An image acquisition part (15) acquires image data from an image sensor (2, 3) provided in a room. A storage (6) stores information indicating a transition model of a human body posture and test information indicating a test area of the image data in each posture of the transition model. A posture estimator (5) calculates a statistic in the test area of the image data by referring to the information indicating the transition model and the test information, and estimates a current human body posture from a human body posture before one point of time based on the statistic.
