  The present invention relates to a karaoke apparatus that provides a reproduction service for karaoke performance songs.

  Conventionally, a technique for providing a reproduction service for a karaoke performance has been proposed (see, for example, Patent Document 1).

  In this prior art, the memory of the karaoke device (automatic performance device) is instructed to generate pitch data and time data for automatically playing a desired music piece, and the voice of an assistant person such as a voice of a desired pitch or a hand of match. The sound generation command signal to be stored is stored as the performance progresses. The waveform memory circuit stores human voice data corresponding to the auxiliary human voice. Then, pitch data is read from the memory based on the time data, and a musical tone is generated from the sound system, so that automatic performance, that is, reproduction of karaoke performance music is performed. On the other hand, human voice data is read from the waveform storage circuit based on the sound generation command signal and pitch data read from the memory, and an auxiliary human voice is generated from the sound system. Thus, a desired assistant voice can be automatically reproduced at an arbitrary timing during the reproduction of the karaoke performance music.

JP-A-8-339183

  In the above-described prior art, an auxiliary voice such as a crying voice with a desired pitch or a matching hand is generated during the reproduction of a karaoke performance piece, thereby only improving the interest of the user. In other words, no particular consideration was given to the user's feelings, physical condition, throat tone, proficiency with respect to the performance, or the user's personality.

  An object of the present invention is to provide an appropriate entertainment service that closely corresponds to the user's current feelings, physical condition, throat tone, proficiency level for the performance song, or the personality of the user. To provide an apparatus.

  In order to achieve the above object, the first invention is a karaoke apparatus that provides a karaoke performance reproduction service using music data and background video data, and accepts a reservation of the karaoke performance music by a user. Reading from the music data storage means based on the reservation received by the reservation receiving means, music data storage means for storing the music data, video data storage means for storing the background video data, and the reservation receiving means And a display unit capable of displaying the background video data read from the video data storage unit as the music data is played back by the music playback unit. Voice signal input means for inputting a voice signal of karaoke singing by the user, and the music reproducing means When the recorded music data is reproduced, the karaoke singing voice signal input from the voice signal input means is scored every time a predetermined time period ends, The scoring result storage means for sequentially storing the scoring results by the scoring means, and each time when the predetermined time section is finished, it is replaced with the background video data displayed on the display means at that time. Display control means for controlling the display means so as to display interrupt video data according to the scoring result by the scoring means corresponding to the time section, and each time section that has been completed, A new scoring result by the scoring means, and a scoring result stored in the scoring result storage means for the time segment immediately before the completed time segment, Comparing means for compare, according to the comparison result of the comparing means, characterized by having a a sorting control means for variably controlling the length of the subsequent of said time segment.

  In the karaoke apparatus according to the first aspect of the present invention, when the user reserves a karaoke performance song, the song data corresponding to the karaoke performance song is read from the song data storage means and reproduced by the song reproduction means, and the background image Data is read by the video data storage means and displayed by the display means. The background video data may be data associated with a reserved performance piece, or may be data unrelated to the reservation. When the user sings the karaoke performance song in accordance with the reproduction of the music data, an audio signal of the karaoke song is input by the audio signal input means. The input voice signal is scored according to a predetermined scoring standard for each predetermined time segment.

  Here, in the first invention of the present application, in order to enhance entertainment, an interrupt display corresponding to the scoring result for each time segment is performed under the control of the display control means. That is, the display means stops displaying the background video data every time the time segment ends, and displays interrupt video data corresponding to the scoring result of the completed time segment instead. Thereby, since the user can recognize how the immediately preceding self song was evaluated with a visually strong impression, the interest of the user can be improved.

  Further, in the first invention of the present application, the comparing means further includes a new scoring result obtained when a certain time section ends, and a scoring result of the previous time section stored in the scoring result storage means. Compare Then, the division control unit variably controls the length of the subsequent time divisions according to the comparison result of the comparison unit. As a result, if the scoring result has improved from the previous time, it is considered that the user's singing motivation has improved due to the interrupt display and the singing tone has improved, and further time is taken to enhance the user's singing motivation. The section can be shortened, and the next interrupt video data can be displayed earlier at a shorter interval than before. Conversely, if the scoring result is lower than the previous time, the user's willingness to sing is disturbed by the interrupt display, and the user's singing condition is considered to be worse, and the decline in the user's singing will be recovered Therefore, the time segment is lengthened, and the next interrupt video data can be displayed later at a longer interval than before.

  As described above, in the first invention of the present application, the display interval of the interrupt video data of the user is changed while the improvement of the user's interest by displaying the interrupt video data is fundamental. Accordingly, it is possible to provide an appropriate entertainment service that closely corresponds to the user's feelings, physical condition, throat tone, proficiency level for the performance music, or the user's personality.

  According to a second aspect of the present invention, in the first aspect of the invention, the division control unit determines that the new scoring result for the completed time segment is greater than the scoring result of the previous time segment in the comparison result by the comparison unit. In the case where the score is also low, an expansion control means for controlling to expand the length of the time section is included.

  In the second invention of this application, when the score is lower than the previous time segment, it is considered that the user's willingness to sing is disturbed by the interrupt display, and the tune of the singing is getting worse. Display data at a longer interval and later. Thereby, the fall of a user's singing motivation can be further compensated.

  According to a third aspect of the present invention, in the first or second aspect of the present invention, the division control unit is configured such that, in the comparison result by the comparison unit, the new scoring result with respect to the completed time division is a value of the previous time division. When the score is higher than the scoring result, a reduction control means for controlling to reduce the length of the time segment is included.

  In the third invention of the present application, when the score is improved over the previous time segment, it is considered that the user's willingness to sing is improved by the interrupt display and the tune of the singing has improved, the time segment is shortened, and the next interrupt video The data is displayed earlier at shorter intervals than before. Thereby, a user's willingness to sing can be raised further.

  According to a fourth invention, in the third invention, an initial time segment storage unit that stores an initial value of the time segment, and a new time segment in which the length of the time segment is reduced by the reduction control unit, A determination unit that determines whether or not the initial value stored in the initial time segment storage unit is less than the initial value, and when the determination unit determines that the new time segment is less than the initial value, There is provided reduction reduction means that does not reduce the length of the time segment and sets the length of the time segment at that time as the length of the new time segment.

  As a result, even if the scoring results continue to improve, the minimum value of the time segment shortened by the reduction control means is set as the initial time segment in the karaoke performance piece so as not to be shortened below the time segment. can do. In addition, by not making it smaller than the original time division of the karaoke performance song, even if the scoring results continue to improve immediately after the start of singing, the interrupt video data is interrupted at intervals that are excessively close to the background video data, and the background image is It is possible to prevent the singing of the karaoke from being difficult while watching.

  According to the present invention, it is possible to provide an appropriate entertainment service that closely corresponds to the user's current feelings, physical condition, throat tone, proficiency level for the performance music, or the user's personality.

  Thereafter, when the ninth section (30 seconds) corresponding to the length of the time section at this time (30 [seconds / section]) is finished, the voice of the karaoke song input by the microphone 105 in the finished ninth section. The signal is scored. In this example, the voice signal of the karaoke song is scored as 80 points. That is, the new scoring result (80 points) for the ninth division is higher than the scoring result (70 points) of the previous eighth division.

  In this case, the display screen of the display unit 109 moves to the screen D10. On the screen D10, the interrupt video image CP3 related to the above-described score-up effect is interrupted and displayed instead of the background video GP displayed on the display unit 109 at that time, and the scoring result in the ninth section is displayed. A corresponding telop S (“80 points”) is displayed.

  At this time, similarly to the above, if the shortened value (5 seconds) is subtracted from the current time segment length (30 seconds), the new time segment becomes 25 [seconds / segment] It becomes less than the initial value of the time division (30 [seconds / division]). In the present embodiment, when the new time segment becomes less than the initial value of the time segment in this way, the length of the time segment is not reduced, and the length of the time segment at that time (30 seconds) ) Is the length of the new time segment.

  Thereafter, when the tenth section (30 seconds) corresponding to the length of the time section at this time (30 [seconds / section]) is completed, the voice of the karaoke song input by the microphone 105 in the finished tenth section The signal is scored. In this example, the voice signal of the karaoke song is scored as 90 points. That is, the new scoring result (90 points) for the 10th division is higher than the scoring result (80 points) of the previous 8th division.

  In this case, the display screen of the display unit 109 moves to the screen D11. On the screen D11, the interrupt video image CP3 related to the above-described score-up effect is interrupted and displayed instead of the background video GP displayed on the display unit 109 at that time, and the scoring result in the tenth section is displayed. Corresponding telop S (“90 points”) is displayed.

  At this time, similarly to the above, if only the shortened value (5 seconds) is subtracted from the current time segment length (30 seconds), the new time segment becomes 25 [seconds / segment]. Since the time segment is less than the initial value (30 [seconds / segment]), the length of the time segment is not reduced, and the current time segment length (30 seconds) is the length of the new time segment. It is assumed.

  After that, as the reproduction of the MIDI data corresponding to the karaoke performance song is finished, the display of the background image data and the like on the display unit 109 is also finished.

  A control procedure executed by the control unit 101 of the karaoke apparatus 100 will be described with reference to FIG.

  In FIG. 7, for example, when the karaoke apparatus 100 is turned on by a system administrator (not shown), this flow is started as represented by a “START” position in the drawing.

  First, in step S10, the control unit 101 determines whether reservation for karaoke performance music has been received based on a reservation operation for karaoke performance music performed by the user via the operation unit 104 or the operation unit 204 of the remote controller 200. Until the user accepts a reservation for a karaoke performance song, the determination is not satisfied and the system waits in a loop. And if the reservation of the karaoke performance music by a user is received, determination will be satisfy | filled and it will move to step S20. In addition, this step S10 functions as a reservation receiving means described in each claim.

  In step S20, based on the reservation of the karaoke performance song received in step S10, the control unit 101 stores the MIDI data, background video data, and lyrics data corresponding to the karaoke performance song related to the reservation from the large-capacity storage device 103. Etc. are read out. Then, a control signal is output to the sound source 106 and the like to start reproduction of the read-out MIDI data, and a control signal is output to the display unit 109 to synchronize with reproduction of the MIDI data by the sound source 106 and the like. Display of the read background video data and lyrics data is started.

  Thereafter, in step S <b> 30, the control unit 101 reads an initial value T <b> 0 (for example, T <b> 0 = 30 [second / division]) of the time division from the mass storage device 103. The length T of the time section is set as the read initial value T0.

  Then, the process proceeds to step S40, where the control unit 101 resets a timer time t, which is a timer (not shown), to 0, and starts a timer.

  Thereafter, in step S50, the control unit 101 determines whether or not the time measured by the timer started in step S40 is equal to the time segment length T at this time, in other words, one time segment is completed. Determine if you did. If t = T is not satisfied, in other words, if one time segment has not yet ended, the determination is not satisfied and the routine goes to Step S60.

  In step S60, the control unit 101 determines whether or not the reproduction of the MIDI data by the sound source 106 or the like started in step S20 has been completed. If the reproduction of the MIDI data or the like has not been completed yet, the determination is not satisfied and the routine returns to step S50 and the same procedure is repeated. On the other hand, if the reproduction of the MIDI data or the like has been completed, the determination is satisfied and this flow is terminated.

  On the other hand, if t = T in step S50, in other words, if one time segment is completed, the determination in step S50 is satisfied, and the process proceeds to step S70.

  In step S70, after the MIDI data is reproduced by the sound source 106 or the like in step S20, the control unit 101 starts from the time measurement by the timer in step S40 until the determination in step S50 is satisfied. The voice signal of the user's karaoke singing input from the microphone 105 is scored according to a predetermined scoring standard. In other words, this corresponds to scoring the voice signal of the user's karaoke singing input from the microphone 105 in the time period ended. Note that this scoring need only be performed by a known appropriate method, and thus detailed description thereof is omitted. Further, this step is executed every time the time segment ends, as shown in the flow. Therefore, this step functions as scoring means described in each claim.

  Then, the process proceeds to step S80, and the control unit 101 determines the new scoring result for the completed time segment in step S70 and the completed time segment stored in the mass storage device 103 in step S170 described later. Compare the scoring result of the previous time segment. Then, it is determined whether or not the new scoring result has the same score as the scoring result of the previous time segment. If the new scoring result has the same score as the scoring result of the previous time segment, and if the past scoring result is not stored in the mass storage device 103, the determination is satisfied and the step The process moves to S90. This step S80 is also executed every time the time segment ends, as shown in the flow.

  In step S90, the control unit 101 displays interrupt video data related to the score invariant effect on the display unit 109 at this time as interrupt video data corresponding to the scoring result in step S70 corresponding to the completed time segment. Instead of the displayed background video data, the display unit 109 is controlled so as to interrupt and display only for a predetermined time (for example, 5 seconds). At this time, the control unit 101 also causes the display unit 109 to display the scoring result in step S70 corresponding to the completed time segment. Thereafter, the process proceeds to step S170 described later. This step S90 is also executed every time the time segment ends, as shown in the flow.

  On the other hand, if the new scoring result is not the same as the scoring result of the previous time segment in step S80, the determination in step S80 is not satisfied and the process proceeds to step S100.

  In step S100, the control unit 101 determines the new scoring result for the completed time segment in step S70 and the previous time segment stored in the mass storage device 103 in step S170 described later. Compare the scoring results of the time divisions. Then, it is determined whether or not the new scoring result is higher than the scoring result of the previous time segment. If the new scoring result is lower than the scoring result of the previous time segment, the determination is not satisfied and the routine goes to Step S110. Note that this step S100 is also executed every time the time segment ends, as shown in the flow.

  In step S110, the control unit 101 displays interrupt video data related to the score down effect on the display unit 109 at this time as interrupt video data corresponding to the scoring result in step S70 corresponding to the completed time segment. Instead of the displayed background video data, the display unit 109 is controlled so as to interrupt and display only for a predetermined time (for example, 5 seconds). At this time, the control unit 101 also causes the display unit 109 to display the scoring result in step S70 corresponding to the completed time segment. Note that this step S110 is also executed every time the time segment ends, as shown in the flow.

  Thereafter, in step S120, the control unit 101 adds the time segment extension value a (for example, a = 5 [seconds]) to the time segment length T at that time point to obtain a new time segment length. . That is, this substantially corresponds to controlling the time segment to be extended. Thereafter, the process proceeds to step S170 described later.

  On the other hand, when the new scoring result is higher than the scoring result of the previous time segment in step S100, the determination in step S100 is satisfied and the process proceeds to step S130.

  In step S130, the control unit 101 displays interrupt video data related to the score-up effect on the display unit 109 at this time as interrupt video data corresponding to the scoring result in step S70 corresponding to the completed time segment. Instead of the displayed background video data, the display unit 109 is controlled so as to interrupt and display only for a predetermined time (for example, 5 seconds). At this time, the control unit 101 also causes the display unit 109 to display the scoring result in step S70 corresponding to the completed time segment. Note that this step S130 is also executed every time the time segment ends, as shown in the flow.

  Then, the process proceeds to step S140, where the control unit 101 determines that the value Tb obtained by subtracting the time segment shortened value b (for example, b = 5 [seconds]) from the time segment length T at that time is the above-described large value. It is determined whether or not the time section stored in the capacity storage device 103 is less than the initial value T0. This substantially corresponds to determining whether or not a new time segment in which the length T of the time segment is reduced in step S150 described later is less than the initial value T0. This step functions as determination means described in each claim. If Tb <T0, that is, if a new time segment in which the time segment length T is reduced in step S150 described later is less than the initial value T0, the determination is satisfied and the process returns to step S150. Move.

  In step S150, the control unit 101 subtracts the time segment extension value b from the current time segment length T to obtain a new time segment length. This substantially corresponds to controlling to reduce the length of the time section. Thereafter, the process proceeds to step S170 described later.

  On the other hand, if T−b ≧ T0 in step S140, that is, if a new time segment in which the length T of the time segment is reduced in step S150 is greater than or equal to the initial value T0, step S140. This determination is not satisfied, and the routine goes to Step S160.

  In step S <b> 160, the control unit 101 reads the initial value T <b> 0 of the time segment from the mass storage device 103. The length T of the time section is set as the read initial value T0. This substantially corresponds to the fact that the time segment length T is not reduced, and the time segment length T at that time, in other words, the initial value T0 is set as a new time segment.

  In step S <b> 170, the control unit 101 stores the scoring result in step S <b> 70 corresponding to the completed time segment in the large-capacity storage device 103. Since this step is executed every time the time segment ends, the control unit 101 causes the mass storage device 103 to sequentially store the scoring results in step S70 for each time segment. Then, it returns to said step S40 and repeats the same procedure.

  In the above, step S90, step S110, and step S130 function as display control means described in each claim. Steps S80 and S100 function as comparison means.

  Furthermore, step S120, step S150, and step S160 function as a division control unit that variably controls the length of subsequent time divisions according to the comparison result of the comparison unit. Of these, step S120 functions as an enlargement control unit, and step S150 functions as a reduction control unit. Step S160 also functions as a reduction canceling unit.

  As described above, in this embodiment, when a user reserves a karaoke performance song, MIDI data corresponding to the karaoke performance song is read from the large-capacity storage means 103 and reproduced by the sound source 106 or the like. . At the same time, background video data and the like are read from the large-capacity storage means 103 and displayed on the display unit 109. When the user sings the karaoke performance song in accordance with the reproduction of the MIDI data, an audio signal of the karaoke song is input by the microphone 105. The input voice signal is scored according to a predetermined scoring standard for each predetermined time segment.

  Here, in the present embodiment, in order to enhance entertainment, an interrupt display corresponding to the scoring result for each time segment is performed under the control of the control unit 101 of the karaoke apparatus 100. That is, the display unit 109 stops displaying the background video data every time the time segment ends, and instead displays the interrupt video data according to the scoring result of the completed time segment. Thereby, since the user can recognize how the immediately preceding self song was evaluated with a visually strong impression, the interest of the user can be improved.

  Further, in the present embodiment, the control unit 101 further determines that the new scoring result obtained when a certain time segment ends and the scoring result of the previous time segment stored in the mass storage device 103. And compare. Then, the control unit 101 variably controls the length T of the subsequent time sections according to the comparison result. As a result, if the scoring result has improved from the previous time, it is considered that the user's singing motivation has improved due to the interrupt display and the singing tone has improved, and further time is taken to enhance the user's singing motivation. The section can be shortened and the next interrupt video data can be displayed earlier at a shorter interval than before. Conversely, if the scoring result is lower than the previous time, the user's willingness to sing is disturbed by the interrupt display, and the user's singing condition is considered to be worse, and the decline in the user's singing will be recovered Therefore, the time segment can be lengthened and the next interrupt video data can be displayed later at a longer interval than before.

  As described above, in this embodiment, the display interval of the interrupt video data of the user is changed while the improvement of the user's interest by displaying the interrupt video data is fundamental. Accordingly, it is possible to provide an appropriate entertainment service that closely corresponds to the user's feelings, physical condition, throat tone, proficiency level for the performance music, or the user's personality.

  In the present embodiment, in particular, the control unit 101 of the karaoke apparatus 100 determines that the new scoring result for the completed time segment is higher than the scoring result of the previous time segment in the comparison result in step S100. If the score is low, control is performed to increase the length T of the time segment (see step S120). In other words, if the score is lower than the previous time segment, it is assumed that the user's willingness to sing is hampered by the interrupt display, and the singing condition has deteriorated. Is displayed at longer intervals than before. Thereby, the fall of a user's singing motivation can be further compensated.

  In the present embodiment, in particular, the control unit 101 of the karaoke apparatus 100 determines that the new scoring result for the completed time segment is higher than the scoring result of the previous time segment in the comparison result in step S100. If the score is high, control is performed to reduce the length T of the time segment (see step S150). In other words, if the score improves compared to the previous time segment, it is considered that the user's willingness to sing improved by the interrupt display and the tune of the song has improved, the length of the time segment is shortened, and the next interrupt video data Is displayed earlier at shorter intervals than before. Thereby, a user's willingness to sing can be raised further.

  In the present embodiment, in particular, the control unit 101 of the karaoke apparatus 100 determines that the new time segment in which the length T of the time segment is reduced is less than the initial value T0 of the time segment stored in the mass storage device 103. Is determined (see step S140). If it is determined that the new time segment is less than the initial value T0, the control unit 101 does not reduce the length T of the time segment, and does not reduce the time segment length T. Is the length of the new time segment (see step S160). As a result, even when the scoring results continue to improve, the minimum value of the time segment shortened by the control unit 101 is set as the initial time segment in the karaoke performance piece so as not to be shortened below the time segment. can do. In addition, by not making it smaller than the original time division of the karaoke performance song, even if the scoring results continue to improve immediately after the start of singing, the interrupt video data is interrupted at intervals that are excessively close to the background video data, and the background image is It is possible to prevent the singing of the karaoke from being difficult while watching.

  In the present embodiment, in particular, the control unit 101 of the karaoke apparatus 100 subtracts the time segment length T at that time by a predetermined fixed value b to obtain a new time segment length. To do. As a result, the length of the time segment can be sequentially reduced step by step by a predetermined fixed value b.

  The present invention is not limited to the above-described embodiment, and various modifications can be made without departing from the spirit and technical idea of the present invention. Hereinafter, such modifications will be described.

(1) In the case of providing a mode that does not display interrupt video data In other words, a mode in which both background video data and interrupt video data can be switched and displayed, and background video data display without interrupt video data display You may make it provide the mode which performs.

  In the present modification, two modes, “normal mode” and “simple mode”, are provided as modes that can be selected by the user. The “normal mode” is a mode in which both the background video data and the interrupt video data can be switched and displayed. The “simple mode” is a mode in which the background video data is displayed without displaying the interrupt video data.

  The control procedure executed by the control unit 101 of the karaoke apparatus 100 in this modification will be described with reference to FIG.

  In FIG. 8, for example, when the system administrator turns on the power of the karaoke apparatus 100, this flow is started as represented by a “START” position in the figure.

  First, in step S <b> 210, the control unit 101 determines whether a mode selection has been accepted based on a mode selection operation by the user via the operation unit 104 or the operation unit 204 of the remote controller 200. Until the mode selection by the user is accepted, the determination is not satisfied and the process waits in a loop. And if the mode selection by a user is received, determination will be satisfy | filled and it will move to step S220.

  Thereafter, in step S220, the control unit 101 determines whether or not the mode received in step S210 is the “normal mode”. If it is “normal mode”, the determination is satisfied and the routine goes to Step S230.

  In step S230, the control unit 101 executes predetermined normal mode processing. The detailed procedure of the normal mode process is the same as that in FIG. Then, this flow ends.

  On the other hand, if the mode accepted in step S210 is “simple mode”, the determination in step S220 is not satisfied, and the process proceeds to step S400.

  In step S400, the control unit 101 executes a predetermined simple mode process. The detailed procedure of this simple mode process will be described later with reference to FIG. Then, this flow ends.

  The detailed procedure of step S400 in FIG. 8 will be described with reference to FIG. FIG. 9 corresponds to FIG. 7 described above. The same steps as those in FIG. 7 are denoted by the same reference numerals and description thereof will be omitted as appropriate.

  9 differs from FIG. 7 described above in that step S80 to step S170 are omitted and step S410 is newly provided. That is, in step S70, when the control unit 101 scores the voice signal of the user's karaoke song input from the microphone 105 in the completed time segment, the process proceeds to the newly provided step S410.

  In step S410, the control unit 101 displays so as to display the scoring result in the above-described step S70 corresponding to the ended time segment together with the background video data currently displayed on the display unit 109. The unit 109 is controlled. This substantially corresponds to controlling the display unit 109 so that the background video data is displayed without displaying the interrupt video data every time a predetermined time interval ends. This step also functions as display control means described in each claim.

  According to this modification, the same effects as those of the above embodiment are obtained. Furthermore, in the present modification, the control unit 101 of the karaoke apparatus 100 includes the “normal mode” and the “simple mode” described above. If the mode accepted in step S210 in FIG. 8 is “simple mode”, the control unit 101 does not display interrupt video data every time a predetermined time segment ends, and displays the background video. The display unit 109 is controlled to display data. As a result, it is necessary to display the interrupt video data based on the scoring results due to circumstances such as the user's current feeling, physical condition, throat tone, proficiency level for the performance song, or the user's personality, etc. If intended, interrupt video data will not be displayed by selecting “Simple mode”. As a result, the user can enjoy singing with a calm display without interruption by interrupted video data.

  Further, the flowcharts shown in FIGS. 7, 8, and 9 do not limit the present invention to the procedures shown in the above-described flow, and the addition / deletion of the procedures or the order of the procedures are within the scope not departing from the spirit and technical idea of the invention. Changes may be made.

  In addition to those already described above, the methods according to the above-described embodiments and modifications may be used in appropriate combination.

  In addition, although not illustrated one by one, the present invention is implemented with various modifications within a range not departing from the gist thereof.
