Abstract
There are several types of plenoptic devices having a proprietary file format. At present, there is no standard supporting the acquisition and transmission of multi-dimensional information for an exhaustive over-view of the different parameters upon which a light-field depends. As such, acquired light-field data for different cameras have a diversity of formats. The notion of pixel beam, which represents a volume occupied by a set of rays of light in an object space of an optical system of a camera is introduced. The method according to the invention enables to provide data representative of a bokeh associated to a pixel beam. Such data representative of bokeh associated to a pixel beam enables the displaying of an image with good bokeh properties.
