1. A method of operating a light detection and ranging (LiDAR) device, the method comprising:
obtaining receiving signals corresponding to reference laser pulses generated from a reference signal;
obtaining a main receiving signal having a maximum value among the receiving signals with respect to a time point;
correcting a value of a sub-receiving signal included in the receiving signals at the time point based on the maximum value of the main receiving signal; and
obtaining a time of flight (ToF) of a laser pulse corresponding to the sub-receiving signal based on a correlation between the corrected value of the sub-receiving signal and the reference signal,
wherein the correcting of the value of the sub-receiving signal comprises subtracting a value obtained by multiplying the maximum value by a correction factor, from the value of the sub-receiving signal at the time point.
