Method for encoding at least one matrix of image views obtained from data acquired by a plenoptic camera, and corresponding electronic devices

A method for decoding at least one matrix of encoded image views obtained from data acquired by a plenoptic camera, wherein the encoded image views of said at least one matrix of image views comprise encoded blocks, and said method being characterized in that it comprises, for a given encoded image view of said at least one matrix:

• obtaining a predictor block and a residual block;
• obtaining, from metadata provided with said encoded image view, flux variation parameters associated with characteristics of a micro lens array and a pixel sensor of said plenoptic camera;
• and
• obtaining pixels of a block to be decoded according to said residual block, said predictor block and the flux variation parameters.

An electronic device for encoding at least one matrix of image views obtained from data acquired by a plenoptic camera, wherein image views of said matrix of image views are partitioned into blocks, the electronic device comprising a processor and at least one memory unit coupled to said processor, and for a given image view of said at least one matrix of views, the processor is configured to:

• obtain at least one block to be encoded and a matching block, wherein a difference between said at least one block to be encoded and said matching block fulfills a block matching criterion;
• determine flux variation parameters associated with characteristics of a micro lens array and a pixel sensor of said plenoptic camera;
• determine a residual block regarding said at least one block to be encoded and said matching block, that comprises a use of modified pixels of said least one block to be encoded and modified pixels of said matching block according to the flux variation parameters;
• encode said residual block to form an encoded residual block;
• and
• provide, along with said encoded residual block, metadata including said flux variation parameters.
