Description
Claims (4)
- ディスプレイシステムのための駆動回路であって、前記ディスプレイシステムは各々が複数の画素を含む複数のピクチャラインを有し、前記駆動回路は、表示されるべきビデオデータのためのメモリであって、前記ビデオデータ用のメモリアドレスの各々が前記ピクチャラインの各々のラインアドレスを示すラインポインタを有するメモリと、前記ビデオデータを前記メモリに書き込む及び/又は前記メモリから読み出すシーケンスを制御するためのアドレスシーケンサであって、前記メモリに接続されるアドレスシーケンサとを有し、前記メモリは、複数のラインポインタのテーブルを含み、前記アドレスシーケンサは、アドレステーブルレジスタ手段と、前記メモリの前記ラインポインタのテーブルから前記アドレスレジスタテーブル手段に転送されるラインポインタのブロックと、ラインポインタのブロックの最後のラインポインタがアドレステーブルレジスタから読み出されたときに前記アドレステーブルレジスタ手段をラインポインタの次のブロックで連続的に更新する手段と、ピクチャライン内における画素の数を提供する画素カウント手段とが備えられ、前記画素カウント手段の出力は、前記アドレステーブルレジスタ手段からのラインポインタと協働して、前記ビデオデータ用のアドレスを決定する、駆動回路。
- 切替手段が備えられ、それによって、交互に、第1のモードにおいてビデオデータ用のメモリアドレスが前記アドレスシーケンサで発生し、第2のモードにおいて前記アドレステーブルレジスタがラインポインタの次のブロックで更新される、請求項1に記載の駆動回路。
- 前記メモリが、表示されるべきビデオデータの異なるシーケンスに対するラインポインタのフルテーブルを有する、請求項1又は2に記載の駆動回路。
- 表示システムと請求項1乃至3のうちのいずれか1項による駆動回路とを有する、画像を表示する装置。
