1. A method for providing a disparity map of values in a sequence of pairs of images, each pair of images comprising a first image (L t ) and a second image (R t ), the method comprising cyclically: detecting still zones in a current image by comparison of the first image (L t ) of a current pair and the first image (L t-1 ) of a previous pair, providing current disparity estimations (D t L ) for a current pair of images, from an estimation process based on the current pair of images, at least for pixels that do not belong to a still zone, assigning current disparity values from the estimation process for pixels of the first image of the current pair that do not belong to a still zone, assigning a modified disparity value (FD t-1 L ) to a pixel which belongs to a still zone, and checking coherency of still zones in the current pair, comprising: determining still zones in a second image of the current pair; determining destination pixels of the second image of the current pair, said destination pixels corresponding to respective pixels of the still zones of the first image of the current pair shifted by the disparity estimations of the respective pixels, and discarding from the still zones of the first image of the current pair those pixels that have a destination pixel which is not in a still zone of the second image of the current pair.
