Description

DETAILED DESCRIPTION OF THE INVENTION (N IJJ's technical part Yf) This invention is based on the so-called rough layout direction /1<+' in printing H magazines, catalogs, etc. and shooting instructions 1 inch, etc. from CJi4; The present invention relates to a method for extracting image contours in a printing system that uses an interactive computer to improve efficiency when creating 1+1 designated paper.

(Technical aspect of the invention: ``r JJJ and its problems) To create a copy for printing, it is necessary to prepare a designated sheet with 113 markings indicating the true layout and the position of the copy. be.

For this reason, designers and the like need to arrange the photographs and characters and the contents of the photographs (layout of the subject) according to the line 1 required for the printed matter. Since design work inevitably involves revisions, corrections are made each time, and in the past, it took a lot of time and effort to obtain the final layout designation. In other words, the 6th
The figure shows the layout of various prints of today's Sessha that can be seen in magazines, books, catalogs, pamphlets, etc., and is based on the project plan +00 that commercializes various information and project images. In addition to creating a shooting instruction sheet that summarizes the contents of the meeting such as photos and shadows, we also include copies of detailed explanations and explanations, taking into consideration the layout and shape, and how to create an overall image pattern. A rough draft is created by creating a layout instruction Qlj for configuring 7, and performing a so-called rough work 101 in which various considerations are made to make it suitable as a product. Based on this rough draft,
A copywriter 102 creates a character manuscript (copy) 103 that fits within a predetermined space, and uses a phototypesetting machine or the like to type it into phototypesetting characters +04, while a cameraman 108
Photographs are taken according to the rough manuscript, and color manuscripts (photos) are taken.
109 is created, and the designer +05 prints a pattern or photo trimmed to a predetermined size 5 from the color original 103 and the rough original 101, and prints it on designated paper (picture pattern) 10 with -13.
Create B. After that, these layout designation sheets 106. Color manuscript 109. Phototypesetting character +04 is Finishman 11
It was collected all at once after 0, and further examination was added to partially correct 11:.

After being applied, the phototypesetting characters 104 are pasted on a mount 1111-, made into a printing plate 112 using the printing machine 1, and printed in relief 113, and later printed as a negative! It will be made into 14. Further, the specified paper 106 with -1 and the color original (photo) 108 receive a finger from the finisher 110, and the operator 115 scans Y (yellow) 1M (
After the colors are separated into (magenta), C (cyan) and BK (black), they are finally combined (117) with the L negative +14 to become a film master +18, which is then sent to plate making and printing (8119) for printing. It has become.

In this way, in the conventional system, layout instructions in the process of realizing printed matter from a plan, 4; or photographing instructions; rough work of JI; ′! When extracting only the outline of a document (image) to match the quality of the image, this is done in one operation.
There is a strong desire to improve the efficiency of these relatively monotonous repeated trial-and-error tasks.

(LJ aspect of the invention) This originating IJJ was made from the °1 list as described in I-1, and the layout is based on the rough manuscript such as layout instructions or photographing instructions when creating a printed manuscript. An image in a printing system that can automatically create specified paper using an interactive computer, obtain final instructions quickly and accurately, and further create a printing mount based on this information. The purpose of this paper is to provide a method for extracting contours.

(Summary of the Invention) The present invention relates to a method for positioning figures for designated layout paper in a printing system.

A layout designation sheet for printing is created using an interactive CRT display device consisting of a menu display section from which various command menus can be selected and a display screen section that displays images corresponding to the contents of the menu. In a printing system for drawing a layout for a printing system, the above-mentioned image is displayed on both sides of the display to create a layout, and the outline of the above-mentioned image is determined by searching by scanning the image in the horizontal and vertical directions, and the outline of the above-mentioned image is extracted. This is how it was done.

(Embodiment of Part II) The eleventh part is a block diagram showing an embodiment of the present invention, in which a computer (CPU) 3 performs overall control.
The CPU 30 has 11 functions that are generally referred to as mini-computers.
An E storage device 31 and an auxiliary storage device 32 such as a floppy disk, a hard disk, and an optical disk are connected via a pass line, as well as a TV camera, scanner, and COD.
An image input device 33 such as a scanner is an interface 33^
connected via. Also, Seiden plotter.

XY plotter, laser beam printer Jun output device 34
is connected via an interface 34A, and a keyboard 35 for manually inputting necessary data and commands is connected. Such an image processing system is connected to a display system of a graphic display via interfaces 38A and 16B, and one display system is provided with a display controller 40 consisting of a microprocessor or the like that controls the overall display. Connected to this display controller 40 are a frame memory 41, a CRT display device 2142 capable of thick display, and an input device 43 such as a tablet, mouse, light bezel, etc. that functions as a man-machine interface. The present invention aims to improve the efficiency of this work by automatically and quickly extracting the outline of a photographic original or image using a book having such a structure.

In such a U1 configuration, in the present invention, first, a layout frame 50 as shown in FIG. 2 is displayed on the CRT display device 42 by a method that will be described later. As shown in the figure, this display frame 50 includes a menu display 19500 in which a desired command menu (for example, AIO command for copy registration, All command for copy setting, etc.) is prepared and the desired command can be selected with a single touch, and a command Menu At, A2. A3. According to..., the Dinobu 1F 4 screen section 600 can display a picture area, a copy area, etc. on the screen 1 and perform various operations in an interactive format.
The configuration is as follows. This layout frame 50 is
For peace of mind, the A new table small section 500 and the display screen section 600 can be changed to any size. In the present invention, the image 801 displayed on the display screen section 600 can be changed to display only the outline portion, such as one image 602, by lightly touching the menu display section 500 with the command menu "A19 Extraction of contours" with the light pen. can do.

Figures 3 (A) and (B) show the coordinates of pixels on the force planes al to an and the force planes b1 to bn of the tree, respectively, and the black circles between the two marks (hereinafter referred to as 1 mark). The mark indicates that it will be displayed as an image. Here, the outline of the image in Figure (A) becomes as shown in Figure (B). In other words, the principle of this invention is to sequentially scan the water mop and the vertical force surface, and when the image moves from the 1 mark to the target. Record the intention of , and the intention when it moves from intention to 1 mark as F-Zo (in circle 9), and then record the intention as F-zo (in circle 9), and
g1(l) If either of the scanning conditions does not satisfy the above conditions, it will not be registered as an edge.

FIG. 4 is a flowchart for explaining the present invention in detail, starting with 4+, +z force direction scanning (steps St, S2), scanning by -pixel (step S3), and scanning if the pixel is white. (step S4),
If the scanning of that water line has not finished r (reached the final end) (step 55), the first pixel is scanned (step S6), and to determine whether that pixel is black or white (step S7), if it is white, If the pixel is black, that pixel is not registered as an edge (step S8), and if it is black, that pixel is used as an edge (step 514).In step S4, one pixel is black and scanning of that water line has ended. If not, scan the next pixel (step 5ll) and determine whether that pixel is black or white (step 5I2). If it is black, it means that black pixels are continuous, so this pixel is not registered as an edge ( Step 51
3) If it is white, set the black pixel immediately before it to 0 as the edge.
Record. Also, by scanning in the water f direction, it is possible to
If it reaches 1 (step S5 and H5IO), 11)
water f, scanning is performed from the beginning (step Sl
, S2), and when all water scanning is completed (step Sl), overlapping scanning is performed next. This is a flowchart similar to the Mizuyani scanning described in 1-1, and when the pre-scanning finally ends (step 515), the contour extraction work ends.
becomes. And water 41 or 11'! Pixels registered as edges by 1cI scanning form the outline of the image.

FIGS. 7A to 7D are diagrams for explaining the conventional contour extraction method υ, which is an image processing method called 3X3 matrix. This is to register all pixels as a contour only when 3x3 pixels are classified as one unit, and white → black or black → white. It is not registered as a contour, but is recorded as a partial contour in (C:) and (D) of the same figure. In this way, since the contour is searched while shifting one pixel at a time, nine times are required to perform the process for each pixel. On the other hand, according to the present invention 11, it is sufficient to perform scanning twice per l+il'iJG, in the water direction and in the heavy direction, which significantly shortens the processing time. Part 1-5
Is this IJJ from IJJ much easier to log? With r, software development time can be reduced by i+f.

In addition, here, the contour image was extracted using one pixel according to the contour of the original image, but it is also possible to make the contour line thicker by drawing two strokes 2 in succession, and the contour line can also be made thicker than the original image. It is possible to extend the image by one pixel toward the outer periphery or retract it toward the inner periphery. In other words, it can be easily made one size larger or smaller.

Once complete images and figures and their positions are completed as described above, they are stored in the auxiliary storage device 32 according to the flowchart in FIG. 5 (step 552).
, make a hard copy on paper etc. using the output device 34 (stay 2
The hard copy thus obtained from the output device 34 is used as the layout designation sheet 108 in the mark 1. Furthermore, here t'+1. A part of the information obtained can be used as a printing mount f'l Narukawa newsletter, and based on this information, a printing mount is created using a drawing machine. In addition, when creating a pattern manually, by treating the color b; draft as a pattern, the additional information can be used as JA designated paper.

(Effects of the invention) As shown in I- below, in this development III, the layout designation sheet is created through a trial and error process of materializing the plan f+'
