4. Recording of singing videos by singing users]
A case where a singing user shoots a singing video using the mobile terminal 3A will be described.

A singing user activates a video posting viewing application on the mobile terminal 3A when shooting a singing video. When the moving image posting viewing application is activated, the mobile terminal 3A accesses the server 4 storing a plurality of music data. Then, the singing user arbitrarily selects a song for singing by himself/herself from the moving image posting/listening application, and downloads the song data from the server 4 to the portable terminal 3A. Then, the singing user sings by reproducing the music at an arbitrary timing using the video posting viewing application. The video posting viewing application starts playing the music and also starts shooting a video with the camera 3d. That is, the singing video is a video captured by the mobile terminal 3A while the music is played back from the mobile terminal 3A.

The song data is also associated with lyric data, and when the song data is downloaded from the server 4 to the mobile terminal 3A, the associated lyric data is also downloaded to the mobile terminal 3A. In the following description, it is assumed that song data also includes lyrics data.

FIG. 4 is an example of a display state (hereinafter referred to as "screen display") on the screen 3a of the mobile terminal 3A when shooting a singing video.

As shown in FIG. 4, the screen 3a is divided into a lyrics display area 50A and a photographed image display area 50B. The lyric display area 50A includes a lyric image 52 indicating the lyrics of the song sung by the user, a pitch image 54 indicating the pitch of the song, and a progress bar 56 indicating the progress of shooting.

The lyric image 52 and the pitch image 54 are updated as the music progresses. In this embodiment, as an example, the lyrics image 52 and the pitch image 54 are updated by several phrases and displayed in the lyrics display area 50A. Note that the update timing of the lyrics image 52 and the pitch image 54 may be the same or different.

As an example, the lyrics image 52 displays the lyrics in multiple stages (two stages in the example of FIG. 4), and the colors of the lyrics in the upper stage match the progress of the music so that the singing user can grasp the lyrics to be sung at present. Together, it changes from the left end to the right end. When the color change of the lyrics in the upper row reaches the right end, the lyrics in the lower row rise and are displayed in the upper row, and new lyrics are displayed in the lower row. change to the right end.

In the pitch image 54, for example, a plurality of pitch bars 54A are displayed in steps in the horizontal direction according to the intensity of the pitch. Then, the color of the pitch bar 54A changes from the left end to the right end and the pointer 54B moves from the left end to the right end as the music progresses so that the singing user can grasp the pitch of the lyrics to be sung at present. When the color of the pitch bar 54A changes and the pointer 54B reaches the right end, the pitch image 54 showing the next pitch is updated and displayed.

As an example, the progression bar 56 indicates the length of the entire song from the left end to the right end. When the music starts to be reproduced, the pointer 56A indicating the music reproduction position moves from the left end to the right end, and when the pointer 56A reaches the right end, the music ends. The progress bar 56 passed by the pointer 56A is displayed thicker than the position before progress.

Recording of the singing video is started after a predetermined time (for example, 10 seconds) after the singing user selects a song and clicks a recording start button (not shown) displayed on the screen 3a. Also, the start and end of video recording may coincide with the start and end of the music, but this is not limiting, and the video recording may start a predetermined time (for example, 5 seconds) before the start of the music. However, the video recording may end after a predetermined time (for example, 5 seconds) after the end of the music.

A singing user connects an earphone to the earphone terminal 3e, listens to the reproduced music using the earphone, and sings along with the music. The mobile terminal 3A shoots the singing user with the camera 3d and records the singing user's singing with the microphone 3c. That is, the microphone 3c does not acquire the sound of the music being reproduced. Then, the portable terminal 3A records the singing voice of the singing user acquired by the microphone 3c and uses it as singing data.

The singing data may be obtained by extracting the frequency band of human voice by filtering. This filtering process removes noise caused by the surrounding environment of the singing user from the singing data, so that the recorded singing voice of the singing user becomes clearer.

Then, the moving image posting viewing application combines the song data and the singing data with the recorded data to create singing moving image data that can be transmitted to the server 4 . As an example, the user can select one of the following two types of timing for transmitting the song video data to the server 4, that is, timing for uploading to the video posting site.

One is live distribution in which a singing user sings and uploads singing video data to a video posting site in real time. In the live distribution, the viewing user will view the singing by the singing user in real time. The other is non-live distribution in which the singing user uploads the singing video data to the video posting site at any timing after the singing of the song is completed.

When live distribution is to be performed, the singing user performs settings for live distribution before recording the singing video, so that the singing video data is uploaded to the video posting site at the same time as the recording of the video is started. In the case of live distribution, the singing video data may be uploaded to the video posting site without being stored in the mobile terminal 3A.

In addition, as settings for live distribution, the first live distribution setting that allows the viewing user to view the singing video in the live distribution, and the second live distribution that allows the viewing user to view the singing video even after the live distribution Any of the settings can be set by the singing user. That is, in the first live distribution setting, when the live distribution ends, the singing video data is deleted from the server 4, and the viewing user cannot view the live-distributed singing video after the live distribution ends. On the other hand, in the second live distribution, the server 4 continues to store the singing video data even after the live distribution ends, so that the viewing user can view the singing video as a non-live distribution even after the live distribution ends.

In the case of non-live distribution, the singing video data is temporarily stored in the mobile terminal 3A, and the singing user operates the video posting viewing application to upload the singing video to the video posting site at any timing.

[1-5. Viewing of singing video by viewing user]
A case where the viewing user uses the mobile terminal 3B to view the singing video will be described.

When viewing a singing video, the viewing user activates the video posting viewing application on the mobile terminal 3B. When the video posting viewing application is activated, the mobile terminal 3B accesses the server 4 storing a plurality of singing video data, that is, the video posting site. Then, the viewing user selects a singing video to be viewed via the video posting viewing application and displays it on the screen 3a. An example of the method of distributing the singing video to the mobile terminal 3B by the server 4 is streaming distribution.

FIG. 5 is an example of the screen display of the portable terminal 3B when viewing a singing video, and shows the screen display when live distribution is being performed.

A singing video is displayed on the screen 3a, and a singing user display area 50C, a lyrics display area 50D, and a comment input display area 50E are provided. The singing user display area 50C, the lyrics display area 50D, and the comment input display area 50E may be superimposed and displayed on the singing video.

The singing user display area 50C displays the user name of the singing user who posted the singing video, whether or not it is a live distribution, and the name of the song being sung.

The lyrics of the singing video are displayed in the lyrics display area 50D. The displayed lyrics are, for example, a plurality of phrases each, and the color of the lyrics changes from the left end to the right end as the music progresses. As an example, the lyrics display area 50D may display the lyrics in a plurality of stages. In this case, when the change in the color of the lyrics in the upper row reaches the right end, the lyrics in the lower row rise and are displayed in the upper row, and new lyrics are displayed in the lower row. changes from the left end to the right end.

In the comment input display area 50E, a comment input field is displayed, and the comments of the viewing user who is viewing the singing video are displayed together with the user name. As an example, each time a comment is input by the viewing user, the comment is additionally displayed at the top of the comment input display area 50E, and the comments that have been displayed up to that point are moved downward. When the comment cannot be displayed in the comment input display area 50E, a scroll bar (not shown) is displayed on the right side of the comment display area. Comments that were not displayed in 3a are displayed.

Further, the screen 3a displays operation icons 58A to 58D for the viewing user to perform various operations.

The operation icon 58A is an icon that is clicked when the viewing user sympathizes with the singing video that the viewing user is viewing, and the total number of clicks of the operation icon 58A for the singing video is displayed above the operation icon 58A. be.

The operation icon 58B is an icon that is clicked when the viewing user requests a battle (hereinafter referred to as "competition singing") against the singing user who is live-distributing the singing video displayed on the screen 3a. In the competition singing, a plurality of singing videos (first singing video, second singing video) by different singing users are displayed simultaneously on the screen 3a of the mobile terminal 3B of the viewing user, and the singing video alternately sings the same song. be. That is, the viewing user who clicked the operation icon 58B becomes the singing user who performs the competition singing.

The operation icon 58C is an icon that is clicked when the viewing user makes various settings for the video posting viewing application.

The operation icon 58D is an icon that is clicked by the viewing user when superimposing a decoration image on the singing video displayed on the screen 3a. Note that the decoration image according to the present embodiment is priced according to its type, and can be purchased by the viewing user by charging. Then, the viewing user clicks the operation icon 58D to superimpose the decoration image on the singing video that the viewing user is viewing. The singing user of the singing video on which the decoration image is superimposed receives money corresponding to the superimposed decoration image from the operator of the video posting site. That is, the superimposition (display instruction) of the decoration image on the singing video by the viewing user corresponds to a so-called tipping for the singing user.

[1-6. Overview of the competition singing function]
The video posting viewing application according to the present embodiment has a competition function in which a plurality of users who are performers compete with each other for the superiority of their own performance videos. The battle function according to the present embodiment is a kind of so-called karaoke battle, and as illustrated in FIG. 6, a plurality of singing videos (first singing video 60A, second singing video 60B) by different singing users It is a competition singing function displayed simultaneously on the screen 3a of the portable terminal 3B. It should be noted that the competition singing function is a function executed by the server 4 .

FIG. 6 is a screen display of the viewing user's portable terminal 3B in the competition singing. The display of "VS" shown in FIG. 6 is displayed at the start of the competition song, and the display is stopped after a predetermined time (for example, 3 seconds) has passed since the competition song was started. Also, the screen display of the singing user's portable terminal 3A may be, for example, the same as that shown in FIG. (See FIG. 8, which will be described later).

In order for the competition singing to be performed, a singing user (hereinafter referred to as "first singing user") requests another singing user (hereinafter referred to as "second singing user") to simultaneously distribute singing videos (hereinafter referred to as (referred to as a "competition request") is made, and the second singing user needs to approve the competition request.

More specifically, the first singing user activates the video posting viewing application on his/her mobile terminal 3A1, and transmits a competition request to the second singing user who is live-distributing the singing video using the video posting viewing application. . The competition request is sent by the first singing user clicking the operation icon 58B. The music to be sung in the competition singing is selected by the first singing user. Information (title and singer name) indicating the selected song (hereinafter referred to as "match song") is sent to the second singing user together with the match request.

The competition request transmitted from the mobile terminal 3A1 is transmitted via the server 4 to the mobile terminal 3A2 of the second singing user. An image corresponding to the received competition request is displayed on the screen 3a of the portable terminal 3A2, and the second singing user clicks a predetermined image displayed on the screen 3a when accepting the competition request.

Then, when the second singing user accepts the competition request from the first singing user, the server 4 determines that the first singing video 60A by the first singing user and the second singing video 60B by the second singing user are on the mobile terminal 3B. By distributing so as to be displayed on the screen 3a at the same time, the competition singing is started. As a result, the viewing user can view the competition singing (real-time competition) between the first singing user and the second singing user in real time. In addition, in the following description, the 1st singing animation 60A and the 2nd singing animation 60B distributed in competition singing are named generically, and are also called a competition singing animation.

In this way, the competition singing function accepts a singing video competition request from the first singing user to the second singing user, and when the second singing user approves the competition request, the first singing video 60A and the second singing The video 60B is distributed so as to be simultaneously displayed on the screen 3a of the portable terminal 3B. Therefore, the competition singing function enables singing users to compete with each other in their own singing by using respective singing videos, and allows viewing users to simultaneously view a plurality of competing singing videos.

It is also assumed that the second singing user accepts the match request but does not accept the match song. For such a case, the competition singing function transmits information indicating the competition song change and the competition song selected by the second singing user from the second singing user's mobile terminal 3A2 to the first singing user's mobile terminal 3A1. and may have a function of requesting the approval of the first singing user.

[1-6-1. Alternate Singing in Competition Singing]
In the competition singing function according to the present embodiment, the first singing user and the second singing user alternately sing the same song (hereinafter referred to as "alternate singing").

Alternate singing may be, for example, a form in which the second singing user sings the same song after the first singing user has finished singing one song. As shown, music is virtually divided into a plurality of areas, and the order of singing users who sing for each divided area 68 is set (hereinafter referred to as "alternate performance setting"). As a result, the first singing user and the second singing user alternately sing the same piece of music according to the alternating performance setting, so the viewing user is aware of the difference in singing ability between the first singing user and the second singing user. can be clearly recognized, and the competition singing can be enjoyed more. In the following description, the order of singing users who sing is referred to as alternate singing order.

Note that the competition singing function, for example, allows the singing user to recognize the divided area 68 in which the singing user sings by highlighting the lyric portion sung by the singing user. The highlighting is a color change, a thickness change, or the like of the lyrics.

In the example of FIG. 7, the divided area 68 is set so that the first singing user and the second singing user sing alternately, and the divided area 68 where the first singing user and the second singing user sing together. is also set. The divided areas 68 are set in advance based on, for example, phrases, choruses, or bars of music, and the length of time of each divided area 68 does not necessarily have to be the same.

The alternate singing order is determined along with the decision to perform the competition singing. For example, it is set so that the first singing user who requested the competition sings first, and the second singing user sings later. Note that the divided area 68 in which the first singing user and the second singing user sing together may be set in advance for each piece of music.

Also, the alternate singing order set based on the divided areas may be changed dynamically. For example, a singing user with a relatively higher total score obtained by a voting function, which will be described later, may have more divided areas 68 for singing. More specifically, the total score for each singing user (singing video) is compared for each predetermined timing of the song, and the singing user with a relatively large total score continues the plurality of divided areas 68 after that. sing. In this case, the maximum number of divided areas 68 that can be continuously sung is predetermined.

As a result, a singing user with a relatively high total score has more divided regions 68 to sing, while a singing user with a relatively low total score has fewer divided regions 68 to sing from. Therefore, a singing user with a relatively high total score can appeal his or her singing ability to the viewing user and attract the viewing user more.

[1-6-2. Screen display and audio output during alternate singing]
As described above, FIG. 6 is the display screen of the viewing user's mobile terminal 3B in the competition singing, and both the first singing video 60A and the second singing video 60B are displayed in the same image size. Then, a display (“NOW PLAYING” in FIG. 6) that allows the viewing user to recognize the singing video in which the song is being performed is performed.

Here, a singing video and its voice that are not being sung are not of interest to the viewer user, and may distract the viewer user who is watching the song being sung.

Therefore, the competition singing function according to the present embodiment distributes the singing video to the mobile terminal 3B so that the voice of the singing video during singing is output and the voice of the singing video that is not singing is not output. Further, the server 4 distributes the singing video to the mobile terminal 3B so that the singing video during singing is displayed on the screen 3a of the mobile terminal 3B in a larger size than the singing video when the song is not being performed.

In addition, the number of fans increases when the viewing user registers himself/herself as a fan of the singing user through the video posting viewing application. There is no limit to the number of singing users that can be registered as fans by viewing users.

In addition, the competition singing function may accept a competition request even if the number of fans is the same as long as other conditions are satisfied, or if the second singing user approves even if the number of fans is not the same. A battle request may be accepted. On the other hand, the competition singing function may accept only competition requests with approximately the same number of fans. Here, "only" means, for example, that even if other conditions are satisfied, a battle request with a different number of fans will not be accepted.

In addition, the competition singing function may give the singing user a consideration corresponding to the total evaluation score obtained by the singing user who won the competition singing by voting for himself/herself. The consideration here is money, or points that can be used in a video posting viewing application (video posting site) or other online services. In addition, the singing user who won the competition singing may obtain a consideration according to the score obtained by summing not only the total evaluation score of himself but also the total evaluation score of the opponent (so-called total collection).

Although audio output and screen display are performed, the enlargement display function according to this embodiment may be executed when the first dance user and the second dance user dance together.

[2-1-2. Featured video judgment function]
The attention movie determination function extracts an image (hereinafter referred to as a "dancer image") showing a dancer (person) who is the subject from the dance movie at predetermined time intervals, and the difference in the extracted dancer among the plurality of dance movies is the largest. The dance video is determined to be the target video. Note that the image extraction interval (hereinafter referred to as “image extraction interval”) is, for example, 0.5 seconds, and may be defined by the number of frames instead of time.

More specifically, the attention moving image determination function extracts dancer images at predetermined time intervals (0.5 seconds) from the start of the dance moving image, and derives the difference between the dancer images before and after the image extraction interval. Then, the attention movie determination function compares the difference between the dance movies at the same timing derived for each of the first dance movie 60C and the second dance movie 60D, and the difference between the first dance movie 60C and the second dance movie 60D is greater. A large dance video is set as the attention video. Note that extraction of a person from a dance video may be performed by, for example, a known image analysis method.

In this way, the attention moving image determination function directly determines the magnitude of the dancer's movement from the dancer image included in the dance moving image, so it is possible to accurately determine the dance moving image in which the subject, the dancer, moves relatively quickly. Note that the dance moving image according to the present embodiment is a moving image in which the whole body of the dancer is shot and the dancer is shot in a size that allows image analysis in order to perform image analysis of the dancer image.

Further, the attention moving image determination function according to the present embodiment determines the difference in movement of the dancer, who is the subject, based on the movement of the dancer's limbs.

That is, in the example of FIG. 16, the dancer image of the first dance animation 60C shown in FIG. 16(A) changes after a predetermined time as shown in FIG. 16(B), and the second dance animation shown in FIG. The dancer image of moving image 60D changes as shown in FIG. 16(D) after a predetermined period of time.

In the example of FIG. 16, as surrounded by the dashed line area, the first dance video 60C shows large movements of the left hand and the right leg, while the second dance video 60D shows only slight movements of the left and right legs. Dance animation 60C has a larger difference between the dancer images. Therefore, the first dance moving image 60C is the image of interest. As an example, the movement of the limbs is the movement of the tip positions of the limbs, and the movements of the tip positions of the limbs are derived from changes in the coordinates indicating the tip positions.

In this way, the attention moving image determination function determines the difference in movement of the dancer, who is the subject, based on the movement of the dancer's limbs, so that the movement of the dancer can be determined more accurately.

Here, in the dance, the dancer may not move momentarily. In such a case, when a dancer (subject) in another dance video that is not the target video moves, the other dance video is determined to be the target video. May be enlarged.

Therefore, when the movement of the dancer in the target video becomes smaller than the movement of the dancer in the other dance video for a predetermined time (for example, 1 second), the enlargement display function can be used to switch the other dance video as the target video. good. In other words, even if the movement of the dancer in the target video becomes smaller than the movement of the dancer in the other dance video, the other dance video will not be switched to the target video if it is less than the predetermined time.

As a result, even if the dancer in the target video temporarily stops moving, it is possible to prevent another dance video that is not performing a dance from becoming the target video.
