Abstract: An electronic device includes a photodetector, a notification light emitter, and a determination component. The photodetector detects reflected light of light from a projection device within a detection region, the projection device projecting the light in a projection region on a projection surface. The notification light emitter emits on the projection surface two notification lines of visible wavelength that approach each other towards the photodetector. The determination component determines that the projection region is at least partially located outside the detection region based on a detection result of the photodetector. The determination component further determines that an edge of the projection region that is located closest to the photodetector is substantially parallel to a line segment that connects ends of the two notification lines.

Abstract: A projector is provided which includes: a Peltier device having a first surface in contact with an optical component (heat generating component) and a second surface in contact with a heat sink (heat dissipating component); and a Peltier device driving unit as a controller that generates a temperature difference between the two surfaces of the Peltier device by applying a cyclically changing voltage to the Peltier device. The Peltier device driving unit applies to the Peltier device a first voltage in a first of two time periods of a cycle and applies a lower second voltage in the second time period, the first voltage being for transferring heat from the optical component to the heat sink to reduce the temperature of the first surface below that of the second surface, and the second voltage being for preventing the transfer of heat from the second surface to the first surface.
