The invention provides a system and method for calculating a backlight level for an image being displayed on an electronic device. The system comprises: a backlight adjustment module to calculate an intensity value of an image for display on the electronic device; a display for displaying the image; and a backlight system to provide a backlight for the display. The backlight system is responsive to control signals generated by the backlight adjustment module. In the system, the intensity value represents an average intensity of the image.
