Event filtering in an event sensing system

Event filtering in an event sensing system

An event sensing system includes a pixel array including a plurality of event driven pixel circuits configured to be illuminated by incident light. The event driven pixel circuits are configured to generate a event current in response to a detection of a event in the incident light. Output signals o...

description An event sensing system includes a pixel array including a plurality of event driven pixel circuits configured to be illuminated by incident light. The event driven pixel circuits are configured to generate a event current in response to a detection of a event in the incident light. Output signals of a row of the pixel array are configured to be read out from the row of the pixel array to a line buffer in response to the detection of the event in the incident light. A random number generator is configured to randomly generate a filtering mask. A mask circuit is the output signals of the row of the pixel array from the line buffer and the filtering mask from the random number generator to filter the output signals of the row of the pixel array in response to the filtering mask.
