[0009] The voice information can include, for example, the approximate position of a microphone placed on the stage and the symbol of a musical instrument, but is not limited thereto. These pieces of information are shot on the stage directly by a camera or the like, or stored in a storage unit and displayed on a display.

The function of organizing voice information is a function of inputting a plurality of voice signals such as a voice taken from a microphone or an existing voice to an arithmetic unit of a display unit and synthesizing them based on an operation signal of an operator. Etc., but is not limited to this.

The output device may be any device as long as it can output the sound organized by the composition function, and for example, an output device including an amplifier and a speaker is applicable. The type of speaker is not particularly limited,
Any ordinary loudspeaker type microphone type or the like may be used. The number of speakers may be set in correspondence with the number of musical instruments.

The display may be a CRT display, a liquid crystal display, a plasma display, or the like, and the optical member may be a known one such as a concave-convex lens or a mirror. In addition, the combiner may be anything as long as it transmits the light from the front stage to the rear (toward the viewer's seat) and redirects the image display light projected from the display device to the direction that can be visually recognized by the viewer. .

[0013]

According to the present invention, a plurality of audio signals such as a voice picked up from a microphone or an existing voice is input to the arithmetic unit of the display unit, and these are combined based on the operation signal of the operator to obtain a voice. To enable emphasis and composition.
