<p><P>PROBLEM TO BE SOLVED: To provide a calibration device that unifies variance among pixel values output from a plurality of image input devices. <P>SOLUTION: The calibration device 50 includes: a calculation unit 11 which allocates Target_Min, Target_Max as pixel values for dark light intensity and a sensor saturation pixel value of an image input device 100a, and calculates Target_Mid as a pixel value for bright light intensity of the image input device 100a on the basis of the dark light intensity sensor pixel value, the bright light intensity sensor pixel value, and the sensor saturation pixel value of the image input device 100a, and Target_Min, and Target_Max; and a mapping unit 13 which allocates Target_Min and Target_Mid as pixel values after calibration to the dark light intensity and bright light intensity. Accordingly, the calibration device 50 can unify the variance among pixel values output from image input devices 100a to 100c. <P>COPYRIGHT: (C)2010,JPO&INPIT</p> |
