1. A light detection and ranging (LiDAR) device comprising:
a light emitter configured to emit light onto an object, the light being modulated based on a width modulation signal before being emitted to the object;
a light receiver configured to receive the light reflected by the object and generate a first reception signal based on the received light; and
a processor comprising a time-to-digital converter (TDC) configured to measure a time delay based on the first reception signal, in response to a pulse width of the received light corresponding to pulse width information included in the width modulation signal, wherein the processor is configured to calculate a distance to the object based on the time delay measured by the TDC.
