The invention concerns a three dimensional (3D) display apparatus of the integral photography type comprising a passive array (32) of points and an array (30) representing the image to be displayed, this second array comprising a set of subarrays. Each subarray is associated with a corresponding point of the passive array, and each point of each subarray contains an information about a point of the 3D image to be displayed. A light ray from a point of a subarray to the associated point of the passive array virtually converges to the corresponding point of the 3D image to be displayed. To each point of said passive array (32) are associated optical controllable means (34) receiving the light rays coming from the points of the subarray and passing through said point of the passive array and able to output during n subframes, n being at least equal to 2, light rays in n angular spaces, each angular space providing light rays coming from all the points of the subarray.
A three dimensional display apparatus of the integral photography type comprising a passive array of points and an array representing the image to be displayed, this second array comprising a set of subarrays, each subarray being associated with a corresponding point of the passive array, and each point of each subarray containing an information about a point of the 3D image to be displayed, a light ray from a point of a subarray to the associated point of the passive array virtually converging to the corresponding point of the 3D image to be displayed, wherein to each point of said passive array are associated optical controllable means receiving the light rays coming from the points of the subarray and passing through said point of the passive array and able to output during n subframes, n being at least equal to 2, light rays in n angular spaces, each angular space providing light rays coming from all the points of the subarray.
A three dimensional (3D) image capturing apparatus of the integral photography type comprising a passive array of points or slits or lenses and an array of photodetectors for capturing the image, this second array comprising a set of subarrays, each subarray being associated with a corresponding point of the passive array, and each photodetector of each subarray being able to detect an information about a point of the 3D image to be captured, wherein said apparatus comprises controllable optical means provided in front of the passive array for each subarray and the corresponding point of the passive array, these optical controllable means being controlled during n subframes dividing each image frame, the control being such that it divides the detected angular space into n subangular spaces, each subangular space at the input of the optical controllable means providing an output covering the whole angular space delimited by all the points of the subarray and the corresponding point of the passive array.
