To provide a display control unit stably obtaining visibility of image display from startup of a vehicle and obtaining smooth image display when the vehicle is travelling.SOLUTION: The display control unit functionally comprises: a temperature acquisition unit S132 that acquires current temperature Tp of a liquid crystal panel; pixel selection units S120, S121 that select, from pixel groups composing the liquid crystal panel, an intermediate luminance pixel given an intermediate luminance value Lm by antialiasing; a period regulation unit S130 that regulates an initial update period Pi using the vehicle startup as a starting point; luminance correction units S131, S133, S134, S135, S136, S137 that update correction of the intermediate luminance value Lm according to current temperature Tp acquired by the temperature acquisition unit in the initial update period Pi regulated by the period regulation unit while stopping the update according to the current temperature Tp when the initial update period Pi elapses from the startup; and a pixel drive unit S14 that drives the intermediate luminance pixel selected by the pixel selection unit based on the intermediate luminance value Lm corrected by the luminance correction unit.SELECTED DRAWING: Figure 5

    【課題】車両の始動から画像表示の視認性を安定且つ車両の走行時には円滑な画像表示を達成する表示制御ユニットの提供。【解決手段】表示制御ユニットは、液晶パネルの現在温度Tpを取得する温度取得部S132と、液晶パネルをなす画素群のうちアンチエイリアス処理により中間輝度値Lmが与えられる中間輝度画素を選択する画素選択部S120,S121と、車両の始動を起点として初期更新期間Piを規定する期間規定部S130と、期間規定部により規定の初期更新期間Piに、温度取得部により取得の現在温度Tpに応じて中間輝度値Lmの補正を更新する一方、始動から初期更新期間Piが経過すると、現在温度Tpに応じた更新を中止する輝度補正部S131,S133,S134,S135,S136,S137と、画素選択部により選択の中間輝度画素を輝度補正部により補正の中間輝度値Lmに基づいて駆動する画素駆動部S14とを、機能的に構築する。【選択図】図5
