More Information
Summary:An image capturing apparatus includes a cover plate, a first lens element, a second lens element, a third lens element, and a sensor arranged sequentially from an object side to an image side along an optical axis. The number of lens elements in the image capturing apparatus is only three. The image capturing apparatus satisfies: f/imgH < 0.45, and 2 < (OTL-d)/imgH < 9, wherein f is an effective focal length of the image capturing apparatus, imgH is a maximum image height of the image capturing apparatus, OTL is a distance from an object to an image plane on the optical axis, and d is a thickness of the cover plate.
