Claim 3:
4. The dual-modality neuromorphic vision sensor according to claim 1, wherein the voltage-mode APS circuit specifically comprises: a second preset quantity of second-type photosensitive devices around the target first-type photosensitive device, each of the second-type photosensitive devices is connected to a second-type control switch in series, and at a same moment, only one second-type control switch is conducted;
the voltage-mode APS circuit further comprises a current integrator (CI), a shutter, and an analog-to-digital converter (ADC), each of the second-type photosensitive devices and the second-type control switch connected thereto in series form a device branch, and all device branches are connected in parallel and share the CI, the shutter, and the ADC; and
the CI is configured to obtain a voltage analog signal of a target capacitor in the voltage-mode APS circuit; the shutter is configured to control integration time of the CI; and the ADC is configured to convert the voltage analog signal of the target capacitor into the target voltage signal.
