摘要： A system is provided in which the spatial values (S1 to Sn) of the physical quantity are represented by measurement pulses (I1 to In), the temporal ordering of which represents the values, which are processed by processing units (U1 to Un) arranged in at least one row and each include an output (SOR1 to 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.

摘要： The invention concerns a system wherein the spatial values (S1 to Sn) of the physical quantity are represented by measurement pulses (I1 to In) whereof the temporal ordering represents said values. The system comprises a plurality of processing units (U1 to Un) for processing said measurement pulses. They are arranged in at least one row and include each an output (SOR1 to SORn) whereon, during successive processing cycles, a measurement pulse processed therein can be delivered to form the output signal (SU) of the system. The invention is characterized in that each processing unit (U1 to Un) comprises inhibiting means (BI) for, in other units of the row and during a given processing cycle, inhibiting the passage to the outputs (SOR1 to SORn) of said other units respective measurement pulses processed therein and hence preventing them from forming the output signal (SU), if said measurement impulses are temporally ordered later in the given processing cycle than the one processed in the unit concerned.

摘要： 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.

摘要： The invention relates to a method of calculating the local contrast at each pixel (PC) in a network (Mp) of photosensitive pixels which are arranged in at least one dimension (x, y). The inventive method consists in, during successive image acquisition cycles, producing a signal which is representative of the local luminance at each pixel, said luminance-representative signals being integrated values of luminance values sensed by the respective pixels (pC, pG, pD, pH, pB). The inventive method consists in: sampling the integrated values of the signals representing the luminance values at the pixels adjacent (pG, pD, pH, pB) to a considered pixel (pC), said sampling taking place at an instant in the cycle when the integrated value of the luminance at the considered pixel (pC) is equal to a pre-determined reference value; and determining the local contrast at the considered pixel (pC) on the basis of values thus sampled.
