Pixel collection circuit and image sensor

A pixel collection circuit, comprising:

• a photoelectric detection module configured to monitor an optical signal in real time and output a corresponding electric signal;
• a triggering generation module, a first input end of which is coupled to the photoelectric detection module, a first output end of which is coupled to an interface logic module, and which is configured to generate a triggering generation signal when a change frequency of the electric signal exceeds a predetermined frequency threshold and an amplitude of the electric signal meets a predetermined condition, and output the triggering generation signal to the interface logic module;
• and
• the interface logic module, a first input end of which is coupled to the triggering generation module, a second input end of which is coupled to a global resetting signal unit via a global resetting signal line, a first output end of which is coupled to the triggering generation module, and which is configured to output a triggering state signal upon the receipt of the triggering generation signal.
