SOUND OUTPUT CONTROL METHOD AND DISPLAY SYSTEM
Document Type and Number:
Japanese Patent JP2020182049
Kind Code:
A
Abstract:
To provide a technology that can reflect information on the distance from a projector to a projection surface on control of the output state of sound from a speaker of the projector.SOLUTION: In a sound output control method executed by a display system 1000 having a first projector 11 that projects a first image 51 on a projection surface 3 through a first focus lens and outputs a sound based on a sound signal, and a second projector 12 that projects a second image 52 on the projection surface through a second focus lens and outputs a sound based on a sound signal, the second projector sets the position of the second focus lens on the basis of the state of focus of the second image on the projection surface, and transmits position information on the position of the second focus lens, and the first projector receives the position information, sets the position of the first focus lens on the basis of the state of focus of the first image on the projection surface, and controls output of the sound from the first projector on the basis of the position information and the position of the first focus lens.SELECTED DRAWING: Figure 1
