Abstract

The invention discloses an optical lens set for image taking, an image taking device and an electronic device. The optical lens set for image taking orderly comprises a first lens, a second lens, a third lens, a fourth lens and a fifth lens from an object side to an image side. The first lens has negative refracting power, and the image side surface is a concave surface. The image side surface of the third lens is a convex surface. The fourth lens has positive refracting power. The object side surface of the fifth lens is a concave surface, and the optical lens set for image taking comprises five lenses. When certain conditions are satisfied, the configuration of the refractive power between the lenses can be balanced, and the ability of aberration correction can be effectively improved. The invention also discloses the image taking device with the above optical lens set for image taking and the electronic device with the image taking device.

Description

technical field [0001] The present invention relates to an optical lens group for image capturing and an image capturing device, and in particular to an optical lens group for image capturing with a wide viewing angle and an image capturing device applied to electronic devices. Background technique [0002] In recent years, with the gradual popularization of lens types and uses, many products (such as home appliances, game consoles, monitors, automobiles, electronic products and mobile devices, etc.) are equipped with lenses, which are suitable for image assistance, image recognition, Motion detection and other functions. Some devices often have to operate in an environment with a low light source or low light intensity (such as an infrared device that detects the position of the human body). Correspondingly, the optical lens of the matching device must also have sufficient light input. It is known that most of the optical lenses used in products currently on the market can...
