Abstract

The invention discloses a camera shooting lens set and a camera shooting device of the camera shooting lens set. The camera shooting lens set sequentially comprises a prism, a first lens set body, a second lens set body and a third lens set body along an optical axis, the prism is a total reflection type lens, the first lens set body has the negative power and comprises at least one first lens set negative lens and at least one first lens set positive lens, the second lens set body has the positive power and comprises at least one second lens set positive lens and at least one second lens set negative lens, the third lens set body has the positive power and comprises at least one third lens set lens, and at least one optical surface of the at least one third lens set lens is an aspheric surface. The camera shooting lens set and the camera shooting device are good in aberration amendment and can be applied to small-size lens modules used for camera shooting.

Description

technical field [0001] The present invention relates to a camera lens group and its camera device, in particular to a camera lens group composed of a prism and three groups of lenses and its camera device, which is applied to a small lens module. Background technique [0002] On small electronic devices such as digital cameras (Digital Still Cameras), mobile phone cameras (mobile phone cameras), and web cameras (web cameras), periscope-type camera lens groups are often installed to take pictures of objects. The main trend of the development of camera lens sets is towards miniaturization and low cost, but at the same time, it is also hoped to achieve a camera lens set with good aberration correction capability, high resolution, and high imaging quality. [0003] In the known photographic lens group, it is most common to use an additional lens with a concave surface on the image side or a crescent lens with a convex surface on the object side in front of the prism for reflecti...
