A method of adjusting brightness of at least one region of an image being displayed on a display including a backlight comprising a set of individually controllable light sources configured to individually illuminate different regions of the display and a front modulator comprising an array of light valves, the method implemented in a processing device of the display and comprising: receiving an image signal; modulating, by the front modulator of the display, light emitted from the backlight to form an image based on the image signal; monitoring a power consumption of the display by evaluating the image signal representative of the image to be displayed to determine power information associated with the set of individually controllable light sources of the backlight; ramping down an amount of power provided to the backlight of the display and simultaneously increasing an amount of opening in the light valves of the front modulator such that a brightness of the display is not diminished, if the monitored power exceeds a maximum power threshold; wherein the ramping down an amount of power and simultaneous increasing an amount of opening is performed on a regional basis so that, in at least one region of the display, the ramping down and simultaneous increasing is performed relatively more than in at least another region of the display; wherein the ramping down and simultaneous increasing on a regional basis further comprises determining at least one region of interest based on the content of the received image signal, and applying more power to the light sources corresponding to the at least one region of interest and less power to the light sources corresponding to other regions of the display; wherein the at least one region of interest is determined by calculating variance in regional contrast, thereby distinguishing between in-focus subjects and background. receiving an image signal; modulating, by the front modulator of the display, light emitted from the backlight to form an image based on the image signal; monitoring a power consumption of the display by evaluating the image signal representative of the image to be displayed to determine power information associated with the set of individually controllable light sources of the backlight; ramping down an amount of power provided to the backlight of the display and simultaneously increasing an amount of opening in the light valves of the front modulator such that a brightness of the display is not diminished, if the monitored power exceeds a maximum power threshold; wherein the ramping down an amount of power and simultaneous increasing an amount of opening is performed on a regional basis so that, in at least one region of the display, the ramping down and simultaneous increasing is performed relatively more than in at least another region of the display; wherein the ramping down and simultaneous increasing on a regional basis further comprises determining at least one region of interest based on the content of the received image signal, and applying more power to the light sources corresponding to the at least one region of interest and less power to the light sources corresponding to other regions of the display; wherein the at least one region of interest is determined by calculating variance in regional contrast, thereby distinguishing between in-focus subjects and background.
