Abstract

A biosignal processing apparatus and a biosignal processing method are provided. The biosignal processing method includes: detecting a biosignal of a subject; detecting status information; and determining a correlation between the biosignal and the status information.

Claims

1. A biosignal processing method comprising:

detecting a biosignal of a subject;

detecting status information that influences the biosignal; and

determining a correlation between the biosignal and the status information.

2. The biosignal processing method of claim 1, wherein the determining comprising determining the correlation between the biosignal and the status information in response to the status information having a probability of influencing the biosignal of the subject.

3. The biosignal processing method of claim 2, wherein the determining further comprise determining that the status information has the probability of influencing the biosignal on a lookup table indicating that the status information corresponds to the detected biosignal.

4. The biosignal processing method of claim 1, wherein the biosignal of the subject is detected in a non-invasive manner.

5. The biosignal processing method of claim 1, wherein the biosignal includes at least one of information about an amount of a material contained in the subject and information about a motion of the subject.

6. The biosignal processing method of claim 1, wherein the biosignal includes information about at least one of blood sugar, cholesterol, body fat, blood pressure, an electrocardiogram, ballistocardiography, photoplethysmography, and an electromyogram of the subject.

7. The biosignal processing method of claim 1, wherein the status information is variable according to an external environment.

8. The biosignal processing method of claim 1, wherein the status information includes at least one of a temperature of an external environment, a humidity of the external environment, an atmospheric pressure of the external environment, a body water of the subject, a body temperature of the subject, and a motion of the subject.

9. The biosignal processing method of claim 1, wherein the correlation represents a degree of a change in the biosignal according to a change in the status information.

10. The biosignal processing method of claim 1, wherein the correlation represents a range of the status information corresponding to a reference range of the biosignal.

11. The biosignal processing method of claim 1, wherein the determining comprises:

generating a biosignal pattern based on the biosignal in time domain;

generating a status information pattern based on the status information in the time domain; and

determining a correlation value between the biosignal pattern and the status information pattern.

12. The biosignal processing method of claim 11, further comprising correcting the biosignal pattern based on the status information pattern.

13. The biosignal processing method of claim 1, further comprising displaying at least one of the status information, the biosignal, and the correlation.

14. A biosignal processing apparatus comprising:

a first sensor configured to detect a biosignal of a subject;

a second sensor configured to detect status information that influences the biosignal; and

a processor configured to determine a correlation between the biosignal and the status information.

15. The biosignal processing apparatus of claim 14, wherein the processor is further configure to determine the correlation in response to the status information being determined as having a probability of influencing the biosignal.

16. The biosignal processing apparatus of claim 14, further comprising a controller configured to control the first sensor based on the status information and the correlation.

17. The biosignal processing apparatus of claim 16, wherein the controller is further configured to activate the first sensor to detect the biosignal in response to the status information being in a reference range.

18. The biosignal processing apparatus of claim 17, wherein the reference range corresponds to an abnormal range of the biosignal.

19. The biosignal processing apparatus of claim 14, wherein the first sensor detects the biosignal of the subject in a non-invasive manner.

20. The biosignal processing apparatus of claim 14, wherein the biosignal includes at least one of information of an amount of a material contained in the subject and status information of an object contained in the subject.

21. The biosignal processing apparatus of claim 14, wherein the biosignal includes information about at least one of blood sugar, cholesterol, and body fat, blood pressure, an electrocardiogram, ballistocardiography, photoplethysmography, and an electromyogram of the subject.

22. The biosignal processing apparatus of claim 14, wherein the status information varies according to an external environment.

23. The biosignal processing apparatus of claim 14, further comprising a display configured to display at least one of the status information, the biosignal, and the correlation.

24. The biosignal processing apparatus of claim 14, further comprising a memory configured to store a lookup table indicating that the status information corresponds to the detected biosignal, wherein the processor is further configured to determine the correlation in response the biosignal being indicated as corresponding to the status information in the lookup table.
