Abstract: In a control system, an image data acquisition unit acquires thermal image data from an infrared sensor. A statistical data generation unit generates statistical data about pixel values from the thermal image data. A calibration control unit controls, based on an environmental temperature, calibration for a 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. An image data output unit outputs image data related to the thermal image resulting from the calibration. 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 controls the calibration to be performed for an adjustment value which results from shift adjustment based on a shift amount set in advance.

Abstract: In an image processing apparatus, a first correction unit corrects imaging data acquired from an infrared imaging device, based on a first correction table, and outputs first corrected data. A second correction unit generates a second correction table for the imaging data in a state in which a shutter is closed, and outputs second corrected data based on the second correction table. A saturated region detection unit detects a saturated region in the imaging data. A shutter control unit performs closing control for the shutter, based on a result of detection of the saturated region. An abnormal pixel detection unit detects whether or not the imaging data acquired in the state in which the shutter is closed includes an abnormal pixel. A selection unit selects and outputs either the first corrected data or the second corrected data in accordance with a result of detection by the abnormal pixel detection unit.
