1. A temperature estimation device comprising:
an acquiring section that acquires a photographed image photographed by a photographing section including an infrared light sensor and a housing;
a generating section that corrects the photographed image with use of a correction parameter and a temporarily set temperature of the housing to generate a corrected image of the photographed image, the correction parameter that is calculated by prior temperature calibration with respect to the photographing section; and
an estimating section that estimates a temperature of the housing on a basis of non-uniformity of luminance values of pixels included in the corrected image.
