摘要： A plenoptic camera (1) comprising a camera lens (10), a microlens array (11) and a photosensors array (13). An optical device (14) is arranged before the camera lens (10) according to a light-traveling direction of a light flux entering the plenoptic camera, the optical device (14) comprising a first layer that is controllable between a transmissive mode and a scattering mode and at least one light source arranged at a border of said optical device (14).
Method of controlling the plenoptic camera.-

摘要： A method and device for encoding data representative of a 3D representation of a scene into a bitstream, the 3D representation being according to a range of points of view. To reach that aim, at least a depth map associated with at least a part of the 3D representation is generated according to at least one parameter representative of at least a 2D parametrization associated with the at least a part and data associated with at least a point comprised in the at least a part; at least a texture map associated with the at least a part is generated according to the at least a parameter and data associated with the at least a point; a first information representative of variation of quantization parameter within the at least a depth map and/or said at least a texture map is obtained according to a region of interest of the 3D representation; and the at least a depth map is encoded into a first syntax element of the bitstream, the at least a texture map is encoded into a second syntax element of the bitstream, the at least a parameter is encoded into a third syntax element, the first information is encoded into a fourth syntax element and a second information representative of a mapping between the at least a 2D parametrization and corresponding at least a depth map and at least a texture map is encoded into a fifth syntax element.
Corresponding decoding method and device are also disclosed.
