Title:
画像解析装置および生体情報生成システム
Document Type and Number:
Japanese Patent JP6716712
Kind Code:
B2
Abstract:
Pulse waves of a living body are detected with high accuracy. A pulse wave detection device includes a camera configured to capture an image of the living body a plurality of times through a first green filter and an infrared light filter having light transmission characteristics in a near-infrared light wavelength range within a wavelength range where a light absorption coefficient of oxidized hemoglobin is greater than a light absorption coefficient of reduced hemoglobin, and an image analysis unit configured to analyze a plurality of images of the living body captured by the camera and to detect the pulse waves of the living body. The image analysis unit is configured to detect the pulse waves by detecting a change in intensity of light in the near-infrared light wavelength range indicated by the plurality of images.
