Patent ID: 8786585

Claim:
A method of adjusting a display device according to a display environment, comprising: sensing the display environment of the display device; wherein sensing the display environment comprises sensing the display environment with a first sensor and a second sensor; generating environment data that corresponds to the display environment, wherein the environment data includes color data; wherein the color data comprises first color data and second color data corresponding to the first sensor and the second sensor respectively; adjusting a color appearance model according to the color data; wherein adjusting the color appearance model according to the color data comprises: adjusting the color appearance model according to the first color data and the second color data as a function of distance to the first sensor and to the second sensor; generating a control signal according to the color appearance model having been adjusted; controlling a backlight of the display device according to the control signal; and storing user white point data that differs from reference white point data, wherein the color appearance model is configured to receive reference environment data and the user white point data, and wherein the adjusted color appearance model is configured to generate a target white point data that corresponds to the control signal, further comprising: scaling a front modulator according to the target white point when the target white point exceeds a threshold; and scaling the front modulator according to the threshold when the target white point does not exceed the threshold.
