Abstract: Systems and methods are described herein to control brightness based on image content or other inputs to a display system. A dual-control system may integrate both slow control operations and fast control operations into a cohesive brightness management system. By using both shorter-term (e.g., fast control) and longer-term (e.g., slow control) brightness adjustment operations, the electronic device may quickly respond to high luminance and high brightness situations that may cause burn-in into the display, image artifacts, or other damage. Responding quickly to these high consumption situations may prevent damage or perceivable upset to an ongoing process, among other benefits.
