In view of the existing problems of low spatial resolution and small fiel d of view in integral imaging light field acquisition and compressive light field imaging based on mas k,high hardware cost in camera array acquisition.In this paper,a method of light field acquisition and restoration based on compressive sensing from sparse camera array has been studi ed.Compressive sensi ng is applied to dense light field restoration from sparse light field viewpoints which are captu red by camera array.Two methods of sliding window and distinct window are used for light field restorati on.The dense light field is restored from the sparse light field.Finally,the re sults are analyzed.
