Description of the invention () The present invention relates to an image display control system, especially an indicator device provided with a scene control device for scrolling (scroi), displayed in a window frame Vision control system. In today's computer world, window-based application operating interfaces have been widely accepted by computer users. When an application software uses a window program to display an image graphic in a window frame, if the image graphic is too large to fit in the window frame, only part of the image will be displayed in the window frame. In the window frame, the window program will generate a scrolling bar on the right or bottom of the window frame to scroll the image in the window frame. The part of the image displayed in the window frame is called a visual scene (vii e w), and the scroll is used to scroll the view of the image graphic so that different parts of the image graphic can be seen through the window frame. The Central Bureau of Standards, Ministry of Economic Affairs, ^ 工 Industrial and Consumption Hezhusha ^ (Please read the precautions on the back before filling in the wooden pages) U.S. Patent No. 5,530,455, invented by Gillick et al., Discloses a roller with a runner Mouse to scroll the view in the window frame. The vertical scrolling of the scene is controlled by the rotation of the wheel, and the horizontal scrolling of the scene is controlled by the wheel and a shift button to control the speed of the β scene scrolling and the amount and rotation of the scroll The speed of the wheel is proportional to the amount of rotation. There are many disadvantages to using this mouse wheel to control the scrolling of the scene. First of all, if you need to scroll the scene frequently, it may be easy to rotate the wheel frequently [fortunately, fatigue or soreness. Secondly, when the user needs two-dimensional scrolling of the scene, he must often change the friendliness of the mouse operation to change the direction of the scrolling of the scene, which is very wrong for the user. I heard that the paper size is subject to the Chinese National Standard (CNS) Λ4 specification (210XW7 male) dZ0799 A7 B7 V. Description of the invention (1) 4i 8th Ministry of Economic Affairs Central Standards Bureau Consumer Cooperation Du Yin ^ Up and down of the scene Scrolling is controlled by the forward and backward rotation of the wheel. The forward and backward rotation of the wheel causes the scene to scroll back and forth in a certain direction. It belongs to a specific interface control mode, and users usually need to try it a few times to become familiar with this specific control mode. When using this mouse, if the user must frequently change between up and down scrolling and left and right scrolling, the same forward and backward rotation will produce different visual scrolling actions. In this case, the user will It is necessary to frequently change and adapt to different control modes, which is difficult for users. Therefore, the main object of the present invention is to provide a vision control system capable of simultaneously performing two-dimensional vision scrolling. Another object of the present invention is to provide a scene control system capable of enlarging or reducing the scene of an image.

The motion control button 2 4 includes a plurality of sensing elements 6 6 disposed on the circuit board 6 2 of the mouse 10 to sense the direction of each finger input, and a touch pad 6 8 Set on the sensing element 6 6 for fingers Enter the introduction (read the notes on the back of the book first, and then fill out this page) The standard for binding pure paper is applicable to Chinese cabinet standards (CNS > Λ4 specifications (21ί) · χ 297 公 楚) 420799 A7 ___B7 _ V. Invention Explanation (VII). When accepting finger input, the touch pad 68 can be tilted in a certain direction according to the force of the finger within a fixed angle, so that the direction of the finger wheel can be changed by the touch pad 68. The sensed element 66 detects the signal and converts it into a scroll signal through the mouse 10. The Central Government Bureau of the Ministry of Economic Affairs, the Ministry of Economic Affairs and the Consumers ’Cooperation Right for Printing Disasters --------------------- Install (Please read the precautions on the back before filling this page) Sensing element 6 6 series It is made of conductive copper wires disposed on the circuit board 62 and is electrically connected to the control unit 28, which is arranged under the touch pad 68 in an approximately concentric circle manner. The touch pad 68 includes a convex surface 70 having elasticity and conductivity for contacting the sensing element 66. The sensing element 6 6 can be used to measure the pressure exerted by the finger 6 4 or the inclination angle of the touch pad 6 8 caused by the finger 6 4. The amount of pressure input by each finger 66 can be determined by measuring the number of sensing elements 66 contacted by the elastic convex surface, and then the control unit 28 of the mouse 10 will convert it into a scroll signal. The inclination angle generated by each finger input can also be determined by detecting the outermost one of the sensing elements 66 in contact with the touch pad 68, and converted into a scroll signal by the control unit 28 of the mouse 10. The force or tilt angle measured by the sensing element 66 can be used to control the scroll speed of the view 46 in the window frame 56. Fig. 5 shows the tilt of the elastic convex surface 70 of the touch pad 68 under the pressure of the finger 64, which causes the plurality of sensing elements 66 to be contacted by the touch pad 68. The greater the force exerted by the finger 64, the greater the number of sensing elements 66 contacted by the elastic convex surface 70. An outermost sensing element 72, which is touched by the touch pad 68, can be used to measure the tilt angle of the touch pad 68. The scrolling signal received by the driver 5G contains at least four parameters: △ X, A y, △ s, and F »The parameters (△ X, △ y) represent the two-dimensional E rule of the first finger rotation. Turns vector. The length of the vector is always equal to 丨, and the parameter △ X or A y This paper scale i4 uses the Chinese National Standard (CNS) Λ4 specification (21〇 × 297297) 420799 A7 ___ B7_____ 5. The description of the invention () is between +1 and -1. As is the zooming parameter, which represents that the front end 20 (zoom in) of the two-way button 18 is depressed by the user (Asil) or the rear end 22C is reduced by the user (As = -1). F represents the pressure input by a finger or the tilt angle it generates. If the visual control buttons 2 4 do not receive finger input, the parameters △ X, △ y and F will all be Q. And if either end of the two-way button 18 is not touched by a finger, Δ s will also be 0. Each scrolling signal is generated by the mouse 1G according to the finger input within a predetermined time interval (resolution). Therefore, the longer the keystroke time for one finger input, the more the number of scrolling signals generated by the mouse 10 The more, the window software 5 2 will scroll the view 4 6 in the window frame 5 6 according to each scroll signal received. This design eliminates the need for the fingers to continuously scroll in order to make the view 4 6 in the window frame 56, so it is very labor-saving. Please refer to Figures 6 to 8. When displaying the view of a larger image graphic, the 'window software 52 will automatically generate one or two scrolls for controlling the scrolling of the view within the window frame. If the vertical and horizontal dimensions of the displayed image are larger than the visual size displayed in the window frame, the window software 52 will set a vertical scroll and a horizontal scroll on the right and bottom of the window frame, as shown in Figure 6. The window frame 80 shown includes a vertical scroll 82 and a horizontal scroll 84. In this case, the window software 52 will scroll the scene according to each parameter of the scroll signal. In other words, if the parameters AX, △ y and F are not 0 ', the window software 52 will scroll at a speed proportional to F in the direction of (△ X. △ y), displayed in the window frame 80. Vision. Similarly, if the Li number As is not 0, the window software 52 will also enlarge I according to the parameter — —---I 1-I — ^ clothing II-— i I-Hi pin ^ (Please read the precautions on the back before (Fill in this page) This paper is in compliance with China ’s valve standards (CNS > Λ4 size (210X297)) A2099 99 Printed by the Employees ’Cooperative of the China Standards Bureau of the Ministry of Economic Affairs A7 B7 '____ 5.

In the case shown in Figure 7, 'Since only the vertical scroll 88 is displayed, the window software 52 does not need to scroll the view horizontally, even if the parameter △ y is not equal to 0. Here Windows Software 52 According to the parameter Δχ, the view is scrolled in the vertical direction and the parameter Δy is ignored. In the case shown in FIG. 8, because only the horizontal scroll 92 is displayed, the window software 52 will scroll the view in the horizontal direction according to the parameter Ay. The parameter Δχ is ignored in the scene. The parameter As can also be processed differently under different display conditions. When editing an image, the window software 5 2 can be limited to only the same speed in the vertical and horizontal directions. At the same time, the view of the image graphic is scaled so that the graphic content displayed therein will not be deformed β. When editing a text image, this limitation can be removed. This is because the vertical or horizontal proportion of the text image Changes usually do not affect the identification of individual texts a. Application software vendors should be able to decide which proportion of an application software should provide to users in different situations. It is more appropriate to use r as a window software 5 2 A preferred embodiment of the visual scrolling and zooming procedure performed. It shows how the window software 5 2 responds to the wink signal in different situations. The visual scene displayed by the window software 5 2 in this program is {Please read the precautions on the back before filling in this page] 8 ^^ The standard is applicable to the Chinese National Standard (CNS) Λ4 specification (210X297 public) 420T99 Printed by the Employees' Cooperatives of the Central Bureau of Standards, Ministry of Economic Affairs ¾ A7 B7 V. Description of the invention () Processed as a graphic image, so when executing the zoom function, the window software 5 2 will view the scene in the vertical and horizontal directions at the same proportion. Zoom in or out so that the graphic content is not deformed. Step (1) Receive a scroll signal from the driver 50; Step (2) Check if the two-way button 18 is depressed (ΛξιΟ); if not, go to step ( 4); Step (3) According to the As parameter, simultaneously enlarge or reduce the content of the scene in a predetermined ratio in the vertical and horizontal directions; Step (4) Check whether the scene control button 2 4 is depressed (△ X = △ y = F = 0); if not depressed, go to step (9); step (5) if only vertical scroll is displayed on the window frame, set △ dy = ϋ and calculate the moving distance of the view on the image graphics △ dx 'AcU and parameters Δχ and F Scale; go to step (8): Step (6) If the window frame only displays the horizontal scroll, set △ (jx = 〇, and calculate the moving distance Ady of the scene on the image graphics, △ dy is proportional to the parameters Ay and F Go to step (8); Step (7) If the vertical 殳 horizontal scroll is displayed on the window frame, calculate the moving distance Adx and Addy of the scene on the image, Adx is proportional to the parameters △ X and F, and △ dy It is proportional to the parameters △ y and F; Step (8) According to the moving distance △ dx, △ dy to obtain a new paper on the image graphics.
