<p>PURPOSE: To obtain a vibration detector capable of preventing the deterioration of a shake prevention effect due to the amplification of a high frequency area/a high frequency noise of a prediction calculation by providing a vibration information detecting means, a vibration transition predicting means and a predicted output judging means. CONSTITUTION: The device is constituted of a vibration detecting part 1 for detecting the vibration information, a vibration signal predicting part 2 where a vibration signal detected by the detecting part 1 is inputted and a prediction signal output judging part 3, between which and the predicting part 2, the signal is supplied. In this case, the transition of the detected vibration signal in the near future is predicted by the predicting part 2 when the vibration information is detected by the detecting part 1. In the case the results of the prediction operation satisfy a prescribed condition, the predicting part 2 is permitted by the judging part 3 to output the prediction signal, then, the predictive vibration signal is outputted by the predicting part 2. Thus, in the case a large noise occurs, the shake preventing effect due to the amplification of the high frequency area/the high frequency noise of the prediction operation is not deteriorated even in the case of not using the predicted value but a high-order expression.</p> |
