PROBLEM TO BE SOLVED: To perform centralized operation screen display in a state that good visibility is secured even if an illumination environment changes in an operation room.SOLUTION: A centralized control device includes: a control part 51 for controlling touch panels 21 and 22 for centralizedly displaying parameters of instruments to be controlled in an operation room, and acquiring color set value information on a room lamp 5 and a shadowless lamp 6 in the operation room； and a recording part 54 for recording a display screen color table for setting color information related to the touch panels 21 and 22 corresponding to the color set values of the room lamp 5 and the shadowless lamp 6 in the operation room. When the color set values of the room lamp 5 and the shadowless lamp 6 change, the control part 51 selects the color information related to the touch panels 21 and 22 corresponding to the color set values based on the display screen color table stored in the recording part 54, and switches the color of the display screen.SELECTED DRAWING: Figure 2【課題】手術室において、照明環境が変化しても良好な視認性を確保した状態で集中操作画面表示を行い得る。【解決手段】手術室内の被制御機器のパラメータを集中表示するタッチパネル２１，２２を制御し、手術室の部屋灯５、無影灯６の色設定値情報を取得する制御部５１と、手術室の部屋灯５、無影灯６の色設定値に対応したタッチパネル２１，２２に係る色情報を設定する表示画面色テーブルを記録した記録部５４と、を備え、制御部５１は、部屋灯５、無影灯６の色設定値が変化した際に、記録部５４に記憶した表示画面色テーブルに基づいて当該色設定値に対応した前記タッチパネル２１、２２に係る色情報を選択し、表示画面の色を切り替える。【選択図】図２
