C. Processing procedure of the first embodiment: FIG.
6 is a flowchart illustrating a processing procedure according to the embodiment. In step S1, the moving amount of each image component in creating a bird's-eye view image part _{P 1 ~P 3 (DX, DY} ) an operator designates. Here, DX indicates the amount of movement in the horizontal direction, and DY
Indicates the amount of movement in the vertical direction. The movement amount (DX, D
As Y), a preset initial value can be used.

When the operator instructs the display of the bird's-eye view in step S2, the bird's-eye image data creating unit 44 starts the processing of displaying the bird's-eye view according to the instruction. The processing after step S2 is processing that the bird's-eye image data creating unit 44 automatically performs.

In step S3, the number N of image parts arranged in the page is obtained. This processing is performed by checking the number N of the component information included in the page information 100 (FIG. 3). Then, as shown in step S4, the processing of steps S5 to S7 is repeated N times while sequentially changing the overlapping order i from 1 to N.

First, in step S5, the overlapping order is i
The display offset position for the image component P _i is obtained. The offset position _{OP i (X i, Y i} ) as, for example the lower left point of the image components P _i is used (Figure 2). In step S6, the image component P _i in the bird's eye view
The offset position ^{_{OP i '(X i',}} Y i ') was calculated according to the following formula, offset position OP ^_i' the image components P _i
Image part P _i in the frame memory 26 to place
Draw bitmap data of

X _i ^′ = X _i + DX · i (1a) Y _i ^′ = Y _i + DY · i (1b)

That is, the position of the i-th image component P _i is set so as to be sequentially shifted by the moving amount (DX, DY) from the image component P _i-1 having the immediately preceding overlapping order. In step S7, it is determined whether all the image parts in the page have been displayed. If there is an image component that is not displayed, the process returns to step S4 and the process is repeated. If all image components are displayed, the process ends (step S8).

FIG. 5 is an explanatory diagram showing an example of a screen on which a bird's-eye view is displayed. In this example, a first window W1 for displaying a page image and a second window W2 for displaying a bird's eye view are simultaneously displayed on the screen. The drawing of the bird's-eye view is performed in the second window W2.

In the second window W2, each of the image components P _{1 to} P ₃ is displayed in a reduced size, and the offset position OP _i ^′ of each image component is set according to the above equations (1a) and (1b). Is set. The bird's eye view displayed on the second window W2, although three image components P ₁ to P ₃ are overlapped sequentially in part, each image component, at least a portion each not hidden in the other image part In state. Thus, the operator, by viewing the bird's-eye view, it can be confirmed that the second image component P ₂ is present under the third image part P _3. Note that, even when the bird's-eye view is created, the page image in the first window W1 is kept as it is. That is, in the first embodiment, since the bird's-eye view is separately created without changing the arrangement of the image parts in the page, the image parts hidden under other image parts are confirmed using this bird's-eye view. It is possible to

In the bird's eye view, each image component may be displayed without being reduced. Further, it is not necessary to display the first window W1 representing the page image and the second window W2 representing the bird's-eye view side by side. When the second window W2 is displayed, the first window W1 is made invisible. You may. However, two windows W
By displaying 1 and W2 side by side, there is an advantage that the overlapping state of the image parts can be more easily recognized.

D. FIG. 6 is a flowchart showing the processing procedure of the second embodiment. This second
In the embodiment, in addition to the procedure of the first embodiment, a step of selecting an image component in the bird's-eye view is added. That is,
Steps S1 to S8 are the same as those in the first embodiment, and steps S9 and subsequent steps are added. However, in step S6, the pit map data of each image component used in the bird's-eye view is held in the main memory 24.

In step S9, the operator selects an image component by hitting a desired image component at the position TP in the second window W2 (FIG. 5) using the mouse pointer. In step S10, the coordinate value (PX, P
Y) is obtained. Then, as shown in step S11, the processes in steps S12 to S14 are repeated N times while sequentially changing the overlapping order i from 1 to N. In step S12, the hit position TP (PX, P
Y) is by examining whether present on the i-th image part P _i of the bitmap image, whether the i-th image part P _i is selected or not. When the hit position TP (PX, PY) is present on i-th image part P _i of the bitmap image, it is judged that the the image component P _i is selected, the process ends in step S16 I do. Hit position TP (PX, PY) when is not on the i-th image part P _i of the bitmap image, performs a check of the number of image parts in step S14, if examined all image parts , Step S
At 15, the process ends. On the other hand, if there are remaining image components, the process returns to step S11 to repeat the processes of steps S12 to S14.

As described above, in the second embodiment, the operator can select a desired image component from the bird's-eye view. For example, the in the first window W1 and the second image component P ₂ can not be selected since hidden by the third image component P _3, it is in the second window W2 of the second image component P ₂ You can select this because some are visible. Then, the second image selected part P _2,
A desired process (for example, the overlapping order is set to the third image component P ₃
Processing for changing to a higher, processing for deleting the image component P ₂₎ can be performed. Thus, in the second embodiment, it is possible to, without changing the other position of the image components P _1, P ₃ in the page, the desired processing by selecting the image part P _2, which was hiding running .

E. Processing procedure of third embodiment: FIG.
6 is a flowchart illustrating a processing procedure according to the embodiment. In the third embodiment, a bird's-eye view of a designated area is displayed instead of a bird's-eye view of the entire page. First, in step S21,
Movement amount of each image component in creating a bird's-eye view image part P ₁ to P ₃ and (DX, DY) operator designates. In step S22, the operator sets an area for displaying the bird's-eye view (bird's-eye display target area). FIG. 8 is an explanatory diagram showing the processing content of the third embodiment. In this example, a rectangular bird's-eye view display target area WW is specified in the page image in the first window W1. Hereinafter, an image portion included in the bird's-eye display target area WW of each image component is referred to as a “bird's-eye display portion”.

In the lower half of the bird's-eye display target area WW, the second
Image parts P ₂ of does not exist. In this case, the bird's-eye display portion P _2a of the second image component P ₂ is
It has the same size as W, the lower half of which is a blank image. Similarly, the lower end of the bird's-eye display target area WW, third image component P ₃ of no. Therefore, the third image component P
_{The third} bird's-eye display portion _P3a is partially blank at the lower end.

Next, in step S23, when the operator instructs the display of the bird's-eye view, the bird's-eye image data creation unit 4
4 starts the bird's-eye view display processing in response to this instruction.
In step S24, the number N of image components at least partially included in the bird's-eye display target area WW is acquired. Then, as shown in step S25, the processing of steps S26 to S28 is repeated N times while sequentially changing the overlapping order i from 1 to N.

In step S26, an offset position for display is acquired for the image component P _i having the overlapping order i. As the offset position OW (Xw, Yw),
For example, the lower left point of the bird's eye display target area WW is used (FIG. 8). In step S27, the image component P in the bird's-eye view
_i offset position ^{_{OW i '(Xw i',}} Yw i ') , and calculated according to the following equation, the offset position OW ^_i' draws the bird's-eye view portions of the image components P _i in.

[0042] ^{_{Xw i '= Xw + DX ·}} i ... (2a) Yw i' = Yw + DY · i ... (2b)

That is, the position of the bird's-eye display portion _Pia of the i-th image component P _i is sequentially shifted by the moving amount (DX, DY) from the bird's _- eye display portion of the immediately preceding overlapping image component P _i-1. Set to go. In step S28,
It is determined whether all the image parts in the page have been displayed. If there is an image part that has not been displayed, the process returns to step S23 to repeat the processing. If all the image parts have been displayed, the processing ends (step S2).
9).

The bird's-eye view displayed in the third embodiment is shown in the second window W2 of FIG. In this bird's-eye view, bird's-eye view portion P _1a to P _3a of the image components are displayed sequentially shifted state. The operator, by viewing this bird's-eye view, it can be confirmed that the second image component P ₂ is present under the third image part P _3. According to the third embodiment, as in the first embodiment, it is possible to check the image parts hidden under other image parts without changing the arrangement of the image parts in the page. However, in the third embodiment, since the processing target is limited to the image portion in the bird's-eye display target area WW, there is an advantage that the processing time can be reduced. On the other hand, in the first embodiment, since the entire image component is displayed as a bird's-eye view, there is an advantage that the relationship between the image components can be more easily recognized.

F. FIG. 9 is a flowchart showing a processing procedure of the fourth embodiment. In the fourth embodiment, in addition to the procedure of the third embodiment, a step of selecting an image component in the bird's-eye view is added. That is, the processes of steps S21 to S29 are the same as those of the third embodiment, and thereafter, steps S9 to S16 are added.
However, in step S27, the pit map data of each image component used in the bird's-eye view is held in the main memory 24. Steps S9 to S16 are performed in the second
This is the same as steps S9 to S16 in the embodiment (FIG. 6).

In the fourth embodiment, when determining whether or not the i-th image component has been selected in step S13,
It is sufficient to check the bitmap data of the bird's-eye display portion, and it is not necessary to check the entire image component. Therefore, there is an advantage that the processing time can be reduced as compared with the second embodiment.

G. FIG. 10 is a flowchart showing a processing procedure of the fifth embodiment. Fifth
In the embodiment, in order to make each image component more visible,
The moving amount of the image component is adjusted. First, step S3
In step 1, the bird's-eye image data creating unit 44 obtains the number N of image parts in the page, and in step S32, the moving amount (D
X, DY). As a method of this adjustment, there are various methods as exemplified below.

(1) The value of the standard movement amount (DX, DY) is displayed on the screen, and the operator can use the keyboard 30 or mouse 3
Adjust the value using 2. (2) By dividing a value obtained by subtracting a certain set amount from the width and height of the second window W2 for displaying the bird's-eye view by the number N of image parts (or any number M equal to or more than N). The movement amount (DX, DY) is automatically determined.

By adjusting the movement amounts (DX, DY), the overlapping of the image parts cannot be eliminated even in the bird's-eye view, and the overlapping state of the image parts is difficult to recognize because the image parts are too far apart. It is possible to solve such a problem.

When the operator instructs the display of the bird's-eye view in step S33, the bird's-eye image data creation unit 44
The display processing of the bird's eye view is started according to this instruction. The subsequent steps S4 to S8 are the same as steps S4 to S8 in the first embodiment shown in FIG. In the fifth embodiment, it is possible to set a bird's-eye view display target area as in the third and fourth embodiments.

The present invention is not limited to the above-described examples and embodiments, but can be implemented in various modes without departing from the scope of the invention.

(1) In the above embodiment, part of the configuration realized by hardware may be replaced by software, and conversely, part of the configuration realized by software may be replaced by hardware. You may do so.
