Abstract
In one implementation, a system includes an event sensor with a pixel array and an image pipeline. The pixel array is configured to operate a first subset of pixels in an active state and a second subset of pixels in an inactive state. The event sensor is configured to output pixel events. Each respective pixel event is generated in response to a specific pixel within the first subset of pixels detecting a change in light intensity that exceeds a comparator threshold. The image pipeline is configured to consume image data derived from the pixel events and communicate feedback information to the event sensor based on the image data. The feedback information causes a pixel within the first subset of pixels to transition from the active state to another state.
