The projection unit has a projection lens fixed on a side surface of the electronic device. The ambient light sensor is fixed on the side surface of the electronic device. The processing unit is configured to: control an average brightness of a screen projected by the projection unit as a first brightness value, and control the ambient light sensor to sense to derive a first measured brightness value; control an average brightness of the screen projected by the projection unit as a second brightness value, and control the ambient light sensor to sense to derive a second measured brightness value; calculate an ambient contrast ratio according to the first measured brightness value and the second measured brightness value; and adjust a projecting setting of the projection unit according to the ambient contrast ratio."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Electronic device and method for adjusting setting for projecting screen by re-calculating ambient contrast ratio according to variation of ambient light","description":"An electronic device including a projection unit, an ambient light sensor and a processing unit is provided.
