Next, as shown in FIG. 10, a description will be given of a graphic image whose display is converted according to a change in a three-dimensional parameter such as a frequency, a level of the frequency, and time (change with time). Here, the first parameter is frequency, the second parameter is frequency level, and the third parameter is time. The graphic image generating unit 8 corresponds to the first, second, and third parameters. The graphic image displayed three-dimensionally is converted according to the change of each parameter.

FIG. 11 shows the frequency level f of each frequency f.
_L shows the graphic image representing the change and its frequency level at each time.

The above-mentioned frequency level is expressed in the form of a bar graph, and its length expands and contracts according to the increase and decrease of the corresponding frequency level. In addition, regarding the expression of a graphic image showing the temporal change of the frequency level,
For example, it is created so that the frequency level displayed at the previous time is shifted in the time axis direction. For example, the frequency level newly obtained in time is displayed from the back side in the direction perpendicular to the paper of FIG. 11, and the frequency level obtained at the previous time is displayed before the newly obtained frequency level, that is, in the direction perpendicular to the paper of FIG. Expressed to be displayed on the near side. Such a display procedure is performed until time T _{n + 1} , that is, time T _{n + 2}
The display of the frequency level of time T _{n + 3} is shifted to the position where the frequency level of time T _{n + 3} was displayed, and the display of the frequency level of time T _{n + 2} is displayed at the position where the frequency level of time T _{n + 1} was displayed. It is shifted, for the frequency level of the time T _n, cancel the display.

By creating a graphic image using the third parameter as a time axis, for example, a wave which rises or falls like a wave rushing and which depends on the frequency level is expressed. You.

Here, for example, by displaying a graphic image as shown in FIGS. 12 and 13, it is possible to more specifically express how the waves hit.

As shown in FIG. 12, the height of a wave is represented by a curved round bar 30, and the length of the curved round bar 30 is expanded and contracted by a change in frequency level. Here, the round bar 30 becomes longer by increasing the frequency level, and becomes smaller by decreasing the frequency level.
Try to be shorter.

Regarding the third parameter, FIG.
As described above, the frequency level displayed at the previous time is shifted in the time axis direction, that is, the frequency level newly obtained in time is displayed from the back side in the vertical direction on the paper, and the The obtained frequency level is shifted and displayed before the newly obtained frequency level, that is, toward the near side in the direction perpendicular to the paper surface.

With this expression, the graphic image is displayed as shown in FIG. Specifically, in FIG. 13, the level change of each frequency is shown in the horizontal direction of the paper, and for example, the round rods 30 ₁₁ and 3 which are curved are shown.
Numerals 0 ₂₁ , 30 ₃₁ , 30 ₄₁ , and 30 ₅₁ express the change in the frequency level of each frequency obtained at the same time by its length. Then, 13 shows the time course of frequency levels to the paper surface direction front-rear direction, for example, a round bar 30 ₁₁ curved, 30 _12, 30 _13, 30 _14, 30
Reference numeral ₁₅ denotes a change with time of the frequency level of the same frequency.

By creating the graphic image in this way, the frequency level and the change with time of the frequency level can be displayed in an expression as if a wave is coming.

As described above, the display / reproduction unit 3 can generate a three-dimensional graphic image corresponding to the frequency level, volume and time of the sound. Therefore, the display unit 2
, The change of the sound parameter of the music information is displayed as a three-dimensional graphic image.

Next, a description will be given of a process of changing a graphic image according to a sound parameter of the music information during reproduction of the music information.

First, as shown in step S1, a music piece is designated by the reproducing apparatus 1. That is, the reproducing device 1 specifies the music information recorded on the disk of the recording unit 7 according to the reproduction command input from the input unit 9. Then, in step S2, the reproducing device 1 reproduces the specified music information.

Subsequently, in step S3, the control section 6 of the reproducing apparatus 1 analyzes the frequency of the sound of the reproduced music information by FFT. Then, in response to the obtained analysis result, that is, the change of the first, second, and third parameters, the graphic image generating unit 8
The character (graphic image) is converted and displayed on the display unit 2.

In the following step S5, the reproduction apparatus 1
Determines whether the reproduction of the music has ended. Here, when it is confirmed that the reproduction of the music has ended, the reproducing device 1 ends the conversion and display processing of the graphic image. If it is confirmed that the reproduction of the music has not been completed, the reproducing device 1 returns to the process of step S3, and again converts the graphic image according to the frequency of the sound of the reproduced music information. And display processing.

According to the procedure shown in FIG. 14, a graphic image is converted in accordance with the music during reproduction of the music, and the graphic image is displayed on the display unit 2.

It should be noted that the display form of the graphic image on the display unit 2 can be changed. That is, for example, the above-described star-shaped character 20 is displayed while being rotated. In this case, the shape of the character 20 changes according to the change of the sound parameter while being rotated.

In the reproducing apparatus 1, character data is distributed from the information center 11 as described above. Here, as described above, the character data distributed from the information center 11 is basic data for creating a graphic image, that is, the reproduction device 1
Displays, on the display unit 2, a character obtained by converting a change in sound frequency or the like into a change in shape based on character data distributed from the information center 11 as a graphic image. That is, the character data which is the basis of the star-shaped character 20 as described above is stored in the information center 1.
1, the reproduction device 1 displays on the display unit 2 a character 20 that is changed according to a change in sound frequency or the like based on the distributed character data.

Next, transmission of character data from the information center 11 to the reproducing apparatus 1 will be described with reference to FIGS. FIG. 15 shows a series of processes relating to the reception of character data on the playback device 1 side. FIG. 16 shows a series of processes related to transmission of character data on the information center 11 side.

The reproducing apparatus 1 determines whether or not a command to transmit character data has been issued to the information center 11, as shown in step S11 of FIG. For example,
The playback device 1 determines whether the user has requested transmission of character data by detecting the operation state of the input unit 9.

Then, the reproducing apparatus 1 confirming that the transmission command of the character data has been issued transmits a request signal for transmitting the character data to the information center 11 as shown in step S12, Then, in step S13, the process enters a state of waiting for reception of character data transmitted from the information center 11. That is, the reproducing device 1 determines whether or not the character data has been received.

Here, by confirming that the character data has been received, the reproducing apparatus 1 proceeds to step S14 and accumulates the received character data. For example, the character data is stored in a storage unit of the character display conversion unit 8 together with other character data.

The reproducing apparatus 1 selects the character data thus stored in step S15, and determines in step S16.

On the other hand, in the processing relating to the transmission of character data by the information center 11, as shown in FIG. 16, first, in step S17, it is determined whether or not a request signal has been received. That is, step S in FIG.
At 12, it is determined whether or not a request signal for transmitting the character data transmitted by the reproducing device 1 has arrived.

The information center 11, which has confirmed that the request signal has been received in step S17, searches for character data requested to be transmitted by the request signal in step S18. Then, in step S19, the information center 11 transmits predetermined character data. As a result of this transmission, the reproduction device 1 confirms that the character data has been received in step S13 in FIG. 15 and starts processing such as storing the received character data.

As described above, the reproducing apparatus 1 can perform the processing of receiving the character data transmitted from the information center 11 by the processing shown in FIGS. Then, the reproduction device 1 creates a three-dimensional graphic image that changes in accordance with a change in the frequency of the sound of the music information to be reproduced, based on the character data, by the processing shown in FIG. can do.

Therefore, the reproducing apparatus 1 can display the change of the sound parameter of the reproduced sound information on the display unit 2 simultaneously and as a three-dimensionally displayed graphic image.

Thus, the user can visually recognize the change in the parameter of the tune being reproduced, and can easily confirm the change in the sound. And
