Abstract

The invention discloses an optical image system, an image capturing device and an electronic device. The optical image system includes, in order from an object side to an image side, a first lens element, a second lens element, a third lens element, a fourth lens element, a fifth lens element and a sixth lens element. The first lens element with positive refractive power has an object-side surface being convex in a paraxial region thereof. The second lens element has an image-side surface being concave in a paraxial region thereof. The third lens element has negative refractive power. The fifth lens element with negative refractive power has an object-side surface and an image-side surface being both aspheric. The sixth lens element has an object-side surface and an image-side surface being both aspheric.

Description

technical field [0001] The present invention relates to an optical image system and an image capturing device, and in particular to a miniaturized optical image system and an image capturing device applied to an electronic device. Background technique [0002] As the application of camera modules becomes more and more extensive, it will be a major trend of future technological development to install camera modules in various smart electronic products, vehicle devices, identification systems, entertainment devices, sports devices and home intelligent assistance systems. In order to have a wider application field, smart devices equipped with one, two, or even more than three lenses have gradually become the mainstream of the market, and in response to different application requirements, lens systems with different characteristics have been developed. [0003] Moreover, in recent years, electronic products have demanded thinner and lighter, so traditional photographic lenses, e...
