ABSTRACT:
Systems and methods of automatically adjusting brightness of a digital image are provided. A particular method includes accessing data including a first digital image and identifying text and background in the first digital image. The method also includes calculating an average pixel value exclusive of the text and the background for the first digital image. The method further includes adjusting a brightness setting associated with the first digital image based on the calculated average pixel value.
