隨著多媒體技術之發展,數碼相機、攝影機越來越為廣大消費者所青睞,在人們對數碼相機、攝影機追求小型化之同時,又希望在同一位置可拍攝遠近距離不同之影像,且獲得清晰之圖像畫面,而且應用於移動電話之數碼相機模組還要滿足輕薄短小之要求,因此調焦相機應運而生。With the development of multimedia technology, digital cameras and video cameras are becoming more and more popular among consumers. While people are pursuing miniaturization of digital cameras and cameras, they hope to capture images with different distances at the same location and obtain clear images. The image camera, and the digital camera module applied to the mobile phone also needs to meet the requirements of lightness and thinness, so the focus camera came into being.
傳統相機中之鏡頭模組在調焦過程中,往往需要調整鏡頭模組與影像傳感裝置之間之距離,在此過程中,需要鏡頭模組軸向總長度發生變化或鏡頭模組沿光軸方向移動,所以在鏡頭座中必須設置可以讓鏡頭模組來回活動之空間,從而增大了整個相機體積。In the focusing process of a conventional camera, it is often necessary to adjust the distance between the lens module and the image sensing device. In this process, the total axial length of the lens module needs to be changed or the lens module is along the light. The axis moves, so you must set a space in the lens mount that allows the lens module to move back and forth, thus increasing the overall camera volume.
有鑒於此,有必要提供一種在調焦時能保持鏡頭模組總長度與位置不變之鏡頭模組。In view of this, it is necessary to provide a lens module that can maintain the total length and position of the lens module during focusing.
