Calorie consumption calculating apparatus and method using the three-axis acceleration sensor

The present invention calculates the calorie consumption by using the three-dimensional acceleration sensor device, and relates to its method, and more particularly, the calorie consumption by using the three-axis acceleration sensor that can be used to calculate the energy consumption (Kcal) with high precision according to the physical action of the person output to an apparatus and a method thereof. The inventors configuration means that make the calorie consumption calculating device using a three-axis acceleration sensor is three-axis acceleration sensor, the acceleration for each axis for outputting the acceleration signal for the x-axis, y-axis and z-axis, depending on the physical behavior of the user passing the low-band to perform a low-pass filtering on the output signal of the sensor filter unit, the low-pass high-pass digital filtering unit and performing a band pass digital filter with respect to the output signal from the filtered acceleration sensor by the unit filter , in which the using the output signal of the filtered acceleration sensor by the unit bandpass digital filter is characterized in that made in comprising a calculating calorie consumption for calculating the user's calorie consumption.
