Claim:
A method to improve the display management of images, the method comprising: receiving first information data for a reference display, the first information data comprising a black point level, a white point level, and a mid-point level for the reference display; accessing second information data for a target display, the second information data comprising a black point level, a white point level, and a mid-point level for the target display; determining a transfer function to map pixel values of an input image signal to corresponding pixel values of an output image signal using the first and second information data, wherein the transfer function comprises three anchor points, wherein the first anchor point is determined using the black point levels of the reference and target displays, the second anchor point is determined using the white point levels of the reference and target displays, and the third anchor point is determined using the mid-point levels of the reference and target displays; and mapping the input image signal to the output image signal using the determined transfer function.
