The density signal DS converted into a digital signal by the AD converter 41 is input to the color processing circuit 42, where it undergoes color correction, sharpness emphasis 1 gradation conversion processing, etc., and the color-processed image information is stored in a buffer. The data is input and stored in the memory 43. and,
The information stored in the buffer memo IJ431C is converted into an analog signal by the DA converter 44, and then input to the modulator 45 in the laser beam printer, and the information is output by the laser beam (three colors of blue, green, and red) from the laser oscillator 46. The color paper 31 pasted on the output drum I is exposed through the output head 32 by modulating laser light or three laser beams with different wavelengths for false color. Note that the output head 32 is operated in the X direction (sub-scanning direction) via a pulse motor and a lead screw 34 connected thereto.
It is set to be moved to K.

On the other hand, a console equipped with a keyboard is provided as a data and command input device, and data input from the console is transferred to a computer (minicomputer).
The computer 51 is further connected to a microprocessor 53 of a lower system, and the microprocessor 53 performs color processing. Circuit 42 and buffer memory 43
and are mutually connected by a pass line father. The computer 51 and microprocessor 53 constitute a computer system, and buttons are provided to display instructions to the operator etc. on the graphic display 52 according to a built-in program. Further, the X position of the reading head 16 is detected by a linear encoder 17 engaged with the guide rail 18, and the position information is inputted between the timing control circuits, and the output head 3
The X position of No. 2 is also detected by the linear encoder 35 engaged with the guide rail 36, and the position information is input to the timing control circuit 55.

The above is a schematic configuration of an image input/output system to which the input original image positioning method of the present invention is applied. Next, the coordinate relationship between each device will be explained.

First, coordinate transformation during digitizer addition will be explained.

Although the digitizer has origin coordinates and X-Y axes unique to the device, the origin can be moved to any point by operation, and the coordinates can also be easily rotated. That is, in Fig. 3, the origin OD, which is unique to the device, and the horizontal axis are x
D, the vertical axis is YD, and the new 17 origin is set to 0 by operation.
1. Set Xl as a new point on the X-axis using the digitizer 20.
After inputting to point 01 and XI K, any point (Xl
), yD) are transformed by n n points of the new coordinate system (xn+Yn) l'-linear equation.

However, θ is the angle between the straight line QtXs and the device-specific X9 axis, and the counterclockwise direction is positive. However, the above (
1) All calculations of equations are to be performed by the computer 51.

Next, management of coordinates on the input/output drum will be explained.

In the input drum 10 and output drum force, main scanning (
The rotation) direction is the y-axis and the Y-axis, and the sub-scanning (horizontal running) direction is the X
and the X-axis. The coordinates of the read head 16 are thus determined within the timing control circuitry in the following manner.

That is, regarding the y-axis, the output of the four-tary encoder 13 connected to the rotation axis of the input drum 10 is input to the PLL (Ph
After resetting the counter at the origin of the y-axis, the X coordinate is determined as an absolute address by counting the output pulses of the PLLN path. Incidentally, the period of the output pulse of the PLI circuit is determined by the relationship [μ
] or 10 (μ).Furthermore, on the %X-axis, the position of the reading head 16 is determined by counting the output pulses of the linear encoder 17 after resetting the counter at the origin of the X-axis. The X coordinate of the output drum force is managed as an absolute address.The X coordinate of the output drum force is also managed in the same manner as the input drum.The X coordinate of the output drum force is ) are rotating synchronously, so they are managed in the same way as the X coordinate.

Next, a specific method of positioning the input original image according to the present invention will be explained.

The coordinate systems of the digitizer (9) and the input drum 10 are made to correspond to each other through, for example, a rectangular transparent base 11 as shown in FIG. That is, the transparent base 11 is formed of a flexible rectangular sheet-like transparent material, and two register pin holes 11A and IIB are provided along its upper side. In addition, when adding a digitizer, the register pin hole 11 of this transparent base 11 is
A, two resistor pins 21 that engage IIBK,
22, and when mounting the transparent base 11 with the original pictures A to D pasted on it on a digitizer, as shown in FIG.
2 to position it. Furthermore, a positioning unit similar to the digitizer is added to the input drum 10.
A pair of register holes 61A and 61B are provided, and even when the transparent base 11 on which the original pictures A to D are pasted is mounted by winding the input drum 10IC, the pin holes 11A and 61B are provided.
Positioning is performed by engaging IIB with the pin.

In this way, since the user is busy attaching the M-light base 11 to the digitizer and attaching it to the input drum 10 by positioning it by engaging the pin holes 11A and IIB with the pins, the color original image A pasted on the transparent base 11. The coordinates of ~D on the digitizer m and the coordinates on the input drum 10 can be easily correlated.

By the way, in the above-mentioned image specific force apparatus to which the input original image positioning method of the present invention is applied, two types of input regarding figures such as coordinates are prepared.

One is a figure input that specifies the shape of the output screen, and the other is a base document input that specifies which figure on the output screen the color original images A to D for reading should correspond to. Graphic input is an operation in which a graphic is input from the digitizer and the graphic is made to correspond to the screen on the output drum, and this operation is similar to the graphic input normally performed in a block drafting machine. In addition, base document input can be performed using multiple color originals (A
~D) The correspondence between the coordinates of the transparent base 11 pasted thereon and the input drum 10 is shown in the register pin hole 11A as described above.

11B and a pair of register pins 61A and 61B, the main purpose is to correlate the positions and magnifications between each color original image on the transparent base 11 and the above-mentioned input figure. It is a function.

Next, the graphic input operation will be explained. In this operation, first, the coordinates added by the digitizer are associated with the coordinates of the output drum (9). That is, in FIG. 6, bamboo is the origin specific to the digitizer, paddle and YP are points on the horizontal and vertical axes specific to the digitizer, and 0T1) is the point above the digitizer head corresponding to the origin of the output drum 30. point, X
11) and yT) are a point on the X-axis of the output drum I and a point on the digitizer corresponding to the point on the X-axis. Therefore, set the point monument and xl) so that the straight line q dimension and ol, An arbitrary point above the digitizer head (< It can be converted to quadratic coordinates.

Therefore, when the output size on the output drum I is first specified using the console function, an output size frame converted at an appropriate ratio is displayed on the graphic display 52. Then add the digitizer to the figure code (rectangle 9 circles)
When the necessary coordinate points are input as a block figure, the above-mentioned coordinate transformation and magnification conversion for display on the graphic display 52 are calculated in the computer 51, and the figure is displayed at the specified position and size on the graphic display 52. Is displayed. Each time the computer 51 inputs a graphic code and a coordinate point, it controls the graphic display 52 so that the frame and the graphics input so far are superimposed and output. In this way, the block figure (rough sketch) is input, but the graphic display 52
The operator uses this to perform visual confirmation. In this case, when the figures overlap, it is necessary to perform the hidden surface processing of the figures as described below, or to input hidden surface designation in the digitizer and console section, to remove hidden surfaces in the computer 51. After processing, final draft information is created. However,
The output screen displayed on the graphic display 52 is a figure 01 superimposed as shown in FIG. 7 (5), for example.
~In the case of G3, use the console group to perform, for example, '
By performing the input operation Gl(G2, G2)G3', hidden surface processing as shown in FIG. 7) is performed.

Next, base document input will be explained with reference to FIG. 8 (4).

° Pace manuscript input is also done through digitizer addition,
In this operation, first, the coordinates of the transparent base 11 on which the color original pictures A to D are pasted are correlated with the input drum 10, and then the respective color original pictures on the transparent base 11 are input by the above-mentioned figure input operation. The correspondence relationship with the block diagram
The main function is toroko, which is performed via the console. Then, the transparent base 11 on which the plurality of color original pictures A to D are pasted is connected to the register pins 2], 2.
2, position it and fix it on top of the digitizer. Then, the coordinate system of the transparent base 11 fixed above the digitizer head is converted to the coordinate system of the input drum 10.
This is done in the same way as the seat frame conversion from digitizer gloss to output drum function explained in the graphic input operation. Next, the previously input block diagram and the original drawings A and D on the transparent base 11 are
Associate the magnification with the coordinates of . That is, Figure 8 GA)
, In (B), output figure A' corresponds to original picture A, but in order to make broken line A1 in original picture A correspond to figure A', one point in original picture A and one point in figure A' must be If the coordinates of the points are made to correspond and the magnification at which the break l[A1 in the original image A is enlarged or reduced to the figure A' can be specified, the coordinate relationship is uniquely determined. To do this, for example, one point in figure AI and one point in original picture A may be made to correspond in coordinates by inputting their positions using a digitizer, and a magnification value (5) may be input at the console. Original picture B, C, D and output figure H/
, C/, D'Ic.

Next, coordinate management between the coordinates of digitizer A and the coordinates of input drum 10 and output drum 30 will be explained.

First, the color paper 31 attached to the output drum 30
The position and shape of the layout output of the original image on top.

Input the size as a block diagram using a digitizer,
We will describe a method for defining each shape on the buoy thread (block coordinate system) that defines the block figure and managing each defined figure.

FIG. 9 shows a transparent pace 11 attached to the input drum 10.
The image of the range 101, 201 shown by the frame of the input original picture 100, 200 pasted on the color paper 31 mounted on the output drum 30 is shown by the border 101A, which is indicated by diagonal lines.
The case where the layout is output to 201A is shown,
In the following explanation, the input original image 100 is used as the output drum 3.
A case will be described in which a layout is output to an area indicated by diagonal lines on the color paper 31 mounted on the color paper 31, that is, the range of the block diagram 101A. In the following description, each coordinate system is defined such that the coordinate origin is at the upper left, the X axis is from left to right, and the Y axis is from top to bottom, as shown in FIGS. 9 to 11.

By adding the digitizer, the coordinate origin ♂ of the block diagram 101 shown in FIG. 10 and one point on its Xo or yH@ are designated. As a result, the coordinate values of each specified point are input to the computer 51, and the computer 51
1 calculates the deviation between the coordinates added by the digitizer and the coordinates of the specified block figure. At this time, if the coordinate origin q and point X on the X-axis of the block figure above the digitizer are input, and their coordinate values are input, the coordinates of the block figure will be on the coordinate system of digitizer 2). The computer 51 recognizes that the item has been specified to be translated in parallel in the XR and yD directions in the X9 direction, and further rotated by an angle θ shown by using this point as a reference. Furthermore, if the coordinate values of digitizer 2 (digitizer 2I of any point on the block diagram measured by 'i)-F are <xD, yD>, then the coordinate values of the block coordinates '2 of this point are <xH , yH) is expressed as 1 [Yν1] . The coordinate values of are converted to the coordinate values on the coffin/lower figure.

When the coordinates of the hatched figure 101A of the block diagram are input from the digitizer, the computer 51
is recognized as a figure converted into coordinate values on the block coordinates by the calculation process of equation (4) above. (Thus, the figure 101A recognized as a figure on the block coordinates further defines in the computer 51 a rectangle 102 that circumscribes the figure 101A and is parallel to the xHyH axis of the block coordinates, and also defines the block coordinates of the rectangle. The vertex that is closest to the origin] 02A is the coordinate origin (point point), and 17 defines a coordinate system with axes (XK-YKQ) parallel to the 11 and 1 axes of the block coordinates, that is, a shape coordinate system, The block diagram 101A is defined as figure 1 on the shape coordinate system.
It can be recognized as 01B. This process is related by the following equation (5). That is, the shape r!
If the coordinate values of the origin φ of the ¥ standard system on the block coordinates are (kai, cost), and the coordinate values of any point on the block diagram 101A on the block coordinates are < xH, yH), then this The coordinate values (xK, yK) of the point on the shape coordinates are expressed as [Dimension Y Ken 1].

Conversely, the block diagram 101A passes through the origin φ of the shape coordinate system, and the diagram 101B is inscribed in a rectangle parallel to the xHyB axis.
It can also be recognized as a figure that has been translated in parallel to the specified position 102AK on the block coordinate system. and,
Conversion from shape coordinates to block coordinates is performed by [ma;yH1:]. In addition, in the internal processing of the computer 51, the figure 101 inputted from the digitizer
A is the figure 10 on the shape coordinate system after the above-mentioned conversion process.
The block diagram 101A can be managed using the graphic information of 1B and the conversion parameters from the shape coordinate system to the block coordinate system <, yl;. In this case, by making a one-to-one correspondence between the block coordinates and the position coordinates (output drum coordinates) on the output drum (9), the block figure information held by the computer 51 can be transferred to the color paper attached to the output drum. It can be reproduced on the coordinates of 31. As a result, the layout conditions specified by the digitizer-added block shape can be applied to the color page.
It is possible to output a bar 31K image.

Next, the position of the original picture pasted on the transparent base 11.

A method of inputting the shape and size using a digitizer, defining an original image on a base coordinate system (a coordinate system that defines an original image), and managing each defined original image will be described.

In FIG. 11, a transparent base 11 on which an original picture 100 is pasted
Attach it to the digitizer and use it in the same way as inputting the block shape.
The coordinate origin ♂ of the coordinate system (base coordinate system) on the transparent base 11 and the yB axis or yB of the base coordinates! The coordinate values above the digitizer head of the fish tank on the axis are input to the computer 51, and in the computer 51, the coordinates added by the digitizer are converted to the block coordinates by conversion parameters θ, -XP,
In the same way as determining -YP, the conversion parameters a', -xp', and -dimension' for converting the coordinates added by the digitizer to the coordinates (base coordinates) of the transparent base 11 are determined. Then, the original 1ij on the transparent base 11 attached to the digitizer
The position and size of i100 are set at the bending point 10 on the outer periphery of the original image.
The coordinate values above the digitizers 3 to 106 are read, and the computer 51 internally converts the read coordinate values to 0/
, Recognize as position, shape, and thickness. Furthermore, similarly to the block diagram, the computer 51 defines a rectangle 110 that circumscribes the original image 100 and has each side parallel to the XB or yB axis of the base coordinates, and defines the vertex 110A closest to the origin OB of the base coordinates of the rectangle. As the coordinate origin (point 09), place it on the base coordinates XB and H axes! A coordinate system having parallel axes (xG-yG axes), that is, an original coordinate system, is defined, and the size and shape of the original image 100 on the pace coordinates can be recognized as a figure 100A on the original coordinate system. . In this process, for example, the original image 100 on the transparent base 11 is
Is the coordinate origin 0 on the original coordinate system? Let the coordinate values on the base coordinates of It is recognized as a result of parallel movement by YP.The transparent base 11 on which the input document 100 recognized in this way is pasted is attached to the input drum 10, and the register pins 61A and 61B of the input drum 10 are attached to the transparent base 11. Since pin holes 11A and IIB are provided for attachment to the input drum 10, the coordinates on the transparent base 11 can be regarded as the coordinates on the input drum 10.

As a result of the above processing, inside the computer 51,
The output position, shape, and size of the original picture on the Deka Drum Garden,
The position, shape, and size of the input document 100 attached to the transparent base 11 on the input drum 10 are recognized.

When outputting an image from the original image 100 to the output drum J in the shape specified by the draft pattern 101A, it is necessary to define the image output range and output magnification on the input document, which will be explained below.

By the way, when inputting the block diagram 101A, the console
If the output magnification S is specified in advance by
01B is scaled and projected onto the document coordinates. As a result, as shown in FIG. 12 (coordinate values c xK , yK of an arbitrary point on the block diagram 101C converted to shape coordinates wh)
The coordinate value 3 < XU on the original coordinates, Y(th) is expressed as 4 [XqYG1] 4 . At this time, the states of the input coordinates 100A and the block diagram 101C defined on the original coordinates are converted from the original coordinates to screen coordinates and displayed on the screen of the graphic display 52.

However, since the correspondence with the image output range has not been established for the draft figure defined on the document coordinates displayed at this time, The coordinates are read, and the coordinate values are converted into coordinate values on the document coordinates using the coordinate conversion formulas shown in equations (3) and (4) above, with parameters θ, -dimension/, -distance/. Then, the cursor is displayed on the screen corresponding to the position specified by the digitizer by converting it into screen coordinates, and the cursor is moved to the position specified by the NC digitizer as shown in Fig. 13 to draw the block diagram on the screen. Specify reference point 5PIA of 101D. Similarly,
On the input document attached to the digitizer 20,
The reference point STI of the input document 100A corresponding to the reference point 8P1 of the block diagram 101C shown in the figure is designated. With this designation, the coordinate values of the reference point SPI of the specified draft figure 101C on the document coordinates (< xD , yD ) are translated in parallel to the coordinate values (xD , yD ) of the reference point 8T1 of the input document, and the input document 100A The upper image output range 101E is defined. At the same time, the reference point 8P1 is also displayed on the screen of the graphic display 52.

Corresponding to 8T1, the reference point 8PIA of the draft figure 101D is translated in parallel to the reference point 5TIA of the input original 100B, and the image output range 101E on the input original is displayed in a specified manner. Through the above processing, for example, the coordinate value <xNe f ) of an arbitrary point on the block diagram 101B defined by the shape coordinates is converted by the coordinate value (X, Y?) of the document coordinates according to the following equation.

[X? Rod 1] ・・・・・・・・・・・・ (8) However, 1. x, =) (X) XI), Δy1=y¥
-The size is

When the block diagram 101B defined in the shape coordinates is converted into pace coordinates and defined by the Kakaro coordinate conversion process, the block diagram 101E defined in the base coordinates becomes the input document 10.
This indicates the image output range of 0.

In this case, the coordinate origin of the block drawing figure 101B in the shape coordinates, that is, the coordinate value of the base coordinate point B81 corresponding to the block block coordinate point 102A, is XB=kaiju ΔXi, y
It is represented by B=yTffi+Δy1. At this time, point 10
The coordinate values of the block coordinates to 2 are indicated by x”=kai, !=deaf.

10,000, and if the output magnification S is not specified when inputting the draft figure 101A, consider a magnification (for example, 70%) that is smaller than the original image defined in the document coordinates. In other words, the original 100A defined on the original coordinates
The maximum value of the coordinate values in the X-axis and yG-axis directions is the helmet and stomach,
When the maximum values of the coordinate values in the two axes and the two axes directions on the graphic of the block diagram 101B defined in the shape coordinates are the X pot and Y axis, select the magnification S1 that becomes 1
01B is defined on the document coordinates. Through this processing, the coordinates of any point on the block diagram 101B on the shape coordinates, Y?
) is represented by [XGYG1] 44 .

In this way, the shape 100A of the original picture and the block diagram 10
The state in which 1C is defined is converted from the original coordinates to the screen coordinates of the graphic display 52 and displayed on the graphic display 52. Since no correspondence is specified, the coordinate values of the input document on the transparent base 11 attached to the digitizer 20 are read and the coordinate values are determined. Then, the digitizer 20 converts the coordinates into screen coordinates and displays the cursor on the screen at the position specified by the digitizer 20.
The block diagram 101C displayed as shown in Figure 4 (5)
Move the cursor to the reference points SNI and SN2 and designate these as the reference points. Similarly, in the input document on the transparent base 11 attached to the digitizer head,
Reference points SNI and SN2 of the block diagram designate the corresponding reference points PNI and PN2 of the input manuscript. With this designation, the computer 51 determines the reference point SNI, 8N2 of the block diagram 101C on the document coordinates and the input document 1.
The reference points PNI and PN2 of 00A are made to correspond. Therefore, the reference points SNI and SN2 of the block diagram 101C
And the coordinate values of the reference points PNI and PN2 of the input document 100A are SN 1 = (X?.

pNl=(culm2゜Y?2), PN2=(X?3.Y?
3), the parallel movement amount ΔX2 tΔy2 and the magnification S2 are as follows.

(12) In this way, the magnification of the block diagram 101C on the document coordinates is converted and translated in parallel on the document coordinates. As a result, the coordinate value of any point on the block diagram 101B on the shape coordinates < xK
, yK ) on the document coordinates (X?,
(Blue) is shown as [Size 1] ・・・・・・・・・・・・ (13) As a result of the above, the block diagram 101 on the original coordinates
C is a figure 101 that corresponds to the shape 100A of the original.
BK converted. This situation is shown in FIG. 14 (N). This result is converted into screen coordinates and displayed on the graphic display 52, and it is determined whether the displayed block diagram (29) 101E and the original image 100B are in the desired positional relationship. This situation is shown in FIG. 14 (13).

If they are not compatible, the reference point SN as described above
Instruct the association of I, SN2, PNI, and PN2 again. In addition, Figure 14, (B) is the original picture 100
The relationship between the original coordinates and the screen coordinates for the original image 200 is shown, and the same applies to the original image 200.

From the above, each coordinate value (
The size, ■) is [X''9Y'71) Through the coordinate conversion process, the block figure 101B defined in the shape coordinates is converted to the base coordinates, and the block figure 101E defined in the base coordinates is converted to the input manuscript. This indicates the image output range.The output magnification S at this time is 5=82, and the coordinate origin J of the block diagram 101B in the shape coordinates, that is, the point ()1 on the block coordinates, on the base coordinates corresponding to 102A. The coordinates of point B81 are
xH=Kariju ΔX2. ¥8=wage Δy2. The coordinate values of the origin OW on the block coordinates are xH=xH, yF'1-
This is YH. (Then, the position and shape of the image output to the card drum specified by the input of the block diagram 101A, and the image output when the original image 100 pasted on the transparent base J1 is attached to the input drum 10. The range and output magnification are determined.The origin 102A on the block coordinates corresponding to the shape coordinate origin OK for sizing, and the origin 102A on the base coordinates. The coordinates are associated with the origin BSI on the base coordinates in order to correspond to the image output range of the original image.

Coordinate conversion and coordinate management between devices are performed as described above. Next, the operation of the image input/output system described above will be explained.

Using a digitizer and a console, figure codes and position information necessary for the layout of the output image are input into the computer 51, and the computer 51 generates figures according to the input figure information, and displays the generated figure data on a graphic display. 52 for display. Then, the operator judges whether the figure is good or bad while looking at the screen displayed on the graphic display 52, and if corrections or additions are needed, they are corrected using the digitizer and the console. It should be noted that the input of the block diagram is similar to that of a commonly used block drafting machine, and it is also possible to use a Lite Ben.

Next, as shown in FIG. 5, the color original pictures A to D to be output as a layout are pasted onto a transparent base 1, and the bin holes 11A and IIB of the transparent base 11 are engaged with the bins 21 and 22 of the digitizer. This will position it and set it at the predetermined position #. Then, the color original pictures A to D corresponding to the above-mentioned input figures are sequentially selected by instructions to the digitizer 20 IC and key operations on the console, and the hiding process of the figures and the output range for the color original pictures A to D are specified. . Here, the output range can be specified by specifying two points on the diagonal line in the case of a rectangular figure.
In the case of a circular figure, this is done by specifying the center point. Furthermore, the color original pictures A and D are output as figure A' on the screen.
-D', and at the same time input processing condition parameters necessary for color correction processing and sharpness emphasis 9-gradation conversion processing using the console.

Next, the computer 51 calculates the starting position and ending position of the color original picture CP on the output drum (screen) according to the main scanning line, as shown in FIG. 15, for each input graphic unit. Store it in a storage device such as a magnetic disk. That is, the X-axis position Hxt at which the scanning line in the arrow main scanning direction first crosses the color original CP is stored, and the Y-axis position Hxt at which this scan 15Xt passes over the color original CP is stored.
The starting point Y7 and ending point Y0 on the axis are stored. Similarly, for the next scan +1lX2, the X-axis position do.

Accordingly, the graphic data of the color original picture CP stored in the storage device is as shown in Table 1 below for the example shown in FIG.

Table 1 The graphic data of such a color original image is displayed on transparent base 11.
Each original picture pasted on the screen is stored in sequence.

Next, transparent base 1 to which color original pictures A to D are pasted
Positioning is performed by engaging the register bins 61A, 151B of the input drum 10 with the bin holes 11A, IIB of the input drum 10, and the input drum 10 is mounted. However, the motor 12
K drives the input drum 10 (output drum 30
) is rotated in one direction, but a rotary encoder 13 is attached to the rotating shaft of the input drum 10, and its output pulses are input to two address registers in a timing control circuit managed by a microprocessor. It is now possible to do so. The - address register is for managing absolute coordinates in the rotation direction (main scanning direction), and the other address register is for managing relative coordinates of input pixels. Here, absolute coordinates and relative coordinates will be explained. The absolute coordinates are used to manage the coordinates of each input and output quadrum, and are counted based on the origin of each Okawa quadrum. The aforementioned B81, BS2
, 102A, 202A, etc. are managed using these coordinates. It is also used to control the coordinates of the output pixel as shown in FIG. 17 (+3). On the other hand, relative coordinates are used for managing input pixels. Figure 17 (A),
In (13), in the device described here, the output pixel size is constant, and the magnification conversion is performed by changing the sampling pitch of the input pixels while keeping the same size on both the x and y axes. That is, the size of the input pixel is changed K.

The sampling timing control of input pixels whose sampling pitch has been changed is performed using relative coordinates. Note that the magnification conversion method in the y-axis direction should be the one normally used in color scanners (the magnification conversion in the This is done by driving at a constant speed and changing the rotational speed of the pulse motor 14 on the input drum 10 side.The positions of the reading head 16 and output head 32 in the sub-scanning direction are controlled by timing control of the linear encoder 17 and its output. This is determined by counting the address register in the circuit.

Here, if the reading head 16 of the input drum 10 is separated by Xl from the start position SP, and the output head 32 on the output drum is separated by Xl from the start position SP, and if the magnification is M, then the reading head 16 The output head 32 will move M-X during the time when the output head 32 moves by X.

In other words, the ratio of the distance traveled by the reading head 16 and the output head 32 per unit time in the sub-scanning direction is the magnification M. However, the control method differs depending on the size relationship between xl and X17M, and in the case of (Xi
-Xi /M) after controlling the reading head 16 to move independently, the reading head 16 and the output head 3
2 to move at the same time. In this way, when the reading head 16 comes to the start position, the output head 32 is also at the start position SP, and synchronization in the sub-scanning direction can be achieved. In addition, in the case of (Xl-M-x,
), and then the reading head 16 and the output head 32 are moved simultaneously.

On the other hand, management of input and output image information in the main scanning direction is performed as follows. As shown in FIG. 17(A), @, the point P (xl, y, ) is set as the point closest to the origin of the circumscribed rectangle of the figure to be imaged on the input drum 10, and the image is normalized to a predetermined unit of pixels. expressed by relative coordinates. Then, a point Q (XI, Yl) corresponding to the point P is expressed by absolute coordinates normalized to a predetermined unit of pixels above the output drum head. In this way, the pixel points of the input/output image can be represented by the lattice points shown in FIGS. 17(5) and (B). After the density pixel data converted into digital quantities by the AD converter 41 is processed by the signal processing circuit 42, the address register in the Y direction of the input drum 10 is
From the time it reaches lJ, the start point and end point are sequentially stored in the buffer memory 43 at incremented timings. In addition, when using the buffer memory 43 in output mode, it is valid from the point when the address register becomes "Yl" in the Y direction, and the starting point is Y, with Yl as the origin.
Control is performed to output pixel 1 from the ramie to the end point YB. Note that the buffer memory 43
There are two series for each line, and when one is used in input mode, the other becomes output mode. Therefore, the output image is output with a delay of one line compared to the input image.

In the above-described embodiment, there are four types of input original images A to D, but the shape and number of input original images are arbitrary, and the layout of the output image can also be input in any shape. In addition, although color correction and gradation conversion are performed digitally in the above, they can also be performed analogously, and manual image reading and layout image output are performed on a flat surface rather than on a cylindrical drum. A scanning type scanner is also possible. Sara K
.

The output image may be a color image, a monochrome image, or a halftone image using a line processing circuit and a reduction control circuit, and the recording material may be a color positive film or a monochrome film. Furthermore, although the magnification of the above-described output is controlled by changing the scanning speed at the input end, it is also possible to change the scanning interval at the output side.

In the above, +i which is AD converted by the AD converter 41
The AI image signal is color-processed by the color processing circuit 42, and the color-processed signal is stored in the memory 43. However, the AD-converted image signal is stored in the memory, and the color processing circuit performs the color processing at the time of output. Color processing may also be performed.

As described in detail above, the method for positioning N input images of the present invention is to paste the original image to be input onto a transparent paste, provide register pin holes in the transparent paste, and provide register pins in the input drum and digitizer. Since this is done by engaging the pin and the pin hole, it is possible to easily and accurately associate the coordinates of the input original image on the input drum with the coordinates on the digitizer, making coordinate management easy. It has the advantage of being

T, c. In the above, two register pin holes are provided on the upper side of the transparent page, but the position and shape of the pin holes are arbitrary, and the number and shape of the pin holes are arbitrary. It would be better to provide a pin. Furthermore, the pace does not necessarily have to be transparent (it is also possible), as long as the pace original input and the image input are performed.
