Abstract

　ユーザの経験の有無を問わず、容易にかつ精度よくビデオ映像の輝度レベルを把握できる表示方法および装置を提供する。 　ビデオ映像のビデオ信号の輝度レベルを色情報に変換して、ビデオ映像の輝度の変化を色の変化として表示する。前記変換は、複数の重み付けのそれぞれに応じて、赤色、緑色、青色の三原色の色情報に変換する方法、所定の範囲の輝度レベルを輝度レベルの変化率よりも大きな変化率をもつ色情報に変換する方法、所定の範囲外にある輝度レベルを最大または最小のレベルの色情報に変換する方法等であることが望ましい。また、入力したビデオ映像と変換されたビデオ映像を並べてあるいは重ねて表示することが望ましい。
