Claim 13:
14. A method comprising:
measuring a first luminance of a display when the display is presenting an image with a first encoded intensity and a first refresh rate;
measuring a second luminance of the display when the display is presenting the image with the first encoded intensity and a second refresh rate;
storing a difference between the first luminance and the second luminance;
measuring a third luminance of the display when the display is presenting the image with a second encoded intensity and the first refresh rate;
measuring a fourth luminance of the display when the display is presenting the image with the second encoded intensity and the second refresh rate; and
storing a difference between the third luminance and the fourth luminance; and
generating a lookup table, the lookup table associating:
the first encoded intensity with the difference between the first luminance and the second luminance; and
the second encoded intensity with the difference between the third luminance and the fourth luminance.
