ABSTRACT:
In the present thermographic camera, an object is scanned by a horizontal and vertical scanning mechanisms in order to obtain temperature signals of each point on the object, and the temperature distribution of the object is indicated on a scanning display device, such as a cathode ray tube, on the basis of the signals obtained by the scanning. Temperature information of one or more arbitrary points on the object are sampled from each frame, and temperature variation of a point on the object is measured, while the identity of the point or points is marked on the temperature distribution display.
