| 摘要 |
The present invention relates to a device for detecting motions and a method for detecting motions and includes a change rate calculation unit for calculating a change rate of signals outputted from the sensor, a decision range determination unit for determining the decision range in proportion to the change rate calculated in the change rate calculation unit, a motion decision unit for deciding the existence and inexistence of the motions from the signals outputted in the sensor based on the decision ranged determined in the decision range determination unit and an output unit for outputting the decision result of the motion decision unit. |
