For example, when designing a pattern using CAD (Computer Aided Design), conventionally, as shown in Figure 1, there is a menu item M necessary for selecting a function function outside the display area D for designing on the display 1. ₁ , _M2 ... _M3 are displayed. In this case, the display screen coordinates on the display 1 correspond to the input coordinates on the tablet 2 on a one-to-one basis. In other words, the design area of Tablet 2
D′ corresponds to display area D on display 1,
The menu areas M' ₁ , M' ₂ . . . M' _o on the tablet 2 are replaced by the menu items M ₁ , M ₂ ,... _M
It corresponds to For example, if the menu item _M'1 is an item to be deleted, after touching the menu item _M'1 on the tablet 2 with the coordinate detection pen 3, in the design area D' of the tablet 2,
By specifying the displayed figure to be deleted, for example _P1 , this displayed figure _P1 can be deleted.

In addition, in the case of Fig. 1, the menu items are only pre-input M ₁ to _{M o} , so if you want to further increase the number of menu items, prepare a menu sheet MS as shown by the dotted line in Fig. 2 and display it. For example, display menu items M ₁ to _{M o} on the top, enter one of M ₁₁ to _{M no} to enter menu sheet input mode, and select menu items M ₁ to M _o , M ₁₁
~M It has been done to select _no .

However, the following problems exist in the devices illustrated in FIGS. 1 and 2.

(1) A menu area must be set aside as part of the display screen, so the display area D for graphics is required.
decreases, and you cannot select many menu items.

(2) Drawings of any size within the design area D', which is the input area of a coordinate input device such as the tablet 2, cannot be input in correspondence with the display screen.

(3) It is not possible to know the coordinates of the coordinate input device.

(4) As shown in FIG. 2, in the case of a multi-item sub-menu input method using a menu sheet, two steps, a coordinate input mode and a menu input mode, are always required.

[Embodiment of the Invention] Before describing the present invention in detail based on one embodiment, an outline thereof will be explained based on FIGS. 3 and 4.

In the present invention, as shown in FIG. 3, a coordinate input device 11 such as a tablet is used to input an input area d, such as a graphic input area, and a plurality of menu areas m' ₁ to m' ₄ that are defined in advance. As shown in FIG. 4, the display on the display 10 displays the input area d.
When a part within the input area d is selected with the pen R, this is displayed as shown by the marker MA, and when one of the menu areas is selected, the selected area is the menu area. It identifies the selection and performs processing according to the selected content. In this case, the coordinate input device has a menu sheet prepared according to the content to be executed, and is operated to input figures, select a menu area, etc. from the menu sheet. Since the contents of each menu sheet are registered in advance in the memory of the host, the input area for menu areas, figures, etc. can be determined by inputting the identification (address) code of the menu sheet prior to operation. By doing this, as shown in FIG. 4, the display 10 can accommodate the entire display screen area, which is the input area for drawings, etc., without displaying menu items. Not only can input data be displayed in large size and in detail, but also various menu items can be easily selected.

The configuration of one embodiment of the present invention will be described with reference to FIGS. 5 and 6 and other figures.

FIG. 5 is a block diagram of a graphic processing system representing an embodiment of the present invention, and FIG. 6 is an explanatory diagram of its operation.

In the figure, 10 is a CRT-like display, 11
1 is a coordinate input device such as a tablet; 12 is a keyboard; 13 is an interface control unit; 14 is an arithmetic processing unit; 15 is a memory; 16 is a display control unit;

Reference numeral 20 denotes a graphic display processing device which includes the above-mentioned display 10 to display control section 16 and the like.

The display 10 and coordinate input device 11 are the same as those shown in FIGS. 3 and 4.

The coordinate input device 11 is used to input a display screen to be displayed on the display 10 and to select a menu item as a function. The coordinate input device 11 uses a menu sheet depending on the content to be processed at that time. This menu sheet has a menu area outside the input area d for inputting the display screen of figures, etc.
m′ ₁ to m′ ₄ are provided, and each menu area m′ ₁ to m′ ₄
has multiple menu items defined.

The keyboard 12 is used to input, for example, the identification code of the menu sheet being used at that time.

The interface control unit 13 is the coordinate input device 1
1 or the keyboard 12 and transmits it to the arithmetic processing unit 14 or the host processing unit 17, or the arithmetic processing unit 1 in response to these inputs.
The data processed by 4 is sent to the host processing device 17 or the like.

The arithmetic processing unit 14 operates as a coordinate conversion means. That is, it performs calculations for coordinate transformation in order to make the coordinate data input from the coordinate input device 11 correspond to the position on the display 10.

This calculation is performed as follows.

As shown in FIG. 6, point A (X _A , Y _A ) on the coordinate input device 11 is made to correspond to the origin 0 of the display screen of the display 10, and point B (X _A , ΔX, Y _A +
ΔY) is displayed in correspondence with point P on the display 10. The width of the graphic display area d in the X direction is ΔX, the width in the Y direction is ΔY, and the width in the X direction on the display 10 is X _Max. , the width in the Y direction is Y _Max , and the coordinates of the input point T by the input pen are (X _T , Y _T ), then the coordinates of the display point S on the display 10 corresponding to this input point T are (X _S , Y _S )
The conversion operation is performed as follows.

(a) Conversion in the X direction When X _A ≦X _T ≦X _A +ΔX X _S =X _T −X _A /ΔX・X _Max ...(1) When X _A > X _T or X _{T > X S = Address indicating outside the display screen =} ＞Y _T is Y _T ＞Y _A + ΔY When Y _S = Address indicating outside the display screen = Y _OUT memory 15 stores the above ΔX, _{ΔY ,} It holds data.

The display control section 16 performs various controls for displaying on the display 10.

The host processing device 17 identifies whether the pen input coordinates are a display screen area or a menu area, and if the pen input coordinates are a menu area, identifies which menu area it is, and inputs the input coordinates (X _T , Y _T ). The host processing unit 18 and the host memory 19 are configured to search for a menu item corresponding to a menu item and perform corresponding control. The host memory 19 holds data on various menu sheets, that is, display screen areas, menu areas, menu items, and input data input from the display screen area d. The host processing unit 18 stores data input from the coordinate input device 11 and the keyboard 12 in the host memory 19, or performs various controls based on the data input from the coordinate input device 11.

Next, the operation of the present invention will be explained.

(1) Prior to operation, the operator sets a menu sheet corresponding to the content to be executed on the coordinate input device 11, and inputs the identification (ID) code of the menu sheet from the keyboard 12. This identification number is sent to the host processing device 17 via the interface control section 13. Thereby, the host processing device 17 determines the menu sheet used by the coordinate input device 11.

(2) Next, the operator activates the coordinate input device 11. By this activation, the entire area of the coordinate input device 11 is set to a default state so as to correspond to the display screen of the display 10.

(3) Next, the host processing device 17 instructs a coordinate input command, and when points A and B in FIG. 6 are input with the pen down, the coordinates of these points A and B are sent to the host processing device 17. A display screen area d is defined. Also, by specifying the display screen area definition command from HOST, memory 15
Point A (X _A , Y _A ) and (ΔX, ΔY) are stored in .

(4) Next _, the operator inputs a command from the keyboard 12 to start the menu area setting program, and selects the two points ( _{A 1 ,} B ₁ ), ( A ₂ , B ₂ )...,
The coordinate data is sent to the host processing device 17.
The menu area is defined using this coordinate data.

(5) After the display screen area and menu area are defined in this way, the operator uses the display screen area to perform graphic processing. Coordinate data (X _T , Y _T ) of point T inputted with the pen R to the coordinate input device 11 during this graphic processing
is sent to the arithmetic processing unit 14. And these X _T and Y _T are both X _A ≦X _T ≦X _A +ΔX, Y _A
In the case of ≦Y _T ≦Y _A +ΔY, the point pen-downed by the pen R is within the display screen area d, so the above equations (1) and (2) are calculated. Then, the display control unit 16 for the calculation results X _S and Y _S
The data will be sent to and displayed on the display screen of the display 10. And this X _S , Y _S and X _T ,
Y _T is sent to the host processing device 17 in a format as shown in FIG. 7, for example. The host processing unit 18 looks at X _S and Y _S and determines whether these are X _put ,
Since it is not Y _put , it is recognized that the input was made using the display screen area d, and these X _T and Y _T are held in the host memory 19 as display data.

(5) However, when the operator presses the pen down on a menu item on the menu sheet to select a function, the arithmetic processing unit 14 determines whether the input point (X _T , Y _T ) is X _A > X _T or X _T > X _A +ΔX or Y _A > Y _T or Y _T > Y _A +ΔY is detected, and accordingly X _S or X _put or
Send it to the host processing device 17 as Y _put . The host processing unit 18 applies X _put to this sent data.
or Y _put is input, it recognizes that the pen down part is a menu area, identifies which menu area it is by the input point (X _T , Y _T ), and The menu items corresponding to _T and Y _T are read from the host memory 19. Then, control is performed using the function specified in this menu item.

As described above, according to the present invention, by defining two input areas, the display screen area and the menu area, and simultaneously sending out the display screen coordinates and the coordinates of the coordinate input device, the following becomes possible.

(b) The menu area does not necessarily have to be a part of the display screen, and the entire display screen can be used for graphical display.

(b) Since display screen coordinate input and menu input can be recognized using input coordinate data, there is no need to switch between coordinate input mode and menu input mode.

(c) It is possible to input drawings of any size within the input area of the coordinate input device in correspondence with the display screen.

[Background of the invention]

According to the present invention, since the coordinate input area can be arbitrarily defined in the display screen area and the menu area, the display screen can be used effectively and coordinate input can be performed with good compatibility with the display screen. Moreover, since the operator can select and input menu items from the coordinate input device without looking at the display screen, menu input can be performed with good operability. Furthermore, since the graphic display processing device and the host processing are separated and the menu items are identified and extracted in the host processing device, the burden on the graphic display processing device is extremely small, and input pen tracking processing can be performed efficiently. becomes possible.
