A method and a device for encoding a signal representative of a light-field content

A METHOD AND A DEVICE FOR ENCODING A SIGNAL REPRESENTATIVE OF A LIGHT-FIELD CONTENT The present invention relates to the transmission of sets of data and metadata and more particularly to the transmission of light-field contents. Light-field data take up large amounts of storage space which makes storage cumbersome and processing less efficient. In addition light-field acquisition devices are extremely heterogeneous and each camera has its own proprietary file format. Since acquired light-field data from different cameras have a diversity of formats a complex processing is induced on the receiver side. To this end, it is proposed a method for encoding a signal representative of a light-field content in which the parameters representing the rays of light sensed by the different pixels of the sensor are mapped on the sensor. A second set of encoded parameters are used to reconstruct the light-field content from the parameters representing the rays of light sensed by the different pixels of the sensor. 20 0 LF DATA 150 \00110 20FORMATOR 150 LF DATA 1155 PROCESSOR 15 z )2 UI 160 < /165
