BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a block diagram showing the configuration of an operation comparing apparatus according to the present invention. FIG. 1 is a block diagram showing an electrical configuration of a karaoke apparatus to which the operation comparison device of the present embodiment is attached. The karaoke apparatus 1 is a so-called communication karaoke in which music information and image information are transmitted via a communication line. In this case, based on the music information and the image information transmitted through the communication line, the user refers to the lyrics displayed on a display means such as a CRT display device and adjusts the microphone according to the performance flowing from the speaker. You can sing a song using. This karaoke device 1
Consists of almost the same configuration as general communication karaoke,
As shown in FIG. 1, a modem 19 connected to the host computer 2 via a telephone line, an input device 10 as an input means for making a reservation of music, etc., a CPU 13 for controlling the karaoke device 1, and a program A control unit including a ROM 14 and a RAM 15, a sound source reproducing device 18 as a performance reproducing unit, an amplifier 20 for amplifying an electric signal related to music information, and an electric signal from the amplifier 20 (corresponding to singing data and performance data to be described later). ) To input accompaniment music and the singing voice of the user, a microphone 23 for inputting the singing voice of the user to the amplifier 20, and an external storage device as storage means for storing music information and image information. 12 and a video playback device 2 for converting image information and the like into a video
4 and a CR for displaying background information and lyrics as image information
And a T display device 26.

The host computer 2 is accessible via a telephone line and has a karaoke device 1 as a terminal.
In response to this, it is possible to manage by transmitting music data such as the latest trendy music and receiving related information such as what music is being played from the outside. Further, the host computer 2 has a database 21,
The database 21 stores a large number of pieces of music information used for music performance, image information such as background images or lyrics, and further, prescribed choreography information (first operation information) described later. Then, the host computer 2 can read out from the database 21 that stores a large number of music information and the like in addition to the latest popular music and the like at any time.

The modem 19 connected to the CPU 13 has C
A modulation / demodulation device that modulates and demodulates a signal under the control of the PU 13. The modulation / demodulation device can access the host computer 2 through a communication line. Thereby, the modem 19
Can receive music data transmitted from the host computer 2 via a telephone line, and can transmit the relevant information to the host computer 2 via a telephone line. In the karaoke apparatus according to the present embodiment, data of a new song is transmitted from the host computer 2 to the CPU 13 via the telephone line at night in order to maintain a state in which the latest song can always be used. Then, data including music information of the new music is stored in an external storage device 12 such as a hard disk. At this time, if the memory of the external storage device 12 such as a hard disk is full, the CPU 13 removes the data of the song that is not frequently used and stores the data of the new song in the external storage device 12, for example. Is configured.

The input device 10 connected to the CPU 13 includes:
An operation unit (operated by the user) for selecting an arbitrary song, adjusting a pitch of a performance sound, adjusting a volume balance between a performance and a song, and performing various adjustments such as an echo, a volume, and a tone. (Not shown). The operation unit is generally of a remote control type, and includes a music number key for reserving a music number as a reservation number. Thereby, the user can make a reservation registration of the music to be reproduced in the karaoke apparatus 1 by remote control via the remote controller.

The external storage device 12 connected to the CPU 13 has a storage area 12f for storing the music information.
And a storage area 12e for storing the image information. Thereby, when a song is selected via the operation unit of the input device 10, the CPU 13 sets the lyrics data,
Image information composed of video data and music information composed of performance data are called out from the storage areas 12e and 12f and output in synchronization with the video reproduction device 24 and the sound source reproduction device 18. Then, the performance data output from the CPU 13 is converted into analog performance data in the sound source reproducing device 18 and then sent to the amplifier 20 to be electrically amplified. Since the amplifier 20 also mixes the singing data of the user input through the microphone 23 at an appropriate ratio, the mixed singing data and performance data are output from the amplifier 20 to the speaker 22, and the voice and performance data are output. The song is output from the speaker 22 to the outside.

On the other hand, the video reproducing device 24 connected to the CPU 13 controls the external storage device 1 under the control of the CPU 13.
2 reproduces an image based on the image information 12e read out from the second information. As a result, the lyrics data output by the CPU 13 is combined with the video data in the video playback device 24 and displayed together with the video on the screen of the CRT display device 26.

Note that a CP for controlling the entire karaoke apparatus 1
U13 is connected to a program ROM 14 and a RAM 15, and the ROM 14 stores a control program of the karaoke apparatus 1 and an operation program of the CPU 13. The RAM 15 can store various flags and the like in addition to storing flags used when a music piece is selected. Since the karaoke apparatus of this embodiment can score the choreography of the user under the control of the CPU 13, the karaoke apparatus can score not only the user's song but also the performance as an evaluation target, and also can score the user's choreography. Choreography can be scored equally regardless of physique.

Next, an operation comparison device attached to the karaoke apparatus of this embodiment will be described. For example, the motion comparison device of the present embodiment includes choreography information (second motion information) relating to various choreography motions of a karaoke user who sings and becomes a singer himself, and each singer performs choreography in a similar state in advance. The specified choreographic information (first operation information) at the time of operation can be compared. Thereby, according to this device,
The difference between the choreography operation of the karaoke user (second operation) and the choreography operation of a singer or the like (hereinafter referred to as a prescribed choreography operation (first operation)) is clarified, and the karaoke user's choreography operation (second operation) is performed.
Of the operation) can be notified to the user. Therefore, the karaoke user can easily understand mistakes and the like related to his or her choreography operation (second operation), and can improve the acting ability and the like of the choreography operation (second operation). In comparing the choreography operation (second operation) with respect to the user and the prescribed choreography operation (first operation) of the singer or the like, the prescribed choreography operation information (first operation) on the choreography operation of the singer or the like (first operation) First operation information)
It is desirable to change to choreography operation information (third operation information) for the user in consideration of the physique and the like of the karaoke user. This is because the operation comparison device compares the choreography operation (second operation) relating to the karaoke user with the prescribed choreography operation (first operation) of the singer or the like. This is because it is difficult to discover various erroneous choreographic operations or the like simply by comparing the choreographic information (second operational information) and the prescribed choreographic information (first operational information). Therefore, the CPU 13 converts the prescribed choreography information (first operation information) into body part ratio information (fourth information).
Based on the above, it is possible to change to the third choreographic information for the user, that is, the estimated choreographic information assuming the choreography in consideration of the physique of the user.

Specifically, the external storage device 12 includes a storage area 12a as first information storage means for storing the prescribed choreography information (first information), and the choreography information (second operation information). And a storage area 12b (third information storage means) for storing estimated choreography information (third operation information for a user). Storage for storing body ratio information (fourth information) such as the physique of a karaoke user, which is used in changing the prescribed choreography information (first movement information) to third movement information for the user. And an area 12c (fourth information storage means). Then, the CPU 13 may store the storage area 12a for storing the specified choreography information, the storage area 12b for storing the choreography information, and the storage area for storing the body part ratio information, if necessary, from the external storage device 12 as storage means. 12c, storage area 12 for storing estimated choreography information
d, the respective data can be called from the storage area 12e for storing the image information and the storage area 12f for storing the music information.

In this case, the CPU 13
a and 12d have a function of calling the first operation information and the third operation information stored in the storage area 12d and comparing the first operation information and the third operation information with each other.
a, a function of calling the first operation information and the second operation information stored in 12b and comparing the first operation information and the second operation information with each other. Become. Thereby, the CPU 13 sets the storage area 12a,
Since the first and second operation information or the first and third operation information stored in 12b and 12d can be called and these operation information can be compared with each other, the user can use the first and second operation information. 2 of the operation information or the first and third
Can be easily grasped.

Next, choreographic information constituting the first, second, and third operation information will be described. This choreography information is shown in FIG.
As shown in FIG. 5, sensors 41, 42, and 43 attached to the left wrist, the center of the top of the head, and the right wrist of the karaoke user located on the mat 28, and the contact position 44 of the left foot tip and the right foot tip , 45 in the X-axis direction, Y-axis direction, and Z-axis direction. However, the mounting position of the sensor is not limited to that position, and many sensors can be mounted at various other positions.

In this case, for example, the mat 28 made of an electromagnetic mat is configured like a touch panel capable of detecting the position information of the coordinate values of the Y axis 47 and the X axis 46. Therefore, as shown in FIG. 2, the mat 28 connected to the CPU 13 uses the position information of the ground contact position 44, which is the contact surface of the mat 28, that is, the position information of the coordinate values of the Y axis 47 and the X axis 46 as C
It is configured to output to the PU 13. The sensors 41, 42, and 43 are light-emitting / light-receiving sensors that emit light linearly to the surroundings, and light that is linearly reflected by the peripheral walls 49 and 50 of the light emitted to the surroundings. When the sensors receive light, these sensors 41, 42, 43
The position can be detected. As a specific example, the sensor 41 is connected to the CPU 13 similarly to the sensors 42 and 43, and as shown in FIG.
8 and the surrounding walls 49, 5
The position of the sensor 41 measured by the reflection by 0 is represented by Y
As position information of the coordinate values of the axis 47 and the X axis 46, the CPU 1
3 is output. Therefore mat 2
8. The sensors 41, 42, and 43 constitute a choreography information acquisition unit.

Therefore, according to such a choreography information acquiring means, for example, a hand that is a basic choreography for a user,
A sensor is attached to a part of the head, and furthermore, the user's hand, the choreography position of the head, and the standing position of the user in the mat can be acquired from the mat that shows the position where the user touches the ground. However, as long as the choreographic information can be processed by the CPU 13, the choreographic information may be obtained by another method. For example, the sensors 41, 42, 4
Reference numeral 3 may be a transmission type sensor that emits a radio wave to the surroundings.
These receivers may detect the position of the sensors 41, 42, 43 by receiving a plurality of receivers (not shown) attached to the sensors 9, 50. Further, as the position information of the user's choreography, a state in which the user's choreography is performed may be taken by an imaging device such as a fixed camera, and the user's position information may be obtained from the video.

In the case of FIG. 2, the confirmed position of the sensor 41 is represented by a numerical value as shown in FIG.
50, Y1 = 50 and Z1 = 60. Also, the sensors 42 and 43 can be similarly displayed as numerical values. Further, as described above, the mat 28 can detect the positions in the X-axis direction and the Y-axis direction.
The position in the axial direction can be detected. In addition, mat 28
The position information in the Z-axis direction becomes 0 and becomes reference information.

The sensors 41, 42, 43 and the contact positions 44, 45 can be defined as three-dimensional position information in the X-axis direction, the Y-axis direction, and the Z-axis direction with the origin at the left corner of the mat 28. Thereby, for example, the sensors 41, 4
2, 43, and the contact information of the contact positions 44 and 45 are (X1,
Y1, Z1), (X2, Y2, Z2), (X3, Y3,
Z3), (X4, Y4, 0), and (X5, Y5, 0), the choreographic information created based on these positional information has extremely high objectivity. Note that the prescribed choreography information (first operation information), which is information when each singer has performed a choreography operation (first operation) in the same state in advance, is also performed in the X-axis direction and the Y-axis direction by the same method. , 3 in the Z-axis direction
Created as dimensional position information. The specified choreography information (first operation information) is created in advance and stored in the database 21 in large numbers. If necessary, it is stored in the storage area 12a of the external storage device 12.

Next, the body part ratio information stored in the storage area 12c will be described. When the CPU 13 compares the choreography operation (second operation) of the karaoke user with the choreography operation of the singer or the like (first operation), the karaoke user and the singer naturally have different physiques. Choreography information (second motion information) and specified choreography information (first motion information) including three-dimensional position information in the X-axis direction, the Y-axis direction, and the Z-axis direction are transferred in the X-axis direction, the Y-axis direction, and the Z-direction. It is difficult for a user to discover various mistakes in choreography operation or the like simply by comparing the three-dimensional directions in the axial direction. Therefore, the CPU 13
Third for user based on body ratio information (fourth information)
The three-dimensional position information in the X-axis direction, the Y-axis direction, and the Z-axis direction, which has been changed to the motion information, is assumed. As a result, the CPU 13 serves as a changing unit.

However, when comparing the choreography operation of the same person with respect to the karaoke user before and after the practice of the choreography operation, since the physiques have the same physique, the storage area 1
There is no need to use the body part ratio information stored in 2c.
In this case, the first motion information is a choreography motion after the choreography motion practice, and is stored in the storage area 12a as the first information storage means, and the second motion information is
The choreography operation is performed before the practice of the choreography operation, and is stored in the storage area 12b as the second information storage means.

Specific body part ratio information can be obtained as follows. For example, as shown in FIG. 8A, the head H1, the neck N1, the right shoulder RS1, the left shoulder HS1, the left elbow LE1, the right elbow RE1, the left wrist LW1, the right wrist RW1, the left tip LH1, and the right hand related to the singer. Tip RH1, abdomen W1, left thigh LT1, right thigh RT1, left knee LK1, right knee RK1,
Left ankle LA1, right ankle RA1, left toe LB1, right toe R
Three-dimensional position information in the X-axis direction, the Y-axis direction, and the Z-axis direction related to B1 is acquired in advance. Next, as shown in FIG. 8B, the head H2, the neck N2, the right shoulder RS2, the left shoulder HS2, the left elbow LE2, the right elbow RE2, the left wrist LW2, the right wrist RW2, and the left tip of the karaoke user. LH2, right hand RH2,
Abdomen W2, left thigh LT2, right thigh RT2, left knee LK2,
Right knee RK2, left ankle LA2, right ankle RA2, left toe LB
2. Acquire three-dimensional position information of the right toe RB2 in the X-axis direction, the Y-axis direction, and the Z-axis direction.

Thus, the heads H1 and H2, the neck N1 and N2, the right shoulder RS1 and 2, the left shoulder HS1 and 2, the left elbow LE1 and the left elbow RE1, and the right elbow RE1 for the karaoke user and singer.
And 2, left wrists LW1 and 2, right wrists RW1 and 2, left hand LH1 and 2, right hand RH1 and 2, abdomen W1 and 2, left thigh LT1 and 2, right thigh RT1 and 2, left knee L
K1 and 2, right knee RK1 and 2, left ankle LA1 and 2,
Right ankle RA1 and 2, left toe LB1 and 2, right toe RB
When the three-dimensional position information of the X-axis direction, the Y-axis direction, and the Z-axis direction regarding 1 and 2 are compared, the three-dimensional position information is naturally different. Information can be obtained.

Specifically, the heads H1 and H2 shown in FIG.
In the case of, the height of the singer is 175 cm and the height of the karaoke user is 155 cm based on the position information in the Z-axis direction obtained from the sensor 42), and the ratio is 0.83.
(The singer's height is 1). Therefore, comparing the positional information on the head H1 of the singer with the positional information on the head H2 of the karaoke user, the body ratio information on the height difference can be obtained. (Information), it is possible to change (correct) the third operation information for the user. Specifically, the height of the singer is 175 cm, and the height of the karaoke user is 155 cm.
In the case of cm, the ratio of the height of the singer to 1 is 0.83, and therefore, as shown in FIG.
By multiplying the information on the axial position by the ratio 0.83, the information on the Z-axis correction ratio can be obtained.
As for No. 3, information on the Z-axis correction ratio can be obtained.

Similarly, information on the correction ratio in the X-axis direction and the Y-axis direction can be obtained as follows, for example. 1) Information on the position of the singer's head H1 in the X-axis and Y-axis directions (position information in the X-axis and Y-axis directions obtained from the sensor 42,
2) Information on the position of the user's head H2 in the X-axis and Y-axis directions (X-axis and Y-axis position information obtained from the sensor 42,
That is, x2 and y2) are used as references. 3) Information on the position of the singer's left wrist LW1 in the X-axis and Y-axis directions (position information in the X-axis and Y-axis directions obtained from the sensor 41, ie, X1, Y1) 4) The left wrist of the user Information on the position of the LW2 in the X-axis and Y-axis directions (position information in the X-axis and Y-axis directions obtained from the sensor 41, i.e., x1, y1) 5) Then, the "difference between X1 and X2" Assuming that it is 1, the ratio of “difference between x1 and x2” and “Y1 and Y2”
When the "difference from 2" is set to 1, the ratio between "the difference between y1 and y2" can be used as the correction ratio information. 6) The information on the correction ratio is stored in the storage area 12c. However, the correction ratio may be obtained by other methods. The body ratio information (fourth information) for each singer is created in advance and stored in the database 21 in large numbers. If necessary, the information is stored in the storage area 12c or the like of the external storage device 12. .

The obtained choreography information and the estimated choreography information comprising the prescribed choreography information, that is, the estimated choreography information assuming the choreography in consideration of the user's physique with respect to the prescribed choreography information. The operation of the karaoke apparatus provided with the operation comparison device capable of comparison will be described with reference to the flowcharts of FIGS. FIG. 3 is a flowchart showing the song reservation processing in the karaoke apparatus 1.
First, in S1, the CPU 13 inputs song number data from the input device 10 to select a song, and if there is an empty space for song number reservation in the song number memory on the RAM 15 (N in S2).
O), the input music number is stored in the music number memory (S)
3). On the other hand, if there is no free space in the music number memory of the RAM 15 (YES in S2), the CPU 13 rejects the reception of the music number data and returns to S1 (S4). CPU 13
Determines whether or not to end in S5. If YES, the process ends. If NO, the process returns to S1.

FIG. 4 is a flowchart of a karaoke performance process which is executed when the CPU 13 receives a reserved song. First, in S10, if the music number of the performance music is stored in the music number memory of the RAM 15, the CPU
In S11, in S11, the first music number data of the music number data stored in the music number memory is read.
In S12, the CPU 13 stores the specified choreography information as shown in FIG.
The specified choreography information acquired by communicating with the storage area 12a (may be stored in the RAM 15 if necessary, or may be stored only in the RAM 15 instead of the storage area 12a). (S12).

Further, the CPU 13 displays a screen as shown in FIG. 5 in order to obtain the position information of the user (S1).
3) Acquire the position information. And the CPU 13
Is body part ratio information as shown in FIG. 7 (fourth information)
Is created and the body part ratio information (fourth information) is stored in the storage area 1
2c (S14). The CPU 13 calculates the estimated value of the choreography estimated to move when the user performs the choreography from the body part ratio information (fourth information) created in S14 in the same manner as in FIG. 6 based on the prescribed choreography information. Created in a simple format and stored in the storage area 12d of the external storage device 12 as estimated choreography information (third operation information for the user) (S1).
5). Further, the karaoke data corresponding to the song number is read from the external storage device 12, the estimated choreography information created in S15 is read from the storage area 12a, and the karaoke performance is executed (S16, S17, S18).

During a karaoke performance, the CPU 13 performs choreography information (second operation information) for each choreography of specified frames from the sensors 41, 42, 43 and the grounding positions 44, 45 worn by the user as shown in FIG. Is acquired and stored in the storage area 12b (S19). The CPU 13 executes S1 as choreography comparison means.
5 is compared with the information acquired in S19, and the difference between the information is written in the RAM 15 (S2).
0).

When the karaoke performance ends, S21 to S
22, the body part ratio information (fourth information), the estimated choreography information (third operation information for the user), and the prescribed choreography information (first
Is deleted from the storage area 12a (S22).
The difference values written in the RAM 15 in S20 are totaled and calculated as a scoring score (S23), and the scoring result, that is, the comparison result of the CPU 13 as the comparing means, is displayed on the CRT display device 26 (S24). As described above, the CPU 13 as the choreography comparison unit can score the choreography by comparing the prescribed choreography information with the choreography information. Next, the music number memory on the RAM 15 is shifted (S25), and it is determined whether or not the karaoke performance processing for one music is finished (S26). If YES in S26, the process ends, and if NO, the above mode is repeated.

In the above embodiment, the choreography information employs a motion comparison device having estimated choreography information assuming choreography in the case of a user's physique with respect to the prescribed choreography information. There are the following effects (1) and (2). In other words, (1) If the singer is clearly different from the singer himself, even if he / she attaches a sensor to the user's hand, which is the basis of choreography, and a sensor on a part of the head, the scoring standard will be significantly different at that time. The singer deviates from the prescribed choreography information, causing a difference. Therefore, no matter how correct the choreography of the user is, the user whose physique is clearly different from the singer himself may have a poor scoring result. However, the prescribed choreography information is predicted in the case of the user's physique, and information assuming the position of the choreography is calculated as the estimated choreography information,
By making it a comparison target, it becomes possible to perform equal choreography and scoring regardless of the user's physique. (2) In the karaoke apparatus equipped with the operation comparison device, the choreography can be graded, so that the user can score not only the song but also the performance as an evaluation target. This is because while there are many karaoke users who sing as they are, the conventional karaoke device with a scoring function,
While choreography is not scored, it is a much better karaoke device. In other words, many of the songs sung in karaoke are often choreographed. Although it is difficult to say that the performance is sufficiently satisfied, according to the present karaoke apparatus, the performance can be scored as an evaluation target, and the satisfaction of the user can be sufficiently satisfied.

As is apparent from the above description, according to the karaoke apparatus provided with the operation comparing device of the present embodiment, the storage area 12a for acquiring and storing the prescribed choreography information (first operation information). , A storage area 12b for acquiring and storing choreography information (second operation information);
a, 12b (prescribed choreography information (first operation information) stored in the first information storage means and the second information storage means)
And a CPU 13 that calls up the choreography information (second operation information) and compares the prescribed choreography information (first operation information) and the choreography information (second operation information) with each other. Thereby, the CPU 13 can compare the specified choreography information and the choreography information (first and second operation information) with each other,
A user using this apparatus can know the difference between the prescribed choreography information and the choreography information (first and second operation information), and can grasp the problem. As a result, for example,
