To provide a far infrared imaging system and a far infrared imaging method, which correct output values from a plurality of far infrared imaging apparatuses so that these output values are approximately the same for the same object.

The far infrared imaging system corrects an output value of each image sensor and acquires imaging data by using a plurality of far infrared imaging apparatuses having image sensors arrayed like a matrix and connected to each other so that output values can be communicated with each other, measures the surface temperature of an object and stores the ratio of an output value change to a temperature change in each image sensor. The far infrared imaging apparatus acquires the measured surface temperature, reads an output value corresponding to the acquired surface temperature in each image sensor, corrects the output value by using the ratio of the output value change to the temperature change which is stored in each image sensor, and outputs the corrected output value to the external.
