Abstract
In one embodiment, it is proposed a method for obtaining at least one sub-aperture image being associated with one view, from raw light field data corresponding to recorded data by an array of pixels sensors positioned behind an array of micro-lenses in a light field camera, each of said pixel sensor recording a linear mixing of up to four different views. The method is remarkable in that it comprises applying a signal separation process on said raw data by using an inverse of a mixing matrix A, said mixing matrix comprising coefficients that convey weighting information of said up to four different views recorded by a pixel sensor.

A method comprising:
- recording raw light field data by an array of pixel sensors positioned behind an array of micro-lenses in a light field camera, wherein each pixel sensor records a linear mixing of up to four different views
- obtaining at least one sub-aperture image associated with one view by applying a signal separation process on the raw data by using an inverse of a mixing matrix A, wherein the mixing matrix A comprises coefficients that convey weighting information of the up to four different views, and wherein the mixing matrix A is representative of a relationship between the data recorded by the array of pixel sensors and the at least one sub-aperture image.
An electronic device comprising a memory and at least one processor coupled to the memory, wherein the at least one processor is configured to:
- record raw light field data by an array of pixels sensors positioned behind an array of micro-lenses in a light field camera, wherein each pixel sensor records a linear mixing of up to four different views;
- obtain at least one sub-aperture image associated with one view by applying a signal separation process on the raw data by using an inverse of a mixing matrix A, wherein the mixing matrix A comprises coefficients that convey weighting information of the up to four different views, and wherein the mixing matrix A is representative of a relationship between the data recorded by the array of pixel sensors and the at least one sub-aperture image.
A method comprising:
- recording, by an array of pixel sensors, raw light field data representative of an image through an array of micro-lenses, wherein each pixel sensor of the array of pixel sensors records data comprising a linear mixing of up to four different views of the image;
- obtaining at least one sub-aperture image associated with one view of the image by applying a signal separation process on the raw data by using an inverse of a mixing matrix A, wherein the mixing matrix A comprises coefficients that convey weighting information of the up to four different views, and wherein the mixing matrix A is representative of a relationship between the data recorded by the array of pixel sensors and the at least one sub-aperture image.
