Claim 14:
15. The method of claim 14, wherein adjusting the luminance of the image data by applying the local scaling factor includes:
determining the local scaling factor as a first constant and applying the first constant to the image data for the unit area corresponding to the first image load when the second image load is higher than a preset maximum value,
determining the local scaling factor as a second constant smaller than the first constant, and applying the second constant to the image data for the unit area corresponding to the first image load when the second image load is lower than a preset minimum value, and
determining the local scaling factor as a value between the first constant and the second constant, and applying the second constant to the image data for the unit area corresponding to the first image load when the second image load is between the preset minimum value and the preset maximum value.
