攝像頭之手機越來越受廣大消費者青睐，在人們對數位相機、攝像機及手機攝像頭拍攝物體之影像品質提出更高要求之同時，對數位相機、攝像機及帶有攝像頭之手機等産品需求量也在增加。 [0003] 數位相機、攝像機及手機攝像頭等攝影裝置中，鏡頭是一個不可缺少之部件《數位相機、攝像機及手機攝像頭拍攝物體之影像品質主要取決於鏡頭之成像品質。對於鏡頭之製造而言’對鏡頭成像品質要求及把關之流程在於鏡頭之測試過程。 [0004]傳統之鏡頭在作影像自動化測試時’由於鏡頭之後焦距較長’檢測時無須特別去確認影像感測器是否會撞擊到鏡頭。而到了手機鏡頭等產品時，由於鏡頭之後焦距相較傳統相機之鏡頭短了許多，所以在進行影像自動化測試時，影像感測器會非常靠近鏡頭後端，這樣才能到達正確之成像位置。同時，此類鏡頭之體積一般很小，在自動化量測之測試平台上常因振動等原因産生傾斜與翹起等現象，從而會造成影像感測器按照預計行程移到量測位置時，會與鏡頭相撞，導致影像感測器或鏡頭之損壞。〇9512381(f·單編號 A01〇l 第3頁/共13頁 1013239909-0 1373686The camera's mobile phone is increasingly favored by consumers. While people are demanding higher image quality for digital cameras, camcorders and mobile phone cameras, the demand for digital cameras, camcorders and mobile phones with cameras is also high. Increasing. [0003] In a camera such as a digital camera, a video camera, and a mobile phone camera, the lens is an indispensable component. "Digital Camera, Camera, and Mobile Phone Camera The image quality of the subject depends mainly on the imaging quality of the lens. For the manufacture of lenses, the quality requirements for lens imaging and the process of checking are in the process of testing the lens. [0004] The conventional lens does not need to specifically confirm whether the image sensor will hit the lens when performing the image auto-testing because of the long focal length of the lens. When a mobile phone lens or the like is used, since the focal length of the lens is much shorter than that of a conventional camera, the image sensor is very close to the rear end of the lens during the automated image test, so that the correct imaging position can be reached. At the same time, the volume of such a lens is generally small, and the phenomenon of tilting and tilting is often caused by vibration or the like on the test platform of the automated measurement, which causes the image sensor to move to the measurement position according to the expected stroke. Colliding with the lens, causing damage to the image sensor or lens. 〇9512381(f·单号 A01〇l Page 3 of 13 1013239909-0 1373686
