PROBLEM TO BE SOLVED: To detect a temperature of an infrared emission source by adopting a visible light sensor used generally in a visible light camera.SOLUTION: In an infrared camera (smartphone) 100, RGB signals of a CMOS sensor 4 are converted to YCbCr signals, and then a ratio of first and second color differences Cb, Cr is computed. A map 14 is referred to on the basis of the ratio, and the temperature of an imaged infrared emission source is detected from the map 14. The temperature is corrected on the basis of a Y value as needed. |
