Abstract
A thermal image acquisitor () is attached to a wall () or a ceiling () on a side of a head of a care recipient () in a case where the care recipient lies on a bed (), and captures an image of the bed and its surroundings from diagonally above to acquire a thermal image. Reference setting circuitry () sets two reference lines () respectively corresponding to a left end and a right end of the bed in the thermal image, and a reference height () for determining sitting-up of the care recipient. Heat source detection circuitry () detects a mass () of a heat source in the thermal image. State determination circuitry () determines a state of the care recipient from a positional relationship between a safe area () enclosed with the reference lines and the reference height and the mass of the heat source.
