Abstract
A respiration information estimation device includes a specific region setting unit that sets a specific region and a motion vector calculation point as a point as a reference of a motion vector based on an image including an upper body of an object person, a motion vector calculation unit that calculates the motion vector from a movement amount of the motion vector calculation point in each of the images captured consecutively, a respiration reference axis calculation unit that calculates a respiration reference axis from a respiration central point and the motion vector calculation point, a respiration signal calculation unit that calculates a respiration signal from a component of the motion vector in a direction of the respiration reference axis, and a respiration information calculation unit that calculates a respiration information estimation result, as a result of estimating a body motion caused by the respiration, from the respiration signal.
