Abstract With the increasing application of light field, especially in the light field display field (LFD), more and more light field data are required. However, there are some disadvantages for current light field acquisition methods, such as high hardware cost, low spatial resolution and other defects. A novel light field acquisition method using external mask and compressive sensing theory is presented. Different from the conventional methods with the camera array or the light field camera based on the micro-lens array, an external mask is pasted on the large aperture lens of an ordinary camera, and the 3D scene is captured at several typical positions. The compressive sensing theory is introduced to recover the original light field data ( 5 × 5 ) even though the photos captured by camera is vignette and with a limited field-of-view (F.O.V) of the lens. Simulation is carried to confirm our method with a good SSIM. The acquired light field data with our method is demonstrated with a light field display, and the validity of the proposed method is proved.
