ABSTRACT:
Techniques are described for adaptive changing a displayed foreground color when a conflict between the displayed foreground color and an extracted background color is detected. Upon detection of such a conflict, a new foreground color is selected in accordance with a predetermined legibility criterion. That is, a color pool candidate may be considered to be a viable foreground color if a legibility value for the candidate color in relation to the extracted background color exceeds a predetermined legibility threshold value.
