Abstract

PURPOSE:To allow an operator to automatically split a copy larger than a paper size into plural copies so as to transfer the copy by calculating the number of sheets from a detected original size and a specified magnification and displaying the number. CONSTITUTION:With the aid of TX=PX/MX and TY=PY/MY, the size of a trimming area is reversely calculated from the sizes PX and PY of paper sizes and magnifications MX and MY selected by the operator, and is set in the areas TX and TY of a RAM. Thus what the operator should do is only to set the original, the magnification and the paper conditions, and a CPU automatically calculates the number of sheets necessary for comprising outputs in the prescribed size and displays NX.NY on a sheet number display part before an image reading scan starts.

Description

[Detailed Description of the Invention] Since there is a limit to the size of the document (usually up to the equivalent of A3 size), even if an enlarged copy is made, only a portion of the document can be obtained as output. Furthermore, in order to paste the copy outputs together to make a copy larger than the maximum paper size, the operator had to change the placement direction and position of the document each time it was copied. In addition, the object is to provide an image processing device that can automatically divide copies larger than the paper size into multiple copies based on the magnification and output paper size, even though the overlapping width between copies and the output order are uncertain. shall be.

Figure 3 shows a system block diagram of the reader.

The CCD reading section 301 includes a COD, a clock driver for the COD, a signal amplifier from the COD, and an A/D converter for A/D converting the signal.

Image data converted into a 6-bit digital signal is output from the CCD reading section 301 and sent to the shading correction section 3.
02 is input.

After the shading correction unit 302 detects and corrects the shading amount of the light source, lens, etc., the image signal is automatically stored in the shift memory unit 303. 30
3 has a shift memory for two lines, and when the Nth line image data is being written into the first memory, the N-1th line image data is read from the second memory. In addition, a portion of the shift memory includes a write address counter for writing image data into the shift memory, a read address counter for reading image data, and an address selector circuit for switching address signals from these two counters. Details are shown in FIG. 9.

Further, the scaling/movement processing unit 304 performs scaling and movement in the main scanning direction by changing the clock at which the image signal is written to the shift memory, the clock at which the image signal is read from the shift memory, and the timing at which the image signal is read. These details will also be described later.

The image signal output from the shift memory is sent to the density processing section 30.
5, where it is subjected to binarization processing and dither processing.
It becomes a value number and is output to the "trimming" processing section 306.The trimming processing section 306 forcibly adds "O" or "1" to any section of the main scanning life image data, making it possible to edit the image. The details will be explained later.

The binary code output from the density processing section 305 is also input to the document position detection section 307. Here, the binary code is used to detect the positional coordinates of the document on the document platen glass by means described later.

The CPU section 308 includes a CPU, ROM, and RAM.

Consists of a timer circuit and an I10 interface. C
The PU unit 308 controls the operation unit 507, controls the reader according to settings from the operator, and also controls the printer through serial communication.

313 and 314 are position sensors for the CPU to know the position of the optical system. It is connected to the printer via connector JRI and printer connector JPI. Control signals necessary for image data communication and serial communication are exchanged between the reader and printer. Details will be described later using FIGS. 13 and 14. The horizontal synchronization signal BD from the printer is J
Clock generator 309
is input. A clock generator 309 generates a COD signal transfer microphone, a shift memory read/write clock, etc. in synchronization with the BD.

The circuit diagram of FIG. 4 shows the logic for detecting the coordinates.

The main scanning counter 351 is a down counter, and the main scanning counter 351 is a down counter.
This counter, which represents the scanning position in a line, is set to the maximum value in the main scanning direction (X direction) by the horizontal synchronizing signal H3YNC, and counts down every time the image data clock CLK is input. The sub-scanning counter 352 is an up counter that is reset to O'' at the rising edge of VSYNC (image leading edge signal), counts up in response to the HSYNC signal, and represents the scanning position in the sub-scanning direction.

The image data VIDEO that has been binarized by the previous scan is input to the shift register 301 in units of 8 bits. When the 8-bit input is completed, the gate circuit 302 checks whether all of the 8-bit data is a white image, and if YES, outputs 1 to the signal line 303. The F/F 304 is set when the first 8-bit white appears after scanning the original. This F/F is reset in advance by VSYNC. After that, it remains set until the legal VSYNC comes. Lunch F/F3 when F/F304 is set
05 is loaded with the value of the main scanning counter 351 at that time. This becomes the X1 coordinate value. Also, the value of the sub-scanning counter 350 at that time is loaded into the launch 306, and this is
It becomes 1 coordinate value. Therefore, P1 (Xl, Yl) is found.

Also, each time 1 is output to the signal 303, the main scanning counter 351
Load the value from into latch 307. The value from the main scanning counter when the first 8 bits of white appear is launch 3.
07, lunch 310 (this is VSYN
A comparator 309 compares the data with the data (set to the maximum value in the X direction at time C). If latch 3
If the data in latch 307 is smaller, the data in latch 307 is loaded into launch 310. Also, at this time, the value of the sub-scanning counter is loaded into the latch 311. This operation is as follows
The bits are processed until they enter shift register 301.

In this way, if the data of the latch 307 and the latch 310 are applied to the entire image area, the minimum value of the document area in the X direction remains in the latch 310, and the coordinate in the Y direction at this time is the latch 311.
will remain in the Since the main scanning counter 351 is a down counter, the coordinate corresponding to the minimum value in the X direction represents the coordinate farthest from SP in the main scanning direction, which is P3 (X
3, Y3)-c.

The F/F 312 is an F/F that is set for each main scanning line when 8-bit white appears for the first time, and receives the horizontal synchronization signal H3.
It is reset by YNC and the first 8 bits are set to white and held until the next H5YNC. At the time when the F/F 312 is set, the value of the main scanning counter corresponding to the position of the first white signal appearing in one line is set in the latch 313. Then, the latch 315 and the comparator 316 compare the magnitude. The minimum value 11011 in the X direction is set in the latch 315 at the time VSYNC occurs.

If the data in latch 315 is less than or equal to the data in latch 313, signal 317 becomes active and the data in latch 313 is loaded into latch 315. This operation is performed between H5YNC and H5YNC.

If the above comparison operation is performed for the entire image area, latch 3
15 remains the maximum value of the document coordinates in the X direction, that is, the X coordinate of the white signal of the point closest to the scanning start point in the main scanning direction.

This is x2. Also, when the signal line 317 outputs,
The value from the sub-scan is loaded into latch 318. This becomes Y2 and the P2 (X2°Y2) coordinate is obtained.

Each time 8-bit white appears in the entire image area, the latches 319 and 320 are loaded with the main scanning counter value and the sub-scanning counter value at that time. Therefore, when the document pre-scanning is completed, the count value at the time when 8-bit white appears last remains on the counter.

This is P4 (X4, Y4).

The above 8 latches (306, 311, 32031, 8
, 305, 310, 315, 319) are connected to the pass line BUS of the second mother CPU.
This data will be read at the end of the previous scan.

FIG. 9 shows a circuit diagram related to the shift memory. A write address counter 904 is an address counter when writing data to the shift memory 907, and a read address counter 905 is an address counter when reading data from the shift memory 907. It is a counter. The address selector 906 receives a command from the CPU via the I10 port 901 and selects either the address signal of the write address counter 904 or the address signal of the read address counter 905 to address the shift memory.

I10 registers 902, 903 are write address counters 904. These registers are used by the CPU to give preset values to the read address counters 905, respectively.

The write address counter 904 and the read address counter 905 are both down counters, and each receives a WST signal and an R3T signal that command the start of a counting operation, and also receives a write clock WCLK to the shift memory and a read clock RCLK from the shift memory. be done.

915.916 is an exclusive OR gate for determining the image area, OF is a signal that controls it, and when it is l, an ST counter 912.916 is used. Mask the area determined by the EN counter 913,
The area outside the frame is set as the output image, the area inside the 0 time frame is set as the output image, and the area outside the frame is masked.

910 is an AND gate that controls the output of the image data that is output from the shift memory and becomes a binary code after passing through the density processing unit 908; 917 is an AND gate that determines whether the masked portion described above is output as white or black. BB is a signal that controls it, and when it is 1, it outputs black, and when it is 0, it outputs white.

911 is an OR gate that outputs the image output from game) 910 and 917 as VIDEO, 909 is an exclusive OR gate that controls black and white and point control of image data, and IN is a signal that controls it; when it is 1, the image is the same as the original; 0
When , it makes you disagree. Each signal is output by the CPU according to the mode specified by the operator.

ST counter 912 and EN counter 913 each have 5 TARTs for outputting an image only to a predetermined area.
BIT C, 0 UNTER and END BIT
At C0UNTER, the CPU presets count data for the gate via Ilo. The flip-flop 914 is set when the ST counter 912 counts up and is reset when the EN counter 913 counts up. The operation is shown in FIG. 1O.

For example, in the case of the OF signal 1, when the Q of the F/F 914 becomes 1 as the ST counter 912 counts up, the output of the gate 915 becomes O, and the output of the gate 910 is masked until the EN counter 913 counts up. Instead, the output of the gate 916 is 1 during that time, so the BB times signal 1
When , the gate 917 is 1, the gate 911 outputs 1, and becomes a black mask.

Conversely, when OF=l and BB=0, self-masking is performed. Also, when 0F=O, the outputs of gates 915 and 916 each become 1.0 during that time, so when BB=1, the outside of trimming is black, and 0T=0. When BB=0, the area outside the trimming is white.

Next, the principle of variable magnification will be explained.

Magnification in the sub-scanning direction is performed by varying the scanning speed of the optical system. The CPU moves from the magnification specified by the operator to D.
Calculate the speed of the C servo motor and find the PL corresponding to that speed.
Calculate the L frequency and preset it in the motor driver shown in Fig. 3 311 before scanning.The conveyance speed of the printer is always 180 mm/sec, so when magnifying it twice, the station's speed is 180 mm/see at the same magnification. Speed 90mm/
Moves at sec, and when reduced to a station, doubles the speed to 360m
Move at m/sec.

The magnification change in the main scanning direction will be explained with reference to FIG.

A serial signal after A/D conversion from a CCD that is output at a constant frequency is sampled at a clock rate corresponding to the magnification.

When the size is the same, as shown in Figure 11-1, the data is written to the shift memory using the write clock WCLK, which is equal to the transfer lock CLK from the COD, and read out is equal to the output clock VCLK to the printer, as shown in Figure 11-2. Read from the shift memory using clock RCLK.

For example, when expanding and contracting, the write clock W to the shift memory
CLK is transferred as shown in Figure 11-3, and the original information written at the CLK station is sampled one beat at a time for 2 beats, and as shown in Figure 11-2, the output clock VCLK and the same read clock RCLK are read out and reduced. Realize.

Also, when enlarging to 2 times, when writing to the shift memory, write as shown in Figure 11-1, same as when magnifying the same, and when reading from the shift memory, output clock VCLK to the printer as shown in Figure 11-4. If the information is read out at the clock rate of the station, one bit is padded for each bit of the original information, making it possible to achieve double magnification.

The principle of image movement is explained in Section 12-1. This will be explained using FIG. 12-2.

The sub-scanning direction is realized by scanning the original image and giving VSYNC output timing to the printer as shown in FIG. 12-1.

VSYN when the optical system reaches the position △ with respect to the original.
If you output VIDEO with C, you will get an output that does not move as shown in the figure, and when the optical system reaches the position of △, VS
If VIDEO is output with YNC, an output that moves backward as shown in ■ is obtained, and if VSYNC and VIDEO are output when the optical system reaches the position Δ, an output that moves forward as shown in ■ is obtained.

As for the main scanning direction, as shown in FIG. 12-2, this is done by relatively changing the down count start addresses given to the write address counter 904 and the read address counter 905 via the I10 registers 902 and 903 in FIG. 9.

For example, if the read start address is RADRl for the write start address WADR to the shift memory, the image data XO corresponding to the address WADR has moved to the right with respect to the output main scanning width VIDEOENABLE as shown in the figure (■) =l! It costs 11. Also, if the read start address is PADR2, data X3 corresponding to shift memory address 0 is still VIDEOEN as shown in Figure 12).
It can be seen that it is moving to the left relative to ABLE. 1st
The effective image section signal shown in Figure 2-2 is ST in Figure 9.
Counter 912 and E to counter 913 and F/F 914
This is a trimming section signal composed of gates 915, 916, 917, and 910, 911, and is necessary to use as a white signal for invalid images outside the area between address O and WADR in the shift memory of Fig. 12-2. .

Interface signal timing will be explained with reference to FIGS. 13 and 14.

The BEAM-DETECT signal BD is used to synchronize the rotation of the polygon scanner of the printer when connected to the printer, and corresponds to the leading edge signal of each main scanning line. VI
DEO is an image signal, and 4,678 DEO signals are output with each pixel having a width of about 56 NS per line. When VIDEO is connected to a printer, it is synchronized with the BD, and when transmitted to other units, it is output in synchronization with an internal pseudo-horizontal synchronization signal (hereinafter referred to as HSYNC). VIDEO ENABLE
is a section signal in which 4678 pieces of the image data are output, and is output in synchronization with BD or H5YNC. V
SYNC is a signal indicating the section of the image in the sub-scanning direction.

The PRINT REQUEST signal is a signal that indicates that the printer is ready to feed paper. In response, the reader issues a paper feeding command using the PRIN signal, and then takes into account the magnification, trimming area, and movement amount that correspond to the copy mode set by the operator. VIDE with VSYNC after the time TI

RD C is a signal for controlling backward and forward movement, which is transferred from the CPU section 308 in FIG. 3 to the optical system drive motor driver 311.

In Figure 14, S, DATA, S, CLK, CB
USY and 5BUSY are signal lines for communication between the reader and printer. S.

DATA, S, and CLK are all 8-bit serial data and clock, and all are bidirectional lines. C.B.
USY is output when the reader outputs data and a clock, and CBUSY is output when the printer outputs data and a clock. An example of the content communicated serially is a copy start and copy stop command from the reader to the printer as shown in the timing chart in FIG.

The editing function trimming auto mode according to the present invention will be briefly explained using FIGS. 6 to 8.

In this mode, the sizes DX, MX, and DY-MY are obtained by multiplying the recognized document sizes DX and DY by the magnifications MX and MY, respectively.

As shown in Figure 1, one sheet of paper is sufficient in the sub-scanning direction, and the center is automatically moved in the sub-scanning direction. Conversely, DX-MX≦PX and DYΦMY>PY
In this case, the center is automatically moved to one sheet of paper in the main scanning direction as shown in FIG. 8-2. Also, when DX-MX≦PX and DY・MY≦PY, one sheet for both the main and sub-scanning directions, that is, one sheet in total, is sufficient as shown in Figure 8-3, and the center is automatically set in the sub-scanning direction.

FIG. 5-2 shows an execution flow of the editing function trimming auto-copy according to the present invention. First, a preliminary scan is performed to recognize the position and size of the original (SP501).The above-mentioned coordinate detection logic determines the coordinates of PO and Pi of the original placed on a glass ball as shown in Figure 6-1. obtained,
Data on RAM xl) 7DXO, DXl, DYO

The size in the direction (main scanning direction) DXI-DXQ and the size in the Y direction (sub-scanning direction) DY 1-DY O are stored in the RAM (7) Data Z! J7DX.

Set each in DY (SP502), and then set the length in the main scanning direction and the length in the sub-scanning direction of the sheet selected by the operator in area PX on the RAM.

PY (SP503), and further set the main scanning direction magnification and sub-scanning direction magnification selected by the operator to areas MX and MY on the RAM, respectively (SP5
04).

Next, DX φMX=NX-PX-ax (0<ax<P
X) becomes NX and DY-MY=NY-PY-ay (0
NY is calculated such that <ay<PY) and is set in the data area on the RAM (SP505).

From this calculation, the paper selected by the operator will be NX sheets in the main scanning direction and NY sheets in the sub-scanning direction, for a total of N sheets to compose the document size multiplied by the magnification selected by the operator.
It turns out that you need X/NY pieces. On the other hand, the paper sizes px, py and magnifications MX, M selected by the operator
From Y to TX=PX/MX, TY=PY/MY J: Calculate the size of the retrimming area and set the RAMI area TX
, TY (SP506), the aforementioned NX, N
From Y, in order to read the document size DX by trimming the area of size TX in the main scanning direction by NX images, SX = (DX-TX -NX) / (NX-1)
is calculated, and adjacent trimming areas are overlapped in the main scanning direction by a length corresponding to this SX. Similarly, in the sub-scanning direction, SY= (DY-TY -NY)/(NY-1
) is calculated, and these SX and SY are set in the area on the RAM (SP507).

The following NX, NY, TX, TY, SX, and SY in 1- are illustrated in FIG. 6-2.

Counters for performing trimming in the order indicated by the arrows in FIG. 6-2 are secured in areas i and j on the RAM, and an initial value of 0 is set (S P 508).

In this copy mode, the operator only needs to set the original, magnification, and paper conditions, and the CPU automatically calculates the number of sheets required to compose the desired size output, so the NX in the number display section.
Display NY (Sr509). Next, counters i and j for trimming are each incremented by l (Sr510, 5P511).

Generally shown in FIG. 6-2 [(i.

j) Trimming area = j-th trimming area in the main scanning direction, i-th trimming area in the sub-scanning direction'', that is, the coordinates for determining the NY(i-1)+j-th trimming area are KXiO, KXil, K

KX i □ +TXKY i □=DYo
+ (j-1) ・ (TY-SY), KYi
It is calculated from 1=KY i O+TY. These are calculated and set in the RAMh area (Sr512).

Next, while reading and scanning the image, only the necessary area is trimmed using the above-mentioned means based on the previously calculated trimming area coordinates, subjected to magnification processing such as MX and MY, and outputted on a designated sheet (Sr513).

When image reading is complete, count down the number of sheets by 1, that is, display NX-NY-NY (+ -1)-j (
Sr514), NX regarding changes in the display on the number display section.
The case of jA =2 and NY=3 is shown in FIG. 15 as an example.

This allows the operator to know how many sheets will be output. Next, it is determined whether or not trimming has been performed NY times in the sub-scanning direction (Sr515), and if No, the trimming execution counter j in the sub-scanning direction is incremented by 1 (Sr511), and the process proceeds to the next trimming process. YES
In this case, set the trimming execution counter j in the sub-scanning direction to 0.
After clearing (Sr516) NXX about main scanning direction
Determine whether human trimming has been performed (Sr517).

If No, the trimming execution counter i in the main scanning direction is incremented by 1 (Sr510), and since the sub-scanning direction counter j has been cleared to O, it is also incremented by 1 and the process proceeds to the next trimming process, if YES The trimming process is performed a total of NX-NY times.

Since the copy output of NX-NY sheets has been completed, copying in this mode is ended.

By the above procedure, the original placed on the original table glass 7 as shown in Fig. 6-1 is transferred to TX, TY as shown in Fig. 6-2.
It is possible to automatically obtain a total of NX-NY copies by dividing the trimming area of size sx and sy into NX-MY pieces without overlapping them by sx and sy, and trimming them in order in the direction of the arrow.

On the other hand, like the output copy l - An enlarged copy with MX and sub-scanning lengths DY and MY can be obtained.

In this example, the maximum paper size is A3 and the maximum magnification is 400%, so the maximum output that can be obtained is 1188 mm in length in the main scanning direction.
, it is possible to provide an image processing device that automatically divides and outputs a plurality of copies without any effort when the length in the sub-scanning direction is 168 digits.
