Field of the Invention [0002] The present invention relates to an information processing apparatus and a control method therefor, and more particularly, to an information processing apparatus for editing a document composed of images, character codes, etc. It is about the method. 2. Description of the Related Art There has been a remarkable development in image editing apparatuses in recent years. In particular, in image data input from an image reading device or an external storage device, and editing work on the input image data, a desired image can be formed by a simple operation. It has become possible. However, document data (including graphic data) and image data (image data)
Are mixed and edited independently or individually,
At present, it cannot be reflected in the output image. The present invention has been made in view of the prior art, and even if the respective document elements are close to or superimposed on each other, it is possible to surely select only a desired document element group among the document elements and to select the selected document element group. It is an object of the present invention to provide an information processing apparatus and an information processing method which make it possible to make a group of document elements into one document element. [0006] In order to solve this problem, for example, an information processing apparatus of the present invention has the following configuration. That is, storage means for storing a document composed of a plurality of document elements, display means for displaying the plurality of document elements constituting the document on a display screen, Area specifying means for specifying an area to be specified; display control means for, when an area is specified by the area specifying means, selectively displaying each document element included in the area independently of each other; An element selecting means for selecting a plurality of desired document elements from among the displayed document elements, and managing the plurality of document elements selected by the element selecting means as one document element in accordance with a predetermined instruction Management means for performing the operation. An embodiment according to the present invention will be described below in detail with reference to the accompanying drawings. <Description of Outline of Configuration (FIG. 1)> FIG. 1 shows an outline of a block of a document image editing apparatus according to the present embodiment. In FIG. 1, reference numeral 1 denotes a CPU for controlling the entire apparatus, and a program (FIGS. 7 to 1) stored in a ROM 1a.
0), and the RAM 1b is used for the work area. Reference numeral 2 denotes a system RAM which temporarily stores various data. Reference numeral 3 denotes an image conversion unit, which moves, rotates, and scales the image. Reference numeral 4 denotes a compander for expanding the compressed image data or compressing the image data. 5 is an image memory for expanding image data, 6 is a document memory for expanding text information (code information), and 7 is a character generator (CG) which receives code information in the document memory 6 and generates a character / symbol pattern. ) And 8 are VRAMs corresponding to the display screen of the display unit 9 and developing image data. Reference numeral 10 denotes a printer reader I / F (interface), which includes an image reading device 11 and a printer 12.
The input and output of data to and from is performed via this I / F 10. Further, the RS-232CI / F 13 is an interface for data communication with the outside. 14 is a keyboard,
Reference numeral 15 denotes a mouse, and data input from these input devices is taken in via a keyboard / mouse controller 19. Hereinafter, reference numeral 17 denotes an external memory (for example, a magnetic disk or the like), which stores and reads data via the I / F 16. Reference numeral 18 denotes a memory management unit that manages various memories. <Explanation of File Configuration (FIG. 2)> An outline of the operation of the document image processing apparatus according to the embodiment having the above configuration will be described below. A plurality of document image files are stored in the magnetic disk 17 described above, and information of one page of each document image file has a structure as shown in FIG. However, here, the image data is 2
Also, text (consisting of character code) data will be described as two, and this information is read from the magnetic disk 17 and temporarily stored in the system RAM 2. The number of text data and image data is not limited to this, and may be any number. As shown in the figure, one page of document image information has file attribute identification information 26, which is a type of each data, an attribute identifier representing page data, a document management data identifier, a binder management identifier, and a cabinet management identifier. Etc. are included. Here, it is assumed that a set of pages is a document, a set of documents is a binder, and a set of binders is a cabinet. Also, page management data 2
7 stores the chain information of the page information, that is, an identifier indicating whether or not there is a next page, or in addition, an identifier indicating the page number of the page. The search data 28 stores a keyword for searching for information on this page. Paper attribute 2
Reference numeral 9 stores the size of the printing paper when outputting and information on its output direction. The images 22 and 23 are compressed and stored in the image data 30 and 31, and are obtained by being expanded by the compander 4. The image data 30 and 31 also store information on the display position on the display screen (that is, the development position on the VRAM 8). 32 and 33 are code data.
As shown in 4 'and 25', character code groups ("the star knows anything." And "the drop of the moon is a girl's tear."), Line spacing (line pitch, etc.), character size, display position, Information about the display direction (vertical writing or horizontal writing, etc.) is stored.
The display examples are shown at 24 and 25 in the figure. Incidentally, 22 in the figure
A frame indicated by a solid line of ~ 25 indicates a display screen of the display unit 9. <Description of Processing Outline (FIGS. 3 to 6)> As described above, one page of information read from the magnetic disk 17 is temporarily stored in the system RAM 2, but the code (text) data 32 and 33 are stored in the document memory 6 and converted into a font pattern by the CG 7 and then expanded in the VRAM 8 in the set position, size and direction. On the other hand, since the image data 30 and 31 are data in a compressed state, they are decoded by the companding unit 4 and are expanded in the image memory 5 and are expanded in the set positions of the VRAM 8. FIG. 3 shows a state where the data is developed in the VRAM 8 at this time, and FIG. Also, the read file and the image memory 5,
FIG. 6 shows the relationship between the document memory and its VRAM. still,
The dashed line in FIG. 3 is for clarifying the area of the image data, and is not actually developed. The operator executes various editing processes while looking at this display screen. In the embodiment, it is assumed that the operator performs various editing processes mainly with the graphic cursor 53 linked with the mouse 15. In FIG. 4, reference numeral 54 denotes an area for selecting various editing processes, and reference numeral 55 denotes an area for designating an editing target. These areas 54,
When specifying 55, the graphic cursor 53 is moved to a desired position and selected by pressing a mouse button. Now, if an image and a sentence are mixedly displayed, it is naturally necessary to perform processing such as moving or rotating only the image or the sentence. Therefore, in the following description, the replacement process will be described first. The editing process such as the replacement process in the embodiment has three modes, including image replacement, character replacement, and image / character replacement. I. Image Replacement Process This mode is a mode in which two areas are specified and only images (graphics) in each area are replaced (exchanged). In the embodiment, first, the “graphic (image)” of the area 55 is designated by the graphic cursor 53, and it is set that the graphic is only the graphic. Similarly, to specify the edit mode,
4. Select "Replace". Note that each of the selected specification columns is displayed in reverse video to notify the operator that the specification has been correctly made. When the above operation is completed, an area including a figure to be replaced is set. In this embodiment, one area "moon pattern" to be replaced is rectangular as shown in FIG. In order to set an area, both ends of the diagonal line are designated with a graphic cursor. Next, an area including the “star pattern” of the destination to be replaced is set by the same operation. When this operation is completed or when a predetermined key or mouse button is pressed, the processing from the image 61 to the image 62 in FIG. 5 is achieved. In the specific processing contents, since the development position in the set area changes, the development position information in the image data 30, 31 described above is rewritten to the newly set position information image. , Again according to that information V
This is achieved by executing a process of expanding the data in the RAM. Accordingly, when the image 62 is generated and stored on the magnetic disk 17, data obtained by compressing each image by the companding unit 4 and newly updated development position information are stored in the image data 30.
31 is stored. II. Character replacement processing In this mode, only the text (characters) in the two set areas is replaced, and the operation is performed in place of specifying the “graphic (image)” in the area 55 in the above-described image replacement processing. All you have to do is specify "characters". Accordingly, the content of the operation is omitted, but after the processing by the operation, the image 63 is as shown in FIG. That is, the characters "month" and "star" are replaced. When the image 63 is generated and stored, the updated character position information is stored in the code data 32 and 33 and stored on the magnetic disk 17. III. Image / character replacement processing This mode refers to a mode in which image replacement processing and character replacement processing are simultaneously performed.
This is achieved by selecting 5 “graphics (image) / character”. The replacement result at this time is shown in an image 64. As described above, the information in each of the data 30 to 33 in the storage processing is stored in an updated state. With the above-described processing, it is possible to replace only the image or only the character, or to replace both of them. still,
Although only the replacement process has been described here, other processes,
In other words, the movement, deletion, rotation, and enlargement processing can be performed in exactly the same manner. The content of “layer editing” in the area 55 will be described later. <Explanation of Edit Processing Procedure> The above-described processing will be described below with reference to the flowcharts of FIGS. First, in step S1, the magnetic disk 17
The information of one page is read into the system RAM 2. Next, the process proceeds to step S2, where the image data in the read information is converted into an image by the companding unit 4, developed in the image memory 5, and developed at the set position in the VRAM 8. The code data is expanded in the document memory 6 and converted into a character pattern by the CG 7, and then expanded and displayed in the VRAM 8. In step S3, information for designating the work from the operator is input. Based on the information, the process branches to each process in step S4. When the processing for both the graphic and the character is selected, the processing proceeds to step S5, where information relating to various editing processing such as replacement processing is input. Next, in step S6, based on the input information, the areas input to the image memory 5 and the document memory 6 and the editing contents (edit types) are sequentially read from the system RAM.
2 (hereinafter, this area is referred to as a buffer). In the next step S7, the edited result is expanded again in the VRAM 8, and the result is reflected. In the next step S8, it is determined whether or not the editing processing has been completed. When further editing processing is to be executed, the flow returns to step S3 to execute the same processing. If data indicating the end of the editing operation has been input, the process proceeds to step S9 to determine whether or not to save the edited content. If the user wants to save the data, the user inputs the data to that effect and executes the saving process in step S11. If not, the process proceeds to step S10.
To clear the data in the buffer. In step S11, the contents of the image memory 5 and the document memory 6 are changed according to the data stored in the buffer. In step S12, a new data file is created and stored in the magnetic disk device 17. . On the other hand, if it is determined in step S4 that the object to be edited is a figure only, the processing of step S13 and subsequent steps (FIG. 8) is performed.
Steps 21 and 21 (FIG. 9) are executed, but the details of the processing in steps S13 to S20 and steps S21 to S28 are omitted because they are the same as those in steps S5 to S12 described above. <Description of Image and Document Registration Process (FIG. 1)
0)> Up to the above, the editing processing procedure has mainly been described, but a case where a new file is created can naturally be considered. The registration process will be described below. First, in step S31, it is determined whether or not a new file is to be created. If this determination is YES, the next step S2 is not performed and the direct step S31 is performed.
Move to 33. "NO", that is, when editing an existing file, the file is read from the magnetic disk 17 in step S32, and the process of expanding the file into each memory is executed. In step S33, it is determined whether the information to be registered is an image or a code (character). If it is image data, the process proceeds to step S34, where an image is read by the image reading device 11, and the image data is stored in the image memory 5 in step S35, and is developed and displayed in the VRAM 8 in step S36. Then, step S37
To execute various editing processes (change of development position, etc.). On the other hand, if it is determined that the registration target is a code, that is, text information, the process proceeds to step S38 and the keyboard 1
4 and the like, and constructs the character code in the document memory 6. At the same time, the character code expanded in the document memory 6 is converted into a character pattern by the CG 7 and then sequentially expanded in the VRAM 8 (step S39). Thereafter, the process proceeds to step S40 to perform various document editing processes (decompression position, character size, development direction, etc.).
Will be executed. Now, input / edit of figures and creation / creation of documents
When the editing is completed, it is next determined whether or not to execute the registration process at this time. If there is further information to be registered, the process from step S33 is executed. However, at this time, it is registered as information separate from the figure or document previously input / edited. That is, when the file is saved, the image data 30, 31 or the code data 3
These pieces of information are treated differently as in 2,33. When the input of the information to be registered is completed, the process proceeds to step S42 to determine whether or not to newly save the information. In the case of new storage, a file for storage is newly created in the magnetic disk 17 in step S44, but if not, the existing file is updated according to the input information in step S43. [Description of Second Embodiment (FIGS. 11 to 1)
6)] In the above-described embodiment, a description has been given of the processing in a case where an area is set, and one document and one image information are included in the area. However, when a plurality of documents or graphics are present in this area, It is also conceivable to try to edit only the desired image. For example, as shown in FIG. 13, a file of one page is composed of five data, that is, image data A and code data B to E (however, the code data D and E may be vector information). Next, a case where the combined display forms the image F will be described. FIG. 11 shows a state in which this file is displayed on a display screen and a document "curtain" is input. Looking at this display screen, the operator selects the area 91 shown in the figure.
Is set, and subsequently "layer editing" of the area 55 is designated, the designated area is displayed as another window 92 (FIG. 12). It should be noted that, in the case shown in the figure, a state in which the logical sum of each image is obtained is shown. However, by switching the display mode, it is also possible to display by logical product, exclusive logical sum, and store. Now, an area 900 around this window
A to E in 904 correspond to the image data A and the code data B to E in the file, and the operator selects an image to be edited. For example, when the graphic cursor 53 (which may be designated by a keyboard or the like) is selected in all of these areas 900 to 904, the object to be edited is all the images in the window 92. An editing process for rotating only the code data D and E will be described. When rotating only the image data A and the code data D and E, first, areas 900, 903 and 904 are designated in this window 92. The state at this time is shown in FIG. As shown in the figure, the selected image is displayed as a solid line, and the others are displayed as dashed lines, and the corresponding areas 900, 903, and 904 are displayed to indicate that they have been selected (reverse display). In this state, the area 54 (FIG. 1)
1) is selected and “180 °” is set as the rotation angle from a keyboard or the like.
Are displayed as shown in FIG. Actually, when these settings are made, it is achieved by performing a rotation process for each selected image. As described above, even when a plurality of images are superimposed, it is possible to edit only a necessary image from among them. When "delete" in the area 54 is specified in the state of FIG. 14, only the specified image is deleted. Further, when editing images by performing such operations, there are cases where certain images are always edited in the same state (whether or not they are selected as edit targets). For such images, it is more convenient to treat them as one synthesized image instead of separate data from the viewpoint of memory efficiency. For example, code data (vector data)
In the case of D and E, these two images are logically ORed as shown in FIG. 16 to form new code data D '. By doing so, it is possible to reduce the capacity of the file. After that, since the data can be handled as the code data D ', the operability is remarkably improved. In the setting method of this processing, an icon “combination” is prepared in the area 54 of FIG.
After selecting 3,904, the combination processing may be performed by designating "composition". As described above, according to the present embodiment,
Even when document information and image information are displayed in a mixed or superimposed manner, it is possible to perform the editing process for each piece of information. According to the second embodiment, when a plurality of image data and code data exist in a designated area, they are displayed so as to be identifiable, and a plurality of desired ones are selected. By doing so, the same editing process can be easily performed on the selected data. In particular, since a plurality of desired document elements of a plurality of document elements, such as code data, are managed as one document element, data thereafter becomes one document element. Can be selected by one operation without selecting multiple times, so that operability such as editing can be remarkably improved. As described above, according to the present invention, even if each document element is close to or superimposed, only a desired document element group among them can be reliably selected, and
It becomes possible to make the selected document element group one document element. [0050]
