Abstract: An apparatus and methods for modifying gradation in an image frame determine a blend factor indicating a first weighting associated with a previously processed portion of the image frame. The apparatus and methods generate a weighted value associated with a current region of the image frame based on the current region of the image frame and based on applying the first weighting to the previously processed portion of the image frame so as to modify the gradation in the image frame.
