A light-source device (300) including a light-emitting element (111R, 111G, and 111B) to emit light, a light-receiving system (LR), an acquisition unit (700a), a setting unit (700b), and an adjuster (700c). The light-receiving system (LR) receives the light emitted from the light emitting element (111R, 111G, and 111B). The acquisition unit (700a) acquires a wavelength of the light emitted from the light emitting element (111R, 111 G, and 111B). The setting unit (700b) sets a target value of an amount of the light received by the light-receiving system (111R, 111G, and 111B) based on the wavelength acquired by the acquisition unit (700a). The adjuster (700c) adjusts an amount of the light emitted from the light emitting element (111R, 111 G, and 111B) such that the amount of the light reaches the target value of the light that is set with the setting unit (700b).
