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-piece optical system has been further developed at present, due to the configuration of the refractive power of the first lens, the light gathering ability of the overall optical system cannot be concentrated on the object side, resulting in the overall length of the optical system being too long and the overall volume being too large

Abstract

The invention discloses a photographic optical lens set, an image capture device and an electronic device. The photographic optical lens set comprises a first lens, a second lens, a third lens, a fourth lens, a fifth lens and a sixth lens in sequence from an object side to an image side. The first lens has positive refractive power, and the object side surface thereof near an optic axis is a convex surface. The second lens has refractive power. The third lens has refractive power, and the object side surface and the image side surface thereof are aspheric surfaces. The fourth lens has refractive power, and the object side surface and the image side surface thereof are aspheric surfaces. The fifth lens has refractive power, and the object side surface and the image side surface thereof are aspheric surfaces. The sixth lens has refractive power, and the object side surface and the image side surface thereof are aspheric surfaces. The invention further discloses an image capture device with the photographic optical lens set and an electronic device with the image capture device. When a specific condition is satisfied, the spatial configuration of the lens can be controlled, and the telephoto capability can be improved.

Description

technical field [0001] The invention relates to a photographic optical lens set and an image-taking device, and in particular to a miniaturized photographic optical lens set and an image-capturing 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 fo...
