A more effective confidence/uncertainty measure determination for disparity measurements is achieved by performing the determination on an evaluation of a set of disparity candidates for a predetermined position of a first picture at which the measurement of the disparity relative to the second picture is to be performed, and if this evaluation involves an accumulation of a contribution value for each of this set of disparity candidates, which contribution values depends on the respective disparity candidate and a dissimilarity to the second picture which is associated with the respective disparity candidate according to a function which has a first monotonicity with a dissimilarity associated with the respective disparity candidate, and a second monotonicity, opposite to the first monotonicity, with an absolute difference between the respective disparity candidate and a predetermined disparity having a minimum dissimilarity associated therewith among dissimilarities associated with the set of disparity candidates.
