<p>PURPOSE: To remove the offset and drift components of a vibrating gyroscope by differentially amplifying the shift output of a reference voltage shifting means and an input signal. CONSTITUTION: Two positive and negative input parts are installed in an amplifier part 2, a signal VIN corresponding to the shake state of a camera is inputted to one input part, and a prescribed voltage corresponding to the output state of the amplifier 2 is inputted to the other input part. A voltage difference between two input parts is amplified with a prescribed amplification degree, and then, outputted to the outside as a signal VOUT1 so as to be used as camera shake information. In the case of judging by an amplified output judging part 3 that the output of the amplifier part 2 is over the prescribed extent, or below the prescribed extent, the information presenting the effect is transmitted to a state storing part 4 and the information on the output state of the amplifier part 2 is stored in the storing part 4. A prescribed voltage is generated by a reference voltage generating part 5 based on the information stored by the state storing part 4, and then, it is transmitted to the one input part of the amplifier part 2 and also, outputted to the outside as the output of the amplifier part 2 and as a signal VOUT2.</p> |
