1. A method for estimating disparity of raw focused plenoptic data, comprising: estimating an inherent shift of in-focus pixels of the raw focused plenoptic data, the inherent shift including a constant shift between samples of a same 3D point on different microlens images of the raw focused plenoptic data; determining a level of homogeneity of pixels of the raw focused plenoptic data; estimating a depth of the raw focused plenoptic data by a disparity estimation without considering the pixels of the raw focused plenoptic data which either have disparities equal to the inherent shift or which belong to homogeneous areas as a function of the level of homogeneity of the pixels of the raw focused plenoptic data.
