Abstract
Abstract Most of the Camera Phone are using digital auto-focus.Even if the Camera Phone with optical auto-focus function has been out on the market,it is too expensive to popularize.Varioptic announced that they invented a new device named liquid lens having optical auto-focus function.Different from the traditional method to move lens module by VCM,liquid lens is driven by voltage-control.We can achieve auto-focus to maintain image quality without moving lens module.We provide a new simulating method with CCL programming by OSLO to build a dynamic liquid lens model.Combined liquid lens model with fixed lens,we successfully design 3MP Mobile Phone,F/3.6、HFOV=±31°、Focal Length is 4.78~4.62mm.In any different distances ( 10cm ~ Infinite ) of object,we can maintain image quality by continuous auto-focus
