Abstract
Disclosed is a method for processing asynchronous signals generated by a light sensor, the sensor having a matrix of pixels, the method including: —receiving the asynchronous signals, each signal being associated with a pixel in a group of pixels in the matrix, each signal including successive events issued by the associated pixel; —upon an occurrence of an event in one of the asynchronous signals, updating an integration value associated to the group by adding an additive value to the integration value; —if the integration value is greater than a predetermined threshold, generating an event in an outputted asynchronous signal.
