    Abstract: A fast method of color interpolation of pixels of an image acquired by a color filtered digital sensor uses a very simple cost function that nevertheless produce interpolated images of good quality. The cost function is computationally simpler because it does not require the calculation of powers and square roots. An efficient triangulation algorithm that may be executed in far less time than prior art triangulation processes, while practically ensuring the same performances. The peculiarity of this triangulation algorithm consists in that on average it requires only two iteration steps, while the most accurate prior triangulation algorithm is completed only after four iteration steps. Optionally, the interpolation process may be followed by an anti-aliasing processing that effectively removes color artifacts that may be created during the interpolation process.

    Abstract: A method for obtaining a high-resolution digital image from a plurality of starting images P,S formed by pixel matrices and acquired at a lower resolution. The method comprises a phase of combining the plurality of starting images P,S to generate a provisional high-resolution image HR formed by a pixel matrix. The method also comprises a calculation phase to associate a respective error with at least a part of the pixels of the provisional image HR , said calculation phase providing a first error associated with at least one first pixel, and a phase of at least partially processing the provisional image by modifying the pixels of this image on the basis of the respective errors associated with them. The method is characterized by the fact that the calculation phase includes the phase of: calculating a second error to associate with at least one second pixel situated in the vicinity of said first pixel in the matrix (HR ), said second error being calculated by using the first error associated with said at least one first pixel.
