Abstract
A lidar noise removal apparatus outputs an electrical signal corresponding to an input light signal and compares the electrical signal with a threshold voltage to detect an electrical signal greater than the threshold voltage. The apparatus variably adjusts the threshold voltage based on a result of comparing the number of receptions of the electrical signal detected through the comparative device with a preset first reference number of times.
