Description

[Technical field]

[0001] The present invention relates to a karaoke machine having a function of displaying a background image while singing karaoke. [Background technology]

[0002] Many karaoke machines are equipped with a function to display background images along with the lyrics of a song on a large display connected to the karaoke machine (hereinafter referred to as a "karaoke display") when karaoke is being sung. In conventional karaoke machines, the background images are usually created by the karaoke service provider. The background images are pre-stored in the karaoke machine or distributed from a server device to the karaoke machine. Furthermore, the background images displayed when singing karaoke are selected by the karaoke machine based on factors such as the genre of the song being sung.

[0003] Meanwhile, karaoke machines with a function of displaying an image transmitted from a user's mobile terminal to the karaoke machine as a background image are becoming popular (see Non-Patent Document 1 below). After wirelessly connecting the mobile terminal to the karaoke machine, the user can manually operate the mobile terminal to select an image stored in the mobile terminal and transmit the selected image to the karaoke machine at any time. The transmitted image is immediately displayed on the karaoke display. The user can transmit an image taken with a camera provided on the mobile terminal to the karaoke machine and have it displayed on the karaoke display. With this function, the user can, for example, sing karaoke with an image of his or her karaoke companions in the background, which can liven up the karaoke experience.

As will be described later, the karaoke device 11 transmits an image data transmission request command to each of the terminal devices 51A, 51B, 51C, and each of the terminal devices 51A, 51B, 51C transmits image data, user identification information, and song identification information to the karaoke device 11, and these commands, data, and information are transmitted between the karaoke device 11 and each of the terminal devices 51A, 51B, 51C via the server device 41 as described above. By performing communications between the karaoke device 11 and each of the terminal devices 51A, 51B, 51C via the server device 41 that is directly managed by the karaoke service provider, a high level of information security can be implemented in the karaoke system 1.

[0025] [The general flow of karaoke] A general flow of karaoke when users A, B, and C sing karaoke in a karaoke room where a karaoke device 11 is installed will be described. First, user A operates terminal device 51A to start a remote control application, connects terminal device 51A to karaoke device 11, and logs in to karaoke device 11. Similarly, user B also operates a remote control application, connects terminal device 51B to karaoke device 11, and logs in to karaoke device 11. Similarly, user C also operates a remote control application, connects terminal device 51C to karaoke device 11, and logs in to karaoke device 11. Next, among users A, B, and C, a user who wants to sing karaoke operates his / her terminal device 51A, 51B, or 51C to select a song and reserve a karaoke performance of the selected song. After the karaoke performance of the reserved song is started by karaoke device 11, the user who reserved the song picks up microphone 19 and sings karaoke. When the karaoke is to be finished, each of the users A, B, C operates his / her own terminal device 51A, 51B, or 51C to release the connection between the terminal device 51A, 51B, or 51C and the karaoke device 11.

[0026] 3 shows the processes performed by the karaoke device 11 in such a series of karaoke flows, i.e., the processes when each of the terminal devices 51A, 51B, 51C is connected to the karaoke device 11, the processes when reserving a song, the processes when playing a song, and the processes when each of the terminal devices 51A, 51B, 51C is disconnected from the karaoke device 11. The processes performed by the karaoke device 11 will be specifically described below with reference to FIG. 3 etc.

[0027] [Connection process] First, a description will be given of the process when each of the terminal devices 51A, 51B, 51C is connected to the karaoke device 11. First, the karaoke device 11 establishes a connection (pairing) between the karaoke device 11 and the terminal device 51A in response to, for example, the operation of the terminal device 51A and the remote control device 18 by the user A (step S1 in FIG. 3). The flow of connection between the karaoke device 11 and the terminal device 51A is generally as follows.

[0028] In the karaoke room, the user A first operates his / her terminal device 51A to start a remote control application. Next, the user operates the touch panel of the remote control device 18 to select an operation item for connecting the terminal device to the karaoke device 11 from among a plurality of operation items displayed on the screen of the display device of the remote control device 18. When the user selects this operation item, a two-dimensional barcode is displayed on the screen of the display device of the remote control device 18. This two-dimensional barcode includes karaoke device identification information and communication address information of the server device 41. The karaoke device identification information is information for identifying the karaoke device 11. The communication address information of the server device 41 is a URL (Uniform Resource Locator) or a global IP address assigned to the server device 41. The user A causes the terminal device 51A to read this two-dimensional barcode with the camera 57 of the terminal device 51A. The terminal device 51A decodes the read two-dimensional barcode and acquires the karaoke device identification information and the communication address information of the server device 41. Next, the terminal device 51A connects to the server device 41 using the communication address of the server device 41 obtained from the two-dimensional barcode. Here, the storage unit 53 of the terminal device 51A stores terminal device identification information for identifying the terminal device 51A. The terminal device 51A transmits this terminal device identification information and the karaoke device identification information obtained from the two-dimensional barcode to the server device 41. The server device 41 identifies the karaoke device 11 based on the karaoke device identification information transmitted from the terminal device 51A, and transmits the terminal device identification information transmitted from the terminal device 51A to the karaoke device 11. The karaoke device 11 receives the terminal device identification information transmitted from the server device 41 and stores it in the storage unit 13. By the karaoke device 11 acquiring the terminal device identification information of the terminal device 51A in this way, the karaoke device 11 becomes able to communicate with the terminal device 51A via the server device 41, and a connection between the karaoke device 11 and the terminal device 51A is essentially established.

[0029] After the connection between the karaoke device 11 and the terminal device 51A is thus established, the image data communication unit 32 of the karaoke device 11 transmits an image data transmission request command, which is a command requesting the transmission of image data, to the terminal device 51A. In response to this, the terminal device 51A transmits the image data stored in the storage unit 53 of the terminal device 51A to the karaoke device 11. Then, the image data communication unit 32 of the karaoke device 11 receives the image data transmitted from the terminal device 51A (step S2).

[0030] Various image data are stored in the storage unit 53 of the terminal device 51A, such as image data generated by user A taking a picture with the camera 57 of the terminal device 51A, image data downloaded by user A and published on the Internet, image data attached to an e-mail received by user A, etc. In step S2, the image data communication unit 32 of the karaoke device 11 receives such image data from the terminal device 51A. Also, if multiple image data are stored in the storage unit 53 of the terminal device 51A, the image data communication unit 32 receives the multiple image data from the terminal device 51A. Note that an image includes a video, and image data includes video data.

[0031] After transmitting the image data to the karaoke device 11, the terminal device 51A displays a login screen on the screen of the display device 56 of the terminal device 51A and requests the user A to log in. The user A inputs his / her user identification information (user ID) and password. The terminal device 51A stores the user identification information input by the user A in the storage unit 53. The terminal device 51A also transmits the user identification information and password input by the user A to the karaoke device 11. The karaoke device 11 then receives the user identification information and password transmitted from the terminal device 51A (step S3). Next, the login processing unit 33 of the karaoke device 11 determines whether the user A is a registered user based on the received user identification information and password, and permits the user A to log in to the karaoke device 11 if the user A is a registered user.

[0032] If user A is permitted to log in to the karaoke device 11, the association forming unit 34 of the karaoke device 11 associates the image data received in step S2 with the user identification information received in step S3 (step S4). As a result, the image data transmitted from the terminal device 51A is associated with the user identification information of user A.

[0033] Next, the association forming unit 34 stores the image data and the user identification information associated in this way in the storage unit 13 (step S5).

[0034] Similarly, when the karaoke device 11 establishes a connection between the karaoke device 11 and the terminal device 51B in response to the operation of the terminal device 51B and the remote control device 18 by the user B, the karaoke device 11 receives the image data transmitted from the terminal device 51B, and then receives the user identification information and password transmitted from the terminal device 51B. If the user B is permitted to log in to the karaoke device 11, the karaoke device 11 associates the image data transmitted from the terminal device 51B with the user identification information of the user B transmitted from the terminal device 51B, and stores the associated image data and user identification information in the storage unit 13. The karaoke device 11 also performs a similar process when the karaoke device 11 establishes a connection between the karaoke device 11 and the terminal device 51C in response to the operation of the terminal device 51C and the remote control device 18 by the user C.

[0035] Fig. 4 shows an example of image data and user identification information stored in the storage unit 13 of the karaoke device 11 in association with each other by the processing of steps S1 to S5 in Fig. 3. As shown in Fig. 4, the image data IMG11, IMG12, and IMG13 transmitted from the terminal device 51A are each associated with the user identification information USR01 of the user A. Furthermore, the image data IMG21 and IMG22 transmitted from the terminal device 51B are each associated with the user identification information USR02 of the user B. Furthermore, the image data IMG31 and IMG32 transmitted from the terminal device 51C are each associated with the user identification information USR03 of the user C.

[0036] [Processing when reserving a song] Next, the process of reserving a song in the karaoke device 11 will be described. The remote control application installed in each of the terminal devices 51A, 51B, 51C has a function of searching for a song based on the singer name or song title, etc., and a function of reserving the karaoke performance of the song selected by the user to the karaoke device 11. For example, when user A wants to sing karaoke, user A operates the remote control application of the terminal device 51A to search for songs and reserves a song selected from the searched songs. In response to this operation by user A, the terminal device 51A transmits song identification information of the song selected by user A together with the user identification information of user A to the karaoke device 11. Then, the karaoke device 11 receives the song identification information and user identification information transmitted from the terminal device 51A (step S11 in FIG. 3).

[0037] Next, the reservation unit 35 of the karaoke device 11 associates the song identification information and the user identification information received in step S11 with each other and registers them in a queue (step S12). The queue is a first-in, first-out information arrangement (queue) in which the song identification information of the reserved songs and the user identification information associated with the song identification information are arranged in the order of reservation. Registering in the queue means adding to the queue. The queue is stored in the storage unit 13 of the karaoke device 11.

[0038] Similarly, when user B wants to sing karaoke, he operates the remote control application of terminal device 51B to search for songs and reserve a song selected from the searched songs. Karaoke device 11 receives the song identification information and user identification information transmitted from terminal device 51B in response to the operation of user B, associates the song identification information with the user identification information, and registers them in the queue. Similarly, when user C operates the remote control application of terminal device 51C to search for songs and reserves a song selected from the searched songs, karaoke device 11 performs the same process.

[0039] Fig. 5 shows an example of song identification information and user identification information that are associated with each other and registered in the queue by the processing of steps S11 and S12 in Fig. 3. As shown in Fig. 5, song identification information SNG09 of a song selected by user A and user identification information USR01 of user A are associated with each other. Furthermore, song identification information SNG05 of a song selected by user B and user identification information USR02 of user B are associated with each other. Furthermore, song identification information SNG12 of a song selected by user C and user identification information USR03 of user C are associated with each other.

[0040] [Processing during music performance] Next, a process of playing a song in the karaoke device 11 will be described. The playing unit 36 ​​of the karaoke device 11 performs karaoke of the songs corresponding to the song identification information registered in the queue in the order of reservation. For example, as shown in Fig. 5, when song identification information SNG09, SNG05, and SNG12 of songs selected by users A, B, and C, respectively, are registered in the queue in this order, the playing unit 36 ​​first starts karaoke performance of the song selected by user A, i.e., the song corresponding to song identification information SNG09 (step S21 in Fig. 3).

[0041] Next, the image data specification unit 37 of the karaoke device 11 specifies image data associated with the user identification information corresponding to the song identification information of the song for which karaoke performance has started (step S22). Specifically, the image data specification unit 37 first refers to the queue and specifies the user identification information associated with the song identification information SNG09 of the song selected by user A, i.e., the user identification information USR01 of user A. Next, the image data specification unit 37 specifies the image data IMG11, IMG12, and IMG13 associated with the user identification information USR01 from among a plurality of image data items associated with the user identification information and stored in the storage unit 13 as shown in FIG.

[0042] Next, the display control unit 38 of the karaoke device 11 displays an image corresponding to the image data identified by the image data identification unit 37 on the display device 21 (step S23). The image corresponding to the image data identified by the image data identification unit 37 is displayed large as a background image, filling the entire screen of the display device 21. The image corresponding to the image data identified by the image data identification unit 37 is also displayed on the display device 21 until the karaoke performance of the song currently being performed is completed.

[0043] Furthermore, when the image data specification unit 37 specifies a plurality of image data, the display control unit 38 switches between a plurality of images corresponding to the plurality of image data and displays them on the display device 21. In this case, the order of displaying the images may be in the order of the earliest image capture date / time or the earliest creation date / time, or may be random. The image capture date / time and the creation date / time are described as metadata in the image data. The interval for switching the image display may be calculated by dividing the performance time of the music by the number of images, or may be a fixed interval set in advance. For example, if the image display order is in the order of the earliest image capture date / time and the interval for switching the image display is a fixed interval of 30 seconds, three images corresponding to the image data IMG11, IMG12, and IMG13 are repeatedly displayed on the display device 21 in the order of the earliest image capture date / time at 30-second intervals while the karaoke performance of the music corresponding to the music identification information SNG09 is being performed.

[0044] When performing karaoke performance of songs based on the queue shown in FIG. 5, after the karaoke performance of the song corresponding to the song identification information SNG09 is completed (step S24: YES), the performance unit 36 ​​starts the karaoke performance of the song corresponding to the song identification information SNG05 selected by the user B. Then, the image data specification unit 37 specifies the image data IMG21 and IMG22 corresponding to the user identification information USR02 corresponding to the song identification information SNG05. Then, the display control unit 38 displays two images corresponding to the image data IMG21 and IMG22, respectively, on the display device 21 while switching between them. After the karaoke performance of the song corresponding to the song identification information SNG05 is completed, the performance unit 36 ​​starts the karaoke performance of the song corresponding to the song identification information SNG12 selected by the user C. Then, the image data specification unit 37 specifies the image data IMG31 and IMG32 corresponding to the user identification information USR03 corresponding to the song identification information SNG12. Next, the display control unit 38 displays on the display device 21 two images corresponding to these image data IMG31 and IMG32, respectively, while switching between them.

[0045] [Processing when disconnected] Next, a process for disconnecting the terminal devices 51A, 51B, 51C from the karaoke device 11 will be described. When finishing karaoke, user A uses the terminal device 51A to perform an operation to disconnect (pair) the terminal device 51A from the karaoke device 11 (step S31). Similarly, user B uses the terminal device 51B to perform an operation to disconnect the terminal device 51B from the karaoke device 11. User C also uses the terminal device 51C to perform an operation to disconnect the terminal device 51C from the karaoke device 11. As a result, the connections between the terminal devices 51A, 51B, 51C and the server device 41 are cut off, and the terminal devices 51A, 51B, 51C are unable to communicate with the karaoke device 11.

[0046] As described above, when a connection is established between the karaoke device 11 and each of the terminal devices 51A, 51B, 51C, the karaoke device 11 in the first embodiment of the present invention stores in the memory unit 13 a plurality of image data transmitted from the terminal devices 51A, 51B, and 51C, respectively, in association with the user identification information of the users A, B, and C, respectively, and registers in a queue the song identification information of the songs selected by the users A, B, and C, respectively, in association with the user identification information of the users A, B, and C, respectively, and, when performing karaoke of the song corresponding to the song identification information registered in the queue, identifies from the plurality of image data stored in the memory unit 13 the image data associated with the user identification information corresponding to the song identification information registered in the queue, and displays an image corresponding to the identified image data on the display device 21. Thus, during the karaoke performance of the song selected by user A, an image corresponding to the image data transmitted from terminal device 51A can be displayed on display device 21, during the karaoke performance of the song selected by user B, an image corresponding to the image data transmitted from terminal device 51B can be displayed on display device 21, and during the karaoke performance of the song selected by user C, an image corresponding to the image data transmitted from terminal device 51C can be displayed on display device 21. That is, if the image data of images photographed by users A, B, and C with terminal devices 51A, 51B, and 51C are stored in storage units 53 of terminal devices 51A, 51B, and 51C, respectively, the image photographed by user A with terminal device 51A can be displayed as a background image when user A sings karaoke, the image photographed by user B with terminal device 51B can be displayed as a background image when user B sings karaoke, and the image photographed by user C with terminal device 51C can be displayed as a background image when user C sings karaoke. In this way, the karaoke device 11 can automatically switch the display of the image taken by the user on the display device 21 every time the song being performed by karaoke is changed. Also, the timing at which the user sings karaoke and the timing at which the image taken by the user is displayed on the display device 21 as a background image can be automatically synchronized.

[0047] Moreover, when the karaoke device 11 is connected to each of the terminal devices 51A, 51B, and 51C, the karaoke device 11 acquires a plurality of image data from each of the terminal devices 51A, 51B, and 51C and stores them in the storage unit 13. The stored plurality of image data are automatically switched and displayed in synchronization with the switching of the karaoke performance of the music piece, so that the users A, B, and C do not need to manually operate the terminal devices 51A, 51B, or 51C to transmit the image data to the karaoke device 11 one by one. In this way, the karaoke device 11 of this embodiment can easily display a plurality of images taken by the users A, B, and C using the terminal devices 51A, 51B, and 51C as background images while the users A, B, and C are singing karaoke, while switching between them. Therefore, the users A, B, and C can easily enjoy singing karaoke to each other and showing each other the images they have taken.

[0048] In the above first embodiment, the terminal devices 51A, 51B, 51C are connected to the karaoke device 11 via the server device 41, but the terminal devices 51A, 51B, 51C may be connected directly to the karaoke device 11 without the server device 41. In this case, the information security measures of each karaoke device 11 are strengthened.

[0049] In addition, in the above first embodiment, an example was given in which the information required to connect each terminal device 51A, 51B, 51C to the karaoke device 11 is provided to each terminal device 51A, 51B, 51C using a two-dimensional barcode, but the information required to connect each terminal device 51A, 51B, 51C to the karaoke device 11 may also be provided to each terminal device 51A, 51B, 51C using short-range wireless communication such as NFC (Near Field Communication).

[0050] In addition, in the above first embodiment, image data is automatically transmitted from the terminal device to the karaoke device 11 immediately after a connection between the karaoke device 11 and the terminal device is established, but image data may also be automatically transmitted from the terminal device to the karaoke device 11 after a user logs in to the karaoke device 11.

[0051] Second embodiment Fig. 6 shows a karaoke device 61 according to a second embodiment of the present invention. In the karaoke device 61 shown in Fig. 6, the same components as those of the karaoke device 11 according to the first embodiment shown in Fig. 2 are given the same reference numerals, and their description will be omitted. As shown in Fig. 6, the control unit 62 of the karaoke device 61 according to the second embodiment has an association analysis unit 63 that analyzes associations between lyrics of a song and images. The association analysis unit 63 is realized, for example, by the control unit 62 reading and executing a program stored in the storage unit 13.

[0052] Fig. 7 shows the process when each of the terminal devices 51A, 51B, 51C is connected to the karaoke device 61, the process when a song is reserved at the karaoke device 61, the process when a song is played at the karaoke device 61, and the process when each of the terminal devices 51A, 51B, 51C is disconnected from the karaoke device 61. In the process of the karaoke device 61 shown in Fig. 7, steps that are the same as those in the process of the karaoke device 11 of the first embodiment shown in Fig. 3 are given the same reference numerals, and their explanations will be omitted or simplified.

[0053] As shown in FIG. 7, in the process of connecting each of the terminal devices 51A, 51B, 51C to the karaoke device 61, when the karaoke device 61 establishes a connection between the karaoke device 61 and the terminal device 51A in response to the operation of the terminal device 51A and the remote control device 18 by the user A (step S1), the karaoke device 61 receives image data transmitted from the terminal device 51A (step S2), and then receives the user identification information and password transmitted from the terminal device 51A (step S3). If the user A is permitted to log in to the karaoke device 61, the image data transmitted from the terminal device 51A is associated with the user identification information of the user A (step S4), and the associated image data and user identification information are stored in the memory unit 13 (step S5).

[0054] Next, the association analysis unit 63 of the karaoke device 61 determines image keywords for the image data stored in the storage unit 13 in step S5 (step S41). When a plurality of image data are received in step S2 and stored in the storage unit 13 in step S5, the association analysis unit 63 determines image keywords for each of the stored image data.

[0055] An image keyword is a word that represents something (e.g., a person, an object, a landscape, etc.) that is reflected or depicted in an image corresponding to image data when the image is viewed as a whole. Specifically, if the image corresponding to image data is a photograph, the image keyword is a word that represents the subject of the photograph. For example, if the object reflected in the image corresponding to image data is the sea, the image keyword is "sea". The association analysis unit 63 recognizes things reflected or depicted in the image corresponding to the image data by performing an image recognition process on the image data received in step S2, and determines an image keyword for the image data. In addition, if the image data received in step S2 includes the title of the image as metadata, the image keyword may be determined based on the title. For the process of determining the image keyword, a well-known technique such as that described in JP-A-2010-218227 can be used.

[0056] After determining the image keyword for the image data, the association analysis unit 63 adds the image keyword for the image data to the image data stored in the storage unit 13 in step S5 (step S42).

[0057] Similarly, when the karaoke device 11 establishes a connection between the karaoke device 11 and the terminal device 51B in response to the operation of the terminal device 51B and the remote control device 18 by the user B, the karaoke device 11 receives the image data transmitted from the terminal device 51B, and then receives the user identification information and password transmitted from the terminal device 51B. If the user B is permitted to log in to the karaoke device 11, the karaoke device 11 associates the image data transmitted from the terminal device 51B with the user identification information of the user B, stores the associated image data and user identification information in the storage unit 13, determines an image keyword for the image data stored in the storage unit 13, and adds the determined image keyword to the image data. The karaoke device 11 also performs a similar process when the karaoke device 11 establishes a connection between the karaoke device 11 and the terminal device 51C in response to the operation of the terminal device 51C and the remote control device 18 by the user C.

[0058] Fig. 8 shows an example of image keywords added to image data and user identification information that are associated with each other and stored in storage unit 13 by the processing of steps S1 to S5, S41, and S42 in Fig. 7. In Fig. 8, for example, the image keyword "sea" is added to image data IMG11 associated with user identification information USR01 of user A. The image keyword "cat" is added to image data IMG21 associated with user identification information USR02 of user B. The image keyword "moon" is added to image data IMG31 associated with user identification information USR03 of user C.

[0059] Also, as shown in FIG. 7, in the process of playing a song in the karaoke device 61, for example, it is assumed that the song identification information SNG09 of the song selected by the user A is associated with the user identification information USR01 of the user A and registered in the queue (see FIG. 5), and the performance unit 36 ​​of the karaoke device 61 starts karaoke performance of this song (step S21). In this case, the image data specification unit 37 of the karaoke device 61 specifies image data associated with the user identification information corresponding to the song identification information of the song whose karaoke performance has started (step S22). Specifically, the image data specification unit 37 first refers to the queue and specifies the user identification information USR01 corresponding to the song identification information SNG09 of the song whose karaoke performance has started. Next, the image data specification unit 37 specifies the image data IMG11, IMG12, and IMG13 associated with the user identification information USR01 from among a plurality of image data associated with the user identification information and stored in the storage unit 13 as shown in FIG. 8 (step S22).

[0060] Next, the relation analysis unit 63 of the karaoke device 61 determines lyrics keywords of the lyrics of the song for which karaoke performance has started (step S51).

[0061] A lyric keyword is a word that is frequently used in the lyrics of a song. For example, a lyric keyword is a word that is most frequently used among words included in the lyrics of a song, three words that are first, second, and third when the words included in the lyrics of a song are ranked in order of frequency of use, or a word that is used a predetermined number of times or more among words included in the lyrics of a song. In this embodiment, the association analysis unit 63 determines the word that is most frequently used among words included in the lyrics of a song as a lyric keyword. For example, if the word that is most frequently used among words included in the lyrics of a song is "sea", the lyric keyword is "sea". Note that the lyric keywords for the lyrics of each song prepared in the karaoke system 1 may be determined in advance, and the lyric keywords may be included in the lyric data in advance. In this way, the association analysis unit 63 can determine the lyric keywords simply by reading the lyric keywords included in the lyric data.

[0062] Next, the association analysis unit 63 selects image data of an image related to the lyrics of the song from which the karaoke performance has started from among the image data specified by the image data specification unit 37, based on the lyrics keywords of the lyrics of the song from which the karaoke performance has started and the image keywords added to the image data specified by the image data specification unit 37 (step S52). Specifically, the association analysis unit 63 compares the lyrics keywords of the lyrics of the song from which the karaoke performance has started with the image keywords added to the image data specified by the image data specification unit 37, and determines whether they match or are similar. Then, when the lyrics keywords of the lyrics of the song from which the karaoke performance has started and the image keywords added to the image data specified by the image data specification unit 37 match or are similar, the association analysis unit 63 determines that the lyrics of the song and the image corresponding to the image data are related, and selects the image data.

[0063] For example, as shown in FIG. 8, the image keyword added to image data IMG11 is "sea", the image keyword added to image data IMG12 is "coast", and the image keyword added to image data IMG13 is "bon dance". Also, the lyrics keyword of the song from which karaoke performance has started, that is, the song selected by user A, is "sea". The image keyword "sea" matches the lyrics keyword "sea". Also, the image keyword "coast" is similar to the lyrics keyword "sea". On the other hand, the image keyword "bon dance" does not match and is not similar to the lyrics keyword "sea". In this case, the association analysis unit 63 selects image data IMG11 and image data IMG12 from the image data IMG11, IMG12, and IMG13 identified by the image data identification unit 37 as image data of images related to the lyrics of the song from which karaoke performance has started.

[0064] Next, the display control unit 38 of the karaoke device 61 displays an image corresponding to the image data selected by the association analysis unit 63 as a background image on the display device 21 connected to the karaoke device 61 (step S53). When the image data selected by the association analysis unit 63 are image data IMG11 and image data IMG12, the display control unit 38 displays on the display device 21 an image corresponding to the image data IMG11 and an image corresponding to the image data IMG12 while switching between them.

[0065] In addition, if image data of an image related to the lyrics of the song for which karaoke performance has started is not present in the image data identified by the image data identification unit 37, the display control unit 38 of the karaoke device 61 will display, as a background image on the display device 21, images corresponding to all the image data identified by the image data identification unit 37, switching between them.

[0066] The karaoke device 61 of the second embodiment of the present invention can also provide the same operational effects as the karaoke device 11 of the first embodiment of the present invention. Furthermore, the karaoke device 61 of the second embodiment can display, as a background image, an image related to the lyrics of the song that the user is singing karaoke, among images taken by the user with the terminal device while the user is singing karaoke, on the display device 21. By displaying an image related to the lyrics of the song, the atmosphere of the song and the message of the lyrics can be easily conveyed to the user who is listening to the karaoke singing.

[0067] In the above second embodiment, an example was given of a case where the image keyword of the image data is determined when the karaoke device 61 receives the image data from the terminal device, but it is also possible to determine an image keyword of the image data associated with the user identification information corresponding to the song identification information of the song when the performance of the song begins.

[0068] (Third embodiment) FIG. 9 shows a karaoke device 71 according to a third embodiment of the present invention. In the karaoke device 71 shown in FIG. 9, the same components as those of the karaoke device 11 according to the first embodiment shown in FIG. 2 are given the same reference numerals, and their description will be omitted. As shown in FIG. 9, the control unit 72 of the karaoke device 71 according to the third embodiment includes a first image data specification unit 37 and a second image data specification unit 73. The first image data specification unit 37 is the same as the image data specification unit 37 of the karaoke device 11 according to the first embodiment (the first image data specification unit 37 is given the same reference numeral as the image data specification unit 37 of the karaoke device 11 according to the first embodiment). The second image data specification unit 73 photographs a user singing karaoke with the camera 22, specifies face image data that matches the image of the user photographed, and specifies image data associated with user identification information corresponding to the specified face image data. The second image data specification unit 73 is realized, for example, by the control unit 72 reading and executing a program stored in the storage unit 13.

[0069] Further, a plurality of user characteristic data each including information on the appearance of a plurality of users is stored in the storage unit 13 of the karaoke device 71 in association with the user identification information of the plurality of users. Specifically, as shown in Fig. 10, face image data CHR01, CHR02 and CHR03 which are images of the faces of users A, B and C are stored in the storage unit 13 of the karaoke device 71 in association with the user identification information USR01, USR02 and USR03 of users A, B and C, respectively.

[0070] Fig. 11 shows the process when each of the terminal devices 51A, 51B, 51C is connected to the karaoke device 71, the process when a song is reserved at the karaoke device 71, the process when a song is played at the karaoke device 71, and the process when each of the terminal devices 51A, 51B, 51C is disconnected from the karaoke device 71. In the process of the karaoke device 71 shown in Fig. 11, steps having the same content as steps in the process of the karaoke device 11 of the first embodiment shown in Fig. 3 are given the same reference numerals, and their explanation will be omitted or simplified.

[0071] In Fig. 11, a process is performed when each of the terminal devices 51A, 51B, and 51C is connected to the karaoke device 71, and a plurality of image data transmitted from the terminal devices 51A, 51B, and 51C to the karaoke device 71 are stored in the storage unit 13 of the karaoke device 71 in association with the user identification information of the users A, B, and C, respectively, as shown in Fig. 4. Also, a process is performed when reserving a song in the karaoke device 71, and the song identification information of the songs selected by the users A, B, and C are registered in a queue in association with the user identification information of the users A, B, and C, respectively, as shown in Fig. 5. In this state, a process is started when the song is played in the karaoke device 71, and the performance unit 36 ​​of the karaoke device 71 starts karaoke performance of the song corresponding to the song identification information SNG09 selected by the user A (step S21). In this case, the first image data specification unit 37 of the karaoke device 71 specifies image data associated with the user identification information corresponding to the song identification information of the song for which karaoke performance has started (step S22). Specifically, the first image data specification unit 37 first refers to the queue shown in Fig. 5 and specifies the user identification information USR01 corresponding to the song identification information SNG09 of the song for which karaoke performance has started, and then specifies the image data IMG11, IMG12, and IMG13 corresponding to the user identification information USR01 from among a plurality of image data associated with the user identification information and stored in the storage unit 13 as shown in Fig. 4 (step S22). Next, the display control unit 38 of the karaoke device 71 switches between images corresponding to the image data IMG11, IMG12, and IMG13 specified by the first image data specification unit 37 and displays them on the display device 21 (step S23).

[0072] While the image data IMG11, IMG12, and IMG13 identified by the first image data identification unit 37 in step S22 are being switched and displayed, the second image data identification unit 73 of the karaoke device 71 determines whether the user singing the karaoke has changed (step S61).

[0073] The second image data specification unit 73 judges whether the user who sings karaoke has changed as follows. First, the second image data specification unit 73 specifies face image data associated with user identification information corresponding to the music identification information of the music currently being performed karaoke from among a plurality of face image data stored in the storage unit 13 as shown in FIG. 10. Next, the second image data specification unit 73 controls the camera 22 connected to the karaoke device 71 to capture an image of the entire area of ​​the karaoke room with the camera 22. For example, the camera 22 has an ultra-wide-angle lens and can capture an image of the entire area of ​​the karaoke room. The camera 22 may be installed on a movable pan head and the orientation of the camera 22 may be changed by the pan head to capture an image of the entire area of ​​the karaoke room. Next, the second image data specification unit 73 recognizes a user who sings karaoke among a plurality of users in the karaoke room based on the captured image obtained by the camera 22. Specifically, the second image data specification unit 73 recognizes a person who holds the microphone 19 close to his / her mouth based on the captured image obtained by the camera 22 and judges that person to be a user who sings karaoke. Next, the second image data specification unit 73 recognizes the face of the user singing karaoke based on the captured image obtained by the camera 22, and specifies facial image data that matches the recognized user's face from among the multiple facial image data stored in the storage unit 13. Next, the second image data specification unit 73 compares the facial image data associated with the user identification information corresponding to the song identification information of the song currently being performed karaoke with the facial image data that matches the face of the user singing karaoke recognized based on the captured image, and if the two are different, it determines that the user singing karaoke has changed, whereas if the two are identical, it determines that the user singing karaoke has not changed.

[0074] If the user singing karaoke has changed (step S61: YES), the second image data identification unit 73 identifies image data associated with user identification information corresponding to facial image data that matches the face of the user singing karaoke recognized based on the captured image from among the multiple image data stored in the memory unit 13, as shown in Figure 4 (step S62).

[0075] For example, if the user singing karaoke is changed from user A to user B during karaoke performance of a song selected by user A, the second image data specification unit 73 first specifies face image data CHR01 associated with user A's user identification information USR01 corresponding to the song identification information SNG09 of the song currently being karaoke performed. Next, the second image data specification unit 73 recognizes the face of user B singing karaoke based on the image captured by the camera 22, and specifies face image data CHR02 that matches the face of user B. Then, since these two specified face image data are different from each other, the second image data specification unit 73 determines that the user singing karaoke has changed. In this case, the second image data specification unit 73 specifies image data IMG21 and IMG22 associated with user B's user identification information USR02 corresponding to face image data CHR02.

[0076] Next, the display control unit 38 of the karaoke device 71 displays an image corresponding to the image data identified by the second image data identification unit 73 as a background image on the display device 21 connected to the karaoke device 71 during karaoke performance of the song whose karaoke performance began in step S21 (step S24: NO, step S23).

[0077] For example, if the user singing karaoke changes from user A to user B during the karaoke performance of a song selected by user A, the images displayed on display device 21 during the performance of the song will switch from images corresponding to image data IMG11, IMG12 and IMG13, respectively (for example, images taken by user A with terminal device 51A) to images corresponding to image data IMG21 and IMG22, respectively (for example, images taken by user B with terminal device 51B).

[0078] On the other hand, when user A continues to sing the karaoke of the song he / she selected from the beginning to the end of the karaoke performance of the song, the image data IMG11, IMG12, and IMG13 are displayed in a switching manner from the beginning to the end of the karaoke performance of the song. On the other hand, when the user singing the karaoke changes from user A to user B during the karaoke performance of the song selected by user A, and then from user B to user C, the images displayed on the display device 21 are switched from the images corresponding to the image data IMG11, IMG12, and IMG13, respectively, to images corresponding to the image data IMG21 and IMG22, respectively, and then from the images corresponding to the image data IMG21 and IMG22, respectively, to images corresponding to the image data IMG31 and IMG32, respectively.

[0079] The karaoke device 71 of the third embodiment of the present invention can also provide the same effects as the karaoke device 11 of the first embodiment of the present invention. Furthermore, according to the karaoke device 71 of the third embodiment, when the user singing karaoke is changed from user A to user B during karaoke performance of a song, the background image displayed on the display device 21 can be automatically switched from the image taken by user A with the terminal device 51A to the image taken by user B with the terminal device 51B. As a result, when the user who reserved the song is different from the user who is actually singing the karaoke of the song, the image taken by the user who is actually singing the karaoke can be displayed as the background image.

[0080] In the third embodiment, when a song starts to be played, image data associated with user identification information corresponding to the song identification information of the song is specified and displayed, and when the user singing karaoke is changed, the face of the new user is recognized, and image data associated with user identification information corresponding to face image data matching the recognized face is specified and displayed. However, the present invention is not limited to this. When a song starts to be played, the face of the user singing karaoke of the song may be recognized, and image data associated with user identification information corresponding to face image data matching the recognized face may be specified and displayed.

[0081] In the above third embodiment, facial image data is used as the user characteristic data, but image data of an image of the user's body, clothes, etc. other than the face may be used as the user characteristic data. Also, a user singing karaoke may be recognized based on the characteristics of the user's voice collected by the microphone 19.

[0082] Furthermore, the present invention can be modified as appropriate within the scope of the claims and the gist or concept of the invention that can be read from the entire specification, and karaoke devices involving such modifications are also included in the technical concept of the present invention.
