Description

TECHNICAL FIELD The present invention relates to a cursor control device, and more particularly to a cursor control device for controlling a cursor for recognizing an input position on a CRT (cathode ray tube) display device having a graphic function.

The relationship between dots (pixels) and text (character) areas of a conventional CRT device equipped with a high-resolution graphic function is as shown in FIG. Each text displayed on a CRT includes 2-byte text as shown in figure (b), and figure (
As shown in Figure C, there is 1-byte text that is created by dividing the 2-byte text into two by a vertical dividing line, and generally text (characters) is expressed by a collection of dots (Figure (d) )reference).

The text display area is 16 vertically for 2-byte text.
The dot occupies 16 horizontal dots (this is expressed as 16×16). When this text is displayed on the screen, the text position is expressed numerically within a range of 25 lines in the vertical direction and 40 columns in the horizontal direction (25 lines x 40 columns) as shown in the example in FIG.

In the case of 1-byte text, the text display area is 16 x 8 dots, and the text position is expressed within a range of 25 lines x 80 columns. Furthermore, when 1-byte text and 2-byte text coexist, it is generally expressed using 25 lines x 80 columns of text positions.

On the other hand, the dot position on the 087 screen is expressed numerically within the range <400 x 640, as in the example shown in Figure (a). In the following description, these positions will be expressed as (vertical numerical value, horizontal numerical value). In this example, the 2-byte text occupies a 16 x 16 dot area, but the 2-byte text
Of course, it may be 4×24 dots or may occupy many dots.

Now, in recent text input devices such as Japanese word processors, character data on the 087 screen is moved after positioning by moving the character position recognition cursor, but this also applies to graph creation input. In addition to recognizing the position using a special pixel position recognition cursor, it is also possible to directly indicate the pixel position numerically.
゛However, for pixel position recognition, for example (0
It takes a considerable amount of time to move the cursor from point , 0) to point (0,539), and it is troublesome to directly indicate the pixel position with numerical values.

Purpose of the Invention The present invention facilitates and reliably recognizes pixel positions by moving a pixel position recognition cursor and a character position recognition cursor independently of each other, and by interlocking the pixel position recognition cursor with the character position recognition cursor. The purpose is to provide an executable cursor control device.

Structure of the Invention A cursor control device according to the present invention includes a character position recognition cursor (a character cursor, referred to as a C cursor) and a pixel position recognition cursor (a dot cursor, referred to as a C cursor).
A cursor (referred to as a cursor) is provided, and the two can be moved and position recognized independently of each other, and the D cursor can be moved freely within a text area recognized by the C cursor. In other words, mode indicating means indicates each state of the independent movement mode of the C and D cursors and the linked movement mode of both cursors, direction indicating means indicates each direction of movement of both cursors, and mode indicating means Means for storing each individual movement mode state of the cursor and independently controlling the movement of the corresponding cursor in the direction of movement indicated by the direction indicating means, and storing the state of the bi-force-nor interlocking movement mode by the mode indicating means. The configuration further includes means for controlling the movement of the D cursor within the recognition area of the C cursor when a D cursor independent movement mode is instructed by the mode instruction means in this mode.

The information held in C3M60 is displayed in the text area of CBr4 located by the numerical value of CKS53. Next, the means 35 operates to perform the action (2) described above. At this time, since CJ 54 or CK 55 is increased or decreased by +1 by the movement key, it has the effect shown in FIG. 4(b). Next, the means 36 operates to perform the above-mentioned action. With the above configuration, the C cursor can be moved up, down, left, and right on the screen in response to a movement instruction from the means 11.

Note that the C cursor position display means 37 is a means that operates after the means 36, and displays the CJS4 and C cursor in an appropriate area of the CRT9.
It functions to display the numerical value indicated by KS5.

Next, a series of operations and effects of the D cursor will be explained in detail. When the D key is input from the means 10, the means 31 refers to the MOD51, and if it is in the state of tt Ctt, the means invites to set ``D'' in the MOD51. If so, the contents of MOD51 will not be changed.

Next, the C cursor erasing means 4o operates to display the information held in C3M6o at the screen text position of CBr4 indicated by the numerical values held in CJ 54 and CJ 55 (referred to as action θ). This action erases the C cursor displayed on the screen. Next, the screen information holding means 45 operates to store pixel information (i.e., dot presence/absence) of the text position of CBr4 located at DJ (b) and DK (numerical value 55 (normally the first value is °'0')). Information, color information.

a) IJ butte information, etc.) is taken in and held in the D information holding memory 70 (referred to as DSM) (referred to as action O).

Next, the D cursor display means 46 operates to take in the previously held D cursor pixel information 71 (referred to as DKM) and display it at the pixel position of CBr4 positioned by the numerical values of DJ64 and DK55. (referred to as action). FIG. 5(a) shows an example of the result of this action.

Next, when the movement key is input by the means 11, the means 31 refers to the fact that the MOD 51 is D'' and operates the D cursor position changing means.

Thereafter, the same operations as those for moving the C cursor described above are performed one after another, and D J 64. The numerical value of DK65 is held in the D cursor horizontal position holding memory 62 (referred to as DJS) and the c cursor vertical position holding memory 63 (referred to as DKS), and addition and subtraction are performed by the means 43 in response to the movement keys to compare the ranges. D
The updated values are set in J64, D, and J65. Next, the screen information recovery means 44 operates, and further the means 45 and 46 operate (referred to as action G).
