Abstract:
1. A method of adjusting a signal used for the detection of a parameter carried by a signal, wherein the parameter is represented by a set of data A 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 ijt of binary numbers of n bits associated with synchronization signals defining the instant T of the space, and the position i, j, in the space, in which the signals A ijt are received, the method comprising: receiving the signal A comparing each value A generating a signal ABS generating binary threshold values DP modifying the time constant values CO calculating histograms for ABS calculating histograms for A adjusting the threshold S based on the calculated histograms of ABS so as to adjust the detection sensitivity of the variation of the parameter A; and adjusting the gain of the amplifier based on the calculated histograms of A
