I n c h :每寸之點數），9 0 0 萬像素之 QUXGAW (Quad Ultra Extended Gi. ap hies Array Wide(方形超寬圖形陣列）·· 3 8 4 0x24 00圖素（pixel)之高精細 且高像素數之圖像顯示裝置，其能極精細地顯示非常龐大之 資訊量之圖像資料，使用通常OA(辦公室自動化）用途和一 般PC導向之應用軟體（Application)之圖像顯示處理裝置與 此圖像顯示裝置相較，在顯示處理能力上會產生很大之落 ^ ’其情況係造成無法活用此圖像顯示裝置所謂之具有高精 細且高像素之特徵。 亦即，使用以往之光栅掃瞄（raster scan)方式之圖像顯 示裝置，在某時點上同時顯示之圖像之解析度（DPI)，由於 200415568 CRT之動作原理使然，在任一個領域上皆爲一樣，產生圖像 之P C側之視窗系統（w 1 n d 0 w S y s t e m )也以此圖像顯示裝置爲 前提執行圖像之產生。 在這種視窗系統上，描繪圖像資料之描繪單位係爲像素 (p i X e 1)，此像素之集合則代表桌上型電腦（d e s k Τ ο p )畫面之 顯示尺寸。此像素之圖像資料係記存於PC本體內之框記憶 體（由主記憶體和圖像轉接器VRAM所形成），被CRT C(CRT controller : CRT控制器）讀取後送到圖像顯示裝置。另外， 在P C上，應用軟體係將桌上型電腦畫面之一部份領域保留 作爲視窗並對此領域內之像素執行描繪。 此視窗系統邏輯上也能以比像素單位小之微細單位下 達描繪命令’但因將上述畫面之解析度作成在任何領域上皆 爲一定之關係’故在被寫入此框記憶體之階段上執行對應解 析度之擴大/縮小等之處理，藉此轉換成像素單位。因此之 故，比桌上型電腦畫面更高精細地描繪之圖像資料因縮小而 降低畫質，相反地，在描繪低精細之圖像資料之情形時，則 因擴大而使圖像資料變成過剩（redundancy)。 另外，具有液晶監視器之圖像顯示裝置能顯示之最大精 細度（pixel數）係固定的，若是桌上型電腦畫面之邏輯上之像 素數與圖像顯示裝置之物理上之像素數有不同之情形時，以 往有採用將桌上型電腦畫面之圖像資料擴大/縮小俾使其與 畫面之像素數一致之方法。特別是，擴大圖像之情形（桌上 型電腦畫面之像素數小於圖像顯示裝置之總像素數之情 形），因輸入P C之圖像資料無足夠之資訊，不管圖像顯示裝 200415568 置具有高解析度之顯示能力，無法有效地活用其能力。 另外，要求具高速運算處理能力和高速顯示處理能力之 局階（h i g h e n d )之3 D (三維）圖形處理系統，有使用多數之電 腦進行並聯處理，產生各個之描繪物件（object)，再使用專 用裝置將各個圖像予以再組成，藉此實現高速處理之方法 (L i g h t n i n g 2和M e t a b u f f e 1·等）。又，使用分類一第一方式 (Sort-first approach)方式等，事先將顯示畫面分割成區塊 狀，將此被分割之各個瓷磚之描繪分配給1個電腦執行顯示 處理，或使用分類-最終方式（Sort-last approach)方式等， 用多數之電腦描繪畫面內任意之描繪物件，最後將被描繪之 各個圖像予以合成處理並顯示。藉這些電腦再組成描繪之圖 像而得出之最終圖像係被記存在專用裝置之框緩衝器，然後 傳送到採通常之光栅掃描方式之圖像顯示裝置以進行顯示。 應用這種3 D圖形處理系統，雖能用各別之電腦作成低 解析度背景之圖像和高解析度描繪之物件，並將這些作成之 各個圖像予以合成，但是，這種組成，系統之規模變大，不 具泛用性，且需要昂貴之專用裝置，因此，現實上是不應用 這種系統。 另外，如專利文獻1所示，即使應用低階（l〇w_ end)專用 圖像顯示裝置，也能將多數不同解析度之圖像混合一起顯示 在圖像顯示裝置之畫面上。 (專利文獻1) 日本專利公報第200 1 -223 3 5號（第6〜9頁，第1圖〜 第5圖）。 -7- 200415568 (三）發明內容 (發明欲解決之課題） 不過，上述專利文獻1，具有須利用專用之應用軟體， 能選擇之解析度在應用軟體內部皆爲均一，爲了將各個解析 度之圖像合成爲1張，框記憶體之應用方法有限制，在P C 側也須對應通訊頻寬進行解析度轉換，因此無法保證依應用 軟體作成者之意圖進行描繪，導致產生畫質劣化等，及因自 圖像顯示裝置饋返（feed back)，致無法利用既存視訊介面 (Video interface)等之諸問題點。 _ 另外，上述之視窗系統，1個畫面具有各種性質之應用 軟體，依每個應用軟體最適畫面之解析度各異，沒有能滿足 全部之應用軟體之要求之最適畫面解析度之設定値。 例如，爲了期望執行圖像編輯那樣高精細顯示之應用軟 體而將圖像解析度作得高（亦即，將桌上型電腦畫面尺寸作 得大）時非對應於高解析度之其它應用軟體之視窗之顯示內 容和滑鼠游標，圖像（i c ο η)等之顯示則變成極小，從而具有 降低操作性和視認性之問題。 · 另外一方面，若降低畫面解析度（亦即，減小桌上型電 腦畫面尺寸）時即使在電腦上要描繪高精細之圖像，在圖像 資料被寫入電腦之框記憶體之階段上，全部之圖像資料皆要 配合此桌上型電腦畫面之解析度而被取樣，從而即使圖像顯 示裝置具有更高精細之顯示能力，也無法活用其能力，此爲 另一個問題點。 另外，以往許多之應用軟體基本上不是考量到D Ρ I而作 一 8 - 200415568 成的，例如，許多遊戲用之程序係以 V G A ( V i d e 0 G r a p h i c s Array: 640x460 pixel)爲前提而作成者’右將此程式在 Q ϋ X G A W之桌上型電腦畫面上執行時具有幾乎看不到任何 圖像之問題。因此，這種情形，產生須同時使用其它之應用 軟體進而須將畫面解析度變更設定於VGA之重要性。 另外，如微軟公司（Micro Soft Company)之視窗 (W i n d o w s )那樣，一部份之視窗系統，爲提商局精細顯示之 使用者親和性，具有能藉變更系統之設定，擴大顯示字體尺 寸和圖像（icon)尺寸之功能。但是，這種情形，將原本訊量 少之低解析度之圖像過多地擴大顯示，從而具有將有限資源 之框記憶體容量和通訊頻寬白白地浪費。 另外，視窗系統（window system)即便提供這樣之功肯t， 應用軟體若是獨自地決定字體大小和圖像大小之情形時則 完全會無效果。再者，此功能對應用軟體描繪之視窗顯示內 容也無效果。大多之應用軟體係藉將位元圖資料（bit map data)拷貝到框記憶體，以描繪顯示內容，但無考量高精細顯 示而作成之大多應用軟體，具有只顯示比應用軟體作成者想 要之尺寸小得極多之尺寸之問題。 本發明係鑑於上述問題點而創作出者，其目的係提供一

(2) The image data used for displaying images in the prior art is transmitted through the image driver of the image display processing device and the graphic adapter for image processing. To an image display device made of a CRT (panel). On the other hand, due to the advancement of LCD panel manufacturing technology, it has been developed and sold 'for example, more than 2000 DPI (Dotpe 1. I nch: dots per inch), 900 million pixels of QUAXGAW (Quad Ultra Extended Gi. Ap hies Array Wide (square ultra wide graphics array) ... 3 8 4 0x24 00 pixel (pixel) high-definition and high-pixel-count image display device, which can display very large information extremely finely Compared with this image display device, the image display processing device using ordinary OA (office automation) applications and general PC-oriented application software (Application) will produce a large drop in display processing capacity. ^ 'The situation is that it is impossible to make use of the so-called high-definition and high-pixel characteristics of this image display device. That is, the image display device using the conventional raster scan method can simultaneously display at a certain point in time. The resolution (DPI) of the image is caused by the operating principle of the 200415568 CRT, which is the same in any field. The window system (w 1 nd 0 w System) on the PC side that generates the image is also the same. The image is generated on the premise of a display device. On such a window system, the drawing unit for drawing image data is a pixel (pi X e 1), and the set of pixels represents a desktop computer (desk Τ ο p ) The display size of the screen. The image data of this pixel is stored in the frame memory (formed by the main memory and the image adapter VRAM) in the PC body, and is CRT C (CRT controller: CRT controller) After reading, it is sent to the image display device. In addition, on the PC, the application software system reserves a part of the area of the desktop computer screen as a window and performs drawing on pixels in this area. This window system can also logically The drawing command is issued in a fine unit smaller than the pixel unit, but the resolution of the above screen is made to have a certain relationship in any field. Therefore, the corresponding resolution is expanded at the stage of being written into the memory of this frame. It is converted into pixel units by processing such as reduction. Therefore, image data that is more finely drawn than a desktop computer screen is reduced to reduce the image quality. On the contrary, low-resolution images are drawn. In the case of data, the image data becomes redundant due to expansion. In addition, the maximum fineness (number of pixels) that an image display device with a liquid crystal monitor can display is fixed. If it is a desktop computer screen When the number of logical pixels is different from the number of physical pixels of the image display device, in the past, the image data of the desktop computer screen was enlarged / reduced to make it consistent with the number of pixels of the screen. method. In particular, in the case of an enlarged image (a case where the number of pixels on the desktop computer screen is smaller than the total number of pixels of the image display device), the image data input to the PC does not have sufficient information, regardless of whether the image display device 200415568 has High-resolution display capabilities cannot effectively utilize its capabilities. In addition, a high-end 3D (three-dimensional) graphics processing system with high-speed arithmetic processing capabilities and high-speed display processing capabilities is required to use most computers for parallel processing to generate individual drawing objects, and then use dedicated The device recomposes each image to achieve high-speed processing (Lightning 2 and Metabuffe 1 ·, etc.). In addition, using the Sort-first approach method, the display screen is divided into blocks in advance, and the drawing of each divided tile is assigned to a computer to perform display processing, or the classification-final Sort-last approach and other methods, using most computers to draw arbitrary drawing objects in the screen, and finally combining the processed images and displaying them. The final image obtained by recomposing the drawn images by these computers is stored in a frame buffer of a special device, and then transmitted to an image display device using a conventional raster scanning method for display. With this 3D graphics processing system, although separate computers can be used to create low-resolution background images and high-resolution depiction objects, and these created individual images can be synthesized, but with this composition, the system The scale becomes larger, it is not universal, and it requires expensive special equipment. Therefore, this system is not applied in reality. In addition, as shown in Patent Document 1, even if a low-level (10w_end) dedicated image display device is applied, it is possible to mix and display a plurality of images with different resolutions on the screen of the image display device. (Patent Document 1) Japanese Patent Publication No. 200 1 -223 3 No. 5 (pages 6 to 9, FIGS. 1 to 5). -7- 200415568 (3) Summary of the Invention (Problems to be Solved by the Invention) However, the above-mentioned Patent Document 1 has application software that must be used exclusively, and the resolutions that can be selected are uniform within the application software. The composition of the image is one. The application method of the frame memory is limited. On the PC side, the resolution conversion must be performed according to the communication bandwidth. Therefore, it is impossible to guarantee the rendering according to the intention of the creator of the application software. And due to the feed back from the image display device, it is impossible to use the existing video interface and other problems. _ In addition, in the above-mentioned window system, the application software of one screen with various properties varies with the optimal screen resolution of each application software. There is no setting of the optimal screen resolution that can meet the requirements of all application software. For example, in order to execute application software with high-definition display such as image editing, if the image resolution is high (that is, the desktop screen size is large), other application software that does not correspond to high resolution is used. The display content of the window and the mouse cursor, and the display of the image (ic ο η) become extremely small, which has the problem of reducing operability and visibility. · On the other hand, if you reduce the screen resolution (that is, reduce the screen size of a desktop computer), even if a high-definition image is to be drawn on the computer, the image data is written into the computer's frame memory. In the above, all the image data must be sampled in accordance with the resolution of the desktop computer screen, so that even if the image display device has higher-definition display capabilities, its capabilities cannot be utilized, which is another problem. In addition, in the past, many application softwares were basically created without taking into account PD I. For example, many games are created on the premise of VGA (Vide 0 G raphics Array: 640x460 pixel). 'Right when running this program on the desktop of Q ϋ XGAW, there is a problem that almost no image can be seen. Therefore, in this case, it is important to use other application software at the same time and set the screen resolution to VGA. In addition, like the Windows of Microsoft (Micro Soft Company), a part of the window system, for the user's affinity for fine display of the business bureau, has the ability to change the system settings to expand the display font size and Image size function. However, in this case, the originally low-resolution low-resolution image is enlarged and displayed too much, so that it has a waste of frame memory capacity and communication bandwidth of limited resources. In addition, even if the window system provides such a result, if the application software determines the font size and image size independently, it will be completely ineffective. Furthermore, this function has no effect on the display contents of the window drawn by the application software. Most application software systems copy the bit map data to the frame memory to describe the display content, but most application software created without considering high-definition display has only display than the application software creator wants The size is extremely small. The present invention was created in view of the above-mentioned problems, and an object thereof is to provide an image display processing method, an image display processing device, an image display device, and an image display processing system. In addition to utilizing high definition and high pixel count, In addition to the characteristics of the image display device, it can also maintain the integration with the existing PC architecture, thereby improving the user's operability and visibility.

This image display processing device 10 is a general PC including a processing device (not shown), a memory, and HDD. In addition, 'this image display device 10 is an application program SC operating system (PC) 12 and display driver 13 used by a PC, and a graphics adapter (graphicsadapt 〇r) 14 composed of hardware. The API (A pp 1 icati ο ro Program I nte l. Face: application interface) is composed of the above features and is composed of a hook driver 15 and a DDI (Device D Interface) hook driver. The image adapter 14 is composed of the features belonging to this embodiment, a memory 17, and a drawing engine and CRTC (not shown). Frame 17 is shown in the layout diagrams in Figure 2 and Figure 3. The image data area of the DPI (1920x1200 pixels) guaranteed by the window system (Windowssystem) management program of the image display device 10 ) 23a, 200 DPI data field (3 840 0x24 00 pixels) 23b, and digital image (alpha value) field 23c used to synthesize these two images, the second picture is the use of X 1 2 0 0 pixels The method of arranging the image data is to arrange the digital frame on the frame memory (Alpha Frame Scheme). Figure 3 is to arrange the image data in the line header area of the beginning part '/ i: (Line Header Scheme). It is necessary for this window management program to have an image of either 1 0 0 D P I or 2 0 D P I on the desktop screen. Therefore, as shown in Fig. 4, in this embodiment, the objects (windows) of 2 0 0 D P I are displayed in 24 places of 100 DPI (desktop computer screen) in 24 places. In addition, the image, the center 1 is a morphological memory with a soft river frame, 100 images, 1920, text, and other assignments; the state, the Central Bureau menu-20- 200415568 (menu), cursor, etc., such as , Write the image area of 100 DPI, and in the image display device 20, expand the vertical and horizontal dimensions twice by the expansion engine described later. λ On the other hand, like an image editing program, application software that wants to perform high-definition display, writes only the necessary areas into the image data area 2 3b of 2000 D ρ I. To display an image of that resolution in the area of the screen 24 of the image display device 20 or to perform a translucent composite display, etc., the information is written as the alphanumeric field in the alphanumeric field. 2 3 c. In addition, these writing operations are performed by the image editing program (or window management program) using a hardware drawing engine. In addition, the window system management program controls C R T C, C R T C as soon as the data in each field is updated. [J creates a video packet of the updated data and necessary information and sends it to the image display device 20. In order to realize the above-mentioned functions of the image display processing device like this embodiment, it is impractical to recreate the main body of the window system and the application software. Therefore, in this embodiment, like the Windows and X windows of Microsoft Corporation, the interface between the application software and the OS (API) and the interface between the OS and the display driver (DDI) are clearly defined. In addition, the driver that implements the API hook and the DDI hook is inserted, so that the above-mentioned window system management method can be realized without changing the existing application software and window system. Specifically, as shown in FIG. 1, the API hook driver 15 for implementing the API hook function and the DDI hook driver 16 for implementing the DDI hook function are inserted into the software layer, and the high-level API hook driver 15 is switched as needed. The domain to be mapped, the low-level DDI hook driver performs the majority of the mapping domain-2 1- 200415568 domain and CRTC control. FIG. 5 and FIG. 6 are flowcharts for explaining the processing operation of a PI hook driver} 5 and D D j hook driver 16. In Fig. 5, a PI hook driver 15 executes the analysis of the drawing API that belongs to the drawing command input from the application software n. The API hook driver judges whether the image material retrieved by using the API from this drawing is 100 DPI image data or 200 DPI image data (step 101). This image data is 100 DPI. In the case of image data, the acquired image data is 100 DPI, and the drawing API is notified to the display driver 13 via 0s 12 (step 102). In addition, if this image data is 2000 DPI image data, the acquired image is 2 0 DPI. The API for drawing is notified via 0 S 1 2 to the display driver 1 3 ( Step 10). In addition, the API hook driver 15 performs processing operations of taking in image data (including digital and digital data) and outputting it to the display driver 13 (step 104). In addition, during the analysis of the drawing API, the API hook driver 15 can also output to the application software 11 to suspend the execution of the information that can be used to modify the dream number, and can write the acquired image data. Notice of purpose. In FIG. 6, the display driver 13 takes in the drawing A PI and judges whether the image data of the drawing object indicates 100 DPI or 200 DPI (step 201). Here, if the drawing API is a notification indicating the intention of 100 DPI, the input image data is stored in a memory area of 100 DPI in a preset frame memory 17 (step 202). In addition, if the drawing API is a notification indicating the intention of 200 DPI, it is stored in the memory area of 200 DPI in the preset frame memory 17. In addition, the alphanumeric data can also be recorded in the memory area of the frame memory. -22- 200415568 In this way, in this embodiment, the image display processing device 10 can determine whether the image data is 100 D Pl or 2 0 D Pl after fetching the image data, and This image data and alphanumeric data are stored in the memory area (off-screen area) of each set of frame memory, so the frame memory can be effectively used. In addition, in this embodiment, digital text data that is not normally transmitted is processed as appearance image data and transmitted to the image display device together with the image data. Therefore, the data can be redundant, and the data can be enhanced. Debugging capabilities. In addition, in this embodiment, when the data in each field is updated, the CRTC control is used to perform differential transmission of the updated image data and control data, so the amount of data transmitted can be reduced. In addition, in this embodiment, although the drawing API is output to both 100 DPI and 200 DPI image data, the present invention is not limited to this. For example, only 200 API data is monitored and distributed to a desktop computer. The 100dpi image data on the screen is not a monitoring object, but can be directly stored in the frame memory. On the other hand, as shown in FIG. 1, the image display device 20 is composed of a high-definition and high-pixel number panel 21 of QUXGAW, and a monitor control unit 22, which is the one in this embodiment. With the characteristic composition, it receives image data of various resolutions from the image display processing device 10 via the monitor cable 3G. The monitor control unit 22 is, as shown in the composition diagram of FIG. 7, a frame memory 1 having two kinds of image data and digital data (control data) of 100 DPI and 200 DPI received and stored. 7 Frame memory 23 of the same composition, continued monitoring 3 30 Receive video packets, parse the packets, and execute image data and text-23- 200415568 Digital reception write module 24 receiving module (receiving module) 24 , Read out the image of 100 DPI from the frame memory 23 and execute the enlargement engine 27 which doubles the vertical and horizontal expansion; and read out the image of 200 DPI from the frame memory 23 and perform the synthesis engine combined with the aforementioned enlarged image 2 8 composition. With this composition, the monitor control unit 22 俟 receiving module 24 receives the image data of 1 00 DPI and 2 00 DPI, as well as alphanumeric data, and writes them into the frame memory 23 after analysis. Then, the image of 100 DPI is enlarged twice by the vertical and horizontal lines of 27 lines of the enlargement engine. In addition, according to the digital data of the received text, the synthesis engine 2 8 is used to synthesize two different resolution images on the panel 2 1 The synthesized image is displayed. In this way, in this embodiment, the image data of different resolutions of 100 DPI and 200 DPI are managed in a hierarchical manner. By combining the images of different resolutions, the images of different resolutions can be displayed on the same screen of the monitor. on. In addition, in this embodiment, although the API hook driver that realizes the API hook function is connected between the application software and OS, the present invention is not limited to this. For example, as shown in FIG. 8, as one of the functions of the application software 11 First, it can be composed so that the software 11 has an API hooking function 1 1 a, and then the API hooking function 1 a notification indicates a 200 DPI drawing API. In this case, the image data of 1 0 DPI and 2 0 DPI can be displayed on the same screen at the same time by the instruction from the application 11. Or you can switch to display only 100 DPI image data, or only display Image data of 200 DPI. In addition, in this embodiment, although the image display device first writes image data of each resolution into the frame memory, and then, upon reading, the image of 100 DPI and the image of 2 0 DPI are enlarged. Method for synthesizing image data (p0St-Read 200415568 and Blending: post-reading hybrid method), but the present invention is not limited to this. For example, as shown in the composition of FIG. 4 After receiving the 1 0 0 DPI image data and 2 0 DPI image data, the result is stored in the frame memory 2 3 of the disp 1 ayimage memory area 2 3 d method ( P e · W-Write B 1 ending In addition, in this embodiment, an identifier is added to each video packet transmitted, and image data and control data with different resolutions are mixed and transmitted to the image display device, but the present invention is not limited to this. For example, The image display processing device and the image display device can also mutually set the order of transmitting image data and control data of various resolutions stored in the frame memory. C RT C mixes these data according to this transmission order Transfer to image display device together. This transmission method is, for example, "there is a method to scan and record all fields stored in the frame memory by CRTC" to classify image data of various resolutions and control data from the image position in a video packet. This method is based on the preset transmission order. For example, "the first 1 920 points (dot) is the first line of the image data of 1000 DPI", and "the next 1 920 points is the alphanumeric character." "Line 丨", "The next 1 920 points is the second line of 100D PI image data", and these data are mixed together and transmitted to the image display device. In addition, this transmission method also has, for example, the use of CRTC to scan each memory area of image data of various resolutions stored in the frame memory and the memory field of control data to classify image data of various resolutions and control The way in which the data has been developed. In this way, for example, according to the preset transmission sequence, the memory area of 丨 〇〇D p 丨 of 192 × 20 pixels is scanned by CRTC first, and -25-200415568 is scanned next. The memory area of the text of 1 2 0 pixels is the final scan of the memory area of 3 8 4 0 X 2 0 0 pixels, and these data are mixed together and transmitted to the image display device. (Embodiment 2) One of the problems to date for a high-resolution image display device is the problem of local scaling during movie playback. In this case, when animations such as MPEG 1 and MPEG 2 are generated, the images are not transmitted to the image display device after being enlarged on the computer, but are executed on the image display device after the original animation data is transmitted. In the expansion method, it is not necessary to compress the logic of the communication bandwidth between the computer and the image display device. In particular, in the case of using an image display device exceeding 200 DPI which is more than fine, the image is usually enlarged at a relatively large enlargement ratio, so the effect is very large. However, it is difficult to implement due to the limitations of the existing video interface. Although the present invention limits the enlargement ratio to a certain value, it can easily solve the problem of enlargement after transmitting original animation data. The embodiment will be described below. This embodiment is different from that shown in FIG. 4 of Embodiment 1. The reference desktop computer screen is set to 200 DPI (3840x2400 pixels). In a certain area of the desktop computer screen, 1 0 0 The image data drawn by DPI is enlarged and displayed. However, combining this method and the differential transmission of the digital pv chain (Hnk) can greatly reduce the necessary communication bandwidth. Now consider the case where the original size of 320 x 240 pixels video CD is doubled vertically and horizontally on the screen of a desktop computer with 3840 x 2400 pixels, and it will be played back as a specific example. In this case, the animation playback program only needs to write the animation data into the image area of 1 0 DPI as it is, and whenever the animation image changes more than 200415568, the minimum 3 2 0 χ 2 4 0 The area of the pixels can be transmitted to the display device. On the other hand, if the desktop computer screen of 2000 dpi is used to transmit the entire screen to the image display device at one time, by using the differential transmission capability, as long as the screen is not updated, image data need not be transmitted. The animated image drawn on the image τιτ field of the 100 D PI image on the image display device is doubled vertically and horizontally, and then combined with the image of the desktop computer screen of 200 DPI After display. Another example assumes that the image display device can support two resolutions of 2000 D PI and 20 D PI. Here, when the animation data is enlarged by a factor of 10, the necessary communication bandwidth can be reduced by about 99%. · In this way, in this embodiment, 'use high-resolution images on desktop computer screens' is combined in a certain area within this desktop computer screen to expand the low-resolution images and display methods and digital The differential transmission of the p-V chain can expand the original animation data after transmission, thereby greatly reducing the necessary communication bandwidth. (Embodiment Mode 3) However, it is well known that most resolutions are mixed in the window system. The size and speed of the mouse cursor are changed according to the resolution of the coordinates where the cursor exists. For example, when the mouse cursor moves from the area of 100 DPI to the area of 20 DPI, the display size of the mouse cursor becomes smaller, the movement speed becomes slower, and the visibility becomes lower. In the present invention, in order to avoid such disadvantages, the window management system uses, for example, OS or application software to detect the display area where the mouse cursor exists, and executes the display control of the cursor, corresponding to the resolution of the detected display area, to expand or reduce. The size of the mouse cursor can also increase or slow down its movement speed, which makes the size and movement speed of the mouse cursor -27- 200415568 uniform. In other words, if the resolution of the coordinates of the cursor is high, the display control of the cursor is performed to make the size of the cursor larger and the speed of movement is faster. On the contrary, if the resolution of the coordinates of the cursor is low The cursor display control does not make the cursor size smaller and slows down the movement speed. In this way, in this embodiment, the display control is performed. The resolution of the coordinates corresponding to the existence of the mouse cursor changes the size and moving speed of the cursor, so it can be independent of the resolution of the coordinates of the existing mouse cursor. The moving speed and size are uniformly displayed on the appearance, which can improve the operability and visibility of the user. (Embodiment 4) Although the above-mentioned embodiment describes a method of sending an image of each resolution to an image display device, and performing enlargement or reduction processing in the image display device, and synthesizing them, the present invention It is not limited to this, and it is also possible to realize a method of performing an enlargement, reduction, and composition process using an image display processing device such as a PC, and transmitting the synthesized image to an image display device such as a monitor. This embodiment will be described below using a schematic composition of the image display processing apparatus of FIG. 10. The image display processing device according to this embodiment is provided with the above-mentioned frame memory} 7 in a graphics adaptor 1 4 and depicts an engine i 8 and an unillustrated CRTC. This embodiment mode is similar to the above-mentioned embodiment mode, and will describe a case where an image of 2000 D PI is displayed on the desktop screen at 100 DPI (1920x1200 pixels). In this embodiment, the image display processing is completed by the following procedure. 200415568 1. Logical desktop computer screen size is set to 1 920x 1 200 pixels, but the frame memory 17 is set to be able to memorize the image area of 3 84 0x2400 pixels. 2. When the application software A wants to draw an image at 100 DPI, the drawing engine 1 8 of the image converter 14 is used to expand the entire image both vertically and horizontally by two and write it to the frame memory 17. When the application software B wants to draw an image in 2000 D PI, it writes it to the frame memory 17 as it is. 3. The image data of 2000 DP 1 (3 8 40 x 24 00 pixels) created on the frame memory 17 of the image display processing device 10 is transmitted to the image display device as it is. 4 · If the command to read back the image data drawn with 100 DPI from the frame memory is issued (1) Reduce the size of the frame memory expanded to 200 DPI and return the data. (2) When drawing an image, save the 100 DPI image that has not been additionally expanded in an off-screen area and return the data. The feature of this embodiment is that the transmission method of video data from the image display processing device 10 to the image display device 20 is not special and has the property of being interchangeable with the existing method, and it is not necessary in the image display device. Complex functions are constructed, so it is easier to realize the image display processing of the present invention. (Embodiment 5) In addition, "the above embodiment" is connected by one image adapter! Article Se Vision Power Continued 3 0 'Mix multiple resolution image data and control data to the image display device, but the present invention is not limited to this. For example, a map with a large number of outputs can be used. Multiple adapter systems such as adapters, or multiple 29-29200415568 couplers connected to a PC, connect multiple cables to transfer images to the image display device. Figure 11 shows that there are three image adapters i 4 a to 1 4 c installed on one PC and frame memory 1 7 a within each adapter 14 a to 1 4 C. ~ 1 7 c respectively write the image data of 2000 DPI, the image data of 100 d PI, and the digital digital data indicating the synthesis method, with 3 matching devices 1 4 a ~ 1 4 c and It is connected to one image display device 20 via three cables 3 a to 3 0 c, and then the image display device 20 synthesizes the image of each resolution. The image data of 200 DPI is only stored in the frame memory i7a, and the image data of 100 DPI Lu is only stored in the frame memory 17b. In addition, the alphanumeric data is only stored in the frame memory 17c. These data are input to the image display device 20 via respective dedicated cables 30a to 30c, and are synthesized by the synthesis engine in the image display device 20 and displayed on the panel 21. In this way, in this embodiment, the image and digital data of various resolutions are transmitted to the main image display device by separate electric insulation according to various data. Therefore, it is not necessary to add the type and resolution of the data to the video packet. Information. Therefore, this embodiment is easier to construct on the image display processing device (PC) side. The present invention is not limited to the above-mentioned embodiments, and various changes can be made without departing from the scope of the invention. (Effects of the Invention) As described above, since the present invention displays a large number of images with different resolutions on the same screen of the image display device, it can maintain the features of the high-resolution and high-pixel image display device, and maintain Integration with the existing PC architecture can improve user operability and visibility. -30- 200415568 In addition, the present invention enables images of various resolutions to be executed simultaneously or switched in the same screen, thereby improving user operability and visibility.
