Abstract
A vision sensor chip includes a photoelectric conversion element that generates a current based on an incident light, a current-voltage (I-V) converter that converts the current into a voltage, an AC coupling capacitor directly connected to the I-V converter, an open-loop amplifier that includes a reset switch and amplifies a voltage provided by the I-V converter via the AC coupling capacitor. An event detection block detects motion according to a change in the amplified output voltage and generates first and second detection signals. A reset signal generator generates a reset signal controlling operation of the reset switch in response to first and second control signals respectively related to the first and second detection signals.
