Abstract
The present disclosure relates to an image sensor with on-chip event-based vision sensor (EVS) denoiser. The image sensor comprises a pixel array, a denoise frame buffer, a denoise processor and an event scanner. The pixel array incudes a plurality of EVS pixels. The denoise frame buffer is configured to store an event bit map. The event bit map includes an array of units. The units have a one-to-one correspondence with the EVS pixels of the pixel array. Each unit stores an event bit. The denoise processor includes logic storing instructions that, when executed by the denoise processor, causes the image sensor to perform operations comprising: updating the event bits of the event bit map; and filtering an event stream sensed by the pixel array based on the event bit map to output an EVS data. The event scanner is configured to receive the filtered event stream from the denoise processor.
