Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Application of the Invention] The present invention relates to a terminal device with a display screen, and more particularly to a terminal device with a rectangular cursor input function having a cursor function using a rectangular window.

[Background of the invention]

In recent years, with the expansion of the field of use of electronic computer systems, including personal computers, and the development of terminal devices that serve as a point of contact between electronic computer systems and users through conversation processing, document processing systems and image processing using electronic computer systems have expanded. The system is becoming popular. This changes the terminal device from the conventional typewriter type to the CRT (Catho
(Ray Tube) As the mainstream of display methods shifted to display screens, there was a shift from displaying only text to drawings that included text,
The fact that it has become possible to display graphs is part of the expansion of its usage. In other words, the user of the terminal device can interact with the τ electronic calculation a system using visual representations.

FIG. 1 is a diagram showing the network system configuration and connection relationships among terminal groups. The host computer 530 has a network configuration with other host computers @ 532 via a communication control computer 531, and the communication control computer 531 of the host computer 530 has a terminal with a CRT display screen (video data terminal) 533 or a terminal control device. (Terminal
A terminal 533 with a CR7 display screen is connected via the Control Elec7ronics) 534. Also,
In addition to the terminal functions of the video data terminal 533, the CR7 display screen terminal (
A personal computer terminal) 535 is also connected.

It is becoming common for the video data terminal 533 and the personal computer terminal 535 to be equipped with a joystick 537, a mouse 538, etc. in addition to the keyboard 536 in order to assist the terminal user in improving operability. A communication control program (NetvorC

540, Operating System
ng System: OS) 541, Communication Management Program (Communication Program)
m: COM) 542, and a large-capacity file 543 connected to the host computer 530 can be freely used.

Furthermore, if the terminal itself has processing capability, such as the personal computer terminal 535, the user of the terminal can perform local processing on the personal computer and execution of the application program 539 on the host computer 530 using the same terminal. It is also logically possible to perform them in parallel.

Measurement data from the measuring instrument 545 is collected via the measuring instrument interface 544 within the personal computer terminal 535 and stored in a file 546.

At the same time, the application program 5 of the host computer 530 is displaying the measured data as a graph on the display screen 547.
In cases where you want to send the data of the file 546 of the personal computer terminal 535 to the personal computer terminal 539 and immediately display the analysis results of the application program 539 on the personal computer terminal 547,
Parallel operation is effective. Furthermore, in general document image processing, it is also conceivable to run application programs 539 and 548 simultaneously using one video data terminal 533. For example, in the application program 548, the document
The application program 548 is in charge of editing processing of documents and graphics. of course,
An application program 539 for creating documents and figures, an application program 548 for editing and copying, etc. may be operated in the personal computer terminal 535 instead of the post computer 530.

The above usage method results in the display screen 547 of one terminal being shared by multiple usage methods. One solution to the method of sharing the display screen of a terminal, C, is a method of controlling the display screen area by dividing it, as disclosed in Japanese Patent Application No. 57-223818.
It is discussed along with its effects. Therefore, the area of the display screen 547 is divided into two parts (top and bottom, left and right), or into four parts (top, bottom, left and right), and the individually allocated areas can be used by application programs separately. Although an effect can be obtained in terms of sharing, an effect can be obtained by dynamically controlling the area using the concept of a rectangle, that is, the concept of a window.

On the other hand, using the concept of a window), it is possible to dynamically set a rectangular area within the display screen 547 and use the set area for other purposes.
The scope of use is greatly expanded compared to a method that statically divides the data. For example, by dynamically changing the size of the area of a window set within the display screen and dynamically changing the size of the window of an application program that uses that window, the terminal user can visually You can freely display the parts you want to process.

Thus, by adopting the concept of windows on the display screen, the visual interface for the terminal user is significantly improved compared to the conventional typewriter system.

By the way, a method for setting windows within the display screen will be explained using FIG. 2.

FIG. 2 shows the configuration of the video data terminal 533 and the personal computer terminal 535 shown in FIG.

The personal computer terminal 535 in FIG. 1 has a display screen 547, a keyboard consisting of a function key section 552 and an alphanumeric/katakana input key section 553, and additional functions such as a joystick 537 and a mouse 538, which control the display and input sections. It consists of

The control circuit section 554 consists of a microcomputer and a memory, under which a control program 555 and processing programs 556, 557, and 558 operate. Control circuit section 55
4 and the display section 547 are connected by a connecting line 559 as an external connection type, or the control circuit section 554 and the display section 547 are integrated and connected by an internal bus. They are functionally the same. actually,
The processing program 556 uses the display screen 547 to perform instrument control and document/image processing, and the processing program 558 communicates with the host computer 530 in FIG. The display screen 547 is shared by controlling the display screen of the running application program 539 and using a window 551 within the display screen 547. In the case where the configuration of FIG. 2 is the video data terminal 533 shown in FIG. There is only one processing program, and its processing program also performs a communication function with the host computer 530.

Referring to FIG. 2, to set the conventional window 551, first move the cursor (indicated by +) to position 561, press down the function key 552, and then press position 561.
By positioning the cursor at point 62 and pressing down any of the function keys 552 again, line segments 563 to 566 are displayed so as to surround the diagonal line with a rectangle, thereby determining the window area. These processes are performed by a display screen management program (not shown) within the control program 555. Note that the joystick 537 or mouse 538 may be used instead of the function keys to move the cursor or specify the position within the display screen.

Here, when dynamically changing the size of the window, the terminal user must first set the position 561 by
Two operations are required to move the cursor position and press down the function key, and similarly, two operations are required to set the position 562, for a total of four operations.

Although the point of contact between electronic computer systems, including personal computers, and the users who use them has changed from the textual representation of typewriter terminals to the visual representation of terminals with display screens, the number of operations has decreased. There's a problem.

[Purpose of the invention]

It is an object of the present invention, in order to solve the above-mentioned conventional problems, to specify the window position within the display screen only once, automatically set the size of the window area to the size desired by the terminal user, and adjust the window line. An object of the present invention is to provide a terminal device with a rectangular cursor input function capable of displaying minutes.

Another object of the present invention is to change the window starting point address value in the display screen from the starting point in the X-axis direction in the A direction, to automatically set the size of the window area.
It is an object of the present invention to provide a terminal device with a rectangular cursor input function that can quickly set a window by having a counter that counts the area width in units of pitch in the direction.

[Summary of the invention]

In order to achieve the above object, the terminal device with a rectangular cursor input function of the present invention converts the address in the display screen when setting the window starting point from the keyboard, joystick or mouse to the address value in the X-axis direction (pixel address), A control circuit that holds the address value in the axial direction (pixel address),
When a command is issued to determine the window area size after setting the window starting point address, a support control circuit is installed to automatically draw a rectangle using the window starting point address as the starting point by providing a counter corresponding to the number of pixels moved according to the amount of movement. The terminal is equipped with a control circuit that subtracts the end point address of the window after the window area is determined, and passes the above window start point address, end point address, and window width value in response to a request from the application program. This reduces the number of operations required by the user to specify a window, speeds up window settings, and controls the display of line segments in the window area separately from the process of displaying image data on the display screen. The present invention is characterized in that it is equipped with a circuit and can display line segments in a window area without destroying image data to be displayed.

[Embodiments of the invention]

Hereinafter, one embodiment of the present invention will be described in detail using the drawings. FIG. 1 is a diagram showing a network configuration of a computer system to which the present invention is applied, and a configuration in which a video/data terminal and a personal computer terminal are connected to the computer system. In FIG. 1, the terminal device with a rectangular cursor function of the present invention is applied to a personal computer terminal 535 and a video data terminal 533.

In the following description, an example applied to the personal computer terminal 535 in FIG. 1 will be used. Of course,
The terminal device with a rectangular cursor function of the present invention, when the scale of data processing can be performed only on the personal computer, such as a personal computer terminal, is provided with a host computer 530 and a personal computer terminal 53.
5 is not an essential condition.

FIG. 2 shows the display screen 54 of the personal computer terminal 535 in FIG.
FIG. 7 is a diagram showing a specific appearance when setting a window in No. 7, centering on the display screen and keyboard input section. Reference numerals 551 to 566 in FIG. 2 have been previously explained. 5
Reference numeral 67 denotes a cursor movement designation key added to the keyboard, which is added to conventional terminal devices. The cursor movement instruction keys 567 are used to instruct the direction when moving the cursor position 1561 up, down, left and right, and are made up of four keys (DI?) as shown in the figure. When one of the function keys 552 is pressed when the cursor is positioned at the position, the cursor position address value at that time is passed to the processing program.Therefore, conventionally, the starting cursor position 561 of the window is
and the target end point cursor position w562 were specified separately.

In accordance with the present invention, a group of window designation keys 568 to 571 are set on the keyboard section. 568 is a window area enlargement instruction key, and 569 is a window area enlargement operation stop key.

570 is an enlargement instruction key in the X-axis direction, and 571 is an enlargement instruction key in the Y-axis direction. Enlargement instruction key 570.571
If the area enlargement instruction key 568 is pressed without pressing both, the area will be enlarged in both the X-axis and Y-axis directions.

In addition to using the special keys on the keyboard mentioned above, the window area can also be specified using the joystick 537.
Alternatively, a method using the mouse 538 is also possible.

In the case of joystick 537, joystick 53
When 7 is moved vertically, horizontally, or diagonally, the window starting point cursor 561 also moves accordingly. The button 572 at the end of the joystick 537 generates a control signal to set the window starting address, and the button 57
If you keep pressing 2, the window starting point address 561 is assumed to be the top of the left corner of the window area, and line segment 5 is automatically set.
63 to 566 draw a square rectangle, and the rectangle grows until the button 572 is released.

Therefore, the terminal user can visually monitor and release button 572 when the desired window size is reached. Also, the horizontal button 573 located next to the joystick 537 is used to stop the expansion of the window by the square rectangle described above.
73, tilting the joystick 537 in the X-axis direction will cause line segment 563 and line segment 5 on display screen 547 to
66 is displayed in the Y-axis direction, and line segments 566 are sequentially expanded in the X-axis direction. At this time, line segment 563 and line segment 566 are displayed from the top end to the bottom end of display screen 547. Next, when the joystick 537 is tilted in the Y-axis direction, the line segment 56
4 and a line segment 565 are displayed, and the line segment 564 expands in the Y-axis direction. Once the desired window size is obtained, the terminal user can release the pressed button 572. Also, the joystick 537 is used to rotate the window.
Turn the button to rotate the displayed window.

On the other hand, the basic operation of specifying a window using the mouse 538 is the same as that of the joystick 537.

That is, when the mouse 538 is moved on a plane, the window starting point cursor 561 moves accordingly, and when the button 574 is pressed, the starting point of the window is determined. The button 575 is a button for instructing automatic enlargement of a square window, and the button 576 is a button for instructing unidirectional movement in the X-axis or Y-axis direction, and its operation method is the same as that of the joystick 537 described above.

Therefore, the terminal device with a rectangular cursor input function of the present invention automatically enlarges the rectangular size of the window until it reaches the window size desired by the terminal user, thereby reducing the number of operations by the terminal user by 2. This feature is unique in that it only takes a few times. 3 to 5, the operation control and operation method of the present invention will be described using a terminal device to which a joystick 537 is attached as a specific example.

Joystick/Mouse Interface In times Fj&1, Joystick 53
7, a control signal enters the joystick/mouse interface circuit 1 via the signal line group Q1, and from the joystick/mouse interface circuit 1, the moving pixel interval amount in the X-axis direction is sent to the signal line Q2. , a discrimination signal for the positive direction or the reverse direction of the X-axis is output to the signal line a3. Here, if the value of the signal line ρ3 is ah 1 Tr, it means movement in the positive direction. Similarly, the signal 1JAQ4 is outputted as the amount of pixel interval movement in the Y-axis direction, and the signal line f15 is outputted as a discrimination signal indicating whether or not the movement is in the positive direction of the Y-axis.

Furthermore, the signal @Q6 is connected to the addition/subtraction circuits 4 and 6 and the counter 1.
A signal that controls the operations of 1 and 12 is output, and if the signal value is '0'', it instructs the operation of the addition/subtraction circuits 4 and 6, and if the signal value is rz 1 rr, it instructs the operation of the counters 11 and 12.

Reference numeral 31 is a delay circuit of, for example, 10 microseconds, and reference numerals 32, 33 and 34 are differential circuits. Here, the circuits 25, 33, and 34 are processing circuits for control signals from the mouse 538, and are used for other purposes.

By tilting the joy snack 537 in the X-axis direction or Y-axis direction, the signal line l1lo.

The coordinate values are input to the movement amount calculation circuits 22 and 23 via Qll. The value of X-REG5 in FIG. 4 is input to the movement amount calculation circuit 22 via the signal line Q8, and the direction of the X-axis is determined by the difference between the value of the signal line Q10 and the value of the signal line Q8. It will be done. If the movement is in the positive direction of the X-axis, the value of the signal line i3 is 1''. Also, a level signal indicating the movement of the cursor position is output to the signal line ρ13. Movement of the cursor position occurs, signal 1
The value of iAQ 13 becomes # 14g, and AND circuit 27
becomes the input. The AND circuit 27 performs an AND operation between the pulse signal output from the timing generation circuit 29 and the signal line Ω13, and outputs the result via the signal line ρ2. Therefore, the signal on signal line Q2 represents the number of pixels of cursor movement in the X-axis direction.

Further, in the timing generation circuit 29, after the button 572 is pressed, the analog/digital conversion circuit 24 outputs the signal ls! An acceleration command signal is output via aΩ14, and the interval between pulse signals from the timing generation circuit 29 becomes shorter, and as a result, the pitch interval of the movement of the signal line Q2 in the X-axis direction becomes shorter, allowing high-speed coordinate movement. Can give instructions. Y l1ll by movement amount calculation circuit 23 and AND circuit 28
The movement control in the jj direction is performed in the same manner as the movement control in the X-axis direction described above. That is, a movement pitch in the Y-axis direction is output to the signal line β4, and a movement signal in the forward direction (the value is rr 1 u) or in the reverse direction (the value is “O”) is output to the signal line Q5. When joystick 537 is tilted diagonally, signal line Q2. A movement amount pitch signal is output to Q3.

Note that when the button 573 is pressed and the joystick 537 is moved, movement in either the X axis or the Y axis is blocked.

When the button 572 is pressed down, an analog signal is excited in the signal line Q12, and the analog/digital conversion circuit 24 is activated. As a result, the value of flip-flop 3O becomes "1"
``Well, signal line μ7 has a rigger signal, and signal line a
A mode signal is outputted to the signal line Ql6 through the delay circuit 31, and the value of the signal becomes "1". The value is set to 1''. The signal line Q1G is connected to the display output control 611 in FIG. 3, which instructs the display output control 611 to draw a rectangular line segment.

Referring again to FIG. 4, the cursor address calculation circuit 2
Then, the position of the cursor position in the X-axis direction is calculated sequentially, and the value is held in X-REG5. Similarly, the calculation results by the cursor address calculation circuit 3 are Y - R, E
G is held at 7. Therefore, X-REG5. Y
- The value of REG7 represents the cursor position on the joystick 537 [1 movement command, the window starting position on the display screen 547, and the value of this child is the signal line ρ20
The signal 2L is outputted to the display control section 611 in FIG. 3 via .OMEGA.21. Display Rr! In the hole portion 61), a cursor is displayed on the display screen 547 based on this value.

This display operation is performed independently of the display operation of pixel data in the display memory 613 in FIG. 3.

Once the terminal user has determined the window starting position on the display screen 547, he or she may press the button 572 on the joystick 537. This causes the value of signal line 126 to become II
Oj, becomes II l II, and the operation of the cursor address calculation circuits 2 and 3 is stopped. In addition, the value of the signal line Q7 and the value of Ω16 become "1", and the X-axis direction window width counter (X-C) 11 is set by the signal of the signal line j17.
, the Y-axis direction window width counter (Y-C) 12 is reset. Also, the signal on the signal line Q16 causes the third
The display control unit 611 in the figure starts displaying line segments of the frame of the window 551 as shown in FIG. In this case, a square window frame will be automatically created.

(While the value of the d quantity line Ω6 is 111 H, the movement amount pitch value in the X-axis and Y-axis directions is sent to the signal line Ω2. The window width counter (X-C) 11 and the Y-axis direction window width counter ('Y-C) 12 are counted up6.

Once the terminal user visually confirms the desired window frame, the terminal user can release the pressed state of button 572. As a result, the value of signal af16 becomes II 071,
The 4 mm cotton wire Ω6 signal passes through a delay circuit 15, an inversion circuit 1O, and a differentiation circuit 16, and instructs the adder 3°14 to start operating. The adder 13 adds the values of the X-axis cursor position register (X, -REG) 5 at the window start point and the XIM direction window width counter (X-C) 1.1.
