Patent Images
1. A motion sensing apparatus comprising:
- a sensor configured to sense a motion of an object;
a variation determination unit configured to determine a variation in the sensed signal provided from the sensor;
an ODR control unit configured to control an output data rate (ODR) in proportion to a determination result at the variation determination unit; and
a digital signal output unit configured to read the signal provided from the sensor based on the ODR controlled by the ODR control unit, and output the same as a digital value.
