Problems solved by technology

[0003] Traditionally, 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 (Smart Phone) and tablet computers (Tablet PC), the optical system is driven by the pixel With the rapid increase in imaging quality, known optical systems will not be able to meet higher-level photographic systems
Moreover, the resolution of the optical system traditionally configured in the vehicle camera device is relatively insufficient, but due

Abstract

The invention discloses an optical image capture system, an image capture device and an electronic device. The optical image capture system comprises a first lens, a second lens, a third lens, a fourth lens, a fifth lens, a sixth lens and a seventh lens in sequence from an object side to an image side. The first lens has negative refractive power, and the image-side surface is concave near the optical axis. The second lens has refractive power. The third lens has refractive power. The fourth lens has refractive power. The fifth lens has refractive power. The sixth lens has refractive power, the image-side surface is concave near the optical axis and contains at least one convex surface away from the optical axis, and both the object-side surface and the image-side surface are aspheric surfaces. The seventh lens has refractive power, the image-side surface is concave near the optical axis and contains at least one convex surface away from the optical axis, and both the object-side surface and the image-side surface are aspheric surfaces. When certain conditions are met, aberration is avoided. The invention further discloses an image capture device comprising the optical image capture system and an electronic device comprising the image capture device.

Description

technical field [0001] The invention relates to an optical image pickup system and an image pickup device, and in particular to a miniaturized optical image pickup system and an image pickup device applied to electronic devices. 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 the general optical system is nothing more than two types of photosensitive coupling device (Charge Coupled Device, CCD) or complementary metal oxide semiconductor element (Complementary Metal-Oxide Semiconductor Sensor, CMOS Sensor), and with the advancement of semiconductor technology, making The pixel size of the photosensitive element is shrinking, and the optical system is gradually developing into the high-pixel field, so the requirements for image quality are also increasing. [0003] Traditionally, optical systems mounted on electronic products ...
