Abstract
A plurality of thermal images of an observed object at different times are simultaneously displayed on a single screen of a television monitor simply and economically. The thermal imaging apparatus includes an infrared camera to scan the observed object and to produce a detected video output, a TV monitor to display the thermal images, and a hard memory to convert the IR camera scan to the TV monitor display. The capacity of the hard memory is kept at a minimum which is sufficient for memorizing image data of one frame of scanning. For simultaneously display of plural images, the IR camera scans so that the observed object is in a limited part of the field of view, to produce a detected video output with limited video signals corresponding to the limited part of the field of view, and the hard memory writes the limited signals in a limited part of the hard memory corresponding to the limited part of the field of view, as limited image data, at the scan speed of the IR camera, so that the limited image data taken at each respective time is memorized in the hard memory. All the image data memorized in the hard memory are then read out at the TV displaying speed and simultaneously displayed on the TV monitor screen.
