Embodiments of the present disclosure provide a cone-rod dual-modality neuromorphic vision sensor, including: a first preset quantity of voltage-mode active pixel sensor (APS) circuits and a second preset quantity of current-mode APS circuits, where each of the voltage-mode APS circuits includes a first-type photosensitive device, and each of the current-mode APS circuits includes a second-type photosensitive device. The voltage-mode APS can output a target voltage signal representing light intensity information in a target light signal. The obtained target voltage signal represents the light intensity information with a higher precision, and therefore an image with higher quality can be obtained, that is, the image has a higher signal-noise ratio. The voltage-mode APS can output a specified digital signal representing light intensity gradient information in the target light signal, to ensure performance indicators such as an image dynamic range and a shooting speed of the neuromorphic vision sensor, thereby making the neuromorphic vision sensor more stable and robust.
