1. An image processing apparatus comprising:
a first correction unit configured to correct imaging data acquired from an infrared imaging device that captures a thermal image outside of a mobile body, based on a preset first correction table, and output first corrected data having been corrected;
a second correction unit configured to generate a second correction table for the imaging data in a state in which a shutter is closed, and output second corrected data having been corrected based on the generated second correction table;
a saturated region detection unit configured to detect that a saturated region is present in the imaging data;
a shutter control unit configured to perform closing control for the shutter for protecting the infrared imaging device based on a result of detection of the saturated region;
an abnormal pixel detection unit configured to detect whether or not the imaging data acquired in the state in which the shutter is closed includes an abnormal pixel that is included in the first corrected data and pertains to a pixel having a luminance value exceeding a preset threshold; and
a selection unit configured to select and output either the first corrected data or the second corrected data in accordance with a result of detection by the abnormal pixel detection unit.
