Abstract:
An original image is received. The original image is divided into tiles. A whitepoint value of each tile is determined. A blackpoint value of each tile is determined. A whitepoint value of each pixel in the image is determined by interpolating the determined whitepoint values of neighboring tiles. A blackpoint of each pixel in the image is determined by interpolating the determined blackpoint values of neighboring tiles.
