2. Description of the Related Art In general, a sound reproduction device configured to mix an audio signal mainly composed of musical instrument sounds with an audio signal from a microphone and reproduce the mixture through a speaker requires a lyrics book separate from the device itself. When singing a song, you have to look at this lyrics book while singing, so in addition to selecting a song from a tape or record, you have to select the lyrics that correspond to the selected song from the lyrics book. There was a sense of dignity. Therefore, in addition to reproducing the audio signal mixed with the audio signal from the audio signal microphone, a device (hereinafter referred to as A karaoke video device) is known.

An example of the above-mentioned conventional video and audio reproduction device will be described below with reference to the drawings. Figure 3 is a diagram showing changes in lyrics on the display screen of a conventional karaoke video device;
The figure is a block diagram of a conventional karaoke video device. In Figure 3, (a) and...) are both the display screens of a karaoke video device, (al shows the lyrics displayed before the song, and (b) shows the parts to be sung along with the accompaniment in color. It shows how it is expressed by changing it.In Figure 4, 4
1 is a video disc player that plays a video disc recording an accompaniment, a background image, and lyrics related to the accompaniment;
42 is a display device that displays the video signal played back by the video disc player 41; 42A is the background image displayed on the display device 42; 42B is the lyrics displayed on the display device 42; and 43 is the singer's voice as an audio signal. 44 is a mixer for mixing the audio signal from the video disc player 41 and the audio signal from the microphone 43; 45 is an amplifier for amplifying the audio signal output from the mixer 44; 46 is an amplifier for amplifying the audio signal output from the amplifier 45; A speaker that converts audio signals into sound and outputs it.

The operation of the audiovisual reproducing apparatus configured as described above will be described below.

First, the accompaniment played from the video disc player 41 passes through the mixer 44 and the amplifier 45 and is played from the speaker, and the video signal also played by the video disc player 41 is displayed on the display device before the song (see FIG. 3). al is displayed. When it is time to sing along with the accompaniment, the color of the lyrics corresponding to the accompaniment changes as shown in (b). The singer looks at the screen in (b) and sings according to the change in the color of the text. This audio signal is converted into an electrical signal by a microphone 43, mixed with accompaniment by a mixer 44, and outputted from a speaker 46 via an amplifier 45.

Problems to be Solved by the Invention However, in the color changing method described above, the current part to be sung is indicated by the change in color, so when a black and white display device is used, it is difficult to know which part to sing. had.

SUMMARY OF THE INVENTION In view of the above-mentioned problems, the present invention provides an audiovisual reproduction device that allows the user to clearly understand the part to be sung even when using a black and white display device.

Means for Solving the Problems In order to solve the above problems, the audiovisual reproduction device of the present invention displays the lyrics as a character string of a first size on the display screen of the display device that displays the video signal. , the character size of the portion of the character string synchronized with the audio signal is changed to a second size different from the first size at the time of synchronization and displayed.

Operation According to the present invention, the lyrics to be sung at the moment are represented by changing the size of the characters, and the part to be sung at the moment can be clearly understood even on a black and white display device.

Embodiment Hereinafter, a video and audio reproduction apparatus according to an embodiment of the present invention will be described with reference to the drawings. FIG. 1 is a diagram showing changes in lyrics display on the display screen of a karaoke video apparatus according to an embodiment of the present invention, and FIG. 2 is a diagram showing the configuration of the karaoke video apparatus according to an embodiment of the present invention.

In Figure 1, both (a) and the mountain) are the display screens of a karaoke video device, (a) shows the lyrics displayed before the song, and (b) shows the partial letters to be sung along with the accompaniment. It shows how the size is changed. In FIG. 2, 21 is a video disc player that plays back a video disc on which accompaniment, background images, and lyrics related to the accompaniment are recorded; 22 is a display device that displays the video signal played by the video disc player 21; 22A is a display device that displays the video signal played by the video disc player 21; The background image 22B displayed on the display device 22 is
23 is a microphone that converts the singer's voice into an audio signal; 24 is a mixer that mixes the audio signal from the video disc player 21 and the audio signal from the microphone 23; 25 is the output of the mixer 24; The amplifier 26 that amplifies the audio signal is a speaker that converts the audio signal output from the amplifier 25 into sound and outputs it.

The operation of the audiovisual reproducing apparatus configured as described above will be described below.

First, the accompaniment played from the video disk player 21 passes through the mixer 24 and the amplifier 25 and is played back from the speaker 26, and the video signal also played back by the video disk player 21 is displayed on the display device before the song. Fa
l is displayed. When the time comes to sing along with the accompaniment, the size of the letters corresponding to the accompaniment changes (like bl).The singer looks at the screen in (b) and sings the song according to the change in the size of the letters.This audio signal is converted into an electric signal by the microphone 23, mixed with accompaniment by the mixer 24, and outputted from the speaker 26 via the amplifier 25.

As described above, according to this embodiment, by providing a structure in which the part to be sung at present is indicated by changing the size of the characters, it is possible to clearly understand which part to sing even when using a black and white display device. I can do it.

In the above embodiments, a video and a disk player were used as the video/audio reproducing means, but any device may be used as the video/audio reproducing means as long as it can reproduce images and audio in real time. For example, a VTR can also be used.

Furthermore, in the above embodiment, in order to change the font size of the lyrics, a video signal whose font size changes according to the accompaniment is recorded on the recording medium in advance, but this is the only method for changing the font size. Instead, anything is fine as long as the size of the characters on the display screen changes to match the accompaniment. for example,
It is also possible to record the background image and lyrics characters separately and rewrite only the lyrics characters on the display device.

Also, in the above example, the size of the letters increases in accordance with the timing of the singing, but the size of the letters may change in any manner as long as the size of the letters changes in accordance with the accompaniment. . For example, it may be large at first and become smaller depending on the timing of the singing.

Effects of the Invention As described above, the present invention displays lyrics as a character string of a first size on a display screen of a display device that displays a video signal,
By providing a configuration in which the character size of the portion of the character string that is synchronized with the audio signal is changed to a second size different from the first size at the time of synchronization, the character string can be displayed even on a black and white screen. You can clearly understand where to sing.
