ABSTRACT:
A thermal image analysis system 1 includes a reference signal generating circuit 10 for generating two or more reference signals, an image synthesizing circuit 11 for combining an image outputted from an image output circuit 9 with the reference signals, a reference signal sensing circuit 13 for sensing the reference signals from an image signal inputted into an image input circuit 8, a numerical input circuit 12 for inputting temperature information corresponding to the reference signals and a compensation circuit 14 for compensating the image signal, based on the temperature information and reference signals. The reference signal generating circuit 10 generates reference signals of two or more levels. The reference signal sensing circuit 13 senses the reference signals from an image signal reproduced by an image recording/reproducing system 2. The compensation circuit 14 compensates the reproduced image signal to the state similar to that of the image signal before being recorded, based on the temperature information inputted from the numerical input circuit 12. Such a thermal image analysis system 1 can compensate the image signal degraded or changed through the image recording/reproducing system 2 to improve the accuracy in thermal image analysis.
