TIME OF FLIGHT SENSOR, THREE-DIMENSIONAL IMAGING DEVICE USING THE SAME AND METHOD FOR DRIVING OF THREE-DIMENSIONAL IMAGING DEVICE

A time of flight (ToF) sensor includes: a first pixel including a first photogate to receive light reflected by an object and generate a first phase signal, and a second photogate to generate a secondphase signal having a phase difference of 180 degrees with respect to the first phase signal; a second pixel including a third photogate to receive the reflected light and generate a third phase signal different from the first phase signal and a fourth photogate to generate a fourth phase signal having a phase difference of 180 degrees with respect to the third phase signal; a first signal outputunit to output the first and second phase signals; and a second signal output unit to output the third and fourth phase signals, wherein the first, second, third and fourth photogates output the first to fourth phase signals during a frame period. 一种飞行时间(ToF)传感器包括：第一像素，包括用于接收由物体反射的光并生成第一相位信号的第一光电门，和用于生成相对于第一相位信号具有180度相位差的第二相位信号的第二光电门；第二像素，包括用于接收反射后的光并生成与第一相位信号不同的第三相位信号的第三光电门，和用于生成相对于第三相位信号具有180度相位差的第四相位信号的第四光电门；第一信号输出单元，用
