An electronic device includes a projection unit and a detection unit. The projection unit is configured to project light in a projection region on a projection surface. The detection unit is disposed away from the projection unit. The detection unit includes a photodetector and a notification light emitter. The photodetector is configured to detect reflected light of the light from the projection unit within a detection region. The notification light emitter is configured to emit to the projection surface notification light for setting a position of the projection region within the detection region of the photodetector.
