Bionic event imaging system and method thereof

A bionic event imaging system, comprising:

• a lens or lens group used for collecting light from external environment;
• a controllable blink module comprising a photomask, and a control unit used for an closing operation and/or an opening operation of the photomask;
• wherein the controllable blink module is used for controlling entering of the light of the external environment to be blocked or allowed;
• the closing operation of the photomask comprises a closing process and a closed state;
• the opening operation of the photomask comprises an opening process and an opened state;
• a dynamic vision sensor used for detecting a brightness change of an optical signal incident through the controllable blink module, and triggering an event when the brightness change exceeds a preset threshold;
• wherein the photomask correspondingly covers all or part of light detection units in the dynamic vision sensor;
• the event comprises coordinate information and time information of a triggered pixel and polarity information of the event;
• an event processing unit used for decoding an event stream generated by the dynamic vision sensor and reconstructing and generating absolute light intensity images of static scenes and dynamic scenes in the external environment.
