Before a fluorescent labeling agent is administered on an observation area, the observation area is irradiated with an excitation light for fluorescence quenching. An image taking unit captures two fluorescence images at a predetermined time interval during the irradiation with the excitation light. The first fluorescence image is written to a first frame memory, and a second fluorescence image is written to a second frame memory. An image processing circuit reads out the two fluorescence images, and calculates a difference in light intensity between the two fluorescence images. A judgment circuit judges whether or not fluorescence from a fluorescent dye that has already existed in the observation area is quenched based on the difference in light intensity.
