Patent ID: 7592574

Claim:
A light source control apparatus comprising: a light quantity detection unit that detects light quantities according to a result of reading out reflection light of three primary colors of light emitted onto a reference white board from a light source part, the three primary colors of light corresponding to red, green, and blue; a light quantity ratio calculation unit that calculates light quantity ratios of the reflection light detected by the light quantity detection unit; a determination unit that, when the light quantity detection unit detects light quantities of the three primary colors of light emitted onto the reference white board from the light source part, determines whether or not the light quantity ratios calculated by the light quantity ratio calculation unit are within a predetermined range; and a light quantity ratio adjustment unit that adjusts the light quantity ratios of the three primary colors of light emitted onto the reference white board from the light source part on the basis of a light quantity of green-colored reflection light emitted onto the reference white board from the light source part and corresponding to a determination by the determination unit.
