Abstract

PURPOSE:To improve the operability by erasing a pointing cursor when the pointing cursor overlaps with a character cursor at the time of character input. CONSTITUTION:When a character is inputted from a keyboard 3, an input/output control circuit 5 checks which window area the pointing cursor is present in by referring to the contents of a window control memory 11 according to the contents of a pointing cursor position register 13, and decides the window where the pointing cursor is present as an input object. Then, a position comparing circuit 14 compares the contents of a character input position control memory 12 with the contents of a cursor position register 13 and outputs a position coincidence signal to an input control circuit 5 when the display of the pointing cursor overlaps with that of the character cursor. The input control circuit 5 puts a timer 15 in operation on receiving the signal and instructs a CRT controller 6 to display data to be displayed stored in a stand-by memory 10.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a display display device, and more particularly to a display display device for inputting with two types of cursors, a character cursor and a pointing cursor.

[0002]

2. Description of the Related Art Conventionally, a display device, which is a terminal of an information processing device such as a computer, displays input characters such as a multi-window display device that displays a plurality of window screens on one display device. In addition to the character cursor indicating the position, a pointing cursor is used to display the position of the point coordinates on the display screen.

For example, in a multi-window display device, the pointing cursor moves its position on the display screen by operating a pointing device such as a mouse, and in the case of character input, the position of such a pointing cursor. The window being input becomes the input target window.

The control of the cursor in such a display device is disclosed in Japanese Patent Laid-Open No. 63-103289.
Japanese Patent Laid-Open Publication No. 2004-242242 describes a technique for automatically displaying a character cursor at a character input position.

However, in such a conventional display device, since the two cursors, the character cursor and the pointing cursor, are mixed, the character cursor moves during the inputting work and becomes the pointing cursor. If they overlap, it becomes difficult to check the characters that are being input on the screen, and the operability deteriorates.

[0006]

SUMMARY OF THE INVENTION The present invention has been made in view of the above circumstances, and an input operation is performed in a display device in which two cursors, a character cursor and a pointing cursor, are mixed. An object of the present invention is to provide a display display device that does not make it difficult to confirm a character being input on the screen when the character cursor moves during the movement and overlaps with the pointing cursor.

[0007]

A display device according to the present invention comprises a display management means for storing a display area on a display screen, a character input position management means for storing position information for character input. Cursor position storage means for storing the display position of the pointing cursor, cursor position comparison means for comparing the character input position with the pointing cursor position, and timer means for counting a predetermined time when the character cursor overlaps the pointing cursor. , And the pointing cursor is erased while the timer means is counting a predetermined time.

[0008]

According to the display device of the present invention,
When the cursor position comparing means determines that the character cursor at the position indicated by the character input position managing means and the pointing cursor at the position indicated by the cursor position storing means are overlapped with each other, the timer means sets a predetermined time. While the counting is performed and the counting is performed by the timer means, the pointing cursor is not displayed at the position indicated by the cursor position storage means. When the counting of the predetermined time by the timer means is completed, the pointing cursor is displayed at the position indicated by the cursor position storage means.

Embodiments of the present invention will be described below with reference to the drawings.

FIG. 1 is a schematic configuration diagram of an embodiment of an information processing apparatus for performing multi-window display using a display display apparatus according to the present invention. In FIG. 1, (1) is a CPU that controls the information processing apparatus, and (2)
Is a main memory in which a control program or data of the CPU (1) is stored. Reference numeral (3) is a keyboard as a key input means, and reference numeral (4) is a mouse as a pointing device, both of which are connected to an input / output control circuit (5) which controls the display display device.

(6) is a CRT controller for controlling display data, display timing, etc. on the CRT (7), (8) is a font memory for storing a character pattern, and (9) is a character cursor pattern. And a cursor pattern generation circuit for generating a pointing cursor pattern, and (10) is a save memory for temporarily storing the original display data of the portion where the cursor is displayed when the cursor pattern is displayed.

(11) is a window management memory for storing a plurality of window areas on the CRT (7) screen, and (12) is a character input position management memory for storing character input position information for each window to be displayed. And (1
Reference numeral 3) is a pointing cursor position register which stores a designated position on the CRT (7) of a pointing cursor which moves in response to the operation of the mouse (4).

(14) is a character input position management memory (1
A position comparison circuit for comparing the position information of 2) with the position information of the pointing cursor position register (13), wherein the character cursor and the pointing cursor are CRTs.
(7) When they overlap each other on the screen, a time-up signal is output when a predetermined time (for example, 10 seconds) has elapsed since the timer (15) started counting.

FIG. 2 shows how characters are input to one of a plurality of windows on the CRT (7) screen. In FIG. 2, (20-A, B, C),
(2 indicates a character cursor, and (21-A, B) indicates a pointing cursor.

Now, it is assumed that two windows are displayed on the CRT (7) screen. The window areas of these windows are stored in the window management memory (11). Further, as shown in FIG. 2A, input is being made in one of these two windows.

The pointing cursor (21-A) is displayed in the window in which the input is made, and its display position is stored in the cursor position register (13). The indication of the pointing cursor (21-A) is C
The RT controller (6) takes out the pointing cursor from the cursor pattern generation circuit (9) and displays it at the display position stored in the cursor position register (13). While the pointing cursor (21-A) is displayed, the pointing cursor (2
The display data on the window corresponding to the display portion 1-A) is stored in the save memory (10).

The character input position management memory (12) stores the character input position in each window.
The character cursor (20-A) is displayed by the input / output control circuit (5) according to the contents of the character input position management memory (12).
Causes the CRT controller (6) to retrieve the cursor pattern from the cursor pattern generation circuit (9), and
It is performed by displaying in (7).

Now, when a character is input from the keyboard (3) on the display screen in the state as shown in FIG. 2A, the input / output control circuit (5) is based on the contents of the pointing cursor position register (13). , The window management memory (11) is referred to check which window area the pointing cursor is in, and the window having the pointing cursor (21-A) is set as an input target.

Subsequently, the position comparison circuit (14) includes a character input position management memory (12) and a cursor position register (1
The contents of 3) are compared, and as shown in FIG. 2A, the pointing cursor (21-A) and the character cursor (20-
When the displays in A) overlap, a position coincidence signal is output to the input control circuit (5).

In response to this, the input control circuit (5) activates the timer (15) and simultaneously causes the CRT controller (6) to display the original display data stored in the save memory (10). To instruct. That is, the pointing cursor (21-A) is erased on the CRT (7) screen.

Further, FIG. 2B shows that character input is continued from the keyboard (3) while the pointing cursor (21) is erased, and the character input position management memory (12) is displayed. The content is further updated from the content at the time of FIG. 2A. Thus, while the pointing cursor (21) is being erased, the input control circuit (5)
Prohibits the position comparison operation by the position comparison circuit (14).

When the timer (15) finishes counting a predetermined time and outputs a time-up signal to the input control circuit (5), the input control circuit (5) causes the cursor position register (1
The contents of 3) are read out, the position information is transmitted to the CRT controller (6), and the pointing cursor (21-
B) is displayed and the position comparison circuit (14) was stopped.
To operate again. FIG. 2C shows a state in which the pointing cursor (21-B) is redisplayed at the position before being erased after the counting is completed.

Here, after the timer (15) finishes counting the predetermined time, the position comparison circuit (14) causes the pointing cursor (21-A) and the character cursor (20-A).
When the position coincidence signal is output to the input control circuit (5), the input control circuit (5) reactivates the timer (15) and at the same time the pointing operation is performed. The cursor (21) is again in the erased state.

When the mouse (4) is operated while the pointing cursor (21) is erased, the input control circuit (5) first stops the counting of the timer (15). , The position comparison circuit (14) is operated again, and then the CRT controller (6) is instructed to display the pointing cursor (21) at a new position. At this time, the contents of the cursor position register (13) are also updated.

[0025]

As is apparent from the above description, according to the present invention, the pointing cursor and the character cursor overlap each other when a character is input in a display device in which two cursors, that is, a character cursor and a pointing cursor are mixed. In this case, since the pointing cursor is erased, it is not necessary to move the pointing cursor so that the characters can be easily input, and the operability can be improved.
