US Patent 11343456 Dynamic vision sensor

A dynamic vision sensor, including a first sensing pixel, another first sensing pixel, a storage capacitor, and another storage capacitor, is provided. The first sensing pixel includes a plurality of color light sensing sub-pixels, a first pixel circuit, an infrared light sensing sub-pixel, a second pixel circuit, and a ramp capacitor. The ramp capacitor is coupled to a ramp up signal. The second pixel circuit outputs a sensing result of the infrared light sensing sub-pixel to the storage capacitor. The another first sensing pixel includes another plurality of color light sensing sub-pixels, another first pixel circuit, another infrared light sensing sub-pixel, another second pixel circuit, and another ramp capacitor. The another ramp capacitor is coupled to a ramp down signal. The another second pixel circuit outputs a sensing result of the another infrared light sensing sub-pixel to the another storage capacitor.
