  • Patent number: 10720112
    Abstract: The present disclosure provides method and device for dimming the backlight of an LCD. A number of pixels at each grayscale level of an input image is determined. The determined number of pixels at each grayscale level is accumulated to generate an accumulated distribution of the number of pixel and the accumulated distribution is filtered. A threshold grayscale level at which the filtered accumulated distribution exceeds a threshold value is determined. A scaling factor is determined based on the threshold grayscale level. The grayscale level of pixels of the input image having a grayscale level lower than or equal to the threshold grayscale level are up-scaled based on the scaling factor, the grayscale value of pixels of the input image having a grayscale level greater than the threshold grayscale level are set to have a predetermined clipping grayscale level, and the LCD backlight is dimmed based on the scaling factor.
