Claim 9:
10. A method for adjusting a gradation value comprising:
determining a position of an input image whether the input image is an image corresponding to a first display area or a second display area having a resolution less than that of the first display area and outputting an area value that indicates the position of the input image;
outputting a first gradation value corresponding to a brightness of the input image according to the area value;
outputting a corrected gradation value corresponding to the first gradation value; and
displaying a corrected image having a corrected brightness corresponding to the corrected gradation value,
wherein the brightness of the input image is a first display brightness when the input image is an image corresponding to the first display area and the brightness of the input image is a second display brightness when the input image is an image corresponding to the second display area,
wherein the first display brightness is smaller than the second display brightness for the same gradation, and
wherein a light transmittance of the first display area is smaller than that of the second display area.
