<p>The present invention comprises methods for calculating and selecting tone curves for image enhancement. Once an image has been analyzed (130) and characteristics have been determined, a tone scale map may be calculated or selected (132) from a set of pre-calculated maps based on the value of the image characteristic. This map may then be applied (134) to the image to compensate for backlight adjustment or otherwise enhance the image.</p> |
