  • a projector that includes a projection optical system and projects a projection image;

    an image sensor that captures a photography image; and

    an illumination unit that includes an illumination optical system which is different from the projection optical system and emits an illumination light by light from a light source when the image sensor captures the photography image, wherein;

    the illumination unit does not emit the illumination light when the projector projects the projection image; and

    further comprising a processor that controls the projector and the illumination unit, wherein;

    the processor controls the projector differently between a case in which the projection image is projected onto a placing surface on which the electronic device is placed and a case in which the projection image is projected onto a surface other than the placing surface.
