METHOD FOR DOWNSAMPLING A SIGNAL OUTPUTTED BY AN ASYNCHRONOUS SENSOR

摘要

The present invention relates to a method for processing asynchronous signals generated by a light sensor, the sensor having a matrix (100) of pixels, the method comprising: - receiving the asynchronous signals (401), each signal being associated with a pixel in a group of pixels (101a, 102a, 101b, 102b) in the matrix, each signal comprising successive events issued by the associated pixel; - upon an occurrence of an event in one of the asynchronous signals, updating (405) an integration value associated to said group by adding an additive value to the integration value; - if the integration value is greater than a predetermined threshold (406), generating (408) an event in an outputted asynchronous signal.
