  • System and method for adjusting an intensity value and a backlight level for a display of an electronic device
    Patent number: 8194028
    Abstract: The disclosure relates to a system and method for determining pixel intensity values (luma values) for an image being displayed on a display of an electronic device, then adjusting the pixel intensity and the backlight level for the image that is output to a liquid crystal display (LCD). The system comprises: a display for displaying an image to be displayed on the device; an image adjustment module to identify the pixel intensity values of the image, to determine new pixel intensity values for the image based in part on the original pixel intensity values, to provide the (adjusted) image at the new pixel intensity values to the display and to determine a backlight level for the image at the new pixel intensity values. The system further comprises a backlight system to provide a backlight for the adjusted image at the adjusted backlight level.
