Abstract

The present invention provides a camera lens group, an image capture and an electronic device. The camera lens group comprises a first lens, a second lens, a third lens, a fourth lens, a fifth lens and a sixth lens which have refraction power and arranged in order from an object side to an image side. The first lens has the positive refraction power, and the surface of the object side of the first lens close to an optical axis is a convex surface. The second lens has a negative refraction power. The third lens has the positive refraction power, and the two surfaces of which are both aspheric. The fourth lens has the refraction power, and the two surfaces of which are both aspheric. The fourth lens has the negative refraction power, and the two surfaces of which are both aspheric. The sixth lens has the positive refraction power, and the surface of the object side of the first lens close to an optical axis is a concave surface. The surface of the object side close to the optical axis is a convex surface, and two surfaces are both aspheric. There is an air interval between two adjacent lenses on the optical axis of the first lens, the second lens, the third lens, the fourth lens, the fifth lens and the sixth lens. The present invention further discloses an image capture device with an optical camera lens group and an electronic device with the image capture device.

Description

technical field [0001] The invention relates to a camera lens group, an image pickup device and an electronic device, in particular to a camera lens group 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 current market...
