在本發明被詳細描述之前，應當注意在以下的說明內容中，類似的元件是以相同的編號來表示。Before the present invention is described in detail, it should be noted that in the following description, similar elements are denoted by the same numerals.

參閱圖1與圖2，本發明自動化顯示效果檢測系統100的一實施例，適於檢測一顯示裝置900（例如電腦螢幕或電視），該顯示裝置900適於連續地顯示多個測試畫面90（例如Dolby Vision（杜比視界）之測試影片，共包含57個測試畫面），每一測試畫面90包含一測試色彩編號901（例如「Color patch 001」、「Color patch 002」…）及一測試色塊902，所述的自動化顯示效果檢測系統100包含一電腦裝置1、一色彩偵測裝置2及一影像拍攝裝置3。Referring to Fig. 1 and Fig. 2, an embodiment of the automatic display effect detection system 100 of the present invention is suitable for detecting a display device 900 (such as a computer screen or a TV), and the display device 900 is suitable for continuously displaying a plurality of test pictures 90 ( For example, the test video of Dolby Vision (Dolby Vision) contains a total of 57 test frames), each test frame 90 includes a test color number 901 (such as "Color patch 001", "Color patch 002"...) and a test color Block 902 , the automatic display effect detection system 100 includes a computer device 1 , a color detection device 2 and an image capture device 3 .

該電腦裝置1例如為一膝上型電腦或一桌上型電腦。The computer device 1 is, for example, a laptop computer or a desktop computer.

該色彩偵測裝置2電連接於該電腦裝置1，並用於偵測該測試色塊902以產生一色彩偵測資料。該色彩偵測裝置2例如為一色溫槍（例如Minolta系列色溫槍）。The color detection device 2 is electrically connected to the computer device 1 and used to detect the test color block 902 to generate a color detection data. The color detection device 2 is, for example, a color temperature gun (such as a Minolta series of color temperature guns).

該影像拍攝裝置3電連接於該電腦裝置1，並用於拍攝該測試色彩編號901以產生一色彩編號影像，並持續地將當前產生的該色彩編號影像傳送給該電腦裝置1。該影像拍攝裝置3為一網路攝影機（Webcam）。The image capture device 3 is electrically connected to the computer device 1 , and is used to capture the test color code 901 to generate a color code image, and continuously transmits the currently generated color code image to the computer device 1 . The image capture device 3 is a webcam.

參閱圖1及圖2，以下說明所述的自動化顯示效果檢測系統100執行的步驟。首先，如步驟S01所示，於該顯示裝置900開始連續地顯示該等測試畫面90時，該電腦裝置1對當前接收到的該色彩編號影像使用光學字元辨識技術（OCR）以獲得該測試色彩編號901，並由該色彩偵測裝置2獲取當前產生的該色彩偵測資料，並將該測試色彩編號901及該色彩偵測資料儲存成一筆測試資料。該色彩偵測資料在本實施例中，包含相關於色相圖的參數x、參數y、參數Lv之偵測數值。Referring to FIG. 1 and FIG. 2 , the steps performed by the automatic display effect detection system 100 will be described below. First, as shown in step S01, when the display device 900 starts to continuously display the test frames 90, the computer device 1 uses optical character recognition technology (OCR) on the currently received color code image to obtain the test The color number 901, and the color detection device 2 obtains the currently generated color detection data, and stores the test color number 901 and the color detection data as a piece of test data. In this embodiment, the color detection data includes detection values of parameter x, parameter y, and parameter Lv related to the hue diagram.

接著，如步驟S02所示，該電腦裝置1重複產生並儲存該測試資料直到該等測試畫面90顯示完畢。Next, as shown in step S02 , the computer device 1 repeatedly generates and stores the test data until the test screens 90 are displayed.

值得一提的是，若步驟S01的執行頻率（例如1秒1次）高於測試畫面90的切換頻率（例如5秒1次），會對於同一測試畫面90偵測超過一次而產生多筆對應於同一測試畫面90的測試資料，此外，由於執行光學字元辨識運算約需要1秒的計算時間，若在執行光學字元辨識運算的過程中顯示裝置900已切換至下一個測試畫面90，將導致接下來獲取的色彩偵測資料所對應的測試畫面90與先前執行光學字元辨識運算的色彩編號影像所對應測試畫面90並非同一個測試畫面90。為了解決前述問題，在本實施例中，當該等測試資料其中多筆測試資料的該測試色彩編號901相同時，該電腦裝置1自該測試色彩編號901相同的該等測試資料中選出該色彩偵測資料相同或相近者，再自該色彩偵測資料相同或相近的該等測試資料中選出其中一者作為一留存測試資料，並刪除該測試色彩編號901相同的該等測試資料中除該留存測試資料以外者。It is worth mentioning that if the execution frequency of step S01 (for example, once per second) is higher than the switching frequency of the test pattern 90 (for example, once every five seconds), multiple correspondences will be generated for the same test pattern 90 detected more than once. For the test data in the same test frame 90, in addition, since it takes about 1 second of calculation time to perform the OCR operation, if the display device 900 has switched to the next test frame 90 during the OCR operation, it will be As a result, the test pattern 90 corresponding to the color detection data acquired next is not the same test pattern 90 as the test pattern 90 corresponding to the color number image previously performed on the optical character recognition operation. In order to solve the aforementioned problem, in this embodiment, when the test color numbers 901 of the test data are the same among the test data, the computer device 1 selects the color from the test data with the same test color number 901 If the detection data is the same or similar, one of the test data with the same or similar color detection data is selected as a retained test data, and the test color number 901 is the same as the test data except the Those other than the test data are retained.

綜上所述，本發明自動化顯示效果檢測系統100藉由該電腦裝置1對當前接收到的該色彩編號影像使用光學字元辨識技術以獲得該測試色彩編號901，並由該色彩偵測裝置2獲取當前產生的該色彩偵測資料，並將該測試色彩編號901及該色彩偵測資料儲存成該測試資料，從而將測試程序進一步自動化，以改善先前技術可能發生人為失誤的情況，並降低人力成本，故確實能達成本發明的目的。To sum up, the automatic display effect detection system 100 of the present invention uses the optical character recognition technology to obtain the test color number 901 by the computer device 1 on the currently received color number image, and the color detection device 2 Obtain the currently generated color detection data, and store the test color number 901 and the color detection data as the test data, so as to further automate the test process, improve the human error that may occur in the previous technology, and reduce manpower cost, so the purpose of the present invention can really be achieved.
