1. A method for processing a digital image comprising:
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;
displaying the improved digital image on a display device; and
generating the lower resolution histogram by:
assigning each pixel of the raw image data to a bin of a plurality of bins of the lower resolution histogram; and
for each bin of the lower resolution histogram:
calculating a representative pixel intensity value of pixel intensity values assigned to that bin; and
assigning the representative pixel intensity value to each pixel in that bin.
