Title:
INFRARED IMAGING DEVICE AND INFRARED IMAGING PROGRAM
Document Type and Number:
WIPO Patent Application WO/2020/161867
Kind Code:
A1
Abstract:
Provided is an infrared imaging device capable of reducing streak noise by calculating a correction coefficient for correcting streak noise from a single image. This infrared imaging device comprises: a thermal image generation unit that generates a single thermal image on the basis of a signal from a thermal image sensor; a correction coefficient calculation unit that calculates a plurality of correction coefficients included in a correction equation for converting the pixel value of pixels included in the single thermal image into a target value in which streak noise is suppressed; and a thermal image correction unit that corrects the thermal image generated by the thermal image generation unit by using the plurality of correction coefficients. The correction coefficient calculation unit calculates the plurality of correction coefficients on the basis of the difference in pixel value of pixels arranged in the direction in which streak noise occurs in the single thermal image.
