1. A method for predicting a high dynamic range image element, said method comprising: receiving, in a video coder, a plurality of low dynamic range (LDR) image data; generating, in said video coder, a first predicted high dynamic range (HDR) prediction parameter value based on said plurality of LDR image data; extracting, in said video coder, an LDR image value from said plurality of LDR image data; and forming, in said video coder, an HDR image element prediction using said first predicted HDR prediction parameter value and said LDR image value.
