System and method for event-based double integral imaging

A camera, comprising:

• an image-generation sensor designated to generate a raw image data based on received light received over an exposure interval;
• an event-detection sensor spatially corresponding to the image-generation sensor and designated to output event data over a plurality of event frames, each event frame corresponding to a period of the exposure interval;
• memory defining:
• an event buffer storing a plurality of event values, each event value corresponding to a respective event frame of the plurality of event frames based on the event data,
• a first-integral buffer storing first integral of event data based on the event values,
• a second-integral buffer storing second integral of event data based on the first integral of event data, and
• a counter-buffer defining an event-frame count of the plurality of event frames;
• and
• a processor configured to:
• for each event frame, update the event-frame count,
• for each event frame after a first event frame, only when a current event value is different than an immediately preceding event value:
• (1) executing read/write on the first-integral buffer to update the first integral of event data based on the current event value and all preceding event values, and (2) executing read/write on the second-integral buffer to update the second integral of event data based on at least the first integral of event data and the event frame count, and
• using at least the second integral of event data, deblurring the raw image data to yield a latent deblurred image.
