Problems solved by technology

However, the improvement of the pixels of the camera lens still cannot meet people's increasing requirements for the imaging quality of the camera lens, which will inevitably require more lens elements to improve the imaging quality of the camera lens
However, the increase in lens elements will lead to an increase in the height of the camera lens, which cannot meet the needs of thinner and lighter personal electronic products

Abstract

The invention provides a camera lens and electronic equipment. The camera lens comprises first to fifth lenses arranged sequentially along a same optical axis from an object side to an image side, wherein the camera lens is in accordance with following relational expressions:1.3<TTL / Imgh<1.5; 0.7<|f / f2|<0.8; 0.4<|f / f3|+|f / f4|<0.75; 3.2<R10 / f<30; -0.91< / =(R9+R10) / (R9-R10)<0. Therefore, by reasonable setup of parameters of each lens, the total length of the camera lens can be reduced on the premise that high pixel is realized, and the requirement on miniaturization of the camera lens and the electronic equipment is met.

Description

technical field [0001] The present invention relates to the technical field of camera lenses, and more specifically, to a camera lens and electronic equipment. Background technique [0002] With the development of semiconductor technology, the pixel area of ​​the photosensitive element is getting smaller and smaller, and the pixel of the camera lens is getting higher and higher. However, the improvement of the pixels of the camera lens is still unable to meet people's increasing requirements for the imaging quality of the camera lens, which inevitably requires adding more lens elements to improve the imaging quality of the camera lens. However, the increase of lens elements will lead to an increase in the height of the camera lens, which cannot meet the demand for thinner and lighter personal electronic products. Based on this, how to rationally design the structure of the camera lens and the parameters of the internal lenses of the camera lens, under the premise of meeting...
