Abstract
The invention relates to a system and a method for correcting the chromatic aberrations (1) of a color image (3) composed of a plurality of digitized color planes (4). This color image (3) is assumed to have been produced by means of an optical system (5). According to the invention, the geometric anomalies of the said digitized color planes (4) are modeled and corrected, at least partly, in such a way as to obtain corrected digitized color planes (17). The corrected digitized color planes (17) are then combined in such a manner as to obtain a color image (19) corrected completely or partly for the chromatic aberrations (1). The invention is applicable to photographic or video image processing, in optical devices, industrial controls, robotics, metrology, etc.
