Abstract

　液晶駆動パネルに対して、外部から入力される複数の画素データからなる画像信号を補正するデータ処理装置において、補正回路が、補正対象となる第１の画素データ、および、該第１の画素データに基づいて駆動される上記データ信号線と同じデータ信号線で、該第１の画素データによる駆動タイミングよりも前に駆動に用いられる第２の画素データを取得し、第２の画素データの値と第１の画素データの値との関係に応じて第１の画素データを補正する補間演算部を備える。これにより、特定のデータ信号線において、前に印加された電圧の影響が画素に対する充電状態に影響を与える場合に、この影響を相殺するような補正を行うことを可能とするデータ処理装置を提供する。
