Claim One:
1. An apparatus for measuring calories consumed during sleep, comprising: input means, detection means, calculation means, determination means, coefficient calculation means, consumed calorie calculation means, and storage means, wherein the input means inputs the body information of a subject, the detection means detects body oscillations during sleep, the calculation means calculates consumed calories based on the body oscillations, the determination means determines whether each signal of body oscillation during sleep is a signal of breathing/heartbeat oscillation or a signal of body motion and determines the intensity of the body motion, the coefficient calculation means calculates a coefficient which is a reference value for calculating calories consumed during sleep, based on the signals in a given period of breathing/heartbeat oscillation and a sleep metabolic rate which is obtained based on the input body information, the consumed calorie calculation means calculates calories consumed during sleep, based on consumed calories according to the magnitude of the signal of breathing/heartbeat oscillation, consumed calories according to the magnitude of the signal of body motion of each intensity and the coefficient, the storage means stores at least thresholds for making determinations in the determination means, an arithmetic expression for calculating the coefficient and an arithmetic expression for calculating the calories consumed during sleep in advance.
