When the first pattern and the second pattern are generated, the control unit 130 of the mobile terminal 100 modifies the first image information according to the first pattern and the second pattern based on the first image information selected by the user, 2 image information.

Here, the second image information may be generated in a plurality of ways such that at least one of the shape, color, and motion of the object included in the first image information selected by the user is transformed according to the first pattern and the second pattern, Each identification number can be added so that they can be individually identified.

More specifically, as shown in FIG. 5A, the first image selected by the user can be generated as the respective second image information by the first pattern and the second pattern, wherein each second image information is different An identification number is added, and at least one of shape, color, and operation of the object included in the image information is generated so as to be modified but different from each other as shown in FIG. 5B.

In the present embodiment, it is assumed that the first pattern and the second pattern are generated when the height of the waveform rises or falls for convenience of explanation. However, the pattern generation process can be performed in a more complicated and various ways .

More specifically, for example, generating a plurality of patterns not only utilizes relative size (dB) information obtainable from acoustic information, pitch information of pitch and pitch information, but also amplitude and / A first detection information obtained by detecting the frequency, a first detection information obtained by converting the waveform of the acoustic information into a Fast Fourier Transform (Fast Fourier Transform) method, and a second detection obtained by detecting the inflection point of the waveform of the sound information The plurality of patterns may be generated using at least one or more pieces of information.

For example, in a case where the speech information of the speaker is included in the acoustic information, it is also possible to detect repeated changes of the pitch of the speech range or the pitch of the speech by using the speech information of the speaker, Can be generated.

As another example, it is possible to divide the sound information by a predetermined time or interval unit, detect the inflection point of the first waveform existing in each of the divided pieces of sound information, digitize the detected result, A plurality of patterns can be generated using the detected result by a method of detecting a certain pattern.

As another example, it is possible to divide the sound information by a predetermined time or interval unit, to detect the amplitude and the frequency of the first waveform of each divided sound information, to detect the amplitude of the first waveform of the detected sound information A plurality of patterns can be generated by using the detected result in a manner that a size is quantified and a certain pattern is detected from each digitized result.

Specifically, for example, in the case where the first image information is deformed according to a plurality of patterns generated by using the above-described methods, for example, as shown in Fig. 7A, The second image information can be generated as shown in FIG. 7B by modifying the growth rate and growth direction of the branches of the first image information, respectively.

The visualization method of the sound according to the present embodiment can also use various digital image information such as a raw file, a jrg file, a jpg file, and a png file.

8A and 8B are views illustrating a process of generating second image information for visualizing sound in a sound visualization method according to another embodiment of the present invention.

Hereinafter, the second image information in the visualization method of sound according to the present embodiment, which is different from the process of generating the second image information in the sound visualization method according to the embodiment described above with reference to FIGS. 8A to 8B, Will be described.

The process of generating the second image information in the sound visualization method according to the present embodiment is also the same as the above-described process of generating a plurality of patterns, and the process of generating a plurality of patterns will be omitted.

The process of generating the second image information in the method of visualizing sound according to the present embodiment is not limited to generating the second image information in which the first image information is different according to each pattern when a plurality of patterns are generated, When the patterns are repeatedly arranged as shown in FIG. 8A, the patterns are reflected on the first image information arranged in the order of the arranged patterns, so that the first image information is deformed to generate the second image information can do.

For example, the first image information may reflect the first pattern arranged first to generate the second image information, the generated second image information may be stored, and the stored second image information may be stored in the second 2 pattern is reflected and the new second image information is generated repeatedly. The generated second image information is stored, and the stored second image information is reflected again to reflect the respective patterns New second image information is generated in which the pattern is reflected in the existing second image information and is modified.

Accordingly, a plurality of second image information different from each other can be generated by being deformed once each of the patterns is reflected on the basis of the first image information, 2 image information according to an embodiment of the present invention, it is possible to generate a larger number of second image information than the method of visualizing sound according to an embodiment, in which the first image information and the plurality of second images are continuously It has the merit of being able to express more variously in visualization.
