Abstract

PURPOSE:To avoid the magnification processing from being limited by the paper size of an output device by dividing a picture by one pattern stored in a picture storage memory into plural prescribed areas and forming the plural split areas onto a different recording member. CONSTITUTION:When a magnification consecutive photographing command is received from a host computer, a CPU 22 calculates a split size of a memory from the paper size and the magnification and sets the result to a system controller and a readout counter 0. A readout counter calculates the head address of the succeeding line when the readout is finished, repeats the readout again and reads out the signal till the line (b) and the 2nd print is finished. Succeedingly, the head address 2 of the 1st page is calculated till the 2nd 1TOP signal 551 reaches and while the head address is repetitively calculated and the originals are printed consecutively up to the 4th page. Finally, printed pictures are jointed to obtain the picture subject to magnification processing.

The film scanner 34 is a device that converts a 35 mm film (positive/negative) into electrical color image information using a photoelectric converter such as a CCD. The details of each part will be explained below. Description of Color Reader 1> First, the configuration of the color reader 1 will be described. In the color reader l shown in FIG. 1, 999 is an original, 4 is a platen glass on which the original is placed, and 5 is a halogen exposure lamp 10 that collects reflected light from the original that has been exposed and scanned, and a 1-magnification full color sensor. This is a rod array lens for inputting images to 6. The rod array lens 5, the same-magnification full-color sensor 6, the sensor output signal amplification circuit 7, and the halogen exposure lamp 10 together constitute a document scanning unit 11, which scans a document 99.
9 is exposed and scanned in the direction of the arrow (AI). The image information to be read from the original document 999 is sequentially read for every l line by exposing and scanning the original scanning unit 11. The read color separated image signal is amplified to a predetermined voltage by the sensor output signal amplification circuit 7, and then input to the video processing unit via the signal line 501, where the signal is processed. Note that the signal line 501 has a coaxial cable configuration to ensure faithful signal transmission. A signal 502 is a signal line that supplies a drive pulse for the full-color sensor 6,
All necessary drive pulses are generated within the video processing unit 12. Reference numerals 8 and 9 denote a white plate and a black plate for white level correction and black level correction of the image signal, and by irradiating them with a halogen exposure lamp 1O, a signal level of a predetermined density can be obtained, respectively, and the video signal. White level correction. Used for black level correction. 13 is the color reader of this embodiment which has a microcomputer! This is a control unit in charge of overall control, and performs display on the operation panel 20, manual key control, control of the video processing unit 12, etc. via the bus 508. Further, the position of the document scanning unit 11 is detected by position sensors Sl and S2 via signal lines 509 and 510. Furthermore, the stepping motor drive circuit 15 that pulse-drives the stepping motor 14 for moving the scanning body 11 is connected to the halogen exposure lamp 10 by the exposure lamp driver 21 via the signal line 504.
Color league unit 1 that controls N10FF, light amount control, and controls the digitizer 16 and display unit via the signal line 505.
All controls are in place. Further, 20 is an operation section of the color league section 1, which includes a liquid crystal display panel that also serves as a touch panel and keys for giving various instructions. Note that display examples of such a display panel are shown in FIG. 47 and subsequent figures. The color image signal read by the above-mentioned original scanning unit 11 during original exposure scanning is sent to the sensor output signal circuit 7. The signal is input to the video processing unit 12 via a signal line 501. Next, details of the document scanning unit 11.degree. video processing unit 12 described above will be explained using FIG. The color image signal input to the video processing unit 12 is separated into three colors, G (green), B (blue), and R (red), by the sample and hold circuit S/H 43. Each separated color image signal is converted from analog to digital by an A/D converter 44 to become a digital color image signal. In this embodiment, the color reading sensor 6 in the document scanning unit 1-11 is arranged in a staggered manner divided into five areas, as also shown in FIG. Using this color reading sensor 6 and the misalignment correction circuit 45, the 2nd and 4th channels being pre-scanned and the remaining 1st and 3rd channels are scanned in advance. The reading position deviation of 5 channels is corrected. The positional deviation corrected signal from the deviation correction circuit 45 is input to the black correction circuit/white correction circuit 46, and color reading is performed using signals corresponding to the reflected light from the white board 8 and the black board 9 described above. Darkness unevenness of sensor 6,
Non-uniformities in the light amount of the halogen exposure lamp 10, variations in sensor sensitivity, etc. are corrected. Color image data proportional to the input light amount of the color reading sensor 6 is input to the video interface 201 and connected to the image storage device 3. This video interface 201 has the functions shown in FIGS. 3 to 6. That is, (1) black correction/

connection. In particular, the CPU communication line is connected to a communication controller 162 within the control unit 13, and exchanges various commands and area information. It has five functions. These five functions are selected by the CPU.
The control line 508 switches as shown in FIGS. 3-6. As explained above, the video interface 201 has five functions, including signal lines 205, 206, .
207 is capable of bidirectional transmission. This configuration enables bidirectional transmission, reduces the number of signal lines (and makes the cable thinner and cheaper. Also, the interface connector of the image storage device 3 connected to the color reader l (see Fig. 27) (A) 4550) signal line is also capable of bidirectional transmission. Therefore, the number of connection lines between each device composing the system can be reduced, and furthermore, high-level communication between each other can be achieved. Further, the image information 559 from the black correction/white correction circuit 46 is input to a logarithmic conversion circuit 48 (FIG. 2) that performs processing to match the luminous efficiency characteristics of the human eye. Here, white = 00H, black = FFI (converted as much as possible, and image sources input to the image reading sensor, such as a normal reflective original and a film projector).
Transparent originals such as , and even the same transparent original have different gamma characteristics input depending on negative film, positive film, film sensitivity, and exposure status.
As shown in (b), the LUT for logarithmic transformation (
It has multiple lookup tables (lookup tables) and uses them depending on the purpose. Switching is done using signal line I! go, f gl,
I! g2, and the I10 port of the CPU 22, by inputting an instruction from an operation unit or the like. Here, the data output for each B, G, and H corresponds to the density value of the output image, and the data output for each B (blue), G (green), and R (red) signal is Since this corresponds to the toner amounts of yellow and magenta cyan, the color image data after this point is associated with Y, M, and C. Note that the color conversion circuit 47 is a circuit that detects a specific color from the input color image data R, B, and G and replaces it with another color. For example, it realizes a function of converting a red part of a document into blue or any other arbitrary color. Next, each color component image data from the original image obtained by logarithmic transformation 48, that is, the yellow component. The color correction circuit 49 performs color correction on the magenta and cyan components as described below. The spectral characteristics of the color separation filter arranged for each pixel on the color reading sensor are as shown in Figure 8 (it has unnecessary transparent areas such as the shaded area; color toner (
It is well known that Y, M, C) also have unnecessary absorption components as shown in FIG. Note that the figure only shows R, G, Y, and M, respectively. Therefore, masking correction is well known in which color correction is performed by calculating a linear equation for each color for each color component image data Yi, Mi, and Ci. Furthermore, by Yi, Mi, Ci, Min (Yi, Mi, Ci) (Yi, M
(minimum value of i, Ci), set it as a smear (black), and then add black toner (smear insertion);
An under color removal (UCR) operation is also often performed in which the amount of each coloring material added is reduced depending on the added black component. In Figure 10(a),
The circuit configuration of a color correction circuit 49 that performs masking, smearing, and OCR is shown. The characteristics of this configuration are: ■ It has two masking matrices, and can be switched at high speed with one signal line "110." ■ One signal line "110" indicates whether UCR is present or not. Can be switched at high speed. 1) There are two circuits for determining the amount of smear, and "Ilo" can be switched at high speed. First, prior to image reading, a desired first matrix coefficient M3. A second matrix coefficient M2 is set via a bus connected to the CPU 22. In this example, M is set in registers 50-52, and M2 is set in registers 53-55. Further, 56 to 62 are selectors, respectively, which select A when the S terminal is "B" and select B when the S terminal is "0". Therefore, when selecting the matrix M, the switching signal MARE

In addition, 63 is a selector, and selection signals C8°C, (
567, 568), outputs a, b, and c are obtained based on the truth table shown in FIG. 10(b). Selection signal C

0°1, 0), (1, 0, O), and then (0, 1, 1) as a monochrome signal to obtain a desired color-corrected color signal. Note that CGI C1+c is executed by the CPU 22 according to the image forming sequence of the color printer 2.

The outputs (a, b, c) of the selector 63 contain the contents of the registers 50a, 50b, 50c, and therefore (ay+

It undergoes the -order transformation ax-b (a, b is a constant) and is input (through the selector 60) to the B inputs of the subtracters 65a, 65b, and 65c. Each subtractor 65a, b, c removes the undercolor by Y = Y i - (ak - b), M
= M i −(ak − b ). C=C1-(ak-b) is calculated, and the signal line 571a. The signals are inputted via 571b and 571c to multipliers 66a, 66b, and 66c for masking operations. Selector 60 is controlled by signal UAREA572 and UAR
EA572 has UCR (undercolor removal), with and without “I”.
The multipliers 66a, 66b, and 66c each have eight inputs (ayl, -bMt, -Cct),
The B input has the above-mentioned (Yi-(ak-b), Mi-(a

As is clear from the figure, the output Dout has the condition of C2=0 (Y or

Mix(-bM3)+Ci X(CC3) is output to Dout. Color selection is done by (CO+ 01 + C2) according to the order of output to the color printer.
It is controlled by the CPU 22 according to the table in FIG. 0(b). Registers 67a, b, c, 68a. b and c are registers for monochrome image formation, and based on the same principle as the above-mentioned masking color correction, MONO=

It is configured. Therefore, this configuration can be applied when images obtained from image input sources having different color separation characteristics or a plurality of images having different black tones are combined as in this embodiment. Note that these area signals MAREA, UARE
A, KAREA (566°572, 573) are generated by an area generation circuit (69 in FIG. 2) which will be described later. Next, a black character processing circuit for reproducing black characters and thin lines in a document and improving color bleeding at the edges of black characters and black lines will be described with reference to FIGS. 11 and 12. The black level/white correction circuit 46 shown in FIG.
R, G, B (red, green, blue) color signals 559R, 559G with white level correction. 559B is LOG conversion 48, masking, under color removal 49
After receiving the color signal, the color signal to be output to the printer is selected and output to the signal line 565. In parallel with this, the signal R
, G, and B. In order to detect the achromatic and edge portions of the document (i.e., black characters, black thin lines), the luminance signal Y1, the color difference signal 1. Q is calculated by a Y, I, Q calculating circuit 70 (FIG. 11). The luminance signal Y575 is used to extract the edge signal (
A line buffer circuit 7 for 5 lines is used to calculate a 5×5 matrix using a known digital second-order differential circuit 72.
1, and the Laplacian operation is performed in the arithmetic circuit 72 as described above. That is, when the input luminance signal Y is a step-like input (for example, a character part) as shown in i) of FIG. signal). The look-up tables LUTA73a and LUTB73b are look-up tables for determining the printing m (for example, toner ■) at the edge portion of black characters (or thin black lines), and are as shown in FIGS. 12(a) and 12(b), respectively. It consists of a lookup table with characteristics. That is, when LUTA acts on the edge signal 576, the amplitude increases as shown in FIG. 12(d)(iii), and this determines the amount of black toner at the black edge portion, as will be described later. Furthermore, when LUTB acts on the edge signal 576, the absolute value appears negative, which is due to the Y
, M, C (yellow magenta, cyan) toner amounts are determined. This is a signal as shown in FIG. 12(d) (iV), and when it passes through the smoothing (averaging) circuit 74, it becomes a signal as shown in FIG. 12(V). On the other hand, the achromatic color detection circuit 75 outputs, for example, the 12th
This is a circuit that outputs a signal according to the characteristics shown in the figure, and this signal is selected by the selector 76 during black toner printing by the signal 577 which becomes "1" when printing black toner, and the signal 577 becomes "1" when printing black toner.
78 and is multiplied by the aforementioned signal 579 (FIG. 12(d) (iii)) which determines the amount of black toner in a multiplier 77, and then added to the original image signal in an adder 78. . On the other hand, when printing with Y, M, and C (yellow, magenta, and red) toners, it is desirable that the Y, M, and C toners not be printed on black characters and black line areas, so the color selection signal 577 The selector 76 outputs "l" to the multiplier, and the selector 79 outputs a signal obtained by smoothing the output from the LUTB 736 (Fig. 12(d) (V)
) is output, and the same signal as in FIGS. 12(d) and (V) is input to the adder 78, and the signal only from the black edge portion is subtracted from the original signal. In other words, this means that the signal that determines the amount of black toner for the black edge area is strong (in other words, by increasing the amount of black toner and decreasing the amount of Y, M, and C toners for the same area, The signal 581 obtained by binarizing the achromatic signal 580 by the binarizing circuit 80b becomes "1" when the color is achromatic and "0" when the color is chromatic. As shown, in the selector 79, when printing with black toner (577-“I”) S input = “l”
Then, A input, that is, 579 (Fig. 12(d) (i
ii)) is output and the black edges are emphasized. Y, M,
When printing with C toner (when 577="0"), the signal 581-

The signal of ii) is output to adder 78 and results in the usual well-known edge enhancement. The LUTA 73a has a LUT and ±
Two types of LUTs are prepared so that the value becomes zero at m or less, and the value to be clamped to zero is selected depending on the level of the original signal 565, that is, the density of the document at this point. When the density level of the original is higher than the value set by the CPU 22 via the bus 508, that is, when it is dark, the output of the comparator 81 becomes "1", and the 12th
The LUT clamped to zero at A'B' in figure (a) is
Furthermore, when the concentration is below a certain level, that is, when the output of the comparator 81 is "O", the LU is clamped to zero at A and B.
By selecting T, the noise removal effect is changed depending on the density range. Furthermore, the output 583 of the AND gate 82 is obtained by further improving the edges of black characters, and when printing Y, M, and C, the output 583 (B
This is a signal for switching to select 585 for other inputs. Signal 5 input to AND gate 584

) is binarized by the binarization circuit 80a, that is, when the absolute value of the edge signal is above a predetermined value, it becomes "l", and when it is below, it becomes mO#. Therefore,
587="1"581="1",588="L" is achromatic color and when the edge signal is large, that is, at the edge of the black signal, and at the edge of Y, M, and C. Only when printing with toner. Therefore, at this time, as explained earlier, only the parts corresponding to the black edges from the original signal are Y and M. The signal determining the amount of toner C is subtracted, and the remaining signal is smoothed by the averaging circuit 84, and when the signal ER="1" is outputted to the selector 83 through the selector 83. Otherwise, the normal edge-enhanced signal 585 is output at output 589. The signal ER is controlled by the CPU 22, and when ER="1", the output of the averaging circuit 84 becomes the output 589, and ER=10.
When m, 0'' is output to the output 589. This means that the signal of the color toner (Y, M, C) around the edge of the black character is completely turned to "O" to further eliminate the color blur. These have a selectable configuration. FIG. 13 shows area signal generation in the area generation circuit 69 (
The aforementioned MAREA566, UAREA572. KARE
A573, etc.). The area refers to, for example, the shaded area in FIG.
Timing chart AR in Figure 13(e) for each YNC
It is distinguished from other areas by a signal such as EA. Note that this area is specified by, for example, the digitizer 16 or the like. FIGS. 13(a) to 13(d') show a configuration in which the number of generation positions, two interval lengths, and one interval of this area signal can be programmably obtained by the CPU 22, and in addition, a large number can be obtained. In this configuration, one area signal is a RAM that can be accessed by the CPU.
For example, n area signals AR
To obtain EAO~AREAn, RA with n bit configuration
It has two M (Fig. 13(d) 85A, 85B)
. Now, the area signal AREAO as shown in FIG. 13(b). and AREAn, the RAM address X
Bit O of lyx3 is set to "1", and all bits O of the remaining addresses are set to "0". On the other hand, RAM
The address LXI+x2+x4 is set to 1", and all bits n of other addresses are set to 0". H
RAM is synchronized with a constant clock using SYNC as a reference.
For example, as shown in FIG. 13(c), data "1" is read out at addresses X1 and X3. d) Flip-flop J is connected to J- of 86-0 to 86-n.Since it is connected to both K terminals, the output is toggled, that is, when "l" is read from RAM and CL K is input. , the output changes from "O" to "l" and from "l" to "0", and a section signal such as AREAO, and therefore an area signal, is generated.Also, the data = "0" across all addresses. Then, no area section is generated and no area setting is performed. Fig. 13(d) shows this circuit configuration, and 85A and 85B are the aforementioned RAMs. This is because the area section can be switched at high speed. For example, while reading data line by line from the RAM 35A, the CPU 22 performs a memory write operation for setting a different area to the RAM 885B, and alternately generates a section and writes data to the RAM 885B.
Switch memory writing from PU. Therefore, the first

Interval signals from REAO to AREAn are generated. During this time, writing from the CPU to B is via address bus A-
Bus, data bus D-Bus, and access signal R
/W is used. Conversely, when generating section signals based on data set in RAMA35A (c3.C4e
By setting Cs) = (L O+ 1), the same operation can be performed and data can be written from the CPU to the RAM 35A. Therefore, for example, image processing such as image cropping, frame removal, etc. can be easily performed based on this area signal. That is, the area signal 590 generated by the area generation circuit 69 in FIG. 2 as described above is I10.
Area switching signal ECH591 output from port 25
is selected by the selector 89, and the AND gate 9

If 0 is formed, the image is cut out from Xl to X3, and if it is formed like AREAn, it is cut out from xl to
The space between 2 and 2 is blank, 1 to XI+ X2 to X4
It will be easily understood that the image is cut out in the section up to. FIGS. 14 and 15 show the configuration and control timing of the area restriction mask bitmap memory 91. As can be understood from FIG. 2, for example, by using the detection output 592 of the color conversion circuit, which will be described later, it is possible to create an area restriction mask that limits the area only to a specific color area in the document.

3, a region control mask corresponding to the density value (or signal level) can be created. FIG. 14(a) is a block diagram showing details of the area restriction mask bitmap memory 91 and its control. As shown in Fig. 15, the mask is constructed so that 4 x 4 pixels constitute one block, and one bit of the bitmap memory corresponds to one block.

It is determined whether the number of 1's in the block of 4 is greater than a predetermined number. In FIG. 14(d), the number of 1's in block N is '14' and the number of 1's in block (N+1) is '4', so the output of comparator 97 in FIG. 14(a) 59
7 is "1" when the signal 597 is 14" and "0" when it is 4"
Therefore, the latch pulse 598 in FIG. 14(d)
Therefore, the latch 98 latches one 4×4 block once, and the Q output of the latch 98 is connected to the DIN input of the memory 99.
In other words, it becomes mask creation data. 100H is an H address counter that generates an address in the main scanning direction of the mask memory, and since one address is assigned to a 4×4 block, the pixel clock VCLK is divided by the frequency divider 101H.
Counting up is performed using a clock whose frequency is divided by four. Similarly, 1OOV is an address counter that generates the address in the sub-scanning direction of the mask memory, and for the same reason, the synchronization signal HSYNC of each line is controlled by the frequency divider 101V.

．． 600 is NOR'd by a NOR gate 102, a signal 602 is generated to gate the clock 601 of frequency divided by 4, and the signal 602 is gated by the AND gate 103 to obtain the first signal in the timing chart.
A latch signal 598 is generated as shown in FIG. Similarly, 604 is an address bus,
A signal 605 is a write pulse WR from the CPU 22. During WR (write) operation from the CPU 22 to the memory 99, the write pulse becomes "LO" (game) 104,1

The data bus is connected to the memory 99, and predetermined data is written at random, and WR (write) is performed sequentially by the H address counter and ■address counter.

Once a mask as shown in the figure is formed, images can be cut out, synthesized, etc. based on the area within the bold line frame. Next, the mask created in 4x4 pixel block units is
As shown in (i) of FIG. 17(b), the edge portion (boundary portion) is jagged in units of four pixels, so the interpolation circuit 109 in FIG. 2 smooths out the jagged portion and makes it look smooth. do. FIG. 17(a) shows a block diagram of the interpolation circuit. 110 is a selector, the input to which is a Hi clamp, that is,
If it is 8 bits, the FF is inputted to GND, that is, 00H, to the B input, and either one is switched by the output 606 of the bit map mask memory mentioned above. As a result, the interpolation circuit 111 outputs FFH within the area mask and OOH within the area mask. This is as shown in (i) in FIG. 17(b).
Any circuit such as the interpolation method may be used (and a well-known circuit configuration may be used. Since the output of the interpolation circuit is multi-valued, it is binarized by the binarization circuit 112. As a result, as shown in (ii) of FIG. 17(b), the smoothness of the boundary is ensured by changing the original boundary A to B.The selector 113 accepts the output of the mask memory as it is. The switching signal 608 connected to the I10 port of the CPU 22 switches as necessary whether to output (select A) or to select and output a mask signal with smooth boundaries after interpolation as described above. Therefore, for example, if the interpolation output is selected using the signal 608, and the ECH is switched to select the area restriction mask output using the selector 89 in FIG.
Therefore, it is only possible to cut out a non-rectangular figure using a mask as shown in FIG. 18(a). Also, the output of the mask memory of the bitmap memory 91 is connected to the signal line 607 in FIG.
When the signals are taken out from the above, selected by the selector 114, and synthesized by the synthesis circuit 115 described later, the result is as shown in FIG. 18(b). Reference numeral 116 in FIG. 2 is a density conversion circuit, for example, as shown in FIG. As shown in Figure 20 (F

16 is manually read out in the order of →1 → 2 → 3 → 4 → machining → 2 → 3 → l → 2 → 3''. In other words, Repeat
By applying the signal 616 to the FIFO, it is possible to repeat the same image as shown in FIG. 4(c). Therefore, a dotted line (cut line) is formed by writing the data of "B" as shown in FIG. As mentioned above, the image is repeated by the repeat circuit 118.
If the area generation circuit 69 controls the t signal so that it is generated at the points ■ and ■ in FIG. 21(A), a cutting line can be added to the repeated image, and as shown in FIG. 21(B).
By writing the “l” data like this, the four lines become (
By writing as in C), it becomes possible to form black frames on the image. The image signal 612 output from the repetition circuit 118 is input to the image synthesis circuit 115 and various image processing is performed thereon. <Synthesis> Next, the details of the synthesis circuit will be explained using FIG. 25(A), although the figure numbers are different. The editing process performed here is performed independently for each specified area.
This is performed programmably based on data set in the RAMs 135 and 136 shown in FIG. That is, the area code generator 13 will be described in detail later.
Code number obtained from 0 (hereinafter referred to as area code)
Each is processed separately. Digitizer 1 is used to specify the above areas and specify various editing processes.
6. In response to instructions (commands) obtained from the operation unit 20 and the image storage device 3, the area code generator 130 and RAM shown in FIG.
Parameters corresponding to the editing process are set in registers 135, 136 and registers 140-142. Further, in FIG. 25(A), 132 is a selector that selects the output of either the area code generation circuit 130 or the register 131. Note that 130 is an area code generator that automatically generates an area code in response to the synchronization signals H5YNC and CL-K, and register 131 is the CPU bus 50.
This is a register into which the signal from 8 is input. 135, 13
6 is an RA in which an area code and processing or image data corresponding to the area code are stored as a table.
It is M. As shown in FIG. 25(F), the contents of the tables in the RAM 135 and 136 include a code input as an input address through the selector 132, a code Co indicating the formed color when the printer is forming images sequentially, and C, and has a 3-bit function code and 8-bit data as its output. Note that this 3-bit function code is sent to the decoder 1 via the selector 137.
46. As described later, such a function code is, for example, a code for giving an instruction to add on characters or mask a specific image area, and the 8-bit data is, for example, data for adjusting the density of the image signal 612. 139°143.145 are the decoder output S
o, SL, S2゜S3. This is a selector whose selection state is changed according to S4, and 144 is a multiplier that multiplies the outputs of selectors 143 and 145. 1
46 is the most significant bit MSB 621 of the 6-bit data manually input via the selector 132 (The MSB is generated as an area code so that it becomes "1" at the end of each area of the image, as shown in FIG. 25(E)). ), the signal 613 . This is a decoder that decodes three characters: a character signal indicated by 614 and a function code inputted via the selector 137. Next, the above-mentioned area code will be explained. For example, as shown in Figure 25 (B), the area code is
When areas 148 are specified using the digitizer 16 or the like, a number, ie, an area code, is assigned to each area to distinguish each area. In this embodiment, the entire area of the document is assigned the area code "0" as shown in FIG. 25(B).
In this example, a rectangular area with diagonal lines at points a and b is set as area code "l," and a rectangular area with diagonal lines at points c and d is set as area code "2." For example, when scanning the section A-B shown in the figure, an area code is generated simultaneously with the scanning at the timing shown in the figure below. The same applies to the CD and EF sections. In this way, an area code is generated at the same time as the original is scanned,
The area code is used to distinguish between areas and perform different image processing and editing for each area in real time. The above settings are performed using the digitizer 16 and the operation unit 20 as described above. The number of areas that can be set is determined by the number of bits of the area code. For example, if it is n bits, it is possible to set a 2" area. Next, FIG. 25 (C) and FIG. 25 (A) 130 show. An example of a schematic internal configuration diagram of an area code generation circuit is shown.The generation circuit 130 is a circuit that generates the above-mentioned area code in real time simultaneously with the operation of a document, and uses the coordinates of the area obtained by the area specifying means such as the digitizer and By setting the area code, the area code is programmably generated.The details will be explained below.The RAMs 153 and 154 are memories each having a 7-bit word structure and a capacity for 1 main scanning line. This RAM has CPU address bus 627, data bus 6
25, it is connected to the CPU. 149 generates a RAM address by counting Video CLK with an address counter. Further, the counter 149 is reset by H3YNC, and the same address is sent to the selector 151 every time a new line is scanned.
, 152 to the RAM 153 . Give to 154. Therefore, in response to the reset, the RAMs 153 and 154 read data from the start. 155 is an interrupt generator which generates an interrupt signal INT to the CPU when it counts H3YNC which is input by the pre-programmed number from the CPU by the CPU data bus 625 and chip select 624, and also generates an interrupt signal INT to J-. RAM read by address counter 149 by toggle operation
are also switching. 151.152° 156 is a selector which selects either the A or B input based on the output of the flip-flop 158, thereby selecting the RAM 153, 15.
Select one of 4. FIG. 25(D) shows the RAM 153. 154 is an explanatory diagram showing the data structure of No. 154. MS 81 b i as shown
t and the lower 6 bits, the MSB represents the change point between the designated area and the unspecified area as described above, and the lower 6 bits store the changing area code. The address of the RAM corresponds to the Y coordinate which is the main scanning direction. FIG. 25(D) shows, for example, a designated area 159 (area code "20") on the document 150 shown in FIG. 25(E).
) represents RAM data when scanning between A-8. At this time, the area code for the entire area of the document is set to "0". The reversely set area has the area code “20”
This is an example when . Set the RAM with the above settings to the 25th
(C) The RAMs 153 and 154 are read out sequentially from the address generated from the address counter 149 to generate an area code. For example, when scanning the section shown in FIG.
(Area code “0”) is read out, as shown in Figure 25 (C).
As shown in FIG.
0" is output. Also, when the point a(0, P) is reached, the RAM output is MSB "l", and the lower 6b is "20
” is read out and latched as above, and the area code “2” is read out.
0" is output. The address advances further and the area code "20" is output until the next MSB becomes "l". In other words, address r is read and data is newly latched as described above. The area code "20" continues to be output from the latch 157 until the area code "20" continues to be output from the latch 157. The scanning progresses further, and when the main scanning in the Y direction is completed, it advances by one in the X direction and H8YNC is counted by the interrupt generator 155. At this time, as described above, The address counter 149 is reset and the read address starts from 0 again. Also, since the area is rectangular, the same data, i.e. Either one of the RAMs 153 and 154 can be read continuously, and if the count number of the
When the scanning from -B to section C-D is completed, the interrupt generator 155 generates an interrupt signal INT, and at the same time, the interrupt signal INT is read out by the selector 156 by the toggle operation of the flip-flop 158 in FIG. R.A.
M is switched. As a result, the next area information programmed in advance is output from the RAM selected by the selector 156. In addition, when the interrupt JNT occurs, the CPU uses the coordinates and area code of the area obtained by the above-mentioned means to send a new and different data to the interrupt generator 155 and also to the idle RAM, that is, the RAM that has not been selected by the selector 156. Set the signal according to the specified area. This setting is performed under the control of the data bus 625 and chip select signals C2 and C3 from the CPU. The area code 626 can be generated for the entire screen of the document with a small memory capacity by using the above-mentioned configuration, that is, by sequentially switching the two RAMs and programming the idle RAM by the CI'U. As mentioned above, the area code 626 output from the area code generation circuit 130 shown in FIG. 25(A) is input to the selector 132 together with the image signal, and editing processing is performed for each area based on the area code. . The area code generator 130 was able to generate area codes only for rectangular areas, but in this embodiment, it is configured to be able to generate area codes for non-rectangular areas as well. 131 and 132 are provided for this configuration. Reference numeral 131 shown in FIG. 25(A) is a register connected to the CPU bus 508. An area code corresponding to a non-rectangular area is set in this register in advance. At this time, as will be described later, when a non-rectangular area signal 615 from the image storage device 3 is input, the value set in the register 131 is selected by the selector 132 using the signal 615 as a select signal, and the non-rectangular area signal You can now obtain a non-rectangular area code that supports . As mentioned above, the area code is 6 bits in this embodiment.
Yes, MS8621 1 bit is input to decoder 146 and selector 137, other signals are input to RAM 13
5.136 is input in parallel. The RAMs 135 and 136 are connected to the CPU bus (data bus 62
5. CP by 508 (generally refers to address bus 627)
It is connected to U and has a programmable configuration. FIG. 25(F) shows RAM 135. 136 data structure is shown. Reference numeral 133 is a schematic diagram of the configuration of the RAM, in which a 4-bit area code and a color select signal 6 are input as address inputs.
29.2 bits, a total of 6 bits, are input. At this time, the color select signal C6+CI+C2 is 2 bitsCo from LSB! By using CI, it is possible to select which of the four colors the image signal sent in frame sequence is, and thereby change the address to be accessed for each area code (black). In this embodiment, M (magenta), C (cyan), and Y (yellow) are used for each primary color to be used for image formation by the printer 2, as will be described later.
, Bk (black) images are transferred in sequential order. At this time, the type of color to be transferred is determined by color select 629 signals C6 and C1 shown in FIG. 25(A) (same signals as C8 and C1 shown in FIG. 1O(a)). A detailed data structure diagram is shown at 134 in FIG. 25(F). As shown in the figure, the 3 bits from the MSB have a function code, and by decoding this code, different image processing is performed according to the code. In this embodiment, by representing the function code with 3 bits, six types of image editing are possible for each area code or color. The lower 8 bits store various parameters during image processing and editing according to the function code. The data selected from the area code and color select signal is 3 btt from MSB, that is, the function code is the second
Input to the selector 137 shown in FIG. 5 (A) 137,
Two RAs with area code MSB 621
The 3-bit function code output from M is switched. On the other hand, the lower 8 bits of data are also sent to the decoder 146.
It is selected and output to the selector 139 by the select signal Sl from the selector 139. The selected function code is input to the decoder 146 and output as a character signal 622, as well as an area code M S B b
Together with the i t 621, a control signal 623 for each editing process is generated. Each control signal is used as a selector selection signal and editing is performed by changing the signal flow. In this embodiment, the following six editing functions are realized using the control signals. (2) In-area through designation Within the area, the function outputs the image signal without performing any processing. The input image signal passes through a negative/positive inversion circuit (described later) shown at 138, is selectively output from the selector 143 at S2, and is input to the multiplier 144. On the other hand, one of the RAM data is selected from the selector 139 by Sl, and then S3. It passes through a selector 145 determined by S4, is operated on the image signal by a multiplier 144, and is output. At this time, multiplier 1
The density of the image is determined from the RAM data input to 44, and the density and color balance can be varied independently for each area by setting a different count for each color sent in frame sequence. That is, when the user sets the color balance of the area after setting the area using the operation panel, the CPU transfers the setting value to the RAM 135 or R via the bus 508.
Write to AM136. Furthermore, the B input of the selector 145 may be selected and multiplied by the image signal 612 by the multiplier 144. ■Intra-area masking This function outputs an image that is uniformly filled with any other color over the entire designated area. For example, when scanning a certain area with this function set, S2
RAM data is selected instead of the image signal and input to the multiplier 144. On the other hand, the coefficient is the control signal S3.
Select the register 142 from S4, and although it is not shown in the figure, it is connected to the CPU by a bus and the CPU
A more suitable coefficient such as “1” is stored (multiplier 1
44 and output. ■Insertion of characters within the area (1) For example, as shown in Figure 25 (G), the specified area 1 of the image
This is a mode for inserting characters as shown in 160 into 59. For example, as shown at 161, character data is stored in a bitmap memory or the like in advance. At the same time as the specified area is scanned, the binary data of the character is scanned and read out from the memory at the timing shown in the figure, and the character signal 62 is generated.
Set it to 2. This signal is input as a character signal shown at 622 in FIG. 25(A), and the selector 143 is switched. That is, when the character signal 622 is High, the selector 143 selects the data in the RAM 135 or 136, and when it is Low, the selector 143 selects the image signal.
The decoder 146 performs the insertion by outputting -84. In addition to the above character signal, 33. S4 also changes, and the coefficient of the multiplier 144 selects register +40 when the character signal 622 is High. This is also connected to the CPU bus as described above, and appropriate coefficients are set in advance. Normally, the register 140 is set to 1. In particular, by changing the coefficients set in the register 140, the density of inserted characters can be freely changed. ■ Insertion of characters within an area (2) A function to mask the inside of a specified area with a specified color as shown in Figure 25 (H), and to insert characters in the same area with another specified color as described above. It is. While scanning within the designated area, the selector 143 is in the R position as described above.
AM data is selected. As mentioned earlier, at this time,
The selector 139 is switched based on the character signal obtained from the bitmap memory shown in FIG. 25(G). That is, if the data is not a character, the data in the RAM 135 is output, and if it is a character, the data in the RAM 136 is selected. Incidentally, in the RAM 136, for example, density data of characters within the region, and in 135, density data of, for example, characters other than the characters within the region are written in advance via the CPU bus 508. Similarly to the above, coefficients as well as character signals are stored in the register 142. 140 is selectively output. The multiplier 144 calculates and outputs the result. That is, since the registers 140 and 142 are provided separately, the densities of the text area and the areas other than the literature area can be set independently. (2) Negative/Positive Reversal within Area This is a function to invert only the negative/positive image within the area and output it, and this is performed by switching the negative/positive inverting circuit 138 using the control signal SO. The output from 138 is output with the same settings as the through function. ■ Inserting negative/positive inverted characters within an area This is a combination of the above-mentioned intra-area character insertion function (1) and the above-mentioned intra-area negative/positive inversion, and is a function that inserts characters into negative/positive inverted images within an area. . The character insertion means is the same as the means described above, so a description thereof will be omitted. In the embodiment described above, the operation of the decoder 146 in FIG. 25(A) is shown in FIG. 25(1). 1 to 6 shown in the leftmost column in the map reading correspond to the above ■ to ■
It shows each function. Further, the left side indicated as "input" in the figure is the input of the decoder 146, and the right side indicated as "output" is the outputs SO to S4 of the decoder 146. The image information processed by the video processing unit 12 as described above is output to the color printer 2 via the printer interface 56. <Description of Color Printer 2> Next, the configuration of the color printer 2 will be described using FIG. 1.
