The electronic device includes a projector device that projects an image formed by an optical image formation element, an imaging device that captures an image of an object to be photographed so that an imaging range includes the range of projection by the projector device and outputs an image signal, an image change detection unit that detects change of the image signal after having excluded the projection range from the range photographed by the imaging device, and a command unit that issues a command related to operation of the projector device according to the region within the imaging range in which change has been detected by the image change detection unit. |
