^36754 五、發明說明(1) 理方i Πΐ關於尤指減少大面積閃爍效應之視頻圖像處 盖體而言,本發明密切關係到-種視頻處理,以改 。陣顯不器,像電漿顯示屏(PDP),具有數位式& 變理a ^ 、裝置,以基於光射任務循環調變(脈寬調 變)原理的各種顯示器等所顯示的圖 背景 趣日@ Γ電漿顯示屏已公知多年,在電視機廠家方面卻興 β。誠然,此頊技術可達成大型的平坦彩色屏,深度 咏推i不會有任何視角拘束。顯示器的尺寸遠較傳統CRT 映像官所容許者為大。 ^見最近生產的歐洲電視機,費很多精力於改進其圖 因此’巫需提供像電漿顯示技術等新技術製造的 視機’可嫂美或優於舊式的標準電視技術。 電漿續示屏利用只能切換「開」或「關」的放電電池 之矩陣排列。與灰調以光射類比控制表現的CRT或LCD不同 在PDP裡的灰調是藉調變每框的光脈波數來控制。此項 人間調變可利用眼睛經過相當於眼睛時間響應之期間來整 合°對靜態圖像而言,此項時間調變本身重複的基礎頻率 等於所顯示視頻基準的框頻。由CRT技術已知,基礎頻 率為50赫之光射,引進大面積閃爍,可在100赫CRT電視接 收機内’利用圖場複演率消除。 與CRT相反的是,光射的任務循環極短,pDp内的光射 任務循環對中度灰而言為〜5〇 %。此減少光譜内因此大面
第6頁 436754 五、發明說明(2) 積閃爍假象内50赫頻率成份之幅度,但由於pDp尺寸較大 ’有較大視角,即使減少大面積閃爍,在圖像品質方面仍 不能接受。增加PDP尺寸和亮度的目前趨勢,也會使問題 在未來更加惡化。 發明概要 本發明之目的’在於揭示特別是在5〇赫視頻基準的 PDP内減少大面積閃爍假象之方法和裝置,不會引起類似 100赫電視接收機所需的額外成本。 此項目的可由‘申請專利範圍第丨和9項之措施達成。 按照申請專利範園第1項的解決方案,減少大面積效 應是利用框週的最佳副場組織為之。圖素的副場是以二連 續組加以組織’而對圖素值指定編碼字,於有源副組期間 ’平均分配於二副場組。 此項方案的效果是,與使用唯一副場組的副場紕織相 較’ 5 0赫頻率成份實質減少s 5 〇赫重照明時期的重複,以 1 0 0赫小照明時期的重複所代替。使用此法,實際上不加 額外成本,惟稍微增加PDP控制的複雜性。 本發明較佳的附加具體例,載於申請專利範圍各附屬 項。使用二副場組(最重要的副場)相同結構,有助於確 保二照明時期有類似的特性(見申請專利範圍第2項)[最 不重要的副場權值小,不會引起重大的大面積閃爍。此即 何以最不重要副場不需在二副場組内一致的理由。 為了在一如錄影機或視頻遊樂器中所發生之水平線同 步k號變化申,亦可顯示非標準視頻信號,需用到無副場
^36754 五、發明說明(3) 定址之垂直遮沒期(見申請專利範圍第4項)。於此,垂直 遮沒期宜改用二垂直遮沒期,插入於每一對接續副場組之 間。此與1 00赫CRT質的電視接收機所發生者類似。 申請專利範圍第5項所請求的具體副場組織,有益於 50赫視頻基準’與NTSC等60赫視頻基準的最佳副場組織相 較,可容易使用更多副場,因為框週較長。 申請專利範圍第9項揭示之裝置較佳具體例,從申請 專利範圍第ί 0和1 1項即可明白。 圖式簡單説明’ 本發明具趙例如圖所示,可詳述如下□圖中 第1圖為PDP副場概念之說明圖; 第2圖為6 0赫視頻標準所用典型副場組織圖; 第3圖為5 0赫視頻標準所用新副場組織圖; 第4圖為本發明裝置之方塊圖。 較佳具體例之說明 在視頻處理場中,8位元表示亮度位階非常普遍。在 此情況下,各位階可以如下8位組合表示: 2。-1’ 2!=2, 22 = 4, 23 = 8, 24 = 16, 25 = 32, 26 = 64, 27:128 技術實現此種編碼計劃冑,框週要分成8個照明 期,吊稱為副場’各相當於8位元之一。位元2]=2之光脈 波為2。= 1之加倍,以此8副期的組合,即可建立該託6 二n=立階’例如灰調位階92即可有相當於位元編碼字 =00。須知副場係由許多同等幅度且同等期限的小 脈波組成1察者的眼睛不用動’可在約!個框週内整合
436754 五、發明說明(4) 全部期’而有正確灰調位階的印象’上述副場組織如第 1圖所示。 PDP的大部份發展係為60赫視頻標準,例如NTSC。對 此等視頻標準已知更好是使用精製之副場組織,以避免假 象,並改進圖像品質。 60赫視頻組織的常用副場組織例,見第2圖所示。副 場數增加至1 2個副場SF,副場之相對期限如第2圖所示。 當全部副場起動時,照明階段有2 5 5個相對時間翠位之相 對期限。選用255值‘是為了可以繼續使用上述亮度位階之8 位元表示,或PDP所用之RGB資料。七個最重要副場具有32 個相對時間單位之相對期限。在PDP技術場,副場的相對 期限富稱為副%「權值」,以下亦用此表達。各副場s F ’間 有小時期不發射光。此時期用於相對應電漿晶胞的設址。 最後副場之後’加不發射光的較長時期。此時期相當於視 頻標準的垂直遮沒時期。此垂直遮沒時期必須實施,以處 理VCR或視頻遊樂器等所發生的非標準視頻信號。 在此副場組織内灰調位階92的數位式表現,是例如 000001111100。此數字為12位元二進數,相當於12個副場 可在框週内,用來控制相對應圖素之照明脈波。須知在 同樣灰調位階,有少數其他可能的12位元編碼字存在,因 為事實上有七個副場寬度一致的權值。 第3圖表示本發明供&〇赫視頻標準用之新副場組織, 60赫視頻標準的框週為16.6ms,5〇赫為2〇ms,故5〇赫視頻 標準較長。此舉容許有更多副場設址在5〇赫視頻標準内。
