1. A Time-of-Flight (ToF) sensor comprising:
an array of pixels; and
processing circuitry configured to
generate a plurality of ToF exposure control signals that control at least one pixel of the array of pixels to generate a plurality of ToF pixel signals,
generate a plurality of error correcting code (ECC) exposure control signals that control the at least one pixel to generate a plurality of ECC pixel signals, and
determine a distance from an object based on the plurality of ToF pixel signals and the plurality of ECC pixel signals.
