Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] The present invention relates to an improvement in a pixel input method for a display device that creates an image by selecting and inputting pixels.

[Prior Art] The first pixel input method for a conventional display device
This will be explained using figures. In the figure, 1 is the front screen of the display device, 2 is the area that displays the screen being created, 3 is the pixel selection area that displays available pixels, 4 is the cursor that indicates the input position of the pixel,
5 is a selection key for selecting one pixel in the pixel selection area 3; 6 is a cursor movement key for moving the cursor 4; and 7 is a character input keyboard used for inputting characters.

Next, the operating procedure of the conventional example will be explained. Using the cursor movement key 6, move the cursor 4 to the position where you want to input a pixel on the display area 2.
Then, the pixel "□" to be input is selected by pressing "F1" of the selection key 5, and the pixel "□" is input to the position specified by the cursor 4 on the display area 2. By repeating this action,
Create an arbitrary screen on display area 2.

[Problems to be Solved by the Invention] Since the pixel input method of the conventional display device is configured as described above, the types of pixels that can be selected are determined by the number of selection keys 5 and the pixel selection area 3.
The disadvantage was that it was limited by the size of the

Furthermore, in order to increase the number of pixel types using the conventional method, it was necessary to adopt a multi-screen method in which pixels that cannot be displayed on one screen are displayed in the pixel selection area of the next screen. . For this reason, when the pixels required to create a screen span multiple screens, there are disadvantages such as the inconvenience of having to switch screens each time and the troublesome display of unnecessary pixels.

This invention was made to eliminate the above-mentioned drawbacks of the conventional example, and provides a display that increases the number of pixels that can be selected without switching the screen and eliminates the troublesome display of unnecessary pixels. The purpose is to provide a pixel input method for the device.

[Means for Solving the Problems] A pixel input method for a display device according to the present invention divides the display screen of the display device into a pixel selection area and a pixel display area having an area several times the area of the pixel selection area. , a first step of setting the pixel selection mode, a second step of displaying a plurality of pixels that can be selected in the pixel display area, and selecting pixels necessary for screen creation from among the plurality of pixels displayed in the pixel display area. a third step of selecting by moving a cursor; a fourth step of displaying and registering the pixels selected in the third step in the pixel selection area; and repeating the third and fourth steps. A fifth step of displaying and registering a limited number of pixels necessary for screen creation in the pixel selection area. After completing the first to fifth steps, the pixel display area is used as a display screen for screen creation, and the screen creation mode is entered. A sixth step for switching is provided.

[Operation] The pixel display area on the display screen is divided so that it has an area several to ten times as large as the pixel selection area. Therefore, compared to the conventional example in which pixels could only be displayed in the pixel selection area, a large number of pixels can be displayed in the pixel display area at once.

By selecting and registering only the pixels necessary for screen creation, pixels unnecessary for screen creation are deleted from the screen, and only the necessary limited number of pixels are displayed on one screen within the pixel selection area.

A pixel selection declaration key 14 is used when one wants to select one of the pixels displayed within the pixel. Reference numeral 14 indicates a character symbol corresponding to each pixel.

Note that the second pixel display area 2 in FIG.
The pixel display area 8 in the figure is used by switching the same part on the display screen 1 of the display device between the screen creation mode and the pixel selection mode by operating the screen creation mode key 9 and the pixel selection mode key 10. . Also, pixel display area 8
is several times larger than pixel selection area 3 (approximately 7 on the drawing)
The area is divided into two parts.

Generally, when creating a screen using a display device, it is extremely rare to use all or most of the available pixels, and in the majority of cases, several types of pixels are used repeatedly, as in the case of creating a flowchart. It is known to occupy Therefore, we will show a procedure for selecting and inputting only several types of pixels necessary for screen creation from among a large number of pixels.
