Problems solved by technology

[0004] With the continuous development of portable electronic products such as smartphones, higher requirements are put forward for imaging lenses, and most of the existing technologies are wide-angle lenses of about 120 degrees. After the distortion algorithm is corrected, the FOV is about 110 degrees, which cannot meet the requirements. Future technology will have greater demand for wide-angle shooting on mobile phones

Abstract

The invention relates to an imaging system which comprises a first lens (E1), a second lens (E2), a third lens (E3), a diaphragm (STO), a fourth lens (E4), a fifth lens (E5), a sixth lens (E6) and a seventh lens (E7) which are sequentially arranged from an object side to an image side along an optical axis, and the first lens (E1), the second lens (E2), the third lens (E3) and the sixth lens (E6) all have focal power; the fourth lens (E4) has negative focal power, the fifth lens (E5) has positive focal power, and the seventh lens (E7) has negative focal power. The imaging system has excellent characteristics of ultra wide angle and the like, so that more photographing requirements can be met.

Description

Technical field [0001] The present invention relates to the field of optical imaging, and more particularly to an imaging system. Background technique [0002] With the rapid development of the smartphone, the camera innovation has become the weight of the innovative technology. Its innovation direction mainly includes the following points: 1. High-pixel gradually penetration; 2.Video video camera is gradually infiltrated; 3.TOF potential outbreak ; 4. Rapid growth in front of the front; 5. Rear four-fitting further infiltration; 6. Screen camera technology breakthrough. These innovations belong to the development trend of future smartphone camera technology. [0003] The wide-angle lens is currently a multi-camera imaging lens because it is widely used in large scene landscape photography. Specific, wide-angle lens is large, the view is wide, the scene observed from a visual point is much larger than the human eye in the same point of view; the depth of field can show a consider...
