PROBLEM TO BE SOLVED: To securely image fluorescent images of arteries with high contrast without increasing dosage of a fluorescent agent, and reduce data quantity of the fluorescent images. SOLUTION: After the fluorescent agent is dosed, fluorescent images are imaged at a first imaging interval, and then it is switched to a second imaging interval that is longer than the first imaging interval to image fluorescent images. In imaging the fluorescent images of arteries, which start emission of fluorescence prior to veins, with higher blood flow speed, the fluorescent images are imaged at the first imaging interval that is relatively shorter. In imaging the fluorescent images of veins, which emit fluorescence after the arteries, with lower blood flow speed, the fluorescent images are imaged at the second imaging interval that is relatively longer.
