Abstract
Innovations in rendering of high dynamic range ('HDR') content are described. A playback system can dynamically and proactively adjust the brightness level of a target display device. In some cases, this can reduce power consumption when rendering HDR content, without any noticeable degradation in quality. For example, the playback system includes decision logic. The decision logic is configured to receive summary information for sample values of a picture of HDR content and determine (based at least in part on the summary information) a brightness level of the target display device. The playback system can send, to the target display device, a control signal that indicates the brightness level of the target display device. A tone mapper can be configured to apply tone mapping to input values for the sample values of the picture of HDR content, according to a tone mapping function, and thereby produce output values.
