A pulse wave detection device detects the face from a frame image and corrects the brightness of the face in accordance with the size of the face surface to appropriately detect a pulse wave even if brightness is changed due to movement of a subject with respect to lighting. The brightness of the face depends on the distance between the lighting and the face, and this is equal to indirect measurement of the distance from the lighting to the face using the size of the face. As described above, a pulse wave detecting device estimates/measures a pulse rate of the subject from a brightness signal after intensity of the brightness of the face photographed on the frame image is corrected using the size of the face, by using the correlation between the size of the face of the subject on the frame image and the brightness of the face.
