摘要： An action analysis method comprising: an image recording step for continuously photographing a target; a movement locus measuring step for obtaining a movement locus of the target; an action analysis step for analyzing an action of the target from the movement locus; and an output step. In the action analysis step, a speed v and a movement direction displacement angle θ for each unit time is obtained from the movement locus; an average value X of v·cos θ for each unit time within a predetermined time is obtained; and a predetermined extraction target is distinguished by a statistic measure using the average value as an operation element index.
