Abstract
A fluorescence observation device includes a light source supplying excitation light, an interlaced imaging device, a field memory storing an image output from the imaging device, and a difference computing unit generating a difference image. The light source supplies the excitation light such that one of the first and second field image acquiring periods in the imaging device is a fluorescence image acquiring period, and the other is a background image acquiring period. The difference computing unit switches between a first mode of subtracting a background image of the memory from a fluorescence image output from the imaging device, and a second mode of subtracting a background image output from the imaging device from a fluorescence image of the memory, to apply the mode. Accordingly, it is possible to generate images in which fluorescence is extracted in real time.
