Abstract
An adjustment method includes acquiring a first captured image obtained by imaging of a range containing a first whole image and a target image, acquiring a fourth gradation value obtained by correction of a gradation value of a fourth unit image based on a gradation value of a first unit image and a gradation value of a second unit image in the first captured image, acquiring a fifth gradation value obtained by correction of a gradation value of a fifth unit image based on the gradation value of the first unit image and a gradation value of a third unit image in the first captured image, calculating a first gradation value difference as a difference between a gradation value of the target image and the fourth gradation value, calculating a second gradation value difference as a difference between the gradation value of the target image and the fifth gradation value, and correcting a displayed image using a first correction value when the first gradation value difference is equal to or larger than the second gradation value difference.
