92289TW IX. 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.

1252425 92289TW It is also in the monitor of the target. I I don't know what kind of graphics card δ is used for the PC, and the shank is evenly distributed. That is, in FIG. 6, for example, the PC 10 is provided with a video round out], such as σ 幵 / Α , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , In the case of two video output graphics cards B, the monitor 20 has two wheels A, and each channel has 192 〇 >< 24 〇〇 pixels, or is provided with a graphics card c In the case, the monitor (4) has two inputs 而' and each channel has 384Gxl2 (10) pixels. Moreover, in the case where there are four video output graphics cards D, the monitor 2G has four input ports, and each channel has 1920 x 1200 pixels. (Patent Document 1) Japanese Laid-Open Patent Publication No. 2000-206954 (page 丨 to 4, υ [Summary of the Invention] However, in the above-described conventional example, for example, even if the video input is η (η is an arbitrary positive number) input monitor, it is not often used 11 input for video input, but depending on the function of the connected PC, sometimes 11, sometimes η / two, In some cases, there is a case where the number of used items is changed, and there is a problem that the resolution to be described on the EDID cannot be surely determined. That is, when the video input of the PC is one input, it should be described in the edid The internal resolution 'is the original resolution of the monitor, and when the input is ^, it is necessary to record (the original resolution of the monitor) / η in the EDID. Thus, the resolution described in the EDID is correct. Although there is no 1252425

92289TW

However, 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.

Further, the EDm is merely an example of a name for describing a characteristic for displaying a video signal stored in the monitor 20, and other parameters may be used in the present invention. The CPU 11 is a female clothing having a private EDID control software for EDID which controls the monitor 20 of the present invention. As a feature of this embodiment, it is related to 13 1252425

92289TW PC 1 0 side related, only the addition of the EDID control software, and no hardware changes. That is, the PC, as shown in the functional configuration of the software of FIG. 2, includes an application 31, an operating system 32, a device driver 33, a graphic DD 34, and The video BIOS 35 and the EDID control software are installed on one of the application 31 and the device driver 33 in the CPU 11. Further, the function of the device driver 33 for installing the EDID control software is to take in information such as the EDID of the monitor 20. The CPU 11 performs EDID control via the USB line 60 or EDID control via the BIOS unit 15 and the DDC/CI line 50. Also, the CPU 11 reads the currently set EDID from the CPU in the monitor 20 via the USB line 60, the DDC/CI line 50, and the BIOS unit 15, and the CPU 11 is via the USB line 60 or the BIOS unit. 15 and DDC/CI line 50, and for the CPU in the monitor 20, the EDID change request is output. The EDID control software is used to check the video environment (video board) of the current system. In other words, in the EDID control software, the form of the video board used by the system, etc., is detected from a function or the like prepared by the operating system, and the number, frequency, and the like of the video signal that can be output by the board are determined. Moreover, in order to make such judgments, the characteristics of each of the video panels are described in advance in the EDID control software. Further, the user also has a path for outputting a menu to the screen for manual designation. The EDID control software is additionally inserted into the PC by, for example, the purchase of the soft (registered trademark) disk written by the program of the software or the communication of the program according to the program, without changing the existing application. Program, it will realize the video ring-14-

1252425 92289TW Checking the situation. Further, the EDID control software can be installed on the operating system 32 in addition to the application 3 1 and the device driver 3 shown in the embodiment, and can be based on the above-mentioned soft (registered trademark) disk or data communication. And install. As shown in FIG. 1, the monitor 20 includes a CPU 21 for performing DDC/CI communication while controlling the entire monitor; an EDID ROM 22 for storing EDID parameters and being connected to the DDC line for reading the EDID, a USB I/F 23 connected to the USB line 60; a video receiver 24 that receives a video signal from the n video signal cables 30; and a video signal received from the video receiving unit 24, displayed on the screen, and detected A logic unit 25 that outputs the frequency of the input video signal or the like. The CPU 21 is connected to the control software CPU 21 of the present invention for communicating with the PC 10 or for rewriting the EDID, and is now required to change the EDID input from the PC 10 via the USB line 60 or the DDC/CI line 50. The change of the EDID set in the EDID ROM 22. Further, in the present invention, other communication lines such as the USB line 60 and the DDC/CI line 50, such as RS232C (so-called serial communication line), may be used. Next, in the video display control system described above, the operation of changing the EDID will be described based on the flowcharts of Figs. 3 and 4 . 3 and 4 are flowcharts for performing an EDID changing operation in the CPU 11 on the PC 10 side. In addition, the EDID control software usually performs EDID calculation based on the highest performance of the system. Here, the so-called highest performance refers to -15-1252425

92289TW 1. 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

Whether the 92289TW is the same (110), when the output timings A and B are the same, the operation is terminated. 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). When Budan rewrites EDID to the appropriate one, it will be -17-

1252425 92289TW This setting is memorized, and the EDID is not required to change the video panel of the system. 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 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. In the figure, is the video cable 30 connected? (:1〇 and monitor 2〇 (step 2〇1), to start the system, after turning on the power of PC 10 and monitor 2 (step 2〇2), start the user for EDID control software. Interface application (so-called normal window (Windows (registered trademark), etc.)) (Step 2〇3). -19- 1252425

92289TW This program 'has the following functions' first performs the frequency display set in the current edid (step 204). Further, the resolution and frequency of the output can be displayed by the combination of the monitor 20 and the graphics card 12 of the PC 1 (step 2〇5), and can be selected from any of the displayed or the user does not use the icon. 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. As described above, in the present embodiment, on the PC side, the EDID control software calculates the EDID based on the resolution and frequency that the user has entered, and turns the eDID on the monitor side by rotating the view state. - Using the existing system, and according to the computer system that drives the monitor, the number of uses of the video input of the user is corresponding to the monitor, and good image processing can be performed thereby. ~ -20- 1252425

Further, in the present embodiment, the EDID changing operation of the first and second embodiments will be described separately. However, the present invention is not limited thereto, and the embodiments may be combined with the second and second embodiments. In this case, for example, it is conceivable that, when the system is started, all the operations shown in the flowchart of the first embodiment are automatically processed, and the normal operation is started in advance, and the user uses the system to perform the flow according to the second embodiment. The action shown in the figure is to change the frequency of the manual setting of the & condition or the automatic setting of the good frequency and the manually set frequency displayed on the surface to make a selection.
