Abstract: A method of operating a light detection and ranging (LiDAR) device includes 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.
