INFRARED IMAGING APPARATUS

摘要

PROBLEM TO BE SOLVED: To provide an infrared imaging apparatus for simultaneously correcting a shading phenomenon and a dispersion of characteristics of a detecting element. SOLUTION: This infrared imaging apparatus is constituted of: an A/D converter 11 which converts an output of an infrared detector 10 into digital signals; a dividing circuit 14 in which an output of A/D converter 11 is converted into a housing component, and a ratio of the converted housing component to output level of all detecting element is calculated; a memory 15 which stores a difference of the output profile of the housing component and the output profile of the scene incident component; a memory 16 stores the output profile of the scene incident component; a multiplying circuit 17 which multiplies the ratio of the output level of the housing component by a memory value; an adding circuit 18 which adds a result of the multiplication to the value of connection data 2 memory 16; and a dividing circuit 19 which subtracts the output of the infrared detecting part depending on the results of the adding circuit 18.
