A scanning laser ophthalmoscope comprises: a laser source that emits a laser beam an irradiation optical system that scans the laser beam over a fundus two-dimensionally a photoreceptor optical system that receives reflection from the fundus by using a photoreceptor element an image processor that obtains an image of the fundus based on an output signal from the photoreceptor element a monitor and a controller that causes the monitor to display the obtained fundus image, wherein the image processor comprises a subtractive processing circuit that performs time-subtractive processing on the output signal from the photoreceptor element in a state where the output signal is input as an analog signal, and forms the fundus image based on the signal subjected to the subtractive processing.
