Claim 21:
22. A method comprising:
determining, by a computing device in response to a change in a refresh rate of a display, an encoded intensity of at least a portion of an image presented by the display;
determining that the encoded intensity is within a predetermined range; and
based on determining that the encoded intensity is within the predetermined range, adjusting an intensity of a signal for the portion of the image, wherein the adjusting the intensity of the signal for the portion of the image is based on an adjustment value retrieved from a lookup table using the encoded intensity, the lookup table associating:
a first encoded intensity with a difference between:
(i) a first luminance produced when an image is presented using the first encoded intensity and a first refresh rate, and
(ii) a second luminance produced when the image is presented using the first encoded intensity and a second refresh rate, as a result of a difference between the first luminance and the second luminance being above a threshold; and

a second encoded intensity with a zero or null value, as a result of a difference between (iii) a third luminance produced when the image is presented using the second encoded intensity and the first refresh rate, and (iv) a fourth luminance produced when the image is presented using the second encoded intensity and the second refresh rate, being below the threshold.
