A system is provided in which the spatial values (Sto Sn) of the physical quantity are represented by measurement pulses (Ito In), the temporal ordering of which represents the values, which are processed by processing units (Uto Un) arranged in at least one row and each include an output (SORto SORn). During successive processing cycles, a measurement pulse processed therein can be delivered to form the output signal (SU) of the system. Each processing unit includes an inhibiting unit (BI) for, in other units and during a given processing cycle, inhibiting the passage to the outputs of the other units respective measurement pulses processed therein and hence preventing them from forming the output signal, if the measurement impulses are temporally ordered later in the given processing cycle than the one processed in the unit concerned.

System for spatial analysis of a physical quantity

A method of detecting relative movement between a scene from which radiation emanates and a matrix of pixels observing the scene and capable of detecting the radiation, each pixel of the matrix measuring contrast vector information representative of the observed scene monitors the evolution of the contrast vector information in each pixel of the matrix During a first time interval, it detects among the pixels the pixel whose magnitude vector information value is greater than the magnitude vector information value of the adjacent pixels. During a second time interval consecutive to the first time interval it detects if the magnitude vector information of the pixel whose value was at a maximum during the first time interval has decreased. It generates output signals representative of the relative movement if a decrease is detected.
