Description

  The present invention changes the display size of the lyrics telop displayed on the display device according to the distance from the singer of each singing part to the display device when playing karaoke music composed of a plurality of singing parts. The present invention relates to a possible lyrics telop display size control system.

  When enjoying karaoke at snacks, bars, etc., it is common for each user to sing at a seated position, except in stores where stages are installed. In a normal case, a large display device is installed in the store, and the user sings while watching the lyrics telop displayed together with the background video on the display device. However, the distance between the seating position of each user and the display device is not necessarily the same, and a singer sitting at a position close to the display device can see the lyrics telop at a close while sitting at a position far from the display device. Singers may have difficulty viewing lyrics telop.

  Conventionally, a technique related to a karaoke device that can change the size of a lyrics telop displayed on a display device has been disclosed (see Patent Document 1). The technique described in Patent Document 1 determines that the display size of the lyrics telop is too small for the singer when the sound pressure level of the singing voice input from the microphone is smaller than the reference singing voice data. This is a technique for controlling the display size to be increased.

JP-A-5-11785

  By the way, when singing karaoke music composed of multiple singing parts such as duet music, if the seating positions of the singers of each part are close to each other, the distance from each singer to the display device is almost the same. The visual status of the lyrics telop is almost the same. However, when the singers of each part are seated apart, the distance from each singer to the display device may be greatly different. In this case, the visual state of the lyrics telop is different for each singer. End up. That is, for a singer who is seated relatively close to the display device, even if the display size of the lyrics telop is appropriate, the singer who is seated relatively far from the display device For this reason, the display size of the lyrics telop is too small, and it may be difficult to see the lyrics telop. On the other hand, when the display size of the lyrics telop is too large, it makes it difficult to see the background image displayed in order to increase the atmosphere of karaoke, and the original enjoyment of karaoke is impaired.

  The present invention has been proposed in view of the above-described circumstances, and when playing karaoke music composed of a plurality of singing parts, even if the distance between the singer of each singing part and the display device is different. Another object of the present invention is to provide a lyrics telop display size control system capable of displaying lyrics telops with a display size suitable for the distance between the singer of each singing part and the display device.

  The lyrics telop display size control system of the present invention has the following features in order to achieve the above-described object. That is, the lyrics telop display size control system of the present invention displays on the display device according to the distance from the singer of each singing part to the display device when playing karaoke music composed of a plurality of singing parts. The lyric telop display size can be changed, and includes a singer distance calculating means and a lyric telop display control means.

  The singer distance calculating means is a means for calculating each distance from the singer associated with each singing part to the display device. The lyrics telop display control means controls the display of the lyrics telop displayed on the display device based on the correlation table or the correlation function in which the distance from the singer to the display device and the display size of the lyrics telop are associated with each other. In the singing part that sings in the singing part, the lyrics telop is displayed in a display size corresponding to the distance between the singer and the display device, and in the singing part that sings in a plurality of singing parts, each singer and the display device This is a means for displaying the lyrics telop with a display size corresponding to the average value of the distance.

  In the lyrics telop display size control system having such a configuration, when performing a karaoke piece composed of a plurality of singing parts such as a duet piece, each singing part (for example, by the function of the singer distance calculating means) The distance from the singer who sings the male voice part or female voice part) to the display device is calculated. Moreover, in this invention, it has the correlation table or correlation function which matched the distance from a singer to a display apparatus, and the display size of a lyric telop. Then, by the function of the lyrics telop display control means, the display size of the lyrics telop is changed for each singing part in correspondence with the distance from the singer of each singing part to the display device. That is, in the singing part that sings in a single singing part, the lyrics telop is displayed with a display size corresponding to the distance from the singer who sings the singing part to the display device, and in the singing part that sings in a plurality of singing parts, The lyrics telop is displayed in a display size corresponding to the average value of the distance from each singer to the display device. At this time, if the distance from the singer to the display device is relatively short, the display size is relatively small, and if the distance from the singer to the display device is relatively long, the display size is relatively Just make it bigger.

  Also, each distance from the singer associated with each singing part calculated by the singer distance calculating means to the display device is displayed from the microphone holon used by the singer associated with each singing part. It can be configured as each distance to the device.

  In the lyrics telop display size control system having such a configuration, a microphone to be used for each singing part is specified in advance, and the distance from each microphone to the display device is calculated by the function of the singer distance calculating means. For example, a radio wave transmitter is built in a microphone, and a radio wave receiver is installed in the vicinity of the display device. The distance from each microphone to the display device can be calculated based on the reception intensity of the radio wave input to the radio wave receiver. Further, the distance from each microphone to the display device may be calculated based on the reception intensity of the carrier wave on which the audio signal transmitted from the microphone is superimposed. That is, if the reception intensity of the radio wave transmitted from the microphone is relatively strong, the distance from the microphone to the display device is relatively short. Conversely, if the reception intensity of the radio wave is relatively weak, the distance from the microphone to the display device is The distance is relatively far.

  In the lyrics telop display size control system of the present invention, when the distance from the singer to the display device is relatively short, the display size is relatively small, and when the distance from the singer to the display device is relatively long The display size of the lyrics telop can be changed according to the distance from the singer to the display device, such as relatively increasing the display size. Furthermore, when a plurality of singers sing a duet composed of a plurality of singing parts, especially when singing in a choral part, even if the distance from each singer to the display device is different, it is appropriate. Lyric telop can be displayed in the display size. Therefore, no matter where the singers such as duet songs composed of multiple singing parts are located, displaying the lyrics telop in the optimal display size for each singer makes it easy to see the lyrics telop, Can be performed suitably.

  In general, since singing is performed with a microphone during singing, the distance from the singer to the display device can be easily and accurately grasped by detecting the distance from the microphone to the display device. Furthermore, since the distance from the singer who sings each singing part to the display device can be calculated just by incorporating the device for measuring the singer distance into the existing microphone, the device configuration is not complicated, The manufacturing cost of the device can be reduced.
