Problems solved by technology

[0003] Traditional optical systems mounted on electronic products mostly use four-element or five-element lens structures. However, due to the prevalence of high-standard mobile devices such as smart phones (SmartPhone) and tablet computers (Tablet PC), the optical system is driven by pixels and imaging. With the rapid increase in quality, known optical systems will not be able to meet higher-level photographic systems
[0004] Although the six-element optical system has been further developed at present, the refractive power of the overall optical system cannot be effectively moved toward the object side due to the configuration of the refractive power of the first lens, which leads to the fact that the optical system cannot be shortened at the same time under the configuration of a small viewing angle. back focus, and prone to stray light
Furthermore, the surface shape of the fifth lens cannot reduce the generation of stray light, resulting in poor overall imaging quality

Description

technical field [0001] The invention relates to an optical camera lens group and an image pickup device, and in particular to a miniaturized optical camera lens group and an image pickup device applied to an electronic device. Background technique [0002] In recent years, with the rise of electronic products with photographic functions, the demand for optical systems has increased day by day. The photosensitive element of a general optical system is nothing more than a photosensitive coupling device (Charge Coupled Device, CCD) or a complementary metal oxide semiconductor element (Complementary Metal-Oxide Semiconductor Sensor, CMOS Sensor), and with the advancement of semiconductor technology, the pixel size of the photosensitive element Zooming out, the optical system is gradually developing towards the high-pixel field, so the requirements for imaging quality are also increasing. [0003] Traditional optical systems mounted on electronic products mostly use four-element...
