Abstract

PURPOSE:To visually enjoy emotional expression that music has by converting music information read out of a music storage medium into image information and displaying it as an image output. CONSTITUTION:The sound signal outputted from a CD player 1 is inputted to a converting circuit 4 and converted here into an image signal. This conversion is carried out so that the pitch, loudness, and timbre variations of the sound correspond to the hue, brightness, and saturation variations of an image, and the image is passed through a0 image output circuit 5 and displayed on a CRT display device 6. Therefore, when variation of the image on the CRT display device 6 is viewed, exactly the same variation as the variation of the sound of the music is obtained. Then when the music from a speaker 3 is listened to as BGM(background music), the variation of the image on the device 6 seems to be BGV(background video) and makes a listener feel comfortable.

Description

Detailed Description of the Invention

[0001]

This invention relates to a music CD, DA
The present invention relates to a music information / image information conversion device that converts music output from music information storage media such as T, MD, LP records, open reels, and cassette tapes into image information, and an image changes based on the music information.

[0002]

2. Description of the Related Art Conventionally, for listening to music, music is stored in a music CD, a cassette tape, an LP record, etc., and the music read from these is output from a speaker and played back. Stores images in an image storage CD or the like, and displays and reproduces the images on a two-dimensional display device such as an LCD. These music CDs and image display LCDs exist separately, and their reproducing devices are also separate in terms of mechanism and circuit configuration.

[0003]

As described above, the music CD for listening to music and the LCD for listening to images are separate, and when enjoying music with the music CD, the music CD is used. The music stored digitally in the above was merely to enjoy the sound output through a speaker or the like.

However, as shown in FIG. 2, music and abstract images are very similar in terms of their constituent factors and characteristics, and it is possible to convert music information into a kind of abstract image. If the image changes according to the melody of the music while outputting, it is possible to enjoy music in a broad sense by the movement, that is, the moving image.

The present invention has been made in view of the above problems, and it is an object of the present invention to provide a music information / image information conversion apparatus that allows users to enjoy and enjoy the emotional expression of music.

[0006]

According to the music information / image information conversion apparatus of the present invention, there is provided a music storage medium storing the music information, and a reading means for reading the music information from the music storage medium. Music / image conversion circuit means for converting the music information into image information and two-dimensional display means for displaying the converted image information.

In this music information / image information conversion device, when music information is read from a music storage medium, for example, a music CD, and output, this music information is converted into image information by the music / image conversion circuit means. It is converted and given to a two-dimensional display means such as an LCD. The two-dimensional display means changes the extracted display image according to the information of the music, that is, the information.

[0008]

The present invention will be described in more detail with reference to the following examples. FIG. 1 is a block diagram of a music information / image information conversion apparatus showing an embodiment of the present invention. This music
The image generation device includes a CD player 1, an audio amplifier 2, a speaker 3, a conversion circuit 4, an image output circuit 5, and a CRT display device 6.

The CD player 1 is a well-known one, in which a music CD is set and the music stored in the CD is reproduced. The conversion circuit 4 is
The frequency band of a normal music signal is at most several 10 Hz.
Since it has only several tens of KHZ, it has a function of including a conversion circuit and extending the frequency band from 0 to several MHZ through it. Further, after the expansion for each frequency band, it is converted to an abstract image signal through an appropriate circuit for amplification, attenuation, modulation and the like. Further, in the conversion circuit 4, the degree of amplification, attenuation, modulation, etc. can be arbitrarily adjusted by the viewer according to his hobby.

In the music information / image information conversion apparatus of this embodiment, when the apparatus starts to operate, the CD player 1 outputs the sound signal of the music stored in the CD, which is amplified by the audio amplifier 2 and the speaker. It is pronounced from 3. This operation is similar to the conventional one. The sound signal output from the CD player 1 is also input to the conversion circuit 4, where it is converted into an image signal. This conversion is performed in response to changes in tone pitch, intensity, and tone color as changes in the hue, brightness, and saturation of the image.
It is displayed on the T display device 6. Therefore, when the change in the image on the CRT display device 6 is visually observed, the change in the sound of the music is exactly the same, and the music output from the speaker 3 is BGM.
In the case of (background music), the change in the image on the CRT display device 6 makes the viewer feel good as if it were BGV (background video).

The CRT display device used in the above embodiment may be an ordinary television receiver of each home, but the present invention is not limited to this, and other than the two-dimensional display means itself and the CRT. You can use other principles such as LCD (Liquid Crystal Display) panel, and you can view the concert by inputting it to a large projector, laser projector, or other light output device instead of a small number of people. Even in such cases, it is possible to provide the public with abstract images, abstract rays, etc. that change in accordance with music.

[0012]

According to the present invention, music information read from a music storage medium is converted into image information and displayed as image output.
While there is a comfortable sound output called GM, you can enjoy the color image output that changes the color tone, light and shade, shape, etc. according to the content that the music is trying to express emotion when listening to this music. It will be more fun. In addition, it is possible to make people who have a hearing loss enjoy what the music is trying to express.
