METHOD OF PREPARING HISTOGRAMS OF A SENSOR SIGNAL FROM AN ARRAY OF SENSORS, IN PARTICULAR PROXIMITY SENSORS, AND CORRESPONDING DEVICE
Abstract:
A method includes preparing a first histogram from the emission of initial optical radiation and including at least one processing iteration performed at a rate of a clock signal having an internal period equal to a sub-multiple of the optical period a sensor signal and a reference signal. Successive iterations of histogram preparation are performed so that in each iteration a time shift of the initial optical radiation is provided by a first fraction of the internal period until at least one portion of the internal period is covered to obtain an additional histogram at the conclusion of each iteration. A numerical combination of the first histogram and additional histograms is performed to obtain a final histogram having a finer time granularity than that of the first histogram.
