Description

[Detailed Description of the Invention] [Field of Industrial Application] The present invention relates to a method for managing image data of natural images by a processing device such as a workstation or a personal computer (personal computer). The present invention relates to an image processing apparatus and an image data management/processing method suitable for associating images with each other and efficiently performing operations such as processing, processing, and display of one image.

[Prior Art] Currently, systems that provide information using natural images on personal computers and workstations have been put into practical use. In this system, when editing images, for example, cutting out partial images, compositing, toning, and adjusting chromaticity, the cut out partial images are used as image data.
Must be stored and managed in separate files.

As a conventional technique related to image data management and processing methods, for example, there is a technique described in Japanese Patent Application Laid-Open No. 63-253477.

The technical example described in JP-A No. 63-253477 is aimed at image retrieval, and is capable of identifying an original image and a processed image that has undergone processing, and providing a pointer to the original image of a processed image. Information has been added.

On the other hand, when dealing with figures such as computer graphics, unlike natural images, elemental figures are combined,
Generate the desired complex figure.

For this purpose, a common method is to set several independent coordinate systems and a coordinate system for defining their relationships and perform modeling.

In this way, in the case of computer graphics, in order to synthesize composite figures from elemental figures that are parts, and to use elemental figures as independent parts, each figure has other figures. does not stipulate the relationship with Instead, the side that defines the composite shape to be generated using the element shape,
A management structure is used that describes the relationship between the coordinates of elemental figures.

Further, as a technique for handling images and figures in a composite manner, there is a technique described in, for example, Japanese Patent Laid-Open No. 1-263770. This extracts figures etc. from an image (binarized image), converts them into figure information, and then stores the figure information.

At the same time, topological information such as the connection relationship and positional relationship of each figure in the original image is extracted and stored, and then used for searching.

Similarly, map information that uses both graphics and images, or satellite images (remote sensing images) that are generated based on measurement information, have absolute coordinates as well as relative relationships between partial images. For extremely important images, a single world coordinate system (in the case of maps and remote sensing images, a spherical coordinate system of latitude and longitude) is used to manage the coordinates of each partial image.

[Problem to be solved by the invention]

The original image is decomposed into multiple partial images, and these partial images are
When using multiple partial images for various purposes such as natural image compositing processing, apart from using this partial image alone, it is necessary to check the geometric relationship of each partial image. It is necessary to preserve it, manage it, and use it.

In general image data management methods, the image data management structure of a partial image does not manage its relationship with the original image, particularly its geometric relationship.

For example, the image data management method described in Japanese Unexamined Patent Publication No. 63-253477 is aimed at image retrieval, and partial images of natural images are
It is a cropped image, and no consideration is given to the relationship with the original image, especially the relationship between coordinates.

In addition, when dealing with figures such as computer graphics, relationships with other figures are not defined for each element, and the side that defines the composite figure to be generated using its element figures is
A management structure is used that describes the relationship between the coordinates of elemental figures.

Furthermore, in map information or remote sensing images, coordinates of each partial image are managed using a single world coordinate system, and the relationship between the original image and the partial image is not defined.

In this way, in conventional image management methods, the image data management structure of partial images does not manage the relationship with the original image, especially the geometric relationship, so it is difficult to manage the relative relationships of multiple partial images. It is not possible to save and process the partial image. Therefore, it is usually best to manage the partial image as a single image without separating it into multiple parts, and then cut out and use the partial image when using it. Boat fishing.

However, the method of cutting out images when used takes time and is not efficient, and it is more effective to manage partial images from the beginning.

When managing partial images, one possible method is to use a relational database or the like. That is, it is possible to manage parent-child relationships, coordinate relationships, etc. between original images and partial images, and perform image processing using logical relationships such as parent-child, siblings, etc., and geometric relationships. Although the database described in the above-mentioned Japanese Patent Application Laid-open No. 1-263770 is slightly different in function, it is a type of database having such a purpose, and it is possible to perform processing by correlating parts with each other.

However, in order to make this possible, it is necessary to newly construct a database management mechanism.

The purpose of the present invention is to solve the problems of the prior art, to manage divided image data in a mutually related manner without requiring a new database management mechanism, and to improve efficiency by using partial areas of an image. An object of the present invention is to provide an image processing device and an image data management/processing method thereof that enable good image processing.

〔Example〕

Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.

FIG. 1 is a block diagram showing an embodiment of the constituent parts of an image processing system according to the present invention.

An image processing device 1 that processes image information, an image display device 2 that displays image data processed by the image processing device 1, and a user inputting position information of the image while viewing the image displayed on the image display device 2. A mouse 3 is used as a coordinate position input device for inputting data, a keyboard 4 is used by the user to input character codes, an external storage device 5 is used to store various data including image data, and The image input device 6 is configured to convert image data into image data.

The image processing device 1 also performs image processing such as image cutting and compositing based on an image input 1113 that receives and receives image data read by the image input device 6, and operation instruction input via the mouse 3 and keyboard 4. The image processing section 11 includes an image data processing section 11 that performs editing processing, and an image attribute processing section 7 and an image management section 12 that perform processing related to the present invention.

The image attribute processing section 7 includes an origin setting section 8 that sets position information of the image data in the image data input via the image input device 6, and similarly sets image coordinate transformation parameters such as size to the input image data. The coordinate conversion parameter setting section 9 sets the coordinate transformation parameters, and the image attribute information reading section 10 reads the image attribute information when editing an image.

The image attribute processing section 7 and the image management section 1 with such a configuration
2 executes processing according to the present invention.

That is, the origin indicating the display position of the image displayed on the screen of the image display device 2, or the display position corresponding to the original image of a partial image cut out by the cut-out process using this image as the original image, for example, This is set using the origin setting section 8.

Further, a coordinate transformation parameter setting section 9 sets coordinate transformation parameter information such as the size and scaling ratio of each of the original image and partial images. Furthermore, the image management unit 12
These image attribute information are added to the header information of the image data, and the image data and the image attribute information are associated with each other. When performing image processing, the image attribute information reading section 10 reads this header information.

Note that the image management section 12 does not directly add image attribute information consisting of position information and image coordinate transformation parameters set in the origin setting section 8 and coordinate transformation parameter setting section 9 to the image data as header information. It may also be managed using a table associated with each image data. This table may be stored in the memory within the image processing device 1 or in the external storage device 5. This management method will be explained in detail in FIG. 7, which will be described later.

The following explanation relates to the case where header information is added to image data.

The operation of an image processing apparatus l provided with such an image attribute processing section 7 and an image management section 12 will be explained.

First, image data received from the image input device 6 is inputted via the image input section 13 and stored in the external storage device 5. In this case, the origin setting section 8, the coordinate transformation parameter setting section 9, and the image management section 12 of the image attribute processing section 7, for example, write the display position and size of the image consisting of this image data in the header of the image data. Attribute information indicating the size etc. is added and stored. This header information is then used for subsequent management.

When performing image processing, the image attribute information reading section 10 of the image attribute processing section 7 reads header information, identifies image data based on the result, and processes each image data.

As shown in FIG. 5, which will be described later, this header information includes a label indicating that the content of the file is an image, a management identification number for identifying the image data itself, and the data format type. The image size, the enlargement/reduction ratio from the original image, the cutting origin from the original image, the original image file name, etc. are recorded.

Incidentally, if the image data is an original image, the recording of the cutting origin, etc. may be omitted, or the conditions input from the input device, the name of the image original, etc. may be recorded.

In the following, a case will be explained in which this image processing system uses the original image as a common reference coordinate system, cuts out partial images from the original image, stores these images, and further generates a composite image from these partial images. .

In other words, information such as position information and scaling ratio used to associate this cut out partial image with the original image is stored as attribute information, for example, attached to the header of each image data. We will explain the process of generating a new image by performing editing such as enlarging, reducing, toning, and compositing using an image.

FIG. 2 is a flowchart showing one embodiment of the processing operation of the image processing apparatus shown in FIG. 1 according to the present invention.

This embodiment uses an original image as a common reference coordinate system, and shows a processing operation in which partial images are cut out from this original image and these images are stored.

Here, it is assumed that the image data of the original image has already been input and stored.

First, read the original image and display it (step 201
). The region origin and size to be cropped, the original image file name, etc. are specified using the mouse 3 in FIG. 1 (step 2o2), and a partial image is cropped and displayed on the display device 2 in FIG. 1 (step 203). ).

In this case, when cutting out along the outline of an object, area segmentation is performed manually using a mouse or by an automated program, but here, it is assumed that the area is cut out into a rectangular shape.

Next, attributes such as the origin, size, and original image file name specified in step 202 are written in the header of the image data (step 204), and the file name is specified and stored (step 205).

Next, processing operations for generating a composite image using the stored original image data and partial image data will be explained.

FIG. 3 is a flowchart showing an example of the image synthesis processing operation of the image processing apparatus shown in FIG. 1 according to the present invention.

First, a background image, a plurality of partial images to be combined, a combination mode, etc. are specified (step 301), and these images are read out and displayed (step 302).

Next, the coordinate relationship for compositing is determined based on the combination of the original image recorded in the partial image, attribute information such as cutting conditions, and the compositing mode, and compositing is performed (step 303).

Then, new attribute information is added and stored in a file in the external storage device 5 shown in FIG. 1 (step 304).

In this case, change the file name of the background image and, if necessary,
The file name of the composite partial image is recorded as family file attribute information.

FIG. 4 is a flowchart showing the compositing process in FIG. 3 in more detail.

First, specify the synthesis position (Xs, Ys) in step 40.
1) Next, check the mode specified in step 301 in Fig. 3 (step 402) If the 6 mode is group composition, cut out the partial image "l" from the original image at the origin (Xi, Yi) as the relative origin of the partial image (step 403), shift by the synthesis position (Xs, Ys), and set the point (X s +X1, Ys+Yi) to one partial image r.
i'' as the origin of synthesis (step 404), and synthesize and display (step 405).

In this case, (Xi, Yi) is large due to the original image size of the partial image as a part, and depending on the compositing position, the specified point may protrude from the background image to be composited, so in this case, , among the set of partial images, rX r
Combination of the minimum values of J and rYiJ (Xmin,
rXiJ, r of each partial image by Ym i n)
Processing is performed by subtracting from Y i J.

After that, it is determined whether there are any remaining partial images (step 4).
06) If there is, the process returns to step 402 and the above process is repeated to synthesize the partial images of the Noh. If not, the process ends.

On the other hand, if the mode specified in step 301 of FIG. 3 is for independent compositing (step 402), the cutout origin of the partial images is ignored and the composite display is performed individually.

That is, set the partial image origin to (Olo) and step 40
7), set the composite display origin to (Xs, Ys) (step 408), and composite the partial image "lj" (step 409).
), In this way, the partial images are synthesized.

Note that when recording and saving the composition conditions of the composite image, the composition conditions are recorded as part of the header information for each background image and component image. This allows it to be used for changing synthesis conditions later.

Next, the image data processing and management method of the present invention using the image processing system shown in FIG. 1 will be described in more detail.

FIG. 5 is an explanatory diagram showing an example of the contents of header information set in the image processing apparatus in FIG. 1.

This header information 50 includes a file attribute 51 that indicates that the content of the file is an image, a management identification number 52 that indicates the file number of the main image data, and a cutting origin that indicates position information in the original image that is a reference shore reference system. (X,Y)53
, the cropping size (W,
H) 54, Enlargement/reduction ratio of the cut out image with respect to the original image (
Rw, Rh) 55, and an original image file name 56 indicating the management identification number 52 of the original image from which the main image data is extracted. Then, this header information 50 is converted into image data 5
7 and constitutes an image data file 58.

Note that the header information may further include data format type, input, or processing date and time.

In addition, if the image data is an original image, its cutting origin 5
For items such as 3, the recording may be omitted, or the conditions input from the input device, the name of the image original, etc. may be recorded.

In this way, a header is added to the image data and used for subsequent management and image processing.

The operation of the image processing system shown in FIG. 1 based on the header information shown in FIG. 5 will be described below using a specific example of image processing.

FIG. 6 is an explanatory diagram showing an example of a specific image processed by the image processing system shown in FIG.

In this example, partial images 61 to 64 are cut out from the original image 60 and saved as new images, and a new composite image 66 is created using these partial images 61 to 64 and a background image 65. It shows the geometric relationships to be synthesized.

Partial image 61 is an image cut out into a rectangle, partial image 6
2 to 64 show cases in which only the area of a specific object in the original image 60 is cut out, and the cutting origin in the coordinate shape of each original image 60 is the partial image 61 (x
, 1, Yl,), and the partial image 62 is (X, , , Yl,),
The partial image 63 is (X,,Y,,), and the partial image 64 is (
X14, Yl,).

Similarly, the horizontal and vertical sizes of the partial image 6I are (W
, 1, Hl,), the horizontal and vertical sizes of the cutout of the partial image 62 are (W23, Hl,), the horizontal and vertical sizes of the cutout of the partial image 63 are (Wll, Hl), and the partial image 64
The horizontal and vertical sizes of the cutout are expressed as (W, 4, H14).

Further, the scaling ratio of each partial image from the original image is shown in the header information 50 of FIG. 5, for example, the scaling ratio of the partial image 61 is (Rw, , Rh, ,
), the scaling ratio of the partial image 62 is (Rw, , Rh, ,
) 1 partial image 63 enlarged cotton! ”1 rate is (Rw, , Rh
, ,), the enlargement/reduction ratio of the partial image 64 is (Rw, ,,Rh
, ) etc.

However, the horizontal and vertical sizes (W, H) of the image cutout may be given as enlarged or reduced sizes, or may be given as converted sizes instead of ratios.

Furthermore, since data outside the object area does not exist in the partial images 60 to 64, the partial images are assumed to be virtual frames indicated by broken lines with the cutting origin (X, Y) as a reference.

The synthesis screen 66 shows an example of cutting out and compositing images using the above-mentioned attribute information.
Partial images 62 to 64 cut out from o are combined with another background image 65.

Here, the partial images 62 to 64 are the same car body,
Geometrically, the relationship between the front and rear wheels is unique. Therefore, by adjusting all the origins by the same amount, it is possible to easily reconstruct the partial images that have been disassembled in this way in the pond environment.

In this way, according to this embodiment, even if a part of the interior of a partial image disappears due to a processing error or the like and the data of the original image is required, the geometric relationship with the original image can be Since the relationship remains, it is only necessary to import the first part from the original image, and there is no need to re-cut it.

In a case like this, you can simply store only the region information in a file as a partial image and retrieve the actual data as needed.This region information also contains the above-mentioned information as header information, just like the partial image. It is also possible to record.

That is, in addition to enlarging and reducing them as partial images.

This embodiment is applied to data that has undergone various image processing such as image quality adjustment and area extraction information.

The above example shows the case where attribute information is recorded in the header stored in the same file as the image data, but this attribute information can also be stored and managed as image management data in a file separate from the image data. is also possible.

The following describes the management of image attribute information when the image attribute information is stored in a file separate from the image data, for example, as image management data.

FIG. 7 is an explanatory diagram showing a state in which the image attribute information of the header of FIG. 5 is stored in a file separate from the image data.

The header information 5 in FIG. 5 is sent by the image management unit 12 in FIG.
The image attribute information in 0 is recorded in various types of management table 70 and managed.

The storage location of the management table 70 may be the memory within the image processing device 1 in FIG. 1 or the external storage device 5.

The management table 70 includes a number column 71 indicating a number for identifying each image, an origin column 72 indicating the cutting origin of each image,
Consists of a size field 73 that shows the cropping size of each image, a ratio field 74 that shows the magnification of each image, a file field 75 that shows the file number in which each image data is stored, and an original picture number field 76 that shows the original picture that is the cutting source. has been done.

In this way, the contents of the management table 70 that expresses image attribute information in a tabular format are as follows for each image (image numbers rlOJ to r16
J), all of the header information in Figure 5,
Or, it may be the same as a part of it.

Furthermore, corresponding to each image data, image attribute information of this management table 70 and header information 50 of FIG.
If you have duplicate image attribute information, it becomes possible to perform an efficient search when referring to an image, for example, when referring to another partial image that has the same original image as a certain partial image. . At the same time, even if management information is lost,
Information is never completely lost.

Also, if you want to use each original image or partial image independently,
Some of the attribute information is not required, so when performing composition processing, display, etc., it is necessary to instruct the program that executes it how to handle each attribute. When creating a program, if it is an independent program, it can be processed and displayed in any mode by passing it as a command parameter when starting the program.

As described above using FIGS. 1 to 7, according to this embodiment, when generating a new image that involves geometric changes such as cropping, enlarging, or reducing an image, Information attached to the generated image, that is, as attributes, information for identifying the original image, information for geometrical modification, etc. is recorded.

This makes it possible to know the relative relationship between multiple images without a special management mechanism such as a database, and to perform processing and display based on that relationship.

Furthermore, this attribute information can be managed more efficiently by associating the attribute information recorded in the header information of the image data with the image data in a table.

Of course, if a database or a corresponding search mechanism is subsequently constructed, this attribute information can be transferred to the database as is and used using the database.

[Effects of the Invention] According to the present invention, divided image data can be managed in relation to each other, componentization of image data can be realized, and operations such as image processing and display processing can be facilitated. , it becomes possible to improve the performance of the image processing device.

An image input device that reads an image and converts it into image data is connected to an image display device that displays the image data as an image, processes the image data inputted by the image input device, and displays the processing results as described above. An image processing device outputting to an image display device calculates the coordinate values of the origin of the coordinate system of each of the plurality of images on a reference coordinate system common to the plurality of images as image data of each of the plurality of images. and a coordinate transformation parameter having at least one of a parameter indicating the size of each image in the reference coordinate system and a ratio between the coordinate system of the image and the reference coordinate system. A coordinate transformation parameter setting means set corresponding to image data of each of a plurality of images, and image attribute information consisting of coordinate values and coordinate transformation parameters set by the coordinate transformation parameter setting means and the origin setting means, as described above. image management means that manages each image data in association with the image data; and image attribute information that reads the image attribute information managed by the image management means and extracts the image data based on the read image attribute information. An image processing device comprising: a reading means.
