Problems solved by technology

Although five-element optical systems have been developed, traditional five-element optical systems are difficult to have the characteristics of wide viewing angle and miniaturization at the same time, and often have the problem that the shape of a single lens changes too much due to too strong refractive power.

Abstract

The invention discloses an optical camera system, an image pickup device and an electronic device. The optical camera system sequentially comprises a first lens, a second lens, a third lens, a fourth lens and a fifth lens with refraction power from an object side to an image side. The first lens has refraction power, and the object-side surface is convex near the optical axis. The second lens has positive refraction power, the image-side surface is convex near the optical axis, and the second lens contains at least one aspheric surface. The third lens has negative refraction power, the object-side surface is concave near the optical axis, and the third lens contains at least one aspheric surface. The fourth lens has positive refraction power, the object-side surface is concave near the optical axis, the image-side surface is convex near the optical axis, and the fourth lens contains at least one aspheric surface. The fifth lens has negative refraction power, the image-side surface is concave near the optical axis, the image-side surface has at least one convex surface away from the optical axis, and the fifth lens has two aspheric surfaces. The invention further discloses an image pickup device comprising the optical camera system, and an electronic device comprising the image pickup device.

Description

technical field [0001] The invention relates to an optical camera system, an image pickup device and an electronic device, in particular to an optical camera system and an image pickup device suitable for the electronic device. Background technique [0002] In recent years, with the vigorous development of miniaturized photographic lenses, the demand for miniature imaging modules has been increasing day by day, and the photosensitive elements of general photographic lenses are nothing more than charge coupled devices (CCD) or complementary metal oxide semiconductor elements. (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 photographic lenses with good imaging quality have become the mainstream in the curr...
