This is a control unit that controls the entire reader 1, and performs display on the operation panel 20, human key control, control of the video processing unit 12, etc. via the bus 508. Further, the position of the document scanning unit 11 is detected by position sensors Sl and S2 via signal lines 509 and 510.

Furthermore, the stepping motor drive circuit 15 that pulse-drives the stepping motor 14 for moving the scanning body 11 is connected to the halogen exposure lamp 10 by the exposure lamp driver 21 via the signal line 504.

Further, 20 is an operation section of the color reader section l, which includes a liquid crystal display panel that also serves as a touch panel and keys for giving various instructions. Note that display examples of such a display panel are shown in FIG. 47 and subsequent figures.

The color image signal read by the above-mentioned original scanning unit 11 during original exposure scanning is sent to the sensor output signal 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.

The color image signal input to the video processing unit 12 is separated into three colors, G (green), B (blue), and R (red), by the sample and hold circuit S/H 43. Each separated color image signal is converted from analog to digital by an A/D converter 44 to become a digital color image signal.

In this embodiment, the color reading sensor 6 in the document scanning unit 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 1, 3. The reading position deviation of 5 channels is corrected. The positional deviation correction flow signal from the deviation correction circuit 45 is input to the point correction circuit/white correction circuit 46, and color reading is performed using signals corresponding to the reflected light from the white plate 8 and black plate 9 described above. Dark-time unevenness of the sensor 6, unevenness of the light amount of the halogen exposure lamp 10, and variations in sensor sensitivity are corrected.

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.

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

Furthermore, 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 = 00H, black = FFH (image source that is converted and further 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 have different gamma characteristics depending on the sensitivity and exposure status of the negative film, positive film, or film, as shown in Figure 7(a). , (b
), it has multiple LUTs (look-up tables) for logarithmic conversion, which are used depending on the purpose.

Switching is done using signal line I! go, fgl, and 1g2, and is performed by inputting an instruction from the operation unit or the like as the I10 port of the CPU 22. Here each B, G, R
The data output to corresponds to the density value of the output image, and corresponds to yellow and magenta for each signal of B (blue), G (green), and R (red), respectively.

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. In addition, in the figure, R
, G, Y, and M are shown.

Therefore, for each color component image data Yi, Mi, Ci, masking correction is known in which color correction is performed by calculating a linear equation for each color.Furthermore, by Yi, Mi, Ci, Min (Yi, Mi, Ci) (Yi,
The minimum value of Mi, Ci) is calculated, and this is sumi (minimum value of Mi, Ci).
As shown in Fig. 10(a), an operation of adding black toner (smear removal) and an undercolor removal (UCR) operation of reducing the amount of each coloring material added according to the added black component are also performed. , a color correction circuit 49 that performs masking, smearing, and UCR.
The circuit configuration is shown below. The characteristics of this configuration are: ■ It has two masking matrices, and can be switched at high speed with one signal line "110." ■ One signal line "110" indicates whether UCR is present or not. Can be switched at high speed (2) It has two circuits for determining the amount of smear, and can be switched at high speed at "110".

First, prior to image reading, a desired first matrix coefficient M H and a desired second matrix coefficient M2 are set via a bus connected to the CPU 22 . In this example, Ml 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 matrix M1, the switching signal MAR
When EA566="l" is selected, the matrix M2 is set to "O".

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

The UAREA 572 is configured such that UCR (undercolor removal), presence and absence can be switched at high speed with "110".

The A inputs of the multipliers 66a, 66b, and 66c each have (aYl, -bMl, -CC1),

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

This is a configuration that can be applied when synthesizing as in this embodiment. Note that these area signals MAREA, UAREA, KA

Next, No. 1111. describes a black character processing circuit that improves black reproduction of black characters and thin lines in a document, and color bleeding at the edges of black characters and black lines. This will be explained according to FIG.

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 thin line), luminance signal Y1 color difference signal 1. Q is calculated by a Y, I, Q calculating circuit 70 (FIG. 11).

The luminance signal Y575 is used to extract the edge signal (
A line buffer circuit 7 for 5 lines is used to calculate a 5×5 matrix using a known digital second-order differential circuit 72.
1, and the Laplacian operation is performed in the arithmetic circuit 72 as described above. That is, when the input luminance signal Y is a step-like input (for example, a character part) as shown in i) of FIG. signal). Lookup tables LUTA73a and LUTB73b are lookup tables for determining the printing amount (for example, toner amount) at the edge portion of black characters (or thin black lines), and are as shown in FIGS. 12(a) and 12(b), respectively. It consists of a lookup table with characteristics. That is, when LUTA acts on the edge signal 576, the amplitude increases as shown in FIG. 12(d)(iii), and this determines the amount of black toner at the black edge portion, as will be described later. Furthermore, when LUTB acts on the edge signal 576, the absolute value appears negative, which is due to the Y
, M, C (yellow magenta, cyan) toner amounts are determined. This is a signal as shown in FIG. 12(d) (iV), and when it passes through the smoothing (averaging) circuit 74, it becomes a signal as shown in FIG. 12(V).

On the other hand, the achromatic color detection circuit 75 outputs, for example, the 12th
This is a circuit that outputs a signal according to the characteristics shown in the figure.This signal is selected by the selector 76 during black toner printing by the signal 577 which becomes "1" when printing the black toner, and the signal 577 becomes "1" when printing the black toner.
78 and is multiplied by the aforementioned signal 579 (FIG. 12(d) (iii)) which determines the amount of black toner in a multiplier 77, and then added to the original image signal in an adder 78. .

On the other hand, when printing with Y, M, and C (yellow, magenta, and 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 "1n" to the multiplier, and the selector 79 outputs "1n" to the LUTB 73.
The signal obtained by smoothing the output from 6 (Fig. 12(d)
(V)) is output, and the adder 78 outputs the voltage shown in FIG. 12(d).
The same signal as (V) is input, and the signal only 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 sob becomes "1" 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 = "1") S input = "1"
”, and the A input, that is, 579 (Fig. 12(d) (
iii)) is output and the black edges are emphasized. Y, M
, C) Signal 581 when printing Qi (when 577="O")
= “l”, so if it is an achromatic color, then <Y, M,
To reduce the amount of toner in C (S input is selected and (V) in Fig. 12(d) is output, but in the case of chromatic color, the signal 5 is
81=0, therefore 581=11, i.e. selector 7
The S input of 9 becomes 1 and A is selected, as shown in Fig. 12(d).
The signal (iii) is output to the adder 78, resulting in 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 "l", and the 12th
The LUT clamped to zero at A'B' in figure (a) is
Furthermore, when the concentration is below a certain level, that is, when the output of the comparator 81 is “On,” the LU is clamped to zero at A and B.
By selecting T, the noise removal effect is changed depending on the density range.

Furthermore, the output 583 of the AND gate 82 is obtained by further improving the edges of black characters, and when printing Y, M, and C, the output 583 (B
This is a signal for switching to select input .) and 585 for other inputs. Signal 5 input to AND gate 584
86 is a LUTC (FIG. 12(C)) for the edge signal described above.
) is binarized by the binarization circuit 80a.In other words, when the absolute value of the edge signal is greater than or equal to a predetermined value, it becomes "BI," and when it is less than, it becomes "0." , 5
87 = "1" 581 = "1", 588 = 'L' is achromatic color and when the edge signal is large, that is,
This occurs only at the edge of the black signal, and only when printing with Y, M, and C toners. Therefore, at this time, as explained earlier, only the parts corresponding to the black edges from the original signal are Y and M.

The signal determining the amount of toner C is subtracted, and the remaining signal is smoothed by the averaging circuit 84, and when the signal ER="1" is outputted to the selector 83 through the selector 83. Otherwise, the normal edge-enhanced signal 585 is output at output 589.

The signal ER is controlled by the CPU 22, and when ER="1", the output of the averaging circuit 84 is output to the output 589, and ER="0".
”, “0” is output to the output 589. This makes the signals of the color toners (Y, M, C) around the edges of black characters completely “0” to further eliminate the color blur. , these are selectable configurations.

FIG. 13 shows area signal generation (
The aforementioned MAREA566, UAREA572. KARE
A573, etc.). The area refers to, for example, the shaded area in FIG.

It is distinguished from other areas by a signal such as EA.

Note that this area is specified by, for example, the digitizer 16 or the like.

FIGS. 13(a) to 13(d) show the generation position 2 of this area signal.
This shows a configuration in which the number of sections having a section length of 2 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
In order to obtain AO~AREAn, an n-bit configuration RAM is used.
(Fig. 13(d) 85A, 85B).

Now, the area signal AREAO as shown in FIG. 13(b).

and AREAn, address x of RAM
Set "1" to bit O of 1+X3, and set all bits O of the remaining addresses to "0".Meanwhile, set "al" to RAM address l + Set all n to "On."

RA is synchronized with a constant clock using HSYNC as a reference.
When reading the data of M sequentially,
For example, as shown in FIG. 13(C), addresses X and X3
The data "B" is read out at the point J- of FIG. 13(d) 86-0 to 86-n.

Since it is connected to both K terminals, the output is a toggle operation, that is, when '1' is read from RAM and CLK is input, the output changes from '0' to 'l' and from 'l' to '0'. do,
Interval signals such as AREAO, and therefore area signals, are generated. Furthermore, if the data is set to "0" over all addresses, 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. Interval occurrence alternately and C

The gate 88B is opened and the gate 88B is closed to read out from the RAM 35A, and the total bit width and n bits are input to the flip-flops 86-0 to 86-n to J-, and the section signals AREAO to AREAn are generated according to the set value. is generated.

During this time, writing from the CPU to B is via address bus A-
Bus, data bus D-Bus, and access signal R
/W is used. Conversely, when generating a section signal based on data set in RAM885B (C31041
By setting C5) = (1+ Or 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.
Area switching signal ECH591 output from port 25
is selected by the selector 89, and the AND gate 9

If 0 is formed, the image is cut out from X to

It will be easily understood that the image is cut out in the section up to.

FIGS. 14 and 15 show the configuration and control timing of the area restriction mask bitmap memory 91. As can be understood from FIG. 2, for example, by using the detection output 592 of the color conversion circuit, which will be described later, it is possible to create an area restriction mask that limits the area only to a specific color area in the document.

It can be configured with 2 chips.

The signals 592 and 593 input to the selector 93 in FIG. 14(a) are data input lines for mask generation, as described above, and are connected to the binarization circuit of FIG. 2 by the switching line 594. When output 593 of 92 is selected,
First, in order to count the number of “bi” in a 4×4 block,
Buffers 94A, 94B, 94 for 1 bit x 4 lines
C, 94D. FIFO94A to 94D are
As shown in the figure, the output of 94A is connected to the input of 94B, the output of 94B is connected to the input of 94C, and so on, and each FIF
The output of O is sent to latches 95A to 95C in 4 bits in parallel, and
It is latched by CLK (see the timing chart in FIG. 14(d)).

FIFO output 595A and latch 95A, 95

Each output 595B, 595C, 595D of 95C is added by adder 96A, 96B, 96C (signal 596),
In the comparator 97, the CPU 22 compares the value with the value set via the I10 port 25 (for example, "12"). That is, here, it is determined whether the number of 1's in the 4×4 block is greater than a predetermined number.

In FIG. 14(d), the number of 1's in block N is "14" and the number of 1's in block (N+1) is "4", so the output of comparator 97 in FIG. 14(a) 59
7 is 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. 100H is an H address counter that generates an address in the main scanning direction of the mask memory, and since one address is assigned to a 4×4 block, the pixel clock VCLK is divided by the frequency divider 101.
Counting up is performed using a clock frequency divided by 4 by H.

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.
The operation of the H address and ■address is controlled to be synchronized with the counting (addition) operation of the "B" in the 4x4 block. Output, 599
．． 600 is NOR'd by a NOR gate 102, and a signal 602 for gating the clock 601 with frequency divided by 4 is connected.
As shown in FIG. 4(C), a 4×4 block should be latched only once (the latch signal 598 and 603 are data buses included in the CPU bus 508 (FIG. 2)). , 604 is an address bus as well;
A signal 605 is a write pulse WR from the CPU 22. During a WR (write) operation from the CPU 22 to the memory 99, the write pulse becomes "Lo" and the gate 104.
105. 106 is 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 the H address counter,
■When performing sequential WR (write) and RD read using the address counter, gates 107 and 108 are opened by the control lines of gates 107 and 108 connected to the I10 port 25, and sequential addresses are supplied to the memory 99. Ru.

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 in units of 4 pixels, the interpolation circuit 109 in Fig. 2 smooths out the jagged portion to give 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, the FF is inputted to GND, that is, 00H, to the B input, and either one is switched by the output 606 of the bit map mask memory mentioned above. As a result, the interpolation circuit 111 outputs FFH within the area mask and OOH within the area mask. This is as shown in (i) of FIG. 17(b). The interpolation circuit 111 uses, for example, the 1-fire interpolation method, the high-order interpolation method, and the 5-inch interpolation method.
Any circuit may be used, such as an interpolation method (and a well-known circuit configuration may be used. Since the output of the interpolation circuit is multi-valued, it is binarized by the binarization circuit 112. As shown in (ii) of FIG. 17(b),
The original boundary A is changed to B to ensure smoothness of the boundary.The selector 113 either outputs the output of the mask memory as is (selects A), or smooths it after interpolation as described above. The selection signal 608 connected to the I10 port of the CPU 22 switches as necessary whether to select and output a mask signal having a boundary.
Furthermore, select the output of the region restriction mask with the selector 89 in FIG. When the output of the mask memory of the map 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, the result is as shown in FIG. 18(b).

Reference numeral 116 in FIG. 2 is a density conversion circuit, for example, as shown in FIG. As shown in Figure 20 (F
Consists of IFO. 609 is H shown in the same figure (b)
3YNC, Lo pulse is input once for each line as a line synchronization signal, and WR (write) inside the FIFO
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.
By inputting 16, →l→2→3→4→1
→ 2 → 3 → l → 2 → 3″ reading is performed repeatedly. In other words, Repeat
By applying the signal 616 to the FIFO, it is possible to repeat the same image as shown in FIG. 4(c). Therefore, write data <"1" as shown in FIG.
A dotted line (cut line) is formed by combining in the synthesis circuit 115 in FIG. 1 at the time of reading.

As mentioned above, the image is
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 data “1”, the tangent line becomes (
By writing as in C), it becomes possible to form black frames on the image. The image signal 612 output from the repetition circuit 118 is input to the image synthesis circuit 115 and various image processing is performed thereon.

<Synthesis> Next, the details of the synthesis circuit will be explained using FIG. 25 (A-1), 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. 1 (A-1). That is, each code number (hereinafter referred to as an area code) obtained from the area code generator 130 is processed, although the details will be described later.

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 R shown in FIG.
Parameters corresponding to the editing process are set in AMs 135 and 136 and registers 140 to 142.

Further, in FIG. 25 (A-1), 132 is a selector that selects the output of either the area code generation circuit 130 or the register 131. In addition, 130 is the synchronization signal H3YN
An area code generator that automatically generates an area code according to C and CLK, register 131 is connected to CPU bus 5.
This is a register into which the signal from 08 is input. 135,1
36 is R in which an area code and processing or image data corresponding to the area code are stored as a table.
It is AM. As shown in FIG. 25(F), the contents of the tables in the RAMs 135 and 136 include a code inputted as an input address through the selector 132, and codes C0, C0, and C0, which indicate the formed color when the printer is forming images sequentially. C1 is given, and its output has a 3-bit function code and 8-bit data. 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 the decoder outputs SO, Sl, S2°S3. This is a selector whose selection state changes according to S4, and 144 is selector 1.
43. This is a multiplier that multiplies the outputs of 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 a signal "l" at the end of each area of the image), and the signal 613 . This is a decoder that decodes three characters: a character signal indicated by 614 and a function code inputted via the selector 137.

Next, the above-mentioned area code will be explained. For example, as shown in Figure 25 (B), the area code is
When areas 148 are specified using the digitizer 16 or the like, a number, ie, an area code, is assigned to each area to distinguish each area. In this embodiment, the entire area of the document is assigned the area code "0" as shown in FIG. 25(B).
For example, a rectangular area with diagonal lines at points a and b is set as area code "1," 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 sections CD and E-F.

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-1) 130.

This generation 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. 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
25, it is connected to the CPU. 149 generates a RAM address by counting Video CLK with an address counter. Further, the counter 149 is reset by HSYNC, and the same address is sent to the selector 151 every time a new line is scanned.
．． 152 to the RAM 153. Give to 154.

Therefore, in response to the reset, the RAMs 153 and 154 read data from the start.

An interrupt generator 155 generates an interrupt signal INT to the CPU and toggles the flip-flop 158 at J- when it counts HSYNC which is input by the pre-programmed number from the CPU by the CPU data bus 625 and chip select 624. The RAM read out by the address counter 149 is also switched by the operation. 151. 152°156 is a selector which selects A, according to the output of the flip-flop 158.
By selecting one of the B inputs, the RAM 153,
154 is selected.

FIG. 25(D) is an explanatory diagram showing the data structure of the RAMs 153 and 154. MS 81 b i as shown
It is divided into t and the lower 6 bits, and the MSB represents the change point between the specified area and the unspecified area as described above,
The lower 6 bits store a changing area code.

The address of the RAM corresponds to the Y coordinate which is the main scanning direction. For example, FIG. 25(D) shows a designated area 159 (area code "20") on the document 150 shown in FIG. 25(E).
This shows the RAM data when scanning between A-8. At this time, the entire area of the original is given an area code "O'". Area code set in reverse is “20”
This is an example when . Set the RAM with the above settings to the 25th
(C) The RAMs 153 and 154 are read out sequentially from the address generated from the address counter 149 to generate an area code. For example, when scanning the section shown in FIG.
” (area code “O”) is read out, and as shown in Fig. 25 (C
), the lower 6 bits are latched by the latch 157 using the MSB 627 as a latch signal, and the area code "0" is output. Also, when the point a(0,P) is reached, the output of the RAM is the MSB, and the lower 6 bits are
20'' is read out, latched in the same way as above, and area code ``20'' is output.The address advances further and the next MS
Area code "2o" is output until B becomes "l". In other words, the address r is read and the area code is "20" until the data is newly latched as described above.
' continues to be output from the latch 157.

The scanning further progresses, and when the main scanning in the Y direction is completed, it advances by one in the X direction and HSYNC is counted by the interrupt generator 155. At this time, the address counter 149 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, one of RAMs 153 and 154, continues to be read until the scanning of section C-D including point b in FIG. If the count number of H3YNC in the X direction, in this example, (qo) is set in the device 155, the interval A
When the scanning from -B to section C-D is completed, the interrupt generator 155 generates an interrupt signal INT, and at the same time, the interrupt signal INT is read out by the selector 156 by the toggle operation of the flip-flop 158 in FIG. R.A.
M is switched. As a result, the next area information programmed in advance is output from the RAM selected by the selector 156. Further, when the interrupt INT occurs, the CPU uses the coordinates and area code of the area obtained by the above-mentioned means to send a new and different data to the interrupt generator 155 and also to the idle RAM, that is, the RAM that has not been selected by the selector 156. Set the signal according to the specified area. This setting is performed under the control of the data bus 625 and chip select signals C2 and C3 from the CPU. The area code 626 can be generated for the entire screen of the document with a small memory capacity by using the above-mentioned configuration, that is, by sequentially switching between the two RAMs and programming the idle RAM by the CPU.

As mentioned above, the area code 626 output from the area code generation circuit 130 shown in FIG. 25 (A-1) is input to the selector 132 together with the image signal, and editing processing is performed for each area based on the area code. ing.

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. Due to such a configuration, 131. 132 are provided.

131 shown in Figure 25 (A-1) is a register and the CPU
It is connected to 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, MSB621 1 bit is input to decoder 146 and selector 137, other signals are input to RAM 13
5.136 is input in parallel.

The RAMs 135 and 136 are connected to the CPU bus (data bus 62
5. CP by 508 (generally refers to address bus 627)
It is connected to U and has a programmable configuration.

FIG. 25(F) shows the data structure of the RAMs 135 and 136. 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 62 are input as address inputs.
9. 2 bits, 'total 6 bits are input.

At this time, by setting the color select signal C6r CI+ C2 to 2 bits CO and C1 from the LSB, it is possible to select which of the four colors the image signal is sent in frame sequential manner, and access the area code and color by color. I am changing the address.

In this embodiment, as will be described later, M (magenta), C (cyan), and Y (yellow) are used for each color removed when forming an image with the printer 2.
, Bk (black) images are transferred in sequential order. At this time, the color selection 629 signal-tijc shown in FIG. 25(A) indicates the type of color to be transferred. +CI (Figure 10 (a
) is the same signal as C8 and C1 shown in ). 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 addition,
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 MSH 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 S1 from the selector 139.

The selected function code is input to the decoder 146 and output as a character signal 622, as well as an area code M S B b
Together with the i t 621, a control signal 623 for each editing process is generated. Each control signal is used as a selector selection signal and editing is performed by changing the signal flow. In this embodiment, the following six editing functions are realized using the control signals.

(2) In-area through designation Within the area, the function outputs the image signal without performing any processing. The input image signal passes through a negative/positive inversion circuit (described later) shown at 138, is selectively outputted from the selector 143 by S2, and is inputted to the multiplier 144. On the other hand, one of the RAM data is selected from the selector 139 by Sl, and then S3. It passes through a selector 145 determined by S4, is operated on the image signal by a multiplier 144, and is output. At this time, the density of the image is determined from the RAM data input to the multiplier 144, and the density and color balance can be varied independently for each area by setting a different count for each color sent in frame sequence. .

That is, when the user sets the color balance of the area after setting the area using the operation panel, the CPU transfers the setting value to the RAM 135 or R via the bus 508.
Write to AM136. Furthermore, the B input of the selector 145 may be selected and multiplied by the image signal 612 by the multiplier 144.

■Intra-area masking This function outputs an image that is uniformly filled with any other color over the entire designated area.

For example, when scanning a certain area with this function set, S2
RAM data is selected instead of the image signal and input to the multiplier 144. On the other hand, the coefficient is the control signal S3.
Select the register 142 from S4, and although it is not shown in the figure, it is connected to the CPU by a bus and the CPU
A more suitable coefficient such as “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 143 selects the data in the RAM 135 or 13゛6, and when it is Low, the selector 143 selects the image signal.
The decoder 146 performs insertion by outputting o-34. In addition to the above character signal, 33. S4 also changes, and the coefficient of the multiplier 144 is set so that the character signal 622 is High.
, register 140 is selected. As mentioned above, this is also connected to the CPU bus, and an appropriate coefficient is set in advance (normally, 1 is set in the register 140. In particular, by changing the coefficient set in the register 140, You can freely change the density of inserted characters.

■ Insertion of characters within an area (2) A function to mask the inside of a specified area with a specified color as shown in Figure 25 (H), and to insert characters in the same area with another specified color as described above. It is. While scanning within the designated area, the selector 143 is in the R position as described above.
AM data is selected. As mentioned earlier, at this time,
The selector 139 is switched based on the character signal obtained from the bitmap memory shown in FIG. 25(G). That is, if the data is not a character, the data in the RAM 135 is output, and if it is a character, the data in the RAM 136 is selected. Incidentally, in the RAM 136, for example, density data of characters within the region, and in 135, density data of, for example, characters other than the characters within the region are written in advance via the CPU bus 508.

Similarly to the above, coefficients as well as character signals are stored in the register 142. 140 is selectively output.

The multiplier 144 calculates and outputs the result.

That is, since the registers 140 and 142 are provided separately, the densities of the text area and the areas other than the literature area can be set independently.

(2) Negative/Positive Reversal within Area This is a function to invert only the negative/positive image within the area and output it, and this is performed by switching the negative/positive inverting circuit 138 using the control signal SO.

The output from 138 is output with the same settings as the through function.

■ Inserting negative/positive inverted characters within an area This is a combination of the above-mentioned intra-area character insertion function (1) and the above-mentioned intra-area negative/positive inversion, and is a function that inserts characters into negative/positive inverted images within an area. . The character insertion means is the same as the means described above, so a description thereof will be omitted.

In the embodiment described above, the operation of the decoder 146 in FIG. 125(A) is shown in FIG. 25(1).

1 to 6 shown in the leftmost column in the map reading correspond to the above ■ to ■
It shows each function. Further, the left side indicated as "input" in the figure is the input of the decoder 146, and the right side indicated as "output" is the output 5o-34 of the decoder 146.

For example, it may be a G signal or a signal obtained by taking a weighted average of R, G, and B at a predetermined ratio. FIFO40
The image data written to 50E-R is read out by control signal 9101E as explained in the previous section, and is read out by control signal 9101E.
The data is binarized by the binarization circuit shown in FIG. 1 and sequentially written into the memory. At this point, "l" white becomes "on".

The CPU writes a predetermined value to the register 4053 via the bus as the binarization threshold. For example, Fig. 27 (D-2
), a heart-shaped document A with a certain density on a white background is prepared, and an area B is designated as shown by the dotted line in the figure. By reading this area into the bitmap memory E, a binary image of "0" and "l" as shown in the figure is stored in the bitmap memory.

4080E is a counter for controlling the read/write address of the memory 4060ER, 9141E is a counter control for controlling the count state of the counter 4080E, and the system controller 4210
The read/write position is controlled by the CPU in the same way as explained in FIG. 29. By reading this data sequentially as shown by the arrow, the second
A non-rectangular area signal as shown in F in FIG. An 8-bit capacitor register 4074 connected to the CPU bus is provided at one input of the select'y 4071, and is configured to preset a predetermined output density value, for example, 80H is input. Therefore, when the signal 4072 is "BI", the selector outputs the set density value to 4172, and as a result, the set density value is output to the heart-shaped area in the figure.

Further, the most significant bit (MSB) of 4172 is output to 4173 (referred to as BI multiplication signal) and used as a non-rectangular area signal.

Also, the above-mentioned 4171.4172 is (2) in Figure 27 (B).
B) is output to the second part via the selector 4230.
It is input to the video interface 201 shown in the figure.

In the bit map E shown in FIG. 27, the density set by the register 4074 shown in FIG. 27 (D-1) is rewritten via the CPU for the binary image stored in the memory 4060E-R as its output. It can be set arbitrarily. In addition, “
If data of 80H'' or more is written, a bit image is output to the signal line 4173.

<Image storage from the SV recording/playback device 31> The system of this embodiment stores video images from the SV recording/playback device 31 in the image storage device 3 as shown in FIG. It is also possible to output. The image processing device 3 also handles input images.

In the following, a description will be given of how a video image from the Sv recording/reproducing device 31 is taken into the image storage device 3.

First, regarding the control of capturing video images from the SV recording/playback device 31 into the image storage device 3, FIG. 27 (A-1),
This will be explained below with reference to block diagrams of the image storage device 3 shown in (A-2) and (B).

Figure 27 (A-2) shows the analog interface 453
FIG. 2 is a diagram for explaining the internal configuration of 0.

The video image from the Sv recording/playback device 31 is input as an NTSC composite signal 9000 type through the video input terminal 4500, and is converted into separate R, G by the decoder 14000.
, B signal, and a composite 5YNC signal, which are four signals, 9015R, G, B, and S.

The decoder 4000 also decodes the Y (luminance)/C (chroma) signal 9010 from the video input terminal 451° in the same manner as described above. 9020R to selector 4010.

The input signal is in the form of an NC signal.

The selector 4010 is connected to the CPU bus 9610, and selection of the signals 9030RP-S and 9020RNS 17) can be made programmably from the CPU.

The sampling clock can be selected using the PU4360.

Further, the composite 5YNC signal 9050S selected by the selector 4010 is transmitted to the TBC/HV separation circuit 40.
30 and the TBC/HV separation circuit 40304,
: From the composite 5YNC signal 9050S, a clock signal 9060C, a horizontal synchronization signal 9060H, a vertical synchronization signal 9060V, and an image enable signal 9060EN shown in FIG.
50 is entered. -The enable signal EN is a signal indicating a certain image area.

As described above, the selector 4250 is a selector that selects and outputs images from the color reader 1, images from various video devices (temporarily assumed to be an Sv player in this embodiment), and images from the film scanner 34 as the image source. . The specific operation will be explained using FIGS. 28(B) and 28(C).

For example, when selecting an image on the video equipment side, the control signal 5

051S is 9420R, G, B, 94 respectively
Combined with 20S.

The same applies when inputting image data from other devices. Furthermore, this embodiment is characterized in that a tri-slat buffer is used in the selector 4250 to use a bidirectional communication line for connection with the color reader 11 or film scanner 34.

Among the 9051 output from the TBC/HV separation circuit 4030 of this embodiment, for example, in the case of NTSC standard, TVCL
The K9060C signal is a clock number 8 of 12 and 27 MHz, the 9060B signal has a pulse width of 63.5 μs at m, and the 9060V signal at fT mouth tube 1 has a pulse width of 16.7
m S signal.

Selector 42 is configured so that such a video image signal is input.
50, the CPU switches each switch 4254R, G, and B of the filter 9500 to the upper side in FIG. 28(A). Therefore, the data is input to any of the memories A, B, C, D, E, and M without being filtered. In addition, when importing images from the reader, there are images that may cause moiré, such as images with halftone dots, so each of the above-mentioned switches
254R, G, and B are switched downward to prevent the occurrence of moiré. Next, the explanation will be given again using FIG. 27(C).

FIFO memory 4050AR, 4050AG, 4050
AB is completely reset by the TVH8YNC9060H signal, and data 9060R, 9060G, and 9060B are written from address "0" in synchronization with the TVCLK9060C signal. This FIFO memory 4050AR, 4050
A.G.

4050AB is written by the system controller 42.
This is performed when the WT signal 9100 output from 10 is activated.

This FIFO memory 4050 by this ■ signal 9100
Details of write control of AR, 4050AG, and 4050AB will be explained below.

For example, if the Sv recording/playback device 31 in this embodiment conforms to the NTSC standard, the pixel capacity of the digitized video image from the Sv recording/playback device 31 is 640 pixels (H) x 480,480 pixels.
This is the screen capacity in pixels. Therefore, the CPU 4360 of the image storage device 3 first writes setting values to the comparators 4232 and 4233 so that the number of pixels is 640 in the main scanning direction.

Next, set the input of the selector 4213 to the CPU bus 9610 side, and store "480 pixels in the sub-scanning direction" in this RAM 4213.
Write 0”.

Furthermore, 100% data is set in the rate multiplier 4234 that sets the magnification in the main scanning direction.

The image information of the Sv recording/playback device 31 is stored in the memory 4060AR.

When storing data in AG and AB, the system controller 42
10 is outputted from the TBC/HV separation circuit 4030 at 9060V at the current level and 9060H at the level M.

TVCLK9060C is ffl 945 shown in Figure 29.

Connected to H9452 and cLKxN9456.

As described above, by sending the image control signal to the Sv recording/player interface side, the A/D converter 402
1 of the video images of 9051R, 9051G, 9051B which are output signals from OR, 4020G, 4020B
Main scanning data is input to a filter circuit 9500,
The output signals 9420R, G, B are the FIFO memory 4
It is stored at the same size in 050AR, 4050AG, and 4050AB.

The memory capacity of this embodiment is, for example, 640 pixels (640 pixels) of the aforementioned NTSC standard video still image per memory A.
1) x480,480 pixels), and when stored at the same size in memories A to D, a total of 16 types of images can be stored.

These memories A, B, C, and D can be easily attached to and removed from the main body of the device and can be expanded.
80 pixels) video images can be stored as well. Details will be explained below.

In this device, when the power is turned on, the CPU 4360 starts a program that detects the capacity of each memory, and the CPU 4360 detects the capacity of each memory.
The result is stored in the work register in 0. 32nd
Figures (B) and (C) are explanatory diagrams illustrating the algorithm of the above-mentioned program.

For example, for the sake of simplicity, if 406OA-R in memory A is represented in a schematic diagram in association with addresses as shown in the figure, the shaded area is the expanded area, and if no memory is installed at the corresponding address aH, data cannot be stored even if the CPU 4360 accesses it.

On the other hand, after adding memory in the area corresponding to the shaded area,
The memory capacity per image increases and becomes compatible with high band specifications, and a memory cell also exists at the address aH, making it possible for the CPU 4360 to access data.

Here, the CPU 4360 writes b bytes of predetermined data from a fixed address aH, then reads the data from address aH, and detects the capacity of the memory by comparing it with the written data.

FIG. 32(C) shows a flowchart of such operation.

That is, when the memory is not expanded, the terminal at address aH is open, so when the CPO 4360 reads data, a high level continues to be output, so the capacity of the memory can be detected by the above-described operation. The result of detecting the memory capacity is stored in the work register of the CPU 4360 as described above, and the 27th
As shown in figure (A-1), 08C4031 is connected to CPU436
A/D conversion 4020R, G, B by controlling
The sampling clock is changed, and the sampling clock is switched between high-band input and low-band input depending on the memory capacity.

Furthermore, in this embodiment, the Sv control connector 442
0 and the Sv player (player) 31, the Sv player 31 is connected via the Sv controller 4420.
Commands can be exchanged between the CPU 4360 and the CPU 4360. At this time, the Sv player (player) detects whether the video image being played back is an image recorded in high band mode or an image recorded in low band mode. Since such detection means are well known, they will not be specifically described. Next, the Sv player sends the corresponding command to the CPU 4360 via the Sv controller 4420.
The sampling clock 60 can be controlled from the data regarding the remaining capacity of the image memory stored in the work register and the command, thereby enabling more precise correspondence. For example, when the memory supports high band and the video is high band, the sampling clock becomes high band. Also, if the memory supports low band or the video equipment supports low band, the sampling clock will support low band.

In addition, the CPU 43
60, the gains of the video amplifiers 4011R, G, and B are optimally adjusted and stored in the memory again, so that the best image can be stored (hereinafter referred to as AGC (auto gain control)). The details will be explained below. FIG. 32(D) shows an algorithm flowchart. The operation is performed by pressing the AGC key in diagram H in FIG. 47 or diagram 0 in FIG. 50(A).

When storing video images, first of all, for example, the amplifier 4011R, which can control the gain in eight steps.

Set G and B to the minimum gain (Sl). After setting, the video image is stored in memory (S2), and the CPU
The following check is performed (S3). The check in S3 is performed when the image data is, for example, 8 bits.
The data of the stored image is the maximum value FF) I (in this example,
Check whether the brightness is set to the maximum brightness value. This checks the entire image area or a certain part of the image area.

In this embodiment, a partial area in the center of the stored image is used as a representative of the entire area. This can shorten the checking time.

These checks are performed for each of R, G, and B of the stored image. In S4, if any value among R, G, and H is 8-bit image data, check whether it is FFH. If there is no FFH pixel, raise the gain of amplifier 4011R, G, and B by one step and try again. Store it in the memory and repeat the processing from S2. If FFH is not found, the process ends.

By performing the above processing, images can always be stored at the same level even if the recording level (brightness) differs between various video devices.

The AGC described above is performed via the CPU 4360, but the A/D converter 4C32 shown in FIG. 27 (A-1)
This is also possible by adding a comparator to the outputs of OR, G, and H, and changing the amplifier gains of the video amplifiers 4011R, G, and B based on the output.

In addition, by activating the AGC function, gain control of the input video signal and R, G
, the color balance of the B signal is also automatically corrected.

The color balance function will be explained in detail later.

(Image storage from the Sv recording/playback device 31 during SV indexing) During the Sv indexing, 25 images from the Sv recording/playback device 31 are stored in the memory.

SV image information 9421R, G, B from the analog I/F 4530 in FIG. 27(A) is stored on one memory board of memories A to D on 25 pages with 320 x 240 pixels as one image unit during indexing. Memorize minutes.

Image storage at the time of such Sv index is based on the normal image size of 640 x 480 pixels from the video equipment.
/2 and stored in memory at 320 x 240 pixels. By setting the size of 320 x 240 pixels to one pixel, 25 screens can be stored on one memory board having 2M pixels.

This situation is shown in FIG. 33(b). Image 1 ~ Image 2
Image signals for 25 screens up to 5 are stored in a 2M pixel memory.

The image information of 640 x 480 pixels from the SV recording/reproducing device 31 is halved and 320 x 240 pixels is stored in the memory as one image of information.

The reduction of the 87 image information is omitted because it is performed by FIFO writing/reading control in the same way as the image storage from the color reader 1 described above.

After storing one screen of image information from the Sv recording/reproducing device 31, the CPU in the image storage device 31 (Fig. 27 (B) +7
) 4360) is the SV controller 4400
A track up signal is sent to the recording/reproducing device 31.

Based on this signal, the Sv recording/reproducing device 31 moves the track accessed by the reproducing head toward the inner circumference side by one track with respect to the Sv jacket. Next, the image signal recorded on the track being accessed is reproduced and sent to the image storage device 3. The image storage device 3 moves the head by one track again in the same manner as described above, and stores the image signal recorded on the next track in the memory.

By repeating this operation, image signals of 25 screens are stored in the memory.

<Image display from the Sv playback device 31 at the time of Sv indexing> Image information from the Sv playback device 31 at the time of Sv indexing is sent to the Sv playback device by sequentially changing the tracks that the playback head is accessing for the Sv jacket, specific is displayed on the monitor television 32 while being tracked up. This display is shown in FIG. 33(C).

87 image information 9421R, G, B from analog I/F 4350 in FIG. 27(A) is memory M1.128
x96 pixels are stored as one unit for 25 screens.

The monitor display in Sv index is 11 times the size of the normal image from the video equipment is 640 x 480 pixels.
5 and store it in memory as 128x96 pixels.

The reduction of the 87 image information is performed by controlling the writing and reading of the FIFO memory, etc., in the same way as the image storage from the color reader I described above.

After storing one screen of image information from the SV playback device 31 in the memory M, the CPU ((7) 4360 in FIG. 27(B)) in the image storage device 31 executes the SV controller 0-4400.
A track-up signal is sent to the SV recording/reproducing device 31 via the SV recording/reproducing device 31.

Based on this signal, the Sv recording/reproducing device 31 changes the access position of the reproducing head for the sV jacket track-up, and sends the next track image to the image storage device.

The image storage device 3 stores the next image in the memory M in the same way as described above.
to be memorized.

By repeating this operation, images of 25 screens are stored in the memory M.

The image information stored in the memory M is stored in the LUT (Figure 27 (
Pass through 442OR, G of E), and D/A converter 4 of B).
430R, G, and B, and the index image is displayed on the monitor television 32.

Read Processing 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 unit 2° shown in FIG. 23 mentioned above.

For example, when a desired area for image formation is specified using a digitizer as shown in FIG. 37, the color reader l sends its position coordinates to the CPU 4360 of the image storage device 3 via a control line 9460 connected to a connector 4550. Such position coordinates are output as 8-bit 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. 12(d)) in the system controller 421O shown in FIG. 27(F). to obtain the desired image output.Specifically, R shown in FIG. 12(d)
Data corresponding to the coordinate information is set in AM555,556. FIG. 27(F) shows each signal output from the area signal generator. 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 1 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 when sending images from the image storage device 3 to the color reader 1 are 5ELECTC, 5EL.
ECT-E and '5ELECT-F are set to '0' to open the gates and set all other tri-slurt buffers to high impedance.Furthermore, 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, CLK, and 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 forming process 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 from the above-mentioned color 9-D, film scanner 34, or Sv recording/reproducing machine to the image storage device 3, thereby causing the image memories 4060AR and 4060AG to be described later.

4060AB stores a total of 16 image data, "image 0" to "image 15", respectively, as shown in FIG. 33(A), for example.

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, for example, the image forming position is set as shown in FIG. 34(A).

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. In the image storage device 3, this ITOP
Image forming processing is started by signal 551. Each image sent to the image storage device 3 is sent to the system controller 4 shown in FIGS. 27(A) and 27(B) in the image storage device 3.
Under the control of 210, the image is read out from the memory ABCD or the like.

A control signal 9102- output from the area signal generator (FIG. 27(F)) in the system controller 4210
0 to 3 should be the counter enable signal (for example, when reading from memory A, the counter control 914
It is input to 1A. Counter control 9141A enables the counter based on the input control signal, and selector 4070A's select signal 91
Controls 40A.

At this time, the counter control 9141A simultaneously outputs the first enable signal 9103A, and this signal becomes the write enable signal for the next-stage FIFOs 4140-0 to 4140-3.

With this access, each memory 4060AR, 4060A
G.

The image data stored in 4060AB is read out, and read image signals 9160AR and 9160A from each memory are read out.
G.

9160AB is a lookup table (LUT) shown in FIG. 27(C) 4110AR, 4110AG, 4
110AB, where logarithmic transformation is performed to match the relative luminous efficiency characteristics of the human eye. At this time, 4111
A is a signal for LUT selection and is sent from the area signal generator 4210, allowing arbitrary LUT selection for each area. In this embodiment, 16 types of LUTs can be selected. Converted data 9200AR from each LUT.

9200AG and 9200AB are masking/black extraction/
It is input to the UCR circuit 4120A. This masking/black extraction/UCR circuit 4120A performs color correction of the color image signal of the image storage device 3, and also performs UCR/black extraction during black recording.

Then, the image signal 9210 from these continuously connected masking/black extraction/UCR circuits 4120A 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, each image that was arranged sequentially as shown in FIG.
Parallel processing is possible due to the effect of 3.

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

9240-0 to 3 in Figure 27 (B) are FIFO4140
A reset write signal for −0 to 3 resets the FIFO address before writing. Also 93
20-0 to 3 are enable signals for the expansion interpolation circuit;
9340 selects an enlarged interpolation circuit to be used with the select signal of selector 4190. 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. In addition, in this example, the one-fire-tub method is used. 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 signals 93 and 30 converted into serial image data by the selector 4190 are subjected to edge enhancement,
And smoothing processing is performed. The signal then passes through LUT 4200 and is input to selector 4230 via signal line 9380.

The data (UB) 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 I together with the video enable signal generated from the area signal generator shown in FIG. 27(F) and the clock.

After the formation of all the image data for "Image O" to "Image 3" is completed, the next steps are "Image 4" to "Image 7", "Image 8" to "Image 11J", "Image 12J" to "Image 15J". Images are formed sequentially in the order of ``Image O'' shown in FIG. 34(A).
16 images of "Image 15" are formed.

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

Furthermore, in the case of images from the Sv recording/reproducing device 31, images on the Sv floppy can be continuously printed out, and also have a function as an index print.

When printing this Sv index, there are many cases where the color balance is taken differently depending on the model of the Sv player, and there are differences in the environment when the Sv left camera is in the shadow, that is, differences in color temperature. In order to do this, this embodiment has a function that automatically performs color balance.This color balance function is
Figure H in Figure 47 or AG in Figure 6 in Figure 50(a)
It works by pressing the C key. Details will be explained below.

N pixels (1≦N≦total number of pixels), in this example, a total of 256 pixels, are processed by the CPU 4360 from the image data of multiple screens stored in the memory, and based on the processing results. Although not shown, the CPU 4360 selects or creates an optimal correction table from the ROM in the CPU 4360 and creates the lookup table 4.
Set to 110A-R, G, B. For example, when selecting and setting, one of the curves ■ to ■ in FIG.
Select and set one from ■ to ■ in Figure 35 (C).

As will be described later, this also allows correction of the monitor display image.

Next, a method for selecting a correction table using image data in memory will be described.

Next, selection of a correction table will be explained.

FIG. 35(D) is a diagram for determining the inclination of the correction table in FIG. 35(C), and FIG. 35(E) is a flowchart for determining the inclination of the correction table.

First, the CPU 7 sequentially takes in N pieces of image data in the memory 3 (step SL) and calculates R, G, and B signal values Ri, Gi, and Bi (1 for the i-th pixel data).
≦i≦N), the signal value is not saturated (for example, when the image data is 8 bits, if pure white is 255 and black is 0, not saturated means it is not 255) pixel data Take out. This is Ri, Gi.

This is because if even one of Bi is saturated, the data deviates from the color balance of the original data, making it impossible to accurately determine the color balance.

Further, the sequential loading of N pieces of image data in the memory 3 is performed, for example, as follows. That is, when data for a plurality of screens, for example 20 screens, is captured in the memory, color image data is sequentially sampled from each of the 20 screens. In other words, in this embodiment, by averaging data sampling from a plurality of screens in the memory 3, even if there is a screen whose hue is uneven among the plurality of screens, the overall data is not affected by the uneven hue of the screen. The average color balance correction can be performed.

Among the captured signal values, the R9G and B components of the pixel with the largest minimum value among N pixels are set as RMAX, GMAX, and BMAX (step S
2). The minimum value among Ri, Gi, and Bi represents the characteristics of the pixel data. That is, for reddish pixels, Ri,
The minimum value of Gi and Bi is R4.

The pixel with the largest minimum value among Ri, Gi, and Bi is the pixel with the weakest component representing the characteristics of the pixel data. Therefore, RMAX, GMAX, BMAX are 8
7 The Ri, Gi, and Bi acid components of the pixels representing white in the image can be considered. The maximum value of RMAX, GMAX, and BMAX is set as DMAX, and the difference between the maximum value and the minimum value is set as DSA (step S3). DMAX is the faintest component among the R, G, and B components of a pixel considered to be white. DSA
If =O, it means that the color balance (white balance) of pixels that are considered to be white is correct, but DSA≠0
If not, correction is required so that DSA=O.

Next, average values AVER, AVEG, and AVEB of Ri, Gi, and Bi of the N pieces of image data are determined.

Then, set the maximum value of AVER, AVEG, AVEB (7) to AVEMAX.

The difference between the maximum value and the minimum value is set as AVESA (step S4
). AVEMAX is average pixel data (7) R,G.

It is the thinnest component among the B components. If AVESA=0, the average density of the 87 images is achromatic, indicating that the color balance is maintained to some extent. This is an application of Evans' theorem, which is used when printing transparent films with silver halide, to 87 images. AVE
If SA=O, the color balance is out of order, so correction is required to set AVESA=O.

Maximum value DMAX of each component of white level, maximum value AVHMAX of each average value of Ri, Gi, Bi of all image data, chromaticity DSA of white level, chromatic color of average value of all image data The membership function for degree AVESA is 1-a shown in FIG. 35(D).

1-b, 1-c, and 1-d. Membership functions 1-a, 1-b, 1-c, and ld are each registered in advance in the ROM 13 as a table.

The CPU 7 calculates the grade of the white level dependence degree WDMAX of the brightness correction from the maximum value DMAX of the white level using 1-a (step S5). If the maximum value DMAX of the white level is large, it means that brightness correction is performed with more emphasis on the white level than on the average value of all image data. That is, a large DMAX means that the pixel determined to represent white is actually a pixel close to white. Conversely, a small DMAX means that a pixel determined to represent white is actually a pixel far from white. Therefore, it is not possible to emphasize the white level extracted from the N image data.

Next, according to step 1-b, the grade of the brightness correction degree WAVE is determined from the average maximum value AVEMAX (step S6).

This means that the smaller (or larger) the value of the average maximum value AVEMAX is than the center value, the smaller the degree of brightness correction. In other words, if the input image is originally dark, the correction to brighten the image If you do this, you will end up changing the characteristics of the input image more than necessary.

Therefore, in this embodiment, AVEMAX is
6, the brightness correction degree WAVE is gradually decreased. On the other hand, if the input image is originally bright, there is no need to make it any brighter, so AVEM
When AX is greater than or equal to D2, the brightness correction degree WAVE is gradually decreased.

Furthermore, the grade of the white level dependence WDSA of the color balance correction is determined from the chromaticity DSA of the white level using 1-c (step S7). If the chromaticity DSA value of the white level becomes large, there is a possibility that the intended white level is not white, so the data used for color balance correction focuses on the average value of all image data rather than the white level. It means to do.

Next, according to 1-d, the grade of the color balance correction degree WSA is determined from the chromaticity AVESA of the average value of all image data (step S8). Average chromaticity AVES
As the value of A becomes larger, there is a possibility that the image deviates from Evans' theorem, which means that the degree of color balance correction is reduced.

Furthermore, the CPU 7 calculates the proportion of color balance correction using the white level and the proportion of color balance correction using the average value, based on the white level dependence degree WDSA. Furthermore, the color balance correction ratio is determined by the sum of these values (step S9). In step S9, DMAX
/RMAX is based on the R component of the white level (it is a correction term,
AVEMAX/AVER is a correction term based on the R component of the average value. Then, for each dependence WDSA, (1-
BALR by adding the weights of WDSA)
seek. BALG.

The same applies to BALB.

However, the color balance ratio BALR, BALG, BAL
Since B needs to be some l, it is normalized (step 510). Furthermore, the color balance correction amount is determined from the color balance correction degree WSA (step 5ll).

On the other hand, in the case of brightness correction, the CPU 7 determines the brightness correction ratio using the white level and the brightness correction ratio using the average value from the white level dependence WDMAX of brightness correction, that is, the brightness correction ratio. Find AE. Furthermore, the brightness correction amount WAE is determined from the brightness correction degree WAVE. Here, DMAX representing the white level is set to 255, and the average value of all pixels is set to correspond to 127 (ie, 255/2). Then, the degree of dependence WDMAX is (1-WDMAX) on the amount of correction based on each of the white level and the average level.
The brightness correction amount WAE is calculated by applying the weight.

Then, the color balance and brightness correction amounts γ and γ are finally determined by the product of the brightness correction amount WAE and the color balance correction amount. , γ8 represents the slope in FIG.

The CPU 7 selects the closest slope from among (1) to (8) in FIG.

Set to B. Corresponding to (1) to (8), Fig. 35 (B
) is also selected, and the lookup table 411
Set to 0A-R, G, B.

In this way, the method of this embodiment calculates the average value and the R, G, which is considered to be the white level, from the R, G, and B image signals imported into the memory from the Sv left camera or floppy disk.

Find the B signal, and further calculate the average value and white level of R and G.

The grade is determined using a membership function prepared in advance from the characteristic value obtained from the B value, and the image brightness and color balance are corrected according to the grade. There may be discrepancies in color balance and recording levels due to differences in Sv camera manufacturers and models (
It is possible to correct differences in brightness. Furthermore, it has the effect of preventing excessive correction and preventing extreme corrections such as applying or not applying correction depending on a slight difference in the level of the input image. Therefore, there is an effect that the correction is performed more naturally.

By creating the LUT as described above and printing it out, a more faithful image can be reproduced (this process is referred to as color control).

The color balance function described above uses Evans' theorem to convert the input video signal from the initial color balance state (shown in FIG. 49E) into R, G.

It is to change the balance of B. For example, as a result of using the color balance function, redness (R) becomes stronger and blueness (B) becomes stronger.
), the color balance display changes as shown in FIG. 49F.

After operating this color balance function, if the user wishes to obtain a desired color tone, the color tone can be changed by pressing the color balance key shown in FIG. 49A. How to operate this color balance is as follows.
Omitted as it will be explained later.

In addition, in this embodiment, when adjusting the color balance, pixel data of multiple screens is sampled,
The color balance of the entire multiple screens stored in memory is automatically adjusted. Therefore, according to this embodiment, automatic adjustment of color balance can be realized with fewer malfunctions.

Film scanner 34 also uses an autochanger,
Index printing of film images is possible by automatically storing images one after another and printing on 24 or 36 sides.

<Image Formation by Layout at Any Position> The above explanation describes the control for developing and forming an image so that it can be automatically formed as shown in FIG. 34(A), but this embodiment The present invention is not limited to this example, and any image may be developed at any position to form an image.

Hereinafter, as an example of this case, "Image O" shown in FIG.

Then, operate the point pen 421 to detect the coordinates on 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 during image formation on the "l" line shown in FIG. 37, and FIG. 39 is a timing chart during image formation on the "12" line in FIG. 37.

The ITOP signal 551 is output from the printer 2 in the same manner as described above, and the system controller 4210 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 439o from 4060AG, 4060AB
Transfer images to. Next, after performing known image rotation processing in the work memory 4390 by the CPU 4360, the DMAC 4380j:yotte, the work memory 439
゜ to 4060AR, 4060AG, and 4060AB (8 images will be transferred 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 4210, which has received the development position information for each image, sends operation permission signals 9320-0 to 3 of the enlargement/interpolation circuits 4150-0 to 3 corresponding to each image, counter enable signals 9102-0 to 3, and LUTs.
Selection signals 4111A-D and each selector control signal are generated to obtain a desired image. At this time 8
When printing 7 images, the LUT is set according to the algorithm described above.

In the layout at any position in this example,
For example, counter O (4080-0) is assigned to image O, counter 1 (4080-1) is assigned to image 1, counter 2 (4080-0) is assigned to image 1, and counter 2 (4080-0) is assigned to image 1.
080-2) is image 2, counter 3 (4080-3
) operate corresponding to image 3.

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

Image memory 4060AR, 4060AG, 4060A
Reading “Image 0” from B is performed by counter O (408
0A-0), the data from address "0" to address "0.5M" (the storage area of "image O" shown in FIG. 36) is read out. This switching of the outputs of counters 4080A-0 to 4080A-3 is performed by selector 4070A under the control of counter controller 9141A.

Similarly, when reading “Image 1”, counter 1 (40

Denoted as 0AR, AG, AB.

The data of “Image O” and “Image 1” are stored in LUT411
It is sent to the masking/black extraction/UCR circuit 4120A via 0AR, 4110AG, and 4110AB, where it becomes a frame-sequential color signal 9210. This frame sequential color signal 921

Sent to 1. And system controller 4210
When the operation permission signal 9320-0.9320-1 from the enlargement/interpolation circuit 4150-0.4150-1 is enabled, the enlargement/interpolation circuit 4150-0.4150-1
is the FIFO read signal 9280-0. 9280-1
is enabled and read control is started.

FIFO memory 4140-0.4140-1 receives this signal 9280-0. 9280-1 starts transferring image data to the enlargement/interpolation circuit 4150-0.4150-1. The enlargement/interpolation circuits 4150-0 and 4150-1 first perform layout and interpolation calculations according to the area designated by the digitizer 16.

This timing is 9300-0゜9300- in Fig. 38.
Shown in 1.

The “Image 0” and “Image 1” data that have been subjected to layout and interpolation calculations are selected by the selector 4190 and then passed through the edge filter circuit 4180 and sent to the LUT 420.
It is input to 0. The subsequent processing up to the connector 4550 is the same as described above, so the explanation will be omitted.

Next, referring to FIG. 39, “12” shown in FIG. 37(D)
Explain line timing.

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

However, in the “12 line,” “Image 1” and “Image 2” are output, so the 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 line 12, image 1
and “Image 2” 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 934o 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 section 20, the printer 2 starts operating and starts conveying the recording paper. Then, when the recording paper reaches the leading edge of the image forming section, the IT
An OP signal 551 is output. This ITOP 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 the 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, the image transferred to the image storage memory as shown in FIG. 43 is shown in FIG. 27(C).
If the memory area is read out by the counter O (4080A-0) shown in FIG.
It is printed out in the area of image 0 in A).

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.

FIG. 37(F) is the counter 040 shown in FIG. 27(C).
80A-0 is a diagram schematically representing an image stored in a memory area read out by the 80A-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 O.

In the figure, the division sizes are a in the H direction and b in the V direction. These are used to calculate the first 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 TTOP signal 551 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 composition using bitmap memory E> Next, non-rectangular image composition 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 O that is desired to be output. Next, as in the previous section, the color reader 1 specifies and inputs the development area of each image using the digitizer 16. 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. The sent information is read by the CPU 4360 through the signal line 9460,
As already mentioned, 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). The data 301O can be programmably selected from 8-bit density data from the bitmap memory or the BI multiplied signal CPU by controlling the data set in this register using the register 1. 3020
．． 3030 is a gate for such selection. For example 8
When bit density data is selected, an OR gate 3040 synthesizes the image signal and the bitmap.

On the other hand, when the Bl signal is selected, the selector 3050 becomes a select signal, and the Bl signal can selectively output the image data having the density of the data set in the register 3050 and the image data 9380 from the memory.

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 is used as an I-select signal, thereby making it possible to synthesize non-rectangular images.

The Bl signal can be sent alone to the color reader 1, and the color reader 1 can process it using the BI multiplied signal.

That is, if the above-mentioned BI multiplied 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 1 in real time.
It is also possible to combine images.

That is, as described above, an image is read out 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. Since the processing of the color reader 1 is the same as described above, 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 when the reflection original read by the reader 1 is combined and the signal - from the image storage device lf3 are combined.

The image information of the color reader l read out in synchronization with the ITOP signal 551 is the output signal 5 of the black correction/white correction circuit.
59RGB, H3YNC at 11 in Figure 20
is output in sync with. Furthermore, only the area designated by the digitizer 16 is outputted from the four image information 205RGB from the image storage device 3. These two types of image information are input to the video interface 101, and an image of the color original is output from the composition circuit 115 except for the area specified by the digitizer 16, and the area specified by the digitizer 16 is input from the image storage device 3. Information is output.

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

Further, in this embodiment, as shown in FIG. 27 (D-1), the bitmap memory is connected to the CPU bus so that the CPU can develop a mask pattern 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 pattern.

With the above configuration, there is no need to create and read a mask button (you can easily create a mask button in the bitmap memory, and even more easily perform image composition as shown in Figure 37 (B). can do.

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 above-mentioned AND gate 3020 in FIG.
30 is inactive and the image data 9380 and the image on the bitmap memory are synthesized by the OR gate 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 patterns can be provided as CPU programs.

Furthermore, character data from the font ROM 4070 written in advance in the bitmap memory and image data are combined to create an image with a message written on the bottom of each image shown in FIG. 34, as shown in FIG. 37(E). is now available. 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 images and the contents of the image memory in the storage device to the monitor TV 32. It is also possible to output video images from the Sv recording/playback device 31.

On the other hand, the display controller 4440 outputs a 5YNC signal 9600 in synchronization with the output timing of these analog signals. This analog R signal 4590

By connecting the 5YNC signal 4590S to the monitor 4, the contents stored in the image storage device 3 can be displayed.

In addition, in this embodiment, the host computer 33 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 and 4410G based on the area information inputted by the host computer 33 under the same control as described above.

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 CPO 4360 shown in FIG.

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 new data is received from the GP-IB controller 4310 again, 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 A to C1, and monitor display memory M shown in FIGS. 27(A) and 27(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. In other words, input terminal 240L GP-IB controller 240

A DRAM controller 2405 (hereinafter referred to as DMAC) stores image storage memory 2406. are sequentially transferred to the display memory 2407 (for simplicity, R, G
, B are grouped together). The details will be explained below. Image storage memory 2406. display memory 2
407 is assigned an address as shown in FIG. 43, and an image is stored therein. In the figure, the lower address corresponds to the H direction, and the upper address corresponds to the V direction. For example, if point A is 100H in the H direction and 100H in the V direction, the address of point A is 100100H.

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 storage start address and the image size when reduced are set in the DRAM controllers 2408 and 2409. After completing the above settings, the DMA is executed by the CPU.
A command is sent to the C2405 and image transfer is started.

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 I
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 "σπ], -nΣW1 by DMAC,
Image data is written sequentially. At this time, the DRAM controllers 2408 and 2409 are IOW
The signals are counted and the write address is sequentially incremented from the set start 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 ① reversal, and therefore performs reduction by thinning out 1 reversal. For example, if the reduction is set to 3/4 as described above, the DMAC will thin out the reversal once every four times in the H direction, and in the ■ direction, it will be configured so that the section rσW of 4 lines and 1 line is not output. As a result, the reduction is performed by controlling the writing to the memory by 1.

FIG. 44 shows a timing chart. As shown in the figure, the read address is input to the work memory 24o4, 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 by the shoulder signal.

At this time, if the I signal is thinned out, 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 I.

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

In the color reader l, press the external device key (2) on the operation unit 2o.
0-2), the diagram A in FIG. 47 is displayed on the liquid crystal touch panel of the operation unit 20.

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

When you press the image registration key in Figure 47 A, the LCD touch panel changes to something like C, and the input source displayed in the area surrounded by the broken line indicated as X in Figure C! Select by pressing the key.

In this embodiment, there are three types of input sources: the color reader 1, the film scanner 34, and the Sv recording/reproducing device 31, and these are selected by operating the rice field 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 . Figures E, G, and H show input source selection (Qllfi) in Figure 0.
(selected by pressing the key). If you select a color reader, use figure E. If you select film scanner 34, use figure G.
In the figure, when the Sv recording/reproducing device 31 is selected, the diagram becomes H diagram.

When image registration of the color reader 1 is selected, the state shown in FIG. 47E is reached. In this state, the pointing pen 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 l. 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 key to display the G diagram, and then set the amount of memory to be used.

The length of the bar graph of the memory amount in FIG. G changes depending on the attachment of the memory ports (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 3, and also sets the amount of memory to be used when registering an image. The amount of registered memory to be used is determined using the country/date key, and by pressing the registration start key, the original scanning unit 11 shown in FIG. 1 scans 1 and reads 999 originals.

Image information from the document scanning unit 11 shown in FIG. 1 passes through a cable 501 and is processed by the video processing unit 12, and then output to the image storage device 3 via the video interface 201. 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 possible to input many images.

Next, 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 I, 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 and color control) 0N10FF will check whether the rotation direction is registered before registration starts.

and field/frame settings. After the above settings, by pressing the registration start key, the image storage device 3 imports the image information from the Sv recording/reproducing device 31 into the memory (Fig. 27 (C)). The method of storing images in the memory is as described above. It is omitted because it is the same as .

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 using the point pen 421 of the digitizer 16 shown in FIG. 23, and the memory contents of the image storage device 3 are printed out in that area.

The composition is performed using the point pen 4 of the digitizer 16 shown in FIG.
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 in figure B is selected, the display moves to the figure shown in figure F, and the number of the image to be formed in the set area is set using the numerical keys in FIG. 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 finished, the color reader's CPU
stores an image corresponding to the desired screen selected in FIG. F of the SV playback device in the storage device 3 depending on the type of external device selected in FIG. B, for example, in the case of SV.

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 pen 421 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) on the operation unit 20 shown in FIG. 1, the memory contents of the image storage device 3 are printed out in the areas 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 it is turned on, that is, when the image information in the image storage device 3 is printed out by the color printer 2, will be described.

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 country key, the bar graph moves to the left, which acts to amplify the red luminance signal electrically, so the red component displayed on the monitor becomes fainter. This is the lookup table (LUT) 4420R in the monitor memory in FIG. 27(E).

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

-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 LUT is rewritten 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(A) is a diagram showing an example of the display displayed when the r-OJ key is turned on in the state shown in FIG. 47A. Such a figure is shown in the display shown in B of FIG.
” is a diagram showing an example of the display when the key is turned on. That is, an operation for displaying the contents of the floppy disk reproduced by the Sv recording/reproducing device 31 on the monitor television 32 and an operation for printing out the contents from the color printer 2.

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

The Sv disk is capable of field recording on 50 sides and frame recording on 25 sides. The AGC key is an 0N10FF key for auto gain control and color control.

When the display start key shown in FIGS. 50A and 50D is pressed, the first 25 screens of the Sv disk are displayed on the monitor in the case of field recording, and when the display start key shown in FIG. E is pressed, the latter 25 screens are displayed. This situation is shown in Figure 33 (C
). In such a case, the CP in the image storage device 3
U puts the SV playback device into 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, the CPU in the image storage device 3 issues the following instructions to the Sv player. That is, 5 recorded on the Sv disk
The first 25 screens of the 0th screen are sequentially stored in the memory in 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 SV 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(A) are operations for printing out the contents of the above-mentioned index from the color printer 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 with S as described above.
Images for 25 screens are stored in the memory from the V recording/playback device 31. At this time, the image storage state in the memory is shown in Figure 33 (B
) is shown in ゛. After that, 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, the fixed pattern obtained by the operations shown in FIGS. 50(A), F, and G is printed out.

In the free layout, an image is read out from the Sv playback device from a pre-designated index Nα, and after being stored in the memory of the image storage device 3, the digitizer 1 shown in FIG.
The image is printed out in the area indicated by the pointing pen 421 of No. 6.

The synthesis is performed from a prespecified index Nα to S
After reading the image from the v player and storing it in the memory of the image storage device 3, both SV and SV images are placed in the area indicated by the pointing pen 421 of the digitizer 16 in FIG.
The image of the reflective original is combined with other areas and printed out.

If fixed layout is selected, B in Figure 50(B)
The number of print pages for fixed layout printing is set using the diagram. A for each image area in fixed layout
-P image area names are given, and each area (A-
FIG. 50 (B
) Glue and make settings using diagram E. For example, Figure 50 (
In figure B of B), if you select the 4th screen, the 5th
The display shown in Figure 0 of Figure 0 (B) is made. For example, if you select the area shown in A in Figure C, the display will then move to the diagram shown in D, and the index Nα of the 87 images to be formed in the set area will be displayed as shown in Figure 50 (B) and the numerical value in Figure B. Set using the key. By repeating this designation, a plurality of 87 images are designated as index fish.

Next, by pressing the start key on the operation unit 20, the 87 indexed images set above are loaded into the image storage device 3 and printed out in a predetermined area. This procedure will be explained using FIG. 50(C).

When the start key of the operation unit 20 on the color reader side is pressed, the color reader 1 issues a registration request to the image storage device 3.

The image storage device 3 instructs the Sv floppy track of the Sv playback device 31 to advance, that is, change the track being played back, so as to correspond to the specified index, and stores the image information corresponding to the index storm in the memory. Remember.

After registering all the images corresponding to the index Nα set by the operation unit 20, the image storage device 3 sends a registration completion message to the color reader l.

The color reader l sends the image print area of each index Nα, that is, layout information, to the image storage device 3, and also sends a start request signal.

The image storage device 3 sends the image information of Sv to the color reader 1 to a specified position in accordance with the synchronization signal from the color printer 2. After the color reader 1 processes the image information from the image storage device 3, it sends it to the color printer 2 to form an image.

The Sv free layout shown in FIG. 50(B) will be explained.

The Sv free layout allows layout of rectangular areas and layout of non-rectangular areas.

First, the "free layout" of the rectangular area will be explained, and then the layout of the non-rectangular area will be explained. The rectangular and non-rectangular areas can also be output together during image formation.

The Sv free layout of the rectangular area starts with the second
The point pen 421 of the digitizer 16 shown in FIG. 3 indicates an area. Next, the Sv index Nα is designated as H in FIG. 50(B) or as shown in FIG.

By repeating this instruction, the layout positions of a plurality of 87 images and the corresponding index magnets are specified.

Next, by pressing the start key on the operation unit 20, the 87 images of the index fish set above are loaded into the image storage device 3 and printed out according to the predetermined layout information. The details are the same as those for fixed layout printing described above, so they will be omitted.

The Sv free layout of the non-rectangular area is shown in Figure 50 (B).
It functions by pressing a non-rectangular key in the F diagram. Four types of non-rectangular area settings can be selected: circle, oval, R rectangle, and free. These selections are made according to the diagram in FIG. 50(B).

When laying out a circle, the center of the circle is indicated with the point pen 421 of the digitizer 16 as shown in Figure 0 of FIG. 50(B). Similarly, after specifying the radius of the circle as shown in Figure P, by pressing the OK primary key, the index Nα of Sv is selected according to H in Figure 50 (,b) or Figure 1.

Here, the information on the circles indicated in Figures 0 and 50 of Figure 50 passes from the digitizer 16 through the signal line 505 and is stored in the bitmap memory 91 of the color reader l.

Next, by pressing the start key on the operation unit 20, the 87 images of the specified index fish are imported into the image storage device 3, and the bitmap memory 91 of the color reader l is loaded.
The image storage device 3 performs layout and scaling based on the position and size of the circle stored in the color reader Sv.
transfer image information.

The color reader l outputs a circle area signal from the bitmap memory 91 in which circle information is stored in synchronization with the color printer 2, and switches the synthesis circuit 115 in the video processing unit 12 of the color reader l. . If it is outside the circle area, the synthesis circuit 115 outputs 0OH (white), and if it is inside the area, it outputs the image information from the image storage device 3 and transfers it to the color printer 2. This situation is shown in Figure 50 (D
) is shown.

At this time, the image storage device 3 performs scaling so that the diameter of the date information in the bitmap memory 91 is equal to the shorter aspect length of the image information to be output.

As shown in FIG. 50(D), the scaled output image from the image storage device 3 is cut out into a circle based on the bitmap area information, and the color printer 2 forms the image.

Next, a non-rectangular free layout will be explained.

In FIG. 50(B), the function is activated by pressing the free key.

The free layout information is written into the bitmap memory 91 of the color reader 1 by tracing the top surface of the digitizer 16 with the point pen 421 of the digitizer 16. This situation is shown in FIG. 50(D). The image forming process is the same as that for the circle described above, so it will be omitted.

The Sv composite print shown in FIG. 50(B) will be explained. As with the free layout described above, the layout area can be specified as a rectangular area or a non-rectangular area.

The designation of the layout area and the designation of the index Nα are as follows:
This layout is omitted because it is similar to the Sv free layout described above.

Next, by pressing the start key on the operation unit 20, the 87 index images set above are imported into the image storage device 3, and the 87 images are placed inside the predetermined area and outside the area; The images of the reflective original 999 above are combined and printed out.

The Sv index display, Sv index print, and Sv layout print have been described above, and an operation that combines these will be described.

The operation flow is shown in FIG. 50(E). This flowchart shows the operation for selecting an index mark during Sv layout by displaying the Sv index or displaying the Sv index print.

First, in order to perform the Sv layout, as shown in Fig. 33 (C)
34 (B) or Sv index printing shown in FIG. 34(B) is performed.

Next, the operation for performing the S■ layout is started, and the Sv fixed layout, Sv free layout, and Sv composite layout are selected. The details are omitted as they have been described above.

Images of each layout area are selected by the above-mentioned Sv index display or Sv index print, and are shown in FIGS. An index Nα is specified.

At this time, since the image information of the Sv jacket is formed on the monitor or copy paper by Sv index display or Sv index print, it is possible to specify a desired image.

After repeating this operation and storing a plurality of images in the memory, image formation is performed by pressing the start key on the operation unit 20. Image formation has been described above and will therefore be omitted.

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.

The interface with the host computer 33 is performed by a GP-IB controller 4310 connected by a connector 4580. GP-IB controller 431
O is connected to the CPU 4360 via a CPU bus 9610, and is capable of exchanging commands and transferring image data with the host computer 33 according to a predetermined protocol.

Image data from the color reader 1 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 a storage area within the host computer 33, and subjected to enlargement/reduction processing, etc. , Cutting out a portion of image data and laying out multiple image data have been conventionally performed. However, in that case, the amount of color image data is quite large, so even through a general-purpose interface such as GP-IB, the data transfer time between the color reader 1°Sv recorder/player 31 and the host computer 33 is extremely long. It takes a while. 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 GP-IB controller of the image storage device 3.
The U4360 decodes the command and sends it to the color reader L or S.
By controlling the input image data of the v-recording/playback device 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 to the host computer 33. No need to transfer data.

Further, even if the input image data is not stored in the storage area within the host computer 33 according to a command from the host computer 33, the image storage device 3 can store the input image data in the image memory 4060A.
-R, 4060A-G, 4060A-B, it is possible to store multiple image data, and image processing such as layout and enlargement/reduction of each image can be performed by the host computer 33.
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 smaller, so when outputting the registered image file to printer 2, etc., the quality will improve. do.

The image file name that the CPU 4360 uses as a key when image data is input from a human-powered device such as the reader 1 and the computer 33 is determined by the command 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 is composed of eight characters (ASCII 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) (45()0,4
When an image from 510°452OR, G, B, S) is input and registered in the registration memory, the input image will be registered as an image as shown in FIG. The input image at this time is
600 pixels in the X direction (w i d t h ), Y
The direction (height) is input with a size of 450 pixels.

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 GP-IB 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 the 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 1. Analog input 4500.4510°452O
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 SCAM 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. , input control as an RGB luminance image,
It is registered in the image storage device as RGB type image data.

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 AND (4060A to D) of the registration memory are configured as shown in FIG.
0A), 2 images (4060A-R), 0 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), which is composed of 3 frames of R, G, and H. .

Therefore, one pixel on the R plane has 256 gradations (0 to 255), and the three planes R-G-B have 256 x 256 x 2
56 # It has a data structure of 16.7 million colors.

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

The data configuration is arranged in the order of data starting from the upper left on the R side, and this configuration 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
represents magenta, Y represents yellow, and K represents 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, Y.

Each pixel of K has a depth of 8 bits (1 byte), which corresponds to the 4 pixels of C, M, Y, and K.
It has a frame structure.

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.

(Margin below) The data structure is from the top left on page 0. You can add the color you set to.

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

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

The data structure is arranged in order from the top left of the image, and this structure continues in CMYK order.

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 is arranged in the data order specified by the user.

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) of the ζ registration memory.
Figure A).

This image data has an image file name extension of S'″
It is a special file with the image file name “
BITMAP, 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 1 pixel.

Therefore, there are two expressions per pixel: II Q IT and "B". "0" expresses white (no printing), and "1" expresses 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 h direction. he
The light direction is arbitrary.

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

<width>: Width of the image file (width
)<height>: Height of the image file (heig
ht) 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, there are the following types of response data excluding image data.

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 bytes are OOH, is a negative response to each command, and is a response when some kind of error occurs.The first byte is 3DH, and the remaining 2 bytes are OOH. 2 bytes are an error code.

(Error code) = (upper byte) x (100 (HEX
) + (lower byte)・RET type (response with attached information)
The 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 8 bytes in total, and the first byte is a fixed value of the header (02H).

Following the header, the first to seventh data continue one byte at a time, and the content of each data differs depending on the command.

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 can be divided into those that perform a function with a single instruction, 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 4310, 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 devices 1 and 31, and 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.

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 enlargement/interpolation circuit of 50-3.

The 5M0DE command is a command by which the system controller 421O controls read scaling when inputting to the area specified by the 5AREA command.

The ASMODE command causes the CPU 4360 to set the system controller 4210 and counter control 9141 to determine whether the image is input 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,

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 SCAM command, is a command that specifies image file data already registered in the image storage device 3 with parameters indicated as <filename>. Data from memory 4060 is output to the printer via video interface 201. At that time, the output is repeated to the printer for the number of times specified by the parameter indicated as <count>.

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. When combining and outputting multiple layouts, this command sequentially specifies multiple image files, and the CPU 4360 stores memory 4 for each one.
The image file name specified by the MPRINT command is stored in the 370, and when a PRINT or copy command is specified, the CPU 4360 synthesizes multiple layouts of the MPRINT image files held in the memory 4370 and outputs it to the printer 2. do.

The PRPRINT command is sent from the computer 33 to the GP
The image data (widthXheight (size)) sent via the IB interface is
This is a command in which the CPU 4360 registers in the image memory 4060 the file name specified by the parameter indicated as ``lename'', and outputs it directly to the printer through the same operation as the PRINT command.

The DR3CAN command converts image data from color reader 1 into a specified size (width x height
) < filename on the read image memory 4060
> and sets the SCAMC0P command attribute data in the image file management table. Then, the data is further transferred to the computer 33 via the GPIB interface 4580.

Next, the file operation command shown in FIG. 77 will be explained.

The DELE command is a command for deleting, from the image file management table 4361, the image file specified by the parameter indicated as <filename> among the image files already registered in the image storage device 3. At that time, the free space in the image memory after deletion is
The PU 4360 determines from the management table 4361 that the RE

Send via IB.

The DKCHECK command checks whether an image of the image file type (CMYK, RGB, 8-bit palette, binary bitmap) specified by the type parameter can be secured in the image memory in the image storage device 3 with an image size of width x height. determines from the image file management table 4361, sets whether it can be secured in the RET type response data, and sends the remaining capacity after securing to the party that sent the DKCHECK command, such as the computer 33, as RET response data to the GPIB.
Send via.

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

The FNCHECK command is <filename>
It is checked whether the image file specified by the parameter indicated by the parameter exists in the image file management table 4361, and whether or not it exists is set in the RET response data and returned 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 that changes the name of the image file set in the image file management table, and the image file name before change < Sfilename
This is a command to change <Dfilename> to the changed <Dfilename>.

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

The LOAD command loads the data of the image file specified by the parameter indicated as <filename> among the commands registered in the image storage device into the image memory 40.
This is a command to be transferred from 60 to computer 33 via GPIB.

The 5AVE command is the opposite of LOAD, and loads the data of the width x height image size on the computer,
Image data is registered in the image storage device 3 using the file name of the <filename> parameter. first,
This is a command for the CPU 4360 to set the file name, image type, and image size in the image file management table 4361, and to set the image data sent from the computer into the free area of the image memory 4060.

The PUT command is specified by the parameter indicated as <filename> that is already registered in the image storage device 3, and the upper left coordinates (sx,

FIG. 80 shows other commands.

The MONITOR command sets the display controller 4440 for through display, which directly flows data to the analog outputs 4590R, G, B, and S for the analog input specified by the 5SEL command according to the <type> parameter. . In addition, the type variable is, for example, "0" (through display is set), "l"
(Set monitor mute) etc.

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

In the PPRREQ command, the CPU 4360 obtains information on the paper size currently set in the color printer 2 from the control unit 13 via the video interface 201°, and transmits paper discrimination data 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) I/O execution command 5CAN, DR3CAN, PRINT, MPRINT.

DRPRINT becomes.

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

First, use the input/output selection command to select the input/output device, and then
The PU 4360 analyzes the command and returns ACK/NAK as response data 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 input/output status setting 1 is set to the default value. If you want to set a specific input/output state when executing input/output, set (
(for each basic type), it is necessary to execute the input/output status setting command.

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 will not be explained here.

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 FNCHECK 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 input/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. At the time the CPU 4360 analyzes this PRINT command, the CPU 4360 stores the image files in the order of the image file names sent to the MPRINT commands on the RAM.
transfers designated image data from the image memory to the color printer from the image file management table 4361 and outputs it. The combined output at that time is as described above.

Sending MPRINT from computer and PRIN
In the order of image composition using the T command, as shown in FIG. 88, the image specified later is given priority.

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 image file names specified in the RINT and PRINT commands and send it, the CPU 4
360 performs synthesis of a plurality of image files and binary bitmap data as described above. Note that in this embodiment, the binary bitmap image has dots of "1" and "1".
" is basically black, and "0" is switched so that output of other image files is given priority.

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.

The image compositing function includes an image file, a binary bitmap BITMAP, and a special file of S''.
It is possible to combine and output the reflected originals of one copy of the reader, and perform the above-described combining operation.

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.

Specify multiple image files using the MPRINT command, and finally send the copy command to complete the process.The CPU 4360 gives instructions for the copy operation to the CPU on the color reader side, and then specifies the image files and the reader using the MPRINT command. It is possible to combine and output the reflected originals.

“BITMAP, S” in MPRINT (7)
If you specify an image file, 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 commands sent from the computer and the output results from the actual printer are 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.
E: lman F, GAMMA: I7nd, BITCOL
There is an OR 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, and 8-bit data for each of RGB is set.

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 sympathizer.

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, the PALETTE command must be set from the computer, and then, for example, 256X3 (768) as shown in Fig. )<PRIN to set the RGB palette table data for 1 to the palette table of the image storage device 3 via the GP-IB4580
When the T/MPRINT command is executed, R, G,
B component respectively LUT4110A-R, 4110A-
G.

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.
, 4110A-B, the luminance information of the 8-bit palette is converted into density information, which is sequentially output to the above-mentioned image output system, and then output 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, sequentially (repeated).

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 virtual output using the command, the CPU 4360 temporarily registers the color palette data (768 bytes) in the memory 4370 of the image storage device 3 using the PALETTE command.

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 LUT411OA-R.

The brightness slope is B for 4110A-G and 4110-B.
It is set by the values of ±50% of the CI, C2, and C3 parameters of the ALANCE 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.
B type image file data is registered in the memory 4370 in advance so that the color reproduction on the CRT can be performed with the printer 2 output for the γ = 0.45 correction data that takes into account the light emission characteristics of the CRT. 411OA-R of the LUT data.

By setting 4110A-G and 4110A-B and adding a conversion calculation from brightness to density, it is possible to reproduce and output the color of RGB image data subjected to CRT correction of γ=0.45.

The BITCOLOR command uses binary bitmap memory (special file “BITMAP,S”) (27th
For memory E) in figure (A), the upper left (sx.

The parameter of 1ndex is that the CPU 4360 uses memory 4.
It is possible to hold more than one on 370. Then, actually use the MPRINT or PRINT command to print f.
When the file name "BITMAP, S" is specified for ilename, the CPU 4360 uses the CPU 22 of the control unit 13 of the color reader 1/color printer 2.

3-byte color data of the RGB components in the color palette table 4362 corresponding to the parameter of the area eight and the corresponding color palette index number (index parameter) is transmitted, and (if multiple areas are specified by the BITCOLOR command) (repeat sequentially if necessary), control unit 1
3 sets these parameters in the programmable compositing unit 115 to enable coloring of a designated area in 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

Binary bitmap data of AP and S' (Figure 27 (A)
It is possible to color and output the memory E) of the computer 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.

In the image recording device remote state, 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, and remote specification from the operation panel of color reader 1 or REMOTE from the host computer The device enters the remote state when instructed by a 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 1. 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
By communicating with the CPU 22 of the control unit 13 of the color printer 2 and color reader 1 via the video interface 201, the PU 4360 can instruct the aforementioned four remote/local states from the computer.

<Control related to remote/local> Switching between remote/local states and control of the system in each state will be explained using FIGS. 99 to 101.

Figure 99 shows the control unit 1 in the color reader.
3 (hereinafter abbreviated as blade radar controller) is a control flow regarding the remote/local state of the controller. First, p
When "ower" is on, it communicates with the system controller 4210-2 in the image storage device in 5 lots and receives the system status at that time.Next, in 3102, it is determined whether the system is in a system remote state, and if so,
In step 5103, a message as shown in A of FIG. 101 is displayed on the liquid crystal touch panel on the operation unit 20 of the color reader. At this time, keys on the operation unit 20 other than the remote key 20-1 shown in the first figure cannot be accepted. Next, at 5104,
It is determined whether a remote/local state switching command has come from the system controller 4210-2, and if so, the system controller 421O-
2 to the specified state. In this switching process, if the color reader is already operating in a predetermined state, for example if it is operating as a copying machine, switching cannot be performed. Furthermore, there are cases in which an attempt to perform switching may actually result in an abnormal operation, resulting in a malfunction. In that case, the system controller 4210-
Let 2 know that you failed.

At step 5105, it is determined whether or not another command shown in FIG. 71 or FIG. Executes printing, composite printing, etc.

In step 5106, it is determined whether the remote key on the color reader side has been pressed, and if it has been pressed, a request is made to the system controller 4210-2 to switch between remote and local states. This switching changes the system remote state to the remote state of the image storage device from the color league, and the system controller 4210-2 performs the switching if switching is possible, and if the switching fails, the color reader controller 13 Let me know. If the color reader controller 13 fails, it displays the message shown in FIG. 101B.

Next, when it is determined in step 5102 that the system status is not the system remote status, all keys on the operation unit 20 become valid. 5ilo determines whether a remote/local state switching command has been received from the system controller, and if so, performs switching processing to the specified state at Sl 16 in the same manner as 5109.

In step 5ill, it is determined whether a key (key for using the image recording device) on the operation unit 20 has been pressed.

These keys are keys on the operation screen that are called up by the external device key 20-2 on the operation unit 20. When this key is pressed, it is first determined in 5112 whether the remote/local state is the copy machine remote state, and If so, Sl
At step 14, the image storage device 3 is controlled to perform processing according to the input key operation. On the other hand, if the copying machine is not in the remote state, it communicates with the system controller 4210-2 in step 5113 to perform switching processing to the copying machine remote state. If this switching is successful, the process proceeds to Sl 14, and if it is unsuccessful, a message 10111C is issued.

5115 determines whether any other key has been pressed, and if so, 5l14 is the color league.

Controls the color printer and performs key processing.

FIG. 100 is a control flow regarding the remote/local state of the system controller 4210-2 in the image storage device 3. First, it is determined in 8201 whether a command from the host computer has been received, and if so, it is determined in 5203 whether it is a REMOTE command, and if so, in 5204, communication is performed with the controller 31 on the color reader side, and remote control is performed. /Perform local state person switching processing. Next, at 8205, the received command is a command that uses only the image storage device, e.g.
Determine whether it is an AVE command, LOAD command, etc.
If so, it is determined in 5206 whether the remote/local state is an image storage device remote state or a system remote state. In these states, the image storage device is available for use by the host, so the command sent from the host is executed in step 5208.

On the other hand, when these states are not present, communication is performed with the color league in step 5207, and remote/local state switching processing is performed. If the switching is successful, the process returns to 8208 (but if it is unsuccessful, the host is notified of the failure and the command is not executed).

8209 means that the command received from the host is a command that is also used by a color reader/color printer, such as P
It is determined whether it is a RINT command, a 5CAN command, etc., and if so, it is determined in step 5210 whether the remote/local state is a system remote state.

In this state, the color reader/color printer is available for use by the host. Therefore, the command is executed while communicating with the color league controller at step 5212.

At this time, the image data is only transferred between the color league and the image storage device or between the image storage device and the color printer, and the control is performed by the system controller 4210-2 and the league controller 13 in accordance with commands from the above-mentioned host. During this time, the host does not need to control the system and can do other work.

Note that the host communicates with the system controller as necessary to check whether the job has been completed.

On the other hand, when it is not in this state, it communicates with the color league controller in step 5211 and performs remote/local state switching processing.

In 5202, it is determined whether there is a command from the color league, and if so, in 5213 it is determined whether it is a remote/local state switching request, and if so,
At step 5214, switching processing is performed. In the case of other commands, it is determined in step 5215 whether the remote/local state is the copying machine remote state. In this state, since the image storage device 3 is enabled by the color league controller, the command from the color league controller is executed in step 5216. On the other hand, when not in this state, 52
17, the color league is notified of the error.

In the present embodiment described above, for example, during image transfer between the host and the image storage device 3, the color league side can operate in the local mode. Therefore, even if it takes time to transfer the image from the host to the image storage device 3, the league side can perform the copying operation during this time.

Conversely, the image storage device 3 can be controlled from the color league while data is not being transferred from the host to the image storage device 3. Even if the color league is image storage device 3
Even if the image storage device is not controlled, by turning on the remote key on the color league side, the image storage device can be placed in a remote state regardless of the host.

In addition, the color league outputs an instruction to the image storage device to store the image signal of the Sv reproducing machine, for example, to store the Sv multi-index image as described above, and while this storage is being performed, the color league 1 Normal local mode operations can be executed.

Next, FIGS. 84 to 87 show the above-mentioned command transmission procedure (some examples are shown).

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 DR8CAN command.

No. 87 is the opposite of the DR5CAN command in FIG. 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, a 1024x768 pixel RGB type image is 277x19 from the top left (10,10) mm position of the paper.
An example in which printout is performed by centering within a range of 0 mm will be described.

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

In this example, two RGB type images of 1280X'1024 and 1024X768 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 1000 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-type sensor may be used. It 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.

As explained above, in this embodiment, the desired track number and layout information at the time of image formation are set in advance from the Sv floppy disk in which multiple image information taken by the Sv left camera are recorded, and the copy start key is turned on. The images of the track numbers of the Sv floppy are played back and stored one after another in the memory. When all the images of the desired track are stored in the memory, the printer is automatically started, and when the printer is synchronized, image information is output from the memory according to the preset layout information, and the reader It is extremely easy to use, as image formation on the reflective original by layerer linking and compositing of the image from the reader and the image in memory are performed continuously by pressing the copy start key. Furthermore, since image registration in the memory is performed only for images selected by track numbers, the capacity of the memory is relatively small (and it is easy to control writing to the image memory).

In the embodiment described above, a medium called an Sv floppy was used as a recording medium capable of storing a plurality of images, but the present invention is not limited to such an Sv floppy, but various other media such as a solid state memory such as a semiconductor memory can be used. It may be a memory or an optical memory such as an optical disk.

Furthermore, various configurations may be adopted depending on the type of medium used as a reproducing means for reproducing from a recording medium.

Further, in order to select a plurality of desired images from a plurality of images, the selection means is designated by specifying the index number on the screen D or H shown in FIG. 50(B).

In addition, in this embodiment, before making such a designation, it is possible to display the Sv floppy image on a multi-screen on the monitor as shown in FIG. Since this is carried out using a memory M having a relatively small capacity, the configuration can be simplified.

Further, in this embodiment, a color reader is used as the document reading means, but such a color reader may of course be capable of reading a single color.

Further, in the present embodiment, a so-called frasitopesito type reading device is used, but the present invention is not limited to this, and a reading device using a two-dimensional sensor may be used.

Furthermore, in this embodiment, the storage means for storing reproduced images from the reproduction means is composed of memories A, B, C, and D.

Furthermore, in this embodiment, in response to an image formation instruction, the plurality of images selected by the selection means are sequentially reproduced by the reproduction means, sequentially stored in the storage means, and then the images read from the storage means. The image forming means for forming an image as a visible image is an image forming apparatus that performs image formation according to the flowchart shown in FIG. 50(C).

Further, in this embodiment, an electrophotographic image forming means was used, but such image forming means may include an inkjet method, an inkjet method,
Various configurations can be used, such as a thermal system, a one-way system, or a monitor display.

〔Effect of the invention〕

As described above, according to the present invention, a desired image can be combined with a document image and formed as a visible image with a simple configuration.
