Description

515207 A7 B7 五、發明說明（1 ) [技術領域] 本發明有關於攝影裝置，尤其有關於使用單板式之攝 影元件之攝影裝置之影像信號處理方法。 [背景技術] 第3 0圖表示單板式攝影元件所使用之代表性之色過 濾器之排列。下面將說明在此種過濾器排列之情況時 之色信號處理方法。 在第30圖中，Ye表示黃，Mg表示紫紅，Cy表示藍 綠，G表示綠2色過濾器。在依此方式排列色過濾器之 情況時，色信號處理之進行是進行水平方向鄰接之2個 圖素間之減算，以下式之方式取出與色信號（R-Y)，（B-Y) 相當之信號。 N 線 （Ye + Mg)-(Cy + G) = 2R-G.“（l) (N+1)線 （Cy + Mg)-(Ye + G) = 2B-G."(2) 由式（1)，（2)可以明白，在N線只能獲得與色信號（R-Y) 相當之信號，在（N+1)線只能獲得與色信號（B-Y)相當之 信號，因此在處理一樣之色之情況時不會有問題，但是 在N線和N+ 1線之間亮度有變化之情況時，G之値在N 線和N+1線會有很大之不同，所以會發生與本來之色不 同之色，稱爲僞色。因此，檢測亮度之邊緣，經由使邊緣 部之色之增益降低，用來除去僞色信號。 此種方式之實例，例如被揭示在日本國專利案特開昭 6 0 - 2 5 4 8 9 3 號公報。 第31圖是方塊圖，用來表示具有習知之僞色消除電 本紙張尺度適用中國國家標準（CNS)A4規格（210 X 297公釐） (請先閱讀背面之注意事項3寫本頁) · -丨線： 經濟部智慧財產局員工消費合作社印製 515207 五、發明説明（2 ) 路之單板式彩色攝影機之構造。 在第31圖中，符號3101是近物透鏡，3102是色過濾 器，3 1 0 3是固體攝影元件，3 1 0 4是緩衝放大器電路，3 1 〇 5 是頻帶濾波電路，3 1 0 6是解調電路，3 1 〇 7是全白平衡電 路，3 1 0 8，3 1 1 0是低頻濾波電路，3 1 0 9，3 1 1 1是處理電路 。符號3 1 1 2是邊緣部檢測電路，在該電路3 1 1 2中，符 號3 1 1 3是延遲電路，3 1 14是減算電路，3 1 1 5是檢波電 路，3 1 1 6是波形整形電路，3 1 1 7是延遲電路。3 1 1 8是編 碼電路，在該電路3118中，符號3119是調變電路，3120 是僞色消除電路，3 1 2 1是混合電路，3 1 2 2是亮度信號處 理電路，3 1 2 3是輸出端子。 在具有上述構造之習知之攝影機中，利用邊緣部檢測 電路3 1 1 2用來檢測表示亮度信號急激變化之邊緣部， 利用僞色消除電路3 1 2 0用來消除包含僞色之色信號。 但是在上述之習知方法中是經由使亮度之邊緣部之 色之增益降低用來抑制僞信號，因此此種方法會使本來 所需要之色亦被消除，會有造成畫質降低之問題，例如 會產生人之嘴唇變成無色之問題。 [發明之揭示] 用以解決上述問題之本發明之申請專利範圍第1項 是一種攝影裝置，使用單板式之攝影元件，其特徵是具 備有··色再現範圍記憶裝置，‘用來預先記憶攝影裝置之 色再現範圍；亮度信號算出裝置，用來算出輸入信號之 亮度信號；色信號算出裝置，用來算出輸入信號之色信 -4- )15207515207 A7 B7 V. Description of the Invention (1) [Technical Field] The present invention relates to a photographing device, and more particularly to an image signal processing method of a photographing device using a single-plate type photographing element. [Background Art] Fig. 30 shows an arrangement of a representative color filter used in a single-plate photographic element. The color signal processing method in the case of such a filter arrangement will be described below. In Fig. 30, Ye indicates yellow, Mg indicates magenta, Cy indicates blue-green, and G indicates a two-color green filter. In the case of arranging color filters in this way, the color signal processing is performed by subtracting two pixels adjacent in the horizontal direction, and the signals corresponding to the color signals (R-Y) and (B-Y) are taken out in the following manner. N line (Ye + Mg)-(Cy + G) = 2R-G. "(L) (N + 1) line (Cy + Mg)-(Ye + G) = 2B-G. &Quot; (2) by Equations (1) and (2) can be understood that only signals equivalent to the color signal (RY) can be obtained on the N line, and only signals equivalent to the color signal (BY) can be obtained on the (N + 1) line. There is no problem with the same color, but when there is a change in brightness between the N line and the N + 1 line, the difference between the G line and the N line and the N + 1 line is very different, so it will happen Colors that are originally different in color are called false colors. Therefore, detecting the edges of brightness and reducing the color gain of the edge portion is used to remove false color signals. An example of this method is disclosed in the Japanese patent case, for example. Japanese Patent Application Laid-Open No. 6 0-2 5 4 8 9 3. Figure 31 is a block diagram showing the conventional false-color-cancellation paper size applicable to the Chinese National Standard (CNS) A4 (210 X 297 mm) ) (Please read the note on the back 3 to write this page) ·-丨: Printed by the Intellectual Property Bureau Employee Consumer Cooperative of the Ministry of Economic Affairs 515207 V.

The symbol 3 1 1 2 is an edge In this circuit 3 1 1 2, the symbol 3 1 1 3 is a delay circuit, 3 1 14 is a subtraction circuit, 3 1 1 5 is a detection circuit, 3 1 1 6 is a waveform shaping circuit, 3 1 1 7 It is a delay circuit. 3 1 1 8 is an encoding circuit. In this circuit 3118, the symbol 3119 is a modulation circuit, 3120 is a false color cancellation circuit, 3 1 2 1 is a hybrid circuit, and 3 1 2 2 is a luminance signal processing circuit. 3 1 2 3 is an output terminal. In a conventional camera having the above structure, an edge detection circuit 3 1 1 2 is used to detect an edge portion indicating a sharp change in a luminance signal, and a false color cancellation circuit 3 1 2 0 is used. To eliminate color signals that contain false colors. However, in the conventional method described above, the color gain of the edge portion of the brightness is reduced. It is used to suppress false signals, so this method will also eliminate the originally required color, which will cause problems such as lowering the image quality, such as the problem of human lips becoming colorless. [Disclosure of the Invention] To solve the above The first item of the patent application scope of the present invention is a photographing device using a single-plate type photographic element, which is characterized by having a color reproduction range memory device, which is used to memorize the color reproduction range of the photography device in advance; the brightness signal Calculating device for calculating the luminance signal of the input signal; Color signal calculating device for calculating the color signal of the input signal -4-) 15207

因此，依照信號處理後之色是否在色再現範圍內，可以 -21- 五、發明説明（2G) 用來判別該色是否爲僞色。 在色再現範圍記憶電路1 0 5預先記憶以攝影裝置取 入之各種圖像樣本之可表現之色之範圍。因爲色再現 範圍爲亮度Y和色（R-Y)，（B-Y)之3次元資料，所以設 置3次元之記憶器，以輸入資料Y，（R-Y),(B-Y)之値作 爲位址，假如該色在色再現範圍內時，例如，就在色再現 範圍記憶電路1 0 5記憶1 ,在色再現範圍外之時，就記憶 0 〇 其次取入輸入信號，在亮度信號算出電路103算出亮 度信號，和在色信號算出電路105算出色信號。 使僞色判定電路1 06所算出之亮度信號和色信號，與 被記憶在色再現範圍記憶電路1 0 5之色再現範圍資料 進行比較，用來判定輸入資料是否爲僞色。亦即使亮度 信號資料和色信號資料參照色再現範圍記憶電路之位 址，當記憶之値爲1之情況時，因爲在色再現範圍內所 以判定爲不是僞色，當記憶値爲0之情況時，因爲在色 再現範圍外，所以判定爲僞色。 在僞色抑壓電路1 〇 7當僞色判定電路1 0 6判定爲僞 色之情況時就進行僞色之抑壓處理。僞色之抑壓之達 成是使色之增益減小或成爲〇。利用此種處理使輸入 信號之色之增益降低，可以用來抑壓僞色。在判定爲不 是僞色之情況時，使色之增益成爲1，直接使色信號通過， 不進行僞色之抑壓。 依照此種方式，在本實施例1之攝影裝置中，預先檢 -22- 515207 五、發明説明（21) 查攝影裝置之色再現範圍將其記憶在色再現範圍記億 電路1 〇 5，根據該資料用來判定該亮度信號算出電路和 色信號算出電路所算出之輸入資料是否在色再現範圍 內，藉以判定是否爲僞色，在判定爲僞色之情況時正確 的進行僞色抑壓用來抑壓僞色。 另外，在將色再現範圍記憶在色再現記憶電路1 0 5之 情況時，需要以不會產生僞色之條件進行攝影用來記憶 色再現範圍，其實現可以經由使攝影裝置之光學系統之 焦點成爲偏移狀態，記憶色再現範圍。 亦即，因爲僞色會發生在亮度邊緣之某個位置，所以 故意使焦點偏移，用來使売度之邊緣資訊變無，藉以使 僞色不會發生。記憶不會發生僞色之狀態之色再現範 圍，可以用來進行高精確之僞色抑壓。 另外，記憶色再現範圍之另外一種方法之實現可以預 先記憶使亮度信號和色信號分別平滑化後之資料。亦 即，因爲僞色發生在亮度邊緣之某個位置，所以利用平 滑化可以使邊緣部之色變無。下面將使用第3圖，第4 圖，第5圖用來說明此種情況之色再現範圍之記憶方 法。 第3圖表示記憶色再現範圍時之信號平滑化電路之 方塊圖。在第3圖中，符號3 0 6是亮度信號平滑化電 路，3 0 7是色信號平滑化電路。經由使亮度信號和色信 號分別進行平滑化，用來抑壓僞色，將僞色抑壓後之色 再現範圍記憶在色再現範圍記憶電路3 0 5。 -23- 515207 五、發明説明（22) 下面將說明該平滑化方法。 例如，在對具有白色（W)區域和黑色（BK)區域互相鄰 接之對象物進行攝影之情況時，信號處理過之圖素之排 列成爲如第4圖所示。在第4圖中，於境界部份發生僞 色，在此種情況所發生之僞色是紫紅（Mg)。此種情況之 (R-Y)信號之値如第5(a)圖所示。當信號之値爲8位元 資料時，（R-Y)成爲從0到2 5 5之値，在無彩色（亦即黑 色）之圖像中，（R-Y)之値變成爲128。因此，因爲本來 之境界部之左側爲白色，右側爲黑色，（R-Y)信號之値全 部變成爲1 2 8，但是僞色用之境界部之値變成爲紫紅色 之値2 3 4。 其中，使（R-Y)信號平滑化用來進行僞色變無之處 理。平滑化之方法有各種方法，例如可以使用„位.過遽_. 器進行平滑化。中位過濾器是在包含连f麗素之區域 中，以値之大小爲中央之値作爲注目圖素之値，例如對 於第5(a)圖之注目圖素，當對區域1施加中央過濾時， 因爲中央之値爲128,所以注目圖素之値變成爲128。 以此方式順序進行中位過濾時，處理結果變成如第5(b) 圖所示，僞色已被除去。 同樣的，對（B-Y),亮度信號亦進行平滑化處理。因爲 利用此種平滑化處理可以抑壓僞色，所以可以將沒有僞 色之色再現範圍記憶在色再現範圍記億電路。 另外，攝影元件之過濾器排列和亮度信號，色信號之 算出方法並不限於上述者，過濾器排列只要是單板式亦 -24- 515207 五'發明説明（23) · 可以使用任何一種之排列，亮度信號，色信號亦可以進 行適於其過濾器排列之信號處理。 (實施例2) 下面將參照第6圖至第11 _用來說明與本發明之申 請專利範圍之第4項，第5項，第6項，第7項和第8項 相當之攝影裝置作爲實施例2。 第6圖是方塊圖，用來表示本實施例2之攝影裝置之 構造。 在第6圖中，符號601是攝影元件，602是A/D變換 器，603是亮度信號算出電路，604是色信號算出電 路，6 0 5是色再現範圍記憶電路，6 〇 6是僞色判定電 路，6 0 7是僞色抑壓電路。 實施例2不是如同實施例1之將色再現範圍預先記 憶在色再現範圍記憶電路，而是記憶1個框架前之輸入 資料之色再現範圍。亦即，預先記億攝影裝置之所有之 色再現範圍需要非常多之時間和工時，所以經由不進行 該作業，從現在攝影之圖像記憶色再現範圍，可以更簡 單的記憶色再現範圍。 下面將說明具有上述方式之構造之攝影裝置之信號 處理動作。 利用攝影元件60 1所攝影到之影像信號在A/D變換 器602被數位化，然後被輸出到亮度信號算出電路603 和色信號算出電路604。在亮度信號算出電路603算 出之亮度信號送出到色再現範圍記億電路6 0 5和僞色 -25- 515207 五、發明説明（24) 判定電路6 0 6，另外，在色信號算出電路6 0 4算出之色之 信號送出到色再現範圍記憶電路6 0 5和僞色判定電路 606,及僞色抑壓電路607。 亮度信號和色信號之算出方法與實施例1相同，故其 說明在此加以省略。 色再現範圍之記憶方法之步驟是首先在第6圖之色 再現範圍記憶電路60 5記憶涵蓋1個框架之攝影裝置 之色再現範圍，從下一個框架起根據所記憶之色再現範 圍進行僞色抑壓，和將該框架之色再現範圍記憶在色再 現範圍記億電路60 5。 第7圖是以亮度Y,色（R-Y)，（B-Y)之3次元分割輸入 信號。在色再現範圍記憶電路6 0 5，如第7圖所示的將 亮度，色信號之3次元資料分割成爲多個區域，在輸入 資料爲各個分割區域之情況時，以該區域作爲色再現範 圍的進行記憶。 下面將使用第8圖用來說明色再現範圍之記憶方 法。 第8圖是檢查涵盡1個框架之色分布，將其結果投影 在Y,(R-Y)軸。本來之色再現範圍是Y，（R-Y),(B-Y)之 3次元資料，但是爲著使說明簡化，變換成爲投影在 Y，（ R - Y )軸之2次元資料，以此方式用來說明色再現範 圍之記憶方法。第8 (a)圖表示實際攝影到之1個框架 部份之色分布，在Y軸方向分割成個，在（R-Y)軸方 向分割成12之區域。檢查在每一個區域之圖素之分布， -26- 五、發明説明（25) 當區域內有圖素之情況時，和第8(b)圖之斜線部所示， 將其記憶在作爲色再現範圍之該區域。利用此種方式， 第8(b)圖之斜線部作爲色再現範圍的記憶，非斜線部之 區域作爲色再現範圍外的記憶。以上所說明之情況是 將3次元資料投影在2次元資料之情況，對第7圖所示 之區域進行3次元之分割，在其區域內有圖素之情況時， 就將該區域作爲色再現範圍，例如在記憶器記憶1，在區 域內沒有圖素之情況時，就將該區域作爲色再現範圍外， 記憶〇。 另外，在僞色判定電路6 0 6檢查輸入信號是否屬於第 7圖之被分割之區域，和參照色再現範圍記憶電路6 0 5 用來判定該區域是否在色再現範圍，假如被記憶之値爲 1時，因爲是色再現範圍內之色，所以判定爲非僞色，假 如被記憶之値爲〇,就判定爲僞色。 在僞色抑壓電路6 0 7，當利用僞色判定電路6 0 6判定 爲僞色之情況時就進行僞色之抑壓處理。僞色之抑壓 之進行是使色之增益減小或成爲〇。在判定爲非僞色 之情況時使色之增益成爲1，使色信號直接通過，不進行 僞色之抑壓。 另外，當將色信號之3次元資料分割成爲多個區域時， 不是如第7圖所示的分割成爲均等之區域，而是在色再 現範圍和僞色之境界附近，將亮度，色信號之3次元資 料分割成較細，在其以外之區域分割成爲較粗之區域， 在被分割之區域內有輸入資料之情況時，以該區域作爲 -27- 515207 五、發明説明（26) 色再現範圍的進行記憶。 彩色度較低之區域因爲一定在色再現範圍內，所以對 該區域進行較粗之分割，另外在彩色度很高之區域，對 於在色再現範圍外之可能性很高之區域進行粗分割，對 於其以外之中間之區域分割成爲細區域，記憶色再現範 圍，可以用來正確的檢查色再現範圍。第9圖是將與第 8圖相同之色再現範圍樣本投影在Y，（R-Y)軸上，在色 再現範圍和僞色之境界附近分割成較細之區域。第8 圖和第9圖之分割數相同，但是在第9圖可以檢查更細 之色再現範圍。另外，在第9圖是在（R-Y)軸上變化分 割方法，但是在（B-Y)軸上亦可以進行同樣之處理。經 由在彩色度很低和很高之區域進行粗分割，在其以外之 區域進行細分割，可以用來更正確的檢查色再現範圍。 另外，在將色再現範圍記憶到色再現記憶電路60 5之 情況時，必需記憶以不會發生僞色之條件進行攝影之色 再現範圍，但是亦可以如實施例1所述，記憶對亮度信 號和色信號分別進行平滑化後之資料。亦即僞色發生 在売度之邊緣之某個位置，所以利用平滑化使邊緣部之 色變無。此種情況之處理之方塊圖如第1 0圖所示。 在弟10圖中，付號1001是攝影兀件，1002是A/D變 換器，1003是売度信號算出電路，1〇〇4是色信號算出電 路，1 〇 〇 5是色再現範圍記憶電路，1 〇 〇 6是僞色判定電 路，1007是僞色抑壓電路，1〇〇8是亮度信號平滑化電 路，1 009是色信號平滑化電路。 -28- 五、發明説明（27) 依照上述之方式，經由增加設置亮度信號平滑化電路 1 0 0 8和色信號平滑化電路1 0 0

1圖是方塊圖，用來表示具有非聚焦狀態攝影裝 置之攝影裝置之構造。 在第1 1圖中，符號1 101是攝影元件，1 102是A/D變 換器，1103是亮度信號算出電路，1104是色信號算出電 路，1 1 〇 5是色再現範圍記憶電路，11 0 6是僞色判定電 路，1 1 〇 7是僞色抑壓電路，1 1 0 8是亮度信號微分電 路，1 1 〇 9是高頻成分計數器，1 1 1 0是非聚焦狀態檢測電 路，1 1 1 1是透鏡驅動電路。 在具有上述方式之構造之攝影裝置中，在亮度信號微 分電路1 1 0 8取得亮度信號之微分値，抽出亮度信號之 高頻成分，利用高頻成分計數器1 109計數涵蓋1個框 架之影像信號所含之一定値以上之高頻成分。假如該 高頻成分之數目變少時，成爲未對焦之狀態，亦即非聚 焦狀態。 其中，在非聚焦狀態檢測電路1 1 1 0，當計數到之高頻 -29- 515207 五、發明説明（28) 成分之數目在臨限値以下之情況時，就作爲檢測到非聚 焦狀態。 只有在非聚焦狀態檢測電路111 〇檢測到非聚焦狀態 之情況時，才在下一個框架將色再現範圍記憶在色再現 範圍記憶電路11 0 5。在不是非聚焦狀態之情況，亦即在 聚焦之情況，不更新非聚焦狀態所記憶之色再現範圍， 保持原來記憶。 另外，檢測非聚焦狀態之方法是利用攝影裝置之自動 聚焦功能之方法。攝影裝置之自動聚焦方式習知的有 所謂之登山方式，抽出得自攝影元件之影像信號中之高 頻成分，以使該高頻成分成爲最大之方式驅動透鏡用來 調整焦點。 在此種方法中，利用亮度信號微分電路1 1 0 8取得亮 度信號之微分値，用來抽出亮度信號之高頻成分，以高 頻成分計數器1 1 〇 9計數影像信號所含之一定値以上之 高頻成分。影像信號之高頻成分在透鏡爲聚焦狀態時 成爲最大，隨著遠離聚焦位置而變小。因此，在高頻計 數器1109之計數爲最大之位置就成爲聚焦位置。 其中，當高頻成分計數器之計數進行大變化之情況時， 非聚焦狀態檢測電路1 1 1 0就判斷爲非聚焦狀態，將這 時之色再現範圍記憶在色再現範圍記憶電路1 1 0 5。 另外，在非聚焦狀態檢測電路1 1 1 0,亦可以在利用透 鏡驅動電路Π 1 1使透鏡移動之情況時判斷爲非聚焦狀 -30- 515207 五、發明説明（29) 態，記憶其色再現範圍。 在此種方式之本實施例中，利用現在攝影之圖像用來 記憶色再現範圍，可以省略預先檢查攝影裝置之色再現 範圍之步驟。另外，經由對亮度，色信號進行平滑化將 其記憶在色再現範圍，或記憶非聚焦時之色再現範圍， 可以用來記憶未含有僞色之正確之色再現範圍。經由 記憶正確之色再現範圍，可以降低僞色藉以提高亮度邊 緣部之畫質。 另外，區域之分割是在第7圖中在各個軸方向分別分 割成8個，全體分割成爲512個，檢查其圖素之分布，但 是分割之數目並不只限此種方式。另外，記憶色再現範 圍之處理亦可以是不對每一個框架進行，而是每一定時 間進行，亦可以只有攝影圖像有變化時才進行記憶。 (實施例3 ) 下面將參照圖面用來說明與本發明之申請專利範圍 第9項，第10項，第1 1項，第12項，和第13項之相當之 攝影裝置作爲實施例3。 第6圖是方塊圖，用來表示本實施例3之攝影裝置。

[Best Embodiment for Carrying Out the Invention] (Embodiment 1) The following describes a photographing device equivalent to item 1, item 2, and item 3 of the scope of patent application of the present invention as Example 1 with reference to drawings ° Fig. 1 is a block diagram showing the structure of the photographing apparatus of the first embodiment. In the first figure, reference numeral 101 is an imaging element, 102 is an A / D converter, 103 is a perception signal calculation circuit, 104 is a color signal calculation circuit, 105 is a color reproduction range memory circuit, and 106 is a pseudo Color determination circuit, 107 is a false color suppression circuit. -20- 515207 V. Description of the invention (19) The signal processing operation of the photographing device having the structure described above will be described below. The image signal captured by the imaging element 101 is digitized by the A / D converter 102, and the brightness signal calculation circuit 103 and the color signal calculation circuit 104 are used to calculate the brightness and color signals. The color signal calculation method in the color signal calculation circuit 104, as shown in the conventional example, calculates a signal corresponding to (RY) on the odd (N) line, and calculates a signal equivalent to (BY) on the even (N + 1) line. signal. N line (Ye + Mg)-(Cy + G) = 2R-G. &Quot; (l) N + 1 line (Cy + Mg)-(Ye + G) = 2B-G ... (2) Luminance signal The calculation of the luminance signal of the calculation circuit 1 03 is performed by adding and averaging the area shown in the area 1 in FIG. 30. In this case, the luminance signal Y is calculated in the following manner. Y = Ye + Mg + Cy + G = 2R + 3G + 2B ... (3) The color reproduction range memory circuit 105 stores the color reproduction range of the photographing device in advance. In the case where all the objects are photographed with the photographic device in a state where no false colors have occurred, the photographed colors become a color distribution within a limited range shown in FIG. 2. That is, it becomes the color reproduction range of the photographic device. Fig. 2 shows the color reproduction range in the three dimensionality of the luminance signal Y, the color signals (R-Y), and (B-Y). The false color is a color generated due to improper color signal processing as described in the conventional technology, so the false color appears in a region outside the color reproduction range that the photographing device shown in FIG. 2 could originally express. Therefore, according to whether the color processed by the signal is within the color reproduction range, -21- 5. Invention Description (2G) can be used to determine whether the color is a false color. The color reproduction range memory circuit 105 stores in advance the range of colors that can be represented by various image samples taken by the photographing device. Because the color reproduction range is the third dimension data of brightness Y and color (RY), (BY), a three-dimensional memory is set, and the input data Y, (RY), (BY) is used as the address. When it is within the color reproduction range, for example, the color reproduction range memory circuit 1 0 5 stores 1 and when it is outside the color reproduction range, it stores 0 0 and then fetches the input signal, and the brightness signal calculation circuit 103 calculates the brightness signal. The color signal calculation circuit 105 calculates a color signal. The luminance signal and color signal calculated by the false color determination circuit 106 are compared with the color reproduction range data stored in the color reproduction range memory circuit 105 to determine whether the input data is a false color. Even if the luminance signal data and color signal data refer to the address of the color reproduction range memory circuit, when the memory range is 1, it is not a false color because it is within the color reproduction range. When the memory range is 0, Because it is outside the color reproduction range, it is determined as a false color. When the pseudo-color suppression circuit 107 determines that the pseudo-color determination circuit 106 is a pseudo-color, the pseudo-color suppression processing is performed. The suppression of the pseudo color is achieved by reducing or reducing the gain of the color. By using this processing, the gain of the color of the input signal is reduced, which can be used to suppress false colors. When it is determined not to be a false color, the gain of the color is set to 1, and the color signal is directly passed without suppressing the false color. In this way, in the photographing device of the first embodiment, pre-check -22-515207. V. Description of the invention (21) Check the color reproduction range of the photographic device and store it in the color reproduction range. Recording circuit 1005, according to This data is used to determine whether the input data calculated by the luminance signal calculation circuit and the color signal calculation circuit is within the color reproduction range, so as to determine whether it is a false color, and when it is determined as a false color, the false color suppression is performed correctly. To suppress false colors. In addition, when the color reproduction range is stored in the color reproduction memory circuit 105, it is necessary to perform photography under the condition that no false color is generated to memorize the color reproduction range. This can be achieved by making the focus of the optical system of the photographing device. It is shifted and the color reproduction range is memorized. That is, because the false color will occur at a position on the edge of the brightness, the focus is intentionally shifted to make the edge information of the degree null, so that the false color does not occur. The color reproduction range of the state in which the false color does not occur in the memory can be used for highly accurate suppression of the false color. In addition, the realization of another method of memorizing the color reproduction range can previously memorize the data after smoothing the luminance signal and the color signal separately. That is, since the false color occurs at a position on the edge of the brightness, smoothing can make the color of the edge portion disappear. In the following, FIGS. 3, 4 and 5 are used to explain the memory method of the color reproduction range in this case. Fig. 3 is a block diagram of a signal smoothing circuit in the memory color reproduction range. In Fig. 3, reference numeral 306 is a luminance signal smoothing circuit, and 307 is a color signal smoothing circuit. The luminance signal and the color signal are smoothed separately to suppress the false color, and the color reproduction range memory color circuit is stored in the color reproduction range memory circuit 305. -23- 515207 V. Description of the invention (22) The smoothing method will be described below. For example, when photographing an object having a white (W) area and a black (BK) area next to each other, the arrangement of the signal-processed pixels becomes as shown in FIG. 4. In Figure 4, a false color occurs in the realm. The false color that occurs in this case is purple (Mg). The magnitude of the (R-Y) signal in this case is shown in Figure 5 (a). When the signal's frame is 8-bit data, (R-Y) becomes a frame from 0 to 2 5 5 and in achromatic (that is, black) images, the frame of (R-Y) becomes 128. Therefore, since the left side of the original boundary part was white and the right side was black, the entire part of the (R-Y) signal became 1 2 8 but the part of the realm part for false color became a magenta part 2 3 4. Among them, smoothing the (R-Y) signal is used to perform false color correction. There are various methods of smoothing. For example, you can use „bit.over__. Smoothing. The median filter is in the area that contains the 丽 prime, with the size of 値 as the center pixel as the attention pixel. For example, for the attention pixel of FIG. 5 (a), when central filtering is applied to area 1, because the center of the pixel is 128, the pixel of the attention pixel becomes 128. In this way, the median filtering is performed sequentially. At this time, the processing result becomes as shown in Figure 5 (b), and the false color has been removed. Similarly, the brightness signal is also smoothed (BY). Because this smoothing process can suppress the false color, Therefore, the color reproduction range without false colors can be stored in the color reproduction range recording circuit. In addition, the filter arrangement of the photographic element and the brightness signal, the calculation method of the color signal is not limited to the above, as long as the filter arrangement is a single plate type -24- 515207 Description of the Five 'Invention (23) · Any kind of arrangement can be used, the luminance signal, and the color signal can also be processed by the signal suitable for its filter arrangement. (Embodiment 2) Reference will be made to Figs. 11 _ Let's explain the photographic device equivalent to items 4, 5, 6, 7, and 8 of the scope of patent application of the present invention as Embodiment 2. Fig. 6 is a block diagram showing the implementation Structure of the photographing device of Example 2. In Fig. 6, reference numeral 601 is a photographing element, 602 is an A / D converter, 603 is a luminance signal calculation circuit, 604 is a color signal calculation circuit, and 605 is a color reproduction range memory. Circuit, 6 〇 6 is a false color judging circuit, and 607 is a false color suppressing circuit. Embodiment 2 does not store the color reproduction range in the color reproduction range memory circuit in advance as in Embodiment 1, but stores a frame. The color reproduction range of the previous input data. That is, it takes a lot of time and man-hours to remember all the color reproduction ranges of the 100 million photography devices in advance. Therefore, by not performing this operation, the color reproduction ranges of the images taken now are memorized. The color reproduction range can be more easily memorized. The signal processing operation of the photographing device having the structure described above will be described below. The video signal photographed by the photographing element 60 1 is digitized by the A / D converter 602 and then Output to the luminance signal calculation circuit 603 and the color signal calculation circuit 604. The luminance signal calculated by the luminance signal calculation circuit 603 is sent to the color reproduction range register circuit 605 and the false color -25-515207. 5. Description of the invention (24) Judgment The circuit 606, and the color signal calculated by the color signal calculation circuit 604 is sent to the color reproduction range memory circuit 605, the false color determination circuit 606, and the false color suppression circuit 607. The brightness signal and color The calculation method of the signal is the same as that of the embodiment 1, so its description is omitted here. The steps of the method of memorizing the color reproduction range are to first store the color of the photographing device covering a frame in the color reproduction range memory circuit 60 in FIG. 6. The reproduction range is suppressed from false color according to the memorized color reproduction range from the next frame, and the color reproduction range of the frame is stored in the color reproduction range recording circuit 605. Figure 7 divides the input signal in three dimensions of luminance Y, color (R-Y), and (B-Y). In the color reproduction range memory circuit 605, as shown in FIG. 7, the three-dimensional data of the brightness and color signals are divided into a plurality of regions. When the input data is each divided region, this region is used as the color reproduction range. Memory. The memory method of the color reproduction range will be described below using FIG. Figure 8 shows the color distribution of one frame, and the results are projected on the Y, (R-Y) axis. The original color reproduction range is three-dimensional data of Y, (RY), (BY), but to simplify the description, it is transformed into two-dimensional data projected on the Y, (R-Y) axis, which is used to explain Memory method of color reproduction range. Fig. 8 (a) shows the color distribution of one frame part actually photographed. It is divided into Y in the Y-axis direction and divided into 12 regions in the (R-Y) -axis direction. Check the distribution of the pixels in each area. -26- V. Description of the invention (25) When there are pixels in the area, as shown by the diagonal line in Figure 8 (b), remember them as color This area of the reproduction range. In this way, the shaded area in Fig. 8 (b) is used as the memory of the color reproduction range, and the area other than the shaded area is used as the memory outside the color reproduction range. The case described above is the case of projecting 3-dimensional data onto 2-dimensional data, and dividing the area shown in Fig. 7 into 3-dimensional areas. When there are pixels in the area, the area is reproduced as a color. For example, when the memory stores 1 and there are no pixels in the area, the area is stored outside the color reproduction range and is stored in the range 0. In addition, the false color judging circuit 6 06 checks whether the input signal belongs to the divided area in FIG. 7 and the reference color reproduction range memory circuit 6 0 5 is used to determine whether the area is in the color reproduction range. When it is 1, because it is a color in the color reproduction range, it is judged as a non-pseudo color. If the memorized 値 is 0, it is determined as a pseudo color. In the pseudo-color suppression circuit 607, when the pseudo-color determination circuit 6 0 6 determines that it is a pseudo-color, the pseudo-color suppression processing is performed. The suppression of the false color is carried out so that the gain of the color is reduced or becomes zero. When it is judged that it is not a false color, the gain of the color is set to 1, and the color signal is directly passed without suppressing the false color. In addition, when the three-dimensional data of the color signal is divided into a plurality of regions, instead of being divided into equal regions as shown in FIG. 7, the brightness and color signals are divided into the vicinity of the boundary between the color reproduction range and the false color. The 3D data is divided into thinner areas, and the other areas are divided into thicker areas. When there is input data in the divided area, the area is used as -27-515207. 5. Description of the invention (26) Color reproduction The scope is memorized. Because the area with low chroma must be within the color reproduction range, the area is coarsely divided. In addition, in the area with high chroma, coarse division is performed for areas with a high probability outside the color reproduction range. The middle and other areas are divided into fine areas, and the memory color reproduction range can be used to accurately check the color reproduction range. Fig. 9 is a sample projecting the same color reproduction range as in Fig. 8 on the Y, (R-Y) axis, and divided into thinner areas near the boundary between the color reproduction range and the false color. The number of divisions in Figure 8 and Figure 9 is the same, but in Figure 9, the finer color reproduction range can be checked. In Fig. 9, the division method is changed on the (R-Y) axis, but the same process can be performed on the (B-Y) axis. By performing coarse segmentation in areas with very low and high chroma, and fine segmentation in areas other than it, it can be used to more accurately check the color reproduction range. In addition, when the color reproduction range is memorized to the color reproduction memory circuit 60 5, it is necessary to memorize the color reproduction range for photographing under the condition that false colors do not occur. However, as described in Embodiment 1, it is also possible to memorize the luminance signal. And color signals are smoothed separately. That is to say, the false color occurs at a certain position of the edge, so the color of the edge portion is made useless by smoothing. The block diagram of this case is shown in Figure 10. In Figure 10, the reference number 1001 is a photographic element, 1002 is an A / D converter, 1003 is a degree signal calculation circuit, 1004 is a color signal calculation circuit, and 1005 is a color reproduction range memory circuit. 1,006 is a false color determination circuit, 1007 is a false color suppression circuit, 1008 is a luminance signal smoothing circuit, and 009 is a color signal smoothing circuit. -28- V. Description of the invention (27) According to the method described above, the brightness signal and color signal smoothing circuit 1 0 0 8 and the color signal smoothing circuit 1 0 9 are added, and the brightness and color signals are subjected to median filtering and other methods. The smoothing process stores the color reproduction range after removing the false color in the color reproduction range memory circuit 105, which can memorize the correct color reproduction range that does not include the false color. In addition, as shown in FIG. 11, another method for shooting under the condition that no false color occurs can memorize the color reproduction range in the non-focusing state of the photographing device. In the unfocused state, since there is no edge of brightness, no false color occurs, and the correct color reproduction range can be memorized. Fig. 11 is a block diagram showing the structure of a photographing apparatus having a photographing apparatus in a non-focus state. In FIG. 11, reference numeral 1 101 is a photographing element, 1 102 is an A / D converter, 1103 is a luminance signal calculation circuit, 1104 is a color signal calculation circuit, 1 1 05 is a color reproduction range memory circuit, and 11 0 6 is a false color determination circuit, 1 1 07 is a false color suppression circuit, 1 108 is a luminance signal differentiation circuit, 1 1 09 is a high-frequency component counter, 1 1 1 0 is a non-focus state detection circuit, 1 1 1 1 is a lens driving circuit. In the photographing device having the structure described above, the differential signal of the luminance signal is obtained in the luminance signal differentiation circuit 1 108, and the high-frequency component of the luminance signal is extracted, and the high-frequency component counter 1 109 is used to count the image signals covering one frame. Contains certain high frequency components above 値. If the number of the high-frequency components is reduced, it becomes an unfocused state, that is, a non-focused state. Among them, in the out-of-focus state detection circuit 1 1 1 0, when the counted high frequency is -29- 515207 V. Description of the invention (28) When the number of components is below the threshold, the non-focus state is detected. Only when a non-focus state is detected by the non-focus state detection circuit 111 0, the color reproduction range is stored in the color reproduction range memory circuit 11 0 5 in the next frame. When it is not in the unfocused state, that is, when it is in focus, the color reproduction range stored in the unfocused state is not updated, and the original memory is maintained. In addition, the method of detecting the out-of-focus state is a method using the auto-focus function of the photographing device. The auto-focusing method of the photographing device is known as the so-called mountaineering method, which extracts the high-frequency components in the image signal obtained from the imaging element, and drives the lens to adjust the focus so that the high-frequency components become maximum. In this method, the luminance signal differential circuit 1 108 is used to obtain the differential signal of the luminance signal, which is used to extract the high-frequency component of the luminance signal, and the high-frequency component counter 1 1 09 is used to count a certain signal contained in the image signal. High-frequency components. The high-frequency component of the video signal becomes maximum when the lens is in focus, and becomes smaller as it moves away from the focus position. Therefore, the position where the count of the high-frequency counter 1109 becomes the maximum becomes the focus position. Among them, when the count of the high-frequency component counter changes greatly, the non-focus state detection circuit 1 1 1 0 judges it to be the non-focus state, and the color reproduction range at this time is stored in the color reproduction range memory circuit 1 105. In addition, in the non-focus state detection circuit 1 1 1 0, it can also be judged to be non-focused when the lens driving circuit Π 1 1 is used to move the lens. -30-515207 V. Description of the invention (29) State, memorize its color Reproduction range. In this embodiment of the method, the image captured now is used to memorize the color reproduction range, and the step of checking the color reproduction range of the photographing device in advance can be omitted. In addition, the brightness and color signals are smoothed to memorize them in the color reproduction range, or memorize the color reproduction range when not in focus, which can be used to memorize the correct color reproduction range without false colors. By memorizing the correct color reproduction range, the false color can be reduced to improve the image quality at the edge of the brightness. In addition, the area is divided into 8 in each axis direction in Fig. 7 and the whole is divided into 512. The distribution of pixels is checked, but the number of divisions is not limited to this method. In addition, the processing of the memory color reproduction range may not be performed for each frame, but every time, or it may be memorized only when there is a change in the photographic image. (Embodiment 3) The following will describe a photographing device equivalent to item 9, item 10, item 11, item 12, and item 13 corresponding to the scope of patent application of the present invention with reference to the drawings as example 3. . Fig. 6 is a block diagram showing the photographing apparatus of the third embodiment. Since the structure is the same as that of the second embodiment, its description is omitted here. The basic operation of the photographing device of the third embodiment is the same as that of the second embodiment described above, but the method of memorizing the color reproduction range is different. In the second embodiment described above, the color reproduction range before one frame is checked -31- ^ 207 A7 B7 Printed by the Consumer Cooperatives of the Intellectual Property Bureau of the Ministry of Economic Affairs The reproduction range memory circuit 605, however, in this embodiment 3, is a memory color reproduction range in order with time. First, the color reproduction range of the color reproduction range memory circuit 605 is stored in a frame part. When the data of the next frame is input, in addition to maintaining the previously reproduced color reproduction range, the newly distributed area is also stored as the color. Reproduction range. Based on the memorized color reproduction range, the false color determination circuit 606 determines whether the input data is a false color, and when it is determined as a false color, the false color suppression circuit 607 performs false color suppression. In addition, when the third-dimensional data of luminance and color signals are divided into a plurality of regions, as shown in the second embodiment, the regions are not divided equally, but as shown in the example in FIG. Near the realm of color, the three-dimensional data of brightness and color signals are divided into thin areas, and the other areas are divided into thick areas. When there is input data in the divided area, the area is memorized as the color reproduction range. When the color reproduction range is memorized to the color reproduction memory circuit 60 5, it is necessary to memorize a color reproduction range that does not contain a false color, but as shown in FIG. 10, the brightness signal and the color signal can be smoothed separately and sequentially. Smoothed data. In this way, the correct color reproduction range without false colors can be memorized, and the color reproduction range over time can be calculated more accurately. In addition, as shown in FIG. 11, another method of memorizing a color reproduction range that does not contain a false color in a color reproduction memory circuit can sequentially store the color reproduction ranges in an unfocused and unfocused state of the photographing device.

Description of the invention (3) Because there is no bright edge in the focus state, false colors will not occur, and the correct color reproduction range can be memorized. The differential signal of the luminance signal is obtained in the luminance signal differentiating circuit 1108, which is used to extract the high-frequency components of the luminance signal. The high-frequency component counter 1109 is used to count the high-frequency components of the image signal that are higher than a certain frequency.

The figure 12 is a block diagram, The structure of the photographing device of the fourth embodiment will be described. In Fig. 12, reference numeral 1201 denotes a photographing element, 1 2 02 denotes an A / D converter, 1 2 0 3 denotes a luminance signal calculation circuit, 1 2 04 denotes a color signal calculation circuit, and 1 2 0 5 denotes a color reproduction range memory.

The basic operation of the photographing device of this embodiment 4 is the same as that of the above embodiments 2, 3, but the different part is that when the color reproduction range is memorized, the edge detection circuit 1 20 8 is used to detect the edges of brightness. At this time, the color is stored in the color reproduction range memory circuit 1250. As shown in conventional techniques, false colors occur at the edges of brightness. Therefore, there is a high possibility that the color at the position of the edge of the brightness becomes a false color, so this color is not memorized in the color reproduction range memory circuit 125. That is, when the color reproduction range is memorized in the color reproduction range memory circuit 125, the edge detection circuit 1208 is used to detect the edge of brightness, and when there is a brightness edge, the color is not stored in the color reproduction range memory circuit. -34- This paper size is applicable to Chinese National Standard (CNS) A4 (210 x 297 mm) Please read the notes on the back first

Description of Invention () 1 2 0 5 In this way, the color reproduction range memory circuit 1 205 memorizes the color reproduction range of one frame portion, or the color reproduction range of a plurality of frame portions that have been added to the color reproduction range over time. The memory of the color reproduction range is divided into three dimensions as shown in Figure 7. When there are pixels in the area, the area is used as the color reproduction range. For example, 1 is stored in the memory. When there are no pixels in the image, the area is used as the color reproduction range and the memory is 0. In the false color judging circuit 1 20 6, check whether the input signal belongs to any one of the divided areas in FIG. 7 and the color reproduction range record _ circuit 1 205 refers to whether the area is in the color reproduction range. If the memory is 1 At this time, because the color is within the color reproduction range, it is determined not to be a false color. If the memorized frame is 0, it is determined to be a false color. In the false color suppression circuit 1 20 7, when the false color determination circuit 1 206 determines that it is a false color, the suppression processing of the false color is performed. The suppression of the false color is to reduce the color gain or to zero. When it is determined that it is not a false color, the gain is set to 1, and the color signal is directly passed without suppressing the false color. In addition, when the third-dimensional data of luminance and color signals are divided into multiple regions, instead of equally dividing the regions, the third-dimensional data of luminance and color signals may be near the boundary of color reproduction range and false colors.

If the color signal distribution of one frame part is as shown in Fig. 15, the number of pixels in each area from BO 1 to B64 is calculated in the manner shown in Fig. 16. In Figure 15, area 1 and area 2 surrounded by circles are areas where false colors occur. As can be understood from Fig. 16, the number of pixels in this area is smaller than that in the color reproduction range. That is, there is a high possibility that the color of a region with a small number of pixels becomes a false color, or the boundary between the false color and the color reproduction range. Therefore, check the number of pixels in each area, according to the number of pixels, such as the first 7 -37- 515207 $ 9 18 amended cattle less: N, make up five, the description of the invention (36) As shown in the figure, In many cases, the color gain is set to 1, and color suppression is not performed. When the number of pixels is small, it is determined that a false color occurs. The smaller the number of pixels, the smaller the color gain is. Suppressed. For example, the gain is calculated from a color signal. (Gain) = (Number of pixels in each area) / 200 where (Gain) = 1 in the case of (Gain)> 1. When the gain of each area is calculated in this way, the gain of each area becomes as shown in Fig. 18. The calculated gain of each area is stored in the pseudo-color suppression amount memory circuit 138. After memorizing the pseudo-color suppression amount covering a frame part, the input signal is subjected to a pseudo-color suppression process. The area determination circuit 1 3 0 9 is used to determine whether the color data output from the color signal calculation circuit 1 3 04 belongs to the divided area BO 1 to B64. The area is called from the false color suppression amount memory circuit 1 3 0 8 For the pseudo-color suppression, according to the suppression amount, the pseudo-color suppression circuit 133 is used to change the gain of the color signal to suppress the false color. In addition, when calculating the color gain, it divides the number of pixels in each area by 2 0 0, but it is not limited to this value. When the amount of false color suppression is large, a value greater than 2 0 can be used, instead In the case of a small amount of false color suppression: less than 2 0 0 can be used. However, the gain becomes 1 when the number of pixels in each area is larger than this unit. The color signal is divided into regions to calculate the false color suppression amount of each region. When the false color suppression amount is memorized, it is necessary to use a signal that does not contain the false color to calculate the false color suppression amount and memorize it. As shown in the figure 19, you can also remember the information after smoothing the luminance signal and the color signal -38- 515207 A7 — ____B7____ _ 37 V. Description of the invention ().

In addition, another method of using a signal that does not contain a false color to memorize the suppression amount of the false color is to memorize the suppression amount of the false color as shown in FIG. 20 when the imaging device is out of focus and out of focus.

Description of the invention (3 9) Increase the amount of false color suppression in this area, so that the processing of false color pressure in the boundary area will not become discontinuous, and the false color can be suppressed correctly. (Embodiment 6) Hereinafter, a photographing device corresponding to item 20 of the patent application scope of the present invention and equivalent to item 21 will be described as embodiment 6 with reference to FIG. 21. Fig. 21 is a block diagram showing the structure of a photographing apparatus of Embodiment 61. In Fig. 21, reference numeral 2101 is a photographing element, 2102 is an A / D converter, 2103 is a luminance signal calculation circuit, 2104 is a color signal calculation circuit, 2 105 is a region division circuit, and 2 106 is each area. Pixel prime counter, 2 107 is a false color suppression amount calculation circuit, 2 108 is a false color suppression amount memory circuit, 2 1 0 9 is a region judgment circuit, 2 1 1 0 is a false color suppression circuit, 2 1 1 1 is an edge detection circuit. The basic operation of the photographing device of the sixth embodiment having the above-mentioned structure is substantially the same as that of the fifth embodiment, but the different part is that when counting the number of pixels in each area after the area is divided, In this case, the color is not counted. Since the edge portion of the brightness may cause false color in most cases, the color of the edge portion of the brightness is not counted to improve the accuracy of suppressing the false color. Therefore, the edge detection circuit 2 1 11 is used to detect the edge of brightness. When there is an edge, the pixel number counter 2 1 0 of each area is not counted, and the pixel count is performed only when there is no edge. . In this way, according to the number of pixels in each area counted, the pseudo-color suppression amount calculation circuit is used to calculate the pseudo-color suppression amount, and the pseudo-color suppression amount is stored in the pseudo-color suppression amount memory circuit 2 1 0 8. -41- 515207 A7 B7 V. Explanation of the invention () Secondly, according to the false color suppression amount of the false color suppression circuit 2 1 0 8 which is recorded in 100 million, the false color suppression circuit 2 1 1 0 is used for color matching. The signal undergoes false color suppression. In addition, the false color suppression amount memory circuit 2 108 can also store the average value of the false color suppression amount calculated by covering multiple frames. By averaging the false color suppression amount, the false color suppression amount can be calculated more accurately, and the dispersion of the color due to the change of the false color suppression amount in each frame can be prevented. In this embodiment of the sixth embodiment, only the color reproduction range is memorized with the color signal, which can reduce the memory capacity. In addition, the boundary between the false color and the color reproduction range does not cause discontinuities in the false color suppression process. Moreover, it is not necessary to use the color at the edge of the brightness to calculate the false color suppression amount, so the accuracy of the false color suppression can be improved.

Description of the invention (41) circuit, 2211 is a pseudo-color suppression circuit, and 2212 is a hue rotation circuit. The operation of the photographing apparatus having the structure described above will be described below. False colors occur in all colors, but most of the cases become stronger in the magenta and green directions, and are very significant. In Example 7, the colors in the magenta and green axis directions were subjected to pseudo-color processing. Divide the colors in the purple, red, and green directions into each area, check the number of pixels, calculate the amount of false color suppression for each area, and perform false color suppression. The magenta, green axis is shown in Fig. 23 (a), and it is about 60 degrees away from the (B-Y) axis A. Therefore, as shown in Fig. 23 (b), when the pseudo-color suppression process is performed, Hue rotation of about 60 degrees is used to make the purple-red and green axes coincide with (B-Y), which can be used to simplify processing. Therefore, the hue rotation circuit 2 2 10 rotates the hue. When rotating the hue by 60 degrees, for the input data (R_Y), (BY) calculation formulas (4), (5), the color data (R, Y), "BY" after rotation can be obtained. (RY ),-Cos (60 °) * (RY) -Sin (60 °) * (BY) ... (4) (BY), = Sin (60). * (RY) -Cos (60.) * ( Β-Υ) .. (5) Since the colors in the purple and green directions are distributed on the (B_Y) axis through rotation, the suppression of false colors can be performed only on the (B-Y) axis. First, The area dividing circuit 2205 is used to divide only the area on the (BY) axis. This area is divided as shown in FIG. 24. For example, the area from -20 to 20 on the (R_γ) axis is divided into (B_γ ) The axis is divided into 8 regions from B0 to B08. In each segmented region, the pixel number of each region is used to measure the purple and red of the i frame part and the green direction is -43-

Description of the invention () The number of pixels in the color. The counting results are shown in Figure 25. Please read the notes on the back first and then fill out this page. Using the number of pixels in each area counted, the false color suppression amount calculation circuit 2207 calculates the false color suppression amount of each area. The realization of false color suppression can make the gain of the color signal small or 0. When the number of pixels in the area is large, it is used as the color reproduction range without directly reducing the gain. The pixels in the area are directly output. When the number is small, the color gain is reduced as the false color, or the color reproduction range and the boundary of the false color, and the false color suppression is performed. For example, let the gain of the color signal be (gain) = (number of pixels per area) / 200 to calculate the false color suppression amount. However, in the case of (gain)> 1, (gain) = 1 is formed. When the gain of each area is calculated in this way, it becomes as shown in Figure 26. The calculated gain of each area is stored in the false color suppression amount recording circuit 2208. Printed by the Consumer Cooperative of the Intellectual Property Bureau of the Ministry of Economic Affairs. After memorizing the amount of false color suppression that covers one frame part, the signal input in the next frame is processed for false color suppression. The hue rotation circuit 2210 is used to rotate the color data output from the color signal calculation circuit 2204, and the area determination circuit 2 2 0 9 is used to determine which one of the divided areas B01 to B08 belongs. From the pseudo color suppression amount memory circuit The amount of false color suppression in the area is called in 2 0 8. According to the suppression amount, the false color suppression circuit 2 2 11 is used to change the gain of the color signal to suppress the false color. Then, the hue rotation circuit 2 2 1 2 is used, and at this time, it is rotated by -60 ° in the opposite direction, and is used to convert to the original hue. The above explained is that when calculating the color gain, the number of pixels in each area is divided by 2 0 to calculate, but it is not limited to this.

V. Description of the invention () When the amount of color suppression becomes large, you can use a value greater than 200. Instead, you want to suppress When the pressure becomes small, less than 200 can be used. However, when the number of pixels in each region is larger than this value, the gain is set to 1. In addition, the color signal is divided into each region, and the pseudo-color suppression amount of each region is calculated. When the pseudo-color suppression amount is memorized, in order to prevent the calculation of the pseudo-color suppression amount from the signal containing the pseudo color, Therefore, as shown in FIG. 27, the pseudo-color suppression amount is calculated from the data after the color signal is smoothed, so as to memorize the pseudo-color suppression amount.
