主权项 1. A light intensity control apparatus, comprising: an acquisition unit for acquiring a correction value of a light intensity of a first light source for observing a fundus and a correction value of a light intensity of a second light source for photographing the fundus, the correction values being changed in accordance with an instruction input by an inspector; a first control unit for controlling the light intensity of the first light source based on photometry information obtained by a photometry unit, the light intensity of the first light source obtained in the measurement by the photometry unit, and the changed correction value of the light intensity of the first light source, wherein the photometry unit measures reflected light from the fundus under illumination by the first light source; and a second control unit for controlling the light intensity of the second light source based on the photometry information obtained by the photometry unit, the light intensity of the first light source obtained in the measurement by the photometry unit, and the changed correction value of the light intensity of the second light source.
