Described are a method and apparatus for measuring a psychophysiological parameter of a target in a reliable and accurate way. The measuring method comprises the following steps: acquiring a psychophysiological video of a target through a video; measuring a vibration parameter of the target from the video; creating a biological signal image based on the vibration parameter; and processing the biological signal image and creating a psychophysiological reaction parameter of the target. 대상의 정신생리학적 매개변수를 신뢰할 수 있고 정확하게 측정하는 방법 및 장치에 관해 기술된다. 측정 방법은 동영상을 통해 피험자의 정신생리학적인 피험자로부터 동영상을 획득하는 단계, 상기 동영상으로부터 피험자의 진동 파라미터를 측정하는 단계, 상기 진동 파라미터에 기초하여 생체신호 이미지를 생성하는 단계, 그리고 상기 생체신호 이미지를 처리하여 피험자의 정신생리학적인 반응 매개변수를 생성하는 단계를 포함한다.
