By way of example, a method includes receiving image data to be displayed on pixels of a display panel, generating a global histogram of the image data, generating a plurality of thresholds based on the global histogram, and defining a first threshold and a second threshold of the plurality of thresholds as local thresholds based on the global histogram and a local histogram. The first threshold and the second threshold are generated according to a local tone mapping function. The method further includes adjusting a luminance of one or more of pixels of the display panel based at least in part on the first threshold and the second threshold."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Devices and methods of adaptive dimming using local tone mapping","description":"Methods, systems, and devices for improving contrast, dynamic range, and power consumption of a backlight in a display are provided.
