Claim 12:
13. A method of non-invasively detecting a body component, while minimizing an effect of local blood pressure, the method comprising:
detecting a bio-signal from an object based on a contact pressure that gradually changes between the object and a sensor part;
determining a time point at which an amplitude of an alternating current (AC) component of the bio-signal is maximum or a slope of a direct current (DC) component of the bio-signal is maximum; and
detecting a body component based on the determined time point,
wherein the determining the time point comprises:
performing filtering on the bio-signal to remove noise in the contact pressure;
differentiating the filtered bio-signal, and detecting a point having a value greater than a first predetermined threshold value, or a point having a value equal to or less than a second predetermined threshold, from the differentiated bio-signal; and
prior to the determining the time point, removing an amplitude value of the filtered bio-signal at the detected point.
