11. A method for adjusting an image for increased brightness, said method comprising:
-
a) adjusting the code values of a first group of image pixels to increase the perceived brightness of said pixels by applying a gain factor function; and
b) adjusting the code values of a second group of image pixels according to a transition function that transitions from said gain factor function to no gain at a maximum value point. - View Dependent Claims (12, 13, 14, 15)
