1. A content generation method for generating image content to be projected at a projection position in a real space by a projector, the content generation method comprising:
a first acquisition process that acquires space information regarding a virtual space corresponding to the real space;
a second acquisition process that acquires display position information regarding a display position corresponding to the projection position in the virtual space;
a third acquisition process that acquires reference position information regarding a reference position in the virtual space;
a display process that displays an object on a virtual projection surface including the display position in the virtual space based on the space information, the reference position information, and the display position information;
an arrangement process that arranges a virtual camera at the reference position in the virtual space, the virtual camera having an angle of view that is same as an angle of view of the projector; and
a generation process that captures, by the virtual camera, an image including the object viewed from the reference position, and generates the captured image as the image content.
