Claim 0:
1. An apparatus for non-invasively detecting a body component, while minimizing an effect of local blood pressure, the apparatus comprising:
a sensor configured to detect a bio-signal of an object according to a contact pressure that gradually changes between the object and the sensor; and
a processor configured to determine 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 to detect a body component of the object based on the determined time point,
wherein the processor is further configured to perform filtering on the bio-signal to remove noise in the contact pressure, and differentiate the filtered bio-signal, and
wherein the processor is further configured to detect 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 determining the time point, remove an amplitude value of the filtered bio-signal at the detected point.
