Abstract
A method for obtaining a refocused image from a 4D raw light field data for a given focus (z) is described. The method is remarkable in that it comprises applying a shift correction parameter on shifted and summed images from said 4D raw light field data, the shifted and summed images being defined as a function of the given focus (z), and the shift correction parameter (Δ) including, for at least a part of pixels of at least two sub-aperture images derived from at least one 4D light field data of a test-chart image, determined shifts for pixels belonging to the part of pixels between the at least two sub-aperture images, the test-chart image comprising patterns adequate to compute disparities between the sub-apertures images.
