 The details will be described below for each unit.

<Description of Color Reader 1> First, the configuration of the color reader 1 will be described.

In the color reader 1 shown in FIG. 1, reference numeral 999 denotes a document, reference numeral 4 denotes a platen glass on which the document is placed, and reference numeral 5 denotes a full-color full-color sensor for condensing a reflected light image from the document exposed and scanned by a halogen exposure lamp 10. 6 is a rod array lens for inputting an image. An original scanning unit 11 includes a rod array lens 5, a 1: 1 full-color sensor 6, a sensor output signal amplification circuit 7, and a halogen exposure lamp 10 integrated with each other.
The document 999 is exposed and scanned in the direction of the arrow (A1).
The image information to be read for the original 999 is the original scanning unit 11
Are sequentially read line by line by exposing and scanning. The read color separation image signal is amplified to a predetermined voltage by the sensor output signal amplification circuit 7 and then input to the video processing unit via the signal line 501, where the signal is processed. Note that the signal line 501 has a coaxial cable configuration to guarantee faithful transmission of a signal. A signal 502 is a signal line for supplying a drive pulse for the 1: 1 full-color sensor 6, and all necessary drive pulses are generated in the video processing unit 12. Reference numerals 8 and 9 denote a white plate and a black plate for correcting the white level and the black level of the image signal, respectively. By irradiating with a halogen exposure lamp 10, a signal level of a predetermined density can be obtained. Used for white level correction and black level correction.

Reference numeral 13 denotes a control unit for controlling the entire color reader 1 according to the present embodiment having a micro computer. The control unit 13 controls display and key input on the operation panel 20 via the bus 508, and controls the video processing unit 12. The signal lines 509 and 510 are output by the position sensors S1 and S2.
, The position of the original scanning unit 11 is detected.

Further, a stepping motor driving circuit 15 for pulse-driving a stepping motor 14 for moving the scanning body 11 by a signal line 503 is controlled by an exposure lamp driver 21 via a signal line 504 to control ON / OFF of the halogen exposure lamp 10. , And controls the color reader 1 such as control of the digitizer 16 and the display unit via the signal line 505.

Reference numeral 20 denotes an operation unit of the color reader unit 1, which includes a liquid crystal display panel also serving as a touch panel and keys for giving various instructions. The display example of the display panel is shown in FIG. 47 and thereafter.

The color image signal read by the above-described original scanning unit 11 during the original exposure scanning is input to the video processing unit 12 via the sensor output signal amplification circuit 7 and the signal line 501.

Next, the details of the original scanning unit 11 and the video processing unit 12 will be described with reference to FIG.

The color image signal input to the video processing unit 12 is separated into three colors of G (green), B (blue), and R (red) by the sample / hold circuit S / H43. Each of the separated color image signals is converted into an analog signal by an A / D converter 44.
It is digitally converted to a digital color image signal.

In the present embodiment, the color reading sensor 6 in the original scanning unit 11 is formed in a staggered shape divided into five regions as shown in FIG. Using the color reading sensor 6 and the shift correcting circuit 45, the reading position shift between the 2,4 channel that is pre-scanning and the remaining 1,3,5 channel is corrected. The corrected signal of the displacement from the shift correction circuit 45 is input to a black correction circuit / white correction circuit 46, and color reading is performed using the signal corresponding to the reflected light from the white plate 8 and the black plate 9 described above. The unevenness in darkness of the sensor 6, the unevenness in the light amount of the halogen exposure lamp 10, the variation in sensitivity of the sensor, and the like are corrected.

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

The video interface 201 has the functions shown in FIGS. 3 to 6. That is, (1) the function of outputting the signal 559 from the black correction / white correction circuit 46 to the image storage device 3 (FIG. 3), and (2) the image information 563 from the image storage device 3 to the selector 119.
(FIG. 4) (3) Image information 562 from the synthesis circuit 115 is stored in the image storage device 3.
(FIG. 5) (4) Combining the binary information 206 from the image storage device 3 with the synthesizing circuit 1
Function to be input to 15 (FIG. 6) (5) Control line 207 (line of HSYNC, VSYNC, image enable EN, etc.) between image storage device 3 and color reader 1
And connection of communication line 561 between CPU and CPU. Especially the CPU communication line is the communication control 162 in the control unit 13.
And exchanges various commands and area information.

It has the following five functions. The selection of these five functions is switched by the CPU control line 508 as shown in FIGS.

As described above, the video interface 201
Has five functions, and the signal lines 205, 206, and 207 are capable of bidirectional transmission.

With this configuration, bidirectional transmission is possible, and the number of signal lines can be reduced, the cable can be made thinner, and the cost can be reduced.

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, it is possible to reduce the number of connection lines between the devices constituting the system, and to perform high-level communication with each other.

The image information 559 from the black correction / white correction circuit 46 is
The data is input to a logarithmic conversion circuit 48 (FIG. 2) for performing processing for matching with the relative luminous efficiency characteristics of human eyes.

Here, white = 00 _H, is as much as possible converted black = FF _H, the image source further input to the image Yomitoi sensor, for example, a normal reflective original, transparent original such as a film Puroji EKTAR, also with the same transparent original negative As shown in FIGS. 7 (a) and 7 (b), a plurality of LUTs (lookup tables) for logarithmic conversion are used because the sensitivity of the film, the positive film or the film and the gamma characteristics input in the exposure state are different. Have it and use it properly according to the application. The switching is performed by the signal lines lg0, lg1, lg2, and is performed by inputting an instruction from an operation unit or the like as an I / O port of the CPU 22. Here, the data output for each of B, G, R corresponds to the density value of the output image, and B (blue), G (green), R
Since the signals of (red) correspond to the amounts of yellow, magenta, and cyan toner, respectively, the color image data thereafter is associated with Y, M, and C.

The color conversion circuit 47 receives input color image data.
This circuit detects a specific color from R, B, and G and replaces it with another color. For example, a function of converting a red portion in a document into blue or any other color is realized.

Next, the color correction circuit 49 performs color correction on the respective color component image data from the original image obtained by the logarithmic conversion 48, that is, the yellow component, the magenta component, and the cyan component as described below. As shown in FIG. 8, the spectral characteristics of the color separation filter arranged for each pixel in the color reading sensor have an unnecessary transmission area such as a hatched portion, while, for example, the color transferred to the transfer paper It is well known that the toner (Y, M, C) also has an unnecessary absorption component as shown in FIG. In the drawing, only R and G and Y and M are shown.

Therefore, for each color component image data Yi, Mi, Ci, Masking correction for calculating a linear expression of each color and performing color correction is well known. Furthermore, by Yi, Mi, Ci, Min (Yi, M
i, Ci) (the minimum value of Yi, Mi, and Ci) is calculated as a sum (black), and black toner is added later (smearing). Under color removal (UCR) operations, which reduce the amount added, are also common. Fig. 10 (a)
The circuit configuration of the color correction circuit 49 for performing masking, darkening, and UCR is shown in FIG. The feature of this configuration is that it has two masking matrices and can switch at high speed with "1/0" of one signal line. With or without UCR, one signal line "1/0" It has two circuits for determining the amount of smear that can be switched at high speed, and can be switched at high speed with "1/0".

First, prior to image reading, desired first matrix coefficients M ₁ and second matrix coefficients M ₂ are set from a bus connected to the CPU 22. In this example In and, M ₁ is the register 50 to 52, M ₂ is set to the register 53-55.

Reference numerals 56 to 62 denote selectors, respectively.
When "1", A is selected, and when "0", B is selected. Therefore, when selecting the matrix M ₁ switching signal MAREA566 = "1"
To, to "0" If you want to select the matrix M _2.

Reference numeral 63 denotes a selector, and the selection signals C ₀ , C ₁ (567, 5
68), outputs a, b, c based on the truth table in FIG. 10 (b).
Is obtained. The selection signals C ₀ , C ₁ and C ₂ correspond to the color signals to be output, for example, in the order of Y, M, C, Bk (C ₂ , C ₁ , C ₀ )
= (0,0,0), (0,0,1), (0,1,0), (1,0,0) Obtain color signals that have been color corrected. The CPU 22 generates C ₀ , C ₁ , and C ₂ according to the image forming sequence of the color printer 2. Now, (C ₀ , C ₁ , C ₂ ) = (0,0,0) and MAREA566 =
When "1", the output of the selector 63 (a, b, c) , the register 50a, 50b, the content of 50c, thus _{(a Y1, -b M1, -c} C1) is output. On the other hand, Min (Yi, Mi, C
i) = black component signal 570 calculated as = k
Ax-b (where a and b are constants) undergoes a primary conversion, and is input to the B inputs of subtractors 65a, 65b and 65c (through selector 60). In each of the subtracters 65a, 65b and 65c, Y = Yi− (a
k−b), M = Mi− (ak−b), and C = Ci− (ak−b) are calculated, and the multipliers 66a, 66b, 66m for the masking operation are calculated via the signal lines 571a, 571b, 571c. Entered at 66c. Selector 6
0 is controlled by the signal UAREA 572, and the UAREA 572 has a configuration in which UCR (under color removal), presence / absence, and “1/0” can be switched at high speed.

The multipliers 66a, 66b, and 66c have (A _Y1 ,
−b _M1 , −c _C1 ) and B input as described above [Yi− (ak−b),
Mi− (ak−b), Ci− (ak−b)] = [Yi, Mi, Ci], so that it is clear from the figure that the output Dout has the condition of C ₂ = 0 (Y or M or C selection) and Yout = Yi
× (a _Y1 ) + Mi × (−b _M1 ) + Ci × (−c _C1 )
Yellow image data that has been subjected to masking color correction and undercolor removal processing is obtained. Similarly _{Mout = Yi × (-a Y2)} + Mi × (b M2) + Ci × (-c C2) Cout = Yi × (-a Y3) + Mi × (-b M3) + Ci × (c C3) within Dout Is output. The color selection is controlled by the CPU 22 in accordance with the order of output to the alert printer (C ₀ , C ₁ , C ₂ ) according to the table of FIG. 10 (b). Register 6
7a, b, c, 68a, b, c are registers for monochrome image formation,
Based on the same principle as the masking color correction described above, MONO =
Each color is obtained by weighted addition using k ₁ Yi + l ₁ Mi + m ₁ Ci.

Switching signal MAREA566, UAREA572, KAREA573 the switching speed coefficient matrix M ₁ and M ₂ of the masking color correction as described above, UAREA572 is UCR There, the switching speed without, KAREA573 the black component signal (signal line 574 → Selector 6
1 to Dout), primary conversion switch, i.e., for k = Min (Yi, Mi, Ci), Y = ck-d or Y
= Ek-f (c, d, e, and f are constant parameters) a signal that switches the characteristics at high speed. For example, a masking coefficient may be changed for each area in one copy screen, or the UCR amount or the sum amount may be changed for each area. It is configured to be able to switch with. Therefore, images obtained from image input sources having different color separation characteristics, a plurality of images having different black tones, etc.
This is a configuration that can be applied when combining images as in the present embodiment. Note that these area signals MAREA, UAREA, KAREA (566, 57
2,573) is generated by a region generating circuit (FIG. 69) described later.

Next, a black character processing circuit for improving black reproduction of black characters and thin lines in a document and color bleeding of an edge portion of black characters and black thin lines will be described with reference to FIGS. 11 and 12. FIG.

The black level / white correction circuit 46 shown in FIG.
R, G, B (red, green, blue) color signals 559R, 559G, 559B of which white level has been corrected are subjected to LOG conversion 48, masking, under color removal 49, and then the color signals to be output to the printer are The signal is selected and output to the signal line 565. In parallel with this, a luminance signal Y and a chrominance signal are used to detect an achromatic portion of an original and a portion that is an edge portion (that is, a portion that is a black character and a black thin line) from the signals R, G, and B. I, Q to Y,
It is calculated by the I, Q calculation circuit 70 (FIG. 11).

The luminance signal Y575 is input to a line buffer circuit 71 for five lines in order to calculate a 5 × 5 matrix by a well-known digital second-order differentiating circuit 72 for extracting an edge signal. At 72, a Laplacian operation is performed. In other words, when the input luminance signal Y is a step-like input (for example, a character portion) as shown in i) of FIG.
(Hereinafter referred to as edge signal). Look-up tables LUTA73a and LUTB37b are black letters (or black thin lines)
This is a look-up table for determining a print amount (for example, a toner amount) in the edge portion of FIG. 12, and is constituted by a look-up table having characteristics as shown in FIGS. 12 (a) and 12 (b), respectively. That is, when LUTA acts on the edge signal 576, the amplitude increases as shown in FIGS. 12 (d) and (iii), which determines the amount of black toner in the black edge portion as described later. Also, LUT is applied to edge signal 576.
When B acts, the absolute value becomes negative, which determines the toner amount of Y, M, C (yellow, magenta, cyan) in the black edge portion. This is a signal as shown in FIG. 12 (d) (iv), and becomes a signal as shown in FIG. 12 (v) by passing through a smoothing (averaging) circuit 74.

On the other hand, the achromatic color detection circuit 75 is a circuit that outputs a signal in accordance with the characteristics as shown in FIG. 12, for example, so that the output becomes 1 for a complete achromatic color and the output becomes 0 for a chromatic color. The signal 579, which is selected by the selector 76 at the time of black toner printing by the signal 577 which becomes "1" at the time of black toner printing, passes through the signal 578, and determines the black toner amount at the multiplier 77,
After multiplication with (FIG. 12 (d) (iii)), the adder 78 adds it to the original image signal.

On the other hand, when printing 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 thin line portions.
Thus, the selector 76 outputs “1” to the multiplier, the selector 79 outputs a signal (FIG. 12 (d) (v)) obtained by smoothing the output from the LUTB736, and the adder 78 outputs FIG. d) The same signal as in (v) is input, and the signal is subtracted from the original signal only from the black edge portion.

In other words, this means that the signal for determining the amount of black toner for the black edge portion is strong, that is, the amount of black toner is increased, and the amount of Y, M, and C toner for the same portion is reduced, so that the black portion is reduced. That is to express it more black.

Signal 581 obtained by binarizing achromatic signal 580 by binarizing circuit 80b
Is "1" for an achromatic color and "0" for a chromatic color. That is, as described above, in the selector 79, when printing black toner (when 577 = “1”), the S input = “1”, and the A input,
That is, 579 (FIG. 12 (d) (iii)) is output, and the black edge is emphasized. When printing Y, M, C toners (577 = "0"), the signal 581 = "1". Therefore, if the color is achromatic, the B input is selected to reduce the toner amounts of Y, M, C as described above. ,
12 (d) and (v) are output. In the case of a chromatic color, the signal 581 = 0, therefore, ▲ ▼ = 1, that is, the S input of the selector 79 becomes 1, and A is selected. The signals shown in FIGS. 9D and 9C are output to the adder 78, and the well-known edge enhancement is performed.

As shown in FIG. 12 (a), two types of LUTs are prepared for the LUTA 73a: an LUT that becomes zero when the edge signal value is less than ± n and a LUT that becomes zero when the edge signal value is less than ± m. A value to be clamped to zero is selected according to the level of the original signal 565, that is, the density of the original at this time. When the density level of the original is higher than the value set by the CPU 22 via the bus 508, that is, when the density level is higher, the comparator
The output of 81 becomes "1", and the LUT which is clamped to zero at A 'and B' in FIG. 12 (a) is less than a certain density, that is, when the output of the comparator 81 is "0", By selecting the LUT that is clamped to zero by A and B, the effect of noise removal according to the density range is changed.

Further, the output 583 of the AND gate 82 is a further improvement for the edge portion of the black character, and 584 (B input) for Y, M, C printing for the edge portion of the black character, and otherwise for the edge portion of the black character. This is a signal for switching to select 585. The signal 586 input to the AND gate 584 is converted to the edge signal by LUTC.
(FIG. 12 (c)) A binarizing circuit for a signal having the characteristic shown in FIG.
It is binarized at 80a, that is, it is "1" when the absolute value of the edge signal is equal to or greater than a predetermined value, and is "0" when it is equal to or less than the predetermined value.
Therefore, 587 = “1”, 581 = “1”, and 588 = “L” are achromatic, when the edge signal is large, that is, at the edge portion of the black signal, and Y, M , C only when printing toner. Therefore, at this time, as described above, the signal for determining the toner amounts of Y, M, and C is reduced from the original signal only in the portion corresponding to the black edge, and further, the averaging circuit 84 Is smoothed, and is output to 589 through the selector 83 when the signal ER = "1". Otherwise, a normally edge-enhanced signal 585 is output at output 589.

The signal ER is controlled by the CPU 22. When ER = "1", the output of the averaging circuit 84 is output to the output 589, and when ER = "0", "0" is output to the output 589. This completely sets the signal of the color toner (Y, M, C) around the edge of the black character to "0" to further eliminate color fringing, and these are selectable.

FIG. 13 is a diagram for explaining area signal generation (MAREA 566, UAREA 572, KAREA 573, etc.) in the area generating circuit 69. The region refers to, for example, a hatched portion in FIG. 13 (e), which is a section in the sub-scanning direction, that is, a timing chart AREA of FIG. 13 (e) for each HSYNC for each line. Is distinguished from other areas.
Such an area is specified by, for example, the digitizer 16 or the like.

FIGS. 13 (a) to 13 (d) show the generation position of this area signal,
This shows a configuration in which the section length and the number of sections are programmable by the CPU 22 and can be obtained in large numbers. In this configuration, one area signal is generated by one bit of a RAM accessible to the CPU. For example, in order to obtain n area signals AREA0 to AREAn, two area RAMs are provided. Yes (first
3 (d) 85A, 85B).

Now, the area signals AREA0 and AR as shown in FIG.
When obtaining EAn, making a "1" in bit 0 of the address of the RAM x _1, x _3, to all bit 0 of the rest of the address "0". On the other hand, “1” is set at the address 1, x ₁ , x ₂ , x ₄ of the RAM
All bits n of other addresses are set to "0". HSYNC in synchronism with the constant clock as the reference, As you read sequentially Shikenshiyaru data RAM, for example, as in the FIG. 13 (c), read data "1" in terms of addresses x ₁ and x ₃ It is. The read data is as shown in FIG.
Since the J-K flip-flops 86-0 to 86-n are in the J and K terminals, the output is a toggle operation, that is, RAM.
When “1” is read out and CLK is input, output “0” →
“1”, “1” → “0”, and a section signal like AREA0,
Accordingly, an area signal is generated. When data = "0" over all addresses, no area section occurs and no area is set.

FIG. 13 (d) shows this circuit configuration, where 85A and 85B are the above-mentioned RAMs. This is because, for example, while reading data from the RAMA 85A line by line to switch the region section at high speed, the CPU 22 performs a memory write operation for a different region setting from the CPU 22 while reading the data from the RAMA 85A line by line. Alternately switches between section generation and memory writing from the CPU. Therefore, when the shaded area in FIG. 13 (f) is designated, RAMA and RAMB are switched in the order of A → B → A → B → A, which is (C ₃ , C ₄ , C ₅ ) =
If (0,1,0), the counter output counted by VCLK is given as an address to RAMA85A through selector 87A (Aa), gate 88A opens, gate 88B closes, and RAMA85A closes.
85A, the entire bit width and n bits are input to the JK flip-flops 86-0 to 86-n, and the interval signals AREA0 to AREAn are generated according to the set values.

During the writing from the CPU to B, the address bus AB
us, the data bus D-Bus, and the access signal /. Conversely With the case of generating the interval signal based on the data set in the _{RAMB85B (C 3, C 4,} C 5) = (1,0,1), performed in the same way, to RAMA85A from CPU Can be written.

Therefore, for example, based on this area signal, it is possible to easily perform processing of the image such as cutting out (trimming) of the image and omitting the frame. That is, the area signal 590 generated as described above by the area generation circuit 69 in FIG.
Selector with the area switching signal ECH591 output from 25
Selected at 89 and input to the input of AND gate 90. This, as is apparent from the figure, for example, FIG. 13 (b), by forming the signal 590 as the AREA0, x ₃ from x ₁
A cutout of the image until, by forming as a AREAn, missing a frame is between the x ₁ to x _2, is a cutout image in the interval from 1 to x _1, x ₂ to x ₄ It will be easily understood.

14 and 15 show the configuration and control timing of the bit map memory 91 for the area limiting mask.
As can be understood from FIG. 2, for example, a detection output 592 of a color conversion circuit described later makes it possible to create an area restriction mask that restricts only a specific color area in a document. A region control mask corresponding to the density value (or signal level) can be created by the signal 593 binarized by the binarization circuit 92 on the basis of the video image signal 560 to be obtained.

FIG. 14 (a) is a block diagram showing details of a bit map memory 91 for an area limiting mask and the control thereof. The mask is configured such that 4 × 4 pixels are one block as shown in FIG. 15, and one block corresponds to one bit of the bit map memory. For example, in an image with a pixel density of 16 pel / mm, 297 mm For × 420mm (A3 size), (297 × 420 × 16 × 16) ÷ 16 ≒ 2Mbit, that is,
For example, it may be composed of a 1 Mbit dynamic RAM and two chips.

Signal input to selector 93 in FIG. 14 (a)
592 and 593 are data input lines for generating a mask as described above.
When the output 593 of the binarizing circuit 92 is selected, first, in order to count the number of "1" in the 4 × 4 block, it is input to the buffers 94A, 94B, 94C and 94D for 1 bit × 4 lines. Is done. FIFO9
4A to 94D, as shown in the figure, the output of 94A becomes the input of 94B,
Is connected to the 94C input, and so on.
Are output to the latches 95A to 95C in a 4-bit parallel manner by VCLK (see the timing chart of FIG. 14 (d)). The outputs 595A of the FIFO and the outputs 595B, 595C, and 595D of the latches 95A, 95B, and 95C are added by adders 96A, 96B, and 96C (signal 596).
The value set via the O port 25 (for example, “12”) is compared with its magnitude. That is, it is determined whether the number of 1s in the 4 × 4 block is larger than a predetermined number.

In FIG. 14 (d), the number of "1" s in the block N is "14" and the number of 1s in the block (N + 1) is "4", so that the output of the comparator 97 in FIG. 597 is a signal 597
Is “1” when is “14” and “0” when it is “4”.
With the latch pulse 598 in FIG.
Is once latched in one block of × 4, Q output of latch 98 is D _IN input of the memory 99, i.e., the mask making data. 100H is an H address counter for generating an address in the main scanning direction of the mask memory. One address is assigned by 4 × 4 blocks, so that the count-up is performed by dividing the pixel clock VCLK by 4 with the frequency divider 101H. Done. Similarly, 100V is an address counter for generating an address in the sub-scanning direction of the mask memory. For the same reason, the frequency divider 101V counts up by the clock obtained by dividing the synchronization signal HSYNC of each line by 4, and outputs the H address, The operation of the V address is controlled so as to synchronize with the operation of counting (adding) "1" in a 4.times.4 block.

Also, the lower 2 bits output of the V address counter, 599,
600 is NORed by NOR gate 102, and clock 60 divided by 4
A signal 602 for gating 1 is generated, and a 4 × 4 signal is generated by the AND gate 103 as shown in FIG. 14 (c).
A latch signal 598 is generated so that only one latch is performed on the block. 603 is a CPU bus 508 (FIG. 2)
604 is an address bus, and a signal 605 is a write pulse WR from the CPU 22. At the time of WR (write) operation from the CPU 22 to the memory 99, the write pulse becomes “Lo”, and the gates 104, 105, 106 open,
An address bus and a data bus from the CPU 22 are connected to the memory 99, and predetermined data is written at random.
When performing WR (write) and RD read sequentially with the address counter and V address counter, use the I / O
The gates 107 and 108 are opened by the control lines of the gates 107 and 108 connected to the port 25, and a sequential address is supplied to the memory 99.

For example, if the mask as shown in FIG. 16 is formed by the output 593 of the binarized output 92, the output 592 of the color conversion circuit, or the CPU 22, the image can be cut out and synthesized based on the area within the thick line frame. It can be carried out.

Next, the mask created in units of 4 × 4 pixels is the edge portion (boundary portion) as shown in (i) of FIG. 17 (b).
However, since it is jagged in units of four pixels, the jagged portion is made smooth by the interpolation circuit 109 in FIG. 2 to make it look smooth.

FIG. 17 (a) shows a block diagram of the interpolation circuit. Reference numeral 110 denotes a selector. The A input is Hi clamp, that is, FF _H is input when it is set to 8 bits, and the B input is GND, that is, 00 _H is input to the B input. Switch. This allows
The input of the interpolation circuit 111 outputs FF _H in the area mask and 00 _{H in the} area mask. This is as shown in (i) of FIG. 17 (b). The interpolation circuit 111 may be any circuit such as a primary interpolation method, a high-order interpolation method, a sinc interpolation method, etc., and a circuit having a known circuit configuration may be applied. Since the output of the interpolation circuit is output in multiple values, the binarization circuit 112
To binarize. As a result, as shown in (ii) of FIG. 17 (b), the original boundary A is made to be B as shown in FIG. Selector 113
Indicates whether to output the mask memory output as it is (select A) or to select and output a mask signal with a smooth boundary after interpolation as described above, which is connected to the I / O port of CPU22. Switching is performed as necessary according to the signal 608. Therefore, for example, the interpolation output is selected by the signal 608,
Further, when the ECH is switched to select the output of the area restriction mask by the selector 89 in FIG.
As shown in FIG. 8A, a non-rectangular figure can be cut out by using a mask. The output of the mask memory of the bit map memory 91 is taken out from the signal line 607 in FIG.
When selected by the selector 114 and synthesized by the synthesizing circuit 115 described later, the result becomes as shown in FIG. 18 (b).

Reference numeral 116 in FIG. 2 denotes a density conversion circuit which can change the density and gradation for each color as shown in FIG. 19, and is constituted by an LUT (lookup table) or the like. 118
This is a repetition circuit and is composed of a FIFO as shown in FIG. Reference numeral 609 denotes an HSYNC shown in FIG. 11B, in which a Lo pulse is input as a line synchronization signal once per line, and
Initializes the internal WR (write) pointer (not shown). 611 is input image data, 612 is output image data, and Repeat 616 is a signal for initializing an RD (read) pointer of the FIFO. Therefore, as shown in the timing chart of FIG. 20 (b), the data 1 to 10 written in the FIFO sequentially are input as a repeat signal 616 as shown in the figure, whereby "→ 1 → 2 → 3 → 4 → 1". → 2 → 3 → 1 → 2
Repeated reading is performed as "3". That is, the same image can be repeated as shown in FIG. 11C by giving the FIFO a repeat signal 616 formed identically for each line. As shown in FIG. 21A, data of "1" is written into the mask area forming memory of the bit map, and the read data is synthesized by the synthesizing circuit 115 in FIG. 1 to form a dotted line (cut line).

As described above, if the repeat signal is controlled by the region generation circuit 69 so as to be generated at the time point shown in FIG. 21A by the repetition circuit 118, a cut line can be formed for the repetition image. "1" as shown in Fig. 21 (B)
By writing the data of (1), it becomes possible to form a darkened area on the image by writing the line as shown in (C). Image signal 612 output from repetition circuit 118
Is input to the image synthesizing circuit 115 and various image processing is performed.

<Synthesis> Next, the details of the synthesis circuit will be described with reference to FIG.

The editing process performed here is independent for each specified area.
This is performed programmably based on the data set in the RAMs 135 and 136 shown in FIG. That is, the processing is performed for each code number (hereinafter, referred to as an area code) obtained from the area code generator 130, which will be described in detail later.

Digitizer is used to specify the above area and various editing processes
16. Edited by the CPU bus 508 through the CPU into the area code generator 130, RAMs 135 and 136, and registers 140 to 142 of FIG. 25 (A-1) through the CPU in response to instructions (commands) obtained from the operation unit 20 and the image storage device 3. The parameters corresponding to the processing are set.

In FIG. 25 (A-1), reference numeral 132 denotes a selector for selecting one of the outputs of the area code generation circuit 130 and the register 131. Note that 130 is an area code generator that automatically generates an area code according to the synchronization signals HSYNC and CLK, and 131 is a register to which a signal from the CPU bus 508 is input. Reference numerals 135 and 136 denote RAMs in which area codes and processing or image data corresponding to the area codes are stored as tables. As shown in FIG. 25 (F), the contents of the tables in the RAMs 135 and 136 are codes input via the selector 132 as input addresses, and codes C ₀ indicating colors to be formed during image formation by the printer in a frame sequential manner. , C ₁ is applied, as its output, having a function code and 8 bits of three bits. The three-bit function code is provided to the decoder 146 via the selector 137. The function code is, for example, a code for giving an instruction such as a character add-on or masking of a specific image area, as described later. The 8-bit data is, for example, density adjustment data of the image signal 612. 13
9, 143 and 145 are selectors whose selection states are switched in accordance with the outputs S0, S1, S2, S3 and S4 of the decoder, respectively, and 144 is a multiplier for multiplying the outputs of the selectors 143 and 145. Reference numeral 146 denotes the most significant bit MSB 621 of the 6-bit data input via the selector 132 (the area code is generated such that the MSB becomes "1" at the end of each area of the image as shown in FIG. 25 (E)). The decoder decodes three of the character signals indicated by the signals 613 and 614 shown in FIG. 2 and the function code input through the selector 137.

Next, the above-described area code will be described. The area code is a means for assigning a number, that is, an area code to each area when the area 148 is specified on the document 147 using the digitizer 16 or the like as shown in FIG. In this embodiment, the entire area of the original is set to an area code “0”, and points a and b in FIG.
For example, an area code “1”,
A rectangular area having points c and d as diagonal lines is set as area code “2”. Here, for example, AB shown in FIG.
When scanning a section, an area code is generated at the same time as scanning at the timing shown in the figure below. CD, E-
The same applies to the F section. As described above, the area code is generated simultaneously with the scanning of the document, and the area code is distinguished by the area code to realize different image processing and editing in real time for each area.

The above setting is performed by 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 n bits are set, 2 _n areas can be set.

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. The generation circuit 130 is a circuit that generates the area code described above in real time simultaneously with the operation of the original, and sets the coordinates and the area code of the area obtained by the area designating means such as the digitizer to programmatically generate the area code. Is to be generated. The details will be described below.

The RAMs 153 and 154 are memories each having a capacity of one main scanning line in a 7-bit 1-word configuration. This RAM is connected to the CPU via a CPU address bus 627 and a data bus 625. Reference numeral 149 generates a RAM address by counting Video CLK with an address counter. The counter 149 is reset by HSYNC, and the same address is selected every time a new line is scanned.
2 to RAM 153, 154. Therefore, the RAMs 153 and 154 read data from the start according to the reset. 155 is an interrupt generator which counts the number of HSYNCs input from the CPU by the CPU data bus 625 and the chip select 624 as a pre-programmed number.
The interrupt signal INT is generated in the PU, and the address counter 149 is activated by the toggle operation of the JK flip-flop 158.
Is also switched. 151,152,156
Is a selector according to the output of the flip-flop 158.
One of the RAMs 153 and 154 is selected by selecting one of the A and B inputs.

FIG. 25D is an explanatory diagram showing a data structure of the RAMs 153 and 154. As shown in the figure, MSB is divided into 1 bit and lower 6 bits, and the MSB indicates a change point between the designated area and the unspecified area as described above, and 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. FIG. 25D shows, for example, the RAM data when scanning between AB in the designated area 159 (area code "20") on the document 150 shown in FIG. 25E.
At this time, the entire area of the original is set to the area code “0”. Conversely, the set area is an example when the area code “20” is set. The RAMs 153 and 154 are sequentially read from the RAM set as described above from the address generated from the address counter 149, and an area code is generated. For example, in the case of scanning the section shown in FIG. 25 (E) A-B, immediately after the start of scanning, the MSB "1" lower order is output as the RAM output.
As for 6 bits, “0” (area code “0”) is read out, and as shown in FIG. 25 (C), a latch using the MSB627 as a latch signal.
The lower 6 bits are latched by 157, and an area code "0" is output. Also when the point a (O, P) is reached, the MSB "1" and the lower 6 bits "20" are read out as the RAM output, and latched in the same manner as described above to output the area code "20". Area code "2" until the address further advances and the next MSB becomes "1"
"0" is output, that is, the address r is read out, and the area code "20" is continuously output from the latch 157 until data is newly latched as described above.

When the scanning further proceeds and the main scanning in the Y direction ends, X
HSYNC is incremented by one in the direction, and HSYNC is counted by the interrupt generator 155. At this time, as described above, the address counter 14
9 is reset, and the read address is also restarted from 0. Further, since the area is rectangular, the same data, that is, one of the RAMs 153 and 154 can be continuously read out until scanning is completed in the section CD including the point b in FIG. Container 155
Next, the count number of the X-direction HSYNC, in this example (qo)
Is set, when the scanning from the section AB to the section CD is completed, the interrupt generator 155 outputs the interrupt signal I.
NT is generated, and at the same time, the RAM read by the selector 156 is switched by the toggle operation of the JK flip-flop 158 in FIG. 25 (C). As a result, the next area information programmed in advance is output from the RAM selected by the selector 156. In addition, the occurrence of the interrupt INT causes the CPU to generate another interrupt again from the coordinates of the area and the area code obtained by the above-described means to the interrupt generator 155 and the paused RAM, that is, the RAM not selected by the selector 156. Set the signal according to the specified area. Such setting is performed by the CPU by controlling the data bus 625 and the chip select signals C ₂ ′ and C ₃ ′. The configuration described above, ie, switching between two RAMs sequentially, and programming the idle RAM by the CPU to reduce the area code for the entire screen of the original with a small memory capacity
Can generate 626.

As described above, the area code 626 output from the area code generation circuit 130 shown in FIG.
132 is input together with the image signal, and edit processing for each area is performed based on the area code.

Although the area code generator 130 can generate an area code only for a rectangular area, the present embodiment is configured to be able to handle a non-rectangular area. 131 and 132 are provided for such a configuration.

Reference numeral 131 shown in FIG. 25 (A-1) denotes a register,
Connected to 8. An area code corresponding to the non-rectangular area is set in this register in advance.

At this time, as will be described later, when the non-rectangular area signal 615 is input from the image storage device 3, 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 Can be obtained.

As described above, the area code has 6 bits in this embodiment, and the MSB 621 1 bit has a decoder 146 and a selector 137.
And the other signals are input to the RAMs 135 and 136 in parallel.

The RAMs 135 and 136 are connected to the CPU by a CPU bus (collectively referred to as a data bus 625 and an address bus 627) 508 and have a programmable configuration.

FIG. 25 (F) shows the data structure of the RAMs 135 and 136. 133
Is a schematic diagram of the configuration of the RAM, and area code 4 is used as an address input
A total of 6 bits, ie, a bit and a color select signal 629, 2 bits, are input. At this time, the color select signals C ₀ , C ₁ , and C ₂ are changed from the LSB to ₂ bits C ₀ , C ₁ to select which of the four colors the image signal transmitted in a frame-sequential manner.
The access address is changed for each area code and color.

In the present embodiment, as will be described later, when an image is formed by the printer 2, the image is transferred in the order of M (magenta), C (cyan), Y (yellow), and Bk (black) for each color.
At this time, the type of color to be transferred is determined by the color select 629 signals C ₀ and C ₁ shown in FIG. 25A (the same signals as C ₀ and C ₁ shown in FIG. 10A). I have. FIG. 25 (F)
134 shows a detailed diagram of the data structure. 3 bits from MSB as shown
Has a function code, and by decoding this code, different image processing is performed according to the code. In this embodiment, six types of image editing can be performed for each area code or color by expressing the function code with 3 bits. The lower 8 bits store various parameters at the time of image processing and editing according to the function code.

The data selected from the area code and the color select signal is 3 bits from the MSB, that is, the function code is input to the selector 137 shown in FIG. 25 (A) 137, and 3bi output from the two RAMs by the area code MSB 621.
Switching of function code of t. On the other hand, the lower 8 bits of data are also selected and output by the selector 139 by the select signal S1 from the decoder 146.

The selected function code is input to the decoder 146 and combined with the character signal 622 and the area code MSBbit 621 to generate a control signal 623 for performing an editing process. Each control signal is used as a selector selection signal and editing is performed by changing the signal flow.
In this embodiment, the following six editing functions are realized by the control signal.

Area through This function is to output the image signal without performing any processing on the specified area. The input image signal passes through a negative / positive inversion circuit (described later) shown at 138 and is selected by S2.
It is selectively output from 143 and input to multiplier 144. On the other hand RAM
One of the data is selected from the selector 139 by S1 and further passes through a selector 145 determined by S3 and S4. The data is calculated and output by the multiplier 144 with the image signal. At this time, the density of the image is determined from the RAM data input to the multiplier 144, and if a different count is set for each color sent in a frame-sequential manner, the density and color balance can be varied independently for each area. .

That is, when the user sets the area using the operation panel and then sets the color balance of the area, the CPU writes the set value to the RAM 135 or the RAM 136 via the bus 508. Further, the B input of the selector 145 may be selected and multiplied by the image signal 612 and the multiplier 144.

Area masking This is a function to output an image uniformly painted in any other color over the entire specified area. For example, while scanning an area in which this function is set, data in the RAM is selected instead of an image signal by S2 and input to the multiplier 144. On the other hand, the coefficient selects the register 142 from the control signals S3 and S4 and is connected to the CPU via a bus (not shown), and an appropriate coefficient such as "1" is stored in advance by the CPU. The operation is performed by the multiplier 144 and output.

Insertion of character in area (1) For example, as shown in FIG.
In this mode, characters such as 160 shown in 9 are inserted.
For example, a character date is stored in a bit map memory or the like in advance as shown at 161. The binary data of the character is scanned and read out from the memory at the timing shown in FIG.
This signal is input as a character signal shown in FIG. 25 (A) 622, and the selector 143 is switched. That is, when the character signal 622 is High, the selector 143 is connected to the RAM 135 or
The decoder 146 performs the insertion by outputting the data S0 to S4 that select the data 136 and select the image signal when the data is low. Further, S3 and S4 change together with the character signal, and the coefficient of the multiplier 144 selects the register 140 when the character signal 622 is high. Again, as mentioned earlier,
It is connected to the bus and sets an appropriate coefficient in advance. Normally, 1 is set in the register 140. In particular, by changing the coefficient set in the register 140, the density of the inserted character can be freely changed.

Insertion of characters in area (2) As shown in FIG. 25 (H), a function of masking the inside of a specified area with a certain specified color and inserting characters in the same area with another specified color as described above. is there. During the scanning of the designated area, the selector 143 selects the data in the RAM as described above. At this time, as described above, the selector 139 is switched from the character signal obtained from the bit map memory shown in FIG. That is, if it is not a character, the data of RAM 135 is output.
This is implemented by selecting 36. It should be noted that, for example, density data of characters in the area is written in the RAM 136 and density data of characters other than the characters in the area is written via the CPU bus 508 in advance.

In the same manner as described above, the registers 142 and 140 are selectively output for the coefficient together with the character signal. The operation is performed by the multiplier 144 and output.

That is, since the registers 140 and 142 are separately provided, the density of the character part and the density other than the character part can be set independently.

Negative / Positive Inversion in Area This function is to output only the image in the area after negative / positive inversion, and switch the negative / positive inversion circuit 138 by the control signal S0. The output from 138 is output with the same settings as the through function.

Negative / Positive Inverted Character Insertion in Area A combination of the above-described character insertion function in area (1) and the negative / positive inversion in area described above is a function of inserting characters into an image of negative / positive inversion in area. Since the character inserting means is the same as the above-mentioned means, the description is omitted.

Are shown. Also, the left side shown as “input” in the figure is the input of the decoder 146, and the right side shown as “output” is the output S0 to S4 of the decoder 146.

The select signals of the selectors 4254R, 4254G, and 4254B are
Although not shown, it is controlled by the CPU 4360 and is programmable.

As described above, for example, when a halftone image or the like is read from the color reader 1, the filter circuit 9500 averages images to prevent image deterioration due to moire.

At this time, the system controller 4210 also performs a trimming process and a scaling process at the same time.

Further, the FIFO memories 4050AR, 4050AG, and 4050AB absorb the difference in clock between the color reader 1 and the image storage device 3.

These processes of the present embodiment are shown in the circuit diagrams of FIGS. 27 and 29,
This will be described below with reference to the timing chart of FIG.

The filter 95 from the selector 4250 shown in FIG.
Prior to the data transfer to the FIFO memories 4050AR, 4050AG, and 4050AB via 00, the effective area in the main scanning direction of the area specified by the digitizer 16 is written to the comparators 4232 and 4233 shown in FIG. FIG. 29 shows the configuration of the system controller 4210 and the FIs in the memories A to M.
FIG. 3 is a diagram illustrating a configuration of an FO memory.

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

Further, the sub-scanning direction of the area designated by the digitizer 16 is controlled by controlling the selector 4213 to select the CPU bus 9610 side to be valid, and “0” data is written in the valid area of the area designated by the RAM 4212, Write "1" data to the invalid area.

In the scaling process in the main scanning direction, the scaling factor is set to the rate multiplier 4234 shown in FIG. 29 via the CPU bus 9610. Further, the scaling process in the sub-scanning direction can be performed by data written to the RAM 4212.

FIG. 30 is a timing chart when the trimming process is performed. As described above, when only the area designated by the digitizer 16 is stored in the memory (trimming processing), the trimming position in the main scanning direction is set in the comparators 4232 and 4233 shown in FIG. The position is such that the selector 4213 is set to the CPU bow 9610 side, and the CPU writes the data to the RAM 4212 ((example) trimming area in main scanning 1).
000 to 3047, and sub-scanning 1000 to 5095). That is, RAM
Reference numeral 4212 denotes “1” or “0” in an area corresponding to each address output from the counter 4214 input through the selector.
Is written by the CPU. As will be described later, “1” is data for inhibiting the reading of the memories 4050AR, AG, AB, and “0” is data for performing reading.

The trimming section signal 9100 in the main scanning direction is
The counter 4230 operates in synchronization with the ▲ ▼ 9452 from 9420S and CLKIN9456, and this counter output 9103 becomes 10
When it becomes 00, the output of the comparator 4232 becomes 1,
The output Q of the flip-flop 4235 becomes 1. Subsequently, when the counter output 9103 becomes 3047, the output of the comparator 4233 becomes 1, and the output of the flip-flop 4235 becomes 1 to 0.
Becomes In the timing chart of FIG. 30, the output of the rate multiplier 4234 is 1 because the unity magnification process is performed. The signal is input to the FIFO memories 4050AR, AG, AB by the trimming section signal 9100, and the addresses 1000 to 3047 of the color image information are written to the FIFO memories 4050AR, AG, AB.

In addition, the comparator 4231 outputs a signal delayed by 1 pixel with respect to ▲ 9542 from the control line 9420S.
9107 is output. In this way, the ▲ input and ▲ input of the FIFO memories 4050AR, AG, AB are input to the FIFO memories 4050AR, AG, AB by providing a phase difference. Absorb the difference between the periods of CLKIN9456 and CLK9453 from the control line 9420S.

Next, trimming in the sub-scanning direction is performed by first controlling the selector 4213 shown in FIG. 29 to select and enable the counter 4214 side, and from the control line 9420S to ▲ ▼ 9455,
▲ ▼ Transfer the section signal 9104 synchronized with 9452 to RAM4
Output from 212. Section signal 9104 is flip-flop 421
Synchronize with the signal 9107 by 1 and input to the read enable of the FIFO memories 4050AR, AG, AB. That is, FIFO memory 4050
The image information stored in AR, AG, AB is a trimming signal 9101
Only when A is "0" is output (n 'to m').

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

The signal 9101 described above has six independent systems for the memories A to M, and the signal 9100 is independent of only the memory M and has two systems in total.

In the above description, only the trimming process has been described, but the scaling process can be performed simultaneously with the trimming. To change the magnification in the main scanning direction, use the rate multiplier 4234 to set the magnification to CP.
Set via U bus 9610. In the sub-scanning, a scaling process can be performed by data to be written to the RAM 4212.

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

FIG. 31 is a diagram showing an example of a timing chart when the image data from the selectors 4254R, G, B are scaled down by 50% and transferred to the FIFO memories 4050AR, AG, AB.

The set value of 50% reduction is set to the rate multiplier 4234 of FIG. 29 via the CPU bus 9610. At this time, the output 9106 of the rate multiplier has a waveform in which “0” and “1” are repeated for each pixel in the main scanning direction as shown in FIG. A logical product signal 9100 of this signal 9106 and the section signal 9105 generated by the comparators 4232 and 4233 controls the write enable to the FIFO memories 4050AR, AG and AB to reduce the size.

In the sub-scanning, as shown in FIG. 31, the write data to the RAM 4212 (read enable signal to the FIFO memories 4050AR, AG, AB) is set to "1" (read-out prohibited) in the image data valid area. Only the image data reduced by 50% is sent to the image memories 4060AR, AG, AB. In the case of FIG. 31, the read enable signal 9101 is reduced by 50% by repeating "1" and "0" data alternately.

In other words, trimming and scaling in the main scanning direction
Control the write enable of FIFO memory 4050AR, AG, AB,
Trimming and scaling in the sub-scanning direction are performed in FIFO memory 40.
Controls the read enable of 50AR, AG, AB.

Next, from the FIFO memory 4050AR, 4050AG, 4050AB, the memory 40
The transfer of the image data to the 60AR, 4060AG, and 4060AB is performed by the counter control 9141A, the counters 4080A-0 to 3, and the control line 9101A shown in FIG. 27 (C).

Note that 9101A is the output of the flip-flop 4211 shown in FIG. 29 and read enable ▲ ▼ of the FIFO 4050R, G, B,
Write enable of memories 4060A-R and B shown in FIG.
It is used as ▼.

The counter control 9141A shown in FIG. 27 (C) is a counter for generating an address for the memories 4060A-R, G, B.
This circuit controls the 4080A-0 to 4080A-3 and has the following three main functions in response to commands from the CPU.

1. CPU read / write mode → Data at any address can be referenced by the CPU.

2. Read mode → The stored image data is read out by the control signal of the system controller, and transferred to the color reader 1 to obtain a print output.

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

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

The control line 9101A is the read enable signal of the FIFO memory, 4050AR, AG, AB, and the counter control 91
Input to 41A to control the counter. Further memory 406
It is also a write enable signal of 0AR, AG, AB.

When the counter control 9141A is in the light mode,
The input control signal 9101A is used as a counter enable signal of the counters 4080A-0 to 3-0A-3. Note that the counter control includes a case where a counter corresponding to a CPU command is selected and a case where all counters are selected. 91
40A enables the counter enable signals 4080A-0 to 403A-0 to select a counter to be operated when the control line 9101 which is a counter control signal is "0". At this time FIF
The image data read from the O memories 4050AR, AG, AB is input to the memories 4060AR, AG, AB and stored at the addresses indicated by the respective counters.

At this time, for example, if the counter 4080A-0 is selected, the enable of the counter 4080A-0 is "0", and the signal 9120A-0 counted up in synchronization with the clock 9945A is set.
Is output from the counter 4080A-0, passed through the selector 4070A, and input to the address line 9110 of the memories 4060AR, AG, AB.

At this time, the write enable ▲ ▼ 9101A of the memories 4060AR, AG, AB is also “0”.
Image data 9090R, G, B input to R, G, B are stored.

Since the memory capacity in this embodiment is 1 Mbyte for each color, the image data in the reading area in FIG.
By reducing the size by 50%, the read image data is converted into data having the maximum capacity of the memory of the image storage device 3 and stored.

Further, in the above embodiment, the CPU 4360 calculates an effective area from the information of the area specified by the digitizer 16 of the A3 document,
Data corresponding to the comparators 4231 to 4233, the rate multiplier 4234 and the RAM 4212 shown in FIG. 29 are set.

In the present embodiment, since the data capacity of the read image is larger than the provided image memory capacity, a reduction process is performed, the data is converted into a storable capacity, and then stored in the image memory. But,
If the data capacity of the read image is smaller than the provided image memory capacity, the trimming information data is set in the comparators 4232 and 4233 that control writing to the memory in the area specified by the digitizer 16, and the rate multiplier 4234 is set. Sets the same magnification. In the write data to the RAM 4212, the image effective area is all set to “0”, and the others are set to “1”, and are set to the same magnification.

Further, in order to store the read image in the memory while maintaining the aspect ratio (vertical / horizontal ratio), the CPU 4360 first obtains the number of effective pixels “x” from the area information sent from the digitizer 16. Next, z is obtained from the maximum capacity “y” of the image storage memory by the following equation.

As a result, (1) When z ≧ 100, the setting of the rate multiplier 4234 is such that the entire effective image area is set to “0” in the 100% RAM 4212 and stored at the same magnification.

(2) When z <100, the setting of the rate multiplier 4234 and the RAM 4212 are both reduced by z%, and stored in the maximum capacity of the memory while maintaining the aspect ratio.

Also in this case, as the data to be written to the RAM 4212, data of “1” and “0” may be written in a timely manner corresponding to the reduction rate “z”.

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

In addition, the settings described above are stored in the image storage memory (memory
A, B, C, D) and the display (memory M) shown in FIG. 27 (E) can be set independently. When storing images, the same image can be simultaneously stored in different memories at different magnifications, for example. As described above, the data can be stored in the memories A, B, C, D and the memory M.

<Description of Memory E> The memory E in FIG. 27A will be described. No.
Fig. 27 (D-1) shows a schematic diagram of the internal configuration. Memory E
Is a binary image memory (hereinafter referred to as bitmap memory)
The operation is similar to that of the memory A described in the previous section.

Among the image data read from the color reader, the image data to be written to the bit map memory E passes through the selector 4250 and the filter 9500 in the same manner as described in the preceding section, and is stored in the FIFO 4050E-R shown in FIG. 27 (D-1) in the memory E. Written. In such a case, writing is controlled by the write enable 9100 as described with reference to FIG. At this time, in the embodiment, only the R signal is used as an image signal, but any other signal may be used as long as it is represented by a luminance signal. For example, a G signal or a signal obtained by taking a weighted average of R, G, and B at a predetermined ratio may be used. The image data written in the FIFO 4050E-R is read out by the control signal 9101E in the same manner as described in the previous section,
The data is binarized by a binarization circuit indicated by -R and sequentially written to the memory. At this time, black becomes “1” and white becomes “0”. The CPU writes a predetermined value to the register 4053 via the bus as the binarization threshold. For example, as shown in FIG. 27 (D-2), a heart-shaped document A having a certain density on a white background is prepared, and an area B is designated as a dotted line in the figure. By reading this area into the bitmap memory E, a binary image of "0" and "1" 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 read by the CPU by the system controller 4210 in the same manner as described in FIG. 29. The writing position is controlled. By sequentially reading this data as indicated by the arrow, a non-short region signal as indicated by F in FIG. 27 (D-2) is output to the signal line 4072 and the selector
Used as 4071 select signal. One input of the selector 4071 is provided with an 8-bit capacity register 4074 connected to the CPU bus so that a predetermined output density value is set in advance. For example, 80H is input. Therefore, when the signal 4072 is "1", 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.

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

The above-mentioned 4171 and 4172 correspond to those in FIG. 27 (B). Are input to the video interface 201 shown in FIG.

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

<Image Storage from SV Recording / Reproducing Apparatus 31> The system of the present embodiment uses an SV recording / reproducing apparatus as shown in FIG.
It is also possible to store the video image from 31 in the image storage device 3 and output it to the monitor television 32 or the color printer 2. The image processing device 3 also handles the input image.

Hereinafter, a description will be given of how a video image from the SV recording / reproducing device 31 is loaded into the image storage device 3.

First, the control of taking in the video image from the SV recording / reproducing device 31 into the image storage device 3 will be described with reference to FIGS.
This will be described below with reference to block diagrams of the image storage device 3 of -2) and (B).

FIG. 27 (A-2) is a diagram for describing the internal configuration of the analog interface 4530.

The video image from the SV recorder / player 31 is input to the video input terminal 45
The signal is input as an NTSC composite signal 9000 via 00, and is separated by a decoder 4000 into four signals, 9015R, G, B, and S, which are a separate R, G, B signal and a composite SYNC signal.

In addition, the decoder 4000 outputs the Y signal from the video input terminal 4510.
The (luminance) / C (chroma) signal 9010 is decoded in the same manner as described above. Each signal of 9020R, 9020G, 9020B, 9020S to the selector 4010 is a separate R, G, B signal and composite SYNC signal.

Also, the composite SY selected by the selector 4010
The NC signal 9050S is input to the TBC / HV separation circuit 4030,
The clock signal 9060C, the horizontal synchronization signal 9060H, and the vertical synchronization signal 9060V are further generated from the composite SYNC signal 9050S by the / HV separation circuit 4030, and the image enable signal 9060EN shown in FIG. The enable signal EN is a signal indicating a certain image area.

As described above, the selector 4250 sets the image source to an image from the color reader 1, an image from various video devices (in this embodiment, an SV player is assumed), or a film scanner.
This is a selector for selecting and outputting the image from. The specific operation will be described with reference to FIGS. 28 (B) and (C).

For example, when selecting an image on the video device side, the control signal
SELECT-A and SLECT-B are set to 0 and tristate buffers 4353R, G, B, HS, VS, CK, EN and 4252R, G, B, HS, VS, C
By making use of only K and EN, setting SELECT-C, D, E, F, to 1 and setting all other trislat buffers to high impedance, image signals 9051R, G, B from video equipment
And synchronization signal 9051S are coupled to 9420R, G, B, 9420S, respectively.

The same applies when inputting image data from another device. Further, the present embodiment is characterized in that a connection buffer with the color reader 1 or the film scanner 34 is used in the selector 4250 in order to use a bidirectional communication line.

In the 9051 output from the TBC / HV separation circuit 4030 of the present embodiment, for example, in the case of the NTSC standard, the TVCLK9060C signal is 12.27 MHz.
, 9060H signal is a signal having a pulse width of 63.5 μS, and 9069060V signal is a signal having a pulse width of 16.7 mS.

When switching 50, the CPU switches each switch 4 of the filter 9500.
254R, G, B are switched to the upper side in FIG. 28 (A). Therefore, any one of the memories A, B, C, D, E, and M is input without substantially applying a filter. When capturing an image from a reader, there is an image in which moire occurs, such as an image of a halftone dot.
4254R, G and B are switched to the lower side. Next, description will be made again with reference to FIG.

▼ Reset by 9060H signal, TVC starts from “0”
Data 9060R, 9060G, 9060B are written in synchronization with the LK9060C signal. The writing to the FIFO memories 4050AR, 4050AG, 4050AB is output from the system controller 4210.
Performed when signal 9100 is energized.

This FIFO memory 4050AR, 4 by this ▲ ▼ signal 9100
The details of the write control of 050AG and 4050AB will be described below.

In the case of the SV recording / reproducing apparatus 31 according to the present embodiment, for example, in the case of the NTSC standard, the pixel capacity obtained by digitizing the video image from the SV recording / reproducing apparatus 31 is a screen capacity of 640 pixels (H) × 480 pixels (V). Therefore, first, the CPU 4360 of the image storage device 3 writes the set value to the comparators 4332 and 4233 so as to have 640 pixels in the main scanning direction. Next, the input of the selector 4213 is input to the CPU bus 961.
On the 0 side, "0" for 480 pixels in the sub-scanning direction is written into the RAM 4213.

Also, 100% data is set in the rate multiplier 4234 for setting the magnification in the main scanning direction.

When the image information of the SV recording / reproducing apparatus 31 is stored in the memories 4060AR, AG, AB, the system controller 4210 outputs ▲ ▼ 9060V, ▲ output from the TBC / HV separation circuit 4030.
▼ 9060H, TVCLK9060C are shown in Fig.29 ▲
Connected to ▼ 9455, ▲ ▼ 9452, CLKIN9456.

As described above, by setting the image control signal to the interface of the SV recording / reproducing apparatus, the A / D converters 4020R and 402
The data for one main scan of the video image of 9051R, 9051G, 9051B, which is the output signal from 0G, 4020B, is input to the filter circuit 9500, and the output signals 9420R, G, B are stored in the FIFO memories 4050AR, 4050.
It is stored in 50AG and 4050AB at the same magnification.

The memory capacity of this embodiment is, for example, per one memory A, the above-mentioned NTSC standard video still image (640 pixels (H) × 480 pixels).
Pixels (V)) can be stored up to four.
When stored at the same size in the 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 detached from the main unit, and can be expanded. When expanded, high-band specifications (768 pixels (H) x 480 pixels (V)) Are stored in a similar manner. The details will be described below.

In this apparatus, when the power is turned on, the CPU 4360 starts a program for detecting the capacity of each memory, detects the capacity of each memory, and stores the result in a work register (not shown) in the CPU 4360, as shown in FIG. FIG. 32 (B),
(C) is an explanatory diagram illustrating an algorithm of the above-described program.

For example, for simplicity, if 4060A-R in the memory A is represented in a schematic diagram in association with an address as shown in the figure, the hatched portion is an additional portion, and when no memory is provided at the corresponding address aH, Cannot store data even when accessed by the CPU 4360.

On the other hand, after the memory in the area corresponding to the shaded area is added, the memory capacity per image is increased so as to be compatible with the high band specification, and the memory cell also exists at the address aH. Data access by the CPU 4360 is also possible.

Here, the CPU 4360 writes b bytes of predetermined data from a certain address aH, reads data from the address aH, and compares the read data with the written data to detect the memory capacity. FIG. 32 (C) shows a flowchart of this operation. That is, when the memory is not added, the terminal of the address aH is opened, so that the CPU 4360
When the data is read out, since the high level is continuously output, the capacity of the memory can be detected by the above operation. As described above, the result of detecting the memory capacity is
The sampling clock of the A / D converter 4020R, G, B is changed by the CPU 4360 controlling the OSC4031 based on this data as shown in FIG. 27 (A-1). The sampling clock is switched between a high band input and a low band input in accordance with the memory capacity.

In this embodiment, the SV control connector 4420
By connecting the SV player (reproducer) 31, commands can be exchanged between the SV player 31 and the CPU 4360 via the SV controller 4420. At this time, the SV player (reproducer) detects whether the video image being reproduced is an image recorded in the high band mode or an image recorded in the low band mode. Such a detecting means is well known and will not be particularly described. Next, the SV player sends the corresponding command to the CPU 4360 via the SV controller 4420, so that the CPU 4360 can control the sampling clock based on the data on the remaining amount of the image memory stored in the work register and the command. Yes, it will be possible to respond more precisely. For example, when the memory corresponds to the high band and the video is the high band, the sampling clock becomes the high band. Also, when the memory is low band compatible or the video equipment is low band, the sampling clock is low band compatible.

In addition, the CPU 4360 operates according to the image data stored in the memory.
By adjusting the gains of the video amplifiers 4011R, G, and B optimally and storing them again in the memory, the best images can be stored (hereinafter referred to as AGC (auto gain control)). The details will be described below. FIG. 32 (D) shows an algorithm flow chart. The operation is performed in the H diagram of FIG. 47 or the C diagram of FIG. 50 (A).
It works by pressing the AGC key.

When storing a video image, first, for example, the amplifiers 4011R, G, and B that can control the gain in eight stages are set to the minimum gain (S1). After the setting, the video image is stored in the memory (S2), and the following check is performed by the CPU (S3). The check in S3 is that if the image data is, for example, 8 bits, the data of the stored image is the maximum value.
A check is made to see if FF _H (the value of the highest luminance in this embodiment) has been reached. In this method, a check is performed on the entire image area or a part of the area.

In the present embodiment, a central partial area of the stored image is used as a representative of the entire area. This can reduce the check time.

These checks are performed for each of R, G, and B of the stored image. In S4, any one of R, G, and B is, for example, 8
If it is bit image data, check if it is FF _H
If there is no pixel of the FF _H are amplifiers 4011R, store G, again the memory raised one step the gain of B, is performed by turning chestnut processing from S2. If FF _H is found, the processing ends.

By performing the above-described processing, it is possible to always store an image 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.
A comparator is added to the output of the A / D converters 4020R, G, B shown in FIG. 27 (A-1), and the video amplifiers 4011R, G,
It is also possible by changing the amplifier gain of B.

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

 The color balance function will be described later in detail.

<Storage of image from SV recording / reproducing apparatus 31 at SV index> At the time of SV index, 25 images from the SV recording / reproducing apparatus 31 are stored in the memory.

The SV image information 9421R, G, B from the analog I / F 4530 in FIG. 27 (A) is 320 × 240 at the time of indexing.
Pixels are stored as image units on one memory board of the memory A / D for 25 planes.

Image storage at the time of such SV indexing is performed by reducing the size of a normal image from a video device from 640 × 480 pixels to 1/2 and storing it in a memory at 320 × 240 pixels. This 320 × 240
By setting the pixel size to one pixel, 25 screens can be stored in one memory board having 2M pixels.

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

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

The reduction of the SV image information is omitted because it is performed by controlling the writing and reading of the FIFO similarly to the image storage from the color reader 1 described above.

After storing the image information of one screen from the SV recording / reproducing apparatus 31, the CPU (4360 in FIG. 27 (B)) in the image storage device 31 sends a track-up signal to the SV recording / reproducing apparatus 31 via the SV controller 4400.

The SV recorder / reproducer 31 uses this signal to respond to the SV jacket.
The track being accessed by the reproduction head is moved to the inner circumference by one track. Next, the image signal recorded on the track making the access is reproduced and sent to the image storage device 3. The image storage device 3 moves the head again by one track in the same manner as the above operation, and stores the image signal stored in the next track in the memory.

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

<Image display from SV reproducer 31 during SV index> Image information from SV reproducer 31 during SV index is sequentially changed to the SV reproducer, the track being accessed by the reproduction head with respect to the SV jacket. Typically, the information is displayed on the monitor television 32 while being tracked. This display is shown in FIG. 33 (C).

The SV image information 9421R, G, and B from the analog I / F 4350 in FIG. 27A are stored in the memory M for 128 screens with 128 × 96 pixels as one single image unit.

For the monitor display in the SV index, the size of a normal image from a video device, 640 × 480 pixels, is reduced to 1/5 and stored in a memory at 128 × 96 pixels.

The reduction of the SV image information is performed by controlling the writing / reading of the FIFO memory in the same manner as the image storage from the color reader 1 described above.

After storing the image information of one screen from the SV reproducer 31 in the memory M, the CPU in the image storage device 31 (436 in FIG. 27B)
0) sends a track-up signal to the SV recorder / player 31 via the SV controller 4400.

The SV recorder / reproducer 31 changes the access position of the reproduction head to the track of the SV jacket based on this signal, and then sends the track image to the image storage device.

The image storage device 3 stores the next image in the memory M in the same manner as described above.

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

The image information stored in the memory M is a LUT (FIG. 27 (E)
4420R, G, B), are converted into analog signals by the D / A converters 4430R, G, B, and the index image is displayed on the monitor television 32.

<Read processing from image storage device> Next, the memories 4060AR, 4 of the image storage device 3 described above
A process of reading image data from 060AG and 4060AB will be described.

The instruction input when the image output from the memory is formed by the color printer 2 is mainly performed by the digitizer 16 and the operation unit 20 shown in FIG.

For example, when an area where an image is to be formed is designated by a digitizer as shown in FIG. 37, the color reader 1 sends the position coordinates to the CPU 4360 of the image storage device 3 via the control line 9460 connected to the connector 4550. Such position coordinates are output, for example, as 8-bit data.

The CPU 4360 uses the area signal generator 4210-2 (similar to that shown in FIG. 12 (d)) in the system controller 4210 shown in FIG. Are programmed to obtain the desired image output. Specifically, data corresponding to the coordinate information is set in the RAMs 555 and 556 shown in FIG. 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 ends, the image storage device 3 waits for a command from the color reader 1, and the image formation is started by pressing a copy start button here.

When the start button is pressed, the color reader 1 sends the command to the CPU 4360 of the image storage device 3 via the signal line 4550, and the CPU 4360 which receives the command switches the selector 4250 instantaneously. In FIGS. 28 (B) and 28 (C), the setting for sending an image from the image storage device 3 to the color reader 1 is as follows. All buffers are high impedance. Further, the CPU 4360 sets the counter controller of the memory storing the desired image to the read mode.

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

First, an embodiment in which an image is formed in accordance with the size of a recording sheet, 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 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. In this case, A4 size recording paper is set in the upper part, and A3 size recording paper is set in the lower part. The selection of the recording paper is input by the liquid crystal touch panel of the scanning unit 20. The following description is for the case where a plurality of images are formed on A4 size recording paper.

First, prior to image formation, by inputting read image data from the color reader 1, the film scanner 34 or the SV recording / reproducing apparatus to the image storage device 3, the image memories 4060AR, 4060AG, and 4060AB, which will be described later, As shown in FIG. 5A, a total of 16 image data of “image 0” to “image 15” are stored.

 Next, press the start key from the operation unit.

As a result, the CPU 22 shown in FIG. 2 detects this key input 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).

Details of the above image forming processing in this embodiment will be described below with reference to the block diagram of FIG. 27 and the timing chart shown in FIG.

ITOP sent from the color printer 2 to the color reader 1 via the printer interface 56 shown in FIG.
The signal 511 is input to the video interface 201 in the video processing unit 12, and is sent from this to the image storage device 3. The image storage device 3 starts the image forming process in response to the ITOP signal 551. Then, each image sent to the image storage device 3 is stored in the image storage device 3 as shown in FIG.
An image is read from the memory ABCD or the like under the control of the system controller 4210 shown in FIG.

Control signals 9102-0 to 9302-3 output from the area signal generator (FIG. 27 (F)) in the system controller 4210.
Is a counter enable signal, for example, a memory A
Is read from the counter control 9141A. The counter control 9141A enables the counter based on the input control signal, and controls the select signal 9140A of the selector 4070A. At this time, the counter control 9141A simultaneously outputs the read enable signal 9103A, and this signal is output to the FIFO 4140-0 of the next stage.
~ 3 write enable signals.

With this access, the image data stored in each of the memories 4060AR, 4060AG, 4060AB is read out, and the read-out image signals 9160AR, 9160AG, 9160AB from each memory are stored in a lookup table (LUT) 4110AR shown in FIG. 27 (C). , 4110AG, 4110A
B, where logarithmic conversion is performed to match the relative luminous efficiency characteristics of the human eye. At this time, 4111A is an LUT selection signal sent from the area signal generator 4210, and the LUT can be arbitrarily selected for each area. In this embodiment, 16 types of LUTs can be selected. 9200A conversion data from each LUT
R, 9200AG, 9200AB is masking / black extraction / UCR circuit 4120A
Is input to The masking / black extraction / UCR circuit 4120A performs color correction of the color image signal of the image storage device 3 and performs UCR / black extraction when recording black.

And these continuous masking /
The image signal 9210 from the black extraction / LCR circuit 4120A is input to each of the FIFO memories 4140-0 to 4140-3 by the selector 4130 shown in FIG. 27B based on the select signal 9230 output from the area signal generator. You. As a result, the images arranged sequentially as shown in FIG. 33 (A) can be processed in parallel by the operation of the FIFOs 4140-0 to 3140-3.

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

In FIG. 27 (B), 9240-0 to 3 are FIFO-read before performing a write operation with a reset write signal to FIFO 4140-0 to 3140-3.
Reset the address of 9320-0 to 3320 are enable signals for the enlargement interpolation circuit, and 9340 selects the enlargement interpolation circuit to be used by the select signal of the selector 4190. Each is output from the area signal generator, and up to four can be independently expanded for each area.

For example, the enlargement interpolation circuit by the enable signal 9320-0
When 4150-0 is enabled, the enlargement interpolation circuit 4150-0
Outputs a read enable signal 9280-0 to the FIFO 4140-0, receives image data from the FIFO, and performs enlargement processing. In this embodiment, a primary interpolation method is used. Similarly, when the other enlargement interpolation circuits are enabled, the read enable signal is sent to the FIFO and the data of the FIFO is read. FIG. 35 shows a timing chart.

At this point, as described above, the image data sequentially read from the memory is processed in parallel, finally the layout of the image is completed by the selector 4190, and the image data processed in parallel so far is serialized again. Image data signal. Image signal 9330 converted into serial image data by selector 4190 is subjected to edge enhancement and smoothing (smoothing) processing by edge filter circuit 4180. Then, the signal passes through the LUT 4200 and is input to the selector 4230 via the signal line 9380.

The selector 4230 stores the data of the bitmap memory described above. And image data from the memory. Details of the two switching operations will be described later with reference to FIG.

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

Hereinafter, when the formation of all the image data of “image 0” to “image 3” is completed, next, “image 4” to “image 7”, “image 8” to “image 11”, and “image 12” to “image 12” Images are sequentially formed in the order of “Image 15”, and 16 images “Image 0” to “Image 15” shown in FIG. 34 (A) are formed.

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

Further, in the case of an image from the SV recording / reproducing apparatus 31, an image of SV floppy can be continuously printed out, and has a function as an index print.

When performing this SV index printing, there are many cases where the color balance is different depending on the function of the SV player or the environment when shooting with the SV camera, that is, the color temperature is different, so this color balance is corrected. For this reason, the present embodiment has a function of automatically having a color balance. This color balance function is
It functions by pressing the AGC key in the figure H of the figure or the figure C of the figure 50 (a). The details will be described below.

From the image data of a plurality of screens stored in the memory, N pixels (1 ≦ N ≦ the total number of pixels) are respectively used.
The CPU 4360 processes data while taking in a total of 256 pixels into the CPU 4360, and based on the processing result, the CPU 4360 selects or creates an optimal correction table from the ROM in the CPU 4360 (not shown) and creates a lookup table 4110A-R, G, B Set to.
For example, in the case of selecting and setting, one of the curves indicated by to in FIG.
G and B are set by selecting one from among FIG.

As will be described later, this can also correct the monitor display image.

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

 Next, selection of a correction table will be described.

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

First, the CPU 7 sequentially fetches the image data N in the memory 3 (step S1), and obtains R, G, B signal values Ri, Gi, Bi.
(1.ltoreq.i.ltoreq.N in the i-th pixel data) The signal value is not saturated (for example, when the image data is 8 bits, if white is 255 and black is 0, it is not saturated). Is not 255) Extract pixel data. This is R
This is because if any one of i, Gi, and Bi is saturated, the data is shifted from the color balance of the original data, so that the color balance cannot be accurately determined.

The sequential capture of the image data N in the memory 3 is performed as follows, for example. That is, when data of a plurality of screens, for example, 20 screens, is taken in the memory, the processing is performed by sequentially sampling the color image data from each of the 20 screens. That is, in this embodiment, even if there is a screen in which the hue is deviated among the plurality of screens, the data is sampled on average from a plurality of screens in the memory 3 without being affected by the screen in which the hue is deviated. Color balance correction can be averaged.

The minimum value among Ri, Gi, and Bi among the acquired signal values is N
R, G, B components of the largest pixel among the pixels are RMAX,
GMAX and BMAX are set (step S2). The minimum value among Ri, Gi, and Bi represents the feature of the pixel data. That is, the minimum value of Ri, Gi, and Bi for a reddish pixel is Ri. Ri, Gi, Bi
The pixel having the largest minimum value among the pixels is a pixel having the lightest component representing the characteristic of the pixel data. Therefore, RM
AX, GMAX, and BMAX are considered to be the Ri, Gi, and Bi components of the pixel representing white in the SV image. The maximum value of RMAX, GMAX, BMAX is DMAX,
The difference between the maximum value and the minimum value is defined as DSA (step S3). DMA
X is the lightest component among the R, G, and B components of the pixel considered to be white. If DSA = 0, the color balance (white balance) of the pixel considered to be white is obtained, but when DSA ≠ 0, a correction such that DSA = 0 is required.

Next, average values AVER, AVEG, and AVEB of Ri, Gi, and Bi of the N image data are obtained. Then, the maximum value of AVER, AVEG, and AVEB is set to AVEMAX, and the difference between the maximum value and the minimum value is set to AVESA (step S4). AVEMAX is the average pixel data R, G, B
It is the lightest component among the components. If AVESA = 0, the average density of the SV image becomes achromatic, indicating that the color balance is maintained to some extent. This is an application of the Evans's theorem used when printing a transmission film with silver halide, to an SV image. If AVESA = 0, the color balance is out of alignment, so AVESA = 0
Needs to be corrected.

The maximum value DMAX of each component of the white level,
The maximum value AVEMAX among the average values of Ri, Gi, and Bi, the chromaticity DSA of the white level, and the chromaticity A of the average value of all image data
The membership functions for VESA are 1-a, 1-b, 1-c, and 1-d shown in FIG. 35 (D). Membership functions 1-a, 1-b, 1-c and 1-d are stored in the ROM 13 as tables, respectively.
Is registered in advance.

The CPU 7 determines the grade of the white level dependency WDMAX of the brightness correction from the maximum white level value DMAX according to 1-a (step S5). If the value of the maximum value DMAX of the white level is large, it means that the brightness correction is performed with emphasis on the white level rather than the average value of all the image data. In other words, a large DMAX means that the pixel determined to represent white was actually a pixel close to white. Conversely, a small DMAX means that the pixel determined to represent white was actually a pixel far from white. Therefore, the white level extracted from the N image data cannot be emphasized.

Next, according to 1-b, the grade of the brightness correction degree WAVE is obtained from the average maximum value AVEMAX (step S6). Average maximum
As the value of AVEMAX becomes smaller or larger than the center, it means that the degree of performing the brightness correction becomes smaller. That is, if the input image is originally dark,
If the correction for brightening the image is performed, the characteristics of the input image are changed more than necessary. Thus, in this embodiment, AVEMAX is smaller gradually brightness correction degree WAVE if: D ₁ of the step S6. on the other hand,
If the input image is originally bright, because it is not further necessary to brighten, AVEMAX is gradually reduced brightness correction degree WAVE For D ₂ or more.

Further, the grade of the white level dependency WDSA of the color balance correction is obtained from the chromaticity DSA of the white level according to 1-c (step S7). If the chromatic chromaticity DSA value of the white level increases, the intention of the white level may not be white, so the data used for color balance correction emphasizes the average value of all image data over the white level It means to do. Next, according to 1-d, the grade of the color balance correction degree WSA is obtained from the chromaticity AVESA of the average value of all the image data (step S8). When the value of the average chromaticity AVESA increases, the image may originally deviate from Evans's theorem, which means that the degree of color balance correction is reduced.

Further, the CPU 7 calculates the ratio of performing the color balance correction using the white level and the ratio of performing the color balance correction using the average value, based on the white level dependency WDSA. Further, a color balance correction ratio is obtained from the sum of the two (step S9). In step S9, DMAX / RMAX is a correction term based on the R component of the white level, and AVEMAX / AVER is a correction term based on the R component of the average value. Then, BALR is obtained by multiplying each by the weight of the degree of dependence WDSA, (1-WDSA). The same applies to BALG and BALB.

However, the color balance ratios BALR, BALG, and BALB need to be set to one, and are thus normalized (step S10).
Further, a color balance correction amount is obtained from the color balance correction degree WSA (step S11).

On the other hand, in the case of the brightness correction, the CPU 7 calculates the ratio of the brightness correction using the white level from the white level dependency WDMAX of the brightness correction and the ratio of the brightness correction using the average value, that is, the brightness correction ratio. Ask for AE. Furthermore, brightness correction degree WA
The brightness correction amount WAE is obtained from VE. Here, DMAX representing the white level is 255, and the average value of all pixels is 127 (that is,
255/2). Then, the degree of dependence WDMAX,
The brightness correction amount WAE is obtained by applying a weight of (1-WDMAX).

Then, the color balance and brightness correction amounts γ _R , γ _G , and γ _B finally obtained by the product of the brightness correction amount WAE and the color balance correction amount represent the slopes in FIG. The CPU 7 calculates the closer slopes among (1) to (8) in FIG.
Select each of them, and look up table 4420R,
Set to G and B. The table of FIG. 35 (B) is also selected corresponding to (1) to (8), and the look-up table 41 is selected.
Set to 10A-R, G, B.

As described above, the method of the present embodiment obtains the average value and the R, G, B signals considered to be the white level from the R, G, B image signals taken into the memory from the SV camera or floppy, and further calculates the average value. In addition, a grade is obtained from a characteristic value obtained from the R, G, and B values of the white level using a membership function prepared in advance, and brightness correction and color balance correction of an image are performed according to the grade. It can correct the difference in color balance and the difference in recording level (brightness) caused by the difference in the maker and model of the SV camera. Further, there is an effect that excessive correction is prevented, and extreme correction such as whether or not correction is applied due to a slight difference in the level of the input image does not occur. Therefore, there is an effect that the correction is performed more naturally.

By creating and printing out an LUT as described above, a more faithful image can be reproduced (the above is called color control).

The color balance function described above is to change the R, G, B balance of a video signal input from an initial color balance state (shown in FIG. 49E) using Evans' theorem. For example, as a result of using the color balance function, if redness (R) is increased and blueness (B) is reduced,
The color balance display changes as shown in FIG. 49F.

After the color balance function is activated, if the user wishes to obtain the desired color tone, the color can be changed by pressing the color balance key shown in FIG. 49A. The operation method of this color balance is
It is omitted for the sake of description later.

In this embodiment, when adjusting the color balance, pixel data of a plurality of screens are sampled, and the color balance of the entire plurality of screens stored in the memory is automatically adjusted. Therefore, according to the present embodiment, automatic adjustment of the color balance can be realized with less malfunction.

Film Skiana 34 also uses an auto-changer,
By automatically storing images one after another and performing 24- or 36-sided printing, index printing of film images is possible.

<Image Forming by Layout at Arbitrary Position> In the above description, control for developing an image automatically and forming an image as shown in FIG. 34 (A) has been described. The invention is not limited to the example, and an arbitrary image can be developed at an arbitrary position to form an image.

Hereinafter, as an example of this case, “image 0” shown in FIG.
The case where “Image 3” is developed as shown in the figure to form an image will be described.

First, the color reader 1, the film scanner 34 or the SV is controlled by the same control as the image input control to the memory described above.
The four pieces of image information read from the recording / reproducing apparatus 31 are stored in the image memories 4060AR, 4060AG, and 4060AB as shown in FIG.

Then, the user operates the point pen 421 to designate and input a desired development position from the coordinate detection plate 420. For example, the deployment area
Specify and enter as shown in Figure 37. The image forming process in this case is shown in the block diagram of FIG. 27 (A) to FIG.
This will be described below with reference to the timing charts shown in FIGS. 38 and 39.

FIG. 38 is a timing chart at the time of image formation on the "l ₁ " line shown in FIG. 37, and FIG. 39 is a timing chart at the time of image formation on the "l ₂ " line in FIG.

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.

In the layout of the image shown in FIG. 37 (A), “Image 3” is the color reader 1 or the film scanner 34.
Alternatively, the image from the SV recording / reproducing device 31 is rotated by 90 degrees.

This image rotation processing is performed in the following procedure. First,
The image is transferred from the 4060AR, 4060AG, 4060AB to the work memory 4390 by the DMAC (Direct Memory Access Controller) 4380 in FIG. Next, after performing a known image rotation process in the work memory 4390 by the CPU 4360, the DMAC 4380 transfers the work image from the work memory 4390 to the 4060AR,
The image is transferred to 060AG and 4060AB, and the image is rotated.

The position information of each image laid out and input by the digitizer 16 is stored in the video processing unit 12 shown in FIG.
Is sent to the image storage device 3 through the same route as described above.

The position information is read by the CPU 4360 via the signal line 9460. As described above, the CPU 4360 performs the program of the area signal generator based on the position information.

The system controller 4210, which has received the development position information for each image, executes an enlargement / interpolation circuit corresponding to each image.
4150-0 to 3 operation enable signals 9320-0 to 3320, counter enable signals 9102-0 to 3 and LUS selection signals 4111A to 4111D
Generates the respective selector control signals to obtain a desired image. At this time, when printing the SV image, the LUT is set by the algorithm described above.

In the layout at an arbitrary position in this embodiment, for example, the counter 0 (4080-0) is set to the image 0, the counter 1 (4080-1) is set to the image 1, and the counter 2 (4080-2).
Operate on image 2 and the counter 3 (4080-3) operates on image 3 respectively.

The control at the time of image formation on the “l ₁ ” line shown in FIG. 37 will be described with reference to FIG.

“Image 0” is read from the image memories 4060AR, 4060AG, and 4060AB by the counter 0 (4080A-0).
The address to the address "0.5M" (the storage area of "image 0" shown in FIG. 36) are read. The switching of the outputs of the counters 4080A-0 to 3 is performed by the selector 4070A under the control of the counter controller 9141A.

Similarly, the reading of “image 1” is performed by the counter 1 (4080).
According to A-1), addresses from "0.5M" to "1M" (the storage area of "image 1" shown in FIG. 36) are read. The timing of this reading is shown as 9160AR, AG, AB in FIG.

The data of “Image 0” and “Image 1” are LUT4110AR,
Masking / black extraction / UCR circuit 41 via 4110AG, 4110AB
20A, where it becomes a color signal 9210 in a frame sequence. The frame-sequential color signal 9210 is parallelized by the selector 4120, divided for each pixel, and stored in the FIFO memories 4140-0 and 4140-1.
Sent to An operation permission signal 9320 from the system controller 4210 to the enlargement / interpolation circuits 4150-0 and 4150-1 is provided.
When −0,9320-1 is enabled, the enlargement / interpolation circuit 41
50-0, 4150-1 enable the FIFO read signals 9280-0, 9280-1, and start the read control.

The FIFO memory 4140-0,4140-1 outputs the signal 9280-0,92
At 80-1, transfer of image data to the enlargement / interpolation circuits 4150-0 and 4150-1 is started. Then, the enlargement / interpolation circuits 4150-0 and 4150-1 perform layout and interpolation calculations according to the area specified by the digitizer 16 first. This timing is shown at 9300-0,9300-1 in FIG.

The “image 0” and “image 1” data on which the layout and the interpolation have been performed are selected by the selector 4190,
The signal passes through the edge filter circuit 4180 and is input to the LUT 4200. Subsequent processes up to the connector 4550 are the same as those described above, and a description thereof will be omitted.

Next, the timing of the “l ₂ ” line shown in FIG. 37 (D) will be described with reference to FIG.

Enlargement / interpolation circuit from image memory 4060AR, 4060AG, 4060AB
The processing up to 4150-1 and 4150-2 is substantially the same as described above.

However, since “image 1” and “image 2” are output in the “l ₂ ” line, the counter 1 (4080-1)
And the counter 2 (4080-2), FIFOs 4140-1 and 4140-2, and enlargement / interpolation circuits 4150-1 and 4150-2 operate. These controls are performed according to control signals from the system controller 4210.

As shown in FIG. 37, in the “l ₂ ” line, “image 1” and “image 2” overlap. In this overlapped portion, either one of the images or both of the images can be selected by a control signal 9340 from the system controller 4210.

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

The signal from the connector 4550 is connected to the color reader 1 by a cable. Therefore, the color reader 1
The video interface 201 selectively outputs an image signal 205R from the image storage device 3 to the printer interface 56 through a signal line path shown in FIG.

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

As described above, when the start button of the operation unit 20 is pressed, the printer 2 starts operating and starts transporting the recording paper. When the recording paper reaches the tip of the image forming section,
The signal 551 is output. The ITOP signal 551 is sent to the image storage device 3 via the color reader 1. Image storage device 3
Are stored in the respective image memories 4060AR and 406 under the set conditions.
The image data stored in 0AG, 4060AB is read, and the above-described processing such as layout, enlargement / interpolation, etc. is performed.

<Memory expansion continuous shooting> The image data sent from the host computer 33 is GPIB
The data is input via the 4580, temporarily expanded in the work memory 4390, written in the image memories A, B, C, and D, and similarly read out by the above-described means, thereby obtaining a print output. For example, as shown in FIG. 43, the image transferred to the image storage memory is stored in the counter O (4080A-
0), the image is similarly printed out in the area of image 0 in FIG. 37 (A).

Also, by sending layout coordinate information, enlargement magnification, and print command from the host computer, image formation with an arbitrary layout can be performed under the control of the host computer in the same manner as described above.

Further, since the enlargement magnification can be set arbitrarily, an enlarged output image can be obtained beyond the limitation of the print paper.

FIG. 37 (G) shows an example in which a memory-capable image is divided into four print sheets and enlarged and printed (hereinafter referred to as enlarged continuous shooting). The details will be described below.

FIG. 37 (F) shows the counter 0 4080 shown in FIG. 27 (C).
FIG. 3 is a diagram schematically illustrating an image stored in a memory area read by A-0.

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

In the figure, the division size is a in the H direction and b in the V direction. These are used to calculate the starting address read by the counter.

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

The image forming process is started by the ITOP signal 551 shown in FIG. 40, and is read out from the system controller 4210 to the address a in line 1 by the counter enable signal 9102-0, expanded and sent to the color reader 1. When the reading is completed, the read counter calculates the start address of the next line, repeats the reading, reads the data up to the b line, and completes the printing of the first sheet. Subsequently, until the second sheet ITOP signal 551 arrives, the first address 2 of the second sheet is calculated, and the processing is sequentially repeated, and printing is continuously performed up to the fourth sheet while calculating the first address. Finally, by joining the print images, an enlarged image can be obtained.

<Non-Rectangular Image Synthesis Using Memory E> Next, a non-rectangular image synthesizing process using the bitmap memory E will be described.

For example, a case will be described in which the output area of the image 0 is formed in a heart shape as shown in FIG.

As described above, in consideration of the size of the area of the image 0 to be output first, the heart-shaped binary image is stored in the bitmap memory E.
Expand to Next, in the same manner as in the preceding paragraph, the development area of each image is designated and input from the color reader 1 using the digitizer 16. At this time, only the selection button for the non-rectangular area for image 0 is selected from the operation unit. The position information and the processing information of each of the designated images are sent to the image storage device 3 via the first video processing unit 12. The transmitted information is read by the CPU 4360 through the signal line 9460, and the output timing of the image is programmed based on the information as described above.

Upon receiving the I-TOP signal from the color reader 1, the image storage device 3 starts reading the image from the memory, and the image is actually synthesized when passing through the selector 4230 in FIG.

FIG. 41 is a schematic diagram showing the internal configuration of the selector 4230 of FIG. 27 (B). Reference numeral 3010 controls the data set in the register by the register 1 so that the CPU can programmatically select 8-bit density data or a BI signal from the bit map memory from the CPU. Numerals 3020 and 3030 are such selecting gates. For example, if 8 bit density data is selected, OR
At the gate 3040, the image signal and the bitmap are synthesized.

On the other hand, when the BI signal is selected, the selector 3050 becomes the select signal, and the image signal of the density of the data set in the register indicated by 3050 by the BI signal and the image data 93 from the memory.
80 can be selected and output.

When performing non-rectangular image synthesis, the register 2 is normally set to "0". Image data 9380 read sequentially
Are non-rectangularly cut out by a selector 3050, which is output from a bit map and is a non-rectangular area signal BI select signal, to enable non-rectangular image synthesis.

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

That is, if the above-mentioned IB signal is used as the signal 206 to be input to the video interface circuit 201 in FIG. 2 and the video interface circuit 201 is used in the state shown in FIG. Can be performed.

Further, in the present embodiment, an image in the image storage device 3 can be combined with a color image read by the reader 1 in real time.

That is, as described above, the ITOP signal 55 of the color printer 2
The image is read out from the image storage device 3 in synchronization with 1, and at the same time, the color reader 1 also starts reading out the reflection original 999 by the full color sensor 6 in synchronization with the ITOP signal 551. Since the processing of the color reader 1 is the same as described above, the description is omitted.

The combination of the image information from the image storage device 3 and the image information from the color reader 1 will be described below with reference to the timing chart of FIG.

FIG. 37 (C) shows a portion other than images 0 to 4 in FIG. 37 (A), a reflection original 999 at l ₁ when a reflection original read by the reader 1 is synthesized, and an image storage device 3.
This is a timing chart obtained by synthesizing signals from.

The image information of the color reader 1 read out in synchronization with the ITOP signal 551 is the output signal 559RGB of the black correction / white correction circuit.
Next is output in synchronization with the HSYNC in l ₁ of Figure 20. As for the image information 205 RGB from the image storage device 3, only the area specified by the digitizer 16 is output.
These two types of image information are input to the video interface 101, and the image of the color original is output from the synthesizing circuit 115 except for the area designated by the digitizer 16, and the digitizer 16
Information from the image storage device 3 is output to the area designated by.

In the above embodiment, as a means for setting a non-rectangular area, a mask pattern of a desired area shape is prepared in advance, and read into a bitmap memory by reading the mask pattern into a bitmap memory.

Further, in this embodiment, as shown in FIG. 27 (D-1), a bit map memory is connected to a CPU bus so that the CPU can develop a mask pattern in the bit map memory. For example, in the case of a star, rhombus, hexagon, or other fixed mask pattern that is considered to be frequently used, the data or the program that generates the data is stored in the program ROM
Alternatively, the program can be stored in the font ROM 4070, and when used, a program can be started to automatically generate a mask pattern.

With the above configuration, there is no need to create and read a mask pattern, and it is possible to easily create a mask pattern in the bit map memory, and to further easily perform image composition as shown in FIG. 37 (B). be able to.

Further, in the present embodiment, for example, the CPU 4360 converts the code data transmitted from the computer 33 into a second character.
Referring to the font ROM 4070 shown in FIG. 7 (D-1), the character font can be developed on the bit map memory indicated by E. In this way, the character font can be freely written in the bit map memory, and the AND gate 3020 shown in FIG.
By deactivating 30 and synthesizing the image data 9380 and the image on the bit map memory by the OR gate 3040, it is possible to easily synthesize characters with various stored image data.

Further, by activating a pattern generation program by the CPU 4360, for example, the ruled line K can be written in the bit map, and the ruled line and the image data can be easily synthesized as shown in FIG. 37 (D). In addition, various fixed patterns can be provided as a CPU program.

Further, the character data and the image data from the font ROM 4070 previously written in the bit map memory are synthesized,
As shown in FIG. 37 (E), an image having a message on the lower surface of each image shown in FIG. 34 can be obtained. As described above, these characters can be developed by sending character codes from the host computer, or can be read from a reader and set.

<Description of Monitor TV Interface> As shown in FIG. 1, the system of this embodiment can output the contents of the image memory in the image storage device to the monitor TV 32. It is also possible to output a video image from the SV recording / reproducing device 31.

This will be described in detail below. Image memory 4060AR, 4060AG, 40
The video image data stored in the 60AB is read by the DMAC 4380, and the display memory 4060M-R, 4060M

On the other hand, as described above, the system controller 4210
By controlling the control signals output from the memory to each memory, a desired image can be stored in the image memory and also in the display memory M at the same time.

Also, as shown in FIG. 27E showing the details of the display memory M, the display memories 4060M-R, 4060M
-G, 4060M-B, the video image data stored in LUT44

The signal is converted into a signal 4590G and a B signal 4590B and output.

On the other hand, from the display controller 4440, the SYNC signal 9600 is synchronized with the output timing of these analog signals.
Is output. This analog R signal 4690R and G signal 4590
By connecting the G and B signals 4590B and the SYNC signal 4590S to the monitor 4, the contents stored in the image storage device 3 can be displayed.

Also, in this embodiment, the image displayed by transmitting a control command from the host computer 33 shown in FIG. 1 to the image storage device 3 via the 4580 and the GPIB controller 4310 shown in FIG. Can be trimmed.

The CPU 4360 controls the display memories 4410R, 4410G, and 4410B to display the image memories 4060AR and 4060 based on the area information instructed and input by the host computer 33 under the same control as described above.
Trimming is possible by transferring only the effective area to AG, 4060AB.

Also, in response to the area instruction information from the host computer 33, the CPU 4360 shown in FIG. 27 (B) sets the data in the comparators 4232, 4233 and the RAM 4212 of FIG. 1 and SV recording / playback machine
By inputting the image data from 31, the trimmed image data can be stored in the 4060AR, 4060AG, and 4060AB.

Next, when a plurality of images are stored in the image memories 4060R, 4060G, and 4060B, the layout of each image can be made by using the monitor television 32 and the host computer 33 when recording with the color printer 2.

First, the size of the recording paper is displayed on the monitor television 32, and the layout information of each image is input by the host computer 33 while watching this display, whereby the layout of each image to be recorded by the color printer 2 is possible. .

At this time, the reading control of the stored information from the image memories 4060AR, 4060AG, and 4060AB to the color printer 2 and the recording control in the color printer 2 are the same as those in the above-described embodiment, and thus the description is omitted.

<Explanation of Computer Interface> The system of the present embodiment has a host computer 33 as shown in FIG. The interface with the host computer 33 will be described with reference to FIG.

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

For example, when image data is transferred from the host computer 33 via GP-IB, the image data is transferred line by line.
It is received by the GP-IB controller 4310 and stored in the temporary work memory 4390. The stored data is DMA-transferred from the work memory to the image storage memories AB and CD and the monitor display memory M as needed, and data is newly received from the GP-IB controller 4310 again, and the image transfer is performed by the above-described repetition. .

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

42. In FIG. 42, reference numerals of the components of the embodiment are renumbered. From the host computer 33,
First, the image size to be transferred is sent. That is, the image size concerning the CPU 2403 is read from the host computer 33 via the input terminal 2401 and the GP-IB controller 2402. Next, the image data is read line by line and stored in the temporary work memory 2404. The image data stored in the work memory is sequentially transferred to an image storage memory 2406 and a display memory 2407 by a DRAM controller 2405 (hereinafter referred to as DMAC) (here, R,
G and B are put together). The details will be described below. For example, as shown in FIG. 43, addresses are assigned to the image storage memory 2406 and the display memory 2407, and images are stored. In the figure, the lower address corresponds to the H direction, and the upper address corresponds to the V direction. For example, if the point A is 100H in the H direction and 100H in the V direction, the address of the point A is 100100
H. Similarly, the display memory also assigns the lower address and the upper address in the V direction. Here, for example, it is assumed that the images sequentially transmitted are reduced to the same size to the image storage memory 2402 and reduced to 3/4 to the display memory 2407 and transferred.

First, as described above, the image size and reduction ratio of the image sent from the host computer are set in the DMAC, while the DRAM controllers 2408 and 2409 set the storage start address and the reduced image size. After the above setting is completed, a command is sent to the DMAC 2405 by the CPU to start the image transfer.

The DMAC 2405 gives an address and a signal to the work memory 2404 and reads out image data. At this time, the address is sequentially incremented, and when the reading of 1H is completed, the next one line is received again from the host computer and stored in the work memory. On the other hand, at the same time, DMA controllers 2408 and 2409
▼ and ▲ ▼ are given to sequentially write image data. At this time, the DRAM controllers 2408 and 2409 count the ▲ signals, and sequentially increment the write address from the set top address. When the writing in the H direction is completed, the address in the V direction is incremented, and the writing is performed from the beginning of the next H.

When the above transfer is performed, the DMAC has a function similar to that of the rate multiplier for ▲, and therefore, the reduction is performed by thinning out ▲. For example, if a reduction of 3/4 is set as described above, the DMAC
In the direction, ▲ ▼ is thinned out once in four times, and in the V direction, one line section ▲ ▼ is not output for every four lines. As a result, ▲ ▼
The reduction is performed by controlling the writing to the memory.

FIG. 44 shows a timing chart. The read address is input to the work memory 2404 as shown in the figure, and ▲ ▼
Signals cause data to appear on the data bus. At the same time, the write address is input to the storage destination address, and ▲ ▼
Data is written by the signal. At this time, ▲ ▼
When the signal is decimated, the write address is not incremented as described above, and no write is performed.

<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 unit 20 of the color reader 1.

Is displayed as shown in FIG. When the area indicated by, for example, A in FIG. C is selected, the display shifts to the figure shown by D, and the index No. of the SV image to be formed in the set area is displayed.
Is set using the numerical keys in the D and E diagrams of FIG. 50 (B). By repeating such designation, index numbers of a plurality of SV images are designated.

Next, when the start key of the operation unit 20 is pressed, the SV image of the set index No. is taken into the image storage device 3 and printed out in a predetermined area. This procedure will be described with reference to FIG. 50 (C).

When the start key of the operation unit 20 on the color reader side is pressed, a registration request is issued from the color reader 1 to the image storage device 3.
The image storage device 3 sends a track of the SV floppy of the SV player 31 so as to correspond to the designated index No.
That is, an instruction to change the track being reproduced is issued, and the image information corresponding to the index number is stored in the memory. After registering all the images corresponding to the index No. set by the operation unit 20, the image storage device 3 sends a registration end message to the color reader 1.

The color reader 1 sends an image print area of each index No., that is, layout information to the image storage device 3 and sends a start request signal.

The image storage device 3 sends the SV image information to the color reader 1 at the designated position in accordance with the synchronization signal from the color printer 2. The color reader 1 processes the image information from the image storage device 3 and sends it to the color printer 2 to form an image.

The SV free layout shown in FIG. 50 (B) will be described.

The SV free layout can be a rectangular area layout or a non-rectangular area layout.

First, a free layout of a rectangular area will be described, and then a layout of a non-rectangular area will be described.
These rectangular and non-rectangular areas can also be output together during image formation.

SV free layout of rectangular area first
An area area is designated by the point pen 421 of the digitizer 16 shown in the figure. Next, as shown in FIG. 50 (B), H or I, an SV index No. is designated. By repeating such an instruction, the layout positions of the plurality of SV images and the corresponding index numbers are indicated.

Next, by pressing the start key of the operation unit 20, the SV image of the set index No. is taken into the image storage device 3 and printed out according to the predetermined layout information. Details are omitted because they are the same as those of the fixed layout print described above.

The SV free layout of the non-rectangular area functions by pressing a non-rectangular key in the F diagram of FIG. 50 (B). For the setting of the non-rectangular area, four types of circle, ellipse, R rectangle, and free can be selected. These selections are made according to the K diagram in FIG. 50 (B).

When laying out a circle, the center of the circle is indicated by the point pen 421 of the digitizer 16 as shown in FIG. 50 (B). Similarly, after instructing the radius of the circle as shown in Fig. P, pressing the OK key causes the SV index No.
Is selected according to the H or I diagram of FIG. 50 (b).

Here, the information of the circles designated in the O and P diagrams of FIG. 50 is stored in the bit map memory 91 of the color reader 1 through the signal line 505 from the digitizer 16.

Next, by pressing the start key of the operation unit 20, the SV image of the specified index No. is fetched into the image storage device 3 and the position and size of the circle stored in the bit map memory 91 of the color reader 1 are determined. , Image storage device 3
Performs layout and scaling, and transfers the image information of the color reader SV.

The color reader 1 outputs a circular area signal in synchronization with the color printer 2 from the bit map memory 91 in which the information on the circle is stored, and switches the synthesizing circuit 115 in the video processing unit 12 of the color reader 1. . The synthesis circuit 115 outputs 00H (white) when the area is outside the circle.
The image information is output from the image storage device 3 and transferred to the color printer 2. This is shown in FIG. 50 (D).

At this time, the image storage device 3 performs magnification so that the diameter of the circle information in the bitmap memory 91 becomes equal to the shorter length of the aspect of the output image information.

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

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

It functions by pressing the free key in the K diagram of FIG. 50 (B).

Free layout is digitizer 16 point pen
By tracing the upper surface of the digitizer 16 with 421, the information is stored in the bit map memory 91 of the color reader 1.
Is written in This is shown in FIG. 50 (D). Since the image forming process is the same as the above-described circle, the description is omitted.

The SV composite print shown in FIG. 50 (B) J will be described. The layout area can be specified in a rectangular area or a non-rectangular area as in the free layout described above.

The designation of the layout area and the designation of the index number are omitted because they are the same as in the above-described SV free layout.

Next, by pressing the start key of the operation unit 20, the SV image of the set index No. is fetched into the image storage device 3, and the SV image is placed outside the predetermined area outside the predetermined area. The image of the upper reflection document 999 is combined and printed out.

The SV index display, the SV index print, and the SV layout print have been described above, but an operation combining them will be described.

The operation flow is shown in FIG. This flow chart allows you to select an index number during SV layout.
It shows an operation performed using the V index display or the SV index print.

First, in order to perform the SV layout, the SV index display shown in FIG. 33 (C) or the SV index print shown in FIG. 34 (B) is performed.

Next, an operation for performing an SV layout is performed, and an SV fixed layout, an SV free layout, and an SV combined layout are selected. The details are omitted because they have been described above.

Select the image of the area of each layout by SV index display or SV index print described above,
This is shown in FIG. 50 (B), D, E, H, I. Indicate the index number.

At this time, since the image information in the SV jacket is displayed on the SV index or the SV index print, the image is formed on the monitor or the copy paper, so that the desired image can be indicated.

Such operations are repeated, and after a plurality of images are stored in the memory, the image is formed by pressing the start key of the operation unit 20. The image formation is omitted since it has been described above.

<Control by Host Computer> The system of this embodiment has a host computer 33 as shown in FIG. The interface with the host computer 33 will be described with reference to FIG.

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

The image data of the color reader 1 and the SV recording / reproducing apparatus 31 are sent to the host computer 33 by the GP-IB controller 4310 connected by the connector 4580, and are stored in a storage area in the host computer 33, and are used for enlargement / reduction processing. ,
Conventionally, clipping of one portion of image data and layout of a plurality of image data have been performed. However, in this case, since the amount of color image data becomes considerably large, the color reader 1, the SV reproducer 31, and the host computer 31 can be connected through a general-purpose interface such as GP-IB.
The data transfer time between 33 and is very long. Therefore, instead of directly sending the input image data to the host computer 33, a command determined from the host computer 33 is sent to the GP-IB controller of the image storage device 3, and the CPU 4360 decodes the command, Color reader 1
And the input image data of the SV recording / reproducing device 31 and specifying only the image area that is really needed, the other parts are not stored in the memory, the memory is used effectively, and the host computer 33 There is no need to transfer image data.

Further, even if the input image data is not stored in the storage area in the host computer 33 according to a command from the host computer 33, the image storage device 3 can store the image data in the image memories 4060A-R and 406.
A plurality of image data can be stored in 0A-G and 4060A-B, and image processing such as layout and enlargement / reduction of each image is not performed on the host computer 33 side, but only by a command from the host computer. , The CPU 4 of the image storage device 3
Since the processing / instruction is performed by the 360 on the input image data, the image transfer between the host computer 33 and the image storage device 3 does not take much time, and the processing time can be reduced. ing.

As described above, how the image storage device 3 stores and handles input / output images in response to an instruction from the computer 33 will be described in detail.

All input / output image data stored in the image storage device 3 is handled in the image storage device as an image file. Therefore, the memory A (4060) of the image registration memory
A), memory B (4060B), memory C (4060C), and memory D (4060D) function as RAM disks,
The image file to be stored is managed by the image file management table 4361 using the file name as a key (FIG. 51).

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

The CPU 4360 can also combine some of these basic blocks by using the image file management table 4361 and manage them so as to form one large image file. At this time, management data such as the image file name, the image data size thereof, the protection of the file, and the configuration of the registration memory are all 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 registers the image as an image file in the image storage device at the same size or reduced size. Therefore, if the size of the image to be registered is increased and registered, the original image from the reader 1 approaches the original size,
Since the reduction ratio is reduced, the quality is improved when the recorded image file is output to the printer 2 or the like.

When the CPU 4360 inputs image data from the input device such as the reader 1 and the computer 33, the image file name used as a key is given a file name in a configuration as shown in FIG. 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 an arbitrary image file.

The structure of the image file name is composed of eight characters (ASCII code) of the name of the image file and an extension indicating the type of image of the image data.

The type of the image to be handled is distinguished by the extension, and the registration memory 40 has a structure corresponding to the image type.
It will be registered and managed in 60.

The image type is RGB type luminance image data when the extension is “.R”, CMYK type density image when “.C”, “.P”
In this case, it means image data in which any 256 colors can be set from 16.7 million colors of the 8-bit pallet type. Also,".
At the time of "S", a special file having a special meaning in the image storage device 3 and having a special structure is shown.

A coordinate system for handling images in the image storage device is composed of an origin serving as a reference, an X direction representing a width <width> direction of the sheet, and a Y direction representing a height <height> direction (52nd direction).
Figure).

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

Analog input terminal (RGB, video) (4500, 4510, 4520R,
When an image from G, B, S) is input and registered in the registration memory, the input image is registered as an image as shown in FIG. The input image at this time is input with a size of 600 pixels in the X direction (width) and 450 pixels in the Y direction (height).

The coordinate system of the digitizer 16 is as shown in Fig. 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 origins correspond to the X and Y directions.

When viewed from the image storage device, the coordinate system of the reader 1 is
It should look like Figure 55. 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 described.

Image storage device 3 and computer through GP-IB4310
The types of data exchanged between the 33 are categorized as follows.

Command (instruction) Command from the computer 33 to the image storage device 3 Parameter Various arguments attached to the command Data portion ・ Image data Binary data of color (monochrome) image such as RGB, CMYK, etc. ・ Extended data Set in the image storage device 3 This is the data that is transferred when obtaining the existing data or rewriting the setting data.

Response data: ACK / NAK, response with additional information (RET) That 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.

The four types of data will be described below with reference to FIG.

As shown in FIG. 57, handling between the image storage device 3 and each input / output device reader 1, analog input 4500, 4510, 4520R, G, B, S, between the printer 2 and between the image storage device and the computer 33 The image data is classified into the following four types.

RGB data type CMYK data type 8-bit palette data type Binary bit map data type These image data are distinguished by the extension of the image file name described above. For example, on the computer 33 side
When the image file name attached to the SCAN command 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 with R.
Input control as GB-based luminance image, and in the image storage device,
Register as RGB type image data.

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

In the image storage device, the basic blocks of the memories A to D (4060A to D) of the registration memory are configured as shown in FIG. 60 as shown in FIG. , R image (4060A-R), G image (4060A-G), and B image (4060A-B). The image composition of the image is horizontal width
(Width) and height (height) of vertical length are the number of pixels (dots).

Specifically, an RGB color image has a depth of 8 bits (1 byte) for each pixel of R, G, and B, and has a three-frame configuration of R, G, and B. .

Accordingly, one pixel on the R surface has 256 gradations (0 to 255), and the three surfaces R, G, and B have a data structure of 256 × 256 × 256 ≒ 16.7 million colors.

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

The data structure is in the R plane from the upper left , And this configuration continues in the order of RGB.

The transfer of image data between the image storage device 3 and the input / output device and the computer 33 is in a transfer format as shown in FIG. That is, data is transferred in a frame-sequential manner.

FIGS. 62 and 63 show the image structure of the CMYK type image data and the transfer format thereof. C represents cyan, M represents magenta, Y represents yellow, and K represents black. In such a case, the memories A to D of the registration memories in the image storage device 3
The basic blocks (shown in FIG. 27A) are formed into an image configuration as shown in FIG. 31, and the basic blocks are assigned to each of them.

Specifically, a CMYK color image has a depth of 8 bits (1 byte) for each pixel of C, M, Y, and K, which is a 4-frame structure of C, M, Y, and K It has become.

Therefore, 256 gradations can be expressed by one pixel on the C plane, and the same applies to the M, Y, and K planes.

 0 represents low density and 255 represents high density.

The data structure is C-plane in order from the upper left , And this configuration follows in the order of CMYK.

FIGS. 64 and 65 show an image data image structure of an 8-bit pallet type and its transfer format.

The memories A to D (the 27th memory) of the registration memories of the image storage device 3
The basic block in FIG. A) is configured as shown in FIG. 64, and the basic block is allocated.

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

The 8-bit data value of one pixel is stored in the color index No. of the color palette table 4391 as shown in FIG.
, And can be set to any color set by the user.

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

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

The structure of the data is from the upper left of the image It is arranged in order of data.

67 and 68 show a binary bit map type image data image structure and its transfer format.

The binary bit map is stored in the memory E (the 27th
Registered using FIG. A).

This image data has the extension ".S" in the image file name.
Is stored in a memory E (FIG. 27A) in which only the binary bit map type can be registered. The image file name is "BITMAP.S".

In the memory E (FIG. 27A), a plurality of registrations cannot be made because the basic block is the entire memory.

Binary bit map type image data has an image configuration having a depth of one bit per pixel.

Therefore, there are two types of expressions of "0" and "1" per pixel. “0” represents white (no printing) and “1” represents the maximum density (black).

The data structure is such that data is set in 8 bytes in order from the upper left of the image, that is, 1 byte per 8 pixels, so that binary bit map type image data is
Direction must be a multiple of 8. height
The direction is arbitrary.

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

<Width>: The width of the image file (width) <height>: The height of the image file (height) 8: Because it is 8 pixels, it becomes 1-byte data.

Next, the configuration of response data to command transmission from the computer 33 to the image storage device 3 will be described with reference to FIG.

-There are basically the following types of response data excluding image data.

FIG. 69 shows the structure of the 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 of the commands use either of them as response data.

The ACK type response data is an acknowledgment of each command, and indicates that the command has been normally transmitted and decoded to the image storage device 3 side. Fixed value of 3 bytes, the first 1 byte is 2EH and the next 2 bytes are 00H ・ The NAK type response data is a negative response to each command. It is a response when an error occurs. The first 1 byte is 3DH. Two bytes are the error code.

(Error code) = (Upper byte) x (100 _(HEX) + (Lower byte) • The RET type (response with attached information) is a response to a command from the computer 33, and the necessary information is attached. The data is sent from the image storage device 3. The configuration is 8 bytes in total, and the first byte is a fixed value of the header (02H), followed by the first data to the seventh data. Each byte continues one byte at a time, and the content of each data differs depending on the command.

The commands are used by the computer 33 to control the input / output of image data to / from the image storage device 3 and the management of image files, and there are commands as shown in FIG.

A command performs a function with one instruction,
The parameters following the command are separated into those required.

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

The command and the parameter are sent to the image storage device 3 via the GPIB controller 4310 as a character string.
It needs to be converted to a character string representing a decimal number. Some of the parameters include a character string indicating an image file name.

FIG. 59 shows how these commands cause image data to flow between the computer 33, the image storage device 3, the input devices 1, 31, and the output devices 2, 32.

In response to the analog input specified by the command, the display controller 4440 performs through display setting in which data is directly passed to the analog outputs 4590R, G, B, and S for display. Note that examples of the type variable include “0” (set through display), “1” (set monitor monitor), and the like. Furthermore, the MONITOR command has a lower priority than other commands, and the setting of the through display is canceled by another DSCAN or SCAN command.

In response to 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 determination data to the computer.

The PPRSEL command is a command for selecting one of a plurality of paper trays specified by the <no> parameter to the control unit 13 in the same manner as described above, and is transmitted to the color printer 21 via the image storage device 3. Is output.

The SENSE command is used by the CPU 436 for the state of each of the image storage device 3, the color reader 1, and the color printer 2.
0 is a command for communicating with and obtaining the control unit 13 via the video interface and transmitting the data to the computer.

Next, a command transmission procedure from the computer 33 to the image storage device 3 will be described.

When the commands are divided into the basic commands for image input / output (i) Input / output selection command SSEL, DSEL (ii) Input / output status setting command SMODE, SAREA, DMODE, DAREA, RPMODE, ASMODE (iii) Input / output execution The commands are SCAN, DRSCAN, PRINT, MPRINT, DRPRINT.

As shown in FIG. 82, there is a basic procedure for transmitting a command for input / output of image data.

First, an input / output device is selected by using an input / output selection command.
The CPU 4360 analyzes the command and returns an ACK / NAK of response data to the command to the computer 33.

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

The input / output state setting command loses its effect when the input / output execution command is executed, and returns to the default state. Therefore, if the input / output execution command is executed without executing the input / output state setting command, the input / output state setting is set to the default value. If it is desired to set a specific input / output state when executing input / output, it is necessary to execute an input / output state setting command for each input / output execution (for each basic type).

Then, an input / output execution command for actually executing input / output of image data is sent, and the CPU 4360 returns response data of the RET type in response thereto, and in the case of an affirmative response (ACK),
The input / output of the actual image data is performed by the input / output device reader 1,
The processing is performed between the image storage device and the SV 31, the printer 2, the monitor 32, and the like.

 This input / output is the same as in the above-described embodiment, and the description is omitted.

The CPU 4360 uses the image file management table 4361 to check the attribute of the image file in advance in response to a command related to image file registration from the computer, or to register the memory capacity of the file (memory A to memory A).
D) It is possible to perform processing such as checking in advance A)) in FIG. 27 and notify the computer 33 side.

There are FNCHECK and DKCHECK commands as pre-check commands for this image file.

The procedure for checking this image file is
As shown in FIG. 3, first, the existence of the designated file of the image file and the attribute of the file are transmitted to the computer 33 as RET type response data, and further, the remaining capacity of the image file or the desired image A response as to whether the file size can be secured is returned as RET data.

The basic form of the file check can be incorporated into the basic form of the input / output command described above, and the image file can be checked and responded before executing the input / output.

 Next, the composition of the image file will be described.

In order to combine a plurality of images registered as image files in the registration memory 4060 of the image storage device 3 and output them to the color printer 2, it is possible to send an MPRINT command from the computer 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,
Register the file name temporarily above.

The designated file name is temporarily registered in the RAM by sequentially transmitting the MPRINT command sequence from the computer 33 as much as the plurality of layouts, and the computer transmits the PRINT command sequence when the last image of the plurality of layouts is obtained. When the CPU 4360 analyzes this PRINT command,
The CPU transfers the designated image data from the image memory to the color printer from the image file management table 4361 in the order of the image file names sent in the order of the MPRINT commands on the RAM. The combined output at that time is as described above.

As for the order of transmission of MPRINT from the computer and the order of priority of image synthesis by the PRINT command, the image specified later has priority as shown in FIG.

To combine a special file, which is a binary bitmap memory (memory in FIG. 27A), with an image file registered in the image storage device, the above-described MP
If the computer sets the special file name of "BITMAP.S" in the image file names specified by the RINT and PRINT commands and sends it, the CPU 4360 can combine multiple image files as described above. Combination with binary bitmap data is performed. In the present embodiment, the image of the binary bit map is basically switched to black when the dot is "1", and the portion of "0" is switched so that the output of another image file is prioritized. Such an example is shown in FIG.

Such switching is performed by the video interface of the reader 1.
The use of 201 makes the configuration of the image storage device simple.

As an image composition function, it is possible to combine and output an image file, a special file of the binary bitmap "BITMAP.S", and a reflection document of one reader.
The synthesizing operation described above is performed.

The above-mentioned operation by the command from the computer
It can be executed by MPRINT command and COPY command.

Specifying multiple image files by MPRINT using commands, and finally sending a COPY command to trigger
The 360 gives an instruction for a copy operation to the CPU on the color reader side, and can further combine and output the image file by the MPRINT command and the reflection original of the reader unit.

At this time, if an image file of "BITMAP.S" is specified in the MPRINT, synthesis with a binary bitmap can be performed.

In this embodiment, the priority order is automatically set to the lowest for the reflection original of one reader by the COPY command.
Can be the background of the image.

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

In this embodiment, as a color adjustment function, as shown in FIG. 79, the PALETTE command, the BALANCE command, and the GA command as commands from the computer corresponding to the color palette function, the color balance function, and the gamma correction function, respectively.
There are MMA command and BITCOLOR command.

The color pallet is used to set the color of the 8-bit pallet type as described above or to color the image data of the binary bit map type. To do this,
Set the color data to the palette number in the color palette. Specifically, 256 color data can be set, and data of 8 bits for each RGB is set.

By making the color data set in the color pallet 4362 in the image storage device 3 the same as the color pallet stored in the host computer, the color of the image output by the color printer 1 via the image storage device 3 and the host computer Can be the same as

The color palette table in the image storage device 3 is PALE
Palette table stored in image storage device 3 by TTE command
Can be set for each image file registered in. Therefore, when outputting an 8-bit pallet type image file with the extension “.P” using the PRINT and MPRINT commands, set the PALETTE command from the computer,
Thereafter, for example, a PR for setting RGB palette table data of 256 × 3 (768) bytes as shown in FIG. 91 to the palette table of the image storage device 3 via the GP-IB4580.
When the INT / MPRINT command is executed, the R, G, and B components of the currently set palette table 4362 are
The values are set to 10A-R, 4110A-G, and 4110A-B, and calculations for converting the luminance into the density are performed on the respective tables.

At this time, the 8-bit pallet luminance information is converted into density information by converting the pallet type image file data specified by the PRINT / MPRINT command through the LUTs 4110A-R, 4110A-G, and 4110A-B in which a pallet table is set. The images are sequentially output to an image output system and output by a color printer.

The 8-bit pallet type image is stored in the work memory 4390 when it is sent from the computer via GP-IB.
Each line is set, and the registration memory 4060−
The same data is set in R, 4060-G, and 4060-B, and it repeats sequentially.

The maximum number of 8-bit pallet tables that can be set by the PALETTE command is 16, and can be set for each 8-bit pallet type of image data when combining with a plurality of layouts.

Before virtually outputting a plurality of 8-bit pallet type images by the MPRINT command, the CPU 4360 temporarily registers the color pallet data (768 bytes) in the memory 4370 of the image storage device 3 by the PALETTE command.

This is repeated for a plurality of 8-bit pallet images to be laid out and synthesized.
The command causes the actual output to be executed.

The image storage device 3 sets the pallet table of the 8-bit pallet image according to each MPRINT command set up to that time by the PRINT command from the memory 4370 to the output color pallet table 4362 when the pallet is sequentially synthesized and output. Thus, a plurality of images can be combined and output to the printer 2 as described above.

Next, in the setting of the color balance, setting of two types of color balance of the RGB type and the CMYK type can be distinguished by the type parameter. This setting is
Can be set by NCE command.

RGB color balance is LUT4110A-R, 4110A-G, 4110
-B1, C2, C3 of BALANCE command
Set by the value of ± 50% of the parameter, and calculate the conversion from luminance to density.

The CMYK color balance sets the gradient of the density for the LUT4200 by the value of the C1, C2, C3, and C4 parameters of the BALANCE command ± 50%.

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

The GAMMA command is output from the printer 2 to RGB-type image file data based on the type parameter.
Memory 437 in advance to enable color reproduction on the CRT
0 The data of the LUT registered on 4110A-R, 4110A-G,
By setting the values to 4110A-B and adding a conversion operation from luminance to density, RGB image data subjected to CRT correction of γ = 0.45 can be reproduced in color and output.

The BITCOLOR command is for the binary bitmap memory (special file “BITMAP.S”) (memory E in FIG. 27 (A)), the upper left (sx, sy) coordinates, size width × heig
In the range of ht, the color of the index No. of the color palette 4362 specified by the index parameter can be colored when outputting the binary bitmap of “BITMAP.S” to the color printer 2 as described above. Enabled by command. Sx, sy, by BITCOLOR command
The width, height, and index parameters are stored in memory 4 of CUP4360.
It is possible to hold more than one on 370. Then, “BIT” is actually added to filename by MPRINT or PRINT command.
When a file name of "MP.S" is specified, the CPU 4360 is the CP of the control unit 13 of the color reader 1 / color printer 2.
For U22, the parameters of the area of sx, sy, width, height and the index of the color pallet corresponding thereto are transmitted from the image storage device 3 via the video interface.
Sends 3 bytes of RGB component color data in the color palette table 4362 corresponding to No (index parameter) (repeats sequentially when multiple areas are specified by the BITCOLOR command), the control unit
13 sets these parameters in the programmable synthesizing unit 115 so that a designated area can be colored in a designated area when outputting a binary bit map 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 executes the binary bit map data of "BITMAP.S" by the PRINT or MPRINT command (the memory E of FIG. 27A). ) Can be colored and output via a video interface by a command from a computer.

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

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

The REMOTE command described above is a command from a computer that performs remote control.
(Fig. 92).

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

In the image recording device remote state, only the image storage device 3 can be controlled by a command from the host computer 33. At this time, the color reader / color printer can perform a copying operation by itself as a copying machine.

The local state is a local state (a state in which control cannot be performed) from both the color printer and the color reader from the host computer. The local state is specified by a remote control from the operation unit of the color reader 1 or a REMOTE from the host computer. The remote status will be established as soon as the command is issued.

The copier remote state can be controlled by setting the image storage device 3 to a remote state in accordance with an instruction from the operation unit of the color reader 1. At this time, the command from the computer cannot execute the function 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.

According to the type parameter of the REMOTE command, the CPU 4360 communicates with the CPU 22 of the control unit 13 of the color printer 2 and the color reader 1 via the video interface 201, so that the computer can indicate the four remote / local states described above. it can.

<Remote / Local Control> The switching between the remote / local states and the control of the system in each state will be described with reference to FIGS. 99 to 101.

Fig. 99 shows the control unit 13 in the color reader.
(Hereinafter abbreviated as color reader controller)
It is a control flow about a local state. First, powe
At the time of r on, communication is performed with the system controller 4210-2 in the image storage device in S101, and the state of the system at that time is received. Next, in step S102, the system determines whether the system is in the system remote state. If so, in step S103, a message as shown in FIG. 101A is displayed on the liquid crystal touch panel on the operation unit 20 of the color reader. At this time, the keys on the operation unit 20 are not accepted except for the remote key 20-1 shown in FIG. Next, in S104, it is determined whether or not a remote / local state switching command has been received from the system controller 4210-2.
Switching processing from 10-2 to the designated state is performed. In this switching process, if the color reader is already operating in a predetermined state, for example, if it is operating as a copier, switching cannot be performed. In addition, there is a case where an attempt to perform the switching results in an abnormal operation and a malfunction. In this case, the switching is not performed, and the system controller 4210-2 is used.
Notify the failure.

In S105, it is determined whether or not another command shown in FIGS. 71 to 80 has been received from the system controller 4210-2.
If it has come, in S108, control the color reader and the color printer to control its commands such as image registration and image printing,
Execute composite printing and the like.

In S106, it is determined whether or not the remote key on the color reader side has been pressed.
It requests the 4210-2 to switch the remote / local state. This switching is to change the system remote state to the remote state of the image storage device from the color reader, and the system controller 4210-2 performs the switching if the switching is possible, and the color reader controller if the switching fails.
Inform 13 that you failed. If the color reader controller 13 fails, the message shown in FIG. 101B is displayed.

Next, when it is determined in S102 that the system state is not the system remote state, all keys on the operation unit 20 are valid. In S110, it is determined whether or not a remote / local state switching command has been received from the system controller. If so, in S116, switching processing to the designated state is performed in the same manner as in S109.

In S111, it is determined whether or not a (key for using the image recording apparatus) on the operation unit 20 has been pressed. These keys are keys on the operation screen that is called by the external device key 20-2 on the operation unit 20, and when this key is pressed, first, S112
To determine whether the remote / local state is the copier remote state, and if so, in step S114, controls the image storage device 3 to perform processing corresponding to the input key operation. On the other hand, if it is not in the copier remote state, communication is performed with the system controller 4210-2 in S113, and switching processing to the copier remote state is performed. If this switching is successful, proceed to S114,
If it fails, the message shown in FIG. 101C is issued.

In S115, it is determined whether or not another key is pressed,
If pressed, the color reader and color printer are controlled in S114 to perform key processing.

FIG. 100 is a control flow for the remote / local state of the system controller 4210-2 in the image storage device 3. First, in S201, it is determined whether or not a command from the host computer has been received.
To determine if it is a REMOTE command, and if so,
In S204, communication with the controller 31 on the color reader side is performed, and remote / local state switching processing is performed. Then S2
At 05, it is determined whether the received command is a command using only the image storage device, for example, a SAVE command, a LOAD command, etc., and if so, at S206 the remote / local status is changed to the image storage device remote status or the system status. Determine if it is in remote state. In these states, since the image storage device is usable by the host, the command sent from the host in S208 is executed.

On the other hand, when it is not in these states, communication with the color reader is performed in S207, and switching processing of the remote / local state is performed. If the switching succeeds, the process proceeds to S208. If the switching fails, the host is notified of the failure and the command is not executed.

S209 means that the command received from the host is a command that also uses a color reader / color printer, for example, PRIN.
It is determined whether the received command is a T command, a SCAN command, or the like. If so, it is determined in S210 whether the remote / local state is the system remote state. In this state, the color reader / color printer can be used by the host.
In S212, the command is executed while communicating with the color reader controller.

At this time, the image data only moves between the color reader 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 reader controller 13 in accordance with the command from the host. During this time, the host does not need to control the system and can do other work.

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

On the other hand, when not in this state, the communication with the color reader controller is performed in S211 and the switching processing of the remote / local state is performed.

In S202, it is determined whether there is a command from the color reader, and if so, in S213, it is determined whether it is a request for switching between remote / local states, and if so, switching processing is performed in S214. In the case of other commands, it is determined in S215 whether the remote / local status is the copier remote status. In this state, the image storage device 3 can be used by the color reader controller.
Executes the command from the color reader controller. On the other hand, when not in this state, an error is notified to the color reader in S217.

In the above embodiment, for example, during image transfer from the host to the image storage device 3, the color reader can operate in the local mode. Therefore, even if time is required for image transfer from the host to the image storage device 3, the reader can perform the composite operation during this time.

Conversely, while no data is being transferred from the host to the image storage device 3, the image storage device 3 can be controlled from the color reader. Even if the color reader does not control the image storage device 3, the image storage device can be set to the remote state regardless of the host by turning on the remote key on the color reader side.

In addition, the image signal of the SV reproducer is stored in the image storage device from the color reader, for example, an instruction to store the SV multi-index image is output as described above. Can perform normal local mode operations.

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

FIG. 84 shows a procedure for registering image data from the input device to the image storage device 3 as an image file by the SCAN command. The basic part of the file check in the figure is
As described above, it is also possible to check in advance by inserting the procedure of FIG. 83.

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

FIG. 86 shows a procedure for inputting image data from an input device to an image storage device by using a DRSCAN command, performing registration, and transferring the image data to the computer 33.

FIG. 87 shows an example in which the image data on the computer 33 is output by the output device in the reverse of the DRSCAN command of FIG. 86.

 Next, an actual command embodiment will be described.

FIG. 93 shows an example of outputting an image in the host computer to a color printer as an example of single image output. For example, an example will be described in which a 1024 × 768 pixel RGB type image is centered within a range of 277 × 190 mm from the upper left (10,10) mm position of a sheet and printed out.

As an example of layout output of a plurality of images, an example is shown in which two RGB type image data in the host computer 3 are laid out on one sheet of paper and output by the color printer 2 (FIG. 94).

In this example, an example is shown in which two images of the RGB type of 1280 × 1024 and 1024 × 768 pixels are respectively centered within the range of the drawing and printed out.

When outputting a plurality of images, the image data is registered in the image storage device 3 from the host 3 one image at a time, the virtual output is performed, and the image data is output to the printer 2 (shown in FIG. 96). In some cases, the virtual output is registered and all the virtual outputs are output collectively (the case shown in FIG. 95). Both output results are the same.

FIGS. 97 and 98 show an example of taking an image from the reader 1 into the host 3.

In such a case, first, a range of an area (297 × 210 mm) corresponding to, for example, A4 size on the reader 1 is read as RGB type image data at a size of 1000 × 707 pixels, and the data is taken into the host computer 3.

As described above, according to this embodiment, the computer
The image data can be input / output only by exchanging a command (command) between the image storage device 3 and the computer 33 without holding the input / output image data on the computer 33. 1, printer 2, etc.)
Data transfer between them can be reduced.

In the above description, in the present embodiment, a so-called flat type sensor using a color line sensor is used as a means for photoelectrically converting the target image. However, the present invention is not limited to this. For example, a spot type sensor may be used. Is not limited to this type.

In this embodiment, a color printer that forms a full-color image by so-called frame sequential image formation is used as a means for image formation. However, such a color printer other than a frame sequential printer, such as an ink jet printer, may be used. Alternatively, a thermal transfer type printer or a printer called Cycolor may be used.

In this embodiment, the host computer, the image storage device, and the color reader communicate with each other as independent devices to realize the various functions described above, so that a novel system can be provided.

In this embodiment, the detecting means for detecting the color balance of the color image composed of a plurality of screens stored in the image storing means executes the flowchart shown in FIG. 35 (E).
Although the CPU is used to control software, the present invention is not limited to this, and the detection may be performed by hardware.

Further, in this embodiment, a correction means for performing color balance correction on the plurality of color images based on the color balance detected by the detection means is a lookup table 4420R, G, B or a table in which a table is written by the CPU. It consisted of a lookup table 4410A-R, G, B.

In addition, the correction is not limited to the method of rewriting the table in the storage device as in the above-described embodiment, but may be the rewriting of a lookup table provided on the color printer side.

In the above embodiment, N pieces of image data are sequentially fetched from the data of a plurality of screens in the memory 3 in accordance with the flowchart of FIG. 35 (E). May be taken in. When a plurality of screens are composed of five vertical screens and five horizontal screens arranged in a total of 25 screens, the center 2 of the 25 screens is used.
Data may be taken from four screens of × 2.

〔The invention's effect〕

As described above, according to the present invention, in an image processing apparatus that reads a plurality of independent images and combines them to generate an output image, the output image is generated based on image data sampled from each of the plurality of independent images. Since the color processing conditions for the entire output image are set, color processing conditions suitable for the entire output image can be set at high speed, and the color balance of the entire output image can be improved.
