A pixel of a vision sensor includes a photoelectric converter configured to convert an optical signal into a current, a current-to-voltage converter configured to convert the current into a first voltage, an amplifier configured to generate an output voltage by amplifying a voltage level of the first voltage, at least one comparator configured to identify whether an event occurs based on comparing the output voltage with at least one threshold voltage, and generate an event signal based on identifying that the event occurs, and at least one counter configured to receive the event signal from the at least one comparator, obtain a count value by counting the event signal as information about an amount of change in illumination, and transmit output data comprising the count value.
