Abstract
An improvement in quality is achieved by improving a contrast ratio. Therefore, in a projector device including a light source device using a solid-state light source (AR) includes a temperature adjustment device () capable of setting a state in which a temperature of at least the solid-state light source is caused to increase. Then, a determination unit () determines a luminance state of an image and a control unit () controls a heat state of the solid-state light source (AR) by controlling the temperature adjustment device () on the basis of a determination result. In particular, by increasing the temperature of the solid-state light source (AR) in accordance with an image, light emission efficiency is lowered to decrease luminance.
