<p>PURPOSE: To correct the offset and drift components of a vibration sensor by constituting the module so that the reference voltage of an amplifier for a shake detecting part may be varied based on vibration information fetched by a CPU. CONSTITUTION: The signal processing module is prepared for differentially amplifying an input signal with reference to a prescribed reference voltage and outputting the signal, and in the case of judging by the CPU 3 that the amplified output signal does not lie within a prescribed range, a control information signal is outputted to an information input part 10, a reference voltage value is shifted by a reference voltage generating part 5 based on the output signal, and then, the input signal is differentially amplified with reference to the level-shifted reference voltage by a differential amplifier part 4.</p> |
