Claim Text:
1. A method for processing a light-field image, comprising: acquiring a light-field image; acquiring an occlusion tag function for each of a plurality of unit images in the light-field image, and determining a cost function for offset estimation of each unit image according to intensity change information and gradient change information for each unit image in the light-field image and the occlusion tag function of each unit image; acquiring an offset of each unit image in the light-field image using the cost function; and reconstructing a high-resolution light field using the offset of each unit image, wherein the determining a cost function for offset estimation comprises: determining a cost function Γ χ is a pixel coordinate set of each unit image, Φ( ) is a concave function for acquiring robustness, ∇ is a gradient function, Γ
