Problems solved by technology

[0003] Traditionally, high-resolution miniaturized photographic lenses mounted on electronic devices mostly adopt a lens structure with a small number of lenses. The requirements for the pixel and imaging quality of the lens are improved, and the lens structure of the existing technology will not be able to meet the higher-level requirements
Furthermore, the imaging quality of traditional optical systems is difficult to be widely used in various environments, especially in electronic devices that require high imaging quality such as image recognition, lane departure warning systems, and unmanned vehicles.

Description

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