High dynamic range (hdr) displays can show images with higher color contrast levels and peak luminosities than the common low dynamic range (ldr) displays. However, most existing video content is recorded and/or graded in ldr format. To show ldr content on hdr displays, it needs to be up-scaled using a so-called inverse tone mapping algorithm.

High-dynamic-range imaging (hdri or hdr) is a collection of hardware and software technologies that allow the capture, processing, and display of image and video content containing a wide range of intensities between the darkest and brightest areas of an image. Lighting conditions in both natural and man-made environments can range from starlight to artificial illumination to bright sunlight.
