AI Technical Summary

Problems solved by technology

At present, the camera lens generally includes five lenses, which can no longer meet the requirements of high resolution
For this reason, the resolution can be improved by increasing the number of lenses of the camera lens, however, this is not conducive to the miniaturization and weight reduction of the camera lens

Abstract

Provided are a camera lens assembly and a portable electronic device. The camera lens assembly includes first, second, third, fourth, fifth and sixth lenses from an object side to an image side. The first lens has a positive focal power and a convex object side surface. The second lens has a focal power and a symmetrically-transitional image side surface from concave to convex along a direction vertical to an optical axis, in which the image side surface is concave close to the optical axis and convex away from the optical axis. The third lens has a focal power and a convex object side surface. The fourth lens has a positive focal power and a convex image side surface. The fifth lens is of a focal power. The sixth lens has a negative focal power, a convex object side surface and a concave image side surface.

Description

technical field [0001] The invention relates to an imaging technology, in particular to a camera lens and a portable electronic device. Background technique [0002] The photosensitive element of the current imaging system includes a charge-coupled device (CCD) or a complementary metal-oxide semiconductor (complementary metal-oxide semiconductor, CMOS) image sensor. With the development of semiconductor process technology, the pixel size of the photosensitive element Smaller and smaller, the pixels of the imaging system are getting higher and higher, especially when the camera lens is applied to portable electronic devices such as wearable devices. Therefore, correspondingly, it is required that the imaging lens of the imaging lens has a higher resolution and a smaller size at the same time. At present, the camera lens generally includes five lenses, which cannot meet the requirements of high resolution. Therefore, the resolution can be improved by increasing the number of...
