Abstract: A strain amount calculation system includes an imaging unit, and a strain amount calculation device that acquires an image taken by the imaging unit, measures luminescent brightness from the acquired image, calculates an amount of strain on the object caused by a load on the object, based on a temporal change in the measured luminescent brightness, and outputs information on the calculated strain amount.
