Abstract
The present invention introduces an intuitive system for digital processing. The system of the present invention allows a user to enhance digital images that appear dark or dull. In one embodiment, the user activates an image enhancement button on a graphical user interface using cursor control device such as a mouse button. In one embodiment, the digital image enhancement system is implemented using a nonlinear brightness level transformation correction and a pseudo gamma correction. The parameters for both the nonlinear brightness level transformation correction and a pseudo gamma correction are determined from examining the properties of the image to be enhanced.
