Description

1289993 五、發明說明(1) 一、 【發明所屬之技術領域】 本發明係有關於影像或圖像的重疊方法與系統,特別 是關於調整多個影像或圖像〉昆色比例之重疊方法與系統。 二、 【先前技術】 在動態影像畫面顯示上’通常用於整合與顯示影像與 圖像的方法,分別為單圖幅缓衝區架構(single frame buffer architecture)與雙圖幅緩衝區架構(duai frame buffer architecture)。其中,在雙圖幅緩衝區架構上決 定顯示影像或圖像二者之一的作法,係為在圖像子系統上 以個別像素一個接一個來決定,一般係以一特定顏色或以 查詢色彩對照表(l00kup table)之—特定顏色項(;〇1〇; HI : T式找出所謂關鍵色度(Chr〇ma —_),而另 :Πί;做所謂的黑色们則’即利用黑色最容易被偵測 而將黑色也視為某種關鍵色度。這兩箱祚本 將圖像像素視為透==(如關鍵色度或黑色)時, 像與圖像重4顯_ :讓衫像顯⑨。第-圖係-習知之影 像11 0所構成,\^不思圖,顯不畫面15 0係由影像1 〇 0與圖 示畫面15〇ί之;中影像100與圖像110係各自將相對於顯 達’而在圖像j二位置的!素’在同-時間内逐-送 圖像像素流该、去々有一重疊區域12〇以關鍵色度填滿,在 夕工器1 30過程中,以一偵測器丨4〇檢查有 1289993 五、發明說明(2) 無關鍵色度,當錢到時,則多工器13Qit# 像素輸出,反之以圖像110的像素輸出。 以影像1 0 0的 根據上述的 像與圖像以某一 (transparency 塊之像素輸出皆 之紅綠藍色值就 疋比例的混色, 度透明度混色, 時,上述重疊顯 方法雖可讓影像重疊在圖像上,或是將影 比例做混合達到具有透明度混色 mix/b lend)的效果,例如,當某一特定區 以固定1/4紅綠藍色值影像及加上3/4圖像 月匕產生重$或半透明效果,但是,這種固 例如希望能將重疊區域以多個各種不同程 或做到由糢糊逐漸清楚的淡入淡出等效果 示方式便限制了應用彈性,並且先前技術 多限於將-圖像與m圖像重疊在一畫面上 ΛΑ Jlfl -Jt—办 ^ " 面的來源有多個 的方式,在動態 圖像或影像時,直接覆蓋或固定混色比例 影像的應用彈性稍嫌不足。 三 發明内容 本發明提供一種以像素為基礎的可調式混色方法,首 先依據複數個輸入訊號分別取得相對應之一像素與一可調 整之混色比例;以及依據一混色法以產生一輸出像素。 本發明再提供一種以像素為基礎的可調式混色系統, 包括·一像素與混合比例產生器,係用以根據複數個輸入 訊號分別產生相對應之一像素與一混合比例;以及一混合

之紅色值、綠色值與藍色值分別不大於63、31與63,並且 各個混色值加總後所產生之輸出像素之紅色值、'綠色值與 藍色值亦分別不大於63、31與63。 ’、 此外,透過動態變更顏色項内容,可以讓不同訊號之 内容所產生的之像素色彩相同,混合比例卻不同;也可以 是訊號内容不變,動態調整混合比例來達到特殊顯示效 果。例如,當某一訊號之内容為A、B、C、D與E時,經4查 表對應後產生之像素皆為色彩1,但是混合比例分別為混 合比例100%、75%、50%、25%與0%,如此就能將此訊號所 產生之像素在不同時間呈現出以色彩1逐漸變淡,最後消 失的視覺效果。 因此’母個訊號來源僅單純地傳送與像素相關之訊號 内容,不同混合比例之相同像素以不同訊號内容來傳送, 如此就不需同時傳送像素與混合之資訊,在訊號來源方面 就可省下大量的儲存與傳輸成本。例如,在一1〇24χ768的 畫面上,如果每一像素相關之混合比例需以8位元來表 不,每一晝面就需6, 291,456個位元,在每秒3〇個畫面的 顯示上,將會是很大的成本。 第三A圖係本發明之一種以像素為基礎的混色系統示 思圖-較佳實施例,包括一像素與混 產生器3〇〇, 係用以根據複數個輸入訊號產生與各 1289993 五、發明說明(6) 像素與一混合比例;以及一混合器340,係用以依據一混 色法以及這些像素與混合比例以產生一輸出像素。第三B 圖係本發明之一種以像素為基礎的混色系統示意圖另一較 佳實施例,其中此像素與混合比例產生器3 〇 〇尚可包括多 個可程式化之對照表31 01至31 0N,係用以根據各輸入訊號 對應到一對照表之一顏色項,以輸出相對應之像素;以及 尚可包括多個混合比例產生器3 2 0 1至3 2 0 N,每一個混合比 例產生器係用以接收一輸入訊號,以產生相對應之混舍比 例。本實施例之混色方法及其相關細節皆與前一實施例相 同,故在此不再贅述。
