US Patent 11940597 Image capturing optical lens system, imaging apparatus and electronic device

An image capturing optical lens system includes four lens elements, which are, in order from an object side to an image side along an optical path, a first lens element, a second lens element, a third lens element and a fourth lens element. The first lens element has an object-side surface being convex in a paraxial region thereof. The third lens element with positive refractive power has an object-side surface being convex in a paraxial region thereof and an image-side surface being concave in a paraxial region thereof. The fourth lens element has negative refractive power.
