Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an image information editing device that performs editing such as extraction, insertion, and deletion of image information in an image information processing device having, for example, an image information storage and retrieval function and an image information soft copy function.

Generally, in two manuscripts A and B, manuscript A
The following two methods can be considered to create one document by combining the predetermined portion a of the document B and the predetermined portion b of the document B, respectively. That is, in the first method, originals A and B are respectively copied using a copying machine to obtain copies A' and B'. A necessary portion a of copy A' and a necessary portion b of copy B' are cut out, pasted on a blank sheet of paper, and then copied again. As a result, necessary portions of two documents can be combined into one document. The second method is performed using a word processor when the manuscripts A and B are composed only of sentences. In other words,
Save manuscripts A and B to floppy disk as file A,
Store it as a file B, read a predetermined portion a of the file A and a predetermined portion b of the file B into a random access memory in a word processor, and edit this to create a new file;
By printing this using a printer, etc.,
Necessary portions of the two manuscripts A and B can be made into one manuscript.

However, in the first method, the original is copied and the necessary parts are cut out, which results in an increase in unnecessary parts, that is, waste, and operations such as cutting out and pasting are troublesome for the operator. Furthermore, in the second method, only characters can be handled as a manuscript, and complex figures and the like cannot be edited.

This invention was made in view of the above circumstances,
The purpose is to provide an image information editing device that can easily edit image information such as extracting, inserting, moving, or deleting image information without cutting and pasting.

An embodiment of the present invention will be described below with reference to the drawings.

1 and 2, reference numeral 1 denotes an input device, which, as shown in FIG. 3, is composed of an image information display section ₁₁ and a keyboard ₁₂ . The image information display section ₁₁ displays pixel information like a graphic display, and also displays characters, for example [2000 x 3000].
It has a bit dot structure. Image information is displayed on the screen 1a of the image information display section ₁₁ , and a cursor 30 for indicating an editing area,
A moving cursor 31 or a moving cursor 32 indicating the moving position of the editing area is displayed. The keyboard ₁₂ is used to enter a storage command and an index code representing the name of the image information to be stored when storing image information, and to input a search command and necessary information when retrieving and reproducing the stored image information. This is for inputting the index code of the image information to be displayed. In addition, the keyboard ₁₂ is used to enter a soft copy command and an index code of necessary image information when obtaining a soft copy of stored image information, and when editing, an editing command corresponding to the editing is input. It is used to input extraction commands, insertion commands, deletion commands, etc. Signals from the keyboard 1 ₂ are supplied to the main controller 2 . The main controller 2 performs editing processes such as recording, reproducing, adding, inserting, and deleting image information and index information in response to output signals from the keyboard ₁₂ . On the other hand, the image information 3 is two-dimensionally optically scanned and photoelectrically converted by a two-dimensional scanning device 4, and this photoelectrically converted image information (video signal) is sent to a recording device 5 via a main controller 2. Alternatively, it is supplied to the magnetic tape device 6. The recording device 5 receives image information from the two-dimensional scanning device 4 or reproduced image information from the magnetic tape device 6, converts it into a two-dimensional visible image, and outputs it as a hard copy 7.

FIG. 4 schematically shows the cassette tape and its feeding mechanism of the magnetic tape device 6. A fixed reel 22 that does not rotate is provided in the case 21, and this reel 22 has a width of, for example, 1. /
A magnetic tape 23 having a diameter of 2 inches (approximately 12.7 m/m) and a length of approximately 36 m is endlessly wound. When the cassette tape configured as described above is loaded, the tape 23 wound around the reel 22
The tape at the innermost circumference is pulled out through the window 22a provided in the reel 22, and fed at high speed (approximately 5 m/sec) in the direction of arrow a in the figure by the capstan 24 and pinch roller 25. 2
It is designed to be rewound to the outermost periphery of No. 3.
Therefore, the tape 23 rotates once in about 7.2 seconds. As shown in FIG. 5, one rotation of the tape 23 is confirmed by optically detecting a tape mark 26 made of silver paper or the like affixed to the connecting portion 23a of the tape 23 with a mark detector 27. ing. The output signal of the detector 27 is also used as a reference for detecting the position of a block on the tape 23 (described later). As shown in FIG.
Recording tracks 28 for the book (track width approximately 40 .mu.m, inter-track pitch approximately 52 .mu.m) are set.
Here, the recording tracks 28 are sequentially assigned track numbers "0, 1, 2, ... 198, 199" starting from the lowest track, and the two tracks located approximately in the center (track numbers "99, 199") 100", track number "99" is a spare track) is unique index information (consisting of an index code and a recording address, and the recording address consists of a track number and a block number) corresponding to one unit of image information. ) is recorded on the index recording track 28.
_1. The remaining 198 tracks (track numbers 0-98, 101-
199'') serves as an information recording track ₂₈₂ for recording image information. In addition, each recording track 28
As shown in FIG. 5, the tape is divided into 256 blocks in the longitudinal direction, and each block is marked with "0, 1,
2,...254,255'' are assigned block numbers. In order to record or reproduce information signals on the tape 23, a recording/reproducing head (a two-gap magnetic head with an erasing function) 29 provided near the capstan 24 is moved in the running direction a by a head access mechanism (not shown). orthogonal direction b
This is done by reciprocating in micron units and selecting an arbitrary recording track 28.

FIG. 6 shows the recording format of the index recording track _281. For example, for 256 blocks, data is recorded every 3 blocks from the 4th block, that is, the 4th, 7th, 10th, 13th, . . . Index information is recorded in each eye,
These are the first frame 1F, the second frame 2F,
They will be referred to as a third frame 3F, a fourth frame 4F, and so on. Thus, each frame consists of a frame start code EOL, 256 items IT from 1st to 256th, horizontal parity check code VP, recording gap GAP, and frame end code EOF. Each item also has an index code IDC consisting of alphanumeric symbols of up to 16 characters, a track number TNO in which image information with this index code name is recorded,
and the first block number BNO in which this image information is recorded. Therefore, in this embodiment, 256 pieces of index information constitute one unit of index information group, and these are recorded in one frame. The alphanumeric symbols in the above index code are a 7 unit code and a 1 unit code.
The track number and block number each consist of a 7-bit code and a 1-bit vertical parity check code. In this index recording track ₂₈₁ , index information with exactly the same content is recorded a plurality of times in order to shorten the search time for index information and eliminate the influence of dropout. For example, as shown in FIG.
recorded times. In the case of FIG. 7, the same index information is recorded for each of FD1 to FD4, with FD1 starting from the 1st frame, FD2 starting from the 22nd frame, FD3 starting from the 43rd frame, and FD4 starting from the 64th frame. Here, FD1 to FD4 are referred to as a file information group consisting of all index information for image information that can be recorded on one tape 23, respectively.

Now, how image information is stored and retrieved will be explained in more detail using FIGS. 1 and 2. First, to explain the storage of image information, when a storage command and an index code of up to 16 digits representing the name of the image information to be stored are entered from the keyboard ₁₂ , the
CPU (Central Processing Unit) 8
operates the two-dimensional scanning device 4 and the magnetic tape device 6. The two-dimensional scanning device 4 two-dimensionally scans the set image information 3 such as a document using a laser beam and photoelectrically converts it. This photoelectrically converted image information is stored in the line buffer 10 via the selector ₉₁ for each scanning line. At this time, if one unit (one page) of image information is stored as it is, a very large capacity storage circuit is required.
However, since image information often contains a great deal of redundancy, it is advantageous to store it compressed (less redundant). Therefore, in this embodiment, by supplying the line information stored in the line buffer 10 to the signal compression circuit 11 via the selector ₉₂ , the well-known
Bandwidth compression is performed by MH (Modified Hoffman) conversion, and the compressed line information is supplied to the page buffer 12 via the selector ₉₃ and stored sequentially. When all the image information for one unit is stored in the page buffer 12, the CPU 8 selects the information recording track 28 to record new image information.
₂ , and then supplies the image information in the page buffer 12 to the magnetic tape device 6, that is, the head 29, via the selector ₉₄ for each scanning line, so that the specified block, that is, the image that has already been Recording of the new image information begins in the block two blocks after the block in which the information is recorded. In order to determine from which block of which information recording track new image information should be recorded, immediately after the tape 23 of the magnetic tape device 6 starts running, the head 29 plays back the index recording track ₂₈₁ .
The recording start index information, that is, the index code, added after the last index information recorded on the index recording track ₂₈₁ .
Detects the track number TNO and block number BNO in the last item IT in which a special code (other than alphanumeric symbols) unique to the IDC section is recorded, and stores them in the index search memory RAM (random access memory) 13. This is possible by storing the .

Next, the search and reproduction output of the image information recorded and stored as described above will be explained.
Now, when a search command and an index code for necessary image information are input from the keyboard ₁₂ , the CPU 8 runs the tape 23, positions the head 29 on the index recording track ₂₈₁ , and plays back that track _281. Start.
For example, if the third block (block number 3) of the tape 23 is currently passing through the head 29, the CPU 8 issues a transfer command for one frame to the DMA (direct memory access controller) 14. give. Then, by giving a reproduction command to the recording and reproduction circuit 15, the DMA 14
The playback signal from the head 29 is accepted, and then the recording/playback circuit 15 generates a frame start code.
When EOL is detected, the DMA 14 temporarily stops the CPU 8 and outputs the playback signal accepted by the recording/playback circuit 15.
In other words, the index information group of the first frame is directly
Store it in the designated area of RAM 13. Then, when the recording/reproducing circuit 15 detects the frame end code EOF, the DMA 14 stops operating. Then
The CPU 8 searches the index information group of the first frame transferred to the RAM 13 for the index code that is the same as the index code of the required image information, starting from the first item by comparing it with the input index code. Go. At this time, if the same index code as the required index code (input index code) is found, the CPU 8 stores the track number TNO and block number BNO following this index code IDC in the RAM 13. Read from the index information group and transfer it again to the RAM 13.
is stored in the specified area. Then, the CPU 8 moves the head 29 to the information recording track ₂₈₂ corresponding to the stored track number and starts reproducing that track. At this time, the block counter is operating, so if the count matches the block number stored above, the CPU 8 transfers the playback signal from that point on, that is, the image information, to the page buffer via the recording/playback circuit 15 and the selector ₉₃ . 12. Then, when all the image information for one unit of the reproduced unit is stored in the page buffer 12, the CPU 8 converts the image information (compressed information)
By supplying the signal to the signal expansion circuit 16 for each scanning line, the band is expanded by inverse MH conversion to return to the original image information, and the information is sequentially supplied to the line buffer ₁₀ via the selector 91. The line information supplied to the line buffer 10 is sequentially supplied to the recording device 5 via the selector 9 ₂ as a serial information signal synchronized with the recording timing of the recording device 5.
Thereby, the recording device 5 outputs the reproduced image information as a hard copy 7.

Next, a soft copy of the image information recorded and archived as described above will be explained. Now, when a soft copy command and an index code for necessary image information are input from the keyboard ₁₂ , the CPU 8 runs the tape 23, positions the head 29 on the index recording track ₂₈₁ , and records the data on that track ₂₈₁ . Start playing.
In this case, the operation is similar to the search for image information, and if the same index code as the required index code is found, the CPU 8 searches the track number following this index code IDC.
Read TNO and block number BNO from the index information group in RAM 13 and read it again.
Store it in the designated area of RAM 13. And CPU8
Then, the head 29 is moved to the information recording track ₂₈₂ corresponding to the stored track number, and reproduction of that track is started. At this time, the block counter is operating, so if the count matches the block number stored above,
The CPU 8 stores the reproduced signal from that point, that is, the image information, in the page buffer 12 via the recording/reproducing circuit 15 and the selector ₉₃ . Then, when all the reproduced image information for one unit is stored in the page buffer 12, the CPU 8 supplies the image information (compressed information) to the signal expansion circuit 16 for each scanning line, thereby increasing the bandwidth by MH inverse conversion. Decompress to return to the original image information, and select selector 9
₁ to the line buffer 10.
The line information supplied to the line buffer 10 is
The data is sequentially supplied to the pixel information storage unit 17 via the selector 9 ₂ . This pixel information storage section (image information storage section) 17 stores one page's worth of supplied image information as pixel information. The output of the pixel information storage section 17 is supplied to the image information display section 1 ₁ , so that the image information display section 1 ₁ displays the image information as a soft copy.

In a device having such various functions, editing of image information recorded on the magnetic tape device 6 will be explained. First, image information A as shown in FIG. 8a is displayed on the image information display section ₁₁ using the image information soft copy function as described above.
Then, when the positions of the cursors 30 and 31 indicating the editing area are input from the keyboard 1 ₂ , the data is stored in the cursor controller 18 . The output of this cursor controller 18 is supplied to the image information display section ₁₁ via the selector ₉₆ ,
Here, the cursors 30 and 31 are displayed. When an editing area extraction command is input from the keyboard ₁₂ , the CPU 8 reads the extraction command and the address of the pixel information storage unit 17 corresponding to the editing area a according to the contents of the cursor controller 18.
Instructs the DMA 14. This results in
The DMA 14 clears image information other than the address corresponding to the editing area a in the pixel information storage section 17. Then, image information A' only for the address corresponding to the editing area a remains in the pixel information storage section 17, and is supplied to the image information display section ₁₁ via the selectors ₉₅ and ₉₆ , where it is displayed in the eighth As shown in FIG. b, an extracted edit area a is displayed.
Next, when the position of the moving cursor 32 that instructs the movement of the editing area a is input from the keyboard ₁₂ , the data is transferred to the cursor controller 18.
is memorized. The output of this cursor controller 18 is supplied via the selector ₉₆ to the image information display section ₁₁ , where it is displayed. Then, when a movement command for the editing area a is input from the keyboard 1, the CPU 8 instructs the DMA 14 about the movement command and the address of the pixel information storage section 17 corresponding to the movement position according to the contents of the cursor controller 18. Thereby, the DMA 14 transfers the pixel information at the address corresponding to the editing area a in the pixel information storage section 17 to the address corresponding to the movement position. When this transfer is completed, the pixel information storage section 17 stores the image information A'' in which the editing area a has been moved, and the image information display section ₁₁ stores the image information A'' in which the editing area a has been moved as shown in FIG. 8c. cursor 3
The item moved to the position corresponding to 2 is displayed.
Thereafter, when a command to save the image information A'' is input from the keyboard ₁₂ , the contents of the pixel information storage section 17 are stored in the selectors ₉₁ , ₉₂ , ₉₃ , ₉₃ , line buffer 1.
0, signal compression circuit 11 and page buffer 12
The data is supplied to the magnetic tape device 6 via the magnetic tape device 6, and written to a spare track of the magnetic tape device 6. At this time, an index code corresponding to the image information A'' is also written at the same time.

Next, image information B as shown in FIG. 8d is displayed on the image information display section ₁₁ by the soft copy function. Then, when the cursor position indicating editing area b is input from the keyboard 1 ₂ and an extraction command for editing area b is input, the image information is extracted from editing area b by operating in the same manner as above.
B' is stored in the pixel information storage section 17, and as shown in FIG.
An extracted editing area b as shown in is displayed on the image information display section ₁₁ . After that, if you input the storage command for image information B' from keyboard 1 ₂ ,
The contents and index of the pixel information storage section 17 at this time are recorded on the spare track of the magnetic tape device 6.

Next, when a character input command is input from the keyboard ₁₂ and "TITLE" is input as a predetermined character, that character code is stored in the refresh memory 19.
is memorized. The output of this refresh memory 19 is supplied to a character pattern generating section 20. The character pattern generating section 20 decomposes the supplied character code into character patterns, and generates a signal for each column or row of the character pattern. The output of this character pattern generation section 20 is supplied to the image information display section ₁₁ via selectors ₉₅ and ₉₆ , where "TITLE" is displayed as shown in FIG. 8f.
is displayed.

In this state, when an insertion command and the index code of image information B' are input from the keyboard ₁₂ , the image information B' corresponding to the index code is stored in the backup of the magnetic tape device 6, as in the above search. The pixel information is read out from the track and supplied to the pixel information storage section 17. The image information B' stored in the pixel information storage section 17 is sent to the line buffer ₁₀ via the selector 91 line by line.
supplied to 1 of the character code stored in the refresh memory 19 at the same time.
Character patterns for each row or column are supplied from the character pattern generating section 20 to the line buffer ₁₀ via the selector 91. As a result, the line buffer 10 stores information obtained by calculating the logical sum of the supplied image information B' and the supplied character pattern. As a result, the image information C obtained by editing the image information B' and the character pattern is stored in the pixel information storage section 17 as shown in FIG. 9c.

Then, when the insertion command and the index code of the image information A'' are input again from the keyboard ₁₂ , the image information A'' corresponding to the index code is read from the spare track of the magnetic tape device 6 in the same manner as above. and is supplied to the page buffer 12. The image information stored in the page buffer 12 is supplied line by line to the line buffer ₁₀ via the signal expansion circuit 16 and selector 91. At this time, the image information C stored in the pixel information storage section 17 is also supplied line by line to the line buffer ₁₀ via the selector 91. As a result, the line buffer 10 receives image information supplied from the page buffer 12.
Information obtained by calculating the logical sum of A'' and pixel information C supplied from the pixel information storage section 17 is stored.As a result, the image information A'' is stored in the pixel information storage section 17 as shown in FIG. 9e. The image information D obtained by editing the image information C and the image information C is stored. Thereafter, the image information stored in the pixel information storage section 17 is hard-copied by the recording device 5.

In this way, by taking the logical sum of the information from the keyboard and the image information from the image information storage section, or by taking the logical sum of the image information from the pixel information storage section and the image information from the page buffer. Since edited image information is obtained, text can be added to the image information, and editing such as deletion and addition can be easily performed on a predetermined format.

In the above embodiment, the selector outputs the OR information of the output of the first reading means and the output of the second reading means, but in this selector, the output of the first reading means and the output of the second reading means are The outputs of the reading means may be switched over time.

As described in detail above, according to the present invention, the image information stored in the storage means together with the image information read by the reading means and the index information is retrieved and reproduced and displayed on the display means, and the displayed image information The extracted and moved predetermined areas can be selectively used and synthesized, and the image information subjected to the synthesis processing can be stored in a storage means together with index information corresponding to this image information. Therefore, the image information read from the reading means and the image information retrieved and reproduced from the storage means can be combined and edited. Furthermore, since the edited image information is stored in the storage means together with the index information, the edited image information stored in the storage means is retrieved and reproduced, and the image information read from the reading means is further combined with the image information read by the reading means. It is possible to perform re-editing processing such as compositing processing, and it is possible to provide an extremely practical image information editing device.
