Therefore, in a projector device including a light source device using a solid-state light source (AR) includes a temperature adjustment device (190) 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 (12) determines a luminance state of an image and a control unit (16) controls a heat state of the solid-state light source (AR) by controlling the temperature adjustment device (190) 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."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Projector device and control method","description":"An improvement in quality is achieved by improving a contrast ratio.
