Problems solved by technology

[0003] Traditional high-resolution miniaturized photographic lenses mounted on portable electronic products mostly adopt a five-element lens structure. The popularity of the miniaturized camera lens has led to an increase in pixel and imaging quality requirements, and the existing five-element lens group will not be able to meet higher-level requirements
[0004] At present, although there is further development of the general traditional six-piece optical system, the configuration of the refractive power of the lens is not appropriate. The excessively strong refractive power and the excessive change of the surface shape make the system more sensitive and stabilize the imaging performance. restricted

Abstract

An image capturing lens assembly 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 and third lens elements have refractive power. The fourth lens element with refractive power has an object-side surface being concave in a paraxial region thereof. The fifth lens element with refractive power has an object-side surface being convex in a paraxial region thereof and an image-side surface being concave in a paraxial region thereof. The sixth lens element with refractive power has an image-side surface being concave in a paraxial region thereof. The image capturing lens assembly has six lens elements with refractive power.

Description

technical field [0001] The invention relates to a camera lens group, an image pickup device and a portable device, in particular to a miniaturized camera lens group and an image pickup device suitable for a portable device. Background technique [0002] In recent years, with the vigorous development of miniaturized photographic lenses, the demand for miniature imaging modules has increased day by day, and the photosensitive elements of general photographic lenses are nothing more than charge coupled devices (Charge Coupled Device, CCD) or complementary metal oxide semiconductors. There are two types of components (Complementary Metal-Oxide Semiconductor Sensor, CMOS Sensor), and with the improvement of semiconductor process technology, the pixel size of the photosensitive element has been reduced, and today's electronic products are developing with good functions and thin, light and small appearance. Therefore, miniaturized photographic lenses with good imaging quality have ...
