Abstract
Various methods and systems are provided for increasing an efficiency of operations for improving digital image quality. In an embodiment, a method for processing a digital image includes generating a higher resolution histogram from the digital image, the higher resolution histogram generated from a lower resolution histogram of raw image data of the digital image, filtering the higher resolution histogram, downsampling the filtered, higher resolution histogram to form a downsampled histogram, generating one or more picture quality adjustments based on the downsampled histogram, applying the one or more picture quality adjustments to the raw image data of the digital image to generate an improved digital image, the improved digital image having a higher picture quality than the digital image, and displaying the improved digital image on a display device.
