1. A method for brightness and contrast enhancement (BCE) of a digital image, the method comprising: computing a luminance histogram of the digital image; computing first distances from the luminance histogram to a plurality of predetermined luminance histograms; estimating control point values for a global tone mapping curve for the digital image from first predetermined control point values corresponding to a subset of the predetermined luminance histograms selected based on the computed first distances; and interpolating the estimated control point values to determine the global tone mapping curve.
