<P>PROBLEM TO BE SOLVED: To provide an infrared imaging device that can remove drifts caused by variations over time and variations in ambient temperature to arise in infrared detecting elements and in signal processing, output stable digital data and can be easily used without requiring any specific know-how. <P>SOLUTION: In an infrared imaging device, against noise arising from temperature drifts in signal processing systems operating in parallel, a built-in CPU 101 reads in outputs from insensitive elements 102 and 104 to process arithmetic operation and figure out correction data, and corrects outputs from infrared detecting elements thereby to supply noise-cleared digital outputs and accordingly to permit easy use without requiring any specific know-how. <P>COPYRIGHT: (C)2013,JPO&INPIT |
