Zusammenfassung:A method for video tone mapping includes receiving an overlay indication from an input data stream indicating whether a graphic is being overlaid on image data for a High Dynamic Range (HDR) scene. Based on the overlay indication, a hardware processor processes a video stream using a first tone mapping function to generate a first tone mapped video, or a second tone mapping function to generate a second tone mapped video.
