Abstract:
In some embodiments, a method is performed at a device with a processor, non-transitory memory, and an event camera including pixel sensors distributed across an area. The method includes converting an event stream from a pixel sensor over a first time period into event frames by dividing the first time period into sub-periods, and binning pixel events of the event stream, where each of the sub-periods is associated with a frame sub-period identifier. The method further includes addressing the pixel sensors by sub-dividing the area into tiles, where each of the tiles includes a grouping of the pixel sensors, and a tile address of a particular pixel sensor is a combination of a tile identifier and a position locator of the particular pixel sensor. The method further includes encoding the pixel events as a function of a tile address, a frame sub-period identifier, and a brightness indicator value.
