An image sensor is provided. The image sensor includes a pixel array including first and second pixels, the first and second pixels receiving the same transfer gate signal and outputting first and second signal voltages, respectively, a transfer gate driver receiving first and second voltages and generating the transfer gate signal, the transfer gate signal having the first voltage as its maximum voltage and having the second voltage as its minimum voltage and a compensation module detecting a variation in the second voltage, generating a compensation voltage based on the variation in the second voltage, and performing a compensation operation.

Image sensor

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.

Vision sensor chip with open-loop amplifier, operating method, and data processing system including same

A binary complementary metal-oxide-semiconductor (CMOS) image sensor includes a pixel array and a readout circuit. The pixel array includes at least one pixel having a plurality of sub-pixels. The readout circuit is configured to quantize a pixel signal output from the pixel using a reference signal. The pixel signal corresponds to sub-pixel signals output from sub-pixels, from among the plurality of sub-pixels, activated in response to incident light.
