ABSTRACT:
A graphical user interface for performing color correction and methods for implementing the color correction are disclosed. The graphical user interface allows a user to adjust the colorspace of the pixels in the image. In one embodiment, a user feedback system graphically informs the user if pixels near or exceed certain threshold values. For example, the graphical user interface may be placed into a luminance test mode. When in the luminance test mode, the color correction system tests the all the pixels in an image to determine if the luminance of each pixel is close to or above an acceptable luminance threshold value. If the luminance value is close to or above the threshold value then an alert is displayed on the graphical image. In one embodiment, the alert is an icon and area of the image that exceeds the luminance threshold is highlighted with zebra striping.
