Description of the Invention: [Technical Field] The present invention relates to an EDID (Extended Display Identification Data: Parameter Information) for displaying an image signal of at least one system and The image display control method, the image display device, the image processing device, and the image display control system are modified. [Prior Art] In recent years, the display for use in a computer system has a super-fine display screen, and has been significantly developed with the advancement of liquid crystal panel manufacturing technology, for example, a GUXGAW (Quad Ultra Extended Graphics Array Wide: 3840x2400) A video display device (hereinafter referred to as a "monitor") of a high-definition liquid crystal monitor having a high pixel count such as a pixel or a QUXGA (Quad Ultra extended Graphics Array: 3200x2 400 pixels) has been developed and sold. It can display image data of a very large amount of information in high definition. This kind of ultra-high-definition display requires a plurality of video signal lines because it needs to transfer a large amount of data from a computer. In this case, a personal computer (hereinafter referred to as "PC") as an image processing device needs to detect the type of the monitor having a plurality of input ports. Therefore, the PC reads the EDID from the monitor via the video cable and the communication protocol of the so-called DDC (Display Data Channel). Then, the PC obtains information such as the size, the resolution, the corresponding frequency, and the like of the driven monitor based on the read EDID, and outputs image signals such as video signals in an optimum display manner.

問題,但是在該解像度被錯誤記載的情況,或是在初期值 並未以對應PC之視頻輸出條數的解像度來記载的情況,就 會發生顯示於監視态上之影像的大小為正確,但顯示與實 際之大小不合。亦即,此係因驅動監視器之信號依存於PC 之視頻輸出條數之故,在現狀中,監視器會有無法辨識要 在PC侧輸出何種信號較好的問題。 因此,可考慮例如在專利文獻i中所記載者,即變更輸出 影像信號之PC侧的系統(例如圖形卡或其裝置驅動程式等) 本身,忽視監視器之參數(例如不讀取),而輸出已決定的信 號。然而,該系統之變更,係在特定之監視器用途中依用 戶要求來製作圖形卡,此會使系統之通用性降低。更且, 按照監視器側之例如解像度等,變更安裝於pc侧之圖形 卡’由於實際問題多有監視器與系統(PC)之製造商不同的 情,,所以製造困II,同時即使可製造亦會有在開發上花 費時間,且製造成本變高的問題點。 2發明係有ϋ於上述問題點而開發完成者,#目的在於 a 一《種▼ *利用既有之系統,而-面按照驅動監視器 之電月“、统’使任意之視頻輸入的使用數與監視器對應, 且f此進行良好之影像處理的影像顯示控制方法、影像顯 不裝置、影像處理裝置及影像顯示控制系統。 i纟明之其他目的,係在於提供-種藉由可輕易進 味用之參數的變更’而可最適當地設^可對應之影像 Ί用之頻率、視頻輸出條數等的影像顯示控制方 “象頒不裝置、影像處理裝置及影像顯示控制系統。 1252425However, in the case where the resolution is erroneously recorded, or when the initial value is not described in the resolution of the number of video outputs corresponding to the PC, the size of the image displayed on the monitor state is correct. But the display does not match the actual size. That is, since the signal of the drive monitor depends on the number of video outputs of the PC, in the current situation, the monitor may have a problem that it is impossible to recognize which signal is to be output on the PC side. Therefore, for example, it is conceivable that the system described in Patent Document i changes the system on the PC side (for example, a graphics card or a device driver thereof) that outputs an image signal, and ignores the parameters of the monitor (for example, does not read). Output the determined signal. However, changes to the system result in the graphics card being created by the user in a particular monitor application, which reduces the versatility of the system. Furthermore, according to the resolution on the monitor side, for example, the graphics card installed on the pc side is different from the manufacturer of the system (PC) because of actual problems, so that the manufacturing is difficult, and even if it can be manufactured There will also be problems in that development takes time and manufacturing costs become high. 2 The invention is developed in accordance with the above problems, and the purpose of # is to use a system to use the existing system, and to use the video input of the monitor. The number corresponds to the monitor, and the image display control method, the image display device, the image processing device, and the image display control system perform good image processing.

Use all available video signal cables (due to the update rate). 2. Use the highest update rate (ie, the transmission rate of the image information can be sent several times, the faster the screen will move smoothly). In FIG. 3, the video signal cable 3 is first connected to the PC 1 and the monitor 2 (step 101), and the system is started to turn on the power of the PC 1 and the monitor 20 (step 102). . As the system is started, the CPU that installs the edid control software uses the function of the operating system standard preparation to investigate the type of the video board or the name of the manufacturer. Then, in the original video card, the number of video signal cables that can be used is determined (step 103), and the characteristics of the video board and the characteristics of the monitor 2 that are held in each cpuu are calculated. The highest performance output timing, etc. (step 104). In addition, this output timing is treated as a. Next, the output of the EDm is made to the monitor 2 via the USB or DDC/CI line (step 1〇5), and it is judged whether or not there is a response of outputting EmD from the monitor 2 (step 1 〇 6). Here, when there is a response of the EDm from the monitor 20 via the USB or 〇1^/〇1 line, the current EDm in the monitor 2〇 is read (step 1〇7), and it is judged that it can be used from jED1D. The number of the video signals is wound (step 108), and then the most appropriate output timing and the like described in the EDID (step (10)). In addition, this output timing is treated as B. Secondly, 'in Figure 4', it is judged whether the calculated output timing is the same, :: the output video timing is the premise of the number of video coils (step 1〇3 'the number) and the read output timing (4) Number of items (number of steps (10)) • 16 - 1252425

In the different case, the CPU 11 outputs the change request including the EDID of the sequence A via the USB or DDC/CI line. Go to the monitor 20 (step 111). Then, it is judged from the monitor 20 whether or not there is a response of the EDID (step 112). In addition, in step 11 ,, the number of cables actually used is different from the number of cables that can use the main body due to the user's intention, failure, etc., although there may be a number of cables of A and B. Different situations will be explained at the end of the paragraph. Here, when there is a response of the EDID from the monitor 20 via the USB or DDC/CI line, the EDID is read (step 113), and the EDID is overwritten to determine whether it is updated to a new value (step U4) . Here, when it is confirmed that the EDID has been rewritten, the system is restarted as needed. This is due to the fact that when the system is not restarted depending on the operating system, there is no possibility of correctly re-entering the EDID. Then, returning to step 108 of Fig. 3, the number of available video signal cables is judged from the EDID, and the most appropriate output timing B is read, and it is judged again whether the output timings 8 and 6 are the same. Moreover, in step 114, if the EDID is not updated to a new value, that is, if there is no appropriate EDID in the setting of the EDID that is stored in the monitoring state 20, it is determined whether the system has a suitable monitor. The setting of 2〇1〇 is used as the data, or whether the calculation can be used to calculate EmD (step 115). Here, in the case where the system has an EDIC setting suitable for the monitor 2 as the data 'or the calculation can be used to calculate the EDID, the data of the edid is dumped to the monitor 20, and the EDID is written (step 117).

Therefore, the CPU changes the EDID according to the EDID control software, and only the system configuration is changed. As described above, in the present embodiment, the PC side and the hardware are not changed. When the EDID control software is added, the monitor side is notified of the change of the EDID or the addition of the CPU or the control software, and the EDID is changed. Therefore, while using the existing system, the number of use of any video input can be matched with the monitor according to the computer system that drives the monitor, and good image processing can be performed thereby. Further, in the present embodiment, since the EDID control software is used between the PC and the monitor to change the EDID request and the response, the corresponding image signal can be optimally set by simply changing the parameters for display. Frequency for transmission, number of video output, etc. Secondly, although it is possible to use, for example, the original m video signals, only n (n < video signal cables) can be used due to factors such as the user's intention or failure, and then this case will be explained. In this case, in the step In the case, for example, the video signal cable is only connected to the channel 0 that is used. Then, when the system is started, the number (m) of video signal cables that can be used is judged to calculate the most appropriate output timing A (steps 1〇2 to 1〇4). Next, the current EDID in the monitor 20 is generated (steps 1〇5 to 107). In this case, since the EDID can be read from all connected USB lines or individual DDC/CI lines, EDID can be read from n of the strips. Next, the output timing recorded in the EDID is read (steps 108 to 109).
1252425 92289TW 在此,由於可明白實際連接之電纜的條數11、與原本假設 之電繞的條數m不同,所以監視器2〇,會以n條為前提而重 新計算時序A。在此,重新計算的輸出時序a,由於與輸出 4'序B不同,所以會將如包含時序八之EDID的變更要求輸出 至監視器20,並讀入經變更過之新的EDID而判斷輸出時序 A與B之一致,以進行步驟11〇〜117之動作。 如此,在本實施形態中,根據所讀入之EDID而計算的輸 出時序,即使非為本來之最佳輸出時序的情況,由於亦會 對監視器侧進行EDID之變更通知,並變更EDID,所以可一 面利用既有之系統,而一面按照驅動監視器之電腦系統, 使任意之視頻輸入的使用數與監視器對應,藉此進行良好 的影像處理。 (實施形態二) 在此,例如被提供的電影之動晝,係24Hz,當播放時不 以與其影像源相同之頻率(24 Hz或其整數倍)驅動時,就會 發生跳框等的現象。該情況,例如即使其係最佳輸出時序 為30 Hz之圖形卡,仍會以設定輸出時序為24 Hz2畫質較 佳。 ' 因此,在本實Μ形悲二中,係根據圖5之流程圖來說明使 用者進行任意變更頻率等之人工設定的情況。圖中,以視 頻^號電纜30來連接?(:1〇與監視器2〇(步驟2〇1),藉以啟動 系統,在使PC 10及監視器2〇之電源接通之後(步驟2〇2),開 始著手EDID控制軟體用之使用者介面應用程式(所謂普通 之視窗(windows(註冊商標)等的程式))(步驟2〇3)。 -19- 12524251252425 92289TW Here, since it can be understood that the number of cables 11 actually connected is different from the number m of electric windings originally assumed, the monitor 2 重 recalculates the timing A on the premise of n. Here, the recalculated output timing a is different from the output 4' sequence B, so the change request including the EDID including the sequence 8 is output to the monitor 20, and the changed new EDID is read and the output is judged. The timings A and B are identical to perform the operations of steps 11 〇 117. As described above, in the present embodiment, even if the output timing calculated based on the read EDID is not the original optimal output timing, the monitor side is notified of the change of the EDID and the EDID is changed. It is possible to perform good image processing by using the existing system and by using the computer system that drives the monitor to match the number of arbitrary video inputs to the monitor. (Embodiment 2) Here, for example, the motion of the provided movie is 24 Hz, and when it is played without being driven at the same frequency (24 Hz or an integral multiple thereof) as its image source, a jump frame or the like occurs. . In this case, for example, even if it is a graphics card with an optimal output timing of 30 Hz, the picture quality is better at a set output timing of 24 Hz2. Therefore, in the case of the second embodiment, the manual setting of the arbitrarily changing frequency or the like is described based on the flowchart of Fig. 5.

The input mechanism (mouse or keyboard, etc.) is selected (step 206). In addition, the resolution and frequency supported by the graphics card are differentiated by the function of the operating system standard without any special processing. Here, when the user selects the resolution and the frequency, the CPU 11 calculates the EDID using the EDID control software according to the selected resolution and frequency (step 207), and outputs the calculated EDID to the monitor 2〇. And the EDID set in the monitor 20 is changed (step 208). In addition, when the EDID of the confirmation monitor 20 is rewritten, the system is restarted as needed. Further, the setting of the desired frequency can be set in advance, for example, in addition to the initial setting of pci〇i (when the graphic card 12 is installed and the name is registered, etc.). In this case, the 〇SD (〇n Screen Display) for setting the brightness of the screen of the aging person or the frequency of the input signal can also allow the user to select the desired frequency.
