Beschreibung
Zusammenfassung:	A projector includes a housing, a projecting module, a first luminance sensor, and a control module. The projecting module installed inside the housing includes a light source for emitting light, a light valve for modulating the light into image light, and a lens for projecting the image light to a screen. The first luminance sensor installed inside the housing senses projective luminance of the image light projected on the screen. The control module installed inside the housing and coupled to the light source and the first luminance sensor adjusts luminance of light emitted from the light source according to a sensing result of the first luminance sensor.
