Description

DETAILED DESCRIPTION OF THE INVENTION According to a word processor, sentences inputted from a keyboard can be freely edited, assembled into appropriate sentences, and outputted to a typewriter.

In contrast to the word processor that allows text to be edited freely, systems have been developed that allow graphics to be edited freely. This system is called an image handler. For example, when a manuscript like the one shown in Figure 1A is input, it changes the position and size of figures in the manuscript, adds or deletes typed characters, etc. It is possible to obtain a hard copy as shown in Figure 1B.

Therefore, this image handler is particularly effective when creating pamphlets, instruction manuals, and the like.

However, in this case, in order to obtain a hard copy as shown in FIG. 1B, for example, cut out originals 1 and 2 as shown in FIGS. The original documents 1 and 2 must be processed by creating a secondary document shown in FIG. 1A and inputting it to an image handler to obtain a hard copy shown in FIG. 1B.
However, depending on the original, such processing may not be possible, and if the processing is incorrect, it is difficult to repair.

This invention attempts to solve these problems.

Let's explain one example below.

FIG. 2 shows an example of the image handler according to the present invention. In this example, it is possible to input up to a portrait-long A4 size document, and the document can be input with 1920 dots in the horizontal direction (horizontal direction) and 1920 dots in the vertical direction (vertical direction). Direction) This is a case where processing is possible at a resolution of 2560 dots.

In Figure 2, 11 indicates 16-bit parallel processing.
A CPU, 12 a ROM in which programs for various processes including the above-mentioned editing process and a flowchart program shown in FIG. 3 are written, 13 a RAM for a work area, 14
is the system bus. Further, numeral 21 indicates an image reader for capturing an image of a document, and this is said to be similar to that used in facsimiles and the like. That is, in this example, a 1920-bit one-dimensional CCD sensor is arranged horizontally, and the document is vertically moved stepwise in front of it at a constant speed to perform vertical scanning.
The contents of the sensor are serially read out and a horizontal scan is performed. In this way, one page of the manuscript is 1920 dots x 2560
It is decomposed into dots, and the shading of the dots is sequentially read as binary data of 1 bit per dot.

Further, 22 is a keyboard having full keys for inputting letters, numbers, symbols, etc. and function keys for operating this image handler, and 23 is a joystick for controlling the coordinates of a graphic cursor.

Reference numeral 31 denotes a buffer frame memory for storing document data, and this frame memory has a capacity of 600 KB (=1920×2560 bits), which is equivalent to, for example, one document. Furthermore, 32 indicates an image memory for displaying the original on a CRT display, which has a capacity of, for example, 150 KB and has a video memory.
It is configured as a RAM, and the data in the frame memory 31 is thinned out every one dot in the horizontal and vertical directions and is supplied. Further, numeral 33 indicates a character memory, in which data such as sentences, numbers, and symbols inputted from the full keys of the keyboard 21 is stored in, for example, 8-bit ASCII code, and the data is read out for display. Therefore, the memory 33 has a capacity of, for example, 80 characters x 70 lines, and is configured as a video RAM.

Furthermore, 34 indicates a shrink circuit. This shrink circuit 34 thins out the data in the frame memory 31 in the horizontal and vertical directions and supplies it to the image memory 32 as described above, or when reducing the figure as shown in FIGS. 1A and 1B. This is a process to thin out data.

Also, 41 is a CRT display, 42 is a CRT
A controller 43 represents a character generator, a CRT display 41 is provided with a picture tube having a screen approximately the size of an A4 size sheet, and a controller 42 performs horizontal and vertical deflections.

At this time, the data in the image memory 32 is read out by the controller 42 and supplied to the display 41 as a luminance signal.
A manuscript is displayed on the display 41. moreover,
The data in the character memory 33 is also transferred to the controller 4.
2, the data is converted by the character generator 43 into a luminance signal of corresponding characters, numbers, and symbols, and this signal is supplied to the display 41. Therefore, input from the full keys of the keyboard 22 to the display 41 is performed. The displayed letters, numbers, and symbols are displayed.

Furthermore, 44 is a dot printer that outputs the edited screen as a hard copy. Further, 51 denotes a mass storage device for storing input manuscript data or edited screen data, and this is constituted by, for example, a VTR-type data recorder. 52 is a compression circuit that reduces redundancy when recording data; 53 is an encoder that encodes the recorded data for error correction; 54 is an error correction decoder; and 55 is an expansion circuit; these circuits 54,5
Reference numeral 5 serves as a pair with circuits 53 and 52 to correct errors in reproduced data and restore original data.

Also, in the flowchart of Figure 3,
[101] to [103] are the input range of the first manuscript (first
Steps to specify the area A ₁ ) surrounded by the broken line in Figure C, [111] to [115] are steps to input only the specified range A ₁ , and steps [121] to [122] are the steps to enter the second area A 1 ).
input range of the original (the area surrounded by the broken line in Figure 1 D)
A ₂ ), [131] to [134] are steps for specifying the display position when displaying the specified range A ₂ on the display 41,
[141] to [146] are steps for inputting only the specified range _A2 of the second original. In addition,
Details of each step will be described later.

Next, let's explain how this image handler works and how to use it.

When performing normal editing (editing by inputting only one document) In this case, the document is set on the image reader 21 and the function key on the keyboard 22 is operated to enter the document input mode. Then, the document is read by the reader 21, and the data is sequentially written into the frame memory 31.
Then, when the entire area of the document has been read and the data has been written to the memory 31,
The data in the memory 31 is thinned out every other dot in the horizontal and vertical directions by the shrink circuit 34, and then transferred to the image memory 32, and the transferred data is transferred from the memory 32 to the controller 42.
The data are sequentially read out and supplied to the display 41. Therefore, the document input from the reader 21 is displayed on the display 41.

Next, when the user operates the joystick 23, the cursor moves on the screen of the display 41 in response to this operation. Therefore, the user operates the joy stick 23 to select the two opposing vertices (the first
Points corresponding to points P ₁ and Q ₁ in figure C) are specified with the cursor, and if the position of the figure is changed,
The changed position is similarly specified with the cursor, and if the figure is to be reduced, the reduction ratio is specified using the full key on the keyboard 22. Then, the data in the image memory 32 is processed based on the designation, and the data in the memory 32 is transferred or thinned out, and accordingly, the position or size of the figure on the screen of the display 41 is changed. However, in this case, the data in the frame memory 31 is not changed.

In this way, the figures on the display 41 are sequentially edited to the desired position or size.

Note that if you make a mistake while editing this figure, if you operate the function key on the keyboard 22, the data in the frame memory 31 will be thinned out again by the shrink circuit 34 and supplied to the image memory 32, and therefore, You can edit it again.

Further, when a full key on the keyboard 22 is operated, the key data is sequentially written into the character memory 33, and this data is transferred to the controller 42.
The character generator 43
The luminance signal is converted into a luminance signal and supplied to the display 41. Therefore, the display 41 displays the manuscript input from the reader 31, and
Characters, numbers, and symbols entered from the keyboard 22 are also displayed. In this case, the display of images, characters, etc. can be specified using the keyboard 22, such as overlapping display, preferential display of one in the overlapping area, or preferential display of one over the entire area.

In response to the input from this keyboard 22, characters etc. can be added/added by operating the full keys.
They can be deleted freely, and their display position can be arbitrarily designated by operating the cursor keys on the keyboard 22.

After the desired image of the document is obtained on the display 41 through the above operations, the function key on the keyboard 22 is operated. Then, the data in the frame memory 31 is processed to match the image on the display 41. In other words, the same processing as that performed on the memories 32 and 33 by the operation of the joystick 23 and the keyboard 22 is performed on the memory 31. Therefore, the edited graphic data and font data of characters input from the keyboard 22 are also written in the memory 31.

After this process is completed, when the function keys on the keyboard 22 are operated, the data in the frame memory 31 is sequentially read out and sent to the printer 44.
Therefore, the edited hard copy is output to the printer 44. In this case, the data in the frame memory 31 has a density four times that of the image memory 32, so the resulting hard copy has a sufficiently high resolution. That is, the resolution on the screen of the display 41 is limited by the horizontal scanning frequency and vertical scanning frequency of the display 41 and the capacity of the image memory 32;
The actual hard copy obtained from printer 44 is high resolution.

Further, the data in the frame memory 31 is supplied to the storage device 51 through circuits 52 and 53 and recorded therein, if necessary. This recorded data is reproduced by the storage device 51 when necessary, and the circuit 5
4 and 55 to the memory 31. However, data can be output to the printer 44 and data can be accessed to the storage device 51 at any other time before or after editing.

In this way, various edits can be made to the graphics of the original.

When carrying out a special operation according to the present invention In this case, processing is performed according to the routine of the flowchart in FIG. 3, and for example, when documents 1 and 2 as shown in FIG. , the hard copy shown in FIG. 1B can be obtained through the state shown in FIG. 1A.

That is, first, in the manuscripts shown in Figure 1 C and D, it is assumed that the rectangular areas A ₁ and A ₂ surrounded by broken lines are the necessary range for editing, and that the two opposing areas of these areas A ₁ and A ₂ are The vertices are respectively points P ₁ , Q ₁ and P ₂ ,
_Q2 . Further, as shown in FIG. 1E, on the screen 41S of the display 41, areas A ₁ , A ₂ and areas corresponding to points P ₁ , Q ₁ , P ₂ , Q ₂ and point areas a ₁ , a ₂ and Points p ₁ , q ₁ , p ₂ , and q ₂ are assumed (the original and the screen 41S are approximately the same size).

The routine in Figure 3 is step [101]
Start from and proceed to step [102]. This step [102] is for specifying the input range _A1 of the first document 1, and the user
3 to move the cursor and specify points p ₁ and q ₁ corresponding to points P ₁ and Q ₁ .

When this specification is made, the process continues to step [103], and as shown in FIG. 1F (i=1)
The position x _{1 ,} y ₁ and the size _{u 1 ,} v ₁ of the area a ₁ are calculated from the data at the points p 1 and q 1 and stored in the RAM 13 .

Next, the process proceeds to step [111], where the user is requested to input the first document 1, so the user sets the document 1 on the reader 21. Then, in step [112], the document 1 is read by the reader 21.
One line corresponding to the section u ₁ of the area A ₁ of the area A ₁ is read, and the data is written to the address corresponding to the section u ₁ in the frame memory 31 in step [113]. Then, in step [114], the data written in the memory 31 in step [113] is transferred to the shrink circuit 34.
As in the case of , the data is thinned out to 1/2 and transferred to the address corresponding to the section u ₁ in the image memory 32 .

When this process is completed, it is determined in step [115] whether or not the processes in steps [112] to [114] have been performed for all rows in section v ₁ of area a ₁ . If it has not been performed, jump to step [112], and if it has been performed for all rows, proceed to step [121]. Therefore, in steps [111] to [115], only area _A1 of document 1 is
The data is read line by line and written to the address corresponding to area _A1 of the frame memory 31 and image memory 32, and when this writing is completed, the process advances to step [121].

Then, in step [121], the input range _A2 of the second original 2 is specified, and the user operates the joystick 23 to move the cursor to select the points _p2 , _Q2 corresponding to the points P2, _{Q2, and} so on. Specify q ₂ .

When this specification is made, in step [122],
As shown in FIG. 1F, the position x _{2 ,} y ₂ and the size u ₂ , v ₂ of area a 2 are calculated from the data at points p ₂ and q ₂ (i=2) and stored in the RAM 13.

The process then proceeds to step [131]. This step [131] moves area _A2 of document 2 to screen 4.
This is to specify which area and position of 1S to display. Therefore, if the display area and position are _area a ₃ and points p ₃ and q ₃ as shown by the broken line in FIG. specify. Then _, in _step [132], as shown in FIG _.
The position of point q ₃ is calculated from the data of , and in the next step [133] this point q ₃ is
It is determined whether the point _P3 does not protrude from the area S or whether the area A3 does not overlap the area _A1 . If the point _P3 is invalid, the process returns to step [131] and the point _P3 is re-inputted, making it valid. If so, proceed to step [141].

In this step [141], the user is requested to input the second original 2, so the user sets the original 2 on the reader 21. Then, step [142]
, the reader 21 scans area A ₂ of the document 2.
Among them, one line corresponding to section u ₂ of area a ₂ is read, and the data is written to the address corresponding to section u ₃ in frame memory 31 in step [143]. Then step [144]
In step [143], the data written in the memory 31 is thinned out to 1/2 as in the case of the shrink circuit 34, and the data written in the image memory 32 is
It is transferred to the address corresponding to section _u3 .

When this process is completed, it is determined in step [145] whether or not the processes in steps [142] to [144] have been performed for all rows in section v ₃ of area a ₃ . If not, jump to step [142], and if all rows have been filled, proceed to step [151]. Therefore, step [141]
~ [145] reads only area A ₂ of original 2 line by line and the data is stored in frame memory 31
and is written to the address corresponding to area _a3 of the image memory 32, and when this writing is completed,
Proceed to step [151].

In this step [151], the user is asked whether to input the next manuscript, so if the user answers this, the answer to step [151] is judged in the next step [152], and the next manuscript is input. When inputting, the program jumps to step [121], and when inputting the manuscript is finished, the program advances to step [153] to end this routine.

Therefore, at the end of this routine, the data of the figures in the areas A ₁ and A 2 of the originals 1 and ₂ are written in the frame memory 31 and the image memory 32 at the addresses corresponding to the positions shown in FIG. 1A. At the same time, the image shown in FIG. 1A is displayed on the display 41. Therefore, by performing the following processing, the hard copy shown in FIG. 1B can be obtained.

Thus, according to the present invention, it is possible to electronically cut out and input a plurality of original documents, and there is no need to cut out or mark original documents. Therefore, the original document is not damaged, and even if you make a mistake in the input range, you can easily correct it.

Furthermore, since the input range is regulated when inputting an original, the frame memory 31 only needs to have a capacity of one original, which is advantageous in terms of cost. Further, there is no need to change the hardware, and it can be easily realized by simply adding the program shown in the flowchart shown in FIG.
