Abstract: Systems and techniques directed at dynamic power-saving mechanisms for displaying an image are disclosed. An electronic device determines an image to be displayed and an associated OPR for displaying the image. Based on the determined OPR, the electronic device generates a bionic image. Various mechanisms may be used to generate the bionic image. A display brightness value (DBV) or different blocking areas of the combined image may be used to generate the bionic image. The electronic device combines the image and the bionic image to form a combined image and presents the combined image on an emissive display. The combined image reduces a power expenditure of the emissive display that may otherwise be expended. The combined image may retain a high luminance for a focus area of the combined image while reducing the luminance for the remaining area (e.g., area outside of the focus area) of the combined image.
