An observation method includes: displaying video of a subject; receiving designation of at least one point in the video; determining an area or edge in the video based on the point; setting, in the video, observation point candidates in the area or on the edge; evaluating an image of each observation block candidate having a center point that is a corresponding observation point candidate, eliminating any observation point candidates not satisfying conditions, and setting remaining observation point candidates to a plurality of observation points; and observing a movement of the subject itself applied with an certain external load at each observation point. The conditions are that (i) the subject is in a corresponding observation block candidate, (ii) image quality of the observation block candidate is good without temporal deformation or blur, (iii) a displacement of the observation block candidate is not greater than that of any other observation block candidates.
