DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method and an apparatus for creating screen information to be output and displayed on a display device in an information processing device or various control devices.
In particular, display screens in which multiple screen display components such as lists and buttons, which are the units of display information, are arranged, should be properly redesigned when changing the screen resolution or increasing or decreasing the screen display components, taking into account the display space. It is possible to configure.

[0002]

2. Description of the Related Art Generally, in an information processing apparatus, when processing is performed interactively using a screen of a display device, data such as a list and a plurality of information of different types such as buttons for inputting operation commands are displayed on a single screen. Often placed and displayed within. (A) of FIG.
In the example, a display screen area is set in a display frame of a display device (indicated by a frame), and a plurality of information units are indicated by rectangular or circular blocks in the area. In addition,
Here, the information of each unit displayed on the screen is generalized and referred to as a screen display component.

In screen design, the layout of each screen display component displayed on the screen on the screen, that is, the vertical and horizontal sizes and display positions of the display components are set in the form of a screen definition body. By the way, since the size and display position of such a screen display component are determined based on the pixel address, when the resolution of the display is changed with the same screen size,
Since the number of pixels per unit area is increased or decreased, the size of the screen display component and the interval between the screen display components are reduced or enlarged as the resolution increases or decreases.

Therefore, when a screen display component designed at the original resolution is displayed as it is on a screen of a new resolution,
When the resolution is increased, the display screen is reduced and displayed in the display frame as illustrated in FIG. 10B, and when a large empty space is created or the resolution is decreased. As shown in FIG. 10C, the display screen is enlarged and displayed, and a part of the display component enlarged and displayed at the same ratio may protrude from the right side and the lower side. In such a case, conventionally, the resolution is increased or reduced, and the entire display screen is scaled up or down in reverse according to the reduced ratio, and the individual screen display components are scaled at an appropriate ratio. The screen was reconfigured so that the proper arrangement of the screen display components could be obtained.

[0005] Even when the screen size is changed in accordance with the change in resolution and the number of pixels per unit area does not change, the entire screen is enlarged or reduced by following the expansion and contraction of the screen size, and the original display balance is maintained. The screen was reconfigured to keep it.

Conventionally, in such a case, a scaling process of manually correcting a screen definition body for each screen display component, or uniformly enlarging or reducing the entire screen using a software function has been performed. However, the method of performing the correction manually increases the burden on the user, and the method of uniformly performing the scaling process using the software function deteriorates the screen efficiency depending on the type of the screen display component,
There were problems such as inconvenience in cursor operation.

Reference numeral 8 denotes a screen design unit. When the screen characteristic analysis unit 7 detects that there is a change, the screen display component setting information 5
The screen layout of each screen display component is redesigned according to the change attribute of the display condition set in. The design result is reflected in the screen display component setting information 5.

Reference numeral 9 denotes a screen drawing unit, which draws and outputs each screen display component of the screen design result on the display screen 3 of the display device 2.

[0015]

In FIG. 1, the display device 2 has a unique resolution and screen size determined by the type, and when connected to the information processing device 1, the type information is notified to the information processing device 1, and the information processing device 1 The screen characteristic information 4 such as the resolution and the screen size corresponding to the type is set in the field.

Screen display component setting information 5 including a plurality of screen display components to be output and displayed on the display screen 3 of the display device 2, display area sizes, addresses, and display condition change attributes is created and set. When there is an increase / decrease (addition / deletion) or change in the screen display component, the corresponding screen display component setting information is added, deleted, or changed. The display condition change attribute is set with information such as the size of the merit obtained by changing the size of the screen display component, restrictions on how to change the size, or component type information that defines such information.

The display screen creation unit 6 is started automatically by a command instruction or at system startup.
When the display screen creating unit 6 is activated, the screen characteristic analyzing unit 7 first functions to check whether any of the screen characteristic information 4 and the screen display component setting information 5 has been changed.
When a change is detected, for example, a change in resolution is detected, the screen design unit 8 is made to function.

The screen design unit 8 performs screen design in accordance with whether the resolution has been changed, whether the number of screen display components has been increased or decreased, and how the display condition change attribute of each screen display component has been changed. Redo. At this time, for example, if the resolution is increased, the screen space is substantially enlarged, and the apparent size of the screen display component is reduced. Therefore, basically, the size of each screen display component is increased. In accordance with the change attributes set for the individual screen display components, for example, an enlargement process is performed by giving priority to a component having a large merit for change and taking into account any restrictions on the vertical and horizontal enlargement ratios. Also, if there is an increase or decrease in the number of screen display components, the size of each screen display component is reduced in consideration of the change attribute of each screen display component so that all screen display components are arranged in an appropriate size and layout within the screen display space. Perform processing or enlargement processing.

As described above, the screen design is performed in consideration of the change attribute of each screen display component. For example, in the case of data such as a list, a direction in which the amount of displayed data is as large as possible (or a direction in which the data amount is not reduced). In addition, with the buttons, the screen can be reconfigured with a shape, size, and position convenient for the cursor operation.

[0020]

FIG. 2 shows a basic processing flow when the resolution of the display device is changed in one embodiment of the screen designing unit 8 shown in FIG. The processing content will be described according to the flow.

First, the vertical / horizontal ratio of each screen display component in the original screen is calculated. Next, a standard value HYOJUN of an enlargement ratio (when the resolution increases) or a reduction ratio (when the resolution decreases) corresponding to the change in resolution is set. The enlargement / reduction ratio based on the standard value is for returning the apparent size of the screen display component changed by the change of the resolution to the original size.

When enlargement processing is performed due to an increase in resolution, the change attribute set for each screen display component is checked, and enlargement is made larger than the standard value of the enlargement ratio (based on the apparent size. Only screen display parts that have the advantage of being larger than the size of
The set is defined as Lgrp, and the enlargement ratio HYOJUN + α (α> 0) is slightly larger than the standard value for each part of Lgrp.
give. The value of α is appropriately set in advance.

On the other hand, in the case where the resolution is reduced and the reduction process is performed, it is necessary to reduce the reduction ratio from the standard value of the reduction ratio based on the change attribute of each screen display component (to reduce the apparent size to the original size). ), And only the parts that have the advantage of
A reduction ratio HYOJUN-α (α> 0) slightly smaller than the standard value is given to each of the parts p.

In this manner, after determining the enlargement ratio or the reduction ratio for the screen display component which is particularly desired to be enlarged or reduced, the remaining display space is allocated to other components, and the enlargement ratio or the reduction ratio of those components is determined. Are calculated in reverse, and the respective enlargement ratio and reduction ratio are determined. The layout of each part as a result of scaling up or down for each part is reflected in the screen display part setting information,
It is passed to the screen drawing unit 9.

FIG. 3 is a flowchart of a process for determining the horizontal size of the button and the distance between the buttons in consideration of the length and margin of a character string displayed in the button when the screen display component is a button. FIG. 4A shows a specific example of the button. Hereinafter, the processing content will be described with reference to a flow.

First, the sum SU of the character string lengths of the button names of the buttons, such as the button name “function 1” in the example of FIG.
M The STR is calculated, and then the minimum value, the intermediate value, and the maximum value of the button both end margins, which are the sum of the left and right margins provided at both ends of the button name, are determined. For example, the minimum value is set to "0" and the maximum value is set to twice the character width.

Next, the distance L between the buttons Set the maximum value of MAX. Next, the margins at both ends within each button (FIG. 4)
When the value of (a) is set to the maximum value, it is checked whether a part of the button is out of the display area and chipped. If the button is not missing, the margins at both ends are set to the maximum value. Changes the margins to the middle value and the minimum value in order, and checks whether the button is missing in each case.If the button is not missing at the middle value, sets the both margins to the middle value. If the value is not missing, set the margins at both ends to the minimum value.

In this way, the character string length for each button
Determine the horizontal size of the button from the sum of

FIG. 6 is a detailed flow of the processing for judging whether or not a button is missing when the margins at both ends of the button are set to intermediate values in the flow of FIG. First, the displayable horizontal value of the button display area is displayed. X
For the N buttons to be arranged, a horizontal value obtained by adding a margin to each of the buttons from button 1 to button N is a button1. X to buttonN X is button1 X to buttonN Find the sum of X, yoko Let it be X.

Here, yoko X value and display
By comparing with the value of X, yoko X ≦ display
If it is X, it is determined that there is no missing button, and yok
o X> display If X, button is missing
It is determined that.

The number of buttons and the length of the button character string have respective upper limits, and an error is issued if the number of buttons or the number of characters is set beyond that. As for the method of setting the change attribute of the screen display component, the size of the advantage of enlargement / reduction is set for each type of display component, but the advantage of enlargement / reduction in the vertical direction and the advantage of enlargement / reduction in the horizontal direction are set.
The reduction merit and the reduction merit can be set separately. For example, when the display component is a list box, the enlargement in the vertical direction leads to an increase in the number of display data, so the enlargement advantage is large, but the enlargement advantage in the horizontal direction is small. Also, when the display component is a button, the number of characters to be displayed is originally small, so there is not much benefit in expanding in the vertical direction and it is normal, but in the horizontal direction, if the button can be extended horizontally, the pointing operation with the mouse cursor Since the moving distance can be shortened, the merit of expansion is great. In this way, the merits and demerits of vertical / horizontal enlargement / reduction are ranked in advance according to the type of display component, and when redesigning the screen by increasing or decreasing the resolution or increasing or decreasing the display component, It is possible to preferentially enlarge / reduce a display component having a large merit of enlargement / reduction.

7 to 9 show specific examples of the screen design change. FIG. 7 shows an example of a screen design change when the number of pixels per unit area is changed. A, B, C, D in the figure
Are display components, and the enlargement / reduction merit set in each change attribute is as shown in FIG. 7D.

FIG. 7A shows a screen designed at the original resolution. FIG. 7B is a screen automatically redesigned by applying the same enlargement ratio to each display component by the conventional method. On the other hand, FIG. 7C shows a screen redesigned by adjusting the enlargement ratio in consideration of the change attribute of each display component according to the present invention. In FIG. 7C, the vertical size is not expanded because the display component A has a small enlargement advantage. Instead, the vertical size of the display component C having a large enlargement advantage is enlarged, and the display data options are reduced from five. It has been increased to seven. As a result, the number of times of scrolling when referring to options can be reduced as compared with the related art.

FIG. 8 shows an example of a screen design change when a part of the display component is deleted. FIG. 8A shows the original screen, in which the display components A3 to A5 are deleted. FIG. 8B is a screen automatically redesigned by the method of the related art, and the area where the display components A3 to A5 are present is blank. FIG. 8C shows a screen redesigned according to the present invention. By giving the display components A1 to A5 a change attribute that the merit of enlargement in the horizontal direction is large, a blank area is effective as shown in FIG. The display components A1 and A2 are stretched in the horizontal direction by using them to enlarge the area. Thereby, in the case of the buttons of the display components A1 and A2, pointing with the cursor becomes easy.

FIG. 9 shows an example of a screen design change when a display component is added. FIG. 9A shows the original screen, in which a display component A5 is added. FIG. 9B is a screen automatically redesigned by the method of the conventional example, and the added display parts A5 are the display parts A1 to A in FIG.
Since 4 is displayed in a small empty space at the right end of the upper area where 4 is displayed, the display component A5 is displayed in a chipped manner. FIG. 9C shows a screen redesigned according to the present invention. By setting in advance the reduction attribute in the horizontal direction to the change attribute of the display components A1 to A5, each of the display components A1 to A5 is displayed.
A5 can be reduced in the horizontal direction and properly arranged on the screen.

[0038]

According to the present invention, by setting a change attribute for each display component in advance, it is possible to recognize a display component which is preferably enlarged or reduced when changing or increasing or decreasing the resolution or the display component. In this way, the screen can be appropriately enlarged or reduced, and the entire screen can be automatically reconfigured with no waste and an efficient and easy-to-use screen, thereby reducing the screen design load and improving the MMI.
