PROBLEM TO BE SOLVED: To provide a technique for ensuring the performance of a video output device by preventing occurrence of dew condensation at a position of an optical component, or the like.SOLUTION: A video output device has a housing 150 including a light source device 101, an optical component 102, and an optical window 103, a control section 110 for controlling output of video, a first cooling element 121 installed in a first region in the housing 150 including the light source device 101, and a second cooling element 122 installed at a position separated from a second region of dew condensation prevention object including the optical component 102 and optical window 103. By cooling the first region with the first cooling element 121, and cooling the third region with the second cooling element 122, the second region becomes a relatively high temperature part in the housing 150, and the third region becomes a relatively low temperature part, thus retarding dew condensation in the second region. |
