Abstract: Provided is an imaging system capable of acquiring images that favorably show the situation in a mobile object seen through a window regardless of the height of a passing mobile object. The imaging device 3 images a mobile object. The first lighting device 1 irradiates the mobile object with light. The second lighting device 2 is installed at a position higher than the first lighting device 1 and irradiates the mobile object with light. The control unit 4 causes the first lighting device 1 and the second lighting device 2 to emit light in respective patterns while the imaging device 3 is imaging a mobile object over a plurality of frames. The selector 5 selects images acquired by imaging a mobile object irradiated with light in a preset manner depending on the height of the mobile object from among images for a plurality of frames.
