Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to an image editing device used in a copying machine or the like, and particularly to an image (LVA) aggregation device that enables novel image expression.

[Conventional technology]

In recent years, instead of simply copying the original image as is, it has become possible to set and extract the area of the original image.

Copying machines that perform image processing such as deletion have been developed.

In such a copying machine capable of image editing, it is necessary to set an area to be edited during the above-mentioned image editing.

When setting this editing area, a coordinate input device called a digitizer is often used. This digitizer has a width corresponding to the width of the original, and by placing the original on the digitizer and specifying the area to be edited, the coordinate data of the editing area is imported into the copying machine. It has become. The digitizer is, for example, integrated with the platen cover of the copying machine main body, is pivotally attached to the copying machine main body, and can be opened and closed with respect to the platen glass on the top surface of the copying machine main body.

When making copies using the copying machine configured as described above, first, the platen cover is closed and the document is placed face up on it, and then editing work is performed. Next, the original is removed from the upper surface of the platen cover, the platen cover is opened, and the original is placed upside down at a predetermined position on the platen glass. Then, by closing the platen cover and pressing a copy start key provided on the main body of the copying machine, copying is performed with predetermined processing applied to the set area.

[Problem to be solved by the invention]

However, the image processing that is possible with the above-mentioned editable copying machine is limited to relatively simple processing such as extraction and deletion, and it is difficult to freely output the image that the user intends. Ta.

The present invention was devised to solve the above-mentioned problems, and an object of the present invention is to perform novel image processing that could not be achieved with conventional image editing devices.

[Means to solve the problem]

In order to achieve the above object, the image editing device of the present invention includes means for determining a straight line connecting each of the coordinates based on the coordinates of at least two points inputted by a coordinate input means, and a means corresponding to the straight line in a bitmap memory. an image input device that scans a document to read the document image; and a device that reads the contents of the bit map memory in synchronization with scanning by the image input device;
The present invention is characterized by providing means for replacing the information of the original image with specific data or adding the specific data to the information of the original image when the specific bit is read out from the bitmap memory. shall be.

It is desirable to provide means for changing the width and/or the number of linear bit patterns corresponding to the straight line as necessary.

[Effect]

In the present invention, writing to the bitmap memory is performed in a pattern corresponding to a straight line connecting a plurality of points specified by the coordinate input means. Then, when the original image is scanned, the contents of the bitmap memory are read in synchronization with this, and when the pattern is detected, a red image, for example, is output superimposed on the original image. As a result, an output image in which red straight lines, rectangular frames, etc. are superimposed on the original image is obtained.

In the color copying machine of this embodiment, a copying machine main body 2 includes a color image input section 1 for inputting an image of a document, and a color image output section (not shown) for outputting an image. An editing instruction device 3 is attached to the color image input section 1 of the copying machine main body 2 so as to be openable and closable.

In the color image input unit 1, an original (not shown) placed on a platen glass 10 is illuminated by red, green, and blue light sources 11.

The scanning section A consists of 11G, IIB and mirror 12.
It is movable in the left-right direction by a scanner motor (not shown) in the range from the position shown by the solid line to the position shown by the dashed-dotted line in the figure. The image sensor 14 reads the image of the original in the sub-scanning direction, that is, in the horizontal direction of the drawing, while reading one line of the image in the main scanning direction of the original, that is, in the direction perpendicular to the drawing. Red and green thus obtained.

The blue color signal is supplied to a color image output section provided in the main body 2 of the copying machine.

In the color image output section, the signals are converted into yellow, magenta, cyan, and black color material signals in the signal processing circuit section 92, and then sent to the recording section 23Y for each color material.

It is supplied to 23M, 23C, and 23K.

The recording paper in the lower tray 81a or the upper tray 81b is carried into the machine by a carry-in roller 82, and is sent to the yellow recording section 2'3Y direction. In the yellow recording section 23Y, the ink donor film 86 from the supply roll 84 and the recording paper from the trays 81a and 81b are sandwiched between the thermal head 83 and the platen roller 85, and the thermal head 83 is used to record the yellow color. By driving with the material signal, the ink of the ink donor film 86 is transferred to the recording paper to form a yellow image on the recording paper. After the transfer, the recording paper and the ink donor film 86 are separated,
The recording paper is sent to the next magenta recording section 23M, and the ink donor film 86 is wound up by a winding roll 87. Note that the magenta, cyan, and black recording sections 23M, 23C, and 23K described below also have the same structure as the yellow recording section 23Y, so the explanation of each member will be omitted.

In the magenta recording section 23M, the same operation as described above is performed, and a magenta image is transferred onto the yellow image.

In the figure, numeral 91 indicates a paper path switching claw for switching between color copying and black-and-white copying, and the figure shows the orientation during color copying. When making a black-and-white copy, the paper path switching claw 91 rotates slightly clockwise in the figure, and the recording paper from the upper tray 81b is scooped upward by the paper path switching claw 91 and directly transferred to black recording by the conveyance roller 93. The ink is sent to section 23K, and transfer is performed using only the black ink donor film. Therefore, the color image output section 2
The conveyance path for the recording paper in the printer is shortened, and the time required for copying can be shortened. Note that 94 is a power supply section that supplies operating voltage to each section. Further, S1 to S are paper sensors, which are used for detecting paper jams and the like.

Next, details of the editing control circuit 30 and the image processing circuit 48 will be explained with reference to FIG. 7.

A digitizer 61 provided in the editing instruction device 3 is connected to a CPU 6 for controlling editing via a digitizer control circuit 62.
3, and when area designation area E (see Figure 4) is pressed on the editing instruction device 3, the CP
U63 processes coordinate data as area information, and when function designation area E is pressed, coordinate data is processed as function information.

The editing control CPU 63 is connected to a host CPU (not shown) on the main body side via a host Ilo (input/output device) 64. In addition, the CPU 63 uses the latch 65
and is connected to a drawing device generally called a CRTC (cathode ray control circuit) 67 via a gate 66;
A bitmap memory 68 is connected to the TC 67. The CRT C67 uses the bitmap memory 68 based on the coordinate data and drawing commands from the CPU 63.
In order to quickly fill in closed areas, DM
A (direct memory access) transfer is used to read data from the bitmap memory 68 at high speed; for example, LSI (large scale integrated circuit) HD63484 manufactured by Hitachi, Ltd. is used. In addition,
Filling a closed area refers to an operation in which a bit in the bitmap memory 68 corresponding to an area defined by a plurality of specified coordinates is set to, for example, rN.

Also connected to the CPU 63 is a RAM 69 for storing coordinate data input from the digitizer 61 and a function number indicating the type of processing. Furthermore, the CPU 63 and CRT C67 have a game) 70.
RAM table 72 and registered color RAM M7 via 71
Connected to 3. In the RAM table 72, the correspondence between the function number and the function code for performing actual processing is written, and the registered color RAM
3, the correspondence between the color code and the color registered by the user is written.

An example of the configuration of the RAM table 72 is shown in Table 1.

Note that the subscript H of the function code means that it is expressed in hexadecimal.

During the first surface image processing, the contents of the bitmap memory 68 are
The RAM table 72 is read out by the RT C67, and accessed by the synchronization circuit 74 in synchronization with scanning of the original.
A function code corresponding to the function number is read from the RAM table 72.

This function code is supplied to the data processing circuit 75, which processes the image signal from the dither processing circuit 1 (see FIG. 6) based on the function code.

Note that 76 is a standard color ROM in which data of predetermined standard colors is stored, and when the user specifies the use of a bleaching color, the data is read out from the standard color ROM 76 instead of from the registered color RAM M73. is performed and image processing is performed.

The data processing circuit 75 is composed of, for example, a look-up table type ROM, and when the function codes roO, J corresponding to no processing are input,
The image data is passed through as is, when the function code "80□" corresponding to deletion is input, all image data output is cut off, and when the function code rC3,, J corresponding to coloring red is input, , a signal corresponding to red is superimposed on the image data and output.

The above process, that is, reads the data in the bitmap memory at the corresponding location while scanning the image of the document,
By comparing image data and memory data for each pixel, that is, for each bit, and performing predetermined processing based on the comparison result, predetermined image processing is performed on the area instructed by the editing instruction device 3. be able to.

In this embodiment, various image processing can be performed using the above-described circuit.

For example, you may want to emphasize characters in a manuscript by underlining them. Here, an example will be described in which a red underline is drawn on the row of characters rABCDJ in a document as shown in FIG. 8(a) to obtain a copy as shown in FIG. 8(b).

First, as shown in FIG. 3, the editing instruction device 3 of the copying machine is closed, and the original to be edited is placed on the editing instruction input surface 31 with the image side of the original facing upward.

At this time, positioning is performed by abutting the lower right of the document against the document guide 33 provided on the editing instruction input surface 31.

Next, the editing instruction device 3 is used to specify the position where an underline should be drawn. This operation will be explained below.

In this embodiment, the user first presses the square key 31C in the function designation area EF+ of the editing instruction input screen 31 (see FIG. 4) shown in FIG. Next, the starting point P and ending point P2 of the underline are specified using an indicator pen (not shown).

Next, press the memory registration key 31v. In this embodiment, the memory registration key 31V has multiple functions, and normally, when the memory registration key 31V is pressed,
The set editing function is registered in a memory card (not shown) removably installed in the copying machine body 2, but after rectangle is selected as the area setting method and the coordinates of two points are input, memory registration is not performed. When the key 31V is pressed, a straight line is drawn based on the input coordinates of the two points.

However, at this time, the coordinates of the end point P2 are not stored as they are, but are transformed so that they are located perpendicularly or horizontally to the starting point P1. That is, FIG. 9(a)
As shown in , the end point P is 45 minutes from the X axis passing through the starting point P+.
If they are within degrees, the coordinates of the new end point P are determined by projecting the coordinates of the end point P2 onto the X axis. In addition, Fig. 9 (b
), when the end point P2 is within 45 degrees from Y#j passing through the starting point P1, the new end point P is the value obtained by projecting the coordinates of the end point P2 onto the Y axis.

Let the coordinates be This coordinate conversion process is performed when writing to the bitmap memory 68, which will be described later.
Performed by U63.

As mentioned above, by performing coordinate transformation of the end point P,
Even if the straight line connecting the starting point P and ending point P2 input by the user is not exactly parallel to the characters, the underline or side line will not be tilted relative to the characters in the original when outputting an image as described later. , drawn in parallel.

Next, after pressing the coloring key 31i, a color is specified by pressing the desired color, that is, the red part, in the standard color specifying section 31r or the registered color specifying section 31s provided in the function specifying area EF2.

Note that the default for the drawn straight line is, for example, 0.5.
It is a single line with a width of mm, which corresponds to a width of 2 bits in the bitmap memory 68.

If you want to change the width or number of straight lines, perform the following operations. For example, if you want to create a single line with a width of 0.75 mm (equivalent to 3 bit width), press the memory registration key 31v, and if you want to create two lines with a width of 0.5 mm, press the memory recall key 31W, If you want to create two lines with a width of 75 mm, press the area correction key 31X. This results in
When outputting an image, which will be described later, in addition to the straight lines between designated coordinate points, parallel straight lines are added adjacent to or apart from each other.

Note that here, the memory caller 31w and the area modification key 31X are used as keys for performing a function different from the original function.

After completing each of the above-mentioned specifications, the setting end key 31q is pressed. With the above operations, the editing instruction work for straight line drawing is completed.

As a result, the starting point P1 set by the editing instruction device 3
The coordinate data of and the end point P, the data that the editing type is straight line drawing, the line type data, and the color data are stored in the RA in the editing control circuit 30 provided in connection with the editing instruction device 3.
It is stored in M69 in a predetermined format.

Next, the image editing operation will be explained.

Remove the original from the editing instruction input surface 31 of the editing instruction device 3, open the editing instruction device 3 as shown in FIG. 1, and place the original on the platen glass 10 of the color image input section 1 with the image surface facing downward. do. At this time, the lower left of the document (lower right when viewed from the image side) is positioned by abutting against the document guide 22 provided in the color image input section 1.

Next, when the belly copy start key (not shown) provided on the operation panel section 21 of the copying machine main body 2 is pressed, the CPU (not shown) on the copying machine main body 2 side is connected to the host l1064.
A copy start command is sent to the CPU 63 on the editing control circuit 30 side via the CPU 63 (see FIG. 7). In response to this copy start command, the CPU 63 reads out the coordinate data and data indicating the editing type stored in the RAM 69, and provides it to the CRT C67 as a drawing command. As a result, a bit pattern corresponding to the area defined by the coordinate data is written into the bitmap memory 68. Further, a function number is written into the RAM table 72 according to the editing type.

The bitmap memory 68 has a memory surface for three screens for drawing, and is capable of drawing up to seven (=23-1) areas with different function codes. Further, each side of the bitmap memory 68 is stored in a recording paper of the maximum size that can be output by the copying machine main body 2, for example, A.
It has memory space corresponding to the width of three sizes of recording paper. Functions "1" to "7" are stored in these memory planes. For example, when drawing a red straight line, function number "2" is written at a location corresponding to the straight line from the starting point P1 to the ending point P.

After drawing on the bitmap memory 68, the CPU 63 writes in the RAM table 72 the correspondence between the function number drawn on the bitmap memory 68 and the function code. Specifically, for example, the unprocessed code r00HJ is stored at address 7200 in the RAM table.
A deletion code "80I4" is written at the address, and a red coloring code rc3HJ is written at the 2nd address.

When the above processing is completed, the CPU 63
A ready signal is sent to the CPU (not shown) via I1064. In response to this ready signal, the copying machine main body 2 side starts a copying operation. Along with this, a page synchronization signal and a line synchronization signal synchronized with the scanning of the original are output from the copying machine main body 2 side. At this time, CPU63
sends a DMA transfer command to the CRT C 67 in advance, and sequentially reads out the contents of the bitmap memory 68 in accordance with each of the synchronization signals. In order to control the timing at this time, a synchronization circuit 74 is provided in association with the CRT C67.

The signal read from the bitmap memory 68 is RA
It is converted into a function code by the M table 72 and input to the data processing circuit 75. The data processing circuit 75 decodes the function code and processes the image data accordingly.

That is, from the starting point P1 to the ending point P of the original shown in FIG.
When scanning a straight line between the areas, function codes rC3 and rC4 corresponding to red coloring are supplied, so the red signal is superimposed on the original image data and output, and the other areas are When the document is being scanned, the function code roonJ corresponding to no processing is supplied, so the image data of the document is output as is.

By the above-described operation, the specified image processing can be performed on the set area. That is, in the output image, as shown in FIG. 8(b), the characters rABCDJ are underlined Q.

Further, by the same processing as described above, it is possible to frame the image of the document as shown in FIG. 10(a) as shown in FIG. 10(b).

In this case as well, the two points P3. P
Enter the coordinates of 2, but in the case of framing, these two points P,
A rectangular frame having two diagonal vertices of , P is obtained, and a predetermined function number is written in the bitmap memory 68 at a location corresponding to the rectangular frame.

Therefore, if the image data of the document is processed while reading the contents of the bitmap memory 68, the image data shown in FIG.
As shown in c), a frame Q2 surrounding the characters r A B CDJ is drawn.

Furthermore, according to the present embodiment described below, image editing can be performed on an area having a predetermined extent centered on each input coordinate point. For example, when copying, if you set coloring to an area whose width can be changed around the input coordinates, you can add the desired thickness as if you were adding a line with a pencil, sign marker, or brush. It is possible to draw a free shape using the lines of . Note that such processing is referred to as tracing in this specification.

An example of drawing a red free shape will be described below.

First, press the free form/polygon key 31b on the editing instruction input screen 31 shown in FIG. 5, and then press the frame designation key 31.
Press a. This determines that the type of image editing is tracing.

Next, specify the freeform to be drawn. For example, the free form is a continuous curve Q3 as shown by the broken line in FIG. 11(a).
In this case, the curve Q is displayed while an instruction pen (not shown) is pressed on the editing instruction input surface 31.

trace. At this time, when a certain distance away from the input coordinates, a new coordinate point is automatically input. Note that if the shape to be drawn is not a continuous point, the coordinates may be specified discretely.

After tracing is completed, select the function.

For the traced curve Q3, coloring 1 color conversion,
Negative/positive inversion and deletion processing is possible, and one of the coloring key 3111 color conversion key 31h, negative/positive inversion key 31g, or deletion key 31 is pressed depending on the desired function. If a selection other than deletion is selected, then the color is designated by pressing the desired color portion in the standard color designation section 31r or the registered color designation section 31s provided in the function designation area Ez. Here, since red is to be drawn, the user presses the coloring key 31i and then presses the red part.

As a result of the above-mentioned operation, the traced curve Q of the bitmap memory 68 can be used in the copying operation to be described later.
, the predetermined function number, that is, the function code “2” corresponding to the red coloring
" is written. Therefore, when copying, by processing the image data of the original while reading out the contents of the bitmap memory 68, it becomes possible to draw the curve Q4 in red as shown in FIG. 11(b). Further, regarding color conversion, negative/positive inversion, and deletion, processing is performed according to each function code. By default, the processing unit is 5 units centered on the specified coordinates.
．． It is a square with a size of 0 mm x 5.0 mm, but if you want to change the size, perform the following operation. For example, if you want to make it 2.0mmX2.0alLll,
Press memory registration key 31ν, 3.5×3.5+nm
If you want to, press the memory call key 31W and press 6
．． If you want to set it to 5+++mX6.5+n+n, press the area correction key 31x.

As a result, when drawing the bitmap memory 68, the filled-in area centered on the specified coordinates changes,
The size of dots when outputting an image is determined. For example, when the size of the dot is increased, a discontinuous curve Q expressed by a combination of squares as shown in FIG. 11(C) is drawn.

Above, we have explained the case where red free shapes are drawn continuously, but the usage mode is not limited to this.
, various other usage modes are possible.

For example, if there are dots on the original image,
When copying, specify the coordinates of the center of this stain, and set deletion for a certain area containing the stain around these coordinates to correct the stain on the original using white correction fluid. You can get a clean copy in the same way.

Furthermore, one of the image processes performed by the copying machine of this embodiment is extraction movement. This extraction movement is carried out on the platen glass 10.
(See FIG. 2) The original placed on the recording paper is scanned to read the original image, and only the image in a designated area is extracted and outputted to a designated location on the recording paper.

This extraction movement will be explained in detail below.

Now, by extracting and enlarging the area R of the document sheet indicated by diagonal lines in FIG.
This will be explained using an example of moving to . Note that the size of the area R in the main scanning direction is m, and the size in the ill scanning direction is l.
Let M be the size of the area S in the main scanning direction, and L be the size in the sub-scanning direction. Also, the vertex coordinates of each region R, S are:
The calculation is performed using the end point in the main scanning direction and the starting point in the sub-scanning direction as a reference point.

First, a manuscript is placed on the editing instruction input surface 31.

Next, the editing instruction device 3 is used to specify two diagonal vertices of the rectangle to be edited.

As a specific operation, first press the square key 31C of the function designation area EFI on the 1st set instruction input screen 31 (see FIG. 4) shown in FIG. 5 to specify the editing area setting method, and then press the 12th The two vertices P,,P shown in figure (a).

Specify. Although the rectangular shape is selected here as the editing area setting method, the free shape described above can also be selected.

Next, after pressing the extraction movement key 31ITl, the extraction movement destination specification key 31y provided in the function specification area EPH is pressed.
(See Figure 4), the destination is upper left and upper right.

Select one of the five locations: bottom left, bottom right, and center. Here, assume that the lower left is selected. Note that if the extraction destination designation key 31y is not pressed, the center is automatically designated as the extraction destination.

Finally, when the setting end key 31q is pressed, the editing instruction device 3
The coordinate data of the editing area set by and the data indicating that the editing type is extraction movement are stored in the RAM 69 in the editing control circuit 30 provided in connection with the editing instruction device 3 in a predetermined format. Ru.

With the above operations, the editing instruction work for extracting and moving is completed.

Next, Figure 12~
This will be explained with reference to FIG. Note that FIG. 12 is a diagram explaining the relationship between the image on the original and the image on the recording paper, and FIG.
The figure shows the synchronization relationship between the scanning unit and the recording unit, Figure 14 shows the movement of the scanning unit, Figure 15 is a block diagram of the circuit used when performing movement extraction processing, and Figure 16 ( Fig. 16 a) is a flowchart of the main program that controls the main body of the copying machine, Fig. 16 b) is a flowchart of the program that controls the recording section, and Fig. 17 is a diagram showing signal waveforms of various parts during movement extraction processing. .

After completing the editing instruction for extraction and movement, the original is removed from the editing instruction input surface 31 of the editing instruction device 3 and placed on the platen glass 10 of the color image input section 1.

Next, when a copy start key (not shown) provided on the operation panel section 21 of the copying machine main body 2 is pressed (FIG. 16(a)
Step 101) A copy start command is sent from the CPU (not shown) on the copying machine main body 2 side to the CP 063 on the editing control circuit 30 side via the host I1064 (see FIG. 7) (Step 102) . In response to this copy start command, the CPU 63 reads out the coordinate data and data indicating the editing type stored in the RAM 69, and provides the data to the CRT C 67 as a drawing command. As a result, data indicating the editing type for the area of the bitmap memory 68 defined by the coordinate data, that is,
Function number is written. For example, region R
When extracting, a function number rN corresponding to deletion is written in an area other than area R.

After drawing on the bitmap memory 68, the CPU 63 writes in the RAM table 72 the correspondence between the function number drawn on the bitmap memory 68 and the function code.

When the above processing is completed, the CPU 63 returns to the boss)
! 1064 to the host CPU (not shown).
sends a ready signal to. In response to this ready signal, the copying machine main body 2 side starts a copying operation (step 103).

That is, a scanning start signal is sent from the CPU 31 (see FIG. 6) to the scanner motor control circuit 52, and the scanner motor control circuit 52 starts moving to the scanning section as shown in FIG. When the scanning ratio reaches a distance of y from the reference point, it is stopped (step 104), and the CPU 5
1 outputs a paper feed command to the recording unit motor control circuit 53 (step 105).

On the other hand, on the recording unit side, when a paper feed command is received (first
6, C53) Step 201) starts feeding paper at a constant speed. Step 202), when the leading edge of the recording paper reaches the head position of the recording section (Step 2o3), recording is started, and the recording section motor control circuit 53 A synchronizing signal is supplied from the scanner motor control circuit 52 side to the scanner motor control circuit 52 side, and "recording" is output as the recording unit status (step 2).
04).

When the scanner motor control circuit 52 side receives the synchronization signal from the recording unit motor control circuit 53 side (step 106
), the time required for the recording paper to reach position Y, is set in a timer. Step 1o7>, wait for the time (step 108), and at the timing when the recording paper reaches position Y, the timer shown in Fig. A memory read start address is given to the indicated memo IJ IJ + counter 40a (step 109). The memory read counter 40a specifies the read start address of the read buffer 40b that stores one line of read data obtained by the color image input device 41.

The reading buffer 40b has a length corresponding to the width of the platen glass lO in the main scanning direction, as shown in FIG. Image data for one line is stored. When editing, among the image data of the document stored in the reading buffer 40b, the address position corresponding to the area specified by the editing instruction device 3, in the example of FIG. Reading is started towards the reference point address. This address X.

is the memory read start address.

Further, the main scanning magnification signal is supplied to the enlargement/reduction circuit 40d (step 109). The enlargement/reduction circuit 40d is
By controlling the state of reading from the reading buffer 40b, the image of the document is enlarged or reduced. For example, when the main scanning magnification is 200%, the same image data is output twice, and the main scanning magnification is 50%.
%, the image data is halved and output.

The output of enlargement/reduction circuit 40d is provided to gate 40e along with the video valid signal. Therefore, the output of the enlargement/reduction circuit 40d is valid only during the image validity period on the recording paper. Nafu, the above-mentioned memory read counter 40
a, read buffer 40b, differential circuit 40C9 enlarged/
The reduction circuit 40d and the gate 40e are arranged in the signal path from the color image input device 41 to the RGB color separation circuit 42 in the block diagram shown in FIG. In addition, the 15th
In the figure, the signal path from the RGB color separation circuit 42 to the dither processing circuit 47 in the block diagram shown in FIG. 6 is shown as a color processing circuit 40f, and the dither processing circuit 4
The output of 7 is supplied to an image processing circuit 48 that performs editing processing.

Along with this, a page synchronization signal and a line synchronization signal synchronized with the scanning of the original are output from the copying machine main body 2 side.

The CPU 63 resets the address of the bitmap memory 68 in synchronization with the page synchronization signal, and thereafter sends a DMA transfer command to the CRTC 67 in synchronization with the line synchronization signal to transfer the contents of the bitmap memory 68 line by line. Read sequentially.

In order to control the timing at this time, a synchronization circuit 74 is provided in association with the CRTC 67.

The signal read from the bitmap memory 68 is RA
It is converted into a function code by the M table 72 and input to the data processing circuit 75. The data processing circuit 75 decodes the function code and processes the image data accordingly.

That is, when scanning an area other than the document area R shown in FIG. 12, the function code r corresponding to deletion is
80. " is supplied, so the image other than area R of the document sheet is deleted and output. Also, when scanning area R, the function code rO (hJ is supplied, which corresponds to no processing). The image data of the original is output as is. It is assumed that the bitmap memory 68 has a function number "0" corresponding to no processing written as an initial value.

By the above-described operation, the specified image processing can be performed on the set area.

On the other hand, on the recording unit side, as shown in FIG. 12(C), a video valid signal having a width corresponding to the width M in the main scanning direction of the area S of the recording paper is output (step 109). The rising edge of is differentiated by the differentiating circuit 40C and becomes a load signal, which is supplied to the memory read counter 40a. Therefore, the memory read start address is loaded into the memory read counter 40a at the rising edge of the video valid signal, and the reading start position in the main scanning direction of the document is determined.

Further, as shown in FIG. 12 (6), a line synchronization signal having a width corresponding to the width of the recording paper in the main scanning direction is output. Note that this line synchronization signal (see Figure 17 (C))
and the aforementioned video valid signal (see FIG. 17(b)) are output in synchronization with the line reference signal generated every time the main scan starts as shown in FIG. 17(a).

Next, the movement to the scanning unit is restarted, and while reading the image of the original up to position y2 (step 110), recording is performed on the recording paper (step 204). At this time, the scanning speed is
It is the reciprocal of the magnification. In the example shown in Figure 12, the magnification is L
/p, so the scanning speed is A/p when the magnification is 100%.
Multiply by L. Note that at this time, the conveyance speed of the recording paper is constant. Further, in the enlargement/reduction circuit 40d shown in FIG. 15, image data is outputted repeatedly or thinned out depending on the magnification.

As a result, the recording paper is multiplied by M/m in the main scanning direction and L/j! in the sub-scanning direction. The multiplied image is output between XI and Xi 0 in the main scanning direction and between Yl and Yl in the sub-scanning direction.

When the scanning unit reaches position y2, it stops scanning, turns off the video enable signal, and reverse scans the scanning unit to the home position, that is, to the reference point (0,0), as shown in FIG. (step 111).

Furthermore, when the recording section finishes recording on the recording paper, it outputs "paper discharge complete" as the recording section status (steps 205 and 206).

On the main program side, the recording unit status is monitored after scanning is completed, and if the recording unit status is "recording", it loops to step 112, and when it becomes "paper discharge complete", it returns to step 101 and completes all processing. ends.

Another type of image processing in the copying machine of this embodiment is similarity synthesis. In this similar synthesis, an original for the color output section is placed on the scanning start side, that is, the first half, on the platen glass 10 (see Figure 2), and an original for the black and white output section is placed on the remaining half, that is, the latter half. Place a portion of the image on one document, keeping the aspect ratio constant.
That is, it is fitted into a part of the other document in a similar state.

In this embodiment, when compositing, an area is drawn on the bitmap memory 68 at the same position and with the same size as the embedding area of the composite light image. Then, when reading the image of the original using composite light, processing is performed with the area outside the area set to be deleted and the area inside the area set to no processing. Also,
When reading a composite light original image, processing is performed with the area outside the area set to no processing and the area inside the area set to deletion. At this time, the same content is read out from the bitmap memory 68 twice: when reading the image of the original using combined light and when reading the image of the original using combined light.

Through the above-described processing, the images of both documents are combined.

At this time, the area of the compositing source image or the compositing light image is corrected so that the magnification in the main scanning direction is equal to the magnification in the sub-scanning direction.

Furthermore, it is important to note whether the first half of the document is a synthetic light document and the second half of the document is a synthetic light document, or whether the first half of the document is a synthetic light document and the second half of the document is a synthetic light document. , can be specified arbitrarily.

Hereinafter, similar synthesis will be described in detail when the first half of the document is a synthetic light document and the second half of the document is a synthetic light document.

Now, as shown in Figure 18(a), the first half of the A4
As an example, assume that the image of the specified area R2 of the A4 size original D1 is inserted into the specified area R2 of the A4 size original D2 in the second half, and the images of both originals, D, are combined. List and explain. Note that the size of region R8 in the sub-scanning direction is defined as width β from position y to y2, and the size in the main scanning direction is defined as width m from position x2 to XI. Further, the size of the area R2 in the sub-scanning direction is set to a width starting from a distance Y from the boundary position y of the document DI and D2 toward the document D2 side, and the size in the main scanning direction is set to a width starting from a distance Y from the boundary position y of the document DI and D2. Width ~・1. In addition, here, (M/
m) X100 = 130 (%) and (L/f
) X100 = 240 (%). Further, the vertex coordinates of each region R, , R2 are calculated using the end point in the main scanning force direction and the starting point in the sub scanning direction as a reference point.

First, as shown in FIG. 3, the editing instruction device 3 of the copying machine is closed, and the document to be edited is placed on the editing instruction input surface 31 with the image side of the document facing upward.

Next, the editing instruction device 3 is used to specify two diagonal vertices of the rectangle to be edited.

Specifically, the user first presses the square key 31C in the function designation area EFI of the editing instruction input screen 31 (see FIG. 4) shown in FIG. After specifying the editing area setting method, the two vertices p, , p shown in FIG. 18(a) are set.

Specify. Although the rectangular shape is selected here as the editing area setting method, the free shape described above can also be selected.

Next, after pressing the quick copy synthesis key 31n, the two diagonal vertices P of the area R1 of the document D2 in the latter half are selected using an indicator pen (not shown). , P, is input.

Next, the memory caller that functions as a similar composition key -
31W and finally, the setting end key 314, the coordinate data of the editing area and the type of editing set by the editing instruction device 3 are stored in the editing control circuit 30 provided in connection with the editing instruction device 3. The data is stored in the RAM 69 in a predetermined format.

With the above operations, the editing instruction work for similar composition is completed.

Next, we will explain the similar composite image editing operation in Figures 18 to 2.
This will be explained with reference to FIG. Note that FIG. 18 is a diagram explaining the relationship between the image on the original and the image on the recording paper, and FIG. 19 is a diagram showing the synchronous relationship between the scanning section and the recording section during the similarity synthesis process.
FIG. 20 is a diagram showing the movement of the scanning section.

After completing the editing instruction for similar composition, remove the original from the editing instruction device 30 and the editing instruction device 31, open the editing instruction device 3 as shown in FIG.
Place the original document, D, on the platen glass 10 of , with the image surface facing downward.

Next, when a copy start key (not shown) provided on the operation panel section 21 of the copying machine main body 2 is pressed, the CPU (not shown) on the copying machine main body 2 side is connected to the host l-106.
A copy start command is sent to CP 063 on the editing control circuit 30 side via 4 (see FIG. 7). In response to this copy start command, the CPU 63 reads out the coordinate data and data indicating the editing type stored in the RAM 69, and provides it to the CRT C67 as a drawing command. As a result, a predetermined area is written to the bitmap memory 68 based on the coordinate data, and data indicating the editing type, that is, the function number is written to the RAM table 7.
2 is written.

When writing to the bitmap memory 68, the writing area is determined based on the size relationship and the aspect ratio of the areas R1, R1 of the original document D2. Here, the magnification in the main scanning direction is 130% and the magnification in the sub-scanning direction is 240%.
%, an area R3 obtained by enlarging area #cR+ of the original D1 in the main and sub-surface scanning direction at a magnification of 130% is written into the bitmap memory 68. As mentioned earlier, the bitmap memory 68 corresponds to the A3 size, and in the part of the A4 size on the start address side of the bitmap memory 68 (shown by the broken line in FIG. 18), Region R5 is drawn with the same image as that output on the recording paper.

Then, when scanning the first half of the original document to be combined, a correspondence table between function numbers and function codes in the RAM table 72 is set so that the area inside the area R3 is not processed and the area outside the area R5 is deleted. do.

When writing to the bitmap memory 68 is completed, C
A scanning start signal is sent from the P U 51 to the scanner motor control circuit 52, and the scanner motor control circuit 52
As shown in FIGS. 9 and 20, movement of the scanning section A is started. When the scanning unit reaches a distance of yl from the reference point, the movement is stopped, and the CPU 51 outputs a paper feed command to the recording unit motor control circuit 53, and the scanner motor control circuit 52 side controls the recording unit motor control circuit. It will wait for a synchronization signal from the 53 side.

In addition, on the recording unit motor control circuit 53 side, when a paper feeding command is received, paper feeding is started at a constant speed, and the leading edge of the recording paper reaches the head position of the first recording unit, that is, the yellow recording unit 24Y. Then, recording is started, and a synchronization signal is supplied from the recording unit motor control circuit 53 side to the scanner motor control circuit 52 side (see FIG. 13).

When the scanner motor control circuit 52 side receives a synchronization signal from the recording unit motor control circuit 53 side, the recording paper moves a distance Y.
The time required for passing the document D1 is set on a timer and the recording paper waits for a certain amount of time, and when the recording paper has moved a distance Y, it resumes moving to the scanning section and continues recording while reading the image of the document D1 up to position y2. Record on paper. At this time, since the reading start position is controlled based on the input coordinate information in the main scanning direction, the image of the area R2 of the document D2 is output to the area R2 of the document D2.

The contents of the bitmap memory 68 are sequentially read out in synchronization with the scanning of the original, but since this is the same process as the extraction and movement process, the explanation will be omitted.

The signal read from the bitmap memory 68 is RA
It is converted into a function code by the M table 72 and input to the data processing circuit 75. The data processing circuit 75 decodes the function code and processes the image data accordingly.

That is, when scanning an area within area R1 of document D1 shown in FIG. 18, a function code corresponding to no processing is supplied, and when scanning an area outside area R1, a function code corresponding to deletion is supplied. Since the function code is supplied, an image of only the area R is output on the recording paper.

At this time, the scanning speed in the sub-scanning direction to the scanning section is
1 and the magnification in the main/subsurface scanning direction of the area R2, whichever is smaller. In the case of the example shown in FIG. 18, the magnification L/1 in the sub-scanning direction is 240% and the magnification M/m in the main scanning direction is 130%.
At the same time, the magnification in the sub-scanning direction is made to match the magnification in the main-scanning direction, and is also expanded to 130%. In other words, the scanning speed is 7 when the magnification is 100%.
Make it 7%. At this time, the conveyance speed of the recording paper is constant. Note that in the main scanning direction, scaling is performed by the same process as in the case of the extraction movement process described above.

Next, the scanning section is moved to the scanning start position y of the document D2 using the composite light in the latter half, and waits for a synchronization signal from the recording section.

When the leading edge of the recording paper reaches the fourth recording section, that is, the black recording section 49K, a synchronization signal is supplied from the recording section motor control circuit 53 side to the scanner motor control circuit 52 side.

When the scanner motor control circuit 52 side receives the synchronization signal from the recording unit motor control circuit 53 side, it resumes the movement of the scanning unit A, and records the image on the recording paper while reading the image of the document D2 up to position y. I do. At this time, the RA
The correspondence table between function numbers and function codes in the M table 72 is rewritten. As a result, the same pattern as in the scanning of the first half is read from the bitmap memory 68, but the area outside the area R3 is not processed and the area inside the area R3 is deleted, so that on the recording paper,
As shown in FIGS. 18 and 18), an image of the area excluding area R5 of the document D2 is output around the image of the area R1 of the document D enlarged to 130% in the main and sub-surface scanning directions. The scanning speed at this time is the speed when the magnification is 100%.

Therefore, as shown in FIG. 18(b), the image of the region R3 of the document D1 is fitted into a part of the image of the document D1 while maintaining a similar relationship. In this way, even if the aspect ratios of the edit designated areas in each document do not match, both images can be combined without changing the aspect ratio of the original images, so the combined image will not look unnatural. Never. Further, since there is no gap between the images of the two originals, the images do not become unsightly.

〔Effect of the invention〕

As described above, in the present invention, a pattern corresponding to a straight line connecting a plurality of points specified by the coordinate input means is written into the bitmap memory, and when the original image is scanned, it is synchronized with this. The contents of the bitmap memory are read out, and when the pattern is detected, specific image data, such as a red image, is superimposed on the original image and output. As a result, an output image in which red straight lines, rectangular frames, etc. are superimposed on the original image is obtained.

Therefore, for example, it is possible to obtain a copy in which the characters of the original are underlined in red or the characters are surrounded by a red frame. This makes it easy to edit images to emphasize or make characters stand out.
