Abstract

Gain map generation, embedding, and application for high dynamic range digital image functionality are described. In one example, a gain map is generated based on a digital image, e.g., as a ratio of a standard dynamic range digital image and a high dynamic range digital image. The gain map is configured to adjust an amount of gain of a digital image between a high dynamic range (HDR) and a standard dynamic range (SDR). Metadata is generated based on the gain map. The metadata describes how the gain map is to be applied to the digital image as part of rendering. The gain map, the metadata, and the digital image are embedded within a digital image file and stored.
