Abstract
A light source control apparatus that includes a light quantity detection unit that respectively detects light quantities of three colors of light emitted from a light source part. A light quantity ratio calculation unit that then calculates light quantity ratios of reflection light detected by the light quantity detection unit. When the light quantity detection unit detects light quantities of respective reference of the lights emitted from the light source part, a determination unit determines whether or not the light quantity ratios calculated by the light quantity ratio calculation unit are within a predetermined range. Responsive to the determination of the determining unit, a light quantity ratio adjustment unit adjusts the light quantity ratios of the lights emitted from the light source part on the basis of the light quantity of green-colored reflection light emitted from the light source part.
