The method includes projecting screen data by enabling an auto-focusing operation of the projector; capturing the projected screen data through the camera, and detecting a change of a value of the captured screen through a sensor; and when the change of the value is greater than a preset threshold value, temporarily stopping the auto-focusing operation of the projector and projecting the screen data."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Method and apparatus for controlling focus of projector of portable terminal","description":"Disclosed are a method and an apparatus for controlling the focus of a projector of a portable terminal when the projector is operated.
