1. A computer-implemented method comprising:
displaying a frame at a display device during a frame period, the display device having a plurality of individually-controllable illumination regions;
determining a brightness representation for each of the illumination regions for the frame; and
setting, for each illumination region, an illumination configuration to be applied by the display device for the illumination region during at least one of the frame period and a subsequent frame period based on the determined brightness representation for the illumination region, wherein setting the illumination configuration includes specifying one or more of an illumination level of an illumination strobe or an illumination level of an illumination fill.
