摘要

近年來智慧型手機在照相功能發展上日新月異，影像品質方面的要求除了解析度提升外，因應遠距、低光與動態手持拍攝情境，防手振功能更是高階機種的主要訴求之一，以光學式影像穩定的抑振補償音圈馬達是主要關鍵元件。本文介紹音圈馬達與抑振驅動數位平台設計方法，具有兩大亮點。此外，針對雙鏡頭光學防手振用案例進行說明設計小廻圈流程並驗證虛擬與實體結果比對，本案例同時實現了薄化、多軸自由度與模組化技術特徵，解決了手機相機模組裡難以兼顧薄型多鏡頭與高性能的技術瓶頸。

In recent years, smartphones have been developed rapidly in camera function. Most image quality requirements have improved not only for high resolution, but also for the needs of far photographing, low light, dynamic photographing, and anti-hand vibration in high-end models. Optical image stabilization (OIS) compensation voice coil motor (VCM) is the main key component. This paper introduces the design method of the VCM and the vibration-compensated driving digital platform. Furthermore, the dual OIS VCM is a case study to illustrate the design of the small circle process and verify the virtual and physical results. This case also realizes the thinning, multi-axis degrees of freedom and modular technology features. It overcomes the bottleneck of balance between the thin dual VCM and high performance in the cell-phone camera module.
