Claim:
1. A light stimulation device comprising: an objective lens that radiates light emitted from a light source onto a specimen; a phase modulating section that is located at a position conjugate to a pupil of the objective lens and that is configured to modulate the phase of light to be made to enter the objective lens, based on a predetermined pupil modulation pattern; a light-amount adjusting section that adjusts an amount of light to be made to enter the phase modulating section; a spot specifying section that is used to specify a number of spots and/or a spot area and a spot position of light to be radiated onto the specimen by the objective lens; a pupil-modulation-pattern determining section that determines the predetermined pupil modulation pattern for the phase modulating section according to the number of spots and/or the spot area and the spot position specified by the spot specifying section; and a light-amount control section that controls the light-amount adjusting section such that, when the number of spots and/or the spot area specified by the spot specifying section is changed, the irradiation power for each spot before and after the change in the number of spots and/or the spot area becomes constant.
