Abstract
Methods for encoding transitions between low-intensity regions and high-intensity regions such that the transitions are more readily detectable in a digital image captured by a digital image capture device. The encoding applied to the transitions act to retard and minimize blooming effects and ISI that can occur in the digital image, especially when the transitions are captured from a television, computer display screen or other transmissive media.
