PURPOSE:To obtain a thermograph device proper to the diagnosis of neurology by finding the average temperature of each area on the basis of the temperature data of picture elements included in plural areas regulated by frames and then finding and displaying the difference of average temperatures of respective areas. CONSTITUTION:A frame setting circuit 24A is operated to arrange a required frame A in a temperature distribution image Z. At that time, the circuit 24A generates positional data for determining the frame and a frame writing circuit 23 writes a frame pattern in a memory 17. Consequently, the frame A is displayed together with the temperature distribution image on a screen of a display device 11. When the frame A is set up, an intra-frame address setting circuit 25 lists up n picture elements in the frame A, reads out the temperature data of the picture elements from a picture memory 8, finds out an average temperature Ta in an average temperature arithmetic circuit 26, and stores the average temperature Ta in a register 27A. The same processing is applied also to frames B-D. Subtraction circuits 28-31 operate the difference of the average temperatures between the frames. Thus, the difference of the average temperatures between respective frames is displayed on the screen of the device 11. |
