Latest Patents
Tjaart Opperman holds a patent for "Monitoring an event queue in an event-based vision sensor to account for event bursts." This invention involves an event-based vision sensor that comprises an array of event-based pixels. Each pixel is configured to record events based on variations of a sensed photocurrent. The system enables a request line common to pixels aligned along an axis of the array at the occurrence of an event. A request arbiter responds asynchronously to the enabled request lines by enqueuing corresponding line readout requests in a request queue. Additionally, an event readout circuit is connected to the request arbiter, configured to read out in parallel the events of a line of pixels corresponding to a current line readout request served by the arbiter. The invention also includes a queue length counter to produce the request queue length and a queue monitor to generate an event burstiness indicator. Finally, it features means to carry out a burstiness compensation action based on the event burstiness indicator.
