Claim One:
1. A method of processing images in a system for capturing a series of images of a scene comprising an image capture device having a matrix of flux sensors oriented along a sighting axis (z), said image capture device comprising a stabilization module which stabilizes the sighting axis of the captured images, said sighting axis being subjected to a specified cyclic motion having an amplitude of n pixels in each cycle at the flux sensor matrix, n being a whole number greater than 2 and smaller than n max , n max being determined in such a way that the images captured in each cycle have a predominantly common part; said method comprising the following steps, applied to a series of successive images (N i−k ) captured during a cycle: / 1 / repeating steps /i/ and /ii/ from the first captured image to the last captured image of said series and an intermediate image (I intermediate ) is obtained: /i/ registering a subsequent image (N i+1 ) of said series of images on a preceding image (N i ) as a function of the defined motion; /ii/ correcting a spatial noise due to the flux sensors and affecting the common part of the images of the preceding and subsequent images as a function of at least one measured offset between a value of a reference pixel (P 1 ) in the common part of the preceding image and a value of a subsequent pixel (P 2 ) which represents the same point of said scene as said reference pixel in said common part of the subsequent image; / 2 / obtaining a corrected captured image of the scene by applying a convolution product between said intermediate image and a corrective point spread function (PSF global ), said corrective point spread function being determined according to the defined motion.
