<p>The invention concerns a method for determining the reference image of an imaging sensor comprising a matrix of detector pixels. The methods consists in acquiring a black image (IN) and two images (I1 and I2) acquired in linear detection zones of the sensor. The reference image is expressed: IR1 = (Rm x I1-I2)/(Rm 1) or equation (I) representing the value of the pixel of the image Ik detected by the pixel detector located at the intersection of the line of rank i and of the column of rank j of the matrix of detector pixels, and N representing the total number of pixels of the matrix.</p> |
