Description

光圈的功能如同人眼的瞳孔一樣，可隨外在環境光強度的變化調整所需的光強度。因此，相機常藉由透過放大與縮小光圈大小來控制進入光感測元件的光線量及景深，達到高品質的成像效果，而這股風潮近年來也逐漸於智慧型手機中成形，並被視為智慧型手機所配置之相機進一步進化的次世代科技。然而，現有技術以光圈葉片及機械馬達驅動，無法達成薄型化的要求。 The function of the aperture is like the pupil of the human eye, and the required light intensity can be adjusted according to the change of the external ambient light intensity. Therefore, the camera often achieves high-quality imaging effects by controlling the amount of light and depth of field entering the light-sensing element by zooming in and out of the aperture size, and this trend has gradually taken shape in smartphones in recent years and is regarded as The next-generation technology in which the camera configured for smartphones has further evolved.
