PROBLEM TO BE SOLVED: To prevent increase in cooling noise due to concentration of cooling down when a power source is turned off in a projector system composed by a plurality of projectors.SOLUTION: A projector 101 of a projector system includes: image projection means 10 for projecting light emitted from a light source 11 by modulation according to image information; temperature measuring means 27 for measuring temperature of interior of a housing of the projector 101; cooling means 25 for cooling at least the image projection means 10; and cooling control means 26 for executing cooling down controlling actions of the cooling means 25 in a set order until the temperature is brought down to termination temperature 211 or less which is set beforehand when a power source for the projector system is turned off. |
