Patent ID: 8303121

Claim:
A projector comprising: a speaker adapted to output a sound based on a sound signal; a light source; a light modulation device adapted to modulate light emitted from the light source in accordance with an image signal; a projection optical system adapted to project an image modulated by the light modulation device; a cover member disposed on a light path of the light emitted from the light source, and moving between a blocking position for blocking the light and a transmitting position for transmitting the light; a position detection section adapted to detect the position of the cover member; a microphone input terminal to which a microphone is connected; a microphone connection detection section adapted to detect whether or not the microphone is connected to the microphone input terminal; a loading section adapted to load a recording medium; a reproduction section adapted to reproduce a content recorded on the recording medium loaded to the loading section; a content identification section adapted to identify a type of the content the reproduction section reproduces; and a control section adapted to switch states of the projector, wherein the states of the projector include a sixth state in which the projector is powered ON, the microphone is unconnected according to a detection result of the microphone connection detection section, the type of the content the content identification section identifies is not an audio content, and the control section lights the light source at a second luminance lower than the first luminance in response to a cover closing operation.
