摘要： An apparatus (500) comprises: - an imaging device (CAM1) comprising an input element (100), a focusing unit (300) and an image sensor (DET1), wherein the input element (100) has a symmetry axis (AX1), wherein a viewing region (ZONE1) surrounds the input element (100), and wherein the imaging device (CAM1) is arranged to form an annular image (IMG1) of the viewing region (ZONE1) on the image sensor (DET1), - a curved diffractive element (G1) to provide a first diffracted light ray (LR2a) and a second light ray (LR2b, LR2c) by diffracting light (LB1) received from a first object point (P0) located in the viewing region (ZONE1) such that the first diffracted light ray (LR2a) propagates towards the axis (AX1) in a first azimuthal direction (j1), and such that the second diffracted light ray (LR2b, LR2c) propagates towards the axis (AX1) in a second different azimuthal direction (j2), - wherein the imaging device (CAM1) is arranged to form a first image point (P1a) of the first object point (P0) by focusing light of the first diffracted light ray (LR2a) to the image sensor (DET1), and the imaging device (CAM1) is arranged to form a second different image point (P1b, P1c) of the first object point (P0) by focusing light of the second diffracted light ray (LR2b, LR2c) to the image sensor (DET1).

摘要： A method for encoding a raw lenselet image (f), comprising a receiving phase (705), wherein at least a portion of a raw lenselet image (f) is received, said image (f) comprising a plurality of macro-pixels (650, 1320, 1340), each macro-pixel (650, 1320, 1340) comprising pixels corresponding to a specific view angle for the same point of a scene and an output phase, wherein a bitstream (f d ^) comprising at least a portion of an encoded lenselet image (f) is outputted. The method comprises an image transform phase (710), wherein the pixels of said raw lenselet image (f) are spatially displaced in a transformed multi-color image (660) having a larger number of columns and rows with respect to the received raw lenselet image, wherein dummy pixels (610, 620) having undefined value are inserted into said raw lenselet image (f) and wherein said displacement is performed so as to put the estimated center location of each macro-pixel (650, 1320, 1340) onto integer pixel locations. Moreover, the method comprises a sub-view generation phase, wherein a sequence of sub-views (f d ') is generated, said sub-views (1310, 1510, 1620) comprising pixels of the same angular coordinates extracted from different macro-pixels (650,1320,1340) of said transformed raw lenselet image (f). Finally, the method comprises a graph coding phase, wherein a bitstream (f d ^) is generated by encoding a graph representation of at least one of the sub-views (1310, 1510, 1620) of said sequence (f d ' ) according to a predefined graph signal processing (GSP) technique. The method comprises outputting said graph-coded bitstream (f d ^) for its transmission and/or storage.
