PROBLEM TO BE SOLVED: To enhance the detection accuracy of a light spot of an irradiation device.SOLUTION: An image projection device includes a drive control section for generating the light color of image data by performing such a control as transmitting the light, on an hourly basis, to a plurality of color regions determined by the light color of image data, and an image capturing control section for receiving a synchronization signal, specified as a timing not projecting light out of the plurality of color regions from the drive control section, for the light color of a light spot of an irradiation device thus set, controlling exposure and image capturing of an imaging section according to a timing specified by the synchronization signal, and capturing the image of the image data thus projected. |
