Disclosed herein is a device (10; 20; 30; 40; 50; 60; 70; 80; 90; 100) for the plenoptic reconstruction of indirect images of an object (OBJ). Unlike prior art techniques, it is possible to overcome the problem of focusing the indirect image in the case of an object (OBJ) positioned outside a focusing plane without requiring new acquisitions of the image itself, thanks to the features of the plenoptic image acquisition device PC. Although the indirect image is visible only after the evaluation of the correlations, if such image is out of focus it is possible to perform a refocusing by using the data available in the plenoptic acquisition. Therefore, it becomes possible to reconstruct the indirect image of objects irrespective of their location, as well as of moving objects
