To perform partial luminance adjustment in a screen, while suppressing a load increase of hardware resources.SOLUTION: A display unit 20 displays information indicating the state of a vehicle as a graphic image. A GPU 16 includes a programmable shader 16a which draws color in a unit of a pixel, and generates the graphic image displayed on the display unit 20. A CPU 12 designates contents of the graphic image displayed on the display unit 20, to the GPU 16. The CPU 12 can designate a luminance for each pixel of the graphic image displayed on the display unit 20, to the GPU 16. The programmable shader 16a corrects the color drawn in the unit of the pixel according to luminance information set from the CPU 12.SELECTED DRAWING: Figure 1 【課題】ハードウェア資源の負担増加を抑制しつつ、画面内の部分的な輝度調整を行う。【解決手段】表示部２０は、車両の状態を示す情報をグラフィック画像で表示する。ＧＰＵ１６は、画素単位で色を描画するプログラマブルシェーダ１６ａを含み、表示部２０に表示させるグラフィック画像を生成する。ＣＰＵ１２は、ＧＰＵ１６に、表示部２０に表示させるグラフィック画像の内容を指定する。ＣＰＵ１２はＧＰＵ１６に、表示部２０に表示させるグラフィック画像の画素ごとに輝度を指定可能であり、プログラマブルシェーダ１６ａは、ＣＰＵ１２から設定される輝度情報に応じて画素単位で描画する色を補正する。【選択図】図１
