The present invention relates to a cursor display device,
In particular, the present invention relates to a cursor display device and a cursor display method for moving and displaying a CRT screen in response to movement of a mouse or the like in a personal computer or various information processing terminal devices.

[0002]

2. Description of the Related Art Usually, a cursor is used for selecting display information by moving a CRT screen in accordance with the movement of a cursor display device and positioning items, parameters, and function names displayed on the CRT screen.

The above-described functions are generally used in personal computers as basic functions (operations) of windows.

As the above-described cursor display device, a device whose basic type is shown in FIG. 5 is widely used in the past. Normally, when an instruction or data is input from the keyboard 3, the keyboard control unit 4 recognizes the instruction or data from the keyboard 3 and transfers the data to the processing device 2. The processing device 2 instructs the CRT control means 6 to display on the CRT 5 based on the data from the keyboard control means, and the CRT control means 6 displays on the CRT 5 of the display according to the instruction. On the other hand, in order to display the cursor, the movement of the mouse 7 is detected by the position information
The cursor position information is transmitted to the processing device 2 via the position information control means 11, and the movement of the mouse is also transmitted to the position information output means 10. The position information output means 10 instructs the cursor display means 8 on the position coordinates of the cursor according to the movement of the mouse 7, and displays it on the CRT 5 via the CRT control means 6.
Further, since the mouse 7 is usually provided with a switch button, the processing device 2 determines an instruction request based on the relationship between the position of the cursor and the display position according to the depression of the switch button, and follows the instruction request. Execute the process.

In this way, the position of the cursor is always recognized while the operator continues to operate, and necessary processing and
Alternatively, input of characters or the like can be executed. However, display screens such as windows have a complicated and large display content, and accordingly the cursor as a pointer has also become smaller, so that when resuming operation after interrupting a temporary operation, it may take time to find the location of the cursor. is there. As a countermeasure against such a problem, (1) an image processing apparatus

Another object of the present invention is to provide a cursor position control method using a mouse that can easily find a cursor because a cursor is displayed at a preset initial position when the work is resumed after a predetermined time has elapsed.

The above (3) is an unused state in which the mouse cursor is displayed at the same display position for a predetermined time or more by providing a device for recognizing the display position of the mouse cursor and a device for recognizing the elapsed time. The mouse cursor is enlarged, the display color / shape is changed, or blinking is performed so that the user can immediately recognize the position of the mouse cursor when resuming use. When the operation is continued, the original display shape, size, and color are restored to make the display suitable for continuous operation.

[0009]

In the above-mentioned prior art, in the case of the above (1), it is necessary to move the mouse according to a rule determined for highlighting the mouse cursor, which is troublesome. Further, in the case of the above (2), even if the operator wants to resume use from the target position, the mouse cursor moves to a fixed position, so that it is troublesome to move the mouse cursor to the target position every time the use is resumed. I was Further, in the case of the above (3), simply changing the color or shape of the mouse cursor does not make it easy to see depending on the condition of the display screen, because the Windows screen is increasingly complicated and large.

The reason is that various lines and patterns exist in C.
In general, it is difficult to find a small cursor at a glance by simply changing the color or shape without taking any trouble on the RT screen.

The object of the present invention is to solve the above-mentioned drawbacks and to make it easier to find the position of the cursor in the stationary state by returning to the original position when resuming use without trouble. , A cursor display device.

The detecting means 20 is a control means. The personal computer 1 includes a processing device 2, a CRT 5 serving as a display unit, a CRT control unit 6, and the like, and is the same as the personal computer 1 in the above-described conventional technology (FIG. 5). Further, although the range showing the personal computer 1 is surrounded by a broken line in FIG. 1, this does not delimit the range of the present embodiment, merely showing the same range as that of the prior art. In addition, the storage unit 18 includes the position storage unit 12 and the division point storage unit 15.
And interval storage means 17.

In the first embodiment, when there is no input signal from the keyboard 3 for a certain period of time, the control means 20 controls the position storage means 12 via the keyboard control means 4 and the state detection means 19.
The position change detecting means 13 and the like are controlled, and the original position of the cursor and the position after enlargement when the cursor is displayed at an arbitrary position on the full screen are stored in the position storage means 12. Next, the original position of the cursor and the position after the enlargement are connected by a straight line, divided into N (N is an arbitrary positive integer), and divided point storage means 15
To memorize. Then, the cursor enlarged display means 16 displays the information on the CRT 5 based on the information in the storage means 18. On this occasion,
The output of the CRT control means 6 is turned off and displayed. The output of the cursor enlarged display means 16 is input to the CRT 5, but is input to the CRT control means 6 to display the output of the cursor display means 8 and the output of the cursor enlarged display means via the signal switching means. May be.

FIG. 3 shows a flow chart of the position change detecting means 13, the division point detecting means 14, the cursor enlarged display means 16, and the state detecting means 19.

Next, the operation of the cursor display device will be described. The state detection means 19 provided with a timer monitors whether there is no input signal from the keyboard 3 for a predetermined time via the keyboard control means 4 (S1). Next, state detection means 19
Cursor after informed that there is no fixed time input signal to the control means 20 from the keyboard 3 (S2), the position storage section 12 based on the cursor position in the lower left corner of the screen (X _1, Y ₁₎ and the screen in the middle expanded from The position (X ₂ , Y ₂ ) is stored (S3). Further, the position change detecting means 13 calculates a straight line connecting the original cursor position and the enlarged cursor position (S4). This straight line is expressed as Y = {(Y ₂ −Y ₁ ) / (X ₂ −X ₁ )} X + {(X ₂ Y ₁ −
X ₁ Y ₂ ) / (X ₂ −X ₁ )}.

Next, the dividing point detecting means 14 divides the straight line calculated by the position change detecting means 13 into, for example, 10 (S
5) The 11 positions are stored in the division point storage unit 15.
(S6). Thereafter, when the state detecting means 19 is notified that an input signal has been generated again from the keyboard 3 or the like (S7, S8), the cursor enlargement display means 16 divides the cursor position after the enlargement from the original cursor position into ten parts (S7). S9). In this case, when the maximum cursor length is L, the length of each cursor is calculated by calculating the length corresponding to the number of divisions N as shown in FIG. The length of each cursor is (1) L, (2) {(N-1) / N {L, (3)} (N
−2) / N｝ L, (4) (2 / N) L, (5)
(1 / N) L.

The value of the length L of the maximum cursor may be a value obtained by multiplying the value of the length of the original cursor by a plurality of times. I just need. The cursor position is displayed on the CRT 5 at the time stored in the interval storage means 17 at the position stored in the division point storage means 15 (S10). By observing the state change that gradually decreases from the enlarged cursor in this way and converges to the original cursor position, the original cursor position can be clearly recognized, and there is no need to operate a meaningless mouse, etc. Even if various lines and patterns exist on the CRT screen, the cursor can be easily found.

In the present embodiment, the screen saver or the power saver may be in a state after a lapse of a certain time until a one-touch operation with a mouse or a keyboard is performed. Also, as shown in FIG. 2, the case where the original cursor position is located at the lower left position has been described, but this position may be located at any position on the screen. For example, the original cursor position is located at the center of the screen. Even if it is located, if there is one touch of a keyboard or the like, the cursor is gradually reduced at the same position from the enlarged screen of the cursor, so that it can be immediately recognized that the cursor is at the center on the screen.

The shape, size, color, etc. of the cursor may be such that the indicated point is clear on the display and the outline thereof is clear. The cursor indicates where the cursor is, regardless of the shape or color of the cursor. It is only necessary to use an index having a high visibility, and it is preferable that only the outline of the hollow part is displayed as an encircling line and the display area of the cursor on the screen is small.

[Second Embodiment] FIG. 4 is a block diagram showing a cursor display device according to a second embodiment of the present invention.
When there is no output signal for displaying data or the like on the CRT 5 for a certain period of time, the state detecting means 19 operates via the CRT control means 6, for example, maintaining other display states in conjunction with a predetermined power save display, and keying the input means. When a touch or a mouse operation is input, a trigger signal is output from the state detection unit 19 to the control unit 20, and the same processing as in the above-described first embodiment is performed.

In the above description, the state detecting means 19
Has a timer for monitoring information from a keyboard, a mouse, a CRT, or the like for a certain period of time. However, a timer of the processing device 2 may be used. Further, the interval setting of the interval storage unit 17 is not fixed, and the user may arbitrarily set the interval storage unit 17 from the outside. Further, a straight line is calculated by the position change detecting means 13, but may be a curve or the like.

[Third Embodiment] When the machine is not used for a certain period of time and the machine is used again, the mouse cursor is enlarged and displayed on the screen. After that, the enlarged mouse cursor gradually reduces and returns to the original shape (position). By looking at it, the position of the mouse cursor can be easily confirmed.

FIG. 6 is a flowchart showing the operation processing of the cursor processing of this embodiment. First, a process of obtaining the mouse movement amount / button press information is performed (S11). The operation state of the mouse is monitored, and a process for enlarging / reducing the mouse cursor is performed if the mouse is not operated for a predetermined time (S
12). Next, a process of checking the amount of movement of the mouse is performed (S13). If the mouse cursor has been moved, a process of moving the cursor by the moving amount is performed.
(S14). If the mouse cursor has not been moved, a process of checking the pressed state of the mouse button is performed (S15). When the mouse button is pressed, a process of notifying the information of the pressed mouse button to another program is executed (S16).

FIGS. 7 and 8 show state diagrams of this embodiment. That is, when there is no key touch from the input means such as the keyboard or the mouse for a certain period of time, the mouse cursor process starts, and by adding the process of step 12 in FIG. 6, the mouse cursor is first moved as shown in FIG. The image is enlarged and gradually reduced, and is displayed in the original shape at the original cursor position as shown in FIG. 8, making it easy to confirm the position of the mouse cursor.

[0031]

In the cursor display device, when there is no operation of a keyboard, a mouse, or the like for a certain period of time, the cursor is first enlarged and then gradually reduced, so that the small cursor can display various lines or lines on the CRT screen. Even if it exists in the pattern, it can be easily found. Therefore, there is no need to perform a meaningless mouse operation. In this way, by seeing the magnifying cursor gradually shrink,
The position where the cursor converges can be visually recognized.
