Description

[Detailed Description of the Invention] (Technical Field of the Invention) The present invention provides layout instructions and photographing instructions for printing 31 magazines, catalogs, etc., and an interactive method when creating layout designated sheets from so-called rough manuscripts such as 43. The present invention relates to a method for trimming binary information images in a printing system that uses a computer to improve efficiency.

(Technical background of the invention and its problems) In order to create a photographic manuscript for printing, it is necessary to create a layout designation sheet that indicates the arrangement of photographs and the position of copies thereof. For this reason, designer Kaya must hand-write the arrangement of photographs and characters and the contents of the photograph (layout of the subject) according to the conditions required for the printed matter. Since design work inevitably involves revisions, manual rewriting is required each time, and in the past, it took a lot of effort and time to obtain the final layout designation sheet. In other words, Figure 7 shows how layouts are created for today's wide variety of printed materials such as magazines, bookshelves, catalogs, pamphlets, etc., and shows 100 project proposals for commercializing various information and project images.
Based on this, we create a shooting instruction sheet that summarizes the contents of meetings such as photography, and also include copies of specific explanations and explanations, taking into consideration the layout and shape, and how to create the overall image pattern. A rough draft is created by creating a layout instruction sheet for configuring the product, and performing a so-called rough work 101 in which various considerations are made to ensure that the product is appropriate. Based on this rough manuscript, the copywriter 102 creates a character manuscript (copy) 103 that fits within a predetermined space, and typesets it into phototypesetting characters 104 using a phototypesetting machine or the like. On the other hand, the cameraman 108 takes pictures according to the rough manuscript, and creates a color original m (photo)! Create 09 and designer 105
The layout designation sheet (picture pattern) 10B is created by placing a pattern or photograph trimmed to a predetermined size from the color original 109 and the rough original 101. After that, these layout designation sheets 10B, color original 109. The phototypesetting characters 104 are collectively collected under the finisher 110, and after further examination and some corrections are made, the phototypesetting characters 104
is pasted on the mount 111 and printed as 1st block using a 1st block drawing machine etc.
12, convex photography 113, and later negative 114. In addition, layout designation paper 10B and color original m (
Photo g) 103 receives an instruction from the finisher 110 and is separated into Y (yellow), 1M (magenta), C (cyan) and BK (black) by the scanner 11B by the operator 115, and then is separated into the negative 114 and the above-mentioned negative 114. Finally, I&ll? It was made into film A version 11B, and the plate making and
It is sent to a printing process 119 and printed.

In this way, in conventional systems, a lot of time is spent on rough work on layout instructions or shooting instructions in the process of turning a plan into a printed matter, as well as on trimming images when laying out the designated 106-sheet paper 106. Therefore, there is a strong desire to improve the efficiency of this work.

(Object of the invention) This invention was made under the above circumstances,
When creating a print manuscript, it is possible to quickly and accurately obtain final instructions by automatically creating layout-designated sheets using an interactive computer based on rough drafts such as photographing instructions. It is an object of the present invention to provide a method for trimming a binary information image in a printing system which can also create a printing mount based on this information.

(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 CR7 display device consisting of a menu display section that allows selection of various command menus and a display screen section that displays images corresponding to the contents of the menu. In this printing system, an image is displayed on the display screen to create a layout, and a boundary line in a desired trimming range for one image is determined by integer calculation.

(Embodiment of the Invention) FIG. 1 is a block diagram showing an embodiment of the invention, in which a computer (CPU) 30 performs overall control.
The CPt 130 has a function that is generally referred to as a mini-computer, and is preferably capable of processing basic line drawings with medium bits.
131 and an auxiliary storage device 32 such as a floppy disk, hard disk, or optical disk are connected via a path line, and an image input device 33 such as a TV camera, scanner, or CCN scanner is connected via an interface 33A. Further, an output device 34 such as an electrostatic plotter, an XY plotter, a laser beam printer, etc. 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 an interface 38A.
and 368 to the display system of the graphic display, and the display system is provided with a display controller 40 consisting of a microprocessor or the like that performs overall display control.

A CART display device 42 capable of displaying the original size and an input device 43 such as a tablet, mouse, light pen, etc., which can be used as a man-machine interface, are connected. With this configuration, the present invention aims to improve the efficiency of the work of determining the trimming range of an image in creating the layout designation sheet 10Ei.

In such a configuration, in the present invention, first, a layout frame 50 as shown in FIG. 2 is displayed on the CR7 display device 42 by a method that will be described later.

As shown in the figure, this display frame 50 includes a menu display section 500 in which a desired command menu (for example, AIO command for copy registration, All command for copy setting, etc.) is prepared and a desired command can be selected with one touch; Command menu AI, A2. A3. A display screen unit 60 that can display a picture area, a copy area, etc. on the screen and perform various tasks in an interactive manner according to...
The configuration is divided into 0 and 0. This layout frame 50 can be used to display a menu if necessary? B500 and display screen section 800 can be changed to any size.

By the way, if it is necessary to change, modify, move, or delete the display position of a layout figure that has been input and displayed, for example, use a light pen to move or delete it from the menu display section 500.
By lightly touching the desired command menu (for example, touching the AI command in the case of a split command), the corresponding content is displayed in color on the display screen section 600 or the menu display section 500 in real time,
It has become so.

Here, an image 601 is displayed on the display screen section 6oo.
is displayed, first press “A1” in the menu display area.
This trimming method allows you to obtain, for example, a circular trimmed image like image 802 by specifying the 9 trimming command, specifying the trimming range, and deleting the unnecessary part (“A19 delete” command). This is the gist of the invention. The purpose is to find the boundary line of this trimming figure at high speed using M counting, and first, a case where the boundary line is a straight line will be explained.

The third rgJ is x, x+1. Vertical line of x+2... and L7+
Each pixel (pixel) at the intersection with the horizontal line of l, y+2...
It is assumed that there exists an ideal straight line l, and is a diagram for explaining how the straight line is approximated by what pixel arrangement. First, the pixel Ql at the intersection of As this legal method, which only needs to be displayed, first, the ideal point PI(!1.
If the error for y is e for y, then the error el for the next ideal point P2 (X2.Y2) is el =
e + (y2 − 71)/ (x2 −
! 1) It can be expressed as (1), and if this error el is larger than 0.5, the point (x
+1. y÷1) is displayed, and if it is smaller than 0.5, a point (
X÷1. y) should be displayed. Of course, this “0.
If 5'' is doubled and set to 1, it can all be processed using integer calculations.

Next, a method for determining a boundary line when the trimming figure is a circle will be explained with reference to FIGS. 4(A) to 4(D). In this case, as shown in FIG. 5, the circle is divided into eight equal parts at 45° intervals, one of the sections Kl is found, and the rest can be found by utilizing symmetry to find the entire circle.

In this section Kl, 4 in Fig. 3 (A) to ([1)

Then, Ti,l should be adopted as the next point, and if dl-+<0, 51.1 should be adopted as the next point.0th order.In the case of the same figure (D), Ti・1 should be adopted as the next point. can be seen from the same figure, but in this case, dl・+>O holds true.Therefore, if we summarize the cases of 1 or more, in any case, dl
・If bird≧O, then 〒1.1 should be adopted as the next point, and if di・1×0, then Sl and I should be adopted as the next points. In other words, by calculating equations (5), (8), and (7) and determining the sign of dl, 1, the ideal circle curve L2~
A point close to L6 can be adopted.

All calculations in this case are discriminant calculations, and! ! ! Can be processed by numerical calculations. If all calculations can be performed using integer types in this way, the disadvantages of real number calculations, such as rounding errors and long calculation times, will disappear. Once the boundary line of the trimming figure has been determined, unnecessary parts are deleted as described above to obtain a trimmed image such as 1 stroke *eo2. The position of each figure is determined by moving this trimmed image as appropriate.

When the complete positioning of the figure is performed as described above, it is stored in the auxiliary storage device 32 according to the flowchart of FIG. 6 (step 552),
A hard copy is made on paper or the like (step 551), and the hard copy thus obtained from the output device W134 is used as the layout designation sheet 106 for printing. Further, part of the information created here can be used as information for creating a printing mount, and a printing mount is created using a drawing machine based on this information. Also.

When inputting a picture pattern, by treating the color original as a picture pattern, processing information can also be used as layout designation paper.

(Effects of the Invention) As described above, according to the method of the present invention, the task of creating layout designation sheets, which is a process of trial and error, from a plan to realization can be computerized from the conventional manual work.

Automation enables high-speed, accurate processing in real time to improve efficiency, and has the great advantage of being able to quickly respond to today's wide variety of printing demands.
