APPARATUS AND METHOD FOR ESTIMATING BIO-INFORMATION
FIG2 is a block diagram illustrating a bio-information estimating apparatus according to another embodiment
FIG2 is a block diagram illustrating a bio-information estimating apparatus according to another exemplary embodiment. Referring to FIG2, the bio-information estimating apparatus 200 includes a processor 120, a communicator 210, an output part 220, and a storage part 230. Although a sensor for measuring a bio-signal is not illustrated in FIG2, the bio-information estimating apparatus 200 may include the sensor depending on an embodiment. In this case, under the control of the processor 120 or at the request of the external device 250, the bio-information estimating apparatus 200 may selective obtain a bio-signal. For example, the bio-information estimation apparatus 200 may obtain a bio-signal by receiving a bio-signal from the external device 250 or by directly driving the sensor.

['1. An apparatus for estimating bio-information, the apparatus comprising: a sensor configured to measure a bio-signal; and a processor configured to obtain one or more characteristic points, related to one or more pulse waveform components constituting the bio-signal, based on a differential signal of the bio-signal, and to estimate bio-information based on the obtained one or more characteristic points.', '6. 6. The apparatus of one of claims 1 to 5, wherein the processor is configured to extract a feature by combining one or more of the obtained one or more characteristic points related to the one or more pulse waveform components, and estimate the bio-information based on the extracted feature, or wherein the sensor comprises a light source configured to emit light onto an object; and a detector configured to detect light scattered from the object, or wherein the bio-information comprises at least one of blood pressure, vascular age, arterial stiffness, aortic pressure waveform, stress index, and degree of fatigue, or further comprising an output part configured to output a processing result of the processor.', '15. A computer-readable medium having instructions that, when performed by a processor, cause the processor to perform the steps of: receiving, by a communicator, a bio-signal from an external device; and causing the processor to obtain one or more characteristic points, related to one or more pulse waveform components constituting the bio-signal, based on a differential signal of the  received bio-signal, and to estimate bio-information based on the obtained one or more characteristic points.']
