Summary of the Invention

Problems to be Solved by the Invention

[0005] Here, when using a karaoke device in an open place such as various events, there is a possibility that an unspecified number of viewers will view the background image. Therefore, for the purpose of preventing the specific image from being secretly photographed by the viewers, the karaoke operator needs to perform the setting of not displaying the specific image before lending out the karaoke device.

[0006] An object of the present invention is to provide a karaoke device capable of omitting the trouble of performing the display setting of the background image.

Means for Solving the Problems

[0007] One invention for achieving the above objective is a karaoke device equipped with GPS, comprising: an information storage unit that stores event information including the date, start time, end time, and location of an event; an identification unit that identifies the current location of the karaoke device based on location information acquired by the GPS; and a setting unit that, when the identified current location of the karaoke device matches the location included in the event information of a certain event, when the date on which the current location was identified matches the date included in the event information of the certain event, when a song is selected in the karaoke device between the start time and end time included in the event information of the certain event, and when the background video data of the selected song satisfies predetermined conditions, sets a special mode that changes the display manner of the background video, instead of a normal mode that displays the background video corresponding to the background video data of the song as is. Other features of the present invention will be revealed in the specification and drawings described below. [Effects of the Invention]

[0008] According to the present invention, the effort required to set the display settings for the background image can be eliminated. [Brief explanation of the drawing]

[0009] [Figure 1] This is a diagram showing a karaoke device according to an embodiment. [Figure 2] This is a diagram showing a karaoke machine according to an embodiment. [Figure 3] This figure shows an example of background video data associated with each song according to this embodiment. [Figure 4] This is a flowchart showing the processing of the karaoke apparatus according to the embodiment. [Modes for carrying out the invention]

[0010] <Embodiment> A karaoke apparatus according to this embodiment will be described with reference to Figures 1 to 4.

[0011] ==Karaoke Equipment== Karaoke device K is a device for playing karaoke songs and for users to sing karaoke. As shown in Figure 1, karaoke device K comprises a karaoke unit 10, speakers 20, a display device 30, a microphone 40, a remote control device 50, and a GPS (Global Positioning System) 60.

[0012] The karaoke unit 10 performs various controls related to karaoke performance and singing, such as controlling the karaoke performance of selected songs, controlling the display of lyrics and background images, and processing audio signals input through the microphone 40. The speaker 20 is configured to emit sound based on the sound signal emitted from the karaoke unit 10. The display device 30 is configured to display videos and images on the screen based on signals from the karaoke unit 10. The microphone 40 is configured to convert the voice emitted by the user into an analog audio signal and input it to the karaoke unit 10. The remote control device 50 is a device for performing various operations on the karaoke unit 10. The GPS 60 is a system for acquiring the location information of the karaoke device K. The location information is acquired, for example, as coordinate information. The process of acquiring location information by the GPS 60 is the same as that of a general GPS.

[0013] As shown in Figure 2, the karaoke unit 10 according to this embodiment includes a storage means 10a, a communication means 10b, an input means 10c, a performance means 10d, and a control means 10e. Each component is connected to bus B via an interface (not shown).

[0014] [Storage means] The storage means 10a is a large-capacity storage device for storing various types of data. The storage means 10a stores music data.

[0015] Music data includes song identification information to distinguish each individual song. This song identification information is unique to each song, such as a song ID. Music data also includes accompaniment data, reference data, etc.

[0016] The accompaniment data is the data that serves as the basis for the karaoke performance sound. The reference data is the data that indicates the singing melody of the music played in karaoke and is used when scoring the karaoke singing by the user.

[0017] In addition, the storage means 10a stores lyric telop data for causing the display device 30 or the like to display the lyrics corresponding to each music, background video data for causing the display device 30 or the like to display the background video during karaoke performance, performance time data indicating the karaoke performance time for each music, and attribute information of the music (information regarding the music such as the singer's name, the names of the lyricist and composer, the genre, etc.).

[0018] In the present embodiment, the background video indicated by the background video data is a general-purpose video or a specific video. The general-purpose video is a video for which it is not necessary to pay a license fee to the copyright owner, such as a video owned by the karaoke operator or a general scenery video. The specific video is a video for which it is necessary to pay a license fee to the copyright owner, such as a promotional video or a live video in which the artist or the like appears. For one music, the background video data corresponding to the general-purpose video or the specific video is associated with the video flag. The video flag is an identifier for distinguishing between a general-purpose video and a specific video. Further, in the present embodiment, the storage means 10a stores at least one piece of background video data corresponding to a general-purpose video that is not associated with a specific music.

[0019] FIG. 3 shows an example of the background video data associated with each music. For example, for music X1 (music ID ***X1), the video flag "1" indicating a specific video and the background video data ID ***SV1 corresponding to the specific video are associated. Also, for music X2 (music ID ***X2), the video flag "1" indicating a specific video and the background video data ID ***SV2 corresponding to the specific video are associated. On the other hand, for music X3 (music ID ***X3), the video flag "0" indicating a general-purpose video and the background video data ID ***GV1 corresponding to the general-purpose video are associated.

[0020] In this embodiment, a part of the storage area of the storage means 10a functions as an information storage unit 100.

[0021] (Information storage unit) The information storage unit 100 stores event information.

[0022] The event information includes the event date, start time, end time, and venue. The event according to this embodiment is an event held in an open place such as outdoors or a public gymnasium, and an event in which an unspecified number of viewers may watch the background video displayed on the karaoke device. The event date is the date (e.g., year, month, and day) on which the event is held. The start time is the time when the event starts or the time when the use of the karaoke device starts. The end time is the time when the event ends or the time when the use of the karaoke device ends. The venue is information indicating the venue or area where the event is held. The venue can be indicated by an address or coordinate information.

[0023] For example, when lending out the karaoke device K for a certain event, the karaoke operator operates the remote control device 50 to input the event date, start time, end time, and venue of a certain event. The remote control device 50 transmits each input information as event information to the karaoke main body 10. The information storage unit 100 stores the event information received from the remote control device 50.

[0024] [Communication means, input means, performance means] The communication means 10b provides an interface for communicating with the remote control device 50. The input means 10c is a configuration for the user to perform various operation inputs. The input means 10c is a button or the like provided on the karaoke main body 10. Alternatively, the remote control device 50 may function as the input means 10c. The performance means 10d performs karaoke performance of music and processing of the voice signal input through the microphone 40 based on the control of the control means 10e. The performance means 10d includes a sound source, a mixer, an amplifier, etc. (none of which are shown).

[0025] [Control means] The control means 10e performs various controls on the karaoke machine K. The control means 10e includes a CPU and memory (neither of which are shown in the figure). The CPU realizes various functions by executing programs stored in the memory.

[0026] In this embodiment, the control means 10e functions as a specific unit 200 and a setting unit 300 when the CPU executes a program stored in memory.

[0027] (Specific part) The identification unit 200 determines the current location of the karaoke machine K based on the location information acquired by the GPS 60.

[0028] For example, a karaoke operator transports the karaoke machine K to the venue where the event is being held, and then turns on the power to the karaoke machine K. The identification unit 200 instructs the GPS 60 to acquire location information. The GPS 60 acquires coordinate information as the location information of the karaoke machine K. The identification unit 200 then applies the coordinate information acquired at this time to an address information table (a table that associates coordinate information with addresses on a map) that is pre-stored in the karaoke machine K, thereby identifying a certain address as the current location of the karaoke machine K.

[0029] The identification unit 200 outputs the current location of the identified karaoke machine K to the setting unit 300.

[0030] (Settings section) The setting unit 300 sets a special mode instead of the normal mode if the current location of the identified karaoke machine K matches the venue included in the event information of a certain event, the date on which the current location was identified matches the date of the event included in the event information of the certain event, a song is selected in the karaoke machine K between the start time and the end time included in the event information of the certain event, and the background video data of the selected song satisfies predetermined conditions.

[0031] When the current location of the karaoke machine K is input from the identification unit 200, the setting unit 300 refers to the venue included in the event information stored in the information storage unit 100. The setting unit 300 checks whether the identified current location of the karaoke machine K matches the venue. For example, if the current location and venue are indicated by an address, the setting unit 300 checks whether the addresses match. A match includes an approximate match. For example, an address match may be an exact match, or it may be an approximate match such as "matching up to the block number" or "matching up to the house number".

[0032] Furthermore, when the current location of the karaoke machine K is input from the identification unit 200, the setting unit 300 refers to the event date included in the event information stored in the information storage unit 100. The setting unit 300 checks whether the date on which the current location was identified matches the event date. The date on which the current location was identified can be determined by the date management function provided by a typical karaoke machine. In other words, the setting unit 300 uses the date management function to determine the date on which the current location was input as the date on which the current location was identified.

[0033] If the current location of the identified karaoke machine K matches the venue, and the date on which the current location was identified matches the date of the event, the setting unit 300 will remain in a waiting state until a song is selected. On the other hand, if the current location of the identified karaoke machine K does not match the venue, or if the date on which the current location was identified does not match the date of the event, the setting unit 300 will not perform any further processing.

[0034] When a song is selected in the karaoke machine K, the setting unit 300 refers to the start time and end time included in the event information stored in the information storage unit 100. The setting unit 300 determines whether the time when the song was selected falls within the period from the start time to the end time. If the time when the song was selected falls within the period from the start time to the end time, the setting unit 300 determines whether the background video data of the selected song meets predetermined conditions. On the other hand, if the time when the song was selected does not fall within the period from the start time to the end time, the setting unit 300 does not perform any further processing.

[0035] The predetermined conditions are those used to determine whether or not to set a special mode. For example, a predetermined condition might be that "a video flag indicating a specific video is associated with the background video data of the selected song."

[0036] Normal mode displays the background video corresponding to the song's background video data as is when displaying background video in sync with karaoke performance. Special mode, on the other hand, does not simply display the background video corresponding to the song's background video data as is, but instead changes the display style of the background video when displaying background video in sync with karaoke performance. In most karaoke machines, normal mode is set as the default setting.

[0037] There are various ways to change the display mode of the background video. For example, the setting unit 300 can set a special mode to display a background video different from the background video corresponding to the background video data of the selected song. Alternatively, the setting unit 300 can set a special mode to not display any background video. In other words, changing the display mode of the background video includes not only displaying a different background video, but also not displaying any background video at all. A different background video is, for example, a general-purpose video that corresponds to background video data stored in the storage means 10a and is not associated with a specific song, other than a specific video.

[0038] If the setting unit 300 determines that the background video data of the selected song meets predetermined conditions, it sets a special mode. On the other hand, if the setting unit 300 determines that the background video data of the selected song does not meet predetermined conditions, it maintains the normal mode.

[0039] Subsequently, the karaoke device K begins playing the selected song. If a special mode is set, the karaoke device K changes the display mode of the background video corresponding to the background video data of the selected song and displays it on the display device 30, etc.

[0040] ==Regarding the operation of karaoke machine K== Next, a specific example of the operation of the karaoke device K in this embodiment will be described with reference to Figure 4. Figure 4 is a flowchart showing an example of the operation of the karaoke device K. In this example, it is assumed that the storage means 10a stores the data shown in Figure 3. It is also assumed that the karaoke device K is set to the above-mentioned normal mode by default. Furthermore, the predetermined condition is that "a video flag indicating a specific video is associated with the background video data of the selected song."

[0041] The identification unit 200 determines the current location of the karaoke machine K based on the location information acquired by the GPS 60 (determining the current location; step 10). The identification unit 200 outputs the current location of the karaoke machine K determined in step 10 to the setting unit 300.

[0042] The setting unit 300 checks whether the current location of the karaoke machine K, identified in step 10, matches the venue included in the event information. The setting unit 300 also checks whether the date on which the current location was identified in step 10 matches the event date included in the event information.

[0043] If the current location of the identified karaoke machine K matches the venue included in the event information (if Y in step 11), and the date on which the current location was identified matches the date of the event included in the event information (if Y in step 12), the setting unit 300 will remain in a waiting state until a song is selected. The setting unit 300 may perform the processing in step 11 and step 12 first, or they may be performed simultaneously.

[0044] Suppose a song is then selected in the karaoke machine K (song selection; step 13). In this case, the setting unit 300 determines whether the time the song was selected falls between the start time and the end time included in the event information. If the time the song was selected falls within the start time and end time (case Y in step 14), the setting unit 300 determines whether the background video data of the selected song satisfies predetermined conditions.

[0045] If the background video data of the selected song is determined to meet predetermined conditions (Y in step 15), the setting unit 300 sets a special mode (sets special mode; step 16). On the other hand, if the background video data of the selected song is determined not to meet predetermined conditions (N in step 15), the setting unit 300 maintains the normal mode (maintains normal mode; step 17).

[0046] Specifically, suppose the organizer of event E requests karaoke operator KB to lend them a karaoke machine. Karaoke operator KB selects karaoke machine K as the machine to lend. Karaoke operator KB operates the remote control device 50 to input the date D of event E (December 24, 2024), the start time ST (13:00), the end time ET (19:00), and the location V (5-5-** Kitashinagawa, Shinagawa-ku, Tokyo) in advance. The remote control device 50 transmits each of the input pieces of information to the karaoke machine 10 as event information EI. The information storage unit 100 stores the event information EI received from the remote control device 50.

[0047] Subsequently, karaoke operator KB transports karaoke machine K to the venue (5-5-** Kitashinagawa, Shinagawa-ku, Tokyo) on the day of event E (December 24, 2024; date d). Karaoke operator KB then turns on the power to karaoke machine K.

[0048] When the karaoke machine K is powered on, the identification unit 200 identifies the current location P of the karaoke machine K (5-5-** Kitashinagawa, Shinagawa-ku, Tokyo) based on the location information acquired by the GPS 60. The identification unit 200 outputs the current location P to the setting unit 300. In this example, the current location P is identified by an address.

[0049] When the current location P is input from the identification unit 200, the setting unit 300 refers to the venue V included in the event information EI stored in the information storage unit 100. The setting unit 300 checks whether the current location P and the venue V match.

[0050] In this example, the current location P is identified as the venue for event E. Therefore, the current location P and the event venue V are the same.

[0051] On the other hand, for example, on the day of event E, let's say that karaoke operator KB turned on the power to the karaoke machine K at its warehouse (address: 3-11-** Mita, Minato-ku, Tokyo) in order to check its operation before transporting it to the venue.

[0052] When the karaoke machine K is powered on, the identification unit 200 identifies the current location P' (3-11-** Mita, Minato-ku, Tokyo) of the karaoke machine K based on the location information acquired by the GPS 60. The identification unit 200 outputs the current location P' to the setting unit 300.

[0053] When the current location P' is input from the identification unit 200, the setting unit 300 refers to the event location V included in the event information EI stored in the information storage unit 100. The setting unit 300 checks whether the current location P' and the event location V match.

[0054] In this example, the current location P' is identified as the warehouse of karaoke operator KB. Therefore, the current location P' does not match the event venue V. In this case, the setting unit 300 does not execute any further processing.

[0055] Furthermore, if the current location P of the karaoke machine K is input from the identification unit 200, the setting unit 300 refers to the event date D included in the event information EI stored in the information storage unit 100. The setting unit 300 checks whether the date d on which the current location P was identified matches the event date D.

[0056] In this example, the date d on which the current location P was identified is the day of event E. Therefore, the date d on which the current location P was identified and the event date D coincide.

[0057] On the other hand, for example, suppose that on the day before event E (December 23, 2024; date d'), karaoke operator KB transported karaoke machine K to the venue and turned on the power to karaoke machine K in order to check its operation.

[0058] When the karaoke machine K is powered on, the identification unit 200 determines the current location P of the karaoke machine K based on the location information acquired by the GPS 60. The identification unit 200 outputs the current location P to the setting unit 300.

[0059] When the current location P of the karaoke machine K is input from the identification unit 200, the setting unit 300 refers to the event date D included in the event information EI stored in the information storage unit 100. The setting unit 300 checks whether the date d' on which the current location P was identified matches the event date D.

[0060] In this example, the date d' on which the current location P was identified is the day before event E took place. Therefore, the date d' on which the current location P was identified does not match the event date D. In this case, the setting unit 300 does not execute any further processing.

[0061] If the current location P matches the venue V, and the date d on which the current location P was identified matches the event date D, the setting unit 300 will remain in a waiting state until a song is selected.

[0062] The organizer of Event E operates the remote control device 50 to select the song that the participant wishes to sing karaoke.

[0063] For example, when song X1 is selected, the setting unit 300 refers to the start time ST and end time ET included in the event information EI stored in the information storage unit 100. The setting unit 300 determines whether the time t1 when song X1 was selected falls within the period from the start time ST to the end time ET.

[0064] Let's assume that the time t1 at which song X1 was selected was "15:00". In this case, the time t1 at which song X1 was selected is included between the start time ST and the end time ET.

[0065] Therefore, the setting unit 300 determines whether the background video data ID***SV1 of the selected song X1 satisfies predetermined conditions.

[0066] Here, the background video data ID***SV1 of song X1 is associated with a video flag "1" that indicates a specific video. In this case, the setting unit 300 determines that the background video data ID***SV1 satisfies predetermined conditions and sets a special mode.

[0067] Subsequently, the karaoke device K begins playing the selected song X1. In this example, a special mode is set, so the karaoke device K displays a general-purpose video corresponding to pre-stored general-purpose video data on the display device 30, instead of the background video (i.e., specific video) corresponding to the background video data ID***SV1 of the selected song X1.

[0068] Alternatively, if song X3 is selected, the setting unit 300 refers to the start time ST and end time ET included in the event information EI stored in the information storage unit 100. The setting unit 300 determines whether the time t2 at which song X3 was selected falls within the period between the start time ST and the end time ET.

[0069] Let's assume that the time t2 at which song X3 was selected was "16:00". In this case, the time t2 at which song X3 was selected is included in the period from the start time ST to the end time ET.

[0070] Therefore, the setting unit 300 determines whether the background video data ID***GV1 of the selected song X3 satisfies predetermined conditions.

[0071] In this case, the background video data ID***GV1 for song X3 is associated with a video flag "0" which indicates a general-purpose video. In this case, the setting unit 300 determines that the background video data ID***GV1 does not meet the predetermined conditions and maintains normal mode.

[0072] Subsequently, the karaoke device K begins playing the selected song X3. In this example, the normal mode is maintained, so the karaoke device K displays the background video (i.e., a general-purpose video) corresponding to the background video data ID***GV1 of the selected song X3 on the display device 30.

[0073] On the other hand, suppose the time t3 at which song X1 was selected was "12:30". In this case, the time t3 at which song X1 was selected is not included in the period from the start time ST to the end time ET. In this case, the setting unit 300 does not execute any further processing.

[0074] As is clear from the above, the karaoke device K according to this embodiment is equipped with a GPS 60. The karaoke device K includes an information storage unit 100 that stores event information including the date, start time, end time, and location of an event; a location identification unit 200 that identifies the current location of the karaoke device K based on location information acquired by the GPS 60; and a setting unit 300 that, when the identified current location of the karaoke device K matches the location included in the event information of a certain event, when the date on which the current location was identified matches the date included in the event information of the certain event, when a song is selected in the karaoke device K between the start time and end time included in the event information of the certain event, and when the background video data of the selected song satisfies predetermined conditions, sets a special mode that changes the display manner of the background video, instead of the normal mode which displays the background video corresponding to the background video data of the song as is.

[0075] According to this karaoke device K, it is possible to automatically switch between normal mode and special mode based on the current location and event information. Therefore, for example, before renting out the karaoke device to an outdoor event, the karaoke operator does not have to go through the trouble of setting up the display of a specific video. In other words, according to the karaoke device K of this embodiment, the trouble of setting the display of the background video can be eliminated.

[0076] Furthermore, the setting unit 300 of the karaoke device K according to this embodiment can be set as a special mode to display a background image different from the background image corresponding to the background image data of the selected song. With such a karaoke device K, even when the special mode is set, the background image can be displayed on the display device 30 or the like in conjunction with the karaoke performance.

[0077] Furthermore, the setting unit 300 of the karaoke device K according to this embodiment can be set as a special mode in which the background video is not displayed. With such a karaoke device K, there is no need to prepare background video data in advance when setting the special mode, making it convenient.

[0078] <Variation> As described in the above embodiment, most general karaoke machines are set to normal mode by default. Therefore, if the current location of the identified karaoke machine matches the event venue, the date on which the current location was identified matches the event date, song selection takes place between the start and end times of the event, and the background video data of the selected song satisfies predetermined conditions, it is preferable that even if a special mode is initially set, the setting reverts to normal mode when the special mode is no longer needed.

[0079] Therefore, in this modified example, if the setting unit 300 cannot determine the current location of the karaoke device K after setting the special mode, and the end time included in the event information of a certain event has elapsed, it can set the normal mode instead of the special mode.

[0080] The current location of the karaoke machine K cannot be determined in cases such as when the karaoke machine is moved into a storage room within a warehouse, or when the location information of the karaoke machine cannot be obtained by GPS60.

[0081] For example, in the embodiment, let's assume that event E ends with a special mode set in the karaoke machine K. Also, let's assume that the karaoke operator KB takes back the karaoke machine K and returns it to storage in the warehouse.

[0082] Here, the karaoke operator KB operates the remote control device 50 and selects the "reset button" displayed on the display screen of the remote control device 50. In this case, the identification unit 200 attempts to determine the current location of the karaoke machine K based on the location information acquired by the GPS 60. On the other hand, suppose that location information could not be acquired by the GPS 60 in the storage room within the warehouse. If location information from the GPS 60 cannot be obtained for a certain period of time, the identification unit 200 outputs an error signal to the setting unit 300 indicating that the current location cannot be determined.

[0083] Upon receiving an error signal, the setting unit 300 compares the end time ET included in the event information EI of event E with the current time. If the end time ET has elapsed, the setting unit 300 switches from special mode to normal mode.

[0084] As described in the example of song X3 in the embodiment, there may be cases where a special mode is not set in the karaoke device K. In other words, there may be cases where an event ends without a special mode being set in the karaoke device K. In such cases, if a special mode is not set in the karaoke device K, the setting unit 300 does not perform any special processing, even if the current location of the karaoke device K cannot be determined and the end time included in the event information of a certain event has elapsed.

[0085] As is clear from the above, the setting unit 300 of the karaoke device K in this modified example can switch from the special mode to the normal mode if, after setting the special mode, the current location of the karaoke device K cannot be determined and the end time included in the event information of a certain event has elapsed. With such a karaoke device K, it is possible to return to the default normal mode without any extra effort.

[0086] Furthermore, if the setting unit 300 has set a special mode and the end time included in the event information of a certain event has elapsed, it may switch from the special mode to the normal mode. With such a karaoke device K, it is possible to return to the default normal mode without any extra effort.

[0087] <Other> It is also possible to supply the program to a computer using a non-transitory computer-readable medium (with an executable program thereon) on which the above program is stored. Examples of non-transitory computer-readable media include magnetic recording media (e.g., flexible disks, magnetic tapes, hard disk drives), CD-ROMs (Read Only Memory), etc.

[0088] The above embodiments are presented as examples and do not limit the scope of the invention. The above configurations can be combined as appropriate, and various omissions, substitutions, and modifications can be made without departing from the spirit of the invention. The above embodiments and their variations are included in the scope and spirit of the invention, as well as in the claims of the invention and its equivalents. [Explanation of symbols]
