Abstract
Provided is an infrared imaging device capable of reducing streak noise by calculating correction coefficients for correcting streak noise from a single image. The infrared imaging device includes: a thermal image generator to generate a single thermal image on the basis of a signal from a thermal image sensor; a correction coefficient calculator to calculate multiple correction coefficients included in a correction equation for converting pixel values of pixels included in the single thermal image into target values in which streak noise is reduced; and a thermal image corrector to correct a thermal image generated by the thermal image generator by using the multiple correction coefficients, wherein the correction coefficient calculator calculates the multiple correction coefficients on the basis of difference between pixel values of pixels arranged in a direction in which the streak noise occurs in the single thermal image.
