Is included.

  An operation panel 8 is connected to the input side of the operation control unit 7 and a remote control receiving unit 10 that receives a signal from the remote control transmitter 9 is connected. The operation control unit 7 receives music selection information issued from the operation panel 8 or the remote control transmitter 9 and outputs the received information to the central control unit 2. The central control unit 2 reads appropriate karaoke data from the hard disk device 6 based on this information.

  The synthesizer 11 receives music data sequentially transferred from the central control unit 2, and generates accompaniment music according to the music data. The mixing amplifier 12 mixes and amplifies the accompaniment music signal output from the synthesizer 11 and the voice signal of the singer output from the microphone 13 and outputs the mixed signal to the speaker 14.

  The central control unit 2 processes the lyric rendering data in synchronization with the accompaniment music generation processing by the synthesizer 11 and sequentially develops the lyric image in the video RAM 15 as a bitmap. Then, the video CD changer 16 is controlled to reproduce the image recorded on the video CD. Further, the video control unit 17 is controlled to superimpose the lyric image on the image image and output it to the monitor 18.

  The above is the basic configuration and function of the karaoke apparatus 1. In this embodiment, in addition to such configuration and function, the singing volume for detecting the singing volume as information related to the evaluation of the singer's voice. A singing volume detector 19 as detection means (evaluation information detection means) is connected to the output line of the microphone 13. The singing volume detector 19 receives the singer's voice signal output from the microphone 13 to detect the singing volume, and outputs the volume detection signal to the central control unit 2.

  The central control unit 2 performs processing so that the density, that is, the transmittance, of each character constituting the lyrics image changes according to the volume detection signal. Based on this processing result, the video RAM 15 develops a lyric image into a bitmap and sets a lyric character group displayed on the monitor 18, that is, a lyric telop, to a required transmittance. Therefore, the central control unit 2 and the video RAM 15 constitute a transmittance setting means for setting the transmittance to a required value.

When the performance reaches the part with the lyrics after the reproduction of the music is started, a lyrics telop is displayed on the monitor 18, and the singer enters the singing section where the singing is performed.

The lyrics telop transmittance setting control by the central control unit 2 and the video RAM 15 according to the change of the singing volume detected by the singing volume detector 19 in this singing section will be described with reference to FIGS. In this control, as shown in (a), (c), and (e) of FIG. 3, the change in the singing volume is appropriately divided into five levels of L ₄ , L ₃ , L ₂ , L ₁ , and L _0. At the same time, the transmission T is set in five stages of 100%, 90%, 60%, 30%, and 0% so as to be suitable for the singing guide corresponding to the grading of the singing volume. .

Singing starts a singer, the sound volume detection signal detected by the singing sound detector 19 is input to the central control unit 2, singing sound volume level L is compared to the level L ₄ (step S1). When singing sound volume of the singing person is sufficiently large L> L _4, the transmittance T of the lyrics telop is set to 100% (step S2), the lyrics telop on the monitor 18 is in a state of completely invisible. In comparison in step S1, the singing sound volume of the singing person When it is L _{<L 4} drops below the level _{L 4,} singing sound volume level L is compared to the level _{L 3} (step S3). If the singing volume level L is slightly lowered and L ₃ <L <L ₄ (FIG. 3 (a)), the transmission rate T of the lyrics telop is set to 90% (step S4) and is displayed on the monitor 18. Is displayed as a very thin lyric telop T ₉₀ with a transmittance T of 90% (FIG. 3B).

In comparison in step S3, the singing sound volume of the singing person When it is L _{<L 3} drops below the level _{L 3,} the singing sound volume level L is compared to the level _{L 2} (step S5). When the singing volume level L is further lowered and becomes L ₂ <L <L ₃ , the transmission rate T of the lyrics telop is set to 60% (step S 6), and the transmission rate T is 60 on the monitor 18. % lyrics telop _{T 60} is displayed. Singer singing proceeds of, come in singing confidence subside, singing sound volume level L is becomes the L <L _2, it is compared the singing sound volume level L level L ₁ (step S7). Then, when the singing volume level L is L ₁ <L <L ₂ (FIG. 3C), the transmission rate T of the lyrics telop is set to 30% (step S8), and is transmitted on the monitor 18. lyrics telop _{T 30} the rate T becomes darker to the extent legible even while singing of 30% is displayed (FIG. 3 (d)).

Singer singing becomes choppy, singing sound volume level L is equal to or L <L _1, the singing sound volume level L is compared to the level L ₀ (step S9). As a result of this comparison, if the singing volume level L is L ₀ <L <L ₁ (FIG. 3 (e)), the transmittance T of the lyrics telop is set to 0% (step S10), and on the monitor 18 The lyric telop T ₀ with a transparency T of 0% is displayed (FIG. 3 (f)). In this control, as in the lyrics telop T ₀ in FIG. 3 (f), the entire singing remaining lyrics telop is set to the same transmittance T according to the singing volume level L.

  In this way, when the singing volume level L decreases during singing, the transmittance T of the entire lyric telop remaining, that is, the display density is set to a low value step by step, and changes so that the lyric telop can be seen well. The singer is encouraged to continue singing, and the singing assistance of the singer is performed. On the other hand, when the singing volume level L is increased by the voice of a singer or the like with high singing ability, the transmission rate T of the lyrics telop is set to a high value and the lyrics telop becomes difficult to see, and the background image Appears clear and makes it easier to see messages that differ from the lyrics.

  As described above, in the lyrics telop display system of the karaoke apparatus according to the present embodiment, the change in the singing volume is divided into a plurality of levels, and a plurality of transmittance setting values corresponding to the singing volume are divided. While singing, while the singing volume level L of the singer changes during the singing, the display concentration of the lyrics telop changes step by step, giving the singer a stimulus to continue singing, Singing assistance can be performed.

  In the present embodiment, as described above, when the performance reaches a certain part of the lyrics after the reproduction of the music is started, the lyrics telop is displayed on the monitor 18. The operation initially hides the lyrics telop with a transmittance T of 100%. When the singing volume level L decreases during singing, the lyrics telop is displayed on the monitor 18 with the transmittance T according to the singing volume level L. It may be displayed. In addition, the change of the singing volume is divided into a plurality of levels and the setting value of the transmittance T is divided into a plurality of steps corresponding to the singing volume of the singing volume.
