Abstract: 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.

Abstract: A projection direction change device includes a mirror that reflects light emitted from a projection lens unit of a projector, a mirror support part that rotatably supports the mirror around a first axis and a second axis, a first drive part that rotary drives the mirror around the first axis, and a second drive part that rotary drives the mirror around the second axis. An intersecting point of the first and second axes is positioned closer to the projection lens unit than a geometric barycenter of the mirror is.

Abstract: A projection-type image display apparatus includes a light source unit, an image generating unit that generates image light according to an input video signal, a light-guide optical system that guides the light from the light source unit to the image generating unit, a projection optical system that projects the image light generated by the image generating unit, and a controller. The controller has a display mode in which the image light is projected and an illumination mode in which the light from the light source unit is emitted as illumination light. The controller controls the optical system to focus illumination light from the projection optical system on a projection surface, in the display mode, and to focus illumination light from the projection optical system at a position different from the projection screen, in the illumination mode.
