A projector in an installation information acquisition method is installed in a real space, has a changeable projection direction, and projects a projection image based on a virtual image. The virtual image is an image in a case where an image arranged at a display position in a virtual space is viewed from a virtual installation position. The method includes first acquisition processing for acquiring positional information of three or more first adjustment points in the virtual space, projection processing for projecting, by the projector, an index image onto the real space, second acquisition processing for acquiring angle information of the projection direction with respect to a reference direction in a state where the index image matches three or more second adjustment points respectively corresponding to the three or more first adjustment points, and third acquisition processing for acquiring installation information based on the positional information and the angle information.

A content generation method generates image content to be projected at a projection position in a real space by a projector. In a first acquisition process, space information regarding a virtual space corresponding to the real space is acquired. In a second acquisition process, display position information regarding a display position corresponding to the projection position in the virtual space is acquired. In a third acquisition process, reference position information regarding a reference position in the virtual space is acquired. In a generation process, an image including an object viewed from the reference position when the object is displayed at the display position in the virtual space is generated as the image content, based on the space information, the reference position information, and the display position information.
