摘要

A respiration monitoring apparatus includes an image acquiring section that acquires an image of an imaging target region including a physical part of a subject that reciprocates in response to the respiration of the subject as picked up with inclination of a predetermined angle relative to the reciprocating direction at each predetermined timing, a displacement computing section that computationally determines the displacement of the position of the imaging target region between the first clock time that is an arbitrarily selected timing and the second clock time that is the timing of a predetermined number of counts as counted from the first clock time on the basis of the difference between the luminance of each of the pixels on the image acquired at the first clock time and the luminance of the corresponding pixel on the image acquired at the second clock time, and a position determining section that determines the position obtained by adding the displacement of the position of the imaging target region between the first clock time and the second clock time as computationally determined by the displacement computing section to the position of the imaging target region at the first clock time as the position of the imaging target region at the second clock time.
