1. A control system comprising:
an image data acquisition unit which acquires thermal image data including a sensor output value related to a thermal image from an infrared sensor for capturing the thermal image;
a statistical data generation unit which generates statistical data about pixel values related to the sensor output value from the thermal image data;
a calibration control unit which controls, based on an environmental temperature, calibration for the sensor output value of the thermal image data in a state where a shutter is closed, the shutter blocking light incident on the infrared sensor; and
an image data output unit which outputs image data related to the thermal image resulting from the calibration,
wherein in a case where the pixel values included in the statistical data include an upper limit value or a lower limit value, the upper limit value or the lower limit value being set in advance, the calibration control unit performs shift adjustment for the sensor output value by a shift amount, which is set in advance, and controls the calibration to be performed for an adjustment value resulting from the shift adjustment.
