Title:
脈波検出装置および脈波検出プログラム
Document Type and Number:
Japanese Patent JP6765678
Kind Code:
B2
Abstract:
Provided is a pulse wave detection device and a pulse wave detection program that are capable of detecting a pulse wave by removing the influence of a color change of ambient light. A pulse wave detection device 1 is configured such that a correction parameter value for correcting a value of a strong area value memory 7e for detecting a pulse wave signal is calculated through multiplication of the ratio of the value of the strong area value memory 7e and a value of a weak area value memory 7f by a value based on the weak area value memory 7f, and the value of the strong area value memory 7e is corrected on the basis of the correction parameter value. Thus, a pulse wave can be detected by removing, from the value of the strong area value memory 7e, an external disturbance caused by a color change of ambient light without needing a background for correcting the color change of the ambient light. In addition, since the correction parameter value with respect to the value of the strong area value memory 7e is calculated by a simple calculation method, the value of the strong area value memory 7e can be corrected within a short period of time, and the response of the pulse wave detection device 1 can be improved.
