Abstract
A light sensor has a matrix of sensing elements each providing a respective event-based signal sequence including events asynchronously produced as a function of variations of light incident on the sensing element and light level values respectively associated with at least some of the events. The method generates an image comprising pixels corresponding spatially to the sensing elements of the matrix, and determines a set of edge pixels among the pixels of the image. Pixels are selected in response to events included in the event-based signal sequences and for each selected pixel a local contrast measure is evaluated to decide whether or not the selected pixel belongs to the set of edge pixels.
