Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention According to the present invention, even when a part of an original image is enlarged, the display information of the image displayed on the original image is not erased from the enlarged image. The present invention relates to an image processing device, an image processing method, and a recording medium.

[0002]

2. Description of the Related Art In recent years, with the widespread use of computers, images are frequently displayed on a display and used. In an application having an image display function or an image creation / modification application, the user may reduce an image to display the entire image, or conversely, enlarge the image to display a part of the image in detail.

For example, in the case of displaying a map, a reduced display is performed when information on a wide area is desired, and an enlarged display is performed when information on a narrow area is desired. Normally, the magnification is switched so that the display is performed at the desired magnification.

[0004]

For example, when the map is displayed on the screen and the reduced screen is switched to the enlarged screen, most of the information in the wide area displayed on the reduced screen is not displayed. Will be displayed. Therefore, in order to see the hidden image information again,
It is necessary to return the screen display from the enlarged screen display to the reduced screen display, or scroll the enlarged screen to display a desired portion.

When a computer or the like is used to refer to various system diagrams, various flowcharts, various design drawings, etc. in addition to ordinary maps, the display is enlarged and reduced in the same manner as described above, and the scale of the display is reduced. Is transformed.

On the other hand, images with different scales can be simultaneously displayed in different areas on the screen. In this case,
Since it is necessary to secure two display areas on one screen, the display area of each display area must be reduced.

There is also known a technique of designating a part of a region where an image is displayed, enlarging the designated region and pasting it on the original image for display. In this display technique, as shown in FIG. 1A, it is assumed that the region R1 (indicated by a circle in FIG. 1A) of the region in which the original image G5 is displayed is designated. In this case, the designated area R1
Image G1 is clipped, and as shown in FIG. 1B, this image G1 is enlarged to form an enlarged image G2,
This enlarged image G2 is pasted on the original image G5.

However, if the enlarged image G2 is pasted as it is on the original image G5 as shown in FIG.
As shown in (d), in the information of the original image G5, a region R3 sandwiched between the outer edge contour of the region R1 and the outer edge contour of the region R2.
Information in (hatched area) is erased.

The present invention has been made in view of the above problems, and an object thereof is an image which does not damage the information of the original image even if an enlarged image of an area in the original image is pasted and displayed. It is to provide a processing device, an image processing method, and a recording medium.

[0010]

In order to achieve the above-mentioned object, an image processing apparatus according to the present invention has an image display section for displaying an original image and a partial area of the image displayed on the image display section. The image processing apparatus includes an operation unit having an interface (point means such as a mouse and a raster pen) to be designated, and an image processing unit for enlarging an area designated by the operation and displaying the enlarged image on the image display unit. Then, the image processing unit enlarges the image of the first region designated by the operation unit so as to correspond to the second region including the first region, and the outer edge contour includes the second region. Then, the image of the third area whose inner edge contour is the contour of the first area is transformed so as to correspond to the fourth area in which the outer edge contour is the outer edge contour of the third area and the inner edge contour is the contour of the second area. Enlargement / deformation means for processing, an image subjected to enlargement processing corresponding to the second area, an image subjected to deformation processing corresponding to the fourth area, and the second of the original images.
Image combining means for combining the area and the image of the area excluding the fourth area.

For example, in the guide map or the like, by enlarging and displaying only the vicinity of the destination without missing the peripheral information, it becomes easy to confirm from the rough process of the whole to the detailed process of the vicinity of the destination. Further, in a normal image, partial enhancement can be easily performed by enlarging only a part of the image. Even for text data, it is possible to make small characters easy to read by partially enlarging.

In the image processing apparatus of the present invention, the enlargement / deformation means has a scale and / or a scale change rate of the image transformed corresponding to the fourth region such that the scale of the original image and / or the scale change rate of the original image at the outer edge contour portion. Alternatively, the image of the third region is subjected to a deformation process so as to be continuous with the scale change rate and to be continuous with the scale and / or the scale change rate of the image that has been enlarged corresponding to the second region in the inner edge contour portion. be able to.

As a result, the image at the boundary between the second region and the third region and the boundary between the second region and the region not subjected to the enlargement / deformation change smoothly, so that the process of the present invention makes it difficult to see the image. Such inconvenience does not occur.

According to the image processing method of the invention, the image of the first area designated by the operator is included in the second area including the first area.
An image of a third region in which the outer edge contour includes the second area and the inner edge contour is the contour of the first area, and the outer edge contour is the outer edge contour of the third area. There is a step of performing deformation processing in which the inner edge contour is associated with a fourth area that is the contour of the second area, an image that has been enlarged in association with the second area, and is deformed in association with the fourth area. It is characterized by including a step of synthesizing the processed image and the image of the fifth region of the original image excluding the second region and the fourth region.

Further, in the image processing method of the present invention, in the deformation processing step, the scale and / or the scale change rate of the image deformed corresponding to the fourth region is the scale of the original image at the outer edge contour portion. And / or the image of the third region is transformed so as to be continuous with the scale change rate and / or with the scale and / or the scale change rate of the image enlarged in correspondence with the second region in the inner edge contour portion. Can be given.

Further, the recording medium of the present invention stores a program for executing each of the above processes. The above program can be applied to a computer application such as a database, or can be incorporated as a plug-in such as a WWW browser.

Furthermore, in each of the above inventions,
"Scale and / or scale change rate" means "at least one of scale and scale change rate". And
As a general rule, "the scale and / or the scale change rate deformed corresponding to the fourth region is continuous with the scale and / or the scale change rate of the original image in the outer edge contour portion",
“The scale reduced corresponding to the fourth region and the scale of the original image in the outer edge contour portion are continuous” and “the scale change rate transformed corresponding to the fourth region is the same in the outer edge contour portion. Continuing with the scale change rate of the original image ”
That is, the scales and the scale change rates correspond to each other. This also applies to the inner edge contour portion.

However, between the outer edge contour portion and the inner edge contour portion,
"Scale" and "scale change rate" do not necessarily have to correspond. That is, for example, the scale may be continuous in the outer edge contour portion and the scale change rate may be continuous in the inner edge contour portion (or vice versa). Of course, it is preferable that they are unified in the arithmetic processing.

FIG. 2 shows a map database system using the image processing apparatus of the present invention. In FIG. 2, the image processing apparatus 1 includes a display unit 11, an operation unit 12, and
The image processing unit 13 and the memory 14 (ROM 14a, RAM
14b) and the mass storage device 15. An original image (map) is displayed on the display unit 11. The operation unit 12 is used when designating a predetermined area of the map in the present embodiment. The image processing unit 13 can clip a predetermined area of the original image and can perform enlargement processing and deformation processing on the clipped image. The ROM 14a stores image processing programs such as a map creation processing program and a scale conversion processing program. In this embodiment, the RAM 14b can be used as a temporary storage area for various calculation results and a work area. Mass storage device 15
Is a database (DB) in which a large number of maps are stored.

The basic operation of the image processing apparatus 1 shown in FIG. 2 will be described with reference to the flowchart of FIG. 3 and the image processing explanatory diagrams of FIGS. 4 and 5. First, the image processing unit 13
The data of the original image G5 to be processed is the mass storage device 1
It is assumed that the original image G5 is called by the RAM 14b from 5, and the original image G5 is displayed on the display unit 11. The image processing unit 13
Information (image G) of a region R1 (see FIG. 4A-1) to be enlarged in the original image G5 designated by the user from the operation unit 12
1) is acquired (ST101). The user can use an input device such as a mouse or a pen for this input.

Further, the image processing unit 13 acquires the enlargement ratio information input by the user from the operation unit 12, and uses it as RA.
The data is stored in M14b (ST102). Further, the image processing unit 13 obtains an area R2 when the specified area R1 is enlarged from the information of the specified area R1 and the enlargement ratio information specified by the user, and stores this area information in a predetermined area of the RAM 14b. .

Next, in the image processing unit 13, the outer edge contour is the contour of the area R2, the inner edge contour is the contour of the area R1 (see FIG. 1D), and the outer edge contour is the area R.
3 is a contour including the outer edge contour, and the inner edge contour is the region R
The region R4 that is the outer edge contour of 3 (that is, the contour of the region R2) is specified (ST103: see FIG. 4 (b-1)).
Here, the size of the outer edge contour of the region R4 may be fixed and set (for example, a size that is a predetermined multiple of the region R2), or the user may specify a set value from the operation unit 12. You may allow it.

After that, the image processing section 13 acquires data of all figures, characters, symbols and the like on the original image G5 (here, on the mesh including the regions R2 and R4) (ST104). The data acquired here is, for example, a control number, configuration coordinates, type, thickness, etc. of a diagram such as an electric wire / cable, such as an electric wire / cable, when the transmission / distribution system diagram is used. Coordinates, constituent coordinates, types, etc., management numbers of character string data, base point coordinates, font types, sizes, etc.

The image processing unit 13 defines a new mesh other than the currently displayed mesh on the memory, and separately copies the acquired mesh data to the RAM 14b (S
T105), the subsequent processing (coordinate conversion calculation) can be performed on the copied mesh. If the result of the coordinate conversion is not saved, the subsequent processing may be performed on the currently displayed mesh by the following steps.
There is no need to separately copy to 4b. Note that the currently displayed mesh is also stored in a predetermined area of the RAM 14b in this embodiment. Hereinafter, the image of the mesh to be processed stored in the RAM 14b will be referred to as a work mesh.

Next, regarding the work mesh, the region R
The image data included in 1 and the data included in the region R3 are acquired (ST106). That is, the image processing unit 1
3 is an image G1 of the region R1 as shown in FIG.
Is clipped and this is shown in FIGS. 4 (a-2) and (a-3).
The area R2 is mapped (enlargement processing) as shown in (1) to create an enlarged image G2. Further, the image G3 of the region R3 is clipped as shown in FIG. 4 (b-1), and this is mapped (transformed) to the region R4 as shown in FIGS. 4 (b-2) and (b-3). (ST107), deformed image G
Create 4. For polygons such as buildings and electric wires / cables, and line data that do not need to worry about shape deformation due to coordinate conversion, the image of region R1 corresponds to region R2 based on the calculation formula described later. Then, the image of the region R3 is deformed so as to correspond to the region R4.

The image processing section 13 calculates a scale value for each point of the area R2 and the area R4 for the polygon or line (ST108). Here, the scale of the region R2 is a single value over the region. Further, the scale of the region R4 is set to a value that is continuous with the scale of the original image in the outer edge contour portion and continuous with the scale of the image that has been enlarged in the inner edge contour portion so as to correspond to the region R4. The scale change rate can also be continuous with the scale change rate of the original image at the outer edge contour portion and continuous with the scale change rate of the image subjected to the enlargement processing corresponding to the region R2 at the inner edge contour portion.

For polygons or lines on the image mapped to the regions R2 and R4, the thickness of the polygons or lines is set according to the calculated scale value (ST1).
09). For example, if the line width of a polygon or line is the area R
2 and the scale value in the region R4,
The line width can be set so that the appearance has a constant thickness.

On the other hand, when the object is a character or a symbol (for example, a symbol), steps 107 to 107 are executed.
Instead of step 109, step 110 to step 1
12 is performed. That is, for objects such as power distribution equipment symbols and character string data that have a distorted shape due to coordinate conversion and have an effect on the appearance, the coordinates of the base point (for example, , The center of the character or symbol or the coordinate of the upper left corner) is calculated (ST11)
0).

For the characters and symbols after the coordinate conversion, the scale value when they are arranged in the regions R2 and R4 is calculated (ST111). Then, for the characters / symbols newly formed in the regions R2 and R4, the line width of the characters / symbols is set according to the calculated scale value (ST11).
2). Further, the shapes of the characters and symbols can be set so that the shapes of the characters and symbols do not depend on the scale values in the regions R2 and R4, and the appearance is a normal shape.

The images G2 and G4, which have undergone the enlargement processing and the deformation processing in steps 107 to 109 and 110 to 112, are mapped to the corresponding regions of the work mesh (ST113), and are replaced with the currently displayed mesh. Display the work mesh (ST11
4). When the mesh is copied in step 105, the data on the work mesh is registered in the DB so that the data can be read as necessary.

FIG. 5A shows an image obtained by mapping the enlarged image G2 and the deformed image G4 on the original image G5. When performing the transformation process on the region R3, FIG.
As shown in, the scale and scale change rate of the image are continuous with the scale and scale change rate of the original image in the outer edge contour portion,
The scale and the rate of change of scale of the image G2 that has been subjected to the enlargement processing corresponding to the region R2 in the inner edge contour portion can be made continuous. Further, when performing the deformation process on the image of the region R3, as shown in FIG. 5C, the scale change rate of the image becomes discontinuous with the scale change rate of the original image at the outer edge contour portion, and at the inner edge contour portion. It is also possible to set the scale so as to be discontinuous with the scale change rate of the image G2 that has been subjected to the enlargement processing corresponding to the region R2.

An embodiment in which the regions R1 to R4 are similar ellipses will be described below with reference to FIG. In addition,
For reference, FIG. 6 (b-1), (b-2), (b-
Regions R1, R2, R3 and R4 are extracted and shown in 3) and (b-4). Ellipse A: contour of region R1, contour R of inner edge of region R3 ellipse B: contour of region R2, contour of inner edge of region R4 ellipse C: contour of outer edge of region R3, contour of outer edge of region R4 O (Xo, Yo): origin of ellipse p: major axis length of ellipse A q: minor axis length of ellipse s × p, s × q: major axis length of ellipse B, minor axis length t × p, t × q: major axis length of ellipse C, short Axis length M (Xm, Ym): Arbitrary point I (Xi, Yi) in region R1: Coordinate N (Xn, Yn) when pixel of coordinate M (Xm, Ym) of region R1 is remapped to region R2 ): Arbitrary point J (Xj, Yj) in the region R3: Coordinate P (Xp, Yp) when the pixel of the coordinate N (Xn, Yn) of the region R3 is remapped to the region R4: Long axis of the ellipse A End point Q (Xq, Yq): Short axis end point of ellipse A S (Xs, Ys): Long axis end point of ellipse B T (Xt, Yt): Long axis end of ellipse C Straight line K: Straight line passing through origin O and point M Straight line L: Straight line passing through origin O and point N A (Xa, Ya): Contact point between ellipse A and straight line B (Xb, Yb): Contact point between ellipse B and straight line L C (Xc, Yc): contact point between ellipse C and straight line L: angles p and q generated between the long axis of the ellipse and a straight line parallel to Y = 0 are (1-1), (1-2) ) Is calculated.

2), (2-3), and (2-4).

[0035]

[Equation 2]

An algorithm for expanding the region R1 to the region R2 will be described below. The ellipse A which is the contour of the region R1 is expressed by the equation (3-1), and the ellipse R2 which is the contour of the region R2 (enlarged region of the region R1) is expressed by the formula (3-2).

[0037]

[Equation 3]

Here, arbitrary coordinates M included in the region R1
(Xm, Ym) is included in the ellipse A, and the equation (4) is satisfied.

[0039]

[Equation 4]

When the pixels on the region R1 are remapped to the region R2, the pixel on the coordinate M (Xm, Ym) is the origin O.
On a straight line K passing through the coordinates M and M, it moves in a direction away from the origin O according to the distance from the origin O. Figure 6
In (a), the pixel on the coordinate M (Xm, Ym) is the coordinate I (X
The state of being moved (mapped) to i, Yi) is shown. Pixels in the region R1 on the origin O do not move even if they are remapped. Also, the region R on the ellipse A
When the pixel of 1 is remapped, it moves to the intersection of the straight line K and the ellipse B. The coordinates I (Xi, Yi) are expressed by the equation (5).

[0041]

[Equation 5]

As a result, the pixel of arbitrary coordinates M (Xm, Ym) included in the region R1 has the coordinates I in the region R2.
It will move to (Xi, Yi) (Fig. 6 (b-
1), (b-2)). Next, a case where the pixels of the image of the region R3 are mapped (deformed here) to the region R4 will be described below.

Ellipse C slightly larger than ellipse B
Is given by equation (6).

[0044]

[Equation 6]

Arbitrary pixel (coordinate N
Consider (Xn, Yn)). Since this pixel is outside the ellipse A and inside the ellipse C, equations (7-1) and (7-
2) Formula is materialized.

[0046]

[Equation 7]

Mapping the pixels included in the region R3 to the region R4 means that the pixel having the coordinates N (Xn, Yn) is far from the origin O on the straight line L passing through the origin O and the coordinates N (Xn, Yn). Is to move in the direction. If the pixel is on the ellipse A (the coordinates N (Xn, Yn) are on the ellipse A), the pixel moves on the ellipse B, and if the pixel is on the ellipse C, the pixel does not move. Further, as described with reference to FIG. 5, the scale and the scale change rate of the image in the region R4 are continuous with the scale and the scale change rate of the original image in the outer edge contour portion, and are enlarged corresponding to the region R2 in the inner edge contour portion. It can be made continuous with the scale and scale change rate of the processed image.

When the deformation processing is performed on the area R3, the scale change rate of the image becomes discontinuous with the scale change rate of the original image at the outer edge contour portion, and the enlargement processing is performed corresponding to the area R2 at the inner edge contour portion. It is also possible to set the scale so as to be discontinuous with the scale change rate of the image made. Assuming that the coordinates of the point to which the pixel of the coordinates N (Xn, Yn) on the area 3 has moved are J (Xj, Yj), Xj, Yj are
It is expressed by equations (8-1) and (8-2).

[0049]

[Equation 8]

Next, FIGS. 7A to 7F show an example of processing when the user specifies the region R1 and an operation when the user specifies the region R2. First, the user designates the end point of the area to be enlarged with a mouse click (FIG. 7A). Next, the mouse is clicked and dragged to the other end point of the area to be enlarged, and when the end point is reached, the dragging is released (FIG. 7B). At this time, the ellipse is displayed by default, and the long-axis two end points and the short-axis one end points (intermediate points) of the ellipse are clearly shown (FIG. 7C).

Then, the size of the ellipse A is adjusted by dragging the one end point (intermediate point) of the minor axis up and down while clicking the mouse. At this time, the ellipse A is fixed at the point where the mouse click is released. As a result, the region R1 is determined (FIG. 7 (d)).

After this, a rectangle surrounding the ellipse A is displayed and 4
The end points of the corners are specified (FIG. 7 (e)). Then, while dragging any of the four corners in the enlargement direction with the mouse clicked, the size of the ellipse to be enlarged is adjusted. At this time,
The ellipse B is fixed at the point where the mouse click is released. As a result, the region R2 is determined (FIG. 7 (f)).

The ratio between the ellipse A and the ellipse B determines the ellipse C according to a predetermined enlargement ratio. As a result, the regions R1, R2, R3 and R4 are determined.

The positions of characters and various symbols are specified by the pixel serving as the base point. When the coordinates of the constituent pixels of the characters / symbols included in the region R1 and the region R3 are converted by the above-described algorithm, the original shape is lost and distorted. Therefore, in consideration of legibility, with respect to characters and symbols, the base point of the algorithm described above is converted, and the characters and symbols are converted into a size corresponding to the scale value at the coordinates of the conversion destination without losing the shape.

For example, assume that there is a square symbol as shown in FIG. The shape of this is determined by the base point coordinates (for example, the coordinate a at the upper left corner) and the coordinates forming the other symbols (for example, the coordinates b, c, d at the remaining three corners). If these coordinates are changed by the above-mentioned algorithm (the four corners after the change are a ', b', c ', d'
As shown in FIG. 8B, since the scale is changed depending on the coordinates, the characters / symbols are distorted.

Therefore, as shown in FIG. 8C, only the base point coordinate a is moved to the point a'by the above-mentioned algorithm,
Other components move while maintaining the positional relationship according to the scale value of the base point coordinates. This makes it possible to move characters and symbols while maintaining a smooth appearance.

The scale value Z'at the movement destination of the base point coordinate is
It is given by the equation (9). In the equation (9), z is the scale before processing, and s is the scale after processing at the base point.

[0058]

[Equation 9]

Depending on the scale at this destination, the characters
You just have to construct the symbol.

An example of actual image conversion using the apparatus of the above embodiment is as shown in FIG. 9, for example. That is, as shown in FIG. 9 (a), a predetermined area of the map which is entirely displayed at the same scale (area circled in the figure)
9 is specified and the specified area is enlarged, FIG.
As shown in (b), the designated area is enlarged and the surrounding area is compressed and deformed for display. As is clear by comparing FIG. 9A of the original image with FIG. 9B after the processing, all the information displayed in the original image is displayed without being hidden. In this example, the scale of the area around the enlargement target is gradually changed and is not continuous. Of course, you may make it continuous.

Another example is shown in FIG.
As shown in (a) and (b), it is of course possible to process a one-dimensional original image. In FIG. 10A, when the character string is enlarged, a part of the original character string is erased by the enlarged image. However, when the apparatus of the above-described embodiment is used, As shown, all the information displayed in the original image is displayed without being hidden.

[0062]

Since the present invention is configured as described above, the information of the original image will not be lost even if the enlarged image of the area in the original image is pasted and displayed. Therefore, in the guide map or the like, by enlarging and displaying only the vicinity of the destination without missing the peripheral information, it becomes easy to confirm from the rough process of the whole to the detailed process of the vicinity of the destination.
Furthermore, in a normal image, only a part of the normal image is enlarged to facilitate partial emphasis, and also for text data, partial enlargement makes it easier to read fine characters.
