Abstract
A vision sensor includes a pixel array including a plurality of pixels, a voltage generator configured to generate a reset bias voltage provided to each of the plurality of pixels, a temperature comparing circuit configured to output a switching setting value according to a result of comparing temperature information with at least one reference temperature value, and a voltage level controller configured to generate a reset bias setting signal based on the switching setting value. The reset bias setting signal adjusts a voltage level of the reset bias voltage.
