Abstract
High dynamic range (HDR) support is provided for legacy application programs, such as games that are configured to display standard dynamic range (SDR) frames. HDR frames may be generated without modifying the legacy application program. The buffer creation process of the legacy application program is intercepted and modified before creation of the SDR format buffer so that the buffer is configured to use an upgraded SDR format having an increased bit depth compared with a conventional SDR buffer. Rather than tone mapping and quantizing rendered image data to the lower bit depth for storage in the conventional SDR buffer, the rendered image data is tone mapped and quantized for storage at the increased bit depth of the upgraded SDR buffer. Therefore, the luminance and greater dynamic range of the tone mapped data is better preserved compared with outputting conventional SDR frames.
