AI Technical Summary

Technical Problem

In existing camera modules, stray light reflected onto the image sensor leads to a decrease in image quality. Conventional solutions are ineffective at eliminating stray light and increase the size of optical path deflection elements.

Method used

Multiple microstructures are set on the optical path deflection element, and each microstructure corresponds to at least one reflective surface. Stray light is reflected along the incident surface under the action of the microstructure, reducing the amount of stray light emitted to the image sensor. At the same time, the microstructure extends in an arc or zigzag shape to improve the diffuse reflection effect.

Benefits of technology

It effectively reduces stray light interference, improves imaging quality, and helps to reduce the size of optical path reversal elements, making them simple to manufacture and cost-effective.
