DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for sequentially drawing a plurality of image data in a display memory and displaying a plurality of figures respectively corresponding to the plurality of image data on a display unit corresponding to the display memory. The present invention relates to a graphic identification device that identifies a graphic corresponding to a designated position when a desired position of the display unit is designated, and particularly, when a plurality of displayed graphics overlap with each other, only a desired graphic can be efficiently displayed. The present invention relates to a graphic identification device for selecting an instruction.

[0002]

2. Description of the Related Art Conventionally, there has been known a technique of displaying a plurality of figures on a display of a computer or the like and executing an application corresponding to the designated figure when a user designates a desired figure with a pointing device or the like. I have.

[0003] For example, Japanese Patent Application Laid-Open No. Hei 3-22014 displays a graphic subjected to image processing such as enlargement / reduction, and displays the display position, shape, and shape of each item of a menu in a menu management table in accordance with the display result. A menu selection method is disclosed in which a value of an item content is changed and a process is determined based on the content of the changed menu management table and a coordinate value specified by a pointing device.

Here, in drawing such a figure, a method of reducing data relating to the figure by using some function (hereinafter referred to as a "function drawing method") or a method of displaying previously prepared image data ( Hereinafter, this will be referred to as an “image drawing method”).

[0005] Therefore, when determining whether or not a figure has been designated, it is checked whether or not the pointing coordinates of the pointing device are within a figure area in which a function or image is represented.

[0006]

However, the above-mentioned prior art does not consider the case where a plurality of drawn figures overlap each other, so that a measure for eliminating such overlapping of figures is required.

Specifically, there is a measure for redefining the graphic area so that an overlapping area does not occur. However, in order to perform such redefinition, every time one of the figures is moved, the graphic area is overlapped. It is determined whether or not the graphic area has occurred, and if an overlap has occurred, the graphic area must be redefined.

For this reason, when a graphic having a relatively complicated shape is expressed as a function, it takes time to redefine the graphics, which may cause a delay in the graphic identification processing.

Although a countermeasure to cope with such overlapping of the figures can be considered by selecting all of a plurality of overlapping figures, it is not appropriate to allow the user to select an unintended figure.

As described above, in the conventional graphic identification technique, it is not possible to efficiently identify a figure when a plurality of figures overlap, and it is important how to efficiently identify the figure in such a case. It has become a challenge.

SUMMARY OF THE INVENTION In view of the above, an object of the present invention is to provide a graphic identification device capable of efficiently indicating and selecting only an intended graphic when a plurality of displayed graphics overlap each other. And

A figure identifying apparatus 10 shown in FIG. 1 designates a figure (hereinafter referred to as an “object figure”) of an identification object displayed on a display 11 with a mouse 12 so that an appearance image of the designated figure is displayed. This is a device for displaying on the display 11.

More specifically, the figure identifying apparatus 10 previously stores appearance image data (hereinafter referred to as "image data") of each target figure in a memory 15 and sequentially superimposes the image data on a V-RAM. Write it and display it on the display 11. Note that the drawing order of the image data of each target graphic when the display is performed on the display 11 is stored in the drawing order storage unit 16.

Further, in addition to the above-mentioned image data, the figure identifying apparatus 10 uses the image data as an object area (hereinafter, referred to as “target area”) and a background area (hereinafter, referred to as “transparent area”). ) Are stored in the memory 15. Note that a pixel value “1” is assigned to the target area of the mask image data,
A pixel value '0' is assigned to the transmissive area.

Here, when the target graphic pointed by the mouse 12 is determined, the last drawn mask image data stored in the drawing order storage section 16 is determined.
Then, it is checked whether or not the designated coordinates of the mouse 12 are within the target area.

If the designated coordinates are within the target area, it is determined that the target graphic corresponding to the mask image data is specified by the mouse 12, and the image data of the target graphic is displayed on the display 11. .

On the other hand, if the designated coordinates are not within the target area, the drawing order stored in the drawing order storage unit 16 is traced in reverse, and the same processing is repeated until the target graphic is specified. It is determined which target graphic includes the designated coordinates.

As described above, in the present embodiment, the target graphic pointed by the mouse 12 is determined by using the drawing order of the image data, the mask image data of each target graphic, and the determination memory 18.

Acquires the mask image data of the target figure drawn last from the memory 15 based on the drawing order stored in the drawing order storage unit 16 (step 201).

After the acquired mask image data is developed in the discrimination memory 18 (step 202), the pixel value of the designated coordinates of the mouse 12 is obtained from the discrimination memory 17 (step 203).

Then, it is determined whether or not the pixel value is "1" (step 204). If the pixel value is "1", the designated coordinates are included in the determination area, and the pixel data corresponds to the mask image data. It is determined that the target graphic is the target graphic designated by the mouse 12 (step 205), and the process ends.

On the other hand, if the pixel value is "0", the designated coordinates are included in the transparent area, so the next target figure in the drawing order stored in the drawing order storage unit 16 is checked (step 206). Then, the mask image data of the target graphic is acquired from the memory 15 (step 207), and step 2 is executed.
02 and the same processing is repeated.

Then, even if the processing is performed on all the target graphics in the drawing order, if the corresponding target graphic cannot be specified, it is determined that there is no corresponding object (step 208), and the processing is terminated.
