In one embodiment, it is proposed a plenoptic camera comprising a color filter array positioned on a pixel sensor, said color filter array comprising a set of unit elements, each unit element covering M × M pixels of said pixel sensor, with M an integer such that M ‰¥ 2, said plenoptic camera further comprising a set of micro-lens, each micro-lens delivering a micro-lens image on said pixel sensor with a diameter equal to p = k.M, with k an integer greater than or equal to one. The color filter array is remarkable in that said set comprises an initialization unit element being associated with a matrix c m , n 0 ‰¤ m < M 0 ‰¤ n < M indicating a filter repartition, where each coefficient c m,n is associated with a filter value, and in that the other unit elements are associated with matrixes with coefficients set to c ( x + i )mod M ,( y + j )mod M , for corresponding pixel ( x, y, i, j ) on said sensor, where indexes x, y relate to indexation of a pixel in said sensor, and indexes i, j relate to indexation of a micro-lens in micro-lens array. |
