PROBLEM TO BE SOLVED: To provide an image projection device capable of determining the presence or absence of smoke generation around the device.SOLUTION: A projector 1 projecting an image onto a screen 310 includes a smoke detection part 151 to which a smoke sensor 61 is connected, as smoke detection means for detecting smoke and a temperature detection part 152 to which a temperature sensor 62 is connected, as temperature detection means for detecting temperature. Further, the projector 1 includes a determination program executed by a main body control part 110, as determination means for determining whether or not the smoke is generated due to an external factor around a device main body 100, on the basis of the detection results of the smoke detection part 151 and the temperature detection part 152. |
