Low-sensitivity and high-quality fidelity camera assembly

Abstract

The invention discloses a low-sensitivity and high-quality fidelity camera assembly. The camera assembly sequentially comprises a first lens having positive focal power, a crescent-shaped second lens having positive focal power and bending towards an object space, a third lens having negative focal power, an imaging face, an optical filter and a diaphragm in the direction from the object side to the image side along an optical axis of the camera assembly, wherein the first lens is provided with a convex face towards the object side and a convex face towards the image side; the second lens is provided with a concave face towards the object side; the optical filter is located between the third lens and the imaging face; the diaphragm is located between the object space and the first lens. In addition, the camera assembly meets the following conditions that (1) 0.7<F / F1<1.2, -0.7<F3 / F2<-1.5; (2) 0.6<F12 / Y<1.4; (3) 4<T12 / T23<11; (4) 0.2<BL / TTL<0.6. The camera assembly is designed aiming at a current high-pixel photographing digital product, has the characteristics of being low in sensitivity and high in fidelity, and can guarantee high imaging quality on the premise of meeting miniaturization.

Description

Technical field: [0001] The invention relates to the technical field of camera products, in particular to a low-sensitivity high-fidelity camera assembly. Background technique: [0002] With the development of science and technology, the functions of various digital products are increasing day by day, for example, camera components are integrated in many digital products. However, with the continuous updating of products, consumers' requirements for photographic quality in digital products are also advancing with the times. Looking back on the more than ten years since the birth of the camera phone in 2000, the camera function has gradually penetrated into almost all models of mobile phones and gradually matured. From the perspective of pixels alone, the lens has changed from the original hundreds of thousands of pixels to the current mainstream megapixels. Pixel lens, the image quality is gradually improving; on the other hand, driven by the continuous thinning and thinnin...

Problems solved by technology

Although the application for the invention uses a three-piece camera lens group, there are deficiencies in the selection of lens specifications, resulting in the inability to effectively reduce the optical sensitivity, and there is still room for further reduction in the overall length of the lens group
