Abstract

PROBLEM TO BE SOLVED: To provide a display system capable of displaying a created object for display according to its original design on a display of any resolution. SOLUTION: When displaying a display object on a display, a resolution discrimination part 13 firstly discriminates the resolution of the display for displaying the object. Following it, a resolution ratio calculation part 14 calculates a ratio of the resolution of a display assumed to be used at the time of designing the display object to that of the discriminated display. Next, using this resolution ratio, a display object value calculation part 15 calculates display object values such as a display position and the number of display pixels. A display control part 16 extracts necessary data from a storage means 4, and performs shifting, variation in power, or the like by using the display object values, and then displays the display object on the display.

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a display capable of displaying a designed object in a screen state as intended by a designer even when the designed object is displayed on a display having a resolution different from an assumed display. About the system.

[0002]

2. Description of the Related Art Conventionally, various displays for computers have been put on the market. The resolution of the display varies depending on the model, and the choice is left to the user. Therefore, when displaying the same image on displays with different resolutions, the position and size of the display area relative to the entire screen size will be different. Specifically, on a display with a low resolution, an image is displayed relatively large with respect to the entire screen size, and on a display with a high resolution, the image is displayed relatively small with respect to the entire screen size.

[0003]

In the above conventional method,
In order to design a display object assuming a display of a certain resolution, if the display object is displayed on a display having a resolution different from the assumed display, the layout relative to the entire screen size must be adjusted. It will be different. In particular, when the resolution of the display to be displayed is lower than the assumed resolution, a part of the display object may be partially displayed. For example, a case will be described in which a display object is designed such that horizontal × vertical pixels are displayed on the entire screen of a display having a resolution of x1 × y1. FIG. 3A shows an example of such a display object. In the display object shown in FIG. 3A, the image object A, the character object B, and the operation button object C are arranged by the designer in a well-balanced manner while being aware of the screen size. The background object H is designed to have the same size as the screen size. When such a display object is displayed on a display having a resolution of x2 × y2 pixels (x2 ≧ x1, y2 ≧ y1), a display as shown in FIG. 3B is obtained, and the state of the screen intended by the designer is displayed. It turns out that they are completely different. Usually, in order to cope with this phenomenon, it is necessary to design a display object for each different resolution, and the work load increases accordingly.

Accordingly, an object of the present invention is to provide a display system capable of displaying a created display object on a display of any resolution as designed.

[0005]

According to the first aspect of the present invention, a display resolution is identified, and a resolution ratio between the identified resolution and a preset assumed resolution is calculated. Using the calculated resolution ratio, the display position of the display object to be displayed on the display, the display target value such as the number of display pixels is calculated, and the display object is displayed on the display using the display target value. It is characterized in that it is displayed.
According to the first aspect of the present invention, the resolution of the display to be used is identified, the ratio between the resolution and the resolution assumed at the time of designing the display object is calculated, and scaling, movement, etc. are performed using the ratio. Since the display object is displayed on the display, the display can be performed on the entire screen at the same ratio as that originally designed, regardless of the resolution of the display.

According to a second aspect of the present invention, there is provided an image object as one of the display objects according to the first aspect of the present invention, wherein the image object is obtained by converting image data prepared in advance into the calculated resolution. It is characterized by being created by scaling the number of display pixels calculated based on the ratio. According to the second aspect of the present invention, the image object is created by scaling the prepared image data using the resolution ratio of the display used and the display assumed at the time of design. By preparing only one, it is possible to support displays of different resolutions.

According to a third aspect of the present invention, an image object is provided as one of the display objects according to the first aspect of the present invention, and the image object is a plurality of image data of a plurality of image data having different resolutions prepared in advance. Of which
The number of pixels closest to the number of display pixels calculated based on the calculated resolution ratio is selected and obtained. According to the third aspect of the present invention, image data having the number of pixels closest to the number of display pixels calculated based on the resolution ratio of the display to be used and the display assumed at the time of design is converted into a plurality of image data having different resolutions prepared in advance. Since the image data is extracted from the image data, it is possible to reduce the time required for the scaling process of the image data.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Preferred embodiments of the present invention will be described below in detail with reference to the drawings. FIG. 1 is a diagram showing an example of a configuration of a display system according to the present invention. In FIG. 1, 1 is a display, 2 is a computer, 3
Denotes a display program, and 4 denotes storage means. The display 1 is controlled by the display program 3 so that
It can display various information such as images, characters, figures, etc., and any resolution can be used. Computer 2
Various types including personal computers can be used. The computer 2 recognizes the resolution information of the display 1 at the time of starting and holds the information in a memory. The display program 3 plays a central role in the present invention, and functions as a display system when executed by the computer 2. This display program 3
Records information of display objects to be displayed on the display, and also records path names in the storage unit 4 of files of image data and character data used for display. The storage means 4 stores the display program 3
An image file recording image data displayed by
It stores a character file in which character data is recorded, and is realized by an external storage device such as a hard disk.

Next, regarding the processing operation of the present display system, a display object designed assuming a display having a resolution of x1 × y1 pixels as shown in FIG. The case of displaying will be described as an example. In the example shown in FIG. 3A, the image object A, the character object B, and the operation button object C are arranged on the background object H in a well-balanced manner as described above. The display object means a generic term for each of these objects. It is assumed that the display object shown in FIG. 3A is designed under the following (condition 1).

(Condition 1) Number of pixels of image object A: a1 × a2 pixels Number of pixels of character object B: b1 × b2 pixels Number of pixels of operation button object C: c1 × c2 pixels Number of pixels of background object H: x1 × y1 pixel Font size of character in character object B: d point Arrangement position coordinates of image object A: (e1, e2) Arrangement position coordinates of character object B: (f1, f2) Arrangement position coordinates of operation button object C: ( g1, g
2) Arrangement position coordinates of background object H: (0, 0)

In the above (condition 1), the location of each object may be based on any point in the object, but in this example, the upper left point of the object is determined as the location. The procedure for creating a display object as shown in FIG. 3A is written in the display program 3 and is generated by the display program 3 except for the content data of the image object and the character object. Further, the content data such as the image object and the character object are written in the display program 3 with the path name in which the content data is stored. Is displayed.

Next, a specific processing operation will be described with reference to a flowchart of FIG. First, display program 3
Is executed, the resolution of the display 1 held by the computer 2 is identified (step S1). Here, x2 × y2 pixels are identified. Next, the identified resolution of the display 1 is compared with the assumed resolution written in the display program 3, and the ratio is calculated (step S2). In this example, the ratio of the resolution of the display 1 to the assumed resolution is x2 / x1 in the horizontal direction and y2 / y1 in the vertical direction.

Using the ratio calculated in step S2 as a scaling factor, the number of pixels of each object in the display object and the value of the display position are scaled and calculated as display target values (step S3). X2 / x1 = x
When h and y2 / y1 = yh are replaced, the display target values are as follows.

(Display target value) The number of pixels of the image object A: (a1 × xh) × (a2
× yh) pixels The number of pixels of the character object B: (b1 × xh) × (b2
× yh) pixels The number of pixels of the operation button object C: (c1 × xh) ×
(C2 × yh) pixels The number of pixels of the background object H: (x1 × xh) × (y1
× yh) Pixel Font size of character in character object B: d × x
h point Arrangement position coordinates of the image object A: (e1 × xh, e
2 × yh) Arrangement coordinates of character object B: (f1 × xh, f
2 × yh) Arrangement coordinates of the operation button object C: (g1 × x)
h, g2 × yh) Arrangement coordinates of the background object H: (0, 0)

[0015] Among the display target values, character object B
The font size d of the characters in the parentheses is multiplied by the scaling factor xh, which is the case when xh ≦ yh. xh> y
In the case of h, the magnification yh is multiplied. In other words, the font size of the character is scaled smaller.
This is to prevent inconveniences such as characters being displayed overlapping each other when the magnification is changed to the larger one.

Subsequently, using the calculated display target value,
Each object is scaled and displayed on the display 1 (step S4). With respect to the image object A, image data is extracted according to the path name written in the display program 3, and the number of pixels of the image is (a1 × xh) × (a2
× yh) and the position coordinates (e1 × x
h, e2 × yh). When the number of pixels of an image increases, the value of a newly generated pixel is obtained by performing interpolation of peripheral pixel values. If the number of pixels in the image decreases, pixels are thinned out at a predetermined rate.
For the character object B, character data is extracted according to the path name written in the display program 3, the font size is changed to d × xh points, and displayed at the layout position coordinates (f1 × xh, f2 × yh). In the case of a character object, when the number of characters is small, character information can be directly written in the display program 3. With respect to the operation button object C and the background object H, the existence range of the object is determined according to the size and the arrangement position coordinates, and the color information of each object written in advance in the display program 3 is given to all the pixels inside the object. Is displayed. The state of the screen of the display 1 at this time is shown in FIG. As can be seen from comparison with FIG. 3A, by performing the processing in the present display system, it is possible to perform the display as designed even on the display 1 having a resolution different from the assumed resolution.

In the above example, the case where one display object is displayed in the display program 3 has been described. However, in a general application program, the entire display object is switched to display another display object. It is common to switch and display only one object. When the entire display object is switched, the processing as described above is performed for each display object.
If only one object, for example, only an image object, can be switched, the corresponding image data is read from the path name written in the display program 3 according to the switching instruction (eg, click of an operation button), and is displayed in a variable scale. .

Here, the configuration of the display program 3 will be described. FIG. 4 shows the display program 3 for each functional block. As shown in FIG. 4, the display program 3 is mainly composed of a display support unit 11 and a resolution support unit 12. The display corresponding section 11 is for acquiring information of the display 1 and for passing information to be displayed on the display, and has a resolution identifying section 13 and a display control section 16. The resolution correspondence unit 12 is for calculating information for converting the designed display object into a state corresponding to the resolution of the display, and has a resolution ratio calculation unit 14 and a display target value calculation unit 15.

The resolution discriminator 13, the resolution ratio calculator 14,
The display target value calculation unit 15 and the display control unit 16 respectively perform steps S1 to S in the flowchart of FIG.
4 is provided.

In the above example, only one image data is prepared, and the image object is created by changing the number of pixels of the image so as to have the calculated display target value. Since there is another method for creating, the method will be described. In another method, a plurality of image data having different resolutions are prepared in the storage unit 4. Then, image data having a resolution (ie, the number of pixels) closest to the calculated display target value is extracted, and is displayed on the display 1 as an image object. By doing so, there is an advantage that the image scaling processing is not required and the processing is performed quickly.

In the above example, the processing in a stand-alone computer has been basically described. However, the present invention can be applied to a network computer as shown in FIG. In FIG. 5, reference numeral 21 denotes a server computer, and reference numerals 22a to 22d denote client computers. Each of the client computers 22a to 22d has a display having a different resolution. The server computer 21 holds content data such as image data and character data.
The client computer 22 executes the display program 3
And character fonts. This display program 3 has the same functions as those shown in FIG. When the display program 3 is executed in the client computer 22 in such an environment, the processing of steps S1 to S3 shown in the flowchart of FIG. However, after the calculation of the display target value, data necessary for displaying image data, character data, and the like is obtained by accessing the server 21.

Here, the supply of various data in the display system shown in FIG. 1 will be described. This display system can be supplied on a storage medium such as a DVD or a CD-ROM. For example, the display program 3, image files, character files, and the like shown in FIG. 1 are recorded on a DVD. The user sets the DVD on the computer 2 to which the DVD reader is connected, and installs the program, whereby the display program 3 and the content data such as image files and character files are stored in the storage means 4 such as a hard disk. You. In this way,
A computer or the like functions as a display system. When the execution instruction is issued, the display program 3 is read into the computer 2 and a display process is performed.

[0023]

As described above, according to the present invention,
Identify the resolution of the display to be used, calculate the ratio between the resolution and the resolution assumed at the time of designing the display object, and perform scaling, movement, etc. using the ratio to display the display object on the display. Therefore, the display can be performed on the entire screen at the same ratio as that originally designed, regardless of the display of any resolution. In particular, when an image object is created by scaling the prepared image data using the resolution ratio of the display to be used and the display assumed at the time of design, one original image data is prepared. By simply placing them, it becomes possible to support displays with different resolutions. Further, image data having the number of pixels closest to the number of display pixels calculated based on the resolution ratio between the display used and the display assumed at the time of design is extracted from a plurality of image data having different resolutions prepared in advance. In this case, it is possible to reduce the time required for the scaling process of the image data in creating the image object.
