Description

顯示系統及顏色特性測量方法Display system and color characteristic measurement method

本發明關於一種顯示系統及顏色特性測量方法，尤指一種可針對顯示單元之目前顏色得到RGB三通道之三校正輸出百分比之顯示系統及顏色特性測量方法。The present invention relates to a display system and color characteristic measurement method, in particular to a display system and color characteristic measurement method that can obtain three correction output percentages of RGB three channels for the current color of the display unit.

隨著對於解析度的要求愈來愈高，高階顯示器的應用也愈來愈廣泛。由於高階顯示器對於顏色特性之準確度的要求較高，使用一般測量設備所得到的顏色特性已無法滿足顏色校正的需求。為了提供準確的顏色特性給演算法使用，先前技術必須使用專業的測量設備（例如，具有分光鏡的光譜儀）來測量顯示器所顯示之顏色。然而，專業的測量設備的體積較大，且價格也較高，因此，較難被一般使用者接受。As the requirements for resolution become higher and higher, the application of high-end displays has become wider and wider. Because high-end displays have high requirements for the accuracy of color characteristics, the color characteristics obtained by using general measurement equipment can no longer meet the requirements of color correction. In order to provide accurate color characteristics for algorithm use, the prior art must use professional measuring equipment (for example, a spectrometer with a spectroscope) to measure the color displayed on the display. However, professional measurement equipment is relatively large in size and expensive, and therefore, it is difficult for general users to accept it.

本發明的目的之一在於提供一種可針對顯示單元之目前顏色得到RGB三通道之三校正輸出百分比之顯示系統及顏色特性測量方法，以解決上述問題。One of the objectives of the present invention is to provide a display system and a color characteristic measurement method that can obtain three correction output percentages of RGB three channels for the current color of the display unit, so as to solve the above problems.

根據一實施例，本發明之顯示系統包含一顯示單元、一儲存單元、一顏色測量單元以及一處理單元。儲存單元儲存RGB三通道之一第一相關參數以及RGB三通道之一第二相關參數。顏色測量單元測量顯示單元之一第一RGB三激值矩陣，且測量顯示單元之一目前顏色之三激值。處理單元根據目前顏色之三激值以及第一RGB三激值矩陣得到RGB三通道之三目前輸出百分比，且根據三目前輸出百分比、第一相關參數與第二相關參數得到RGB三通道之三校正輸出百分比。According to an embodiment, the display system of the present invention includes a display unit, a storage unit, a color measurement unit, and a processing unit. The storage unit stores a first related parameter of the three RGB channels and a second related parameter of the three RGB channels. The color measuring unit measures the first RGB tristimulus matrix of one of the display units, and measures the tristimulus value of the current color of one of the display units. The processing unit obtains the three current output percentages of the three RGB channels according to the three current color values and the first RGB three value matrix, and obtains the three corrections of the three RGB channels according to the three current output percentages, the first relevant parameter and the second relevant parameter Output percentage.

根據另一實施例，本發明之顏色特性測量方法包含下列步驟：提供RGB三通道之一第一相關參數以及RGB三通道之一第二相關參數；以一顏色測量單元測量一顯示單元之一第一RGB三激值矩陣，且測量顯示單元之一目前顏色之三激值；根據目前顏色之三激值以及第一RGB三激值矩陣得到RGB三通道之三目前輸出百分比；以及根據三目前輸出百分比、第一相關參數與第二相關參數得到RGB三通道之三校正輸出百分比。According to another embodiment, the color characteristic measurement method of the present invention includes the following steps: providing a first related parameter of one of the three RGB channels and a second related parameter of one of the three RGB channels; measuring a second related parameter of a display unit with a color measuring unit An RGB three-excited value matrix, and measuring the three-excited value of the current color of one of the display units; according to the three-excited value of the current color and the first RGB three-excited value matrix to obtain the current output percentage of the three RGB three channels; Percentage, the first related parameter and the second related parameter obtain the third correction output percentage of RGB three channels.

綜上所述，本發明係預先將RGB三通道之第一相關參數與第二相關參數儲存於儲存單元中。因此，使用者只要以顏色測量單元（例如，顏色感測器）測量顯示單元之目前顏色之三激值，處理單元即可根據RGB三通道之第一相關參數與第二相關參數得到RGB三通道之三校正輸出百分比。於一實施例中，RGB三通道之三校正輸出百分比可用以得到顯示單元之光譜。於另一實施例中，RGB三通道之三校正輸出百分比可用以得到CIE標準三激值座標。藉此，本發明不需使用專業的測量設備，即可提供準確的顏色特性（亦即，RGB三通道之三校正輸出百分比）給演算法使用。對於一般使用者而言，相當方便。In summary, in the present invention, the first relevant parameter and the second relevant parameter of the RGB three channels are stored in the storage unit in advance. Therefore, the user only needs to measure the tristimulus value of the current color of the display unit with a color measurement unit (for example, a color sensor), and the processing unit can obtain the RGB three channels according to the first and second related parameters of the RGB three channels The third correction output percentage. In one embodiment, three correction output percentages of the three RGB channels can be used to obtain the spectrum of the display unit. In another embodiment, the three corrected output percentages of the RGB three channels can be used to obtain the CIE standard tri-excitation coordinates. In this way, the present invention can provide accurate color characteristics (that is, the three-channel correction output percentage of three RGB channels) for use in the algorithm without using professional measuring equipment. For general users, it is quite convenient.
