1. A system comprising:
processing circuitry configured to provide image data; and
an electronic display configured to display the image data;
wherein the processing circuitry or the electronic display, or both, are configured to monitor an instantaneous average pixel luminance of the electronic display and perform luminance scaling on a subset of a current frame of the image data based at least in part on the instantaneous average pixel luminance to prevent the electronic display from exceeding a power threshold when displaying the current frame of the image data on the electronic display, and wherein the instantaneous average pixel luminance corresponds partly to rows of the current frame of the image data and partly to rows of a previous image frame.
