Description
8 表示制御装置としてのタイミングコントローラ
11 検出手段としてのカウンタ部
12 判定手段としてのモード判定回路
13 制御手段としての制御信号生成回路
Claims (1)
- 周波数変調が加えられた外部からの入力信号に含まれる同期信号の水平周期を検出する検出手段と、
この検出手段にて検出した水平周期に基づいて入力信号に含まれる画像信号に対応した解像度を判定する判定手段と、
この判定手段により判定された解像度に対応して表示装置の駆動のタイミングを制御する制御手段とを具備し、
前記判定手段は、前記表示装置が第1解像度に対応して駆動している状態で水平周期が所定の下限閾値未満である場合に画像信号の解像度を前記第1解像度よりも小さい第2解像度であると判定し、前記表示装置が前記第2解像度に対応して駆動している状態で水平周期が前記所定の下限閾値よりも大きい所定の上限閾値以上である場合に画像信号の解像度を前記第1解像度であると判定し、
前記所定の下限閾値と前記所定の上限閾値との幅は、周波数変調が加えられた前記入力信号の同期信号の水平周期の変動幅よりも大きく設定されている
ことを特徴とした表示制御装置。
