摘要
In the present specification, a method of measuring blood volume by a device including a camera, comprising: taking a skin image using the camera; Detecting a skin region from the captured image; Calculating an average value of color data for the skin area; Calculating a pulse wave signal by applying a low pass filter (LPF) to the average value of the color data; Detecting a primary peak point within a specific frequency range of the pulse wave signal and detecting the detected secondary peak point; And it characterized in that it comprises a step of measuring the blood volume (blood volume) state by using the slope and the body information calculated by using the interval between the peak points.
