<Description of color reader 1> First, the configuration of the color reader 1 will be explained.

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 1-magnification full color sensor that collects the reflected light image from the original that has been exposed and scanned by a halogen exposure lamp lO. 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 999 documents.
is exposed and scanned in the direction of arrow (A1). 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. In addition,
The signal line 501 has a coaxial cable configuration to ensure faithful signal transmission. A signal 502 is a signal line that supplies drive pulses for the same-magnification full-color sensor 6, and 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 correcting the white level and black level of the image signal, and by irradiating them with the halogen exposure lamp 10, signal levels of predetermined densities can be obtained, respectively. White level correction.

Reference numeral 13 denotes a control unit that controls the entire color reader l of this embodiment, which has a microcomputer, and performs display on the operation panel 2°, human key control, control of the video processing unit 12, etc. via a 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 IO by the exposure lamp driver 21 via the signal line 504.
Color reader section 1 that controls N10FF control, light amount control, digitizer 16 and display section via signal line 505, etc.
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 I+ during original exposure scanning is sent to the sensor output signal amplification circuit 7. It 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.

Video processing unit! The color image signal inputted to 2 is separated into three colors, G (green), B (blue), and R (red), by a sample hold circuit S/H43. 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 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. Dark-time unevenness of the sensor 6, unevenness in the light amount of the halogen exposure lamp IO, variations in sensor sensitivity, etc. are corrected.

Color image data proportional to the amount of human light from the color reading sensor 6 is input to a video interface 201 and connected to the image storage device 3 .

This video interface 20! is equipped with the functions shown in FIGS. 3 to 6. That is, (1) black correction/
A function of outputting the signal 559 from the white correction circuit 46 to the image storage device 3 (FIG. 3), (2) a function of inputting the image information 563 from the image storage device 3 to the selector 119 (FIG. 4) (3) Function of outputting the image information 562 from the combining circuit 115 to the image storage device 3 (FIG. 5) (4) Function of inputting the binarized information 206 from the image storage device 3 to the combining circuit 115 (FIG. 6) 5) Control line 207 between image storage device 3 and color reader 1 (lines such as H5YNC, VSYNC, image enable EN) and communication line 561 between CPU
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 the signal lines 205, 206,
207 is capable of bidirectional transmission.

This configuration enables bidirectional transmission, reduces the number of signal lines, makes the cable thinner, and makes it cheaper.

Similarly, the signal line of the interface connector (4550 in FIG. 27(A)) of the image storage device 3 connected to the color reader 1 is also capable of bidirectional transmission.

Therefore, the number of connection lines between devices constituting the system can be reduced, and furthermore, high-level communication can be performed with each other.

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 = OO)! , black = FFH (The image source that is converted and input to the image reading sensor, for example, a normal reflective original, a transparent original such as a film projector, and even the same transparent original as a negative film, a positive film, or a film Since the input gamma characteristics differ depending on the sensitivity and exposure state,
As shown in b), there are multiple LUTs (look-up tables) for logarithmic conversion, which are used depending on the purpose.Switching is done using the signal lines i!go, l1g1.fg2
This is performed by inputting an instruction from an operation unit or the like as the I10 port of the CPU 22. Here each B,
The data output for G and R corresponds to the density value of the output image, and the data output for B (blue), G (green),
Yellow and magenta respectively for each R (red) signal.

Since this corresponds to the amount of cyan toner, the subsequent color image data will be 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 filters arranged for each pixel in the color reading sensor are as shown in FIG. , has unnecessary transparent areas such as the shaded area, and on the other hand, for example, the color toner transferred to the transfer paper (
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, for each color component image data Yi, , Mi, Ci, there is a masking correction that calculates a linear equation for each color and performs color correction.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 UCR is shown. The characteristics of this configuration are: ■ It has two masking matrices, and can be switched at high speed with one signal line "Ilo." ■ One signal line "Ilo" with and without UCR, 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 M5. A second matrix coefficient M2 is set via a bus connected to the CPU 22. In this example, M1 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 "1" and select B when the S terminal is "0". Therefore, when selecting the matrix M, the switching signal MAR
When EA566="1" is selected, matrix M2 is set to "0".

Further, 63 is a selector, and selection signals C8°C, (
567, 568), outputs a', b, and c are obtained based on the truth table of FIG. 10(b). Selection signal C
o, C, and C2 correspond to color signals to be output, for example, in the order of Y, M, C, Bk (C2°CI, Co

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

EA572 has UCR (undercolor removal), with and without “I”.
The configuration allows for high-speed switching at "lo".

The multipliers 66a, 66b, and 66c each have (ayx, -bMl, -Oct) for eight inputs, and the above-mentioned inputs (Yi-(ak-b), Mi-(ak-b) for the B inputs).

d, e, and r are constant parameters) are signals that rapidly switch the characteristics of each area. It is configured. Therefore, images obtained from image input sources with different color separation characteristics or multiple images with different black tones, etc.
As in this embodiment (this is a configuration that can be applied when combining), these area signals MAREA, UAREA, KA
REA (566°572, 573) is 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.

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 are the achromatic parts of the manuscript and the edges (i.e., black characters).

In order to detect the black line), the luminance signal Y1 and the color difference signals I, Q are changed to Y, 1. It is calculated by the Q calculation 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, the amount of toner at the edge portion of a black character (or black line m>), as shown in FIGS. 12(a) and (b), respectively. It consists of a lookup table with certain 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.This signal is selected by the selector 76 during black toner printing by the signal 577 which becomes "1 degree" during black toner printing, and the signal 5
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 cyan) toners, it is desirable that the Y, M, and C toners not be printed on black characters and black lines.
In response to the color selection signal 577, the selector 76 outputs "l" to the multiplier, and the selector 79 outputs "l" to the LUTB 73.
The signal obtained by smoothing the output from 6 (Fig. 12(d)
(v)) is output, and the adder 78 outputs (d) (
The same signal as in v) is input, and only the signal from the black edge portion is subtracted from the original signal.

In other words, the signal that determines the amount of black toner for the black edge area is strong, and by increasing the amount of black toner and decreasing the amount of Y, M, and C toner for the same area, the black area can be reduced. Blacker (to express).

A signal 581 obtained by binarizing the achromatic color signal 580 by the binarizing circuit 80b is "B" when the color is achromatic, and "0" when the color is chromatic.

That is, as mentioned above, in the selector 79, when printing with black toner (when 577="l"), the S input becomes "l", and the A input, that is, 579 (FIG. 12(d) (ii)
i)) is output and the black edges are emphasized. Y, M, C
During toner printing (when 577="0"), signal 581="
Therefore, if the color is achromatic, the S input is selected to reduce the amount of toner for Y, M, and C, and as shown in Fig. 12 (d

0, therefore 581=1. That is, S of selector 79
The input becomes 1, A is selected, and the state shown in FIG. 12(d) (ii
The signal of i) is output to adder 78 for conventional (known edge enhancement).

The LUTA 73a has a LUT and a LUT that are zero when the edge signal value is less than or equal to ±n, as shown in FIG. 12(a).
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
Select the LUT that is clamped to zero at A'B' in figure (a), or select the LUT that is clamped to zero at A and B when the concentration is below a certain level, that is, when the output of the comparator 81 is "0". In this way, the noise removal effect is changed depending on the concentration 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 58 input to AND gate 584
6 is the LUTC (Fig. 12 (C)) for the edge signal mentioned above.
The signal obtained by applying the characteristics of the edge signal is binarized by the binarization circuit 80a. That is, when the absolute value of the edge signal is above a predetermined value, it becomes "1", and when it is below, it becomes "O". Therefore, 5

2"L" is achromatic color and when the edge signal is large,
In other words, at the edge of the black signal, and also at the Y, M, C
This is 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-B, the output of the averaging circuit 84 is output to the output 589, and when ER=“0”, 0” is output to the output 589. The peripheral color toner (Y, M, C) signals are completely “
0'' to further eliminate color fringing, and these options are selectable.

FIG. 13 shows area signal generation (

This shows a configuration in which the number of sections having a section length of 9 is programmable by the CPU 22 and can be obtained in large numbers. In this configuration, one area signal is generated by one bit of RAM that can be accessed by the CPU, and for example, zero area signals ARE

No area section is generated and no area is set.

FIG. 13(d) shows this circuit configuration, and 85A and 85B are the aforementioned RAMs. This is done by, for example, having the CPU 22 perform a memory write operation for setting a different area to the RAM 885B while reading data line by line from the RAM 35A in order to switch between area sections at high speed.

By setting Cl5)=(1,0,1), 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.

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, a detection output 592 of a color conversion circuit, which will be described later, can be used to create an area restriction mask that limits the area only to a specific color area in the document.

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 comparator 97 in FIG. 14(a) Output 5
97 is "l" when the signal 597 is "14" and "0" when it is "4".
”, therefore, the latch pulse 59 in FIG. 14(d)
8, each block of 4×4 is latched once by the latch 98, and the Q output of the latch 98 becomes the DIN input of the memory 99, that is, the mask creation data. l OOH is an H address counter that generates the 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
Counting up is performed using a clock frequency divided by 4 by 1H.

Similarly, 100V 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 H3YNC of each line is controlled by the frequency divider 101V.
is counted up by a clock whose frequency is divided by 4, and the operations of the 11th address and the {circle around (2)} address are controlled in synchronization with the counting (addition) operation of the ``bi'' in the 4×4 block.

Also, ■lower 2 bits output of address counter, 599
, 600 are NOR'ed by a NOR gate 102 to generate a signal 602 that gates the clock 601 divided by 4, and an AND gate 103 to generate
As shown in FIG. 4(C), a latch signal 598 is generated so that latching is performed only once in a 4×4 block. Further, 603 is a data bus included in the CPU bus 508 (FIG. 2), 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" and the gates 104,
105 and 106 are opened, the address bus and data bus from the CPU 22 are connected to the memory 99, and predetermined data is written at random, and WR (write) and RD read are sequentially performed by the H address counter and ■address counter. If this is done, the control lines for gates 107 and 108 connected to I10 port
7,108 is opened and sequential addresses are provided to memory 99.

For example, the output 593 of the binarized output 92, the output 592 of the color conversion circuit, or the 16th
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 at about 4 pixels, so the interpolation circuit 109 in FIG. 2 smooths out the jagged portion to give it a smooth appearance. Make it.

FIG. 17(a) shows a block diagram of the interpolation circuit. 110 is a selector, and the A input is a Hi clamp, that is,
If it is 8 bits, FFH is input, and GND, ie, 00H, is input 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 for the area mask and 00H for the area mask. This is as shown in (1) in FIG. 17(b). The interpolation circuit 111 uses, for example, a linear interpolation method, a high-order interpolation method,
Any circuit such as an interpolation method may be used, and a well-known circuit configuration may be applied. Since the output of the interpolation circuit is multi-valued, it is binarized by the binarization circuit 112. As a result, the smoothness of the boundary is ensured as shown in (11) in FIG. 17(b) (with respect to the original boundary A and B. The switching signal 608 connected to the I10 port of the CPU 22 determines whether to output the signal as is (select A) or select and output a mask signal with smooth boundaries after interpolation as described above. Therefore, for example, if the signal 608 selects the interpolation output, and the selector 89 in FIG. 2 switches the ECH to select the area limit mask output, the AND gate 90 selects the output by the mask as shown in FIG. 18(a). It is possible to cut out a non-rectangular figure.Furthermore, if the output of the mask memory of the bitmap memory 91 is taken out from the signal line 607 in FIG. 2, selected by the selector 114, and synthesized by the synthesis circuit 115 described later , as shown in FIG. 18(b).

Initialize a pointer (not shown). 611 is input image data, 612 is output image data, and
Signal 6 is a signal that initializes the RD (read) pointer of the FIFO. Therefore, as shown in the timing chart of FIG. 20(b), the data 1 to 10 sequentially written to the FIFO are as shown in the figure.
1 → 2 → 3 → 1 → 2 → 3" is read out repeatedly. In other words, repeats formed identically in each line
By giving the t signal 616 to the FIFO, the same figure (c)
The same image can be repeated as shown below.

Therefore, write data "1" as shown in FIG. 21(A) in the memory for forming the mask area of the bitmap mentioned above
A dotted line (cut line) is formed by combining in the synthesis circuit 115 in FIG. 1 at the time of reading.

The image is as described above (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 data of l” as shown, the four lines become (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 1!5 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. In addition, 130 is a synchronization signal HS Y N
Area code generator and register that automatically generates area codes according to C and CLK! 3! is a register to which a signal from the CPU bus 508 is input. 135,
Reference numeral 136 denotes a RAM in which area codes and processing or image data corresponding to the area codes are stored as a table. As shown in FIG. 25(F), the contents of the table in the RAM 135 and 136 include a code input manually via the selector 132 as an input address, and a code C0, which indicates the formed color when the printer is forming images sequentially. C, and has a 3-bit function code and 8-bit data as its output. Note that this 3-bit function code is given to the decoder 146 via the selector 137. 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 decoder outputs SO, 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. 14
6 is the most significant bit MSB 621 of the 6-bit data input via the selector 132 (this MSB is the second
As shown in FIG. 5(E), the area code generator 130 outputs '1' at the end of each area of the image), the character signal and selector indicated by signals 613 and 614 in the second figure. This is a decoder that decodes three function codes inputted via the 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).
For 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 document is scanned, areas are distinguished by the area code, and different image processing and editing can be performed 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) shows an example of a schematic internal configuration diagram of the area code generation circuit shown in FIG. 25(A) 130. The generating circuit 130 is a circuit that generates the above-mentioned area code in real time simultaneously with the operation of the document, and programmably generates the area code by setting the area coordinates and area code obtained by the area specifying means such as the digitizer. It is designed to occur. 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

155 is an interrupt generator which generates an interrupt signal INT to the CPU when it counts HSYNC which is inputted from the CPU in advance by the CPU data bus 625 and chip select 624, and also outputs a flip-flop to J-. The RAM read out by the address counter 149 is also switched by the toggle operation of the switch 158. 151, 152° 156 is a selector which selects A according to the output of the flip-flop 15B.

It is divided into it 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).

It is said that The reversely set area has the area code “20”
This is an example where the RAM with the above settings is
FIG. 5(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, the 25th
When scanning the section shown in Figure (E) A-H, the MSB “!” and the lower 6 bits are “

As shown in C), the lower 6b is latched by the latch 157 using the MSI3627 as a latch signal, and the area code "0" is output. Also, when the point a(0,P) is reached, the MSB "1" and the lower 6 bits "20" are read out as the output of the RAM, and the area code "20°" is latched in the same way as above.Furthermore, the address As time progresses, the area code "2o" is output until the next MSB becomes "B". That is, the address r is read and the area code "20" is used until the data is newly latched as described above.
” 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 one step in the X direction and HS Y N C is sent to the interrupt generator 155.
It is counted by At this time, the address counter 1.49 is reset as described above, and the read address also starts from O again. Furthermore, since the area is rectangular, the same data, that is, RAM 153.
Either one of the RAMs continues to be read out, and the
If the count number, in this example (q-o), is set, the interrupt generator 155 will generate the interrupt signal INT when scanning from section A-B to section C-D is completed, and at the same time, the Figure 25 (C) Flip-flop 15 on J-
The RAM read out by the selector 156 is switched by the toggle operation of step 8. As a result, the next area information programmed in advance is output from the RAM selected by the selector 156. Also, interrupt INT
When the CPU generates the interrupt generator 1 from the area coordinates and area code obtained by the above-mentioned means,
55, a new signal corresponding to another specified area is set again in the inactive RAM, that is, the RAM not selected by the selector 156. Such a set is transmitted from the CPU to the data bus 625 and the chip select signal C2,
This is done under the control of C3. The configuration described above, that is, the two RAMs are switched sequentially, and the idle RAM is switched to CP.
By programming with U, the area code 626 can be generated for the entire screen of the document with a small memory capacity.

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

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, by setting the color select signal CON CI + C2 to 2 bits C (..., C1) from the LSB, it is possible to select which of the four colors the image signal is sent in frame sequence (), and thereby select the area code for each color. The address for accessing is changing.

In this embodiment, as will be described later, when forming an image with the printer 2, each color is M (magenta), C (cyan), Y (yellow).
, 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 C6 and CI shown in FIG. 10(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 bits from the MSB, that is, the function code is the second bit.
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
i t62] to create a control signal 623 for each editing process. 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, the RAM data is selected from the selector 139 by Sl, further passes through the selector 145 determined by 33 and S4, is calculated with the image signal by the multiplier 144, and is output. At this time, multiplier 1
The degree of the image is determined from the RAM data manually inputted in 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 appropriate coefficient, for example "l", 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 14.3 selects the data in the RAM 135 or 136, and when it is Low, the selector 14.3 selects the image signal.
The decoder 146 performs insertion by outputting O to S4. In addition to the above character signal, 83. S
4 also changes, and the coefficient of the multiplier 144 becomes high when the character signal 622
At the time of g and h, register 140 is selected. This is also connected to the CI'U bus as described above, and appropriate coefficients are set in advance. Usually register 140
Set 1 to . In particular, by changing the coefficient set in the register 140, the 6th degree of the inserted character can be changed freely.

■ Inserting characters within the area (2) Figure 25 (■ Masking the specified area with a specified color as shown in (), and inserting characters in the same area with another specified color as described above. While scanning the specified area, the selector 143 selects the data of RA and M as described above.At this time, as described above, the data obtained from the bitmap memory shown in FIG. The selector 139 is switched based on the character signal given.

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).

In the figure, 1 to 6 shown in the leftmost column are the above-mentioned ■ 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.

10 is a diagram showing the configuration of 1O and the configuration of FIFO memory in memories A-M. FIG.

The comparator 4232 is set with a start address in the main scanning direction of the area designated by the digitizer 16, and the comparator 4233 is set with a stop address.

Further, the sub-scanning direction of the area specified by the digitizer 16 is controlled by the selector 4213 to select the CPU bus 9610 side and make it valid, and "0" data is written in the valid area of the area specified in the RAM 4212. Invalid area is “
l” data is written.

For scaling processing in the main scanning direction, a scaling factor is set in the rate multiplier 4234 shown in FIG. 29 via the CPU bus 961O. Further, scaling processing in the sub-scanning direction is possible using data written to the RAM 4212.

FIG. 30 is a timing chart when trimming processing is performed. As mentioned above, when storing only the area specified by the digitizer 16 in the memory (trimming processing), the trimming position in the main scanning direction is set in the comparators 4232 and 4233 shown in FIG. For the position, set the selector 4213 to the CPU bus 9610 side, and write to the RA, M 4212 by the CPU ((Example) Set the trimming area to the main scan 1000 to 3
047, sub-scanning 1000-5095 degrees). That is, in the RAM 4212, "l" or "0" is written by the CPU into an area corresponding to each address output from the counter 4214 input via the selector. Here, as described later, “Bi is memory 4050R, G,
Reading of B is prohibited, and "0" is data that causes reading to be performed.

The trimming section signal 9100 in the main scanning direction is H5YN
Counter 4230 operates in synchronization with CIN9452 and CLKIN9456, and this counter output 9103 is 1o.
When it becomes oo, the output of the comparator 4232 becomes 1, and the output Q of the flip-flop 4235 becomes 1.

Subsequently, when the counter output 9103 becomes 3047, the output of the comparator 4233 becomes 1, and the output of the flip-flop 4235 changes from 1 to 0. In addition, in the timing chart of Fig. 30, since the same magnification processing is performed,
The output of rate multiplier 4234 is one. FIFO memory 405 according to trimming interval signal 9100
Color image information 1 input to 0AR, AG, AB

Also, from comparator 4231, HYN IN94
52, a signal 9107 delayed by one pixel is output.

In this way, the FIFO memory 4050AR,AG.

By giving a phase difference to the r input of AB, the difference in the cycles of CLKIN9456 and CLK9453, which are input to the FFO memories 4050AR, AG, and AB, is absorbed.

Next, for trimming in the sub-scanning direction, first select the counter 4214 side that controlled the selector 4213 in FIG. RAM421
Output from 2. The interval signal 9104 is synchronized with the signal 9107 by a flip-flop 4211, and is input to the read enable of the FIFO memories 4050AR, AG, and AB. That is, FIFO memory 4050AR,AG.

The image information stored in AB is the trimming signal 9101
Only the section where is "0" is output (n-m).

Further, as shown in FIG. 32, the signal 9101 is input to the counter controller 9141 and becomes a counter enable signal, and also serves as a write enable signal for the memories 4060A-R, G, and B, and as described above, the FIFO memories 4050A and R , G, and B are immediately stored in memory 4060A-R according to the address output from counter 4080A-0.

Written to G and B.

In the above description, only the trimming process has been described, but the scaling process can be performed simultaneously with the trimming. For scaling in the main scanning direction, a scaling factor is set in the rate multiplier 4234 via the CPU bus 96!0. Also, sub-scanning is RA
Scaling processing is possible depending on the data written to M4212.

FIG. 31 shows a timing chart when trimming processing and scaling processing (50%) are performed.

FIG. 31 shows that the image data from selectors 4254R, G, and B are scaled and reduced by 50%, and then stored in FIFO memory 405.
It is a figure which shows the example of a timing chart when transferring to 0AR, AG, and AB.

A setting value of 50% reduction is set in the rate multiplier 4234 in FIG. 29 via the CPU bus 9610.

At this time, the output of the rate multiplier 9106 is the 31st
As shown in the figure, it has a waveform in which "0" and "B" are repeated for each pixel in the main scanning direction.A section signal 9105 is created by this signal 91.06 and comparators 4232 and 4233.
The AND signal 9100 with FIO memory 4050AR,
Reduction is performed by controlling write enable to AG and AB.

In addition, the sub-scanning is used to write data to the RAM 4212 (FIFO memory 4050AR, AG) as shown in FIG.
.

By setting the read enable signal to AB to "l" (reading prohibited) within the image data valid area, 50%
Only the reduced image data is stored in the image memory 4060AR,
Sent to AG and AB. In the case of FIG. 31, the read enable signal 9101 is reduced by 50% by repeating "1" and "0" data alternately.

In other words, trimming and scaling processing in the main scanning direction are performed using F.
The FIFO memories 4050AR, AG control the write enable of the IFO memories 4050AR, AG, AB, and perform trimming and scaling processing in the sub-scanning direction.

Controls AB read enable.

Next, FIFO memory 4050AR, 4050AG,
4050AB to memory 4060AR, 4060AG,
Transfer of image data to 4060AB is performed by counter control 9141A and counter 4 shown in FIG. 27(C).
080Δ-0 to 3 and control line 9101.

Note that 9101 is the output of the comparator 4231 shown in FIG. 29, and is used as read enable RE of FIFOs 4050R, G, and B, and write enable of memory 4060A-R-3 shown in FIG. 32.

Counter control 9141A shown in FIG. 27(C)
is a circuit that controls counters 4080A-0 to 4080A-3 that generate addresses for memories 4060A-R, G, and B, and has the following three main functions according to commands from the CPU.

! , CPU read/write mode → data at any address can be referenced by the CPU.

2. Read mode → Read the stored image data according to the control signal of the system controller and transfer it to the color reader l to obtain a printout.

3. Light mode→Stores the image from the color reader 1 according to the control signal of the system controller.

In either case, the count start address of the counters 4080A-0 to 4080A-3 can be arbitrarily set by the CPU. This allows reading and writing from any address. Normally the start address is address 0.

Control line 9101 is FIFO memory, 4050AR.

This is a read enable signal for AG and AB, and is also input to the counter control 9141A to control the counter. Furthermore, it is also a write enable signal for the memories 4060AR, AG, and AB.

In the write mode, the counter control 9141A converts the input control signal 9101 to the counter 4080A-
It is used as a counter enable signal of 0 to 3, and the counter control may select a counter according to a CPU command or select all counters. 9140A is a control line 9 which is a counter selection signal.
When 101 is “0”, FIO memory 4050R, G, B
The image data read from the memory 4060R, G,
It is input to B.

At this time, for example, if counter 4080A-0 is selected, the enable of counter 4080A-0 is "0".
The count increases in synchronization with CLK9453.
A signal 9120-0 is output from the counter 4080-0, passes through the selector 4070, and is stored in the memory 4060ARA.
It is input to ADR9110 of G and AB.

Also, at this time, the write enable WE9101 of the memory 4060AR, AG, AB is also "0", so
Image data 9090R, G, B input to memories 4060R, G, B are stored.

Note that the memory capacity in this embodiment is 1M bytes for each color, so by reducing the image data in the reading area in FIG. It is converted into and memorized.

Further, in the above embodiment, the CPU 4360 calculates the effective area from the information of the area specified by the digitizer 16 of the A3 original, and calculates the effective area from the information of the area specified by the digitizer 16 of the A3 document,
3. Rate multiplier 4234 and RAM4
The data corresponding to 212 is set.

In this embodiment, since the data capacity of the read image was larger than the image memory capacity, a reduction process was performed to convert the data to a storable capacity and then store it in the image memory. However, if the data capacity of the read image is smaller than the image memory capacity, the comparators 4232 and 42 control the writing of the area specified by the digitizer 16 into the memory.
33 is set with trimming information data, and a rate multiplier 4234 is set with equal magnification. Also, R.A.
The write data to M4212 is set to "0" for all image valid areas and "l" for other areas, and set to the same size.

In addition, in order to store the read image in memory while maintaining its aspect ratio (vertical/width ratio), the CPU 4360 first
calculates the number of effective pixels "X" from the area information sent from the digitizer 16. Next, 2 is determined from the maximum capacity "y" of the image storage memory using the following equation.

X100=z As a result, (1) When z≧100, rate multiplier 42
Setting No. 34 stores the entire effective image area in the 100% RAM 4212 as "0" at the same size.

(2) When z<100, rate multiplier 423
4 and the RAM 4212 are reduced by 2% and stored in the maximum capacity of the memory while maintaining the aspect ratio.

Even in this case, the data to be written into the RAM 4212 may be "1" and "0" data written in accordance with the reduction ratio "z" at appropriate times.

By controlling in this way, it is possible to perform arbitrary scaling processing with easy control while maintaining the aspect ratio of the input image by controlling only the image storage device 3, and it is possible to effectively recognize the read image. Become. At the same time, it is possible to maximize the utilization efficiency of memory capacity.

Additionally, the settings described above can be set independently for the image storage memo 1 (memories A, B, C, D) and the display (memory M) shown in Figure 27 (E). When storing the same image at different magnifications, the same image can be stored simultaneously in different memories, e.g., memories A, B,
It can be stored in C, D, memory M, etc.

Among the image data read from the color reader, the image data written to the bitmap memory E is selected by the selector 4250 as described in the previous section. FIFO 4050E shown in FIG. 27 (D-1) in memory E through filter 9500
-Written to R. In such a case, writing is controlled by the write enable 9100 in the same way as described in FIG. 29. At this time, in this embodiment, only the R signal is used as an image signal (any other signal, such as a luminance signal, may be used. For example, the G signal, R, G, and B are weighted and averaged at a predetermined ratio. It may be the signal taken.FIFO
The image data written to 4050E-R is read out by the control signal 9101 as explained in the previous section, and the image data written to 4055-
The data is binarized by the binarization circuit shown in R and sequentially written into the memory. At this time, black becomes "l" and white becomes "0".

The CPU writes a predetermined value to the register 4053 via the bus as the binarization threshold. For example, Fig. 27 (D-2

It is stored in 0AR, 4050AG, and 4050AB at the same size.

<Reading process from image storage device> Next, the memory 4060A of the image storage device 3 described above
The process of reading image data from R, 4060AG, and 4060AB will be described.

Inputting instructions and the like when outputting an image from this memory to form an image on the color printer 2 is performed mainly by the digitizer 16 and the operation section 20 shown in FIG. 23 described above.

For example, when an area where an image is to be formed is specified using a digitizer as shown in FIG. send.

Such position coordinates are output as 8-dot data, for example.

The CPU 4360 generates a region signal generator based on the coordinate information sent to the region signal generator 4210-2 (similar to the one shown in FIG. 13(d)) in the system controller 4210 shown in FIG. 27(F). is programmed to obtain the desired image output. Specifically, R shown in FIG. 13(d)
Data corresponding to the coordinate information is set in AM85A and 85B. FIG. 27(F) shows each signal output from the area signal generator, and each becomes a control signal for each area.

When the above-described program is finished, the image storage device 3 waits for a command from the color reader 1, and by pressing the copy start button, image formation is started.

When the start button is pressed, the color reader l sends the command to the CPU 4360 of the image storage device 3 through the signal line 4550, and the CPU 436 that received the command
0 causes the selector 4250 to switch instantly. 28th
In Figures (B) and (C), the settings for sending images from the image storage device 3 to the color reader 1 are 5ELECT-C, 5E.
LECT-E and 5ELECT-F are set to "O" to open the gates and all other tri-slurt buffers are set to high impedance. Further, the CPU 4360 sets the counter controller of the memory in which the desired image is stored to read mode.

With the above settings, start timing signals 1-TOP and BD are received from color reader 1. On the other hand, the color reader 1 obtains an image signal and a CLK image enable signal from the image storage device 3 in synchronization with the timing signal.

First, an embodiment in which an image is formed according to the size of recording paper, and then an embodiment in which an image is formed in an area designated by a digitizer will be described.

<Image formation processing corresponding to the size of recording paper> In this embodiment, the color printer 2 has two cassette trays 735 and 736, as shown in FIG. 1, and two types of recording paper are set therein. . Here, A4 size in the upper row,
A3 size recording paper is set in the lower row. This selection of recording paper is input through the liquid crystal touch panel of the scanning section 20.

Note that the following description will be made regarding the case where a plurality of images are formed on A4 size recording paper.

First, prior to image formation, read image data is input to the image storage device 3 from the above-mentioned color reader 1, film scanner 34, or Sv recording/reproducing machine to image memories 4060AR and 4060AG, which will be described later.

For example, as shown in FIG. 33, a total of 16 image data from "Image O" to "Image 15J" are stored in 4060AB.

Next, press the start key on the operation panel.

As a result, the CPU 22 shown in the second figure detects this key manual force and automatically sets the image forming position on the A4 size recording paper. When forming the 16 images shown in FIG. 33, the image forming positions are set as shown in FIG. 34, for example.

The details of the above image forming process in this embodiment will be explained below with reference to the block diagram in FIG. 27 and the timing chart shown in FIG. 35.

IT sent from the color printer 2 shown in FIG. 2 to the color reader l via the printer interface 56
The OP signal 511 is input to the video interface 201 in the video processing unit 12 and is sent from there to the image storage device 3. The image storage device 3 starts image forming processing in response to this ITOP signal 551. Each image sent to the image storage device 3 is read out from the memory ABCD etc. under the control of the system controller 4210 shown in FIGS. 27(A) and 27(B) in the image storage device 3.

Control signal 9102- output from the area signal generator (FIG. 27(F)) in the system controller 421O
0 to 3 are input to the counter control 9141 to serve as counter enable signals.

The counter control 9141 enables the counter and controls the select signal 9140 of the selector 4070 based on the input control signal. At the same time, the counter control 9141 outputs a read enable signal 9103, and this signal
This becomes a write enable signal for 4140-0 to 4140-3.

With this access, each memory 4060AR, 4060A

B is input to the masking/black extraction/UCR circuit 4120. The masking/black extraction/UCR circuit 412OA performs color correction of the color image signal of the image storage device 3, and also performs UCR/black extraction during black recording.

The image signal 9210 from these continuously connected masking/black extraction/UCR circuits 412OA is processed by the selector 4130 shown in FIG. 27(B) based on the select signal 9230 output from the area signal generator. It is input to each FIFO memory 4140-0 to 4140-3. As a result, the images that were arranged sequentially as shown in FIG. 33 can be processed in parallel by the action of the FIFOs 4140-0 to 4140-3.

FIG. 35 is a timing chart showing the flow of the images described above.

Enlargement interpolation circuit enable signals 9340 in FIG. All of these are output from a region signal generator, and up to four regions can be enlarged independently.

For example, when the enlargement interpolation circuit 4150-0 is enabled by the enable signal 9320-0, the enlargement interpolation circuit 4150-0
150-0 outputs a read enable signal 9280-0 to FIFO 4140-0, receives image data from FIFO, and performs enlargement processing. Note that this embodiment uses a linear interpolation method. Similarly, when the other expansion interpolation circuits are enabled, they issue a read enable signal to the FIFO and read the data from the FIFO. FIG. 35 shows a timing chart.

At this point, as described above, the image data read out sequentially from the memory is processed in parallel, and finally the image layout is completed by the selector 4190, and each image data that has been processed in parallel is serialized again. image data signal. The image signal 9330 converted into serial image data by the selector 4190 is
Edge filter circuit 4180 performs edge enhancement and smoothing processing. And L
It passes through the UT 4200 and is input to the selector 4230 via a signal line 9380.

The data (2E) in the bitmap memory described above and the image data from the memory are input to the selector 4230.

Details of such two switching will be described later using FIG. 41.

The image signal 9380 output from the selector 4230 is input to the selector 4250 as ■ and is sent to the color reader 1 together with the video enable signal generated from the area signal generator shown in FIG. 27(F) and the clock.

Hereinafter, when the formation of all image data for "Image 0" to "Image 3" is completed, next "Image 4" to "Image 7", "Image 8" to [Image 11], [Image 124 to "Image Images are sequentially formed in the order of 15J, and 16 images from "Image 0" to "Image 15J" shown in FIG. 34 are formed.

As described above, in this embodiment, 16 images are stored, laid out and printed out as shown in FIG. 34, but the number of images can be set arbitrarily.

Furthermore, in the case of images from the SvB reproducing device 31, it is possible to continuously print out images on an S floppy disk, and it also has a function as an index print.

Similarly, the film scanner 34 uses an autochanger to automatically store images one after another and print on 24 or 36 pages, thereby making it possible to perform index printing of film images.

<Image Formation by Layout at Any Position> The above explanation describes control for developing and forming an image so that it can be automatically formed as shown in FIG. 34, but this embodiment is limited to the above example. It is also possible to form an image by developing an arbitrary image at an arbitrary position.

Hereinafter, as an example of this case, [Image 0] shown in FIG.
A case will be described in which "Image 3" is developed as shown in the figure and an image is formed.

First, the color reader l, film scanner 34 or S

Then, operate the point ben 421 to detect the coordinate detection plate 42.
Specify and input the desired deployment position from 0. For example, a development area is designated and input as shown in FIG. 37.

The image forming process in this case will be described below with reference to block diagrams shown in FIGS. 27A to 27F and timing charts shown in FIGS. 38 and 39.

FIG. 38 is a timing chart when forming an image on the lines "1" and "1" shown in FIG. 37, and FIG. 39 is a timing chart when forming an image on the "12" line shown in FIG. 37.

The ITOP signal 551 is output from the printer 2 in the same manner as described above, and the system controller 421O starts operating in synchronization with this signal.

Note that in the image layout shown in FIG. 37(A), "Image 3" is
Alternatively, the image from the Sv recording/reproducing device 31 is rotated by 90 degrees.

This image rotation process is performed in the following steps.

First, 4060AR is accessed by DMAC (direct memory access controller) 4380 in FIG.

Work memory 439 from 4060AG 4060AB
Transfer the image to 0. Next, after the CPU 4360 performs known image rotation processing in the work memory 4390, the DMAC 4380 rotates the image in the work memory 4390.
Images will be transferred from there to 4060AR, 4060AG, and 4060AB, and image rotation processing will be performed.

The position information of each image laid out and inputted by the digitizer 16 is stored in the video processing unit 1 in FIG.

The above position information is transmitted to the CPU 4 via a signal line 9460.
360. As described above, the CPU 4360 programs the area signal generator based on the position information.

The system controller 421O, which has received the development position information for each image, sends operation permission signals 9320-0 to 3 and counter enable signals 91020 to 3 for the enlargement/interpolation circuits 4150-0 to 4150-3 corresponding to each image, and controls each selector. A signal is generated to obtain the desired image.

In the layout at any position in this example,
For example, counter 0 (4080-0) is set to image 0, counter l (4080-1) is set to image l, counter 2 (
4080-2) is image 2, counter 3 (4080-
3) operates corresponding to image 3, respectively.

Control during image formation on the "11" line shown in FIG. 37 will be explained with reference to FIG. 38.

Similarly, "Image l" is read by counter 1 (40

The data of “Image 0” and “Image l” are stored in LUT411
It is sent to the masking/black extraction/UCR circuit 412OA via 0AR, 4110AG, and 4110AB, where it becomes a frame-sequential color signal 921O. This frame sequential color signal 921

The FO read signal 9280-0°9280-1 is enabled and read control is started.

The FTFO memory 4140-0.4140-1 starts transferring image data to the enlargement/interpolation circuit 4+50-0.4150-1 in response to this signal 9280-0.9280-1. And this enlargement/interpolation circuit 4150-0°4
150-1 first performs layout and interpolation according to the area designated by the digitizer 16. This timing is shown at 9300-09300-1 in FIG.

“Image 0” and “Image IJ data” subjected to layout and interpolation calculations are selected by a selector 4190, then passed through an edge filter circuit 4180, and then stored in a LUT 4200.
is input. The subsequent processing up to the connector 4550 is the same as described above, so the explanation will be omitted.

Next, with reference to FIG. 39, the timing of "12 lines" shown in FIG. 37 will be explained.

Image memory 4060AR, 4060AG, 4060
The processing from AB to the enlarging/interpolating circuits 4150-1 and 4150-2 is substantially the same as described above.

However, since "Image l" and "Image 2" are output on line 12, counter 1 (4080-
1) and counter 2 (4080-2), FIFO414
0-1, 4140-2, and enlargement/interpolation circuits 4150-1 and 4150-2 operate. These controls are performed according to control signals from system controller 4210.

As shown in FIG. 37, in the "12" line, "Image l"
and [Image 2j overlap. In this overlapping area, the system controller 421 determines whether to form either image or both images.
It can be selected by a control signal 9340 from 0.

The specific control is the same as in the above case.

A signal from connector 4550 is connected to color reader 1 via a cable. Therefore, the video interface 201 of the color reader 1 receives the image signal 205R from the image storage device 3 through the signal line path shown in FIG.
is selectively output to the printer interface 56.

Details of the process of transferring image information from the image storage device 3 to the color printer 2 during image formation in this embodiment described above will be described below with reference to the timing chart of FIG. 40.

As described above, by pressing the start button on the operation unit 20, the printer 2 starts operating and starts conveying the recording paper. When the recording paper reaches the tip of the image forming section, the IT
An OP signal 551 is output. This rTOP signal 551 is sent to the image storage device 3 via the color reader l.

The image storage device 3 stores each image memory 4060AR under set conditions.

The image data stored in the 4060AG and 4060AB is read out and subjected to the above-described processing such as layout, enlargement, and interpolation.

Memory expansion continuous shooting> The image data sent from the host computer 33 is transferred to the GP
Input via IB4580 and work memory 4390
The image data is once developed, written in image memories A, B, C, and D, and read out in the same manner by the means described above to obtain print output. For example, if the image transferred to the image storage memory as shown in FIG. 43 is the memory area read out by counter 0 (408 (1-0)) shown in FIG. Diagram (A
) is printed in the area of image 0.

Further, by sending layout coordinate information, enlargement magnification, and print commands from the host computer, image formation in an arbitrary layout can be performed under the control of the host computer, similar to what was described above.

Furthermore, since the enlargement magnification can be set arbitrarily, an enlarged output image can be obtained beyond the limitations of printing paper.

FIG. 37(G) shows an example in which, for example, an image stored in memory is divided into four print sheets and enlarged and printed (hereinafter referred to as enlarged continuous shooting). Details will be explained below.

Figure 37 (F) is the counter 0 shown in Figure 27/(C).
4080A-0 is a diagram schematically representing an image stored in a memory area read out by the 4080A-0.

As shown in the figure, the memory storage area can be divided arbitrarily depending on the magnification and paper size. When receiving an enlarged continuous shooting command from the host computer, the CPU calculates the memory division size from the paper size and enlargement magnification, and sets it in the system controller and read counter 0.

In the figure, the division size is I] force direction8. These, whose V direction is b, are used to calculate the starting address to be read by the counter.

Further, for simplicity, in the figure, each of the four divided areas corresponds to four printouts.

The image forming process is started by the ITOP signal 55 shown in FIG. When the readout is completed, the readout counter calculates the start address of the next line, repeats the readout again, and reads out up to the b line, and the printing of the first sheet is completed. Next, the head address 2 of the second sheet is calculated until the ITOP signal 551 for the second sheet arrives, and printing is performed continuously up to the fourth sheet while calculating the head address of the second sheet. Finally, by joining the print images together, an enlarged image can be obtained.

<Non-rectangular image synthesis using memory E> Next, non-rectangular image synthesis processing using bitmap memory E will be described.

For example, as shown in FIG. 37(B), a case will be described in which the output area of image 0 is made into a heart shape and is synthesized and output on the document.

As described above, first, a heart-shaped binary image is developed in the bitmap memory E, taking into account the size of the area of the image 0 that is desired to be output. Next, as in the previous section, the development area of each image is designated and input using the digitizer 16 from the color reader l. At this time, the non-rectangular area selection button is selected from the operation unit only for image 0. The position information and processing information of each of these designated images are sent to the image storage device 3 via the first video processing unit 12. As already mentioned, the sent information is read by the CPU 4.360 through the signal line 9460, and the image output timing is programmed based on this information.

Upon receiving the I-TOP signal from the color reader 1, the image storage device 3 starts reading out the image from the memory, and the 27th
Image synthesis is actually performed when passing through the selector 4230 in the figure.

FIG. 41 is a schematic internal configuration diagram of the selector 4230 of FIG. 27(B). 3010 allows the CPU to programmably select 8-bit 1fj once data or the Bl signal from the bitmap memory by controlling the data set in this register using register l.

3020.3030 are gates for such selection. For example, if 8-bit density data is selected, the OR gate 30
At 40, the image signal and the bitmap are combined.

When the 10,000 Bl signal is selected, the selector 3050 becomes a select signal, and image data having the density of the data set in the register indicated by the BI multiplied signal 3050 and image data 9380 from the memory can be selectively output.

When performing non-rectangular image composition, register 2 is normally set to “0”.
” is set.Image data 938 to be read out sequentially
0 is the non-rectangular area signal B output from the bitmap
The non-rectangular image is cut out by the selector 3050 which uses the l select signal, thereby making it possible to synthesize a non-rectangular image.

The Bl signal is sent alone to the color reader 1, and the color reader 1 can also perform processing using the Bl signal.

That is, if the above-mentioned Bl signal is used as the signal 206 input to the video interface circuit 201 of FIG. 2, and the video interface circuit 201 is used in the state shown in FIG. 6, the above-mentioned image synthesis is performed on the reader side. I can do it.

Furthermore, in this embodiment, the image storage device 3 reads the color image read by the reader l in real time.
It is also possible to combine images.

That is, as described above, an image is read from the image storage device 3 in synchronization with the ITOP signal 551 of the color printer 2, but at the same time, the color reader 1 also transfers the reflective original 999 to the full color sensor 6 in synchronization with the ITOP signal 551. and start reading. The processing of the color reader I is the same as described above, so the explanation will be omitted.

The composition of the image information from the image storage device 3 and the image information from the color reader 1 described above will be explained below with reference to the timing chart of FIG. 37(C).

Figure 37(C) shows images 0 to 4 in Figure 37(A).
The other parts are timing charts in which the reflection original 999 in 11 and the signal from the image storage device 3 are combined when the reflection original read by the reader l is combined.

[The image information of the color reader l read out in synchronization with the TOP signal 551 is the output signal 5 of the black correction/white correction circuit.
59RGB, and H5YNC at l in Figure 20.
is output in sync with. Furthermore, only the area designated by the digitizer 16 is outputted from the image information 205RGB from the image storage device 3. These two types of image information are input to the video interface 101, and the digitizer 1
The image of the color original is output from the combining circuit 115 except for the area designated by 6, and the information from the image storage device 3 is output for the area designated by the digitizer 16.

In the above embodiment, as a means for setting a non-rectangular area, a mask button having the shape of the desired area is prepared in advance,
By reading it into the reader, it was expanded into bitmap memory.

Furthermore, in this embodiment, the bitmap memory is connected to the CPU bus as shown in FIG. 27 (D-1), so that the CPU can develop mask buttons in the bitmap memory. For example, in the case of a standard mask button that is frequently used, such as a star, diamond, or hexagon, the data or the program that generates the data should be stored in the CPU's program ROM or font ROM 4070, and when used. can start a program and automatically generate a mask bang.

With the above configuration, there is no need to create and read a mask button, and it is possible to easily create a mask button in the bitmap memory, making it easier to perform image composition as shown in FIG. 37(B). I can do it.

Further, in this embodiment, the CPU 4360 stores the font ROM 4070 shown in FIG. 27 (D-1) from the code data transmitted from the computer 33, for example.
It is also possible to expand the character font onto the bitmap memory shown in E by referring to .

In this way, character fonts can be freely written into the bitmap memory, and furthermore, by activating the AND gate 3020 in FIG.
0 is inactive and the image data 9380 and the image on the bitmap memory are synthesized by the or game 1-3040, thereby making it easy to synthesize characters with various stored image data.

Furthermore, by activating, for example, a bang generation program by the CPU 4360, ruled lines can also be written in the bitmap, and such ruled lines and image data can be easily combined as shown in FIG. 37(D). In addition, various fixed buttons can be provided as CPU programs.

Furthermore, the character data from the font ROM 4.070 written in advance in the bitmap memory and the image data are combined, and a message is printed on the bottom of each image shown in FIG. 34, as shown in FIG. 37(E). Now you can get the image you want. As previously mentioned, these characters can be expanded by sending character codes from the host computer, or can be read and set from the reader.

Description of Monitor TV Interface> As shown in FIG. 1, the system of this embodiment is capable of outputting the contents of the image memory in the image storage device to the monitor TV 32. It is also possible to output video images from the SVQ player 31.

This will be explained in detail below. Image memory 4060AR.

The video image data stored in 4060AG and 4060AH is read out by DMAC 4380 and sent to display memories 4060M-R and 4060M-G.

On the other hand, as described above, the system controller 421
By controlling the control signals output from 0 to each memory, a desired image can be stored in the image memory and also in the display memory M at the same time.

By connecting the C signal 4590S to the monitor 4, the contents stored in the image storage device 3 can be displayed.

In addition, in this embodiment, from the host computer 33 shown in FIG. 1 to the 4580 shown in FIG.
By sending a control command to the image storage device 3 via the B controller 431O, the displayed image can be trimmed.

The CPU 4360 controls the display memories 4410R, 44, and 10G based on the area information inputted by the host computer 33 under the same control as described above.

From 4410B to image memory 4060AR, 4060AG

Trimming is possible by transferring only the effective area to 4060AB.

In addition, in response to the area instruction information from the host computer 33, the CPU 4360 shown in FIG.
By setting the data in the same manner as in the case described above in step 2, and inputting the image data from the color reader 1 or the SV recorder/player 31 again, the trimmed image data can be converted to 4.

The reading control of stored information from the 060AB to the color printer 2 and the recording control in the color printer 2 are the same as in the embodiment described above, so the explanation will be omitted.

Description of Computer Interface> The system of this embodiment has a host computer 33 as shown in FIG.
and is connected to the image storage device 3. Figure 27 (
The interface with the host computer 33 will be explained using B).

The interface with the host computer 33 is performed by a GPIB controller 4310 connected by a connector 4580. GPIB controller is CPU
It is connected to the CPU 4360 via a bus 9610, and is connected to the host computer 33 according to a predetermined protocol.
It is possible to exchange commands with and transfer image data.

For example, when image data is transferred from the host computer 33 via the GP-IB, the image data is received line by line by the GP-IB controller 4310 and stored in the work memory 4390. The stored data is transferred from the work memory to the image storage memory AB,
The data is transferred by DMA to the CD and monitor display memory M, and data is received and received again from the GP-IB controller 431O, and the image is transferred by repeating the above process.

FIG. 42 is a block diagram showing the relationship among the work memory 4369, image storage memories AC, and monitor display memory M shown in FIGS. 27(A) and (B).

In addition, in FIG. 42, the reference numerals of each component of the embodiment have been changed. First, the host computer 33 sends the image size to be transferred. That is, input terminal 2401. GP-IB controller 240
2 from the host computer 33 to the CPU 2403 via
The image size will be loaded. Next, the image data is read line by line and stored in the -time work memory 2404. Image data stored in work memory is
A DRAM controller 2405 (hereinafter referred to as DMAC) stores image storage memory 2406. are sequentially transferred to the display memory 2407 (here, R is used for simplicity).
, G, and B are grouped together). The details will be explained below. The image storage memory 24.06 and the display memory 2407 are assigned addresses, for example, as shown in FIG. 43, and images are stored therein. In the figure, H
The lower address corresponds to the direction, and the upper address corresponds to the ■ direction. For example, point A is 100H in the I direction and 100H in the V direction.
If H, the address of point A will be tootoor+.

Similarly, the display memory also assigns lower addresses and upper addresses in the {circle around (2)} direction. Here, for example, images sent sequentially are stored in the image storage memory 2402 at the same size,
It is assumed that the image is reduced to 3/4 and transferred to the display memory 2407.

First, as described above, the image size and reduction rate of the image sent from the host computer are set in the DMAC, while the DRAM controller 24.08.

In 2409, the storage start address and the image size when reduced are set. After the above settings are completed, the CPU sends a command to the DMAC 2405 to start image transfer.

The DMAC 2405 gives an address and a signal to the work memory 2404 to read image data.

At this time, the address is incremented sequentially, and t
When the reading of H is completed, the next line is received from the host computer again and stored in the work memory. Meanwhile, at the same time, the DRAM controller 2408.240
9 is given "鄄1.[)W2" by the DMAC, and image data is sequentially written. At this time,
DRAM controller 2408. 2409 counts the number of input signals and sequentially increments the write address from the set top address. When writing in the H direction is completed, the address in the V direction is incremented, and writing is performed from the beginning of the next H.

When the above transfer is performed, the DMAC has a function similar to a rate multiplier for the DI, and therefore the IO
Reduction is performed by thinning out W. For example, if 3/4 reduction is set as described above, DMAC will thin out DI once every 4 times in the H direction, and in the As a result, reduction is performed by controlling writing to memory using σW.

FIG. 44 shows a timing chart. As shown in the figure, a read address is input to the work memory 2404, and data appears on the data bus by the ■ signal. At the same time, a write address is input to the storage destination address, and data is written from the tv times signal.

At this time, when the signal is thinned out by a factor of σW, the write address is not incremented and no writing is performed as described above.

(Description of Man-Machine Interface) As described above, the system of this embodiment (FIG. 1) can be operated from the host computer 33 and the operation section 20 of the color reader 1.

A man-machine interface using this operating section 20 will be described below.

By pressing an external device key (not shown) on the operation section 20 on the color reader I, the diagram A in FIG. 47 is displayed on the liquid crystal touch panel of the operation section 20.

FIG. 47 shows the color reader 11 to the image storage device 3.
3 is a diagram illustrating an operation when storing image data from a film scanner 34 or an Sv recording/reproducing device 31. FIG.

When the image registration key in FIG. 47A is pressed, the liquid crystal touch panel becomes as shown in C, and the input source displayed in the area surrounded by the broken line indicated by X in FIG. 47 is selected using the imperial key.

In this embodiment, there are three types of manual sources: a color reader 11, a film scanner 34, and an Sv recording/reproducing device 31, and these are selected by operating the circle key. This situation is shown below in Figure 0.

Next, press the image number key in Figure 0 to proceed to the next step.

In the case of FIG. D, an image is already stored at the designated image number. The image shown in D is shown in FIG.
Displayed by turning on the area shown in . Diagrams E, G, and H are determined by the input source selection (selected using the QIQ key) in Figure 0. If a color reader is selected, Figure E is selected, if film scanner 34 is selected, Figure G is selected, and Sv record is selected. When the playback device 31 is selected, diagram H is displayed.

When image registration of color reader I is selected, the state shown in FIG. 47E is reached. In this state, the pointing ben 421 of the digitizer 16 shown in FIG. 23 indicates the reading area of the document 999 on the platen glass 4 of the color reader 1. When this instruction is completed, the F diagram will be displayed and a diagram for confirmation will be displayed. If there is a change in the reading area, by pressing the turn key, you can return to diagram E and set it again.

When the reading area is OK, press the resetting key to display diagram G, and then set the amount of memory to be used.

The length of the bar graph of memory m in Fig. G changes depending on the attachment of the memory port (memories A to D in Fig. 27(A)) in the image storage device 3.

The image storage device 3 is the memory board (memory A-D) mentioned above.
) can be installed from one to a maximum of four.

In other words, the bar graph is the longest when four memory boards are installed.

The bar graph in Figure G indicates the memory capacity in the image storage device 2 and 3, and also sets the amount of memory to be used when registering an image. (On the EI day, the memory m to be registered and used is determined by the key, and by pressing the registration start key, the original scanning unit 11 in FIG. 1 scans 11 originals 999.

The image information from the document scanning unit 11 shown in FIG. The image data is output to the image storage device 3 via. The image storage device 3 displays the input image information on the monitor television 3.

The method of storing data in the memory of the image storage device 3 (FIG. 27(C)) is the same as that described above, and therefore will not be described here.

As described above, since the setting of the memory amount of the G diagram can be made variable, even when storing images of the same area, by increasing the set memory amount, it is possible to store images with high image quality.

Furthermore, by reducing the amount of memory, it is also possible to input a large number of images.

Next, the image registration from the film scanner 34 results in the display shown in Figure G, and the registration method is the same as that for the color reader 1, so a detailed explanation will be omitted.

If you select image registration from the SV playback device 31, the fourth
The display will be as shown in Figure H in Figure 7, and the AGC (Auto Gain Control) will check whether the rotation direction has been registered before registration starts.
0N10FF1 and field/frame settings. After the above settings, by pressing the registration start key, the image information from the Sv recording/playback device 31 is transferred to the image storage device 3.
The method of importing the image into the memory (FIG. 27 (C)) and storing the image in the memory is the same as that described above, and will therefore be omitted.

FIG. 48 is a diagram showing an operation method when printing a layout from the memory in the image storage device 3 to the color printer 2.

Figure 0 in Figure 48 is an operation display for selecting three types of layout patterns.

The fixed pattern layout prints out the contents of the memory of the image storage device 3 in a predetermined pattern.

In the free layout, an area to be printed is designated by the point ben 421 of the digitizer I6 shown in FIG. 23, and the memory contents of the image storage device 3 are printed out in that area.

The synthesis is performed at point Ben 4 of the digitizer 16 shown in Figure 23.
The contents of the memory of the image storage device 3 are written in the area designated by 21, and the images of the document 999 on the platen glass 4 of the color reader I are combined and printed out in areas other than the designated area.

If the fixed layout is selected, the number of print pages for fixed layout printing is set according to FIG. 48D. Each image area of fixed layout has A-P.
Image area names are given, and each area (A-P)
The image numbers corresponding to the images are set using FIGS. 48, E, and F, respectively. For example, when 16 screens are selected in the diagram shown in FIG. 48, the display shown in FIG. 48E is displayed.

For example, when the area shown at 8 in Figure B is selected, the display then moves to the view shown at F, and the number of the image to be formed in the set area is set using the numerical keys in Figure 48. By repeating this designation, multiple images can be registered. The number of images to be registered is automatically determined according to the type of fixed pattern selected in Figure D. When these settings are completed, the color reader's CPU
corresponds to the type of external device selected in Figure B, for example, in the case of Sv, an image corresponding to the desired screen selected in Figure F of the Sv player is stored in the storage device 3.

Next, the start key (not shown) of the operation unit 20 in FIG.
Prompts you to specify the corresponding image number. Then, by turning on the switch of the designated number, a hard copy with a fixed layout is outputted from the printer 2. Images output on 16 sides of the fixed layout print are printed in a layout as shown in FIG. 34.

The free layout print shown in FIG. 48 will be explained. In free layout printing, first, each area is set in order using the point ben 4.21 of the digitizer 16 shown in FIG. At the same time, select the image number to be printed in each area using the numeric keys in figure L.

After setting each area, by pressing the start key (not shown) of the operation unit 2o in FIG. 1, the memory contents of the image storage device 3 are printed out in the area set in FIGS. 1 and 2.

The composite layout shown in FIG. 48G has the same area settings as the free layout described above.

In areas other than the area, the image of the reflective original is output, and a color-in-color image is output.

FIG. 49 shows the case where the "monitor display" key is turned on in the state shown in FIG. The operation for adjusting the tint of each image when the image information stored in the image storage device 3 is printed out by the color printer 2 is shown.

When the monitor display key shown in FIG. 49A is pressed, a display as shown in FIG. The details are omitted as they have been described previously.

By pressing the color balance key in Figure 49A,
As shown in the figure, select the image number for which you want to set the color balance. When you select the image number, the LCD touch panel will display E.
The display will look like the one shown below, with bar graphs corresponding to red, green, and blue colors. When you press the red box key, the bar graph moves to the left side, which works to amplify the red luminance signal electrically, so the red component displayed on the monitor becomes faint (as shown in Figure 27 (E)). Look-up table (LUT) 4420R in monitor memory.

By changing the GB curve, the color tone of the monitor TV is changed and the look-up table (LUT) 4110A-R of FIG. 27(C) is used.

-G and -B curves are also changed. That is, communication is performed from the CPU of the color reader 1 to the CPU in the image storage device, and as a result, the rewriting of L[JT is performed by the CPU in the image storage device 3. By changing the two types of LUTs at the same time as described above, it is possible to print out an image from the color printer 2 with the same color tone as the image displayed on the monitor.

FIG. 50 is displayed when the "-O" key is turned on in the state shown in FIG. 47A. 50 is a diagram showing an example of the display when the rsVJ key is turned on in the display shown in FIG. 50B; FIG. That is, an operation for displaying the contents of the Sv disk reproduced by the Sv recording/reproducing device 31 on the monitor television 32 and an operation for printing out from the color printer 2.

Figure 0 in Figure 50 shows the operation for selecting index display or index print.

The Sv disk can record 50 fields in field recording and 25 frames in frame recording.

When you press the display start key in Figure 50, the first 25 screens of the SV disk will be displayed on the monitor in the case of field recording, and by pressing the display start key in Figure E, the second half of the 25 screens will be displayed on the monitor.
Display 5 screens. In such a case, the image storage device 3
The CPU within puts the Sv regenerator in a remote state.

In such a case, the CPU of the color reader 1 issues an instruction to the CPU in the image storage device 3 to sequentially store images of a plurality of tracks from the SV playback device in the memory. Then, CP[J in the image storage device 3 issues the following instructions to the SV playback device. That is, the first 25 screens of the 50 screens recorded on the SV disk are sequentially stored in the memory within the image storage device 3.

Note that in such a case, the image storage device 3 only needs to give a head movement instruction to the Sv player.

Specifically, before storing the image signal in the image storage device 3, the playback head of the SV playback device accesses the outermost track in the SV disk, and then the video image to be played back from the outermost track is accessed as described above. It is stored in the memory in the storage device 3. Next, the CPU of the storage device 3 outputs an instruction to the S2 player to move the playback head inward by one track.

The image storage device 3 then stores the video image again in the memory within the storage device 3. By repeating this operation, the image storage device 3 sequentially stores image signals in its memory and creates a multi-index screen in its internal memory. Further, in the case of frame recording, the entire SV disk is displayed by pressing the display start key shown in FIG.

Figures F and G in FIG. 50 are operations for printing out the contents of the index described above from Color Balance 2.

By pressing the start key on the operation unit 20 after making the settings shown in Figure F, the image storage device 3 first starts the Sv recording/playback device 31.
25 screens worth of images are stored in memory, and then,
An index print is performed by a color printer 2 via a color reader 1. Since the diagram G is similar, the explanation will be omitted.

As described above, by performing the operations shown in FIGS. 50F and 50G, image registration and layout printing can be easily performed.

Control by Host Computer> The system of this embodiment has a host computer 33, as shown in FIG. 1, and is connected to the image storage device 3. The interface with the host computer 33 will be explained using FIG.

Interfacing with host computer 33 is performed by GI)-1B controller 431O connected by connector 4580. The GP-IB controller 4310 connects to the CPU 4360 via the CPU bus 9610.
It is possible to exchange commands and transfer image data with the host computer 33 using a predetermined protocol.

The image data of the color reader l and the Sv recording/reproducing device 31 is sent to the host computer 33 by the GP-IB controller 431O connected by the connector 4580, stored in the storage area of the host computer 33, and processed for enlargement/reduction processing. , Cutting out a portion of image data and laying out multiple image data have been conventionally performed. However, in that case, color image data 1
Since the capacity is quite large, it takes a very long time to transfer data between the color reader ISv recording/reproducing device 31 and the host computer 33 even through a general-purpose interface such as GP-iB. Therefore, instead of directly sending the input image data to the host computer 33, a predetermined command is sent from the host computer 33 to the GPrB controller of the image storage device 3, and the CPU
The 4360 decodes the command and reads the color reader L or Sv.
By controlling the input image data of the recorder/player 31 and specifying only the truly necessary image area, other parts are not stored in the memory, making effective use of the memory and transmitting the image data to the host computer 33. There is no need to transfer.

Furthermore, the image storage device 3 can store the input image data in the image memory 4060 .
It is possible to store multiple image data in 1-R, 4060A-G, and 4060A-B, and the host computer 33 performs image processing such as layout and enlargement/reduction of each image.
The CPU 4360 of the image storage device 3 performs the processing/instruction on the input image data simply by an instruction from the host computer, without having to perform the processing/instruction on the input image data. It does not take much time to transfer, making it possible to shorten processing time.

As described above, how does the image storage device 3 store input and output images according to instructions from the computer 33?
We will explain in detail how to handle it.

All input and output image data stored in the image storage device 3 is handled within the image storage device as an image file.

Therefore, the image registration memory memory A (4060A
), Memory B (4060B), Memory C (4060C
), the memory D (4060D) functions as a RAM disk, and at that time, the image files to be stored are stored in the image file management table 43 using the file name as a key.
61 (Fig. 51).

When an image file is registered and stored in the image storage device 3 functioning as a RAM disk, the minimum image file management unit is a basic block obtained by dividing each of the registration memories 7A to 7D into a plurality of blocks.

The CPU 4360 can also combine several of these basic blocks using the image file management table 4361 and manage them so that they constitute one large image file. At that time, all management data such as the image file name, its image data size, file protection, and registration memory configuration are stored in the image file management table 4361 at the time of registration.

Generally, when an image is input from the reader 1 as described above, the image storage device 3 reduces the image to the same size or reduces it and registers it as an image file in the image storage device. Therefore, if you increase the size of the image to be registered and register it, it will approach the original size of the original image from reader 1, and the reduction ratio will be small (so when you output the registered image file to printer 2, etc., the quality will be lower. improves.

The image file name that the CPU 4360 uses as a key when image data is input from an input device such as the reader 1 and the computer 33 is determined by an instruction from the computer 33.
File names are given in the structure shown in Figure 56. This file name clarifies the management of image data between the computer 33, the image storage device 3, and the input/output device, and allows the computer 33 to attach any image file.

The image file name consists of eight characters (AS (jl code)) of the image file name and an extension indicating the type of image of the image data.

The type of image to be handled is distinguished by the extension, and the registration memory 40 is structured according to the image type.
60 and will be managed.

The image type is RGB type luminance image data when the extension is ",R", CMYK type density image when it is ",C", and 8-bit palette type 167 when it is ",P".
This refers to image data that can be set to any 256 colors out of 00,000 colors. Further, when ",S" is a special file, it indicates an image file that has a special meaning within the image storage device 3 and has a special structure.

The coordinate system for handling images in the image storage device is composed of an origin serving as a reference, an X direction representing the width direction of the paper, and a Y direction representing the height direction (FIG. 52).

The image storage device processes data from each input device within the image storage device coordinate system and manages various image data.

Analog input terminal (RGB, video) (4500, 4
510°452OR, G, B, S) and register it in the registration memory, the input image is
The image will be registered as shown in Figure 3. The input image at this time has a size of 600 pixels in the X direction (width) and 450 pixels in the Y direction (height).

The coordinate system of the digitizer 16 is as shown in Figure 54 when viewed from the image storage device. The coordinate system of the image storage device and the digitizer coordinate system are the same, and their respective origins correspond to the X and Y directions.

When viewed from the image storage device, the coordinate system of the reader l is the fifth
It will look like Figure 5. The origin, X direction, and Y direction of the coordinate system of the image storage device and the reader coordinates correspond to each other.

Next, data exchange via G P-I B will be explained.

The types of data exchanged between the image storage device 3 and the computer 33 through the GP-IB 4310 are classified as follows.

■Command (instruction) Command from the computer 33 to the image storage device 3 ■Various arguments accompanying the parameter command ■Data section/image data Binary data/extension data of color (monochrome) images such as RGB, CMYK, etc. To the image storage device 3 This is data that is transferred when obtaining set data or rewriting setting data.

■Response data: ACK/NAK, response with additional information (RET), i.e.
This is a response returned from the image storage device to a command.

The above four types of data are exchanged between the computer 33 and the image storage device 3 via the GP-IB controller 4310.

These four types of data will be explained below using FIG. 57.

As shown in FIG. 57, the image storage device 3 and each input/output device reader 11 analog input 4500, 4510° 452
R, G, B, S, image data handled between the printer 2 and between the image storage device and the computer 33 are as follows:
It is classified into the following four types.

■ RGB data type ■ CMYK data type ■ 8-bit palette data type ■ Binary bitmap data type These image data types are distinguished by the extension part of the image file name described above. For example, when the image file name accompanying the 5CAN command on the computer 33 side has an extension of ",R" indicating RGB image data, the CPU 4360 of the image storage device 3 responds to the input from the input device. , is input controlled as an RGB-based luminance image, and is registered as RGB type image data in the image storage device.

Figures 60 and 61 show the structure of RGB type image data.

In the image storage device, as shown in FIG. 27(A), the basic blocks of memories A-D (4060A-D) of the registration memory are configured as shown in FIG.
60A), the basic blocks of 2 images (4060A-R), 6 images (4060A-G), and 8 images (4060A-'B) are combined. The image structure of the image is the number of pixels (dots) of the horizontal length (width) and the vertical length (height).

Specifically, it is an RGB color image, and each pixel of R, G, and B has a depth of 8 bits (1 byte), and is composed of 3 frames of R, GB.

Therefore, 1 pixel on 2 sides provides 256 gradations (0 to 255), and 3 sides of R-G-H provide 256 x 256 x 2
It has a data structure of 56ζ16.7 million colors.

Note that 0 represents low brightness and 255 represents high brightness.

The data structure is arranged in the order of data starting from the upper left on two pages, and this structure continues in the order of RGB.

Image data is transferred between the image storage device 3, the input/output device, and the computer 33 using a transfer format as shown in FIG. In other words, data is transferred in frame sequential order.

Figures 62 and 63 show the image structure of CMYK type image data and its transfer format. C is cyan, M
stands for macenta, Y stands for yellow, and K stands for black. In such a case, the basic blocks of memories A to D (shown in FIG. 27A) of the registration memory in the image storage device 3 are made into an image configuration as shown in FIG. 31, and basic blocks are assigned to each.

Specifically, it is a CMYK color image, C, M, YK.
Each pixel has a depth of 8 bits (1 byte), which consists of four frames: C, M, and Y.

Therefore, 256 gradations can be expressed with one pixel on the 0th plane, and the same applies to the M, Y, and other planes.

0 represents low density and 255 represents high density.

The data structure is arranged in order from the top left on page 0, and this structure is CM Y
Continued in the order of K (.

Figures 64 and 65 show the image structure of 8-bit palette type image data and its transfer format.

Memories A-D (27th memory) of the registration memory of the image storage device 3
The basic blocks in Figure A) are configured as shown in Figure 64, and the basic blocks are allocated.

The image structure has a depth of 8 bits (1 byte) per pixel.

The 8-bit data value of 1 pixel corresponds to the color index No. of the color palette table 4391, as shown in FIG. 66, and can be colored arbitrarily by the user.

Therefore, it is possible to express 256 colors per 1 pixel.

FIG. 85 shows the relationship between image data and color palette.

The data structure is arranged in order of data starting from the top left of the image.

67 and 68 show the image structure of binary bitmap type image data and its transfer format.

The binary bitmap is stored in memory E (27th
Figure A).

This image data is a special file with the image file name extension “S”, and the image file name is “B”.
ITMAP, S'' and is registered in memory E (FIG. 27A) in which only binary bitmap types can be registered.

In the memory E (FIG. 27A), since the basic block constitutes the entire memory, multiple registrations cannot be performed.

Binary bitmap type image data has an image structure with a depth of 1 bit per pixel.

Therefore, there are two expressions per pixel: "0" and "Vi". "0" means white (not printed) and "Vi" means maximum density (
black].

The data structure is such that data is set in 1 byte for 8 bits, or 8 pixels, starting from the top left of the image, so binary bitmap type image data is
It must be a multiple of 8 in the d t h direction. The height direction is arbitrary.

Since the image file size is set in pixels, the amount of data to be transferred is as follows.

<width>: Width of the image file <
height>: Height of the image file (height
t) 8: 8 pixels equals 1 byte of data.

Next, the structure of response data in response to command transmission from the computer 33 to the image storage device 3 will be explained using FIG. 69.

・Basically, image data is excluded (the following types of response data apply.

FIG. 69 shows the structure of response data.

As can be seen from the figure, which response data is received differs depending on the type of command.

ACK and NAK are paired, and most commands use one of them as response data.

- ACK type response data is an affirmative response to each command, and indicates that the command was normally transmitted and decoded to the image storage device 3 side. The 3-byte fixed value/NAK type response data, where the first byte is 2EH and the remaining 2 hides are OOH, is a negative response to each command, and is a response when some error occurs, and the first byte is 3DH, and the remaining 2 hides are OOH. 2 bytes are an error code.

(Error code) = (upper byte)
EX) + (lower byte) RET type (response with attached information) response data is a response to a command from the computer 33, and is sent from the image storage device 3 with necessary information attached.The configuration is as follows. The total length is 8 bytes, and the first byte is a fixed value of the header (02H).Following the header, the 1st to 7th data continue by 1 byte, and the content of each data is the command It depends.

The commands are for the computer 33 to control input/output of image data, image file management, etc. to the image storage device 3, and there are commands as shown in FIG. 70.

Commands are divided into those that perform a function with a single command and those that require parameters following the command.

FIG. 58 shows an example of the configuration of command parameters.

Since commands and parameters are sent as character strings to the image storage device 3 via the GPIB controller 431O, if there is a numerical value in the parameter section, it is necessary to convert that numerical value into a character string representing an IO base number. be.

Also, among the parameters is a character string indicating the image file name.

These commands cause image data to be sent to the computer 33, image storage device 3, input device 1, output device 2.
．． FIG. 59 shows how the flow flows between the 32 devices.

Commands from the computer 33 to the image storage device 3 are classified into seven types. (Figures 70 to 72) ■Initialization command: Performs various initializations.

■Input/output selection command: Select the input/output device.

■I/O mode setting command: Set conditions for image input/output.

The 5AREA command is a command for setting the input signal from the color reader 1 in the same way as the DAREA command. The input/output range setting using 5AREA/DAREA is performed by the system controller 4210.

Set the scaling when outputting the DMODE command (to the area specified by the DAREA command) to 4150-0 to 41.
This is a command to set the enlarging/interpolating circuit of 50-3.

The 5M0DE command is a command by which the system controller 4210 controls read scaling when inputting to the area specified by the 5AREA command.

The ASMODE command sets in the CPO 4360 that the system controller 421O and the counter control 9141 decide whether to input the image as a field signal or a frame signal from the analog input terminal.

Note that the field signal and frame signal are well known in television, so their explanation will be omitted.

The input/output execution command will be explained using FIG. 76.

The C0PY command reads the reflective original of reader l,
without registering it as an image file in the image storage device 3.
This is a command that causes the printer 2 to output directly. At that time, the number of sheets to be output to the printer 2 can be specified using the /( parameter shown as <Count>.

The 5CAN command causes the CPU 43 to

At that time, the CPU 4360 stores the image file name, image type, image size, and information in which image memory it is registered in the image file management table 4361 shown in FIG.
Set to .

The PRINT command, contrary to the 5CAN command, is a command that specifies image file data already registered in the image storage device 3 using a parameter indicated as <filename>. Data from memory 4060 is output to the printer via video interface 201. At that time, the number of times specified by the variable number indicated as <count> is repeated and output to the printer.

The MPRINT command is a command that virtually outputs image file data specified by a parameter indicated as <filename> registered in the image storage device 3. This means that when multiple layouts are combined and output, multiple image files are sequentially specified using this command, and the CPU 4360 stores the image file name specified using the MPRINT command in the memory 4370 for each image file. PRINT or C0P

The availability of reservation is set in the RET type response data, and the remaining capacity after the reservation is sent as RET response data to the other party that sent the DKCHECK command, for example, the computer 33, via GPIB.

For example, the display shown in FIG. 47G can be produced by such a command or specific code.

FNCHECK: I mant checks whether the image file specified by the parameter indicated as <filename> exists in the image file management table 4361, sets presence/absence in the RET response data, and returns it to the computer 33.

The FNLIST command is a command that sends the contents of the current image file management table to the computer.

The REN command is a command for changing the name of an image file set in the image file management table, and is a command for changing the image file name <Sfilename> before the change to <Dfilename> after the change.

Next, file operation commands that involve inputting and outputting image data will be explained using FIG. 78.

The LOAD command is a command that transfers the data of the image file specified by the parameter indicated as <filename> among the commands registered in the image storage device from the image memory 4060 to the computer 33 via the GPIB.

The 5AVE command is the opposite of LOAD, and loads the data of the width x height image size on the computer,

FIG. 80 shows other commands.

The MONITOR command outputs analog outputs 4590R, G, B, S for the analog input specified by the 5SEL command according to the <type> parameter.
The display controller 4440 is set for through display in which data is directly streamed and displayed. In addition, type
Examples of variables include "0" (through display is set), "
1" (sets monitor mute), etc.

Furthermore, the MONITOR command has a lower priority than other commands (the through display setting is canceled by other DSCAN or 5CAN commands).

The PPRREQ command is sent by the CPU 4360 to the control unit 1 via the video interface 201.
3, information on the paper size currently set in the color printer 2 is obtained, and paper discrimination data is transmitted to the computer side.

Similarly to the above, the PPR3EL command sends the command to the control unit 13 specified by the <no> parameter.
This is a command for selecting from among a plurality of paper trays, and is output to the color printer 21 via the image storage device 3.

The 5ENSE command is used to check the status of the image storage device 3, color reader 11, color printer 2, etc.
This is a command for the U4360 to communicate with the control unit 13 via the video interface, obtain the data, and send the data to the computer side.

Next, a procedure for transmitting commands from the computer 33 to the image storage device 3 will be described.

The basic commands for inputting and outputting images can be broadly divided into (i) input/output selection commands 5SEL, DSEL (ii) input/output status setting commands 5M0DE, 5AREA, DMODE, DAREA.

RPMODE, ASMODE (iii) Input/output execution commands 5CAN, DR3CAN, PRINT, MPRI
N.T.

DRPRINT becomes.

As shown in FIG. 82, there is a basic procedure for transmitting commands for inputting and outputting image data.

First of all, use the input/output selection command to select the input/output device.
PU4. ．． 360 analyzes the command and returns response data ACK/NAK to the computer 33.

Next, the computer 33 sends the input/output status setting command to the image storage device 3, and sends the result to the CPU 4360.
returns ACK/NAK response data to the computer 33 in the same manner as above.

The input/output status setting command loses its effect and returns to the default status when the input/output execution command is executed. Therefore, if the input/output execution command is executed without executing the input/output status setting command, the default value is set for the input/output status setting. If you want to set a specific input/output status when executing input/output, you need to execute the input/output status setting command for each input/output execution (for each basic form).

Then, the CPU 4360 sends an input/output execution command to actually execute input/output of image data, and in response, returns RET type response data and sends an acknowledgment (ACK).
In this case, actual input/output of image data is performed between the input/output device reader 1, 5V31, printer 2, monitor 32, etc. and the image storage device.

This input/output is the same as in the embodiment described above, and a description thereof will be omitted.

The CPU 4360 uses the image file management table 4361 to check the image file attributes in advance in response to commands related to image file registration from the computer, and to check the memory capacity (memories A to D) in which files can be registered (Fig. 27). It is possible to perform processing such as checking A)) in advance and notify the computer 33 side.

The command for pre-checking this image file is:
There are FNCI-IECK and DKCHECK commands.

The procedure for checking this image file is described in Section 82.
As shown in Figure 83, first, the existence of the designated image file and its file attributes are sent to the computer 33 side as RET type response data, and the remaining capacity of the image file or the desired image A response indicating whether the file size can be secured is returned as RET data.

This basic form of file check can be incorporated into the above-mentioned basic form of human output commands, so that it is possible to check and respond to image files in advance before executing input/output.

Next, the composition of image files will be explained.

To combine multiple images registered as image files in the registration memory 4060 of the image storage device 3 and output them to the color printer 2, use MPRINT from the computer side.
This is possible by sending a command to the image storage device 3.

The MPRINT command specifies an image file name registered in the image storage device as an argument. The CPU 4360 analyzes the command string of the MPRINT command and temporarily registers the file name on the memory 4370.

By sequentially transmitting this MPRINT command string for multiple layouts from the computer 33, the designated file name is temporarily registered on the RAM, and the computer side transmits the PRINT command string when the last image of the multiple layouts is received. CPU 4360 uses this PRIN
When the T command is analyzed, MPRINT on RAM is
C in the order of the image file names sent to the commands.
Based on the image file management table 4361, the PU transfers designated image data from the image memory to the color printer and outputs it. The combined output at that time is as described above.

Order of MPRINT transmission from computer and PRIN
As shown in FIG. 88, in the order of image composition using the T command, priority is given to the image specified first.

In addition, in order to synthesize a special file that is a binary bitmap memory (memory in FIG. 27A) and an image file registered in the image storage device, the above-mentioned MP
If you set the special file name "BITMAP, S" on the computer side among the multiple specified image file names of the RINT and PRINT commands and send it, the CPU
Similar to the above, 4.360 combines a plurality of image files and binary bitmap data. In addition,
In this embodiment, the binary bitmap image is basically black where the dots are "1", and where the dots are "0", the output is switched so that priority is given to outputting other image files. Such an example is shown in FIG.

Such switching is performed by the video interface 2 of the reader l.
Since 01 is used, the configuration of the image storage device is simplified.

As an image compositing function, it is possible to combine and output the image file, the binary bitmap "BITMAP, S" special file, and the reflective original of the reader 1, and perform the compositing operation described above. .

The above-mentioned operations based on commands from the computer are performed by M
It can be executed using the PRINT command and C0PY command.

The CPU 4360 specifies multiple image files using the MPRINT command, and finally sends the C0PY command to complete the process.The CPU 4360 then instructs the CPU of the color reader to perform a copy operation, and then specifies the image files and files using the MPR[NT command. It is possible to combine and output the reflected originals on the reader section.

At that time, if you specify the image file "BITMAP, S" in MPRINT, you can also combine it with a binary bitmap.

In this embodiment, reader 1 is
Since the reflection original of the copy automatically has the lowest priority, it can serve as the background of the image.

The order of command transmission from the computer and the actual output results from the printer are as shown in FIG.

In this embodiment, as shown in FIG. 79, the color adjustment function uses the PALETTE command and BALANC as commands from the computer corresponding to the color palette function, color balance function, and gamma correction function.
There are E command, GAMMA command, and BrTCOLOR command.

The color palette is used to set colors for 8-bit palette type or to color binary bitmap type image data, as described above.

To do this, set color data to the palette number in the color palette. Specifically, 256 color data can be set, with 8 hits of data for each of RGB.

By making the color data set in the color palette 4362 in the image storage device 3 the same as the color palette in the host computer, the colors of the image output by the color printer l can be changed via the image storage device 3. It can be the same as the host computer.

The color palette table in the image storage device 3 is PAL.
A palette table can be set for each image file registered in the image storage device 3 using the ETTE command. Therefore, when outputting an 8-bit palette type image file with the extension "P" using the PRINT or MPRINT command, set the PALETTE command from the computer, and then output 256x3 (768) bytes as shown in Figure 91, for example. PRINT to set the RGB palette table data of
/MPRINT When the command is executed, R, G, B of the currently set palette table 4362
The components are LUT4110A-R and 4110A-G, respectively.
.

4110A-B, and perform calculations for converting brightness to density on each table.

At that time, the image file data of the palette type specified by the PRINT/MPRINT command is stored in the LUT4110A-R, 4110A-G with the palette table set.
The luminance information of the 8-bit palette is converted into density information via 4110A-B and sequentially outputted to the above-described image output system, and then outputted by a color printer.

8-bit palette type images are stored in the work memory 439 when sent from the computer via the GP-IB.
0 one line at a time, and the same data is set in the registration memories 4060-R, 4060-G, and 4060-B by DMA, and then sequentially (returned).

A maximum of 16 8-bit palette tables can be set using the PALETTE command, and can be set for each 8-bit palette type image data when compositing multiple layouts.

MPRINT multiple 8-bit palette type images
Before printing virtual output using the command, P A L E T T E
The CPU 43 sends the color palette data (768 bytes) to the memory 4370 of the image storage device 3 according to the command.
60 temporarily registers.

This is repeated for multiple 8-bit palette images to be layout composited, and when the final image is output, the PRIN
Execute the actual output using the T command.

In response to the PRINT command, the image storage device 3 reads from the memory 4370 the palette table of the 8-bit palette image according to each MPRINT command that has been set up to that point.
When sequentially outputting a composite image, it is possible to set a color palette table 4362 for output and composite a plurality of images and output the composite image to the printer 2 as described above.

Next, set the color balance by RGB type and CMY
It is possible to set two types of color balance for K type.
They can be distinguished by the ype parameter. This setting can be made using the BALANCE command.

RGB color balance is LUT4110A-R.

The slope of brightness is set for 4110A-G and 4110-B by the values of ±50% of the C1, C2, and C3 parameters of the BALANCE command, and the brightness is converted into density.

For CMYK color balance, the gradient of density is set for LUT4200 by the values of CI, C2°C3, and C4 parameters of the BALANCE command ±50%.

Each image file data is converted by the above LUT,
Image quality can be changed from low to high brightness and low to high density.

The GAMMA command is set to RG by the type parameter.
For I3 type image file data, γ = 0.45 correction data that takes into account the light emission characteristics of CRT,
Colors can be reproduced on a CRT using two printers.

') The control unit 13 sends 3-byte color data of RGB components (repeat sequentially when multiple areas are specified by the BITOOLOR command), and sets those parameters in the programmable compositing unit 115. , it is possible to color a designated area with a designated color when outputting a binary bitmap to a color printer.

After setting the area and color on the control unit 12 side in this way, the CPU 4360 of the image storage device 3
“BIT” by RINT or MPRINT command
Binary bitmap data of MAP, S'' (Figure 27 (A)
) memory E) can be colored and outputted via a video interface by a command from a computer.

Coloring is performed on the portion of the binary bitmap where the bit is "1".

The remote function allows the color reader/color printer and the image storage device 3 to be set in a state where they can be controlled by the host computer.

The above-mentioned REMOTE command is a command from the computer that performs remote control, and four states can be set using this command (FIG. 92).

In the system remote state, the color reader/color printer and image storage device 3 can be controlled by commands from the computer.

Only the image storage device 3 can be controlled by commands from the host computer 33.

At this time, the color reader/color printer can perform copying operations by itself as a copying machine.

The local state is a local state (a state in which control cannot be performed) from both the host computer and the color printer/color reader. The device enters the remote state when instructed by the REMOTE command, whichever comes first.

In the copying machine remote state, the image storage device 3 can be placed in the remote state and controlled by an instruction from the operation section of the color reader l. At this time, commands from the computer cannot execute the functions of the image storage device 3.

These remote/local states can be specified by the type parameter of the REMOTE command from the host computer 33.

The type parameter of the REMOTE command allows C
The P U 4.360 communicates with the CPU 22 of the control unit 13 of the color printer 2 and the color reader I via the video interface 201.
The four remote/local states mentioned above can be instructed from the computer.

Next, some examples of the command transmission procedure described above are shown in FIGS. 84 to 87.

FIG. 84 shows a procedure for registering image data from the input device to the image storage device 3 as an image file using the 5CAN command. The basic part of the file check shown in the figure can be checked in advance by incorporating the procedure shown in FIG. 83, as described above.

FIG. 85 shows an example of a procedure for outputting image data of an image file already registered in the image storage device 3 using a PRINT command.

FIG. 86 shows a procedure for inputting image data from the input device to the image storage device, registering it, and transferring the image data to the computer 33 using the DR3CAN command.

Figure 87 is the reverse of the DR3CAN command in Figure 86,
This is an example in which image data on the computer 33 is outputted by an output device.

Next, we will give an example of an actual command.

As an example of outputting a single image, FIG. 93 shows an example in which an image in the host computer is output to a color printer. For example, an RGB type image of 1024 x 768 pixels is 277 x 190 pixels from the top left (to, 10) mm position of the paper.
An example of centering and printing within a range of mm will be described.

As an example of outputting a layout of multiple images, this is an example of laying out two RGB type image data in the post computer 3 on one sheet of paper and outputting it on the color printer 2 (
Figure 94).

In this example, two RGB type images of 1280 x 1024 pixels and 1024 x 768 pixels are respectively centered within the range of the figure and printed out.

When outputting multiple images, there are cases where each image is registered from the host 3 to the image storage device 3, virtual output is performed, and output to the printer 2 (as shown in FIG. 96), and the image data is first sent to the image storage device. There are cases where the virtual outputs are registered and all virtual outputs are output at once (as shown in FIG. 95). Both output results are the same.

Further, FIGS. 97 and 98 show examples of importing images from the reader 1 to the host 3.

In such a case, first, for example, an area equivalent to A4 size (297 x 210 mm) on the reader 1 is read as RGB type image data with a size of 1 000 x 707 pixels, and the data is imported into the host computer 3.

As described above, according to this embodiment, the computer 3
3, instructions (commands) between the image storage device 3 and the computer 33 without holding image data for input/output.
Image data can be input and output simply by exchanging
Data transfer between the computer and input/output devices (reader 11 printer 2, etc.) can be reduced.

In the above description, in this embodiment, a so-called flatbed sensor using a color line sensor was used as a means for photoelectrically converting the target image, but the present invention is not limited to this, and for example, a spot sensor may also be used. , and is not limited to the type of sensor.

Further, in this embodiment, a color printer that forms a full-color image by so-called field-sequential image formation is used as a means for image formation, but such a color printer may be a printer other than a field-sequential printer, such as an inkjet printer. However, a thermal transfer type printer or a printer called Cycolor may also be used.

In addition, in this embodiment, a host computer, an image storage device,
Since the color readers communicate with each other as independent devices to realize the various functions described above, a new system can be provided.

According to this embodiment described above, a communication means is provided between each device, so that operations can be performed from one device, for example, all devices can be activated by a single copy button on a copying machine. . Furthermore, it is possible to select a desired screen frame from among a plurality of screens reproduced from the SV player by using the keys on the display of the operation unit 20 on the copying machine side, improving usability.

Further, in this embodiment, the frames of the SV playback machine are selected, but the source of the image signal may be another device, such as a VTR or a video disc.

Further, in this embodiment, the image storage device 3 is a color reader l.
Although it is constructed separately from the color printer 2 and the color printer 2, it goes without saying that they may be integrated.
