Non-contact detection refers to the use of external energy without contacting the human body to detect changes of the human body in the physiological environment. Physiological monitor instrument is generally connecting the human body by using wired sensor to measure human body’s physical parameters; it is uncomfortable for people to using this monitoring instrument for a long time. Non-contact detection devices are not suitable for use in general household or personal, because its price is too expensive and difficult to acquire. This study proposes a non-contact method based on video format to measure the heartbeat. It uses the information of the absorption amount of our face to various lights to predict the heartbeat; it is also through image processing and Independent Components Analysis (ICA) to find the hidden information in images and to integrate these information, and then through frequency domain transformation and heartbeat estimation procedure, to achieve a complete automatic non-contact measurement.
