CALIBRATION DEVICE, CALIBRATION METHOD, CALIBRATION PROGRAM, COMPUTER-READABLE RECORDING MEDIUM, SENSOR AND DISPLAY DEVICE

PROBLEM TO BE SOLVED: To achieve a calibration device capable of acquiring the same results of calibration for all optical sensor elements even if a brightness reference image cannot be obtained under the same conditions. SOLUTION: The calibration device 50 includes: an output value setting means 11 for output of a first dark output value for a first dark illuminance as illuminance under darkroom conditions and a first bright output value for an arbitrary first illuminance included in an illuminance area from a saturation illuminance to the first illuminance, respectively, as output values after calibration of image data captured by optical sensor elements; and a correction function setting means 12 for setting a straight line connecting a first dark output point and a first bright output point as a correction function for performing calibration for correcting the variations of an output value from the optical sensor elements in the illuminance area from the first illuminance to the saturation illuminance.
