Abstract:
1. A method for controlling a projector comprising: a temperature measuring step measuring a temperature of a projector; a light source part output determining step determining a light source part to be rated-output when the temperature measured in the temperature measuring step is less than or equal to a predetermined temperature and to be attenuated-output when the temperature measured in the temperature measuring step is greater than the predetermined temperature; and a light source part controlling step controlling the light source part according to the light source part output determined in the light source part output determining step, wherein the projector comprises at least one cooling fan, wherein, when the temperature measured in the temperature measuring step is less than or equal to the predetermined temperature, the at least one cooling fan is controlled at a rated-output, and wherein, when the light source part output determining step determines the light source part to be attenuated-output, the at least one cooling fan is controlled at an attenuated-output.
