Display Control Device and Display Device

A display control device comprising:

• a target average value calculation unit that sets, in a case where an image is divided into a plurality of areas and a plurality of display control devices controls display of the image in respective areas, the image in one of the plurality of areas as a display control target and calculates a target average value that is an average value of luminance of the display control target;
• a transmission unit that transmits the target average value calculated by the target average value calculation unit to another display control device;
• and
• a luminance information reception unit that receives, from the another display control device, luminance information regarding luminance of a whole of the image, the luminance information corresponding to an overall average value that is an average value of the luminance of the whole of the image calculated with use of the target average value.

A display device comprising:

• an image acquisition unit that acquires, in a case where an image is divided into a plurality of areas and a plurality of display control devices controls display of the image in respective areas, the image in one of the areas as a display target, the areas being display control targets of the display control devices connected to the display device;
• a supply unit that supplies a temperature of the display device to the display control devices connected to the display device;
• a display control information acquisition unit that acquires display control information to be used for control of display luminance of the image, the display control information being calculated on a basis of the temperature by the display control devices connected to the display device;
• and
• a display section that displays the display target acquired by the image acquisition unit with display luminance corresponding to the display control information acquired by the display control information acquisition unit.
