[Prior art and its problems]

2. Description of the Related Art Conventionally, laser copy machines/printers or laser copy machines using a semiconductor laser as a light source are currently becoming widely used because they can digitally record images. Color versions of this laser beam printer (hereinafter referred to as LBP) or laser copy machine (hereinafter referred to as LC) are widely demanded in the market. Currently, there are two methods for realizing color LBP or color LC: the 1-drum method, which uses one photoreceptor drum, and the 4-drum method, which uses four photoreceptor drums. Some use one. Among these, color LCs using a 4-drum system usually read images at high density before printing, temporarily store each document in a storage device such as a DISC, and read them out sequentially to edit the document, so they have a large capacity. It requires several image memory and is very expensive.
・In addition, examples of products currently appearing on the market include the Response 300 series (product name: Cyte/
), 5TUD'10-800 Series (product name: Croffield), Pagematic (product name: Nippon Ink Company), etc., all of which are large and expensive, and are difficult to process. Since it is general-purpose, it has the disadvantage that it takes a long processing time.

[Object of the Invention] The present invention has been made to eliminate the above-mentioned drawbacks. Editing data and character information are key-inputted into an image processing menu displayed on a display, and the original size and editing detected by optical scanning are performed. By sequentially storing each edited image data in which color image data and text information are subjected to graphics processing and color processing according to the data in the same image data area set in the image memory, images can be created at high speed with a small capacity image memory. The purpose is to provide an image editing device that can be edited.

Next, the operation will be briefly explained.

With the editing data or parameters received from the controller 2 set in advance, the image data of R2O and B is input to the controller 2, and the image data is subjected to enlargement/reduction processing in the enlargement/reduction processing section 2a according to the image menu. The parallel movement processing unit 2b performs parallel movement processing, then the edge enhancement processing unit 4a of the pipeline processor 4 performs edge processing, and the masking processing unit 4b performs mask processing, etc., to process image data for each color. Binarization circuit 4C
The image data is converted into encoded color image data and stored in a designated area of the image memory 5.

Next, the editing operation will be explained with reference to the layout of the composite image shown in FIG.

In this figure, A, B, and C are images to be edited, and D is a composite image. It is assumed that the composite image to be created is, for example, A4 size. Further, it is assumed that the original document size of images A and B is A4 size, and image C is a part of the A4 size document.

First, an area of a composite image is formed in the image memory 5 by filling in the base color. Next, the image A is enlarged/reduced by the processing unit 2.
Then, the image B is reduced in size by the enlargement/reduction processing part 2a, moved to a predetermined position in the composite image by the parallel movement processing part 2b, and stored in the image memory 5. The image is moved to a predetermined position within the composite image and stored in the image memory 5. Subsequently, the image C is reduced by the enlargement/reduction processing section 2a, moved to a predetermined position within the composite image by the parallel movement processing section 2b, and then masked at a predetermined location by the masking processing section 4b and stored in the image memory 5. do. In this way, image A is included in the composite image.

By sequentially filling in B and C, the final composite image is obtained.

Next, text data editing work will be explained with reference to FIG. 4(a).

In this figure, A-D, A,, B1, C1, C2.

Sl and S2 are the same as in Fig. 3, and 5l (Xs
1, Ys1) indicates the upper left coordinates of the sentence S1 on the composite image, and 32 (Xs2, Ys2) indicates the upper left coordinates of the sentence S2 on the composite image. Furthermore, in general,
Since the color m-display has a low resolution and is not suitable for outputting thin characters, the following method may be used to edit text data.

(a) A monochrome high-definition display is used as the display 3a, text data is edited, and the framework of each color image A, B, and C is expressed and edited at a density of /\titch.

(b) A monochrome high-definition display and a color display are used as the display 3a, text data is edited on the monochrome high-definition display, and the framework of each color image A, B, and C is edited on the color display.

(C) A color display is used as the display 3a, and text data and each color image A are displayed.

Edit frameworks B and C.

Of these, methods (a) and (b) have problems in terms of cost, and the present invention employs method (C). The text data is edited using a word processor or the like using the display 3a. Editing text data will be described below in accordance with method (C).

First, frame information At + of each image A to C shown in FIG.
After inputting B1+ Cr l C2 (7), Figure 4 (a
) and the upper left coordinates S of S2! (X
s 1 , Ys 1), S2 (XS2.Ys2) are given from the keyboard 3b, and when the text data of sentences S1 and S2 is input from the keyboard 3b, a character generator (CG) not shown generates dot information. The text data is displayed on the display 3a, and the text S1 is converted into code information.
The text data of S2 and S2 are stored in the character code memory 8. At this time, if the character code memory 8 is configured to store one page of a document equivalent to A4 size, for example, the number of characters that can be written in this document is (210/3) x (2), assuming a minimum character size of 3 mm. !37/3
) = 6930 characters, and to store all of them in ASCII code requires a storage area of approximately 7 bytes, which is considerably smaller than the image memory 5. Therefore, as shown in FIG. 4(b), the sentences S1 are sequentially stored from the upper left of the character code memory 8, which serves as a page memory. Therefore, the sentence S2 is the second character code memory 8.
is stored in the same way. Normally, the character code memory 8 is A4
It can store about 10 pages of original size.

In this way, when the input of sentences St and S2 is completed,
The origin of the code information of the text data stored in the character code memory 8 is the coordinate St that has already been input.
(Xs 1 , Ys t), 32 (Xs2.Ys2
) and write in the image data area of the composite image formed in the image memory 5 using a high-definition character font of, for example, 40×40. This is image memory 5
This is because it stores bit data or image data, so it is composed of 1-bit plane or 2-bit plane. Note that the storage method in the character code memory 8 is handled in a common format with image data, which will be described later. Further, as a storage medium, a floppy disk or the like can be used in addition to an IC memory, and like image data, each text can be enlarged or reduced. Furthermore, if the display 3b is a color display, there is a risk that the text data will be distorted if the characters to be edited are thin. If you correct it, the text data will no longer be missing. Furthermore, the text data can be stored in the image memory 5 by specifying a color.

Next, the editing data input operation will be specifically explained with reference to the image layout shown in FIG. 4(c).

In this figure, A-D indicates the same thing as in Figure 3, and AI
(Xa, Ya) indicates the upper left coordinates of document A on the composite image, B, (Xb, Yb) indicate the upper left coordinates of document B on the composite image, and Ct (Xc 1. Y
c t ) indicates the upper left coordinates of the document C on the composite image, C2 (XC2, YO2) t'3 and C3 (Xa3
, Ya3) indicate the trimming coordinates of the image C. Z
R is the zooming ratio (hereinafter referred to as ZR), and Z
R=1 represents the same size.

First, while viewing the image processing menu shown in FIG. 5 displayed on the display 3a, the operator inputs editing data using the keyboard 3b according to the following procedure.

■ Determine the background color of the composite image from the R, G, and B values,
It is input from the keyboard 3b and displayed on the display 3a.

■ Position coordinates A1 (X
a, Ya) is determined, inputted from the keyboard 3b, and displayed on the display 3a.

(2) Determine Z R (=0.4), which determines the size of image A, and input it from the keyboard 3b to display it on the display 3a.

■ Position coordinates Bl (X

(2) Determine ZR (=0.5), which determines the size of image B, and input it from the keyboard 3b to display it on the display 3a.

■ Position coordinates C1 (Xc
t, Yc 1 ) is determined, input from the keyboard 3b, and displayed on the display 3a.

(2) Determine ZR (=0.5), which determines the size of image C, and input it from the keyboard 3b to display it on the display 3a.

■ Trimming position coordinates C2 (Xa2.Ya2) and C3 (Xa3°Yc 3 ) of image C
, enter it from the keyboard 3b and display it on the display 3a.
to be displayed.

Note that if the display 3a is capable of color display, the arrangement of images A to C to be edited on the display 3a according to each of the above steps is, for example, image A.

Give the frame of B a green color different from the base color, and create the image C.
When the entire screen corresponding to C (indicated by the broken line in Figure 4 (C)) is graphically displayed in light red, the overlapping parts of the images are displayed in yellow, the trimmed area of image C is graphically displayed in dark red, and the remaining parts are displayed in light red. The layout of the composite image can be easily grasped by erasing the portion of image C that was created and displaying the overlapping portion with image B in red. Further, when inputting the data of each image to the image processing menu displayed on the display 3a is completed, each data or parameter is stored in a designated register of the controller 2, which will be described later. Furthermore, each coordinate value may not be input directly but may be given as a parameter and generated internally. Also, for convenience, the trimming coordinate value is given as a rectangle, and in the case of a circle, it is given as radius and center coordinates.

Next, image editing work will be explained.

After creating the image processing menu, either manually load multiple originals one by one or use the automatic document feeder (ADF).
), each document is read by automatically setting the document, each time a document is read, the controller 2 and the pipeline processor 4 perform predetermined image processing, and write it to the image memory 5 according to the image processing menu. This operation is performed for all documents. By doing so, the editing work of the composite image is completed. In this manner, the present invention performs image editing based on the created image processing menu, so image processing can be performed in a short time without requiring a large capacity image file memory.

6(a) and 6(b) are diagrams illustrating the document reading principle of the present invention and enlarged views of essential parts, in which 11 is a document, 12 is a document feed roller, and 13 is a servo that drives the document feed roller 12.

Reference numeral 17 denotes a light receiving element constituting the image reading device 1, which includes an R stripe filter 18R, a G stripe filter 18G, and a B stripe filter 1.
There are three rows along 8B.

Next, the operation will be explained.

When the originals 11 are set in order according to the image processing menu, the servo motor 13 starts to drive at a rotation speed proportional to the ZR value, the original irradiation lamp 14 exposes the original 11, and the reflected light is transmitted through the mirror 15. scanned by the lens 16,
The focused reflected light passes through each stripe filter 18R, 18.
G and 18B are color separated and detected as image data by the light receiving element 17.

Next, the configuration of the controller 2 will be explained with reference to FIG. 7.

In this figure, 1, 4.5 indicate the same as in Figure 1, and 21
are selectors 22a, 2 for sorting image data detected by the light receiving element 17 of the image reading device 1 for each color;
2b is a 1-line memory that stores image data selected by the selector 21 for each pixel; 23 is a memory that sends the image data written in the 1-line memory 22a or 22b to the pipeline processor 4 for each color; Selector, 24, X clock generator, 25

is a zoom address counter that counts the clock f2 divided by the X clock frequency divider 26 and sends it to the selector 32.
a or selector 32b. 33 is an x register that stores the X component of the position coordinate input from the keyboard 3b, 34 is a Y register that stores the X component of the position coordinate input from the keyboard 3b, and 35a is the X address counter 29 and the X register. An adder 35b adds the address values of the X address counter 3o and the Y register 34, and an adder 36 stores the X component of the upper left coordinate of the trimming position input from the keyboard 3b. x2 register; 37 is a Y2 register that stores the X component of the upper left coordinate of the trimming position input from the keyboard 3b; 38a is a comparator that compares the address value of the adder 35a with the address value of the x2 register; 38b is the adder; 39 is an x3 register that stores the X component of the lower right coordinate of the trimming position input from the keyboard 3b; 4
0 is a Y3 register that stores the X component of the lower right coordinate of the trimming position input from the keyboard 3b, 41a is a comparator that compares the address value of the adder 35a with the address value of the x3 register, and 41b is the adder 35.
42 is a gate circuit, and 43 is a line feed mechanism that sets the drive speed of the servo motor 13 in accordance with the value of ZH. 44 is a read bus, and 45.46 is a write bus.

Next, the operation will be explained.

The light receiving element 17 of the image reading device 1 A/D converts the original 11 into 8-bit R, G, and B signals in synchronization with the clock fl generated by the .

22b via the selector 21. This write address is commanded to the X address counter 29, and the address value is sent to the selector 32a and selector 32b via the write bus 45, and is applied to, for example, the 1-line memory 22a that is being written. At this time,
In the 1-line memory 22b, the zoom address counter 3
1 reads out the stored image data according to the address value commanded via the readout bus 44, and
3 to the pipeline processor 4. In addition,
Clock f2 generated by zoom address counter 31
is generated by multiplying the clock f1 of the X clock generator 24 by 1/ZR by the X clock frequency divider 26. Therefore, when ZR>1, the frequency becomes f2 × fl, and Z
When R<1, the frequency becomes f2>f.

Next, the clock f1 is divided by 1/Z by the X clock frequency divider 26.
The reason for multiplying by R will be explained.

For example, when reducing the original size to ZR=0.5, that is, 172, and if the 1-line memory 22a is currently being written, the 1-line memory 22b will be read at the following read clock f2, f2=f, Xi /ZR=2f.

However, since it is written into the image memory 5 at the clock f1, the image data stored in the l-line memory 22b stored in the image memory 5 is read out twice. Therefore, the image size is reduced to 172 in the main scanning direction. Note that the clock f1 input to a terminal (not shown) of the binarization circuit 4e
The image data is latched with .

On the other hand, in the sub-scanning direction, the address value obtained by counting the clock F1 generated from the Y clock generator 25 by the Y address counter 3o is input to the Y address end of the image memory 5. In addition, the Y clock frequency divider 27 allows the clock F
1 is given from the ZR data register 28 (=0
．． Since the clock F2 obtained by multiplying 5) by 1/ZR is input as a pulse to the line feed mechanism 43, the feed speed of the servo motor 13 is doubled. At this time, the light receiving element 17 reads the original 11 in synchronization with the clock f generated by the X clock generator 24.

The image data is thinned out line by line, and the overall sub-scanning direction is reduced to 1/2. In addition.

Clock F2 and clock f2 are programmable P
It can be easily generated using an LL circuit.

Next, parallel movement of image data will be explained.

Since the X component of the position coordinate input from the keyboard 3b is stored in the X register 33 and the Y component in the Y register 34, the respective address values are stored at the X address end of the image memory 5 via adders 35a and 35b. , Y address end, and the image data is shifted in parallel.

Next, the image data trimming operation will be explained.

X of the top left coordinate of trimming input from keyboard 3b
The component is stored in the X register 36, the Y component in the Y register 37, the X component of the lower right trimming coordinate input from the keyboard 3b is stored in the X register 39, and the Y component is stored in the Y register 40. , each comparator 35a.

35b and comparators 41a and 41b, the gate circuit 42 generates a trimming window and sends a write enable signal (WE) to the image memory 5. In this way, the image is reduced based on the image processing menu table created initially.

Edited image data that has been edited such as enlargement, position movement, and compositing is stored in the image memory 5, so image editing other than creating an image processing menu table only requires setting the original, which is faster than a normal page-up system. The speed is increased, and editing work becomes real-time processing.

Next, a description will be given of a plurality of image editing operations for different document sizes.

If the original sizes are different as shown in Figure 8, the original size (vertical, horizontal) of each image Al + Bl * CI must be considered, and the following (I)
The document size can be detected by the method of ~(I[).

(I) The original size of the image At*Bl+c is set to, for example, A4. B4. Directly enter a standard size such as A5 or a length such as 210mm x 297+am.

(■) Image At using a digitizer.

Input the coordinates of the four corners or two diagonal points of B, C, and the size of each document is automatically recognized.

(II[) Image Al + Bl + c, respectively, are optically scanned and the original size is recognized. Among the methods (I) to (II) above, in the method (I), the operator always inputs data. It is necessary, time-consuming, and there is a high possibility of input errors. Also,
(II) requires a digitizer, so
The cost will be high. Therefore, in this invention, the one based on (I[[) is adopted. The document size detection operation using (I[[) will be described below.

FIG. 9 is an internal sectional view showing the mechanism of the document size detection means of the present invention, and 11, 14, 15°, 16.17 are the 6th

It is assumed that the four corners of the document 11 are white.

Next, the operation will be explained.

A light absorber 53 is placed so as to cover the entire upper surface of the original 11 placed on the original table glass 52, and the optical system unit 5
1 is blisscanned at high speed prior to image detection, the image level is detected by the light receiving element 17 as shown in FIG. 1O. That is, level transition points t1 and t2 are created at the boundary between the dark level point DL indicating the level of the light absorber 53 and the white level point WL indicating the level of the original 11, and the level transition points t1 and t2 are By counting the time with a counter (not shown), the horizontal length a and the vertical length of the document 11 can be detected, and the document size can be recognized from this.

Note that a mirror surface is used instead of the light absorber 53, and the irradiation lamp 1
The light receiving element 17 detects the diffusion of the light emitted from 4, and the counter detects the level transition point t1 and the level transition point 2 above the level transition point.
Alternatively, if the original 11 is black, a blank sheet of paper, which is a perfect light reflector, may be used instead of the light absorber 53.

Next, the setting of the zoom ratio for the detected horizontally long a and vertically long edited images will be explained.

If the horizontal length a' and vertical length b' of each document 11 in the edited image are entered into the image processing menu displayed on the display 3a of the monitor section 3 using the keyboard 3b before the above-mentioned Briscan, the light receiving element 17 will detect the The horizontal zoom ratio ZRh and the vertical zoom ratio ZRv are calculated from the horizontal and vertical dimensions as follows: ZRh=a'/a ZRma=b'/b Set for each horizontal and vertical direction. are respectively stored in zoom ratio registers (not shown).

By performing this operation on each document 11, editing data is written to the image processing menu. Note that the horizontal zoom ratio ZRh and vertical zoom ratio ZRv stored in the zoom ratio register are If the difference is large, the edited image will be distorted, so the Max
ZR (ZRh.

Image distortion can be prevented by taking ZRv) and storing the larger one in both zoom ratio registers.

Next, color processing of image data will be explained with reference to FIG.

The minimum value of the density data C, M, and Y is detected by the minimum value detection circuit 62a of the UCR black circuit 62 at the next stage, and the gray component (unsupported color component) is extracted. The minimum value is non-linearly converted by the UCR/γ circuit 62b and the signal whose sign is inverted is sent to the adder 62C1.
m, is input to the adder 62y, subtracted from the image data C, M, and Y, and the image data C is sent to the primary stage masking circuit 63.

Next, the CPU 6 inputs the γ conversion coefficients α, β, and n shown in FIG. 12(b) that have already been input from the keyboard 3b.
For example, 5 performs the following calculation for each density data, x'=α(X-β)nx>β=Ox<β. 64 RAM64c, RAM64m,

(S3), then determine the end of the image data (S4)
, if No, the process returns to step S2, and if YES, the process ends. The above operations are performed simultaneously with the input of the editing data, and the masking coefficients and γ conversion coefficients are input coded based on color samples arbitrarily determined for a certain conversion.

In this way, image reading → image editing → binarization (multi-value conversion)
→Since the storage operation to the image memory 5 is performed based on the editing data, image editing is speeded up.

Note that in the above embodiment, the edge enhancement processing section 4c and the masking processing section 4d that constitute the pipeline processor 4 are
