Title:
OPTICAL IMAGING SYSTEM, CAMERA MODULE AND ELECTRONIC DEVICE
Document Type and Number:
WIPO Patent Application WO/2023/125551
Kind Code:
A1
Abstract:
Provided in the present application are an optical imaging system, a camera module and an electronic device. The optical imaging system is used in conjunction with an ejection mechanism. The optical imaging system comprises a first lens to an Nth lens, which are sequentially arranged from an object side to an image side along an optical axis, wherein the first lens to the Nth lens all have focal power, where 7 ≤ N ≤ 10; the first lens to the Nth lens are sequentially divided into a first group and a second group from the object side to the image side; the first group has a positive focal power; and the distance between the second group and an image plane in an optical axis direction is fixed. The ejection mechanism is used for driving the first group to eject from a non-working position to a working position in the optical axis direction, wherein the working position and the non-working position are sequentially arranged from the object side to the image side direction. The optical imaging system satisfies the following relational expression: 0 < ImgH/TTL ≤ 1. The first group is separately ejected, and a relationship between the total optical length and the maximum image height is rationally configured, so as to realize miniaturization and automatic focusing, and improve the resolving power of the optical imaging system.
