[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a cursor display control device.

[0002]

2. Description of the Related Art In a personal computer, an image processing apparatus, etc., a position on the screen and processing contents are designated by using a mouse cursor which moves on the screen in response to a mouse operation.

[0003]

The mouse cursor is displayed as an icon such as an arrow "↑" or a cross "+". However, since the size of the displayed icon is small, the operator may have to move the mouse during screen work. Often you lose sight of the cursor. In particular, if the work area where the mouse cursor can move is many times larger than the display area of the screen, the mouse cursor may exist outside the screen. In such a case, the operator operates the mouse in various directions to search for the mouse cursor, which is very troublesome. The subject of this invention is
This is to allow the operator to easily know the position of the other cursor (eg, mouse cursor) by looking at the display character of one cursor (eg, text cursor) displayed on the screen.

[0004]

Means for Solving the Problems The means of the first invention is as follows. The display means displays a first cursor (one cursor, for example, a text cursor, a mouse cursor, etc.) and a second cursor (the other cursor, for example, a mouse cursor, a text cursor, etc.).
The first cursor storage means stores the position of the first cursor on the display means. The first cursor changing means is composed of, for example, a keyboard having a cursor moving key, a mouse, etc., and changes the position of the first cursor. The second cursor storage means stores the position of the second cursor on the display means. The second cursor changing means is composed of, for example, a mouse, a keyboard having cursor movement keys, or the like, and changes the position of the second cursor. The cursor position detecting means detects the position of the second cursor viewed from the first cursor based on the position of the first cursor and the position of the second cursor. The cursor display control means determines a display character indicating the direction in which the second cursor is present based on the detection result of the cursor position detection means, and causes the determined display character to display the first cursor. The means of the second invention is as follows. The display means displays a text cursor and a mouse cursor. The text cursor storage means stores the position of the text cursor on the display means. The key input means is composed of, for example, a cursor movement key, and changes the position of the text cursor. The mouse cursor storage means stores the position of the mouse cursor on the display means. The mouse changes the position of the mouse cursor. Mouse cursor position detection means
The position of the mouse cursor seen from the text cursor is detected based on the position of the text cursor and the position of the mouse cursor. The text cursor display control means determines a display character indicating the direction in which the mouse cursor exists based on the detection result of the mouse cursor position detection means, and displays the text cursor with the determined display character.

[0005]

The operation of the means of the first invention is as follows. When the position of the first cursor is changed in response to the operation of the first cursor changing means, or when the position of the second cursor is changed in response to the operation of the second cursor changing means, the cursor position detecting means is set to the first position. The position of the second cursor viewed from the first cursor is detected based on the position of the first cursor and the position of the second cursor. Based on the detection result, the cursor display control means determines the display character indicating the direction in which the second cursor exists, and causes the determined display character to display the first cursor. The operation of the means of the second invention is as follows. When the position of the text cursor is changed according to the operation of the key input means, or when the position of the mouse cursor is changed according to the operation of the mouse, the mouse cursor position detection means moves the position of the text cursor and that of the mouse cursor. The position of the mouse cursor seen from the text cursor is detected based on the position. Based on the detection result, the text cursor display control means determines the display character indicating the direction in which the mouse cursor exists, and displays the text cursor by the determined display character. Therefore, the operator can easily know the position of the other cursor (for example, the mouse cursor) by looking at the display character of the one cursor (for example, the text cursor) displayed on the screen.

The window position memory 6b is a memory for storing coordinate data indicating the position of the window displayed on the screen of the display device 9. When displaying a plurality of windows on the screen, coordinate data corresponding to each window is stored. The text cursor position memory 6c stores coordinate data indicating the position of the text cursor on the screen. This coordinate data is sequentially changed according to the operation of the cursor movement key on the keyboard 1. Mouse cursor position memory 6
d stores coordinate data indicating the position of the mouse cursor on the screen. This coordinate data is sequentially changed according to the operation of the mouse 4.

The display memory 7 stores display data displayed on the display device 9, and the stored contents are sequentially rewritten according to the contents of the window position memory 6b, the text cursor position memory 6c, and the mouse cursor position memory 6d. Be done. The display data stored in the display memory 7 is displayed on the display device 9 under the control of the display control unit 8. The display device 9 is composed of, for example, a CRT display device.

Text cursor display character ROM 1
As shown in FIG. 2, 0 stores 16 display characters C01 to C16 in advance. This display character is displayed when the mouse cursor is on the screen or in the work area (edit area), and the arrow is placed in the square frame, and the direction of the arrow is as seen from the text cursor. It shows the direction in which the mouse cursor is.

Next, the operation of the above embodiment will be described with reference to FIGS. 3 and 4. FIG. 3 is a diagram showing each coordinate on the screen. Now, as shown in FIG. 3 (D), on the screen of the display device 9, an active window (meaning the currently designated window when a plurality of windows are displayed) AW, a text cursor TK, and a mouse. It is assumed that the cursor MK is displayed. In this embodiment, each time the text cursor TK or the mouse cursor MK moves, the position of the text cursor TK and the position of the mouse cursor MK are compared, and the display character of the text cursor TK is changed. That is, when the cursor movement key of the keyboard 1 is operated to move the text cursor TK or the mouse 4 is operated to move the mouse cursor TK, the CPU 3 detects an interrupt due to the cursor movement, and the processing of FIG. 4 is started. To be done. When the mouse cursor MK does not exist on the screen or in the work area, the text cursor TK is displayed as a normal display character, for example, one character in full blink or underline blink.

FIG. 4 is a flow chart showing the processing for determining the display character of the text cursor TK according to the movement of the cursor. First, in step S1,
Coordinates of the text cursor TK on the window AW
