1. A method for correcting chromatic aberrations of a color image composed of a plurality of digitized color planes, the color image having been produced by means of an optical system, the method comprising:

  • modeling and correcting, at least partly, the geometric anomalies composed of deviations between geometric defects of the digitized color planes, to obtain corrected digitized color planes, wherein it is possible to establish a correspondence between the corrected digitized color planes; and

    combining the corrected digitized color planes to obtain a color image corrected completely or partly for the chromatic aberrations,wherein the step of modeling and correcting further comprises;

    producing, by means of an appliance or an appliance chain, an image of a reference scene, the image exhibiting defects,producing, from the reference scene, a virtual reference,establishing a bijection between the image and the virtual reference,calculating projections of the virtual reference onto three digitized color planes R, G and B, using a same mathematical projection for each of the three digitized color planes,calculating formatted information comprising mathematical projections, andcorrecting the chromatic aberrations of the image based on the formatted information.
