Claims (3)
- 1.テレビ機器での偏向ラスタの位置を調整するための方法であって、画像スク リーンに本来の画像の他に、交点を有する格子パターンが結像され、該交点に対 するラスタ補正値が検出されて記憶される、テレビ機器での偏向ラスタの位置を 調整するための方法において、 −画像(2)を画像スクリーン(1)に対して正確なセンタリング位置にセンタ リングし、−格子パターン(SH,SV)を生成する制御パルスの時間的位置を 偏向ラスタに対して相対的に次のように調整し、すなわち該格子パターン(SH ,SV)が画像スクリーン(1)上で対称的目標位置をとるように調整すること を特徴とする、テレビ機器での偏向ラスタの位置を調整するための方法。
- 2.前記画像(2)のセンタリングを、偏向コイルを流れる直流電流の変更によ り行う、請求の範囲第1項記載の方法。
- 3.前記制御パルスの時間的な位置の変更をカウンタの初期状態の変更により行 い、該カウンタは水平格子線(SH)に対する制御パルスの生成のために所定の ライン数を計数し、さらに垂直格子線(SV)に対する制御パルスの生成のため に、ライン周波数よりも高い周波数を有するパルス列の所定のパルス数を計数す るものである、請求の範囲第1項記載の方法。
