1. A signal processing method comprising:
- receiving a signal obtained from an object as an input signal;
generating a time lag signal from the input signal;
calculating a difference between the input signal and the time lag signal; and
detecting the generation of the difference so as to feature a portion of the object at a position where the difference is generated.
