AI Technical Summary
Technical Problem
In the existing technology, the camera lens composed of six lenses has shortcomings in terms of narrow angle and optical characteristics, especially the full angle of view does not reach below 14.5°.
Method used
By optimizing the ratio of the on-axis distance from the image side of the second lens to the object side of the third lens to the overall focal length of the camera lens, and by adjusting the focal length and thickness relationship of each lens, a specific relationship is satisfied, thereby constructing a six-lens camera lens.
Benefits of technology
It achieves a narrow viewing angle of less than 14.5° across the entire field of view and has excellent optical characteristics, making it suitable for smartphones and web cameras with high-pixel camera elements.
