Abstract
An image sensor employed in a time-of-flight (TOF) sensing system includes a pixel array including plural pixels, each pixel including at least one photo diode and each pixel generating an amount of charge corresponding to an incident light, comparing circuitry configured to compare voltage levels, each voltage level individually changed based on the amount of charge outputted from each pixel, with a reference voltage to output a comparison result, and calibration circuitry configured to adjust the voltage levels equally based on the comparison result.
