Claim 15:
16. 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;
determining that a difference between the first luminance and the second luminance exceeds a threshold;
storing the difference between the first luminance and the second luminance, wherein the storing the difference between the first luminance and the second luminance comprises storing the difference between the first luminance and the second luminance based on determining that the difference between the first luminance and the second luminance exceeds the threshold;
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;
determining that a difference between the third luminance and the fourth luminance is less than the threshold; 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 a zero or null value.
