The invention relates to matrix image sensors and more particularly relat es to a method for correcting the space noise generated by the degradation o f the physical properties of the different elementary sensitive points, or p ixels, of the matrix. The method comprises determining for each pixel, in an elementary electronic circuit associated with the pixel and by a recursive digital method, an approached value (Mij,n) of an average of the signal (Sij , n) from the pixel during a large number of images, correcting the signal f rom each pixel based on the determined approached average value and on a ref erence average value (M0), and transmitting a corrected signal (S*ij,n) outs ide the circuit associated wit the pixel.
