Abstract
A projector includes an optical part including a light source section that outputs light, a light modulator that modulates the light outputted from the light source section based on an image signal, a projection optical section that projects the modulated light from the light modulator, a first fan that cools the optical part, and a fan controller that controls the first fan, and the fan controller operates the first fan intermittently when the light source section outputs light of luminance lower than luminance corresponding to normal image display.
Claims17
A projector comprising:
- an optical part including a light source section that outputs light;
- a light modulator that modulates the light outputted from the light source section based on an image signal;
- a projection optical section that projects the modulated light from the light modulator;
- a first fan that cools the optical part;
- and
- a fan controller that controls the first fan,
- wherein the fan controller operates the first fan intermittently when the light source section outputs light of luminance lower than luminance corresponding to normal image display.
A method for controlling a projector that projects an image and includes an optical part including alight source section that outputs light and a first fan that cools the optical part, the method comprising:
- causing the light source section to output light of luminance lower than luminance corresponding to normal display of the image;
- and
- operating the first fan intermittently.
