The lens curvature variation apparatus according to an embodiment is a lens curvature variation apparatus for varying a curvature of a liquid lens which is variable based on an applied electrical signal. The lens curvature variation apparatus includes a lens driver to apply the electrical signal to the liquid lens, a sensor unit to sense the curvature of the liquid lens formed based on the electrical signal, and a controller to control the lens driver to form a target curvature of the liquid lens based on the sensed curvature, wherein the lens driver supplies the electrical signal to the liquid lens according to a switching operation of a switching element, and includes a detection element connected to one end of the switching element, wherein the sensor unit senses an electrical signal detected by the detection element. Thereby, the curvature of the lens can be sensed quickly and accurately."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Lens curvature variation apparatus","description":"The present invention relates to a lens curvature variation apparatus.
