Abstract
The method for processing a matrix of pixels each containing an original red, green, blue, or infrared component, comprises at least one interpolation of an interpolated component different from the original component of a pixel of interest from the components of a group of pixels neighboring the pixel of interest. The interpolation comprises: a calculation of the sum of the components of reference pixels weighted by a respectively assigned weight, the reference pixels being pixels of the group having the same original component as the interpolated component, an evaluation of the spatial uniformity of an environment, within the group of each reference pixel, a calculation of the weights assigned to the reference pixels at values which are normalized and proportional to the respective spatial uniformity.
