摘要： An apparatus for estimating bio-information, the apparatus including a pulse wave sensor and a processor. The pulse wave sensor includes a plurality of channels, each channel of the plurality of channels being configured to measure a first pulse wave signal of a first wavelength and a second pulse wave signal of a second wavelength that is different from the first wavelength. The processor is configured to: for each channel of the plurality of channels, generate a first oscillogram based on the first pulse wave signal, generate a second oscillogram based on the second pulse wave signal, and convert a phase delay between the first oscillogram and the second oscillogram into an area. The processor is further configured to determine a channel among the plurality of channels based on the area of each channel, and estimate bio-information based on the determined channel.
