Description
図1は本発明の実施の形態1の画像表示装置において切替ショックを抑える方法を説明するための図である。図1(a)に示すように、表示画像の中に例えば四角い動画領域が検出されたとする。本発明の実施の形態1においては図1(b)に示したように、動画領域と静止画領域の間に動画領域として処理される画素と静止画領域として処理される画素とが混在する遷移領域を設ける。そして遷移領域内の動画領域に近い領域では、動画領域として処理される画素(以下、「画素A」と略記する)の比率が高く、静止画領域に近い領域では、静止画領域として処理される画素(以下、「画素B」と略記する)の比率が高くなるように、遷移領域内の各画素に対して画像信号処理を行う。
図7は本発明の実施の形態2における画像表示装置の構成を示す回路ブロック図である。図7において図3と同じ構成要素については同じ符号を用いて説明を省略する。
2×(水平LSB信号 XOR 垂直LSB信号)+(水平LSB信号)
を用いて計算することにより、画像表示装置上の位置に応じて各画素には0〜3のいずれかの値(以下、「ディザ要素」と呼ぶ)が設定される。
107 静止画符号部
108 動画符号部
109 セレクタ
300,400 選択部
305,405 選択信号発生部
310 乱数発生部
411 水平カウンタ
412 垂直カウンタ
Claims (1)
- 1フィールドを輝度で重み付けされた複数のサブフィールドで構成し、階調を表示するために各サブフィールド毎の画素の発光または非発光を制御する符号化を行うように構成するとともに、動画領域の画素に対する符号化を行う動画符号部と、静止画領域の画素に対する符号化を行う静止画符号部とを有する画像表示装置であって、
入力画像信号から動画領域を検出する動き検出部と、この動き検出部からの動き検出信号を複数の閾値と比較することにより前記動画領域と静止画領域との間に複数の遷移領域を作成するための遷移領域作成部と、この遷移領域作成部で作成された遷移領域において前記動画符号部の出力と前記静止画符号部の出力とのいずれか一方を選択する選択部とを備え、前記選択部は、前記動画領域において前記動画符号部の出力を選択するとともに、前記静止画領域において前記静止画符号部の出力を選択し、かつ前記遷移領域において、動画領域に近い遷移領域では前記動画符号部からの出力が選択される確率を高くするとともに、静止画領域に近い遷移領域では前記静止画符号部からの出力が選択される確率を高くするように構成したことを特徴とする画像表示装置。
