先拍攝後對焦

美國科學家發明新方法去調整進入相機後既光線,可以配合軟體去改變每個晶片收到既數據,從而重新建立一幅清晰既圖片。

Pat Hanrahan and his team at Stanford University have figured out how to adjust the light rays after they have reached the camera. They inserted a sheet of 90,000 lenses, each just 125 micrometres across, between the camera’s main lens and the image sensor. The angle of the light rays that strike each microlens is recorded, as well as the amount of light arriving along each ray.
