1. A display control system comprising:
a processing device configured to:
calculate global dimming information for global dimming control on a backlight of a display device including a display panel and the backlight; and
perform color correction on initial data based on the global dimming information to output image data; and
a circuit device configured to perform display control on the display device based on the image data from the processing device, wherein
the circuit device includes:
a distortion correction circuit configured to perform distortion correction on the image data to output corrected image data;
a dimming control circuit configured to calculate, based on the corrected image data and the global dimming information, local dimming information for local dimming control on the backlight; and
a light source control circuit configured to perform light source control on the backlight based on the local dimming information from the dimming control circuit.
