Abstract

PURPOSE:To determine freely corresponding relation between the movement of a hand and the movement of a marker, to make easy an input operation and to extend a menu area by setting optionally corresponding relation between an input area on a coordinate inputting device and a displaying area on a display screen. CONSTITUTION:When the coordinates of a point P1 in an area R1 are inputted from the coordinate inputting device, the coordinate position inputted from the corresponding relation with areas R1 and r1 is converted to a coordinate value P1, the marker is displayed at the position and the pattern processing instruction is executed. In the same way, when a point P2 in an area R2 is inputted, the coordinate position of the point P1 is converted to the point P2 of a display screen 12, the marker display is executed and the pattern processing instruction of the area R2 is executed. Consequently, when the coordinate information with high accuracy is to be inputted, for the area on the display screen, the coordinate input area is corresponded wider, many areas are to be established, and then, the area is made small up to the size of the extent in which the visible characteristic is not damaged.

Description

Detailed Description of the Invention (Industrial Application Field) The present invention relates to input processing of various commands in a graphic processing device, and particularly to graphic processing using a coordinate input device such as a tablet and a display device such as a CRT display. The present invention relates to a coordinate input method and apparatus used when inputting various graphic processing commands in an apparatus.

(Prior art and its problems) In a graphic processing device that combines a coordinate input device such as a tablet, digitizer, or mouse with a CRT display as a display device, hand movements on the coordinate input device using a stylus pen or cursor, for example, From the coordinate point data obtained according to the coordinate data and the relative coordinate data obtained by the movement of the mouse on the desk, various figures can be input according to the coordinate values, and the command menu assigned to the area on the coordinate input device can be input. I would make a selection and execute the selected content. In conventional coordinate input means and devices of this kind, the correspondence between the input area on the coordinate input device and the position of the display area on the display screen, the movement of the hand on the coordinate input area and the movement of the marker on the display screen are determined. The relationship between the two was fixed. In other words, the entire coordinate input area corresponds to a certain area on the display screen, and all points in the coordinate input area are input with the same accuracy, and a marker is displayed on the display screen corresponding to the input coordinate position. By doing this, the position on the coordinate input area was confirmed.

In such conventional coordinate input methods and devices that implement this method, the correspondence between the positional relationships of areas is fixed, and the operation range on the coordinate input area and the movement range of the marker on the display screen are always constant. Because of the correspondence relationship, it was difficult to satisfy both operability and visibility of the display at the same time.

Furthermore, since the movement of the man's hand and the movement of the marker correspond in a fixed manner, the figure input area and the menu area, which use the input coordinate point data as is, can be input with the same accuracy on the input area of the coordinate input device. If the graphic input area that requires fine precision is widened, the menu area that does not require much precision will become narrower, making it impossible to select more menu items, or conversely, increasing the number of menu items. As a result, if the accuracy in the coordinate input area is lowered, the disadvantage is that the necessary accuracy cannot be obtained in the graphic input area.

(Object of the invention) The present invention has been made in consideration of these circumstances,
The purpose of this invention is to arbitrarily set the correspondence between the input area on the coordinate input device and the display area on the display screen, so that the movement of the hand on the coordinate input area corresponds to the movement of the marker on the display screen. To provide a coordinate input method and device in which relationships can be freely determined, input operations are easy, and menu areas can be substantially expanded.

(Means for Solving the Problems) In order to solve the above-mentioned problems, the first invention of the present application provides means for transmitting coordinate information to a graphic processing device equipped with a coordinate input device and a display device. In the method of inputting,
The display area of the display device is divided into a plurality of two-dimensional divided input areas formed by dividing the coordinate input area of the coordinate input device, according to processing contents corresponding to coordinate information to be input from these divided input areas. The coordinate information input from the coordinate input device is displayed in correspondence with a plurality of two-dimensional divided display areas, and the correspondence relationship between the divided input area and the divided display area is made variable. Each time the coordinate information is input, it is calculated which divisional input area it belongs to within the coordinate input area, and a marker is displayed at the position of the corresponding divisional display area, and a marker is displayed corresponding to the calculated divisional input area. The attached graphic processing command is input to the graphic processing device.

In order to solve the above-mentioned problems, a coordinate input device provided by the second invention of the present application includes a coordinate input means for inputting two-dimensional coordinate information, and a coordinate input area of the coordinate input means that is divided into a plurality of regions. an area storage circuit that stores position coordinates representing the range of a two-dimensional segmented input area, and a plurality of graphic processing instructions corresponding to the segmented input areas stored in this area storage circuit. a graphic processing command storage circuit; a coordinate conversion circuit for converting the coordinate information input from the coordinate input means into coordinates of the segmented display area; area calculation for calculating to which segmented input area the coordinate information inputted from the coordinate input means belongs based on a display unit to be displayed and positional coordinates of a range of the segmented input area stored in the area storage circuit; circuit and
It is characterized by comprising a graphic processing command execution circuit that receives the output of the area calculation circuit and selects and executes the graphic processing command set in advance in the graphic processing command storage circuit corresponding to the segmented input region. shall be.

(Example) Next, embodiments of the present invention will be described with reference to the drawings.

In the coordinate input method of one embodiment of the first invention of the present application, the first
When the coordinate input area of the coordinate input means is divided into two divided input areas R+ and Rx as shown by reference numeral 11 in the figure, the area of the display screen is correspondingly divided into two divided input areas R+ and Rx as shown by reference numeral 12 in the figure.
As shown, there are two divided regions rl+r! Displayed separately. Then, the correspondence relationship between regions R and rl and region R1
The correspondence relationships between and r are different from each other. For the sake of explanation, an example is given in which the coordinate input area 11 is divided into two divided input areas, but the number of divisions can be set at will. In this embodiment, the ranges of these two regions Rt and R1, and these two segmented input regions R, , R, are displayed on the display screen as a segmented display area! ” I * r 2, as well as region R,
, R, are set and stored in advance. Now, if the coordinates of point P1 in region R1 are input from the coordinate input device, the input coordinate position is converted to coordinate value p on the display screen based on the correspondence between region R, and rl, and the position is changed to By displaying a marker, the operator is informed of the position of the input point, and a graphic processing command is executed when a point within the region R is input. Similarly, point P in R2
, is also a point if input from a coordinate input device? By converting the coordinate position of , into a point p on the display screen and displaying a marker at that position, the operator is informed of the input position, and the graphic processing command assigned to area R2 is executed.

Here, the correspondence relationship between regions R and r and regions R1 and r.

Since the correspondence relationships are not the same, even if the operator performs the same coordinate input operation as shown by dotted lines in the coordinate input areas R1 and R1 as shown in FIG. 2, different markers will appear on the display screen. It is displayed as a movement. Therefore, if it is desired to input highly accurate coordinate information, the coordinate input area should be made to correspond to a wider area on the display screen. On the other hand, if you want to set a large number of areas rather than accuracy,
In other words, if you want to allocate various graphic processing commands as multiple menu items to the coordinate input area, the area on the display screen only needs to be large enough so that visibility is not impaired, and the corresponding coordinates The input area on the input device may be reduced to a size that allows coordinate input for area designation, that is, to the resolution of the coordinate input area.

As described above, according to the coordinate input method of this embodiment, the correspondence between the coordinate input area and the display area on the display screen can be freely set for each screen depending on the purpose, so that the accuracy of coordinate input can be improved. The operating range in which the hand moves, the range in which the marker moves on the display screen, the layout on the display screen including menus, etc. can be freely set according to the use and purpose. Furthermore, according to the coordinate input method of the present invention, the coordinate input area and the display screen are By setting the correspondence with each window area, for example, you can increase the accuracy of coordinate input for the topmost window and enable detailed processing instructions, and then It is also possible to set up the system so that only basic instructions can be given with coarse precision.
