Systems and methods for adjusting a signal used for the detection of the movement of an object in a space represented by a set of data A.sub.ij, associated with pixels forming a multidimensional space i, j, evolving with time, and represented at a succession of instants T, wherein the data are associated with the parameter A in the form of a digital signal DATA(A), composed of a sequence A.sub.ijt of binary numbers of n bits associated with synchronization signals defining the instant T of the space, and the position i, j in this space, in which the signals A.sub.ijt are received, in which the threshold and the gain in detection sensitivity of the parameter A are adapted.The detection sensitivity of the parameter variation is also adapted.
