Description
通常、「濃度」については、黒に近いほど濃度が高く、白に近いほど濃度が低いことを意味するが、本願では、背景との比較において、背景とのコントラストが最大のものを最大濃度であるとの表現を用いることにする。
すなわち、背景が黒の場合には、「濃度」の通常の使用法とは、高低が逆になる。もちろん、背景が白の場合には、黒に近いほど背景とのコントラストが大きくなり、濃度も大きくなるから通常の用例と一致する。
そして、背景とのコントラストを最大にすると、残像時間が長くなるため、残像時間を短くするために、背景とのコントラストを最大値から低下させることに本願発明の技術的意義がある。以下に用いる「表示濃度」等の表現は、背景とのコントラストの趣旨と理解しなければならない。
すなわち、静止時の指針の画像濃度を100%とすると、移動速度が速くなるほど、画像濃度を100%から低下させ、また移動速度が遅くなるほど100%に近づくように変更する。画像濃度低下量は、次の(1)式で表される。
1a CPU
1a−1 移動速度算出手段
1a−2 表示濃度変更手段
1a−3 判定手段
1b ROM
1c RAM
2 グラフィックスインターフェース
3 LCDドライバ
4 液晶(LCD)パネル
