Abstract

In this paper, we propose a method to remove the influence of light on the face from display in imaging photoplethysmography (iPPG) to measure blood flow of the face when watching a video with an RGB camera. We propose a simple method which is used to correct the pixel values of the face by the pixel values of a standard white plate. The proposed method is evaluated by simulation and actual measurement. As a result, it is shown that it is possible to reduce the influence of light on the face from display in iPPG and measure variation in blood flow of face when watching a video.
