OPIC優化運算元用於百萬畫素手機相機變焦鏡頭設計探討

Abstract

本論文主要是利用OPIC 優化運算元，試圖找出單移動內部一片透鏡即可完成系統變焦的新型內變焦鏡頭，探討百萬畫素手機相機內變焦鏡頭的最佳解設計。利用光學模擬軟體OLSO 根據物理限制與系統規格加入限制條件，限制鏡組內部移動一片透鏡的條件下完成系統變焦(內變焦系統)，建立在此架構之下，搭配我們所設計的優化流程，使用OLSO 的優化功能及我們所設定之OPIC 誤差函數，試圖尋求出規格下之最佳解，並歸納出何種鏡片形式會有最好的系統整體表現。

We explore the mobilephone camera zoom lens, which have three or four elements can be moved only one element to achieve the 2X optical zoom ratio with typical mega-pixel sensor format by using OPIC merit function. We proposed a flow for optimization of lens design in the zoom lens application, which combines OPIC merit function and Damped Least Square (DLS) supposed in OLSO. And we identify the lens form that can achieve the 2X optical zoom ration by moving only one element.
