AI Technical Summary
Technical Problem
Dual camera modules with adjacent camera modules suffer from magnetic interference and flare phenomena due to unnecessary light reflection, leading to suboptimal performance and increased power consumption.
Method used
A dual lens drive device with a VCM structure that integrates magnets and reduces the number of driver ICs, using a single actuator to minimize magnetic interference and power consumption, and incorporates a black mask to prevent flare by aligning infrared filters accurately during assembly.
Benefits of technology
The solution effectively reduces magnetic interference, simplifies tuning, and decreases power consumption while enhancing the reliability and performance of dual camera modules by preventing flare and improving alignment precision.
