Description
本發明係關於一種檢測系統及其檢測方法，特別是一種能夠一次性自動檢測待測顯示卡各電性端子的影像功能是否正常的多影像訊號檢測系統及其檢測方法。 The invention relates to a detection system and a detection method thereof, in particular to a multi-image signal detection system capable of automatically detecting whether an image function of each electrical terminal of a display card to be tested is normal, and a detection method thereof.
隨著顯示技術及硬體科技的不斷進展，應用於電腦系統中的顯示功能不斷推陳出新。舉凡三維(3D)立體成像、擬真影像模擬，乃至於即時影像擷取和組合成像等功能都不斷被開發，且成為廣為消費者接受的標準規格。由於消費者針對電腦系統顯示功能的要求不斷提昇，顯示卡所支援的顯示介面也不再僅限於單純的靜態影像顯示。當前的顯示卡必須具備動態以及三維(3D)立體影像顯示的顯示介面，因此目前市售的顯示卡多半整合有視訊圖形陣列(Video Graphics Array,VGA)介面、數位視訊介面(Digital Visual Interface,DVI)以及高畫質晰度多媒體介面(High Definition Multimedia Interface,HDMI)等不同影像及聲音功能的多重顯示介面。 With the continuous development of display technology and hardware technology, the display functions used in computer systems continue to evolve. Features such as three-dimensional (3D) stereo imaging, immersive image simulation, and even instant image capture and combined imaging are constantly being developed and become standard specifications widely accepted by consumers. As consumers' demands for display functions of computer systems continue to increase, the display interface supported by display cards is no longer limited to simple still image display. The current display card must have a display interface for dynamic and three-dimensional (3D) stereoscopic image display. Therefore, currently commercially available display cards are mostly integrated with a Video Graphics Array (VGA) interface and a digital video interface (Digital Visual Interface, DVI). ) and multiple display interfaces for different image and sound functions such as High Definition Multimedia Interface (HDMI).
承前所述，為了確保顯示卡的品質，避免瑕疵品流入市場，顯示卡廠商通常在顯示卡出廠前皆會針對介面卡外觀、各連接端子及顯示卡的各種顯示介面進行品管及檢測。目前習用的檢測方式皆以人工的方式逐 一檢測顯示卡，檢測人員依序以檢測工具測試顯示卡的各個電性連接端子是否正常。檢測人員完成針對顯示卡之一電性連接端子的檢測程序後，必須重新啟動檢測系統，再經由檢測人員手動將顯示卡的另一電性連接端子電性連接於測試電腦上，方能針對顯示卡的另一電性連接端子進行檢測。由於前述重覆的電性插設作動，導致整體的檢測流程非常緩慢，同時也非常費工。 As mentioned above, in order to ensure the quality of the display card and prevent the product from entering the market, the display card manufacturer usually carries out quality control and detection on the appearance of the interface card, the connection terminals and the display interfaces of the display card before the display card leaves the factory. The current detection methods are all manually As soon as the display card is detected, the inspector sequentially tests whether the electrical connection terminals of the display card are normal by using the detection tool. After the tester completes the test procedure for one of the electrical connection terminals of the display card, the detection system must be restarted, and then another electrical connection terminal of the display card is manually connected to the test computer via the tester to display the display. Another electrical connection terminal of the card is detected. Due to the aforementioned repeated electrical insertion, the overall inspection process is very slow and laborious.
此外，在一般的顯示卡檢測流程中，檢測人員通常以肉眼檢視顯示卡不同顯示介面呈現畫面的相位、色階以及色彩飽和度是否符合標準。如果檢測人員發現顯示卡的電性連接端子不正常，或是不同顯示介面呈現畫面的相位、色階以及色彩飽和度不符合標準，則檢測人員判斷此顯示卡為瑕疵品，亦即顯示卡必須進行維修或是不得進行銷售。 In addition, in the general display card detection process, the inspector usually visually checks whether the phase, color gradation, and color saturation of the screen displayed by different display interfaces of the display card conform to the standard. If the inspector finds that the electrical connection terminal of the display card is abnormal, or the phase, color gradation and color saturation of the display interface of different display interfaces do not meet the standard, the tester judges that the display card is defective, that is, the display card must Repair or no sales.
然而，此等以人工方式逐項進行檢測的方式不僅曠日費時，且每張顯示卡必須測試的項目非常多，因此以人工方式顯然不具效率。此外，因為測試人員在測試過程中皆以肉眼進行判斷，進而因為誤判導致瑕疵品沒有被檢測出來，抑或是正常品被判斷為瑕疵品的機會也頗高，間接造成生產成本以及日後維修成本的增加。因此如何提昇顯示卡檢測流程的效率，並同時兼具檢測精確度，進而降低生產及日後維修成本，已成為製造廠商的重要課題。 However, such manual inspections are not only time-consuming, but also many items must be tested per display card, so it is obviously not efficient to manually. In addition, because the tester judged by the naked eye during the test, and the product was not detected because of misjudgment, or the chance that the normal product was judged to be defective, the production cost and the future maintenance cost were indirectly caused. increase. Therefore, how to improve the efficiency of the display card detection process, and at the same time have the detection accuracy, thereby reducing the production and future maintenance costs, has become an important issue for manufacturers.
鑒於以上的問題，本發明在於提供一種能夠一次性自動檢測待測顯示卡各電性端子的影像功能是否正常的多影像訊號檢測系統及其檢測方法，藉以解決習用的檢測方式皆必須仰賴人工逐一檢測顯示卡的各個電 性連接端子是否正常，導致整體的檢測流程非常曠日廢時的問題。 In view of the above problems, the present invention provides a multi-image signal detecting system capable of automatically detecting whether an image function of each electrical terminal of a display card to be tested is normal at one time, and a detecting method thereof, so that the conventional detecting method must rely on manual one by one. Detect the individual power of the display card Whether the sexual connection terminals are normal or not causes the overall inspection process to be very problematic.
此外，本發明亦解決習用的測試方法皆以肉眼進行判斷，導致誤判機率居高不下，間接造成生產成本以及日後維修成本的增加的缺陷。 In addition, the present invention also solves the drawbacks that the conventional test methods are judged by the naked eye, resulting in a high probability of false positives, indirectly causing an increase in production costs and future maintenance costs.

The image capture module 104 includes, but is not limited to, a digital camera, a camera, or a screen capture software tool built into the test host 102, which can be changed and adjusted by those skilled in the art. For example, if the image capturing module 104 is a digital camera, the display module 103 is aligned with the display module 103 during the detection process of the display card, and each test screen of the display module 103 is captured and converted into a plurality of test information. It is passed back to the test host 102. The test information described herein is a test screen for capturing the display module 103 through the image capturing module 104 for comparing and judging the display information of the test host 102 and the memory, and the detailed detection process is performed. The inventors are detailed in the subsequent paragraphs.
值得注意的是，在本發明所揭露的實施例中，顯示模組103以及影像擷取模組104的數目並不以一組為限，如欲提昇檢測效率，本實施例之檢測系統10可同時設置有多組顯示模組103以及影像擷取模組104，以同時呈現及擷取多組的測試資訊，因此測試主機102可選擇性針對待測顯示卡20之不同顯示介面進行逐項或同步的檢測。 It should be noted that, in the embodiment of the present disclosure, the number of the display module 103 and the image capturing module 104 is not limited to one set. To improve the detection efficiency, the detecting system 10 of the embodiment may be At the same time, a plurality of sets of display modules 103 and an image capturing module 104 are provided to simultaneously present and retrieve a plurality of sets of test information. Therefore, the test host 102 can selectively perform item-by-item or different display interfaces of the display card 20 to be tested. Synchronous detection.
如第3圖所示，當測試人員以第一實施例的多重檢測系統10實 施本實施例的檢測方法時，電性插設待測顯示卡20於電性插槽1011，令待測顯示卡20之各電性端子22、23、24分別電性連接於對應之連接埠1012、1013、1014(S101)；接著，以測試主機102之檢測軟體傳送檢測訊號至待測顯示卡20(S105)。 As shown in FIG. 3, when the tester uses the multiplex detection system 10 of the first embodiment When the detection method of the embodiment is applied, the display card 20 to be tested is electrically inserted into the electrical slot 1011, so that the electrical terminals 22, 23, and 24 of the display card 20 to be tested are electrically connected to the corresponding ports respectively. 1012, 1013, 1014 (S101); Next, the detection software of the test host 102 transmits a detection signal to the display card 20 to be tested (S105).
其次，依據檢測訊號依序測試待測顯示卡20之各電性端子22、23、24(S110)，並透過輸入切換器1015導引各電性端子22、23、24輸出不同的影像訊號(S115)，並傳送影像訊號至顯示模組103。 Then, the electrical terminals 22, 23, and 24 of the display card 20 to be tested are sequentially tested according to the detection signal (S110), and the electrical terminals 22, 23, and 24 are output through the input switch 1015 to output different video signals ( S115), and transmitting the image signal to the display module 103.
其次，顯示模組103根據影像訊號，對應呈現待測顯示卡20於各電性端子22、23、24的測試畫面(S120)。影像擷取模組104分別擷取顯示模組103之測試畫面，並轉換為複數個測試資訊回傳至測試主機102(S125)，換言之，測試主機102透過影像擷取模組104擷取待測顯示卡20各電性端子22、23、24輸出，呈現於顯示模組103之影像訊號。 Next, the display module 103 correspondingly presents a test screen of the display card 20 to be tested on each of the electrical terminals 22, 23, 24 according to the image signal (S120). The image capturing module 104 captures the test screen of the display module 103 and converts the plurality of test information back to the test host 102 (S125). In other words, the test host 102 retrieves the test image through the image capturing module 104. The electrical terminals 22, 23, and 24 of the display card 20 output the image signals displayed on the display module 103.
如前段所述，為增加檢測效率，本實施例所揭露的顯示模組103及影像擷取模組104的數目可依據待測顯示卡20的顯示介面數目對應增加或調整，以達到同時針對不同顯示介面進行檢測的目的，發明人不在此贅述。 As shown in the preceding paragraph, in order to increase the detection efficiency, the number of the display module 103 and the image capturing module 104 disclosed in the embodiment may be increased or adjusted according to the number of display interfaces of the display card 20 to be tested. The purpose of the display interface for detection is not described herein.
其後，如第4圖所示，測試主機120之檢測軟體依序比對各測試資訊與測試主機120儲存之複數個顯示資訊，例如測試主機102之檢測軟體依序比對各測試資訊與各顯示資訊中各圖像的座標值及三原色數值(S130)；透過判斷待測顯示卡20各電性端子22、23、24所呈現的顯示介面是否有色差或像素偏移等異常問題，從而判斷待測顯示卡之顯示介面是否正常。 Then, as shown in FIG. 4, the test software of the test host 120 sequentially compares the test information with the plurality of display information stored by the test host 120, for example, the test software of the test host 102 sequentially compares the test information with each Displaying the coordinate value and the three primary color values of each image in the information (S130); determining whether the display interface presented by each of the electrical terminals 22, 23, 24 of the display card 20 to be tested has an abnormality such as a color difference or a pixel offset, thereby judging Whether the display interface of the display card to be tested is normal.
若各該測試資訊各圖像的座標值及三原色數值與各該顯示資訊一致，則待測顯示卡20之各電性端子22、23、24為正常。舉例說明，測試資訊中紅色圓形A與顯示資訊中紅色圓形D的座標值與三原色數值皆相同，同時測試資訊中藍色方形B與顯示資訊中藍色方形E的座標值與三原色數值皆相同，且測試資訊中綠色周圍C與顯示資訊中綠色周圍F的三原色數值亦相同，則測試主機102判斷待測顯示卡20之顯示介面正常(S135)，測試主機102之檢測軟體經由測試介面於顯示模組103呈現待測顯示卡20之各電性端子22、23、24為正常(S140)。 If the coordinate value and the three primary color values of each image of the test information match the display information, the electrical terminals 22, 23, and 24 of the display card 20 to be tested are normal. For example, the coordinate value and the three primary color values of the red circle A in the test information and the red circle D in the display information are the same, and the coordinate value and the three primary color values of the blue square B in the test information and the blue square E in the display information are both The test host 102 determines that the display interface of the test card 20 to be tested is normal (S135), and the test software of the test host 102 passes the test interface. The display module 103 presents the electrical terminals 22, 23, 24 of the display card 20 to be tested as normal (S140).
相反地，若各測試資訊與各顯示資訊不一致，則判斷該待測顯示卡之顯示介面異常，例如測試資訊中紅色圓形A與顯示資訊中紅色圓形D的座標值與三原色數值不相同，或測試資訊中藍色方形B與顯示資訊中藍色方形E的座標值與三原色數值不相同，抑或是測試資訊中綠色周圍C與顯示資訊中綠色周圍F的三原色數值不相同，則判斷待測顯示卡20之顯示介面異常(S145)，則表示此顯示介面的電性端子可能故障，測試主機102之檢測軟體經由測試介面於顯示模組103呈現待測顯示卡20之對應的電性端子22、23或24其一者為故障(S150)，必須進行後續的維修再進行同樣的測試或直接判斷為瑕疵品。 Conversely, if the test information is inconsistent with each display information, it is determined that the display interface of the display card to be tested is abnormal. For example, the red circle A in the test information and the coordinate value of the red circle D in the display information are different from the values of the three primary colors. Or the blue square B in the test information and the coordinate value of the blue square E in the display information are different from the values of the three primary colors, or the green surrounding C in the test information and the three primary colors in the green surrounding F in the display information are not the same, then the judgment is to be tested. If the display interface of the display card 20 is abnormal (S145), it indicates that the electrical terminal of the display interface may be faulty, and the detection software of the test host 102 presents the corresponding electrical terminal 22 of the display card 20 to be tested via the test interface to the display module 103. One of 23, or 24 is a fault (S150), and subsequent repairs must be performed before the same test or directly judged as defective.
如此，本實施即可透過測試主機102比對各測試資訊及各顯示資訊中各圖像的座標值及三原色數值，自動判斷待測顯示卡20的各顯示介面是否有色差或像素偏移等異常問題，從而推斷各對應的電性端子22、23、24是否故障。測試主機120並透過顯示模組103呈現檢測結果，以供檢測人員紀錄，或由測試主機102自動紀錄於資料庫內，以利後續進行查核和 維修，以利後續調整和改善檢測流程。 In this way, the test host 102 can automatically determine whether each display interface of the display card 20 to be tested has an abnormality such as a color difference or a pixel offset by comparing the coordinate value of each image in the test information and each display information with the three primary color values. The problem is to infer whether the corresponding electrical terminals 22, 23, 24 are faulty. The test host 120 displays the test result through the display module 103 for the tester to record, or is automatically recorded by the test host 102 in the database for subsequent check and verification. Maintenance to facilitate subsequent adjustments and improve the inspection process.
請參照第1、2及5圖，第二實施例的檢測系統10及其檢測方法與第一實施例大致相類似，其差異在於，在本實施例中，測試主機102的檢測訊號係控制待測顯示卡20的各電性端子22、23、24輸出以線條為主的測試畫面，然測試畫面所呈現的顏色區塊或形狀可依據檢測需求，由本領域者自行調整及變更，且不以此為限。 Referring to Figures 1, 2 and 5, the detection system 10 of the second embodiment and the detection method thereof are substantially similar to the first embodiment, with the difference that in the present embodiment, the detection signal of the test host 102 is controlled. Each of the electrical terminals 22, 23, and 24 of the display card 20 outputs a test screen based on a line. However, the color block or shape presented by the test screen can be adjusted and changed by the user according to the detection requirement, and is not This is limited.
此外，本實施例的影像擷取模組104係連續擷取顯示模組103之測試畫面，並轉換為測試資訊回傳至測試主機102。本實施例的測試主機102係透過檢測軟體疊合上述的測試資訊，並比對測試資訊是否重疊，以判斷待測顯示卡20的各電性端子22、23、24呈現的測試畫面是否有抖動現象，藉以判斷待測顯示卡20的各電性端子22、23、24是否正常。 In addition, the image capturing module 104 of the present embodiment continuously captures the test screen of the display module 103 and converts the test information into test information and transmits it back to the test host 102. The test host 102 of the present embodiment detects whether the test picture presented by each of the electrical terminals 22, 23, and 24 of the display card 20 is jittered by detecting the test information overlapped by the test software and comparing the test information. The phenomenon is used to determine whether the electrical terminals 22, 23, 24 of the display card 20 to be tested are normal.
此處所述連續擷取顯示模組103之測試畫面係於1秒內連續擷取30張測試畫面的影像，並轉換為測試資訊回傳至測試主機102，且本實施例連續擷取畫面的時間及張數可依據需求對應變更，不以此為限。 The test screen of the continuous capture display module 103 continuously captures images of 30 test screens in one second, and converts the test information into test information and transmits them back to the test host 102, and the present embodiment continuously captures the images. The time and number of sheets can be changed according to the requirements, not limited to this.
因此，如第5圖所示，在本實施例的檢測方法中，步驟S220以顯示模組103根據影像訊號，對應呈現待測顯示卡20於各電性端子22、23、24的測試畫面係以線條為主，且步驟S225以影像擷取模組104連續擷取顯示模組103之測試畫面，並轉換為測試資訊回傳至測試主機102。 Therefore, as shown in FIG. 5, in the detecting method of the embodiment, the display module 103 displays the test image of the display card 20 to be tested on each of the electrical terminals 22, 23, 24 according to the image signal. The test image of the display module 103 is continuously captured by the image capturing module 104 in step S225, and converted into test information and transmitted back to the test host 102.
此外，本實施例測試主機102的檢測方法係透過檢測軟體疊合前述的測試資訊(S230)，測試主機102比對測試資訊及顯示資訊各畫面上的線條是否重疊(S235)，以判斷待測顯示卡20之各顯示介面是否正常。 In addition, in the detection method of the test host 102 of the embodiment, the test information is overlapped by the detection software (S230), and the test host 102 compares the test information and the lines on the screens of the display information (S235) to determine the test to be tested. Whether the display interfaces of the display card 20 are normal.
若各畫面上的線條如第6A圖所示完全重疊，表示顯示介面沒有 抖動的現象，因此測試主機102判斷待測顯示卡20之顯示介面正常(S240)，且測試主機102之檢測體經由測試介面於顯示模組103呈現待測顯示卡20之電性端子22、23、24為正常(S245)。 If the lines on each screen are completely overlapped as shown in Figure 6A, it means that the display interface is not The phenomenon of jitter, the test host 102 determines that the display interface of the display card 20 to be tested is normal (S240), and the test body of the test host 102 presents the electrical terminals 22, 23 of the display card 20 to be tested via the test interface to the display module 103. 24 is normal (S245).
相對地，若各畫面上的線條如第6B圖所示並未完全重疊，抑或是線條有加粗的現象，表示每張影像的線條略為不同且有抖動的現象，因此判斷待測顯示卡20之顯示介面異常(S250)，且測試主機102之檢測體經由測試介面於顯示模組103呈現待測顯示卡20之電性端子22、23、24為異常(S255)，必須進行後續的維修再進行同樣的測試或直接判斷為瑕疵品。 In contrast, if the lines on each screen are not completely overlapped as shown in FIG. 6B, or if the lines are bold, the lines of each image are slightly different and have a jitter phenomenon, so the display card to be tested is judged 20 The display interface is abnormal (S250), and the test body of the test host 102 presents the electrical terminals 22, 23, 24 of the display card 20 to be tested abnormally through the test interface 103 (S255), and must be subsequently repaired. Perform the same test or directly judge the product.
如此，本實施即可透過測試主機102比對連續擷取的各測試資訊及各顯示資訊中各圖像的線條是否重疊，自動判斷待測顯示卡20的各顯示介面是否有偏移或抖動現象等異常問題，從而如第一實施例推斷各對應的電性端子22、23、24是否故障，並透過顯示模組103呈現，以供檢測人員紀錄，或由測試主機102自動紀錄於資料庫內，以利後續進行查核和維修，以利後續調整和改善檢測流程。 In this way, the test host 102 can automatically determine whether each display interface of the display card 20 to be tested has an offset or jitter phenomenon by comparing the test information of the continuous capture and the lines of each image in each display information. In the first embodiment, it is inferred that the corresponding electrical terminals 22, 23, 24 are faulty, and are presented by the display module 103 for the detection personnel to record, or automatically recorded by the test host 102 in the database. In order to facilitate subsequent checks and maintenance, in order to facilitate subsequent adjustments and improve the inspection process.
請參照第1至6B圖，第三實施例的檢測系統10及其檢測方法結合第一實施例以測試主機102比對測試資訊及顯示資訊中各圖像的座標值及三原色數值，自動判斷待測顯示卡20的各顯示介面是否有色差或像素偏移等異常問題的檢測流程，以及第二實施例以測試主機102比對測試資訊及顯示資訊中線條是否完全重疊，抑或是線條有加粗的現象，自動判斷待測顯示卡20的各顯示介面是否有畫面偏移或抖動等異常問題的檢測流程，詳細步驟請參照第一實施例及第二實施例，不在此贅述，因此，本實施例的檢測方法相較於第一實施例及第二實施例顯更為精確及全面。 Referring to FIG. 1 to FIG. 6B, the detection system 10 of the third embodiment and the detection method thereof are combined with the first embodiment to test the host 102 to compare the coordinate values of the images in the test information and the display information with the values of the three primary colors, and automatically determine the Detecting whether each display interface of the display card 20 has a detection process of an abnormal problem such as a color difference or a pixel shift, and the second embodiment is to test whether the test host 102 compares the test information and whether the lines in the display information are completely overlapped, or whether the lines are bold. The phenomenon of detecting the abnormality of the screen offset or the jitter of each display interface of the display card 20 to be tested is automatically determined. For the detailed steps, please refer to the first embodiment and the second embodiment, and the details are not described herein. Therefore, the present embodiment is not described here. The detection method of the example is more accurate and comprehensive than the first embodiment and the second embodiment.
