High dynamic range codecs

Abstract

In order to obtain an efficient and backwards-compatible encoding of a high-dynamic range image, a method for encoding a high dynamic range (hdr) image is provided, comprising the steps of obtaining an ldr image; generating a prediction function; storing the prediction function together with the ldr image; characterized in that the prediction function is based at least in part on pixel values of the pixels in the hdr image for which corresponding pixels in the ldr image all have the same pixel value.
