Claim 8:
9. A method of estimating bio-information, the method comprising:
obtaining a bio-signal from an object;
obtaining function values by applying a predetermined function to sections of the bio-signal, corresponding to respective windows of a predetermined size, while sliding a window on a time axis of the bio-signal, wherein the predetermined function comprises a function for obtaining a sum of absolute (ABS) value of amplitude values of a section of the bio-signal corresponding to a respective window, the ABS value including a first ABS value of amplitude values greater than a reference amplitude value and a second ABS value of amplitudes values lower than the reference amplitude value, among the amplitude values of the section of the bio-signal;
applying a preprocessing function to the first ABS value and the second ABS value of each section of the sections of the bio-signal, and obtaining an equalized oscillometric waveform envelope by combining the preprocessed first ABS value and the preprocessed second ABS value for each section of the sections of the bio-signal; and
estimating bio-information of the object based on the equalized oscillometric waveform envelope.
