Claim 1:
2. The dual-modality neuromorphic vision sensor according to claim 1, wherein the first-type current-mode APS circuit further comprises: a first current amplifier, a comparator (CP), an adder, and a digital-to-analog converter (DAC); the target first-type photosensitive device is connected to the first current amplifier, and the first current amplifier is connected to an input end of the CP;
an input end of the adder is connected to the first-type control switch, and an output end of the adder is connected to the other input end of the CP; and an output end of the CP is connected to the DAC, the DAC converts an inputted specified digital signal into a specified analog signal, and outputs the specified analog signal to the first current amplifier or the adder, until the output end of the CP outputs an event pulse signal, the first-type current-mode APS circuit outputs the specified digital signal, and the specified digital signal is used for representing light intensity gradient information in the target light signal.
