摘要： 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.

摘要： An image sensor, employed in a time-of-flight (TOF) sensing system, includes a pixel array including a plurality of pixels arranged in plural rows and plural columns, each pixel generating an amount of charge in response to an incident light, and first driving circuitry configured to supply a driving control signal to each pixel via the plural columns. The first driving circuitry is configured to supply the driving control signal via one of odd and even columns.
