Repeated sudden blood pressure changes in daily life are reported to raise the risk of cerebrovascular diseases in people even if they are not hypertensive patients. This syndrome is difficult to detect in usual medical examinations. Our research group is developing a contact-less measurement method for monitoring blood pressure changes using the video image of the human body, which is called a video plethysmography. This technique enables us to monitor blood pressure easily and constantly in a normal living environment. In our previous study, we showed that the pulse transit time calculated from the video plethysmography recorded in two different body areas reflected blood pressure changes. In this study, we show the possibility of estimating blood pressure changes based on the waveform of the video plethysmography recorded only in one body area.
