DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for displaying a background image on a monitor in a karaoke machine in time with music to be played, and an apparatus for implementing the method for displaying the background image. The present invention relates to a method and an apparatus for displaying a background image of a karaoke machine in which a background image to be displayed on a monitor is appropriately selected in accordance with a tune arbitrarily selected.

[0002]

In recent years, karaoke machines capable of displaying a background image of a song selected by a singer on a monitor in accordance with the song have been widely used.

[0003] Such a karaoke machine is provided with a high recreational ability to inflate the feast by inflating the image of the song by the background image projected on the monitor.
Although it has spread rapidly, the original method of preparing background video corresponding to each song stores the same number of background videos on the recording medium as the number of karaoke songs prepared in the karaoke machine It is necessary, and with the increase in the number of karaoke songs, a shortage of recording capacity in the recording medium of the karaoke machine has become a problem.

Therefore, a karaoke machine has been developed in which not only a karaoke song but also a background image can be selected, and a singer can sing by arbitrarily combining the song and the background image. Such a method of displaying a background image is widely used especially in a so-called communication karaoke machine, which has a very wide selection range of music and is attracting attention as a next-generation karaoke machine.

Here, in a karaoke machine which can arbitrarily combine such a music and a background image, the performance time usually differs for each music.
When combining arbitrarily selected music and the background video, a new problem arises in that the music performance time and the background video time do not match. Prepare the video as a background video that can be selected arbitrarily, and if the performance time of the music is shorter than the video time of the background video or if the performance time is longer than the video time and the background video is displayed repeatedly, the music Even if the background video is interrupted midway after the performance of the singer, the singer is not made to feel strange.

However, in a conventional karaoke machine capable of arbitrarily combining such a music piece with a background image, as described above, the performance time of the music piece differs for each music piece, so that the karaoke machine is prepared. The background image is limited to the image without the story, and the original purpose of displaying the background image according to the image of the music being played, such as raising the atmosphere of the party, is not enough. There is a problem that is not achieved.

[0007] Karaoke machines include a karaoke machine with a scoring function for scoring the singing ability of a singer and displaying the scoring on a background video monitor.
No. 205, a video corresponding to the singing ability of the singer is displayed on the monitor for each predetermined band of the performance time of the music during the performance of the music, and the video replaces the score. Karaoke machines that evaluate the singing ability of singers have also been developed. However, in the case of a karaoke machine with a scoring function, if the display method that allows the combination of the music and the background video as described above is adopted arbitrarily, the performance time of the music is similarly reduced This causes a problem that the background image prepared in the karaoke machine is limited to an image having no story.

The present invention has been made to solve the above-mentioned problems of the conventional karaoke machine.

That is, the present invention provides a karaoke machine which can arbitrarily combine music and a background image.

The character image of the lyrics generated by the character data in the music data is overlaid on the background video signal, output to the output unit E, and displayed on the monitor.

The RAM 17 of the changer B stores various data necessary for controlling error data and the like. Further, each control in the changer B as described above is controlled by the CPU 10.

Next, with reference to FIGS. 2 and 3, a description will be given of the principle of the background video reproduction control in the case where the performance time of the music to be performed is different from the video time of the background video. Here, FIG. 2 illustrates the principle of background video playback control when the scoring mode is off in the karaoke machine of FIG.
FIG. 3 shows the principle when the scoring mode is on,
In each case, these controls are controlled by controller A's C
It is performed in cooperation with the CPU of the changer B based on a command from the PU 1 (see FIG. 1).

First, the case where the scoring mode is off will be described with reference to FIG. When the background video corresponding to the music is selected, the CPU 1 refers to the management data in the HDD 6 and, as the selected background video data, the start portion S, the end portion F, and the start portion S and the end portion F of the video. The recording position on the DVD of each of the three band sections of the intermediate portion M is specified. (FIG. 2 (a)).

The starting portion S and intermediate portion M of the background video data
The video time of each band of the ending unit F and the video time of the background video prepared in the karaoke machine is allocated to a predetermined ratio according to the video time of the selected background video when the video time of the background video is different. And the starting part S
And the video time of the band of the end part F is set to be a fixed predetermined time, and the video time of the band of the middle part M is adjusted according to the video time of each background video. However, in this example, the background video of the same video time is prepared in the karaoke machine, and even if any background video is selected, the start portion S and the intermediate portion M
The video time of the end part F is set to be a fixed time.

That is, in this example, the entire video time of the background video for one song prepared in the karaoke machine is 4 minutes, the video time in the band of the start section S is 30 seconds, and the middle section M
Is set to be 3 minutes, and the video time of the band of the end section F is set to 30 seconds.

When the background video is displayed in synchronization with the performance time longer than the video time of the background video, for example, 5 minutes, as shown in FIG. For 30 seconds from the start of the performance, the video reproduced from the band of the start portion S of the background video data is displayed on the monitor, and for the next 3 minutes, the video reproduced from the band of the middle portion M is displayed on the monitor. For one minute, the image in the band of the middle part M is displayed in a repeated manner. When one minute elapses when the image in the band of the middle part M is repeated, the reproduction of the image from the background image data is performed in the band of the middle part M. From the end portion F of the background music data for the last 30 seconds of the music playing time.

In the above description, after the reproduction of the video from the band of the middle section M for 3 minutes is completed, the video is not repeated from the beginning of the band of the middle section M in the next minute, but is shown in FIG. (B), the start portion S
May be repeated from the beginning of the band.

If the performance time is shorter than the video time of the background video, for example, when the background video is displayed along with a three-minute tune, the music tune is displayed as shown in FIG. During a period of 30 seconds from the start of the performance, the video reproduced from the band of the start portion S of the background video data is displayed on the monitor 3 as in the case of FIG. The video reproduced from the background video data is displayed on the monitor.
From the band of the background video data, the video is reproduced from the band of the end portion F of the background video data for the last 30 seconds of the music performance time.

As described above, in this example, the first introduction part (starting part S) and the last complete part (ending part F) of the background video are always irrespective of the length of the playing time of the music to be performed. Are displayed on the monitor for a certain period of time, respectively, so that the story of the background image is not significantly impaired.

Next, a case where the scoring mode is ON will be described with reference to FIG. Here, the scoring mode includes a mode for scoring the singing ability of the singer and displaying the score on a monitor (hereinafter, this mode is simply referred to as a scoring mode),
There is a mode in which the evaluation of the singing ability is displayed by switching the content of the background video using the multi-angle of the DVD (hereinafter, this mode is referred to as a scoring video mode). Since it is the same as the case of FIG. 2 described above, the case of the scoring video mode will be described here.

Here, the multi-angle function of the DVD means that a plurality of videos proceeding simultaneously within the same time are recorded on a disc, and the plurality of videos proceeding simultaneously can be arbitrarily switched and displayed. This is a function that can be performed, and has a characteristic that a seamless video can be displayed seamlessly when the angle is switched.

First, regarding this scoring video mode, FIG.
If you want to explain a little more with reference to
Has recorded therein a multi-angle (in this example, 5 angles) background image that gradually images the evaluation of the singing ability. For example, the background image of the angle 1 has a bright image indicating a high evaluation of the singing ability. As the angle goes from the angle 1 to the angle 5, the image becomes a dark image showing a low evaluation of the singing ability.

When the background video is switched to an angle corresponding to the evaluation of the singing power at predetermined time intervals after the music performance starts, the evaluation of the singing power is displayed by the image of the background video. Is done.

In the example of FIG. 4, at the start of the performance, the background video of the angle 3 is displayed, and every 30 seconds (each x point in the figure), the background video corresponds to the evaluation of the singing ability during the elapsed 30 seconds. The angle can be switched to the one you want. The first angle switching is performed 30 seconds after the performance starts. Then, 30 seconds before the end of the performance (point y in the figure), the background video is switched to an angle corresponding to the comprehensive evaluation of the singing ability. The comprehensive evaluation is performed, for example, by averaging the evaluations performed so far.

In the above, the angle switched 30 seconds before the end of the performance corresponds to the comprehensive evaluation of the singing ability, because the karaoke machine displays the score of the final judgment of the singing ability after the end of the performance. If so,
This is to ensure that the score of the final judgment displayed matches the background video image displayed at the end of the performance. The evaluation of the singing ability in the middle of the song may always be the average value of the singing ability from the beginning of the song.
Further, the score of the final determination may be the last score.

In the above-described scoring video mode, as shown in FIG. 3A, each of the angles 1 to 5 of the selected background video data is set at the start of the video in the same manner as in FIG. S, an end part F, and an intermediate part M between the start part S and the end part F, which are divided into three bands. The video time of the band of the start part S is 30 seconds, the image time of the intermediate part M is 3 minutes, The video time of the band of the end section F is set so as to be 30 seconds.

As shown in FIG. 3 (a), the following description will be made for each angle band at the start part S and the end part F and for each angle band at the middle part M every 30 seconds. This is performed using the reference numerals assigned to the divided portions.

First, the performance time is set to the video time (4
If the background video is displayed in time with the music of 5 minutes, for example, as shown in FIG. 3B, the background video data is stored for 30 seconds from the start of the performance of the music. The video reproduced from the band of the start portion S is displayed on the monitor. At this time, no scoring result has been output for 30 seconds from the start of the performance of the music, so that the band of S3 of the angle 3 representing the medium evaluation is displayed. Is displayed.

Then, for the next three minutes, the video reproduced from the band of the middle part M is displayed on the monitor, and at this time, the angle of the background video is switched to the one corresponding to the evaluation of the singing ability every 30 seconds. For example, in the example of FIG. 3B, the angle in the band of the middle part M is M2-1 → M1.
Switching is performed in the order of -2 → M2-3 → M3-4 → M4-5 → M4-6, and the evaluation of the singing power every 30 seconds is displayed.

For the next one minute, the background image is displayed while being repeated from the band of the middle part M. In the example shown in the figure, similarly,
The angle is switched from M5-1 to M4-2 every 30 seconds.

When one minute elapses during the video repeat in the band of the middle section M, the display of the video jumps from the band of the middle section M to the band of the end section F, and the last of the music playing time is reached. For 30 seconds, an image in the band of the end section F is displayed. At this time, the angle of the background video displayed from the band of the end portion F corresponds to the score of the final determination of the singing ability, and F3 is displayed in the illustrated example.

In the above description, after the reproduction of the video from the band of the intermediate section M for 3 minutes is completed, the video is not repeated from the beginning of the band of the intermediate section M in the next minute, but is shown in FIG. Similarly to the case of the example, the video according to the evaluation at that time may be selected from the band of the start part S and repeated.

When the performance time is shorter than the video time of the background video, for example, when the background video is displayed in synchronization with a three-minute music, the performance of the music starts as shown in FIG. 3 to 30 seconds, the video of S3 in the band of the start portion S of the background video data is displayed on the monitor in the same manner as in the case of FIG. In response to the evaluation of the singing ability, for example, M3-1 → M2-2 →
The image of the angle switched as M2-3 → M1-4 is displayed on the monitor.

After the lapse of two minutes, the reproduction of the video from the background video data jumps from the band of the middle part M to the band of the end part F, and the last 30 minutes of the music performance time.
In the second, an angle corresponding to the score of the comprehensive judgment of the singing ability in the band of the end portion F, for example, a background image of F2 is displayed.

As described above, even in the scoring video mode, the first introduction part (starting part S) and the last complete part (ending part F) of the background video are always irrespective of the duration of the music to be performed. ) Are displayed on the monitor for a certain period of time, respectively, so that the storyliness of the background image is not significantly impaired.

In the above-described scoring video mode, by using the multi-angle function of the DVD to switch the background video, it is possible to display a so-called seamless video in which the video is not interrupted at the time of the switching. become.

Next, the display control of the background video in the karaoke machine will be described with reference to the flowcharts shown in FIGS. This control is performed by the CPU 1 (FIG. 1).
), And is performed in cooperation with the CPU 10.

In FIG. 5, the CPU 1 performs a request accepting process based on a song request by a singer or the like (step a), and after performing the request accepting process, performs a performance process of the requested song (step a). Step b).

The request receiving process is performed according to a procedure as shown in FIG. That is, the CPU 1 operates the operation unit 5
, And determines whether the input is a music request, that is, a music number input. (Step a
1) If the music number has been input, it is determined whether or not the data of the next requested music is stored in the HDD 6 or the CD-ROM of the disk stocker 12 (step a2). If music data is stored, the request music is registered (step a3).

In step a2, if the data of the requested music is not stored, a display indicating that there is no music data is performed (step a4). Step a1
If the input is not a song number, it is determined whether or not the input is for setting a scoring mode (a mode in which singing ability is scored and displayed) (step a5). Sets the scoring mode (step a6).

If it is determined in step a5 that the input is not for the setting of the scoring mode, it is determined whether or not the input is for setting the scoring video mode (mode for switching and displaying the background video according to the singing ability) (step a5). a7) If a scoring video mode setting is input, the scoring video mode is set (step a8).

If it is determined in step a7 that the input is not for setting the scoring video mode, it is determined whether or not the input is for setting the normal mode (a mode in which singing ability is not scored) (step a9). In the case of an input, the normal mode is set (step a10).

In step a9, if the input is not the normal mode setting, it is determined whether or not the input is for setting to another mode (for example, the shortened performance mode or the mode for displaying the ranking of the scoring) (step a9). In step a11), in the case of setting input of another mode, the input mode is set (step a12).

If it is determined in step a11 that the input is not an input for setting another mode, a message indicating an input error is displayed (step a13).

The performance processing performed after the end of the request reception processing as described above is performed according to the procedure shown in FIGS. 7, 8, and 9. That is, the CPU 1 determines whether or not the requested music is being played (step b).
1) If the music is being played, this determination is continued. If the music is not being played, the request music is registered (see FIG. 6).
Is determined (step b2).

In step b2, if the requested music is not registered, the performance process is terminated. If the music is registered, the requested music data is read out (step b3) and the timer value is set (step b4). ),
The background image is selected (step b5) and the timer is reset (step b6).

In the above, the setting of the timer value is as follows.
The standard performance time data included in the music data of the music to be played is detected and stored, and the performance is performed based on the data. A shortened performance mode, for example, a mode in which the second song is omitted is set. In this case, a time shorter than the standard performance time of the music is set as the performance time. In addition, the background video is selected from the videos for the normal mode and the scoring mode stored for each genre of the music, or the video for the scoring video mode, to select the video to be displayed as the background video according to the set mode. Is what you do. In this example, a plurality of numbers for setting the scoring video mode are defined, and the singer inputs one of the numbers so that the type of the background video displayed in the scoring video mode can be selected. ing.

After the end of step b6, the performance of the requested music is started (step b7), and at the same time, a timer is started (step b8).

As shown in FIGS. 8 and 9, when it is determined that the set display mode of the image is the normal mode (step b9), the normal mode is selected.
It is determined whether or not the reproduction of the background video has reached the end of the daytime section M (step b10). When the middle part M ends,
Specifically, a comparison is made between the video time of the selected background video and the timer value set in step b4, that is, the performance time of the music being played, and if the performance time is longer than the video time, From the video time of the video to the video time of the end portion F (see FIG. 2) of the background video data (3 in this example)
When the time obtained by subtracting (0 second) has elapsed, the image is jumped to the head of the middle part M (or the head of the start part S) of the background video data and displayed repeatedly (step b11). On the other hand, if NO in step b10, that is, if the middle part M is being reproduced, the process proceeds to step b12.

Further, the CPU 1 continuously monitors the elapsed time of the music performance (step b12), and the elapsed time from the start of the music performance is calculated based on the total performance time of the music and the video of the end portion F of the background video data. When the time is less than the time, jump from the middle part M of the background video data to the head of the end part F to reproduce the background video data of this end part F (step b13), otherwise, step b1
Return to 0.

The elapsed time from the start of the music performance is step b.
It is determined whether or not the timer value set in step 4 has elapsed, that is, whether or not the music performance time has elapsed (step b14). And the display of the background image ends (step b15).

If it is determined in step b9 that the set mode is not the normal mode, it is determined whether or not the scoring mode is set (step b16). After clearing the displayed previous scoring result (step b17), it is determined whether or not the reproduction of the background video has reached the end of the intermediate section M, as in the case of the normal mode described above (step b).
18). When the end of the middle part M is reached, the image is repeatedly displayed by jumping to the head of the middle part M (or the head of the start part S) of the background video data (step b1).
9). On the other hand, if the end of the intermediate section M has not been reached, the process proceeds to step b20.

Further, the CPU 1 continuously monitors the elapsed time of the music performance (step b20), and the elapsed time from the start of the music performance is calculated based on the total performance time of the music and the video of the end portion F of the background video data. When it is time to subtract the time, jump from the middle part M of the background video data to the head of the end part F to reproduce the background video data of this end part F (step b21). b
Move to 22.

Further, it is determined whether or not the elapsed time from the start of the music performance has reached the timer value set in step b4, ie, whether or not the music performance time has elapsed (step b22). When the performance time of the music has elapsed from the time of, the performance of the music and the display of the background video are ended (step b15).

In step b22, if the performance time of the music has not elapsed since the start of the performance of the music, the elapse of the performance time at predetermined time intervals (in this example, 30 second intervals) for displaying the score is checked. Monitor (step b2
3) Every 30 seconds, the displayed score is cleared (step b24), and the singer's score for the newly passed 30 seconds is displayed (step b25). Then, the procedure of steps b18 to b22 is performed. Repeat. If NO in step b23, that is, if it is not the timing for displaying the score, the process directly returns to step b18.

If it is determined in step b16 that the set mode is not the scoring mode, it is next determined whether or not the scoring video mode is set (step b26). After clearing the previous scoring result displayed (step b2
6) As in the case of the above-described scoring mode, it is determined whether or not the reproduction of the background video has reached the end of the intermediate portion M (step b28). When the end of the middle part M is reached, the head of the middle part M of the background video data (or the start part S)
Jump to the top of the image) and display the image repeatedly (step b29).

At this time, as described later, if the timing coincides with the timing every elapse of a predetermined time (30 seconds in this example) from the start of the performance of the music, the background video is the video of the angle corresponding to the evaluation of the singing ability. Is switched to and displayed. If it is not the timing for evaluation. Return to the beginning of the video at the same angle.

Further, the CPU 1 continuously monitors the elapsed time of the music performance (step b30), and the elapsed time from the start of the music performance is calculated based on the total performance time of the music and the video of the end portion F of the background video data. At the time when the time is subtracted, the jump from the middle part M of the background video data to the head of the end part F is performed, and the singing ability among the multi-angle (5 angles in this example) of the background video data of the end part F is Is reproduced (step b21), and if not, the process proceeds to step b32.

Further, it is determined whether or not the elapsed time from the start of the music performance has reached the timer value set in step b4, that is, whether or not the music performance time has elapsed (step b32). When the performance time of the music has elapsed from the start, the performance of the music and the display operation of the background video are ended (step b15).

In step b32, if the performance time of the music has not elapsed since the start of the performance of the music, the progress of the performance time is monitored at intervals of 30 seconds (step b33). While switching to the video of the angle corresponding to the evaluation of the singing ability in the elapsed 30 seconds (step b34), steps b28 to b
Repeat step 32. If NO in step b33, that is, if it is not the timing of video switching according to the score, the process directly returns to step b28.
