Abstract

PURPOSE:To improve the operability of a data processor by having a direct input of the data stored in a storage means according to the position set on a display means. CONSTITUTION:This data processor consists of a pointing device 1, a pointer 2, a VRAM 3, a display device 4, a ROM 5, a CPU 6, a RAM 7 containing a command table pointer 11, a command table 9, etc. When an access is given to the table 9, the position indicated by a pointing device 1 is stored in the pointer 2. This data is multiplied by 1/16 and stored in a command pointer 11. Based on the data on the pointer 11, an access is given to the table 9 and the processing is carried out in response to the obtained number. Here the display pattern of the display device 4 is stored in the VRAM 3 and the arrangement, sizes and forms of menus are intentionally changed to improve the operability of a data processor.

Description

Detailed Description of the Invention [Industrial Application Field] The present invention provides an input method for inputting the specified data by specifying one of several pieces of data displayed on the display screen of a display device. The present invention relates to a data processing device capable of performing the following steps.

[Prior Art] - Conventionally, in this type of data processing device, data that is to be displayed on the display screen of a display device (one of the pieces of data is converted into data specified on the screen with a light pen, a mouse and a cursor, etc.) To enter the corresponding data, first mark the position on the display screen indicated by the light pen or mouse and cursor.

The system detects the y-coordinate, etc., calculates which data area the obtained XIY coordinates are in, and then inputs the data corresponding to the designated position.

[Problem that the invention seeks to solve]

However, in this conventional technology, the data displayed on the display screen is Multiple areas for entering
Like the circuit board openings, each area is regular and has a small number of types and shapes. There is a problem in that it takes time to determine which data input area is located at the designated position on the screen.

[Means for solving problems]

A display means for displaying a plurality of data to be input, an instruction means for instructing a display position of one of the data displayed on the display means, and a memory storing data corresponding to the display position displayed on the display means. and a control means for reading data corresponding to the position indicated by the instruction means from the storage means.

[Effect]

Data stored in the storage means can be directly entered according to the position on the display means.

〔Example〕

Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.

FIG. 1 is a block diagram showing the configuration of a data processing device that is an embodiment of the present invention.

1 is a pointing device, for example, a mouse, a digitizer, a light pen, etc.

2 is a pointer, pointing device 1 is display device 4
Coordinate data corresponding to the point indicated by the upper cursor or the point indicated by the light pen on the display screen of the display device 4 is stored.

3 is a VRAM that stores display patterns to be displayed on the display 4;

4 is a display device that displays the display pattern in the VRAMd.

5 is a ROM which stores control programs and the like.

A CPU 6 controls other devices via a path line 10.

7 is a RAM, which is used for storing data input from the keyboard 8 and for other calculations and processing. It also has a command table pointer 11 for accessing the command table.

Reference numeral 9 denotes a command table in which coordinates and commands as described later are stored in correspondence.

10 is a pass line.

FIG. 2 shows the correspondence between the contents of the VRAM 3 and the contents of the command table 9. Here, the contents of the VRAM 3 are the same as those displayed on the display 4.

Here, the display device 4 has a pixel count of 640 x 480 dots.

The command table 9 corresponding to this has a structure of 16×16 dots, which can be the minimum block unit of commands. In other words, the minimum block unit of the command is 40x30
They are lined up.

If this minimum block unit is 1 x 1 dot, the commands on the menu screen can be made into any pattern, but then the command table 9 has the same number of pixels as the menu screen.
Since this command data is required, the capacity of the menu screen increases depending on the type of command, which is not practical.On the other hand, if the block unit is set to 40 x 40, the minimum block unit for commands is 16 horizontally x 12 vertically. , it becomes impossible to create a menu with an arbitrary pattern. The block unit of 16 x 16 dots shown in Figure 2 has a total of 40 x 3 commands, assuming that the maximum number of commands it can hold is 256 = 2'.
0X8 = 9600 bits = 640X of the entire menu screen
The memory capacity is only 1/32 of 480=307200 bits, and the shape and arrangement of menus that can be created can be arbitrarily approximated, which is realistic. This command table stores the number of the command to be executed for each block.

This command table 9 can be set from the keyboard 8. Now, there are 40x30 command tables 9, so (x, y) (1≦X≦40.1≦y≦30
) and the command to be stored at that position are set from the keyboard 8.

In addition, the contents of VRAM3 can be stored in the image reader or keyboard 8.
It can be created using the drawing function.

The contents of VRAM 3 according to the present invention are shown in FIG.

Figure 3 includes all the functions of Figure 5, but is a case in which the layout, size, and shape of the menus are intentionally changed.

This is just an example and is not a realistic example, but when considering operability and visibility, the eye structure shown in Figure 5 has its limitations, and the method of the present invention does not allow comments,
It is clear that the ability to add focus has also been improved.

Next, the case of accessing this command table 9 will be explained with reference to the flowchart of FIG.

First, in step S1, the position indicated by the pointing device 1 is stored in the pointer 2 in units of pixels, and in step S2, the data of the pointer 2 is
/16 L, is stored in the command pointer 11, and based on the data of this command pointer 11, the command table 9 is accessed in step S3, and the process corresponding to the number obtained here is executed.

The minimum block of commands is 16X on the display dot.
The choice of 16 dots is related to the number of dots required when displaying a kanji font, but it is realistic to use a larger or smaller number such as 20x20 or 24x24. The types of commands can also be increased or decreased depending on the type of VRAM. The VRAM is also not fixed to 640 x 480 dots, and this size can also be arbitrarily set depending on the system. In any case, the present invention can be realized by having a command table compatible with VRAM.

Also, although we have explained that data input is a command, it is also possible to input character data corresponding to -ゞ-ゞ in the command table.As explained above,
The quality of operability is considered to be an important point in image editing machines, etc., and menu selection in particular is a task that is frequently performed. The effect is large. .
