METHOD FOR CORRECTING THE SPATIAL NOISE OF A MATRIX IMAGE SENSOR

The invention relates to matrix image sensors, and it relates more particularly to a method for correcting the spatial noise generated by the dispersion of the physical properties of the different individual sensitive dots, or pixels, of the matrix. For each pixel, in an individual electronic circuit associated with the pixel, a recursively digital method is used to determine an approximate value (Mij,n) of an average of the signal Sij,n obtained from the pixel during this large number of images; the signal obtained from each pixel is corrected according to the determined approximate average value and according to a reference average value (M0), and a corrected signal S*ij,n is transmitted from the circuit associated with the pixel.
