In one embodiment, an event driven pixel comprises a photosensor, a photocurrent-to-voltage converter, and a difference circuit. The difference circuit includes (a) a first circuit branch configured to sample a reference light level based on a voltage output by the photocurrent-to-voltage converter, and to output a first analog light level onto a first column line that is based on the reference light level; and (b) a second circuit branch configured to sample a light level based on the voltage, and to output a second analog light level onto a second column line that is based on the light level. A difference between the second analog light level and the first analog light level indicates whether the event driven pixel has detected an event in an external scene."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Low power event driven pixels with passive, differential difference detection circuitry, and reset control circuits for the same","description":"Low power event driven pixels with passive, differential difference detection circuitry (and reset control circuits for the same) are disclosed herein.
