See full text

A light source control device and a light source control method each capable of preventing the scroll noise from occurring without being affected by the characteristics of a light modulation device, and a projector equipped with the light source control device are provided. The light source device includes a duty determination section adapted to determine a duty ratio, and a drive control section adapted to perform drive control of a plurality of solid-state light sources by generating a PWM signal having the duty ratio determined by the duty ratio determination section, and adapted to make a phase with which at least one of the solid-state light sources is driven different from a phase with which another of the solid-state light sources is driven.
