A display method includes: acquiring information representing a size of a projection area of a projector; acquiring an input image including a person; generating information representing a size of a face of the person included in the input image, based on the information representing the size of the projection area; correcting the input image in such a way that the size of the face of the person included in the input image becomes closer to life size in the projection area, based on the information representing the size of the face of the person; generating projection image data representing a projection image including the input image; and displaying the projection image in the projection area, based on the projection image data.
