ABSTRACT:
BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates to a method and an apparatus for selecting a harmonic color using the harmonics, and a method and an apparatus for converting sound to color or color to sound, and more particularly to a method and an apparatus capable of converting a sound into a color image or an image into a sound, by selecting the harmonic color exactly tuned with an optional reference color based on the harmonics, and frequency conversion of a sound or a color having a characteristic of wave.
2. Description of the Related Art
According to the popularization of color due to the color television broadcasting, the economical value of the color is increased. Accordingly, it is very important for web designers, artists, architects, interior decorators, industrial designers, landscape architects, dress designers, stage directors, creators of various fields, and purchasers to select the harmonic color.
The term ‘color harmony’ means two or more colors are used in close to each other to give a good effect.
According to the conventional color harmony, the harmony color is selected by reference to a book printed in a color of which an optional reference color is printed and the harmony colors harmonizing with the reference color are printed as a natural color based on visual experience of human. The standard of representative color harmony is a Coloring Book, a Munsell Colorimetric System, and CIE Standard Colorimetric system.
However, the conventional lacks of objectivity in that the method is based on the human experience or the experiment. Because the harmony color is selected by the visible sense by reference to the printed reference material, the accuracy of the color may be reduced. In addition, it is impossible to use the printed reference for a Desk Top Publishing system using a computer.
In a converting method sound to color deriving the harmony color from the harmony music, the color and the sound are different to the band of frequency adapted to the sense of sight and hearing, but are identical to the property of physical wave. However, it has not been studied on the reversible conversion of the color and the sound.
The conventional sound pressure displaying apparatus which is representative of a graphic equalizer visualizing the change of the sound displays only magnitude of the sound pressure each a band of frequency, thereby providing a disadvantage of simply displaying the image and limiting the application range.
U.S. Pat. No. 6,046,724 issued to Havass discloses a method and an apparatus for the conversion of sound waves to light. According to the Havass patent, the light matching a sound is displayed by controlling three color light sources of RGB based on each frequency and the magnitude of the sound through 6 filter means corresponding from 3 octave to 8 octave.
SUMMARY OF THE INVENTION
Therefore, a major object of the invention is to solve the problems involved in the related art, and to provide a method and an apparatus capable of selecting the harmonic color exactly tuned with an optional reference color based on the harmonics.
Other object of the invention is to provide a sound/color converting table capable of easily seeing the conversion of sound and color, in which 12 musical scale degrees and 12 color system corresponding to 10 octave and 10 luminance are arranged on a first coordinate axis in a relationship of 1:1.
The other object of the invention is to provide a musical instrument capable of recognizing the color in a scale degree by coloring the scale degree position based on the sound/color converting table.
Another object of the invention is to provide objective and credible systematic frequency conversion criterion using wave of color and sound, that is, frequency characteristics to provide a method and an apparatus capable of converting a sound into a color image or an image into a sound by converting visual and audible frequency into audible and visual frequency based on the above criterion.
Still another object of the invention is to provide a method and an apparatus of determining a sound source position to display the stereo sound source position in sound/color conversion.
The other object of the invention is to provide a musical instrument capable of recognizing the color in a scale degree by coloring the scale degree position based on the sound/color converting table.
The musical scale degree dividing rate is any one of an average rate or a just temperament. In case of average rate, the harmony color can be obtained as following equation:
F
h
=F
r
×(
k
{square root over (2)})
n
wherein, Fh denotes a harmony frequency to be obtained, Fr denotes an input frequency, k denotes the number of the musical scale degree which is resulted from dividing a frequency of one octave by a constant rate, n denotes a harmony frequency ratio and 1≦n≦(k−1), in which k and n are natural number.
In other aspect of the present invention, there is provided an apparatus of selecting a harmony color comprising: means for selecting the musical scale degree dividing rate, a harmonics code, and a reference color; means for storing a table of the harmony frequency ratio of the harmony scale degree by the harmonics code according to the musical scale degree dividing rate; means for operating a luminance of the selected reference color, determining an octave corresponding to the luminance, and operating a frequency of the harmonic color from the referenced frequency by reference to a harmony frequency ratio of the selected harmonics code in the table, and, if the operated harmonic color frequency is deviated from a band of visible frequency, converting the harmonic color frequency into the band of visible frequency and then displaying the operated harmonic color frequency as the referenced harmonic color.
In the other aspect of the present invention, there is provided a sound/color converting table, wherein 12 musical scale degrees and 12 color system as 12 equivalent width are arranged on a first coordinate axis in a relationship of 1:1 by setting ‘do’ of musical scale degree and ‘red’ of a color system to an original point of the coordinates, and 10 octaves and 10 luminance are arranged on a second coordinate axis in relationship of 1:1. The sound/color converting table is any one of circular coordinate system and orthogonal coordinate system. A ‘red’ of the color system has a wavelength of which ‘do, mi, sol’ of the musical scale degree is approximate to ‘red, green, blue’ of the color system.
The circular coordinate system is set that the first coordinate axis is in a direction of circumference, and the second coordinate axis is in a direction of a center of circle.
The orthogonal coordinate system is made in such a way that the luminance is in direct proportion to the musical scale degree.
In another aspect of the present invention, there is provided a musical instrument which corresponds to the musical scale degree position being colored by a sound/color converting table.
In still another aspect of the present invention, there is provided a method of converting a sound to a color, the method comprising the steps of: Fourier-transform of sound source; sampling at least one signal of particular audible frequency among the Fourier-transformed signals; converting at least one sampled signal of the audible frequency into a signal of a visible frequency using following equation; and displaying a color corresponding to at least one converted visible frequency:

F is a visible frequency to be obtained, Fl is a reference visible frequency, a positive number of x is a value of octave, BF is a luminance of color, x* is places of decimals and denotes a height of sound in one octave, fi is a sampled audible frequency, fl is a reference audible frequency, C′ is a constant and denotes a real number between 0≦C′≦1.
The sampling step includes the steps of inputting the Fourier-transformed signal every a
