AI Technical Summary
Technical Problem
Existing mobile device camera modules are difficult to design with a small head, thus failing to meet miniaturization requirements.
Method used
The lens adopts an internal lens group design, including a first lens, a second lens, a third lens, etc., combined with a variable aperture. By controlling parameters such as lens thickness, focal length, radius of curvature and spacing, the light throughput is optimized, the size of the lens barrel is reduced, and aberrations and stray light are controlled at the same time.
Benefits of technology
It achieves miniaturization, high image quality, and large image sensor design for mobile device camera modules, reducing light loss and improving imaging performance.
