PROBLEM TO BE SOLVED: To provide a display control unit capable of improving the visibility of limited speed displayed on a display medium.SOLUTION: A display control unit 20 generates a first predetermined image which represents a first presentation image indicating a first limited speed on a display section 30. When the display section 30 detects a reduction of the limited speed for vehicles travelling on a road from the first limited speed to a second limited speed lower than the first limited speed and when the reduction is larger than a predetermined value, the display control unit 20 controls the display section 30 to display a second presentation image indicating a second limited speed when a first period of time has elapsed after terminating the display of the first presentation image on the display medium. When the reduction is smaller than a predetermined value, the display control unit 20 controls the display section 30 to display the second presentation image when a second period of time from zero to less than a first time has elapsed after terminating the display of the first presentation image.
【課題】表示媒体に表示される制限速度の視認性を改善する。【解決手段】表示制御装置20は、第1の制限速度を示す第1の提示画像を表す第1の所定画像を表示部30に生成させ、車両が走行する道路の制限速度の、第1の制限速度から第1の制限速度より低い第2の制限速度への減少を検知し、減少の幅が所定値以上のとき、表示部30を用いて、表示媒体における第1の提示画像の表示を停止させた後、第1の時間の経過後に、第2の制限速度を示す第2の提示画像を表示させ、一方、減少の幅が所定値未満のとき、第1の提示画像の表示を停止させた後、ゼロ以上かつ第1の時間未満である第2の時間経過後に、第2の提示画像を表示させる。【選択図】図11
