Bio-information estimation apparatus and bio-information estimation method

A bio-information estimation method, comprising:

• simultaneously measuring a spectrum of light reflected from an object, and measuring a temperature of the object;
• calculating a spectrum correction factor, comprising at least one of a correction factor of a gain, a correction factor of a constant, and a correction factor of a slope, based on the measured temperature of the object;
• and
• adjusting the measured spectrum based on the calculated correction factor.

A bio-information estimation apparatus, comprising:

• a spectrum measurer configured to measure a spectrum of light reflected from an object;
• a temperature measurer configured to measure a temperature of the object while the spectrum measurer measures the spectrum;
• and
• a processor configured to calculate a spectrum correction factor, comprising at least one of a correction factor of a gain, a correction factor of a constant, and a correction factor of a slope, based on the measured temperature of the object, to adjust one of the measured spectrum and a reference spectrum based on the calculated correction factor, and to estimate the bio-information based on the adjusted spectrum and an uncorrected one of the measured spectrum and the reference spectrum.
