Image sensor (mic) intended to be installed in a carrier (sat) moving on the - the top of a scene observed, said sensor comprising a plurality of matrices of the detection of images of the type of tdi (m1, m2), aligned along the direction of displacement (d) of said carrier and a circuit for processing the signals (these) generated by the dies, in which the signal processing circuit is configured to: - calculate the correlations of the vectors of image data (vd1, vd2) supplied by the various matrices of the detection of pictures; - deduce therefrom a shift between the vectors of pictures; - correct the offset by readjusting the vectors of the image; and - integrate the vectors of image data repositioned in order to supply at its output a vector image data accumulated. Optical instrument spatial or airborne of acquisition of images, comprising such an image sensor.
