Abstract
A signal processing apparatus according to an embodiment of the present technology includes an acceleration arithmetic unit. The acceleration arithmetic unit extracts, on a basis of a first detection signal and a second detection signal, the first detection signal including information related to an acceleration along at least a uniaxial direction and having an alternating-current waveform corresponding to the acceleration, the second detection signal including the information related to the acceleration and having an output waveform in which an alternating-current component corresponding to the acceleration is superimposed on a direct-current component, a dynamic acceleration component and a static acceleration component from the acceleration.
