現有的影像色彩精準度調校技術已應用於筆記型電腦及電腦螢幕上。然而，受出廠時校調儀器不同的影響（例如，儀器誤差及/或頻譜的不同），同樣標榜∆E>1的兩個顯示器可能有不一致的色彩表現。並且，若使用者對於色彩空間（如Adobe RGB、sRGB、DCI-P3等）不甚熟悉，可能不知如何藉由調配色彩設定以使兩個顯示器有一致的色彩表現。對於專業繪圖者或需色彩高精準度顯示器的使用者而言，兩個顯示器之間的些微色差可能會影響其對色彩的判別結果。The existing image color accuracy adjustment technology has been applied to notebook computers and computer screens. However, due to the influence of different calibration instruments at the factory (for example, instrument error and/or different spectrum), two monitors that also claim ∆E>1 may have inconsistent color performance. Moreover, if users are not familiar with color spaces (such as Adobe RGB, sRGB, DCI-P3, etc.), they may not know how to adjust color settings to make two displays have consistent color performance. For professional graphic artists or users who require high-precision color displays, the slight color difference between the two displays may affect their color discrimination results.

In different embodiments, the electronic device 110 is, for example, a notebook computer or other device that can be connected to the external display 120 through a display port (DP) or HDMI interface to use the external display 120 as a mirror screen or an extension screen. , But not limited to this. For ease of description, the following assumes that the electronic device 110 is a notebook computer, but it is not used to limit the possible implementations of the present invention.

如圖1所示，電子裝置100包括儲存電路112及處理器114。儲存電路112例如是任意型式的固定式或可移動式隨機存取記憶體（Random Access Memory，RAM）、唯讀記憶體（Read-Only Memory，ROM）、快閃記憶體（Flash memory）、硬碟或其他類似裝置或這些裝置的組合，而可用以記錄多個程式碼或模組。As shown in FIG. 1, the electronic device 100 includes a storage circuit 112 and a processor 114.

The details are described below.

請參照圖2，其是依據本發明之一實施例繪示的色彩調校方法流程圖。本實施例的方法可由圖1的電子裝置110執行，以下即搭配圖1所示的元件說明圖2各步驟的細節。Please refer to FIG. 2, which is a flowchart of a color adjustment method according to an embodiment of the present invention. The method of this embodiment can be executed by the electronic device 110 of FIG.

首先，在步驟S210中，處理器114可取得外部顯示器120的多個第一色座標（例如是外部顯示器120的R、G、B色座標）及第一白平衡參數。在不同的實施例中，處理器114可透過不同的方式來取得上述第一色座標及第一白平衡參數。First, in step S210, the processor 114 may obtain a plurality of first color coordinates of the external display 120 (for example, the R, G, and B color coordinates of the external display 120) and a first white balance parameter. In different embodiments, the processor 114 may obtain the above-mentioned first color coordinates and the first white balance parameters through different methods.

具體而言，在現有技術中，顯示器製造商一般會在其所製造的顯示器個別的延伸顯示能力識別資料（Extended display identification data，EDID）中寫入R、G、B色座標及白平衡參數。Specifically, in the prior art, display manufacturers generally write R, G, B color coordinates and white balance parameters in the extended display identification data (EDID) of the individual displays they manufacture.

然而，僅有部分的顯示器製造商（下稱第一類製造商）會在對其所產製的顯示器個別進行量測之後，將所測得的具體R、G、B色座標及白平衡參數寫入各顯示器的EDID中。其餘的顯示器製造商（下稱第二類製造商）多半僅是將一批顯示器的平均R、G、B色座標及白平衡參數寫入顯示器的EDID中。換言之，在第一類製造商製造的各顯示器中，EDID所記錄的R、G、B色座標及白平衡參數較為準確。相對地，在第二類製造商製造的各顯示器中，EDID所記錄的R、G、B色座標及白平衡參數較為不準確。However, only some display manufacturers (hereinafter referred to as the first type of manufacturers) will measure the specific R, G, B color coordinates and white balance parameters of the monitors they produce. Write in the EDID of each display. The rest of the display manufacturers (hereinafter referred to as the second type of manufacturers) mostly just write the average R, G, B color coordinates and white balance parameters of a batch of displays into the EDID of the display. In other words, the R, G, B color coordinates and white balance parameters recorded by EDID are more accurate in each display manufactured by the first type of manufacturer. In contrast, the R, G, B color coordinates and white balance parameters recorded by EDID are relatively inaccurate in each display manufactured by the second type of manufacturer.

在一實施例中，設計者可將第一類製造商所製造的顯示器型號記錄於一預設資料庫中，以供後續查找。In one embodiment, the designer can record the display model manufactured by the first-type manufacturer in a preset database for subsequent search.

基此，處理器114在執行步驟S210時，可先取得外部顯示器120的顯示器型號，並判斷此顯示器型號是否已記錄於上述預設資料庫中。若上述顯示器型號已記錄於預設資料庫中，即代表外部顯示器120係由上述第一類製造商所製造。換言之，外部顯示器120的EDID中記錄的R、G、B色座標及白平衡參數較為準確。因此，處理器114即可直接讀取外部顯示器120的EDID以取得外部顯示器120的上述第一色座標及第一白平衡參數。Based on this, when the processor 114 executes step S210, it can first obtain the display model of the external display 120, and determine whether the display model has been recorded in the aforementioned preset database. If the above-mentioned display model has been recorded in the default database, it means that the external display 120 is manufactured by the above-mentioned first-type manufacturer. In other words, the R, G, B color coordinates and white balance parameters recorded in the EDID of the external display 120 are more accurate. Therefore, the processor 114 can directly read the EDID of the external display 120 to obtain the first color coordinates and the first white balance parameters of the external display 120.

另一方面，若上述顯示器型號未記錄於預設資料庫中，即代表外部顯示器120可能並非由上述第一類製造商所製造。換言之，外部顯示器120的EDID中記錄的R、G、B色座標及白平衡參數較為不準確。在此情況下，處理器114例如可顯示一提示訊息，以提示使用者可藉由將校色器連接至電子裝置110來對外部顯示器120進行量測，以較為準確地取得外部顯示器120的上述第一色座標及第一白平衡參數。On the other hand, if the above-mentioned display model is not recorded in the preset database, it means that the external display 120 may not be manufactured by the above-mentioned first-type manufacturer. In other words, the R, G, B color coordinates and white balance parameters recorded in the EDID of the external display 120 are relatively inaccurate. In this case, the processor 114 may display a prompt message, for example, to remind the user to measure the external display 120 by connecting the color corrector to the electronic device 110, so as to obtain the above-mentioned information of the external display 120 more accurately. The first color coordinates and the first white balance parameters.

之後，處理器114可偵測是否有校色器連接至電子裝置110。反應於偵測到電子裝置110連接有校色器，處理器114可控制校色器量測外部顯示器120以取得外部顯示器120的上述第一色座標及第一白平衡參數。在一實施例中，校色器例如可藉由顯示一或多個特定的量測圖樣以量測外部顯示器120的R、G、B色座標及白平衡參數，但可不限於此。After that, the processor 114 can detect whether a color corrector is connected to the electronic device 110. In response to detecting that the electronic device 110 is connected to the color corrector, the processor 114 can control the color corrector to measure the external display 120 to obtain the first color coordinates and the first white balance parameters of the external display 120. In one embodiment, the color corrector may display one or more specific measurement patterns to measure the R, G, B color coordinates and white balance parameters of the external display 120, but it is not limited to this.

在另一實施例中，若未偵測到電子裝置110連接有校色器，處理器114可直接讀取外部顯示器120的EDID以取得外部顯示器120的上述第一色座標及第一白平衡參數（但可能較不準確）。In another embodiment, if it is not detected that the electronic device 110 is connected to the color corrector, the processor 114 can directly read the EDID of the external display 120 to obtain the first color coordinates and the first white balance parameters of the external display 120 (But it may be less accurate).

此外，在一實施例中，在讀取外部顯示器120的EDID之後，可相應取得外部顯示器120所支援的色域範圍（例如Adobe RGB、sRGB、DCI-P3等）。因此，處理器114亦可判斷外部顯示器120是否支援電子裝置110所支援的色域範圍中的任一者。在一實施例中，反應於判定外部顯示器120支援電子裝置110所支援的色域範圍中的一特定色域範圍（例如Adobe RGB），則處理器114可將外部顯示器120調整為對應於此特定色域範圍。In addition, in one embodiment, after reading the EDID of the external display 120, the color gamut range supported by the external display 120 (for example, Adobe RGB, sRGB, DCI-P3, etc.) can be obtained accordingly. Therefore, the processor 114 can also determine whether the external display 120 supports any of the color gamut ranges supported by the electronic device 110. In one embodiment, in response to determining that the external display 120 supports a specific color gamut range (such as Adobe RGB) in the color gamut range supported by the electronic device 110, the processor 114 may adjust the external display 120 to correspond to the specific color gamut range. Color gamut range.

此外，若外部顯示器120未支援電子裝置110所支援的色域範圍中的任一者，則處理器114可將電子裝置110調整為外部顯示器120支援的另一色域範圍。In addition, if the external display 120 does not support any of the color gamut ranges supported by the electronic device 110, the processor 114 may adjust the electronic device 110 to another color gamut range supported by the external display 120.

在一實施例中，若電子裝置110未支援上述另一色域範圍，則處理器114可維持電子裝置110及外部顯示器120個別的色域範圍，但本發明可不限於此。In one embodiment, if the electronic device 110 does not support the above-mentioned another color gamut range, the processor 114 can maintain the respective color gamut ranges of the electronic device 110 and the external display 120, but the invention is not limited to this.

此外，在另一實施例中，在執行步驟S210之前，處理器114還可先判斷外部顯示器120是否具有國際色彩聯盟色彩特性文件（ICC profile）。若是，則處理器114可予以忽略，藉以避免ICC色彩特性文件影響到後續的色彩調校操作。In addition, in another embodiment, before performing step S210, the processor 114 may also determine whether the external display 120 has an ICC profile. If so, the processor 114 can ignore it, so as to prevent the ICC color profile from affecting the subsequent color adjustment operations.

在依據以上教示取得外部顯示器120的上述第一色座標（以

Figure 02_image001
、
Figure 02_image003
、
Figure 02_image005
表示）及第一白平衡參數（以
Figure 02_image007
表示）之後，在步驟S220中，處理器114可取得電子裝置110的裝置顯示器的多個第二色座標（以
Figure 02_image009
、
Figure 02_image011
、
Figure 02_image013
表示）及第二白平衡參數（以
Figure 02_image015
表示）。在一實施例中，電子裝置110（例如，筆記型電腦）過去的相關校調的色彩參數將記錄於電子裝置110的相關軟體中（例如由電子裝置110的製造商所設計的軟體），故處理器114可直接從上述相關軟體取得得電子裝置110的裝置顯示器的上述第二色座標及第二白平衡參數，但可不限於此。After obtaining the above-mentioned first color coordinates of the external display 120 according to the above teaching (with
Figure 02_image001
,
Figure 02_image003
,
Figure 02_image005
Indicates) and the first white balance parameter (in
Figure 02_image007
After that, in step S220, the processor 114 may obtain a plurality of second color coordinates of the device display of the electronic device 110 (in order to
Figure 02_image009
,
Figure 02_image011
,
Figure 02_image013
Indicates) and the second white balance parameter (in
Figure 02_image015
Express). In one embodiment, the past related calibration color parameters of the electronic device 110 (for example, a notebook computer) will be recorded in the related software of the electronic device 110 (for example, the software designed by the manufacturer of the electronic device 110). The processor 114 may directly obtain the above-mentioned second color coordinates and the second white balance parameters of the device display of the electronic device 110 from the above-mentioned related software, but it is not limited to this.

在一實施例中，在取得第一白平衡參數及第二白平衡參數之後，處理器114還可判斷此二者之間的差異是否超過容忍值（例如±0.0015）。舉例而言，若第二白平衡參數為(0.312, 0.329)，則處理器114可判斷第一白平衡參數是否屬於(0.312±0.0015, 0.329±0.0015)，若否則可接續執行步驟S230及S240以續行調校。In one embodiment, after obtaining the first white balance parameter and the second white balance parameter, the processor 114 may also determine whether the difference between the two exceeds a tolerance value (for example, ±0.0015). For example, if the second white balance parameter is (0.312, 0.329), the processor 114 can determine whether the first white balance parameter belongs to (0.312±0.0015, 0.329±0.0015), if not, it can continue to perform steps S230 and S240. Continue to adjust.

相似地，在取得任一第一色座標及對應的第二色座標之後，處理器114還可判斷此二者之間的差異是否超過容忍值（例如±0.005）。舉例而言，若

Figure 02_image009
為(x, y)，則處理器114可判斷
Figure 02_image001
是否屬於(x±0.005, y±0.005)，若否則可接續執行步驟S230及S240以續行調校。Similarly, after obtaining any first color coordinate and the corresponding second color coordinate, the processor 114 can also determine whether the difference between the two exceeds a tolerance value (for example, ±0.005). For example, if
Figure 02_image009
Is (x, y), the processor 114 can determine
Figure 02_image001
Whether it belongs to (x±0.005, y±0.005), if not, steps S230 and S240 can be executed to continue the calibration.

之後，在步驟S230中，處理器114可產生用於將前述第一色座標及第一白平衡參數轉換為前述第二色座標及第二白平衡參數的轉換式。After that, in step S230, the processor 114 may generate a conversion formula for converting the first color coordinate and the first white balance parameter into the second color coordinate and the second white balance parameter.

之後，在步驟S240中，處理器114可基於轉換式調校外部顯示器120的顯示色彩。在一實施例中，處理器114例如可將轉換式中的轉換參數記錄於圖像處理單元（例如整合式圖像處理單元（iGPU）或獨立圖像處理單元（dGPU））中，並透過DP或HDMI等介面控制外部顯示器120，以調校外部顯示器120的顯示色彩。為便於理解上述概念，以下另輔以一具體實施例作說明。After that, in step S240, the processor 114 may adjust the display color of the external display 120 based on the conversion method. In one embodiment, the processor 114 may record the conversion parameters in the conversion formula in an image processing unit (for example, an integrated image processing unit (iGPU) or a stand-alone image processing unit (dGPU)), and pass it through the DP Or an interface such as HDMI controls the external display 120 to adjust the display color of the external display 120. In order to facilitate the understanding of the above-mentioned concepts, a specific embodiment is supplemented below for description.
