Camera module with high pixel, large target area, large aperture and ultra-wide angle

Abstract

The embodiment of the invention discloses a camera module with high pixel, large target area, large aperture and an ultra-wide angle. A first lens, a second lens, a third lens, a fourth lens, a fifthlens and a sixth lens are sequentially arranged along an optical axis from an object plane to an image plane, wherein the focal power of the first lens is negative; the focal power of the second lensis negative; the focal power of the third lens is negative; the focal power of the fourth lens is positive; the focal power of the fifth lens is positive; the focal power of the sixth lens is negative; in addition, optical total length TTL of an optical system meets the condition that the TTL is greater than or equal to 20mm and smaller than or equal to 28mm. The embodiment of the invention mainlycomprises six lenses; with low quantity of the lenses, the camera module is simple in structure and relatively-low in cost; by different lens combination and reasonable distribution of focal power, the chromatic aberration and temperature effect of the system can be effectively compensated; the camera module has good optical properties of the large target area, the large aperture, good resolvingpower, small distortion, excellent temperature performance and the like.

Description

Technical field: [0001] The invention relates to a camera module, in particular to a super wide-angle camera module with high pixels, large target surface and large aperture. Background technique: [0002] At present, all-glass camera modules used in electronic products generally have defects such as low resolution, serious purple fringing in large aperture optical systems, and poor temperature effects. At the same time, high-pixel and large-target camera modules usually adopt a structure above 8G, which has problems such as high cost, small aperture, and low light transmission. Invention content: [0003] In order to overcome the common problems of low resolution, serious purple fringing, and poor temperature effect in existing camera modules, an embodiment of the present invention provides a super wide-angle camera module with high pixels, large target surface and large aperture. [0004] High-pixel, large-target, large-aperture, ultra-wide-angle camera module, along th...
